BRCA1 causes ovarian cancer through indirect, biochemical route

Mutated BRCA1 genes cause ovarian cancer indirectly, by interfering with the biochemical signals one ovarian cell sends to another, according to a team of researchers led by scientists at the USC/Norris Comprehensive Cancer Center and the Keck School of Medicine of the University of Southern California. Their work is being published in the March 29 issue of the journal Current Biology.</p...

Researchers discover molecule that causes secondary stroke

Scientists at the University of Cincinnati (UC) College of Medicine have discovered the cause of a deadly type of secondary stroke known as cerebral vasospasm. A constriction of the blood vessels in the brain, cerebral vasospasm usually occurs three to 10 days following a massive brain bleed known as hemorrhagic stroke. Sixty percent of patients who survive the initial stroke develop vasos...

NASA study finds snow melt causes large ocean plant blooms

A NASA funded study has found a decline in winter and spring snow cover over Southwest Asia and the Himalayan mountain range is creating conditions for more widespread blooms of ocean plants in the Arabian Sea. The decrease in snow cover has led to greater differences in both temperature and pressure systems between the Indian subcontinent and the Arabian Sea. The pressure differences gene...

New Estimates For The Causes Of Child Deaths Worldwide

The most accurate estimates of the causes of child deaths to date, published in the March 26, 2005 of THE LANCET, reveal that worldwide more than 70% of the 10.6 million child deaths that occur annually are attributable to six causes: pneumonia (19%), diarrhoea (18%), malaria (8%), neonatal sepsis or pneumonia (10%), preterm delivery (10%), and asphyxia at birth (8%). Robert Black (Johns H...

Alarm pheromone causes aphids to sprout wings

Chemical communication within insect species is often much more sophisticated than expected. When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-â-farnesene, that has long been known to cause other aphids to walk around or drop from the plant. In a paper soon to appear in Ecology Letters, researchers at the University and Max-Planck-Institut...

Breast Cancer Surgery Causes Psychological problems

About one third of women who undergo surgery for breast cancer will experience psychological problems, including obsessive-compulsive thoughts and anxiety following surgery, according to new research. Dr. Erica S. Breslau of Johns Hopkins University, Baltimore, Maryland, and colleagues reported the findings at the American Public Health Association's annual meeting. // The researchers...

Lack of solar radiation causes cancer

Exposure to UV-B radiation may cause skin cancer, but it also prevents many other cancers through activating vitamin D. According to many, UV-B - the solar radiation that causes sunburn// - as a risk factor for melanoma, and other skin cancers. That is generally true, but what is not generally realised is that the reverse may also be the case - that UV-B prevents cancer. Dr.William Gr...

Defective heart valve causes problems

According to researchers, a recent study shows that a leaky heart valve raises the risk of abnormal heart rhythms. In atrial fibrillation (AF) the upper chambers of the heart beat randomly and unsuccessfully. The condition is linked to heart attack and stroke.// Researchers at the University of Texas, have now shown that having a leaky heart valve - separating the upper and lower heart chambers...

Occupational Exposure To Radiation Causes Chromosome Aberrations

Professor Manoor Prakash Hande and his colleagues from National University of Singapore studied the effect of plutonium exposure and risk of developing Chromosomal aberrations leading to cancer// in Plutonium plant workers. The study is mainly aimed at identifying biomarkers for easy detection and identification of chromosome aberrations. The study is also aimed at finding a link between...

Abortion made easy pill causes alarm in state

Mifipriston, the new high-tech abortion drug being freely sold over the counter in the state, may usher in an era of do-it-yourself-abortions,// experts fear. Already, the sale is brisk as the tablets sell like laxatives, they claim, and even as the pharmaceutical concerns treat the city gynaecologists to five-star meals ostensibly to introduce them to “the revolutionary approach to medical abort...
