Learning How SARS Spikes Its Quarry
Researchers have determined the first detailed molecular images of a piece of the spike-shaped protein that the SARS virus uses to grab host cells and initiate the first stages of infection.   view more (2005-09-16)

Linking 2 molecular pieces of the Alzheimer's puzzle
Researchers have uncovered a biological link between the protein whose mutation causes early-onset Alzheimer's disease (AD) and a gene variant linked to late-onset AD. The researchers said their finding could lead to new approaches to treating AD.   view more (2007-10-04)

'VALUE' study results: more evidence that angiotensin-receptor blockers can reduce blood pressure among patients at high cardiovascular risk (pp 2010, 2022, 2049)
Results of a study in this week's issue of THE LANCET provide further evidence that a class of drugs that lower blood pressure are a treatment option for older people at high cardiovascular risk. The study also emphasises the importance of early blood-pressure lowering after the start of treatment... view more (2004-06-16)

Unique vascular dysfunction in women's heart disease described in major journal supplement
Although ischemic heart disease - the reduction of blood flow that can lead to heart attacks - is often considered a "man's disease," it takes the lives of more women than men each year. In fact, in 2000, about 60,000 more women than men died from cardiovascular disease.   view more (2006-02-06)

Cancerous vs. healthy cells: Researchers identify the road to success
Conventional cancer treatments are generally effective in wiping out tumor cells, but in the process they also may kill healthy cells.   view more (2006-04-10)

New molecular regulators of hyperthyroidism and goiter
The thyroid gland has an important role in determining how much energy the body burns. Thyroid gland functions are regulated by a hormone known as thyroid-stimulating hormone (TSH).   view more (2007-08-10)

Researchers Reveal Possibility of Separating Anticancer Properties of Vitamin D
At the right dose, vitamin D is important for bone development and may help protect against the development of several cancers, particularly colorectal cancer.   view more (2006-03-20)

Biomarkers of response to VEGF pathway-targeted therapy discovered for renal cell carcinoma
Angiogenesis inhibitors can be far more effective in treating metastatic clear cell renal cell cancer (RCC)-an aggressive form of the most common kind of kidney cancer that is also rich in blood supply-than traditional treatments, according to accumulating evidence.   view more (2006-09-14)

Children's Hospital researchers identify molecular 'switch' that could save very young lives
A team of researchers at Children's Hospital of Pittsburgh of UPMC have identified a molecular "switch" that, when blocked, may help reverse necrotizing enterocolitis (NEC), a leading cause of death in premature infants.   view more (2007-12-05)

UCSD researchers identify critical receptor in liver regeneration
In studies in mouse models, researchers at the University of California, San Diego (UCSD) School of Medicine have found that a cellular receptor involved in triggering cell death is also a necessary component of tissue repair and regeneration immediately following liver injury.   view more (2007-03-30)

Hormone drug type makes survival difference in advanced breast cancer
Aromatase inhibitors, a type of hormone therapy used to treat advanced breast cancer in postmenopausal women, result in a small but significant increase in overall survival when compared to other hormone treatments, according to a new systematic review of studies.   view more (2007-01-31)

Studies suggest new brain protein may help in treating schizophrenia, insomnia and anxiety
A small protein in the brain that has only recently been discovered and, paradoxically, induces both profound wakefulness and a less anxious state, may represent a novel target for the treatment of psychotic behavior and schizophrenia.   view more (2006-06-23)

Western diet linked to increased risk of breast cancer in postmenopausal Asian women
Postmenopausal Asian women who eat a "meat-sweet" or Western diet are at greater risk of developing breast cancer than those who eat a "vegetable-soy" diet, according to a new study.   view more (2007-07-10)

Living taste cells produced outside the body
Researchers from the Monell Chemical Senses Center have succeeded in growing mature taste receptor cells outside the body and for the first time have been able to successfully keep the cells alive for a prolonged period of time.   view more (2006-02-27)

Scientists uncover the potential to control adult stem cells
Research being presented today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh represents a step towards the use of Adult Stem Cells (ASCs) to repair damaged tissue.   view more (2008-04-10)

UCLA scientists reveal how Nipah virus infects cells
UCLA scientists have discovered how the deadly Nipah virus infiltrates human cells to cause encephalitis. Designated as a potential bioterrorism agent by the National Biodefense Research Agenda, the virus exploits a protein essential to embryonic development to enter cells and launch its attack.   view more (2005-07-07)

The G allele of the mu-opioid receptor gene is linked to craving for alcohol
The study of genes and their influence on alcohol consumption can operate on many different levels. Some studies examine how genes may interact with the environment, some look specifically at family history of alcohol dependence, and some zero in on "pieces" of genes and their influence... view more (2007-01-04)

Benefit of cancer prevention surgery differs between women with BRCA1 and BRCA2 mutations
The surgical removal of the ovaries has been widely adopted as a cancer-risk-reducing strategy for women with either BRCA1 or BRCA2 mutations.   view more (2008-02-12)

Papers recently published online by Nature and the Nature Research Journals
NATURE MEDICINE(http://www.nature.com/naturemedicine) [1] Cadmium's disguise does damage to estrogen-sensitive tissues DOI: 10.1038/nm902 (http://dx.doi.org/10.1038/nm902) With 15,000 tons produced each year for batteries, alloys, and pigments, the heavy metal cadmium is one of the most serious... view more (2003-07-15)

A new idea for how anti-aging products delay ripening of fruit and wilting of flowers
When plants encounter ethylene, a gas they also produce naturally as a hormone, the result is softening and ripening in the case of fruit, and wilting and fading in the case of flowers - all of which ethylene promotes.   view more (2008-05-05)

Mayo Clinic researchers challenge sepsis theory
A Mayo Clinic research team has challenged the accepted theory on the cause of sepsis - a condition in which the body's cells generate fever, shock and often death.   view more (2006-02-08)

A scientific breakthrough on the control of the bad cholesterol
A study performed by the team of Dr. Nabil G. Seidah, Director of the Biochemical Neuroendocrinology Research Unit at the IRCM, shows for the very first time that the degradation by PCSK9 of the LDLR receptor   view more (2008-11-25)

UCLA study uncovers clues for why Graves' disease attacks the eyes
UCLA researchers have uncovered new clues that may explain why Graves' disease (GD) attacks the muscle tissue behind the eyes, often causing them to bulge painfully from their sockets, as in the late actor Marty Feldman.   view more (2007-03-01)

1 missing gene leads to fruitless mating rituals
