Music Composition from the Brain Signal: Representing the Mental State by Music
This paper proposes a method to translate human EEG into music, so as to represent mental state by music. The arousal levels of the brain mental state and music emotion are implicitly used as the bridge between the mind world and the music. The arousal level of the brain is based on the EEG features extracted mainly by wavelet analysis, and the music arousal level is related to the musical parameters such as pitch, tempo, rhythm, and tonality. While composing, some music principles (harmonics and structure) were taken into consideration. With EEGs during various sleep stages as an example, the music generated from them had different patterns of pitch, rhythm, and tonality. 35 volunteers listened to the music pieces, and significant difference in music arousal levels was found. It implied t...MedWorm Message: Get the very latest Swine Flu news via the MedWorm Swine Flu RSS news feed - updated hourly from thousands of authoritative health and news sources.

The Dangers Of Daylight Savings Time
Daylight Savings Time can be hazardous for your health. On average, people go to work or school on the first Monday of Daylight Savings after sleeping 40 fewer minutes than normal. And recent studies have found there's a higher risk of heart attacks, traffic accidents and workplace injuries on the first Monday of Daylight Savings. "Many people already are chronically sleep-deprived, and Daylight Savings Time can make them even more tired for a few days," said Dr. Nidhi Undevia, medical director of the Sleep Program at Loyola University Health System...

Daylight-Saving Time Switch May Leave You Sleepy, Physician Says
Many Americans will lose an hour of sleep on March 14, the first day of daylight-saving time, when clocks are set ahead one hour at 2 a.m. local standard time-making it harder to wake up, causing difficulty in staying alert and increasing the chance of sleepy-driving car crashes. Ronald D. Chervin, M.D., says Americans can prepare for the daylight-saving time switch. Chervin says it can be as simple as going to sleep and waking up earlier by 15 minute intervals in the days leading up to Sunday's change... (Source: Health News from Medical News Today)

More than two species lost every year
This report is not all doom and gloom, but we're losing species at an alarming rate and many of our species are seriously threatened," he said. "These species could the tip of the iceberg unless we take action."Matt Shardlow, head of Buglife, said: "The report [confirms] we are in the midst of an extinction crisis and it is happening here in England under our very noses."Dozens of scientists trawled records going back to the first century AD from official lists and books. They identified 492 species recorded in England that could no longer be found, all but 12 of which disappeared after 1800.A further 943 species are listed under the UK's Biodiversity Action Plan (BAP) as plants and animals under threat. These include a number of species now extinct in many counties or regions of England. ...

Down-regulation of hypoxia inducible factor-1α: a possible explanation for the protective effects of estrogen on genioglossus fatigue resistance
We examined the effects of estrogen on the contractility of the genioglossus by exposing rats to alternating cycles of 6[ndash]8% O2 every 15 s for a total duration of 35 d. The results showed that muscle fatigue resistance was significantly decreased after CIH but was partially reversed after estrogen treatment. Compared with the control group, real-time reverse transcription[ndash]polymerase chain reaction and western blotting showed higher levels of HIF-1[alpha] messenger RNA and protein in the CIH group, but estrogen treatment reduced, in a dose-independent manner, the levels of HIF-1[alpha] messenger RNA and protein in rats exposed to CIH. We conclude that CIH induced the expression of HIF-1[alpha] in the genioglossus and altered the physical properties towards a more fatigable phenot...

Restless legs syndrome and pregnancy in Kayseri, Turkey: A hospital based survey
The prevalence of restless legs syndrome (RLS) is low in the general population in Turkey. To assess the prevalence of RLS in pregnancy, a hospital-based survey assessing symptoms of RLS and other sleep problems was performed through face-to-face interviews and physical examination on 983 pregnant women from 11 hospitals in the two urban and four suburban areas of Kayseri, Turkey, at the time of delivery and 6 months after delivery. RLS is diagnosed clinically by means of the four essential criteria of the International RLS Study Group. A total of 103 women reported the occurrence of RLS symptoms during pregnancy, giving an RLS prevalence rate of 10.48%, with presence of symptoms more than three times per month, which decreased to 2.9% after 6 months. A significant relationship was observe...

The early postoperative course of surgical sleep apnea patients
Recent guidelines from the American Society of Anesthesiologists recommended postoperative monitoring for most patients undergoing surgery for obstructive sleep apnea (OSA). These guidelines, however, are largely based on retrospective literature and expert opinion. The appropriate level of postoperative monitoring remains controversial. Our objective was to prospectively document the early postoperative course of patients undergoing OSA surgery.Prospective cohort study.One hundred twenty-one patients (age 43.9 ± 13.5 years, 79.8% male) with sleep-study proven OSA (apnea-hypopnea index 31.9 ± 22.7) who were undergoing surgery for OSA at our tertiary care center were recruited from 2007 to 2009. Outcome measures were: 1) incidence of respiratory complications requiring nursing interventio...

