A muscle fiber consists of just one https://salamladc.org/buy-cipro-pill/ cell, generic cipro online for sale but many nuclei. A team at the MDC led by Professor Carmen Birchmeier has now shown just how varied these nuclei are. The study, which has been published in Nature Communications, generic cipro online for sale can help us better understand muscle diseases such as Duchenne muscular dystrophy.Usually, each cell has exactly one nucleus.
But the cells of our skeletal muscles are different. These long, fibrous cells have a comparatively large cytoplasm that contains generic cipro online for sale hundreds of nuclei. But up to now, we have known very little about the extent to which the nuclei of a single muscle fiber differ from each other in terms of their gene activity, and what effect this has on the function of the muscle.A team led by Professor Carmen Birchmeier, head of the research group on Developmental Biology / Signal Transduction at the Max Delbrueck Center for Molecular Medicine in the Helmholtz Association (MDC), has now unlocked some of the secrets contained in these muscle cell nuclei.
As the researchers report in the journal Nature Communications, the team investigated the gene expression generic cipro online for sale of cell nuclei using a still quite novel technique called single-nucleus RNA sequencing -- and in the process, they came across an unexpectedly high variety of genetic activity.Muscle fibers resemble entire tissues"Due to the heterogeneity of its nuclei, a single muscle cell can act almost like a tissue, which consists of a variety of very different cell types," explains Dr. Minchul Kim, a postdoctoral researcher in Birchmeier's team and one of the two lead authors of the study. "This enables the cell to fulfill its numerous tasks, like communicating with neurons or producing certain muscle proteins."Kim undertook the majority of the experimental work in the study, and his data was also generic cipro online for sale evaluated at the MDC.
The bioinformatics analyses were performed by Dr. Altuna Akalin, head of the Bioinformatics and Omics Data Science Platform at the MDC's generic cipro online for sale Berlin Institute of Medical Systems Biology (BIMSB), and Dr. Vedran Franke, a postdoctoral fellow in Akalin's team and the study's co-lead author.
"It was only thanks generic cipro online for sale to the constant dialogue between the experiment-based and theory-based teams that we were we able to arrive at our results, which offer important insight for research into muscle diseases," emphasizes Birchmeier. "New techniques in molecular biology such as single cell sequencing create large amounts of data. It is essential that computational labs are part of the process early generic cipro online for sale on as analysis is as important as data generation," adds Akalin.
advertisement Injured muscles contain activated growth-promoting genesThe researchers began by studying the gene expression of several thousand nuclei from ordinary muscle fibers of mice, as well as nuclei from muscle fibers that were regenerating after an injury. The team genetically labeled the nuclei and isolated them from the cells. "We wanted to find out whether a difference in gene activity could be observed between the resting and the growing muscle," says Birchmeier.And generic cipro online for sale they did indeed find such differences.
For example, the researchers observed that the regenerating muscle contained more active genes responsible for triggering muscle growth. "What really astonished us, however, was the generic cipro online for sale fact that, in both muscle fiber types, we found a huge variety of different types of nuclei, each with different patterns of gene activity," explains Birchmeier.Stumbling across unknown nuclei typesBefore the study, it was already known that different genes are active in nuclei located in the vicinity of a site of neuronal innervation than in the other nuclei. "However, we have now discovered many new types of specialized nuclei, all of which have very specific gene expression patterns," says Kim.
Some of these nuclei are located in clusters close to other cells generic cipro online for sale adjacent to the muscle fiber. For example, cells of the tendon or perimysium -- a connective tissue sheath that surrounds a bundle of muscle fibers. advertisement "Other specialized nuclei seem to control local metabolism or protein synthesis and are distributed generic cipro online for sale throughout the muscle fiber," Kim explains.
However, it is not yet clear what exactly the active genes in the nuclei do. "We have come across hundreds of genes in previously unknown small groups of nuclei in the muscle fiber that appear to be activated," reports Birchmeier.Muscle dystrophy seemingly causes many nuclei types to be lostIn a next step, generic cipro online for sale the team studied the muscle fiber nuclei of mice with Duchenne muscular dystrophy. This disease is the most common form of hereditary muscular dystrophy (muscle wasting) in humans.
It is caused by a mutation on the generic cipro online for sale X chromosome, which is why it mainly affects boys. Patients with this disease lack the protein dystrophin, which stabilizes the muscle fibers. This results in the cells gradually dying off."In generic cipro online for sale this mouse model, we observed the loss of many types of cell nuclei in the muscle fibers," reports Birchmeier.
