The study found that both interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) levels varied with sleep duration in women following multiple adjustments for a number of confounding factors.

The hormone aldosterone regulates levels of sodium in the blood and thereby helps control blood pressure.

Results indicate that the odds ratio for prevalent stroke was 1.65 [CI: 1.

Research by the University of Warwick and University College London has found that levels of inflammatory markers vary significantly with sleep duration in women, but not men.

(Nasdaq: CEPH) announced that it has submitted a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) requesting approval of NUVIGIL(R) (armodafinil) Tablets [C-IV] for the indication of improved wakefulness in patients with excessive sleepiness associated with jet lag disorder resulting from eastbound travel.

Many often don't remember doing any of these activities the next morning. Similarly, this drug has been shown to awaken the minimally conscious into a conscious state. A new study by Georgetown University Medical Center (GUMC) researchers may help explain why these "awakenings" occur.

(NASDAQ: MYL) announced that its subsidiary Mylan Pharmaceuticals Inc. has received approval from the U.S. Food and Drug Administration (FDA) for its supplemental Abbreviated New Drug Application (ANDA) for Temazepam Capsules USP, 22.5 mg. This strength is in addition to Mylan's currently marketed 15 mg and 30 mg strengths of the product. Temazepam Capsules are the generic version of Mallinckrodt's Restoril®, a sleep aid, which had total U.S. Sleep / Sleep Disorders / Insomnia Fri, 26 Jun 2009 02:00:00 PDT http://www.medicalnewstoday.com/articles/155426.php http://www.medicalnewstoday.com/articles/155426.php Stroke patients with obstructive sleep apnea (OSA) who undergo treatment with continuous positive airway pressure (CPAP) following their stroke may substantially reduce their risk of death, according to Spanish research to be published in the July 1 issue of the American Journal of Respiratory and Critical Care Medicine. Stroke Fri, 26 Jun 2009 00:00:00 PDT http://www.medicalnewstoday.com/articles/155351.php http://www.medicalnewstoday.com/articles/155351.php New imaging research in the June 24 issue of The Journal of Neuroscience helps explain why sleep deprivation affects some people more than others. After staying awake all night, those who are genetically vulnerable to sleep loss showed reduced brain activity, while those who are genetically resilient showed expanded brain activity, the study found. The findings help explain individual differences in the ability to compensate for lack of sleep.

It is a fatal disease with few treatment options. According to an article in this week's issue of The Lancet, Nifurtimox in combination with eflornithine is safe, effective, and more affordable than current treatments for sleeping sickness. This new drug combination should be implemented as a matter of priority by control programmes across sub-Saharan Africa.

Now, researchers at the RIKEN-MIT Center for Neural Circuit Genetics of MIT's Picower Institute for Learning and Memory have shown that mice prevented from "replaying" their waking experiences while asleep do not remember them as well as mice who are able to perform this function.

The research in the renowned Department of Genetics at the University of Leicester is being carried out by Ms Mobina Khericha and Dr Eran Tauber. It represents a new approach to study the genetics of sleep. Using fruitflies as models the researchers aim at understanding the genetics of sleep and identifying genes involved in this process.

Neuroscientists in the Faculty of Physical Education and Recreation looked at two groups of people: those who wake up early and feel most productive in the morning, and those who were identified as evening people, those who typically felt livelier at night.

People with narcolepsy may feel an overwhelming urge to sleep at various points in the day, and they will often fall asleep spontaneously for a few seconds to a few minutes.

An international team of scientists, including Patrice Bourgin from CNRS 'Institut des neurosciences cellulaires et intégratives' in Strasbourg, has just published a detailed study in PlosBiology on the role of melanopsin, a molecule involved in mediating the effects of light on sleep.

In addition, different types of breathing problems appear more closely associated with different categories of arrhythmia.

In this same study, CX717 demonstrated equal efficacy with the opioid antagonist Naloxone, a drug used to counter the effects of opioids on suppression of breathing.

Terry McKinnes, 54, of Falkirk, is one of the unfortunate people who suffers from idiopathic insomnia who feels she has spent almost her entire life awake.

Results indicate that the adjusted odds ratio for type 2 diabetes was 2.

These data have not been evaluated by the FDA or other regulatory authorities for use of sodium oxybate in the treatment of fibromyalgia.

Cerebral hypothermia, or cooling of the brain, has been found to reduce cerebral metabolism in other medical conditions, but its effects in insomnia are unknown.
