Rats infected as newborns grew up vulnerable to memory problems during an immune challenge
Underscoring the value of good prenatal care, new research suggests that early infection may create a cognitive vulnerability that appears later during stress on the immune system. Researchers at the University of Colorado at Boulder have reported that rats who experienced a one-time infection as newborns didn't learn as well as adult rats who were not infected as pups, after their immunity was c...Low level of extinction during ice age linked to adaptability
A Johns Hopkins University graduate student may have figured out why rates of extinction were so low for many of the major groups of marine life during one of the greatest ice ages of them all, which occurred from about 330 million to 290 million years ago, late in the Paleozoic Era. The likely answer: because those aquatic life forms that did survive during this era were singularly equipp...Key mechanism in genetic inheritance during cell division identified
A key mechanism in the passing of genetic material from a parent cell to daughter cells appears to have been identified by a team of Berkeley researchers. Their study may explain how a complex of proteins, called kinetochores, can recognize and stay attached to microtubules, hollow fibers in the walls of biological cells that are responsible for the faithful segregation of chromosomes during cell...Too much water may be as dangerous as too little during long-distance athletic events
Drinking water during a long-distance race may do serious harm rather than keep you safe from injury if you're drinking too much, according to a cardiologist at UT Southwestern Medical Center. Runners or any long-distance athletes who drink too much water during a race could put themselves at jeopardy for developing hyponatremia, a condition marked by a loss in the body's sodium content th...Columbia study shows widely used artery clearing device does not help patients during heart attack
Interventional cardiologists from Columbia University Medical Center have shown that a commonly used procedure to remove fatty debris from blocked arteries during a heart attack does not improve patient outcomes. The procedure, called distal microcirculatory protection, is commonly and successfully used during angioplasty in vein grafts and stenting in carotid arteries. The study, publish...Addition of imidazole during binding improves purity of histidine-tagged proteins
GPC Biotech AG, Martinsried, Germany The purity of histidine-tagged proteins* purified by metal chelate affinity chromatography can often be improved by optimizing the imidazole concentration in the sample and binding buffer to achieve a balance between purity and yield of the protein of...Midwest biotech stocks drop like a rock during the third quarter
As he was born on Oct. 9, 1940, he would have been 65 years old if he was still alive. He was shot outside his apartment building on Dec. 8, 1980. He was 40 years old. The article gave a fascinating perspective on probably the most in...IMA wants members not to do sex determination tests during pregnancy
The Indian Medical Association has asked its members to refrain from conducting sex-determination tests and aiding female foeticide. No support would be extended to practitioners caught in the act, the IMA said on Sunday. "We as an organisation should warn our members against aiding in such heinous crimes", said Dr. Vinay Agarwal, joint secretary, IMA headquarters, New Delhi. He was spe...Heart Attacks during Menstruation!
Women with heart disease are more likely to have severe symptoms and possibly a heart attack at the beginning of their monthly menstrual cycle, according to new research from England. Angina is a heavy, squeezing chest pain which occurs when there is insufficient oxygen supply to the heart. It is more common in patients //with a history of heart disease. Researchers from the Cardiot...Cigerettes unsafe during pregnancy
One-third of SIDS deaths could be prevented if all pregnant women stopped smoking, say Australian researchers, arguing that healthcare providers need much more support and training in helping women quit.They found that smoking doubles the risk of having a low birth weight baby, a miscarriage or a pre-term birth, and triples the rate of SIDS - and if women are not able to give up entirely,...Strokes increased during squatting
Squatting may increase the risk of stroke, particularly if a person is defecating, researchers suggest.Doctors in Calcutta, India found a third of stroke deaths occurred while people were squatting.// Results presented to the World Congress of Neurology in London showed how doctors started investigating when they realised they were seeing more stroke patients in the morning than any other...