Other types were no longer organized into clusters, as the team had previously observed, but scattered throughout the cell. "I couldn't believe this when I first saw it," she recounts. "I asked my team to repeat the generic cipro online for sale single-nucleus sequencing immediately before we investigated the finding any further." But the results remained the same.The mouse nuclei resemble those of human patients"We also found some disease-specific nuclear subtypes," reports Birchmeier.
Some of these are nuclei that only transcribe genes to a small extent and are in the process of dying off. Others are generic cipro online for sale nuclei that contain genes that actively repair damaged myofibers. "Interestingly, we also observed this increase in gene activity in muscle biopsies of patients with muscle diseases provided by Professor Simone Spuler's Myology Lab at the MDC," says Birchmeier.
"It seems this is how the muscle tries to counteract the disease-related damage.""With our study, we are generic cipro online for sale presenting a powerful method for investigating pathological mechanisms in the muscle and for testing the success of new therapeutic approaches," concludes Birchmeier. As muscular malfunction is also observed in a variety of other diseases, such as diabetes and age- or cancer-related muscle atrophy, the approach can be used to better research these changes too. "We are already planning further studies with other disease models," Kim confirms.Depression is a mental disorder that affects more than 264 generic cipro online for sale million people of all ages worldwide.
Understanding its mechanisms is vital for the development of effective therapeutic strategies. Scientists from generic cipro online for sale the Institut Pasteur, Inserm and the CNRS recently conducted a study showing that an imbalance in the gut bacterial community can cause a reduction in some metabolites, resulting in depressive-like behaviors. These findings, which show that a healthy gut microbiota contributes to normal brain function, were published in Nature Communications on December 11, 2020.The bacterial population in the gut, known as the gut microbiota, is the largest reservoir of bacteria in the body.
Research has increasingly shown that the host and the gut microbiota are an excellent example of systems with mutually beneficial interactions generic cipro online for sale. Recent observations also revealed a link between mood disorders and damage to the gut microbiota. This was demonstrated by a consortium of scientists from the Institut Pasteur, the CNRS and Inserm, who identified a correlation between the gut microbiota and the efficacy of fluoxetine, a generic cipro online for sale molecule frequently used as an antidepressant.
But some of the mechanisms governing depression, the leading cause of disability worldwide, remained unknown.Using animal models, scientists recently discovered that a change to the gut microbiota brought about by chronic stress can lead to depressive-like behaviors, in particular by causing a reduction in lipid metabolites (small molecules resulting from metabolism) in the blood and the brain.These lipid metabolites, known as endogenous cannabinoids (or endocannabinoids), coordinate a communication system in the body which is significantly hindered by the reduction in metabolites. Gut microbiota plays a role in brain function and mood generic cipro online for sale regulationEndocannabinoids bind to receptors that are also the main target of THC, the most widely known active component of cannabis. The scientists discovered that an absence of endocannabinoids in the hippocampus, a key brain region involved in the formation of memories and emotions, resulted in depressive-like behaviors.The scientists obtained these results by studying the microbiotas of healthy animals and animals with mood disorders.
As Pierre-Marie Lledo, Head of the Perception and Memory Unit at the Institut Pasteur (CNRS/Institut Pasteur) and joint last author of the study, explains. "Surprisingly, simply transferring the microbiota from an animal with mood disorders to an animal in good health was enough to bring about biochemical changes and confer depressive-like behaviors in the latter."The scientists identified some generic cipro online for sale bacterial species that are significantly reduced in animals with mood disorders. They then demonstrated that an oral treatment with the same bacteria restored normal levels of lipid derivatives, thereby alleviating the depressive-like behaviors.
These bacteria could generic cipro online for sale therefore serve as an antidepressant. Such treatments are known as "psychobiotics.""This discovery shows the role played by the gut microbiota in normal brain function," continues Gérard Eberl, Head of the Microenvironment and Immunity Unit (Institut Pasteur/Inserm) and joint last author of the study. If there is generic cipro online for sale an imbalance in the gut bacterial community, some lipids that are vital for brain function disappear, encouraging the emergence of depressive-like behaviors.
In this particular case, the use of specific bacteria could be a promising method for restoring a healthy microbiota and treating mood disorders more effectively. Story Source generic cipro online for sale. Materials provided by Institut Pasteur.

Now researchers have found several answers to what makes hard workouts so effective."Our research on rats with heart failure shows that exercise reduces the severity of the disease, improves heart function and increases work capacity.
And the intensity of the training is really importance to achieve this effect," says Thomas Stølen, a researcher at the Norwegian University of Science and Technology (NTNU).Stølen and his colleague Morten Høydal are the main authors of a comprehensive study published in the Journal of Molecular and Cellular Cardiology. The researchers went to great lengths to investigate what happens inside tiny heart muscle cells after regular exercise."We found that exercise improves important properties both in the way heart muscle cells handle calcium and in conducting electrical signals in the heart. These improvements enable the heart to beat more vigorously and can counteract life-threatening heart rhythm disorders," says Stølen.For a heart to be able to beat powerfully, regularly and synchronously, a lot of functions have to work together.
