Scientists Replicate Hepatitis C Virus in Laboratory

For the first time, scientists have replicated hepatitis C virus (HCV) in the laboratory. The ability to replicate HCV in cell culture will allow researchers to better study the life cycle and biology of this virus and to test potential antiviral compounds, which may lead to new therapies for the liver disease that results from infection with HCV. Scientists at the National Institute of Diabetes...

Novel Therapy Tested in Mice Could Chase Away Cat Allergies

A molecule designed to block cat allergies successfully prevented allergic reactions in laboratory mice, as well as in human cells in a test tube, University of California, Los Angeles (UCLA) researchers report in the April issue of Nature Medicine, available online now. In the future, the investigators say, these promising results could lead to a new therapy not only for human cat allergies, but...

New imaging method gives early indication if brain cancer therapy is effective, U-M study shows

A special type of MRI scan that measures the flow of water molecules through the brain can help doctors determine early in the course of brain cancer regimen if a patient's tumor will shrink, a new study shows. Researchers at the University of Michigan Comprehensive Cancer Center developed the assessment, which they call a functional diffusion map. They used a magnetic resonance imaging sc...

Elephants imitate sounds as a form of social communication

Elephants learn to imitate sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today's Nature, further supports the idea that vocal learning is important for maintaining individual social relationships among animals that separate and reunite over time, like dolphins and whales, some bi...

An entropy-based gene selection method for cancer classification using microarray data

Accurate diagnosis of cancer subtypes remains a challenging problem. Building classifiers based on gene expression data is a promising approach; yet the selection of non-redundant but relevant genes is difficult. The selected gene set should be small enough to allow diagnosis even in regular clinical laboratories and ideally identify genes involved in cancer-specific regulatory pathways. Here an...

Virus classification

can be classified in several ways, such as by their geometry, by whether they have envelopes, by the identity of the host organism they can infect, by mode of transmission, or by the type of disease they cause. The most useful classification is probably by the type of nucleic acid the virus contains and its mode of expression. Th...

Advances in Treatment of Cataracts

Cataracts occur when the eye's lens becomes cloudy and obstructs the passage of light to the retina. These obstructions can lead to vision loss. //Cataract is a major cause of blindness in India. Modern corrective surgery requires implantation of artificial lenses, however these implants often leave patients dependent on eyeglasses. But now, a recent study at Harvard Medical School has sh...

Kidney Stones - Interesting New Research implicates bacteria as its cause

In India Kidney Stones are not uncommon problem due to the hot and often humid weather. Most of these stones are made up of Calcium, Oxalate and phosphates. The cause of stone disease is debatable, however it is well known that drinking less water is a risk factor for stone disease. New research by the National Kidney foundation suggests that the culprit is a tiny bacteria called N...

What happens when Medications go wrong?

Or worse still if harmful drugs are tested on unwitting patients what happens? Who answers these questions? In a shocking revelation, a study in the U.S.A. has revealed that in many instances about a th...

Paracetamol May Cause Live Damage Warns Consumer Education and Research Centre

The Consumer Education and Research Centre (CERC) in Ahmedabad has alerted the Drug Control General of India against the excessive use of paracetamol. CERC says that the commonly use drug might cause potential liver damage and might lead on to liver failure. CERC Secretary Ashwini Kumar warns that consumers must be aware of the potential hazards of paracetamol more so because it is bein...

Cats to protect children from asthma

Scientists have found that children who kept cats as pets had developed a better immune system against asthma. This finding was originally thought to suppport the "hygiene"or "cleanliness" hypothesis. According to this, a lack of early exposure to bacteria or allergens keeps one branch of our immune system, mediated by "Th1" from developing properly. As a result, the immune syst...
