Comparison of immune response to 1918 and H5N1 influeza viruses shows similarities
A comparison of the 1918 Spanish influenza and the H5N1 avian influenza viruses suggests that while the two viruses appear to trigger a similar abnormal immune response in animal models, there are distinct differences. view more (2007-03-01)
Respiratory rhythms can help predict insomnia
The breathing and heart rates and cortisol levels of women with metastatic breast cancer can be used to predict if they'll suffer from chronic insomnia and sleep disruptions, a common complaint from patients who want to maintain their quality of life. view more (2008-10-21)
Artificial light at night stimulates breast cancer growth in laboratory mice
Results from a new study in laboratory mice show that nighttime exposure to artificial light stimulated the growth of human breast tumors by suppressing the levels of a key hormone called melatonin. view more (2005-12-20)
The Jetlag of a Glowing Fish and More: Press Release from PLoS Biology
What Does an Airline Traveler Have in Common with a Glowing Fish? In William Gibson's novel Pattern Recognition, the protagonist posits a theory of jet lag: "Souls can't move that quickly, and are left behind, and must be awaited, upon arrival, like lost luggage." Science has yet to address the issue of a spiritual speed limit,... view more... (2005-01-25)
Social life-history response to individual immune challenge of workers of Bombus terrestris: a possible new cooperative phenomenon
Solitary organisms can minimise fitness loss from parasitism with a facultative change to an earlier reproduction. Such a shift of the reproductive effort gives the host a chance to compensate for the cost on future reproduction resulting from the infection. In the case of social insects, where brood care and reproductive effort are shared between... view more... (2004-02-05)
Press release from Nature and the Nature Research Journals dated 7 September
NATURE (http://www.nature.com/nature) [1] Uric acid signals danger DOI: 10.1038/nature01991 (http://dx.doi.org/10.1038/nature01991) Uric acid may signal the immune system to warn it of impending danger, according to a paper published online by Nature this week. The research provides a molecular link between cell injury and immunity, and may have... view more... (2003-09-08)
Halting histamine action means hallelujah for hay fever sufferers
In allergic diseases such as asthma, hay fever, and rhinitis an allergen stimulates the release of antibodies that attach themselves to mast cells causing these cells to release histamine, which can cause symptoms like itching of the nose, skin and eyes, sneezing, and wheezing. view more (2006-05-05)
The first autism disease genes
The autistic disorder, a neurodevelopmental disease first described in 1943, represents a challenge for treatment and a puzzle for research. Alongside Asperger syndrome, a milder form of the disorder, autism is classified in the continuum of various Autism Spectrum Disorders (ASD), all of which are characterized by deficits in language, social... view more...

How Toxoplasma gondii gets noticed
Researchers provide insight into how Toxoplasma gondii, a common parasite of people and other animals, triggers an immune response in its host. view more (2009-01-20)
YouTube videos yield clues to brain injury symptom
Brain injury researchers at the University of Kentucky have spent hundreds of hours watching YouTube videos of people getting smacked, punched and knocked in the head during sporting events and recreational activities. But those researchers weren't goofing off on the Internet; they were doing hard science. view more (2009-09-03)
Aid and health experts call for Government to support humanitarian capacity to respond to weapons of mass destruction
The London School of Hygiene and Tropical Medicine and Merlin, the charity that provides healthcare for people in crises, have completed a study of the potential humanitarian response to the use of weapons of mass destruction (WMD). In the detailed paper we call for the Government to support an independent group of NGOs to prepare for a response... view more... (2003-01-09)
Pain and stiffness intensity ebb and flow according to body clock in osteoarthritic patients
Levels of pain intensity and arthritic stiffness closely follow the rhythms of the body clock, reveals research in the Annals of the Rheumatic Diseases. view more (2002-11-12)
Increase in childhood leukaemia may be part due to increased light at night
London, UK: International experts will (Wednesday 8 September) consider the evidence for a link between the rise in childhood leukaemia and increased light at night at an international scientific conference in London. The incidence of childhood leukaemia increased dramatically in the twentieth century. The increase has mainly affected the under... view more... (2004-09-06)
If You Are Down, You May Be More Likely To Get Infections
The association between depression and immune response is not yet clear. The biological mechanisms by which depression alters the immune system is not yet understood. The purpose of this study was to investigate the longitudinal relationship between depressive symptoms and cellular immune response. A cohort study with a baseline measurement and... view more...

Strong associations between disturbed rest/activity rhythms and mortality rates in older men
A research abstract that will be presented on Wednesday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS), is the first to report strong associations between disturbed rest/activity rhythms and mortality rates in older, community-dwelling (non-institutionalized) men. view more (2008-06-11)
Healthcare staff not prepared for flu pandemic
Nearly half of health workers surveyed would not go to work during an influenza pandemic. The results of a survey of health workers in Maryland, USA, published today in the open access journal BMC Public Health reveal that the staff's perceived importance of their role in the response to a pandemic is the most important factor influencing... view more...

Individuals vary their immune response according to age, sex and the costs
Is it always good to respond maximally when pathogens or disease strike, or should individuals vary their immune response to balance immediate and future costs? view more (2008-09-11)
Chronic fatigue syndrome impairs a person's slow wave activity during sleep
Chronic fatigue syndrome (CFS) has been associated with altered amounts of slow wave sleep, which could reflect reduced electroencephalograph (EEG) activity and impaired sleep regulation. view more (2007-05-01)
Melatonin Most Effective For Sleep When Taken For Off-Hour Sleeping
Researchers from the Divisions of Sleep Medicine at Brigham and Women's Hospital and Harvard Medical School have found in a double-blind placebo-controlled clinical study, that melatonin, taken orally during non-typical sleep times, significantly improves an individual's ability to sleep. view more (2006-05-01)
How to increase the chances of remaining virus free Pakistani patients with HCV?