Each time the heart beats, the sinus node -- the heart's own pacemaker -- sends out electrical impulses to the rest of the heart. These electrical impulses are called action potentials.All the heart muscle cells are enclosed by a membrane. At rest, the electrical voltage on the inside of the cell membrane is negative compared to the voltage on the outside.
The difference between the voltage on the outside and the inside of the cell membrane is called the resting membrane potential. advertisement When the action potentials reach the heart muscle cells, they need to overcome the resting membrane potential of each cell to depolarize the cell wall. When this happens, calcium can flow into the cell through channels in the cell membrane.Calcium initiates the actual contraction of the heart muscle cells.
When this process is complete, calcium is transported out of the cell or back to its storage site inside each heart muscle cell. From there, the calcium is ready to contribute to a new contraction the next time an action potential comes rushing by.If the heart's electrical conduction or calcium management system fails, the risk is that fewer heart muscle cells will contract, the contraction in each cell will be weak, and the electrical signals will become chaotic so that the heart chambers begin to flutter."All these processes are dysfunctional when someone has heart failure. The action potentials last too long, the resting potential of the cells is too high, and the transport function of the calcium channels in the cell wall is disturbed.
Calcium then constantly leaks from its storage places inside every heart muscle cell," Stølen says.Before Stølen gives us the rest of the good news, he notes, "Our results show that intensive training can completely or partially reverse all these dysfunctions."Normally, the sinus node causes a human heart to beat between 50 and 80 beats every minute when at rest. This is enough to supply all the organ systems and cells in the body with as much oxygen-rich blood as they need to function properly. advertisement When we get up to take a walk, our heart automatically starts beating a little faster and pumping a little harder so that the blood supply is adapted to the increased level of activity.
The higher the intensity of the activity, the harder the heart has to work.Exercise strengthens the heart so it can pump more blood out to the rest of the body with each beat. Thus, the sinus node can take it a little easier, and well-trained people have a lower resting heart rate than people who have not done regular endurance training.At the other end of the continuum are people with heart failure. Here the pumping capacity of the heart is so weak that the organs no longer receive enough blood to maintain good functioning.
People with heart failure have a low tolerance for exercise and often get out of breath with minimal effort.In other words, increasing the pumping power to the heart is absolutely crucial for the quality of life and health of people with heart failure.Many of the more than 100,000 Norwegians who live with heart failure have developed the condition after suffering a major heart attack -- just like the rats in Stølen and Høydal's study.In the healthy rats, the heart pumped 75 percent of the blood with each contraction. In rats with heart failure, this measure of pump capacity, called ejection fraction, was reduced to 20 per cent, Stølen says.The ejection fraction increased to 35 percent after six to eight weeks with almost daily interval training sessions on a treadmill. The rats did four-minute intervals at about 90 percent of their maximum capacity, quite similar to the 4 à 4 method that has been advocated by several research groups at NTNU for many years."The interval training also significantly improved the rats' conditioning.
After the training period, their fitness level was actually better than that of the untrained rats that hadn't had a heart attack," says Stølen.Impaired calcium handling in a heart muscle cell not only causes the cell to contract with reduced force every time there is an action potential. It also causes the calcium to accumulate inside the fluid-filled area of the cell -- the cytosol -- where each contraction begins.The calcium stores inside the cells are only supposed to release calcium when the heart is preparing to beat. Heart failure, however, causes a constant leakage of calcium out of these stores.
After each contraction, calcium needs to be efficiently transported back into the calcium stores -- or out of the heart muscle cell -- via specialized pumps. In heart failure patients, these pumps work poorly.When a lot of calcium builds up inside the cytosol, the heart muscle cells can initiate new contractions when they're actually supposed to be at rest. An electrical gradient develops which causes the heart to send electrical signals when it shouldn't.
This can cause fibrillation in the heart chambers. This ventricular fibrillation is fatal and a common cause of cardiac arrest."We found that interval training improves a number of mechanisms that allow calcium to be pumped out of the cells and stored more efficiently inside the cells. The leakage from the calcium stores inside the cells also stopped in the interval-trained rats," says Stølen.The effect was clear when the researchers tried to induce ventricular fibrillation in the diseased rat hearts.