That Midday Nap May Make You Smarter
Before you dismiss a midday nap as a sign of laziness, you may want to learn about a recent study suggesting that it may be just the thing to make you smarter.
The study done at the University of California shows that an hour's nap can boost your brain power. In the study, healthy young adults who were allowed to sleep for 90 minutes midday actually performed better than those who did not. Their performance also improved from their baseline testing, suggesting that they also got smarter.
As we spend time awake for a prolonged period of time, we have more difficulty learning new information. It is thought that sleep is needed to clear our short-term memory storage in an area of the brain called the hippocampus to make room for new information. This transfer of information is thought to oc...MedWorm Message: Get the very latest Swine Flu news via the MedWorm Swine Flu RSS news feed - updated hourly from thousands of authoritative health and news sources.

Dentofacial characteristics as indicator of obstructive sleep apnoea-hypopnoea syndrome in patients with severe obesity
Obstructive sleep apnoea-hypopnoea syndrome (OSAHS) is a complex disease with a multifactor aetiology. OSAHS is strongly associated with obesity, but there are many other clinical risk factors, such as the dentofacial characteristics of hard and soft tissues, hyoid bone position, neck circumference, upper airway spaces and nasal respiration. A descriptive cross-sectional study was carried out involving 13 patients (one man and 12 women) with severe obesity in order to evaluate specific physical dentofacial characteristics through a cephalometric examination. Cephalometry was analysed using 29 measurements of the hard and soft tissues of the craniofacial structures and dimensions of the upper airways. The demographic data revealed a mean body mass index of 48 ± 6.26 kg m[minus]2 and cervic...MedWorm Message: Get the very latest Swine Flu news via the MedWorm Swine Flu RSS news feed - updated hourly from thousands of authoritative health and news sources.

Usp46, encoding a ubiquitin specific peptidase, is a quantitative trait gene underlying "behavioral despair" in mice
CS mice exhibit several distinct phenotypes of circadian behavioral rhythms and sleep properties. Because many mental illnesses are associated with abnormalities in the circadian rhythms and sleep pattern, we characterized the behavioral phenotypes in CS mice with a battery of behavioral tests. Among these phenotypes, we found that CS mice exhibit an extremely low immobility time in both the tail suspension test (TST) and forced swimming test (FST). To uncover the genetic basis for lower immobility time, we first performed quantitative trait locus (QTL) mapping using CS and C57BL/6J mice, which revealed significant QTLs on chromosomes (Chrs) 4 (FST) and 5 (TST and FST). To identify the quantitative trait gene on Chr 5, we narrowed the QTL interval to 0.5 Mb using several congenic and subco...

Anaesthesia with a combination of ketamine and medetomidine in the rabbit: effect of premedication with buprenorphine
Conclusion and clinical relevance Premedication with buprenorphine significantly increased the duration of anaesthesia induced by K/M, with no significant depression of respiration further to the control treatment within the first 10 minutes of anaesthesia. The MAP decreased but this was not reflected in a difference in other physiological parameters. These data show that premedication with buprenorphine, before K/M anaesthesia in the rabbit, has few negative effects and may provide beneficial analgesia.

Thinking beyond the bladder: antidiuretic treatment of nocturia
Nocturia is a bothersome and highly prevalent urological condition characterised by the need to wake to void at night. Contrary to popular misconception, nocturia is equally common in men and women, and although its prevalence increases with age, a significant proportion of younger people are also affected. Nocturia leads to repeated fragmentation of sleep and consequently to a serious decline in daytime functioning and in overall quality of life and health. As such, its impact should not be underestimated by clinicians. Traditionally, nocturia has been regarded as a symptom of benign prostatic enlargement and/or overactive bladder syndrome, with treatment therefore directed towards increasing the capacity of the bladder to hold urine. Such treatments have proven largely ineffective in man...

Shift-work research: Where do we stand, where should we go?
Shift-work seriously affects the health and well-being of millions of people worldwide, and the number of shift workers is constantly rising (currently approximately 20% of the workforce). While some effects are acute, others lead to chronic syndromes that persist after retirement. Though health problems in shift workers are well established, we still do not properly understand the causal mechanisms underlying shift-work's effects on health. One reason may be the heterogeneity in shift-work research design and methodology, rendering comparison between studies difficult or even impossible. Shift-work also involves a multitude of interacting factors, and we do not yet fully understand many of these interactions. Interindividual differences between workers are central predictors for health. A...

An Official ATS Clinical Policy Statement: Congenital Central Hypoventilation Syndrome: Genetic Basis, Diagnosis, and Management.
Conclusions: A PHOX2B mutation is required to confirm the diagnosis of CCHS. Knowledge of the specific PHOX2B mutation aids in anticipating the CCHS phenotype severity. Parents of patients with CCHS should be tested for PHOX2B mutations. Maintaining a high index of suspicion in cases of unexplained alveolar hypoventilation will likely identify a higher incidence of milder cases of CCHS. Recommended management options aimed toward maximizing safety and optimizing neurocognitive outcome include: (1) biannual then annual in-hospital comprehensive evaluation with (i) physiologic studies during awake and asleep states to assess ventilatory needs during varying levels of activity and concentration, in all stages of sleep, with spontaneous breathing, and with artificial ventilation, and to assess...
