Sleep deprivation a factor in weight gain

The new research by scientists at the University of South Australia has revealed that though their appetites had decreased the study participants gained weight when their sleep was restricted.

Research identifies 3D structure of key nuclear pore building block

The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.

Discovery 'significant step' in understanding leukaemia drug resistance

Scientists have pinpointed an enzyme responsible for breaking down and inactivating a key childhood leukaemia drug, which could help to explain why around 20 per cent of patients do not respond to therapy. Their findings are published in the Journal of Clinical Investigation.

WHO recommends global use of rotavirus vaccines - can protect millions of children from diarrhoeal diseaseas

The World Health Organization (WHO) has recommended that rotavirus vaccination be included in all national immunization programmes to provide protection against a virus that is responsible for more than 500,000 diarrhoeal deaths and 2 million hospitalizations every year among children. More than 85% of these deaths occur in developing countries in Africa and Asia. This new policy will help ensure access to rotavirus vaccines in the world's poorest countries.

Cancer vaccine efficacy enhanced using anti-diabetic drug Metformin

After a vaccination or an infection, the human immune system remembers to keep protecting against invaders it has already encountered, with the aid of specialized B-cells and T-cells. Immunological memory has long been the subject of intense study, but the underlying cellular mechanisms regulating the generation and persistence of long-lived memory T cells remain largely undefined. Now, University of Pennsylvania School of Medicine researchers have found that a common anti-diabetic drug might enhance the effectiveness of vaccines. The findings are described this week in an advanced online publication of Nature.

Discovery of new genetic immune disorder in children

Your immune system plays an important function in your health - it protects you against viruses, bacteria, and other toxins that can cause disease. In autoinflammatory diseases, however, the immune system goes awry, causing unprovoked and dangerous inflammation.

Diabetic medication 'glibenclamide' may prevent nicotine-induced SIDS

According to researchers at McMaster University, exposure of the fetus to nicotine results in the inability to respond to decreases in oxygen - known as hypoxia - which may result in a higher incidence of SIDS.

Metformin may 'revolutionize' cancer-fighting treatments

Researchers at McGill University and the University of Pennsylvania have discovered that a widely used anti-diabetic drug can boost the immune system and increase the potency of vaccines and cancer treatments. Their findings will be published June 3 in the journal Nature.

A bionic broadband ear

MIT engineers have built a fast, ultra-broadband, low-power radio chip, modeled on the human inner ear, that could enable wireless devices capable of receiving cell phone, Internet, radio and television signals.

Women with heavy periods may have an undiagnosed bleeding disorder

According to researchers in the United States many women suffer from bleeding disorders, but are unaware they have one because doctors are not looking for the condition.

Discovery of new arenavirus associated with hemorrhagic fever – first identified in nearly four decades

Scientists at Columbia University's Mailman School of Public Health, the South African National Institute for Communicable Diseases of National Health Laboratory Service (NICD-NHLS), the U.S. Centers for Disease Control and Prevention, and Roche's 454 Life Sciences Corporation have discovered the new virus responsible for a highly fatal hemorrhagic fever outbreak in Zambia and South Africa in late 2008.

Scientists create pig stem cells

Scientists have managed to induce cells from pigs to transform into pluripotent stem cells - cells that, like embryonic stem cells, are capable of developing into any type of cell in the body. It is the first time in the world that this has been achieved using somatic cells (cells that are not sperm or egg cells) from any animal with hooves (known as ungulates).

Report identifies early childhood conditions that lead to adult health disparities

The origins of many adult diseases can be traced to early negative experiences associated with social class and other markers of disadvantage.

Greater understanding on leptin's role in brain neurocircuitry

In investigating the complex neurocircuitry behind weight gain and glucose control, scientists have known that the hormone leptin plays a key role in the process. But within the myriad twists and turns of the brain's intricate landscape, the exact pathways that the hormone travels to exert its influence have remained a mystery.

Bleeding disorders going undiagnosed; new guidelines to help

Nearly one percent of the population suffers from bleeding disorders, yet many women don't know they have one because doctors aren't looking for the condition, according to researchers at Duke University Medical Center.

Impact of Medicare Part D on access to and cost sharing for specialty biologic medications for beneficiaries with rheumatoid arthritis

Biologic disease-modifying antirheumatic drugs (DMARDs) such as adalimumab, etanercept and infliximab are effective at reducing symptoms and slowing progression of rheumatoid arthritis (RA). These drugs act more quickly, require less laboratory monitoring, and are better tolerated than nonbiologic DMARDs, but they are also up to 100 times more expensive.

New method to induce protein folding

A new method to induce protein folding by taking the pressure off of proteins is up to 100 times faster than previous methods, and could help guide more accurate computer simulations for how complex proteins fold, according to research by a team of University of Illinois scientists accepted for publication in the journal Nature Methods and posted on the journal's Web site May 31.

Oligophrenin-1 signaling protein linked to mental retardation controls synapse maturation, plasticity

A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate.

Lower levels of PHD2 protein influence tumor growth in mice

Tumors need a healthy supply of blood to grow and spread. Researchers at the Stanford University School of Medicine have identified a molecule that regulates blood vessel growth that is often found at less-than-normal levels in human tumors. Blocking the expression of the molecule, called PHD2, allows human cancer cells to grow more quickly when implanted into mice and increases the number of blood vessels feeding the tumor.

Old drug Auranofin may lead to new antibiotics

A mineral found at health food stores could be the key to developing a new line of antibiotics for bacteria that commonly cause diarrhea, tooth decay and, in some severe cases, death.