They only succeeded at this in one of nine animals that had completed interval training. By comparison, they had no problems inducing fibrillation in all the rats with heart failure who had not exercised.So far, the research group had shown that exercise improves calcium management in diseased heart muscle cells in several ways. The training also makes the electrical wiring system of the heart more functional.In addition, they showed that exercise counteracted processes that cause the heart to become big and stiff.Taken together, these improvements make each heartbeat more powerful and reduce the severity of heart failure.
The risk of dangerous ventricular fibrillation was also reduced.But Stølen and team still lacked an answer to why exercise corrects slow action potentials and ensures that the heart muscle cells are able to take care of calcium in the right way.Therefore, they investigated whether the training had altered the genetic activity inside the rat cells. Thousands of different types of micromolecules called micro-RNA probably control most of this activity through direct interaction with genes."It turned out that 55 of the micro-RNA variants we examined were altered in rats with heart failure compared to the healthy rats. Interval training changed 18 of these back towards healthy levels.
Several of the relevant micromolecules are known to play a role in both calcium management and the electrical conduction system of the heart, but the most interesting thing is that we discovered new micro-RNAs that can play an important role in heart failure," says Stølen.This article has mostly considered the effects of high-intensity interval training. But the study also includes a group of rats that trained more sedately.The rats in this group ran the same distance and thus did as much total training work as the rats in the interval training group. However, they had to exercise longer each time since they trained at a lower intensity.
Stolen notes that this form of training also resulted in several health improvements.But, he emphasizes, the vast majority of improvements were greater with interval training. "For example, we were able to induce cardiac fibrillation in five of eight rats after a period of moderate exercise, and their pumping capacity had only improved half as much as in the interval training group."All plant cells can be made to react by touch or injury. The carnivorous Venus flytrap (Dionaea muscipula) has highly sensitive organs for this purpose.
Sensory hairs that register even the weakest mechanical stimuli, amplify them and convert them into electrical signals that then spread quickly through the plant tissue.Researchers from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, have isolated individual sensory hairs and analysed the gene pool that is active in catching insects. "In the process, we found for the first time the genes that presumably serve throughout the plant kingdom to convert local mechanical stimuli into systemic signals," says JMU plant researcher Professor Rainer Hedrich.That's a fine thing, because virtually nothing was known about mechano-receptors in plants until now. Hedrich's team presents the results in the open-access journal PLOS Biology.Sensory hairs convert touch into electricityThe hinged trap of Dionaea consists of two halves, each carrying three sensory hairs.
When a hair is bent by touch, an electrical signal, an action potential, is generated at its base. At the base of the hair are cells in which ion channels burst open due to a stretching of their envelope membrane and become electrically conductive. The upper part of the sensory hair acts as a lever that amplifies the stimulus triggered by even the lightest prey.These micro-force-touch sensors thus transform the mechanical stimulus into an electrical signal that spreads from the hair over the entire flap trap.
After two action potentials, the trap snaps shut. Based on the number of action potentials triggered by the prey animal during its attempts to free itself, the carnivorous plant estimates whether the prey is big enough -- whether it is worth setting the elaborate digestion in motion.From genes to the function of the touch sensorTo investigate the molecular basis for this unique function, Hedrich's team "harvested" about 1000 sensory hairs. Together with JMU bioinformatician Professor Jörg Schultz, they set out to identify the genes in the hairs."In the process, we noticed that the fingerprint of the genes active in the hair differs from that of the other cell types in the trap," says Schulz.
How is the mechanical stimulus converted into electricity?. "To answer this, we focused on the ion channels that are expressed in the sensory hair or are found exclusively there," says Hedrich.In search of further ion channelsThe sensory hair-specific potassium channel KDM1 stood out. Newly developed electrophysiological methods showed that without this channel, the electrical excitability of the sensory hairs is lost, i.e.
They can no longer fire action potentials. "Now we need to identify and characterise the ion channels that play an important role in the early phases of the action potential," Hedrich said. Story Source.

"If it takes you more than one-and-a-half minutes to ascend four flights of stairs, your health is suboptimal, and it would be a good idea to consult a doctor."This study was conducted to examine the relationship between a daily activity -- i.e.
Climbing stairs -- and the results obtained from exercise testing in a laboratory. "The idea was to find a simple and inexpensive method of assessing heart health," said Dr. Peteiro.
"This can help physicians triage patients for more extensive examinations."The study included 165 symptomatic patients referred for exercise testing because of known or suspected coronary artery disease. Symptoms included chest pain or shortness of breath during exertion. Participants walked or ran on a treadmill, gradually increasing the intensity, and continuing until exhaustion.
Exercise capacity was measured as metabolic equivalents (METs).2 After resting for 15 to 20 minutes, patients were asked to climb four flights of stairs (60 stairs) at a fast pace without stopping, but also without running, and the time was recorded.The researchers analysed the relationship between METs achieved during exercise testing and the time it took to climb four flights of stairs. Patients who climbed the stairs in less than 40-45 seconds achieved more than 9-10 METs. Previous studies have shown that 10 METs during an exercise test is linked with a low mortality rate (1% or less per year, or 10% in 10 years).
In contrast, patients who took 1.5 minutes or longer to climb the stairs achieved less than 8 METs, which translates to a mortality rate of 2-4% per year, or 30% in 10 years.During the treadmill test, the researchers also generated images of the heart to assess its function during exercise -- if the heart works normally during exercise this indicates a low likelihood of coronary artery disease. They then compared these findings to the results of the stair climb. Some 58% of patients who completed the stair climb in more than 1.5 minutes had abnormal heart function during the treadmill examination.
In contrast, just 32% of those who climbed the stairs in less than one minute had abnormal heart function during the treadmill examination.Dr. Peteiro noted that the correlation between the stairs time and exercise capacity (i.e. METs) would be similar in the general population.
But the corresponding mortality rates and heart function by imaging would be more favourable than for patients with symptoms and suspected or confirmed coronary artery disease. Story Source. Materials provided by European Society of Cardiology.

SummaryThis report describes sleep duration and sleep quality among U.S. Nonpregnant women aged 40â59 by menopausal status. Perimenopausal women were most likely to sleep less than 7 hours, on average, in a 24-hour period compared with premenopausal and postmenopausal women.
In contrast, postmenopausal women were most likely to have poor-quality sleep. A greater percentage of postmenopausal women had frequent trouble falling asleep, staying asleep, and not waking well rested compared with premenopausal women. The percentage of perimenopausal women with poor-quality sleep was between the percentages for the other two groups in all three categories. Sleep duration changes with advancing age (4), but sleep duration and quality are also influenced by concurrent changes in womenâs reproductive hormone levels (5). Because sleep is critical for optimal health and well-being (6), the findings in this report highlight areas for further research and targeted health promotion.
DefinitionsMenopausal status. A three-level categorical variable was created from a series of questions that asked women. 1) âHow old were you when your periods or menstrual cycles started?. Â buy generic cipro. 2) âDo you still have periods or menstrual cycles?.
Â. 3) âWhen did you have your last period or menstrual cycle?. Â. And 4) âHave you ever had both ovaries removed, either as part of a hysterectomy or as one or more separate surgeries?. Â Women were postmenopausal if they a) had gone without a menstrual cycle for more than 1 year or b) were in surgical menopause after the removal of their ovaries.
Women were perimenopausal if they a) no longer had a menstrual cycle and b) their last menstrual cycle was 1 year ago or less. Premenopausal women still had a menstrual cycle.Not waking feeling well rested. Determined by respondents who answered 3 days or less on the questionnaire item asking, âIn the past week, on how many days did you wake up feeling well rested?. ÂShort sleep duration. Determined by respondents who answered 6 hours or less on the questionnaire item asking, âOn average, how many hours of sleep do you get in a 24-hour period?.
ÂTrouble falling asleep. Determined by respondents who answered four times or more on the questionnaire item asking, âIn the past week, how many times did you have trouble falling asleep?. ÂTrouble staying asleep. Determined by respondents who answered four times or more on the questionnaire item asking, âIn the past week, how many times did you have trouble staying asleep?. Â Data source and methodsData from the 2015 National Health Interview Survey (NHIS) were used for this analysis.
NHIS is a multipurpose health survey conducted continuously throughout the year by the National Center for Health Statistics. Interviews are conducted in person in respondentsâ homes, but follow-ups to complete interviews may be conducted over the telephone. Data for this analysis came from the Sample Adult core and cancer supplement sections of the 2015 NHIS. For more information about NHIS, including the questionnaire, visit the NHIS website.All analyses used weights to produce national estimates. Estimates on sleep duration and quality in this report are nationally representative of the civilian, noninstitutionalized nonpregnant female population aged 40â59 living in households across the United States.
The sample design is described in more detail elsewhere (7). Point estimates and their estimated variances were calculated using SUDAAN software (8) to account for the complex sample design of NHIS. Linear and quadratic trend tests of the estimated proportions across menopausal status were tested in SUDAAN via PROC DESCRIPT using the POLY option. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

NCHS Data generic cipro online for sale Brief No. 286, September 2017PDF Versionpdf icon (374 KB)Anjel Vahratian, Ph.D.Key findingsData from the National Health Interview Survey, 2015Among those aged 40â59, perimenopausal women (56.0%) were more likely than postmenopausal (40.5%) and premenopausal (32.5%) women to sleep less than 7 hours, on average, in a 24-hour period.Postmenopausal women aged 40â59 were more likely than premenopausal women aged 40â59 to have trouble falling asleep (27.1% compared with 16.8%, respectively), and staying asleep (35.9% compared with 23.7%), four times or more in the past week.Postmenopausal women aged 40â59 (55.1%) were more likely than premenopausal women aged 40â59 (47.0%) to not wake up feeling well rested 4 days or more in the past week.Sleep duration and quality are important contributors to health and wellness. Insufficient sleep is associated with generic cipro online for sale an increased risk for chronic conditions such as cardiovascular disease (1) and diabetes (2). Women may be particularly vulnerable to sleep problems during times of reproductive hormonal change, such as after the menopausal transition.
Menopause is âthe permanent cessation of menstruation generic cipro online for sale that occurs after the loss of ovarian activityâ (3). This data brief describes sleep duration and sleep quality among nonpregnant women aged 40â59 by menopausal status. The age range selected for this analysis reflects the focus on midlife sleep health. In this analysis, 74.2% of women are premenopausal, 3.7% are perimenopausal, and 22.1% generic cipro online for sale are postmenopausal.

NCHS, National Health Interview Survey, 2015. SummaryThis report describes sleep duration and sleep quality among U.S. Nonpregnant women aged 40â59 by menopausal status. Perimenopausal women were most likely to sleep less than 7 hours, on average, in a 24-hour period compared with premenopausal and postmenopausal women.
In contrast, postmenopausal women were most likely to have poor-quality sleep. A greater percentage of postmenopausal women had frequent trouble falling asleep, staying asleep, and not waking well rested compared with premenopausal women. The percentage of perimenopausal women with poor-quality sleep was between the percentages for the other two groups in all three categories. Sleep duration changes with advancing age (4), but sleep duration and quality are also influenced by concurrent changes in womenâs reproductive hormone levels (5).
Because sleep is critical for optimal health and well-being (6), the findings in this report highlight areas for further research and targeted health promotion. DefinitionsMenopausal status. A three-level categorical variable was created from a series of questions that asked women. 1) âHow old were you when your periods or menstrual cycles started?.
Â. 2) âDo you still have periods or menstrual cycles?. Â. 3) âWhen did you have your last period or menstrual cycle?.
Â. And 4) âHave you ever had both ovaries removed, either as part of a hysterectomy or as one or more separate surgeries?. Â Women were postmenopausal if they a) had gone without a menstrual cycle for more than 1 year or b) were in surgical menopause after the removal of their ovaries. Women were perimenopausal if they a) no longer had a menstrual cycle and b) their last menstrual cycle was 1 year ago or less.
Premenopausal women still had a menstrual cycle.Not waking feeling well rested. Determined by respondents who answered 3 days or less on the questionnaire item asking, âIn the past week, on how many days did you wake up feeling well rested?. ÂShort sleep duration. Determined by respondents who answered 6 hours or less on the questionnaire item asking, âOn average, how many hours of sleep do you get in a 24-hour period?.
ÂTrouble falling asleep. Determined by respondents who answered four times or more on the questionnaire item asking, âIn the past week, how many times did you have trouble falling asleep?. ÂTrouble staying asleep. Determined by respondents who answered four times or more on the questionnaire item asking, âIn the past week, how many times did you have trouble staying asleep?.
 Data source and methodsData from the 2015 National Health Interview Survey (NHIS) were used for this analysis. NHIS is a multipurpose health survey conducted continuously throughout the year by the National Center for Health Statistics. Interviews are conducted in person in respondentsâ homes, but follow-ups to complete interviews may be conducted over the telephone. Data for this analysis came from the Sample Adult core and cancer supplement sections of the 2015 NHIS.
For more information about NHIS, including the questionnaire, visit the NHIS website.All analyses used weights to produce national estimates. Estimates on sleep duration and quality in this report are nationally representative of the civilian, noninstitutionalized nonpregnant female population aged 40â59 living in households across the United States. The sample design is described in more detail elsewhere (7). Point estimates and their estimated variances were calculated using SUDAAN software (8) to account for the complex sample design of NHIS.
Linear and quadratic trend tests of the estimated proportions across menopausal status were tested in SUDAAN via PROC DESCRIPT using the POLY option. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

IStock Share Fast Facts New @HopkinsMedicine study finds African-American women with common form of hair loss at increased risk of uterine fibroids - Click to Tweet New study in @JAMADerm shows most common form of alopecia (hair loss) in African-American women associated with higher risks of uterine fibroids - Click to Tweet In a study of medical records gathered on hundreds of thousands of African-American women, Johns Hopkins researchers say they have evidence that women with a common form of hair loss have an increased chance of developing uterine leiomyomas, or fibroids.In a report on the research, published in the December 27 issue of JAMA Dermatology, the researchers call on physicians who treat women with central centrifugal cicatricial alopecia (CCCA) to make patients aware that they may be at increased risk for fibroids and should be screened for the condition, particularly if they have symptoms such as heavy bleeding and pain. CCCA predominantly affects black women and is the most common form of permanent alopecia in this population. The excess scar tissue that forms as a result of this type of hair loss may also explain the higher risk for uterine fibroids, which are characterized by fibrous growths in the lining of the womb. Crystal Aguh, M.D., assistant professor of dermatology at the Johns Hopkins University School of Medicine, says the scarring associated with CCCA is similar to the scarring associated with excess fibrous tissue elsewhere in the body, a situation that may explain why women with this type of hair loss are at a higher risk for fibroids.People of African descent, she notes, are more prone to develop other disorders of abnormal scarring, termed fibroproliferative disorders, such as keloids (a type of raised scar after trauma), scleroderma (an autoimmune disorder marked by thickening of the skin as well as internal organs), some types of lupus and clogged arteries.
During a four-year period from 2013-2017, the researchers analyzed patient data from the Johns Hopkins electronic medical record system (Epic) of 487,104 black women ages 18 and over. The prevalence of those with fibroids was compared in patients with and without CCCA. Overall, the researchers found that 13.9 percent of women with CCCA also had a history of uterine fibroids compared to only 3.3 percent of black women without the condition. In absolute numbers, out of the 486,000 women who were reviewed, 16,212 had fibroids.Within that population, 447 had CCCA, of which 62 had fibroids. The findings translate to a fivefold increased risk of uterine fibroids in women with CCCA, compared to age, sex and race matched controls.
Aguh cautions that their study does not suggest any cause and effect relationship, or prove a common cause for both conditions. ÂThe cause of the link between the two conditions remains unclear,â she says. However, the association was strong enough, she adds, to recommend that physicians and patients be made aware of it. Women with this type of scarring alopecia should be screened not only for fibroids, but also for other disorders associated with excess fibrous tissue, Aguh says. An estimated 70 percent of white women and between 80 and 90 percent of African-American women will develop fibroids by age 50, according to the NIH, and while CCCA is likely underdiagnosed, some estimates report a prevalence of rates as high as 17 percent of black women having this condition.

- Click to Tweet The âmutational burden,â or the number of mutations present in a tumorâs DNA, is a good predictor of whether that cancer type will respond to a class of cancer immunotherapy drugs known as checkpoint inhibitors, a new study led by Johns Hopkins Kimmel Cancer Center researchers shows. The finding, published in the Dec. 21 New England Journal of Medicine, could be used to guide future clinical trials for these drugs. Checkpoint inhibitors are a relatively new class of drug that helps the immune system recognize cancer by interfering with mechanisms cancer cells use to hide from immune cells. As a result, the drugs cause the immune system to fight cancer in the same way that it would fight an .
These medicines have had remarkable success in treating some types of cancers that historically have had poor prognoses, such as advanced melanoma and lung cancer. However, these therapies have had little effect on other deadly cancer types, such as pancreatic cancer and glioblastoma. The mutational burden of certain tumor types has previously been proposed as an explanation for why certain cancers respond better than others to immune checkpoint inhibitors says study leader Mark Yarchoan, M.D., chief medical oncology fellow. Work by Dung Le, M.D., associate professor of oncology, and other researchers at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Cancer Institute for Cancer Immunotherapy showed that colon cancers that carry a high number of mutations are more likely to respond to checkpoint inhibitors than those that have fewer mutations. However, exactly how big an effect the mutational burden has on outcomes to immune checkpoint inhibitors across many different cancer types was unclear.
To investigate this question, Yarchoan and colleagues Alexander Hopkins, Ph.D., research fellow, and Elizabeth Jaffee, M.D., co-director of the Skip Viragh Center for Pancreas Cancer Clinical Research and Patient Care and associate director of the Bloomberg~Kimmel Institute, combed the medical literature for the results of clinical trials using checkpoint inhibitors on various different types of cancer. They combined these findings with data on the mutational burden of thousands of tumor samples from patients with different tumor types. Analyzing 27 different cancer types for which both pieces of information were available, the researchers found a strong correlation. The higher a cancer typeâs mutational burden tends to be, the more likely it is to respond to checkpoint inhibitors. More than half of the differences in how well cancers responded to immune checkpoint inhibitors could be explained by the mutational burden of that cancer.
ÂThe idea that a tumor type with more mutations might be easier to treat than one with fewer sounds a little counterintuitive. Itâs one of those things that doesnât sound right when you hear it,â says Hopkins. ÂBut with immunotherapy, the more mutations you have, the more chances the immune system has to recognize the tumor.â Although this finding held true for the vast majority of cancer types they studied, there were some outliers in their analysis, says Yarchoan. For example, Merkel cell cancer, a rare and highly aggressive skin cancer, tends to have a moderate number of mutations yet responds extremely well to checkpoint inhibitors. However, he explains, this cancer type is often caused by a cipro, which seems to encourage a strong immune response despite the cancerâs lower mutational burden.
In contrast, the most common type of colorectal cancer has moderate mutational burden, yet responds poorly to checkpoint inhibitors for reasons that are still unclear. Yarchoan notes that these findings could help guide clinical trials to test checkpoint inhibitors on cancer types for which these drugs havenât yet been tried. Future studies might also focus on finding ways to prompt cancers with low mutational burdens to behave like those with higher mutational burdens so that they will respond better to these therapies. He and his colleagues plan to extend this line of research by investigating whether mutational burden might be a good predictor of whether cancers in individual patients might respond well to this class of immunotherapy drugs. ÂThe end goal is precision medicineâmoving beyond whatâs true for big groups of patients to see whether we can use this information to help any given patient,â he says.
Yarchoan receives funding from the Norman &. Ruth Rales Foundation and the Conquer Cancer Foundation. Through a licensing agreement with Aduro Biotech, Jaffee has the potential to receive royalties in the future..

As a result, the drugs cause the immune system to fight cancer in the same way that it would fight an .
These medicines have had remarkable success in treating some types of cancers that historically have had poor prognoses, generic cipro online for sale such as advanced melanoma and lung cancer. However, these therapies have had little effect on other deadly cancer types, such as pancreatic cancer and glioblastoma. The mutational burden of certain tumor types has previously been proposed as an explanation for why certain cancers respond better than others generic cipro online for sale to immune checkpoint inhibitors says study leader Mark Yarchoan, M.D., chief medical oncology fellow. Work by Dung Le, M.D., associate professor of oncology, and other researchers at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Cancer Institute for Cancer Immunotherapy showed that colon cancers that carry a high number of mutations are more likely to respond to checkpoint inhibitors than those that have fewer mutations. However, exactly how big an effect the mutational burden has on outcomes to immune checkpoint inhibitors across generic cipro online for sale many different cancer types was unclear.
To investigate this question, Yarchoan and colleagues Alexander Hopkins, Ph.D., research fellow, and Elizabeth Jaffee, M.D., co-director of the Skip Viragh Center for Pancreas Cancer Clinical Research and Patient Care and associate director of the Bloomberg~Kimmel Institute, combed the medical literature for the results of clinical trials using checkpoint inhibitors on various different types of cancer. They combined these findings with data on the mutational burden of thousands of tumor samples from patients with different tumor types generic cipro online for sale. Analyzing 27 different cancer types for which both pieces of information were available, the researchers found a strong correlation. The higher a cancer typeâs mutational burden tends to be, the more likely it is to respond to checkpoint inhibitors. More than half of the differences in how well cancers responded to immune checkpoint generic cipro online for sale inhibitors could be explained by the mutational burden of that cancer.
ÂThe idea that a tumor type with more mutations might be easier to treat than one with fewer sounds a little counterintuitive. Itâs one of those things that doesnât sound right when you generic cipro online for sale hear it,â says Hopkins. ÂBut with immunotherapy, the more mutations you have, the more chances the immune system has to recognize the tumor.â Although this finding held true for the vast majority of cancer types they studied, there were some outliers in their analysis, says Yarchoan. For example, Merkel cell cancer, a rare and highly aggressive skin generic cipro online for sale cancer, tends to have a moderate number of mutations yet responds extremely well to checkpoint inhibitors. However, he explains, this cancer type is often caused by a cipro, which seems to encourage a strong immune response despite the cancerâs lower mutational burden.
In contrast, the most common type of colorectal cancer has moderate mutational burden, yet responds poorly to checkpoint inhibitors for reasons that are still unclear. Yarchoan notes that these findings could help guide clinical trials to test checkpoint inhibitors on cancer types for which these drugs havenât yet been tried generic cipro online for sale. Future studies might also focus on finding ways to prompt cancers with low mutational burdens to behave like those with higher mutational burdens so that they will respond better to these therapies. He and his colleagues plan to extend this line of research by investigating whether mutational burden might be a generic cipro online for sale good predictor of whether cancers in individual patients might respond well to this class of immunotherapy drugs. ÂThe end goal is precision medicineâmoving beyond whatâs true for big groups of patients to see whether we can use this information to help any given patient,â he says.
