Beijing  - China's nominal parliament on Saturday approved a new food safety law designed to stem a recent tide of scandals over tainted food products.

The Standing Committee of the annual National People's Congress, which approves policies and laws proposed by the ruling Communist Party, said the new law would help ensure food safety "from the production line to dining table."

London, February 28 : An international group of American and British scientists have found that the human immunodeficiency virus (HIV) has the ability to adapt to the body''s defence system, which suggests that any successful AIDS vaccine must keep pace with the ever-changing immunological profile of the virus.

Researchers at the University of Alabama at Birmingham (UAB) and the University of Oxford in England conducted a study that showed HIV adapts by spelling out at least
14 different "escape mutations" that help keep it alive after it interacts genetically with immunity molecules that normally attack the virus.

The researchers revealed that they analysed genetic data from more than 2,800 HIV-infected patients on five continents.

Recent study showed that fampridine, developed by Acorda Therapeutics Inc (ACOR. O) can help people with multiple sclerosis by improving their walk.

Recent study revealed that combination of two drugs can help in fighting extensively drug-resistant tuberculosis (XDR-TB).

Researchers said that AstraZeneca's (AZN. L) MERREM I. V., also called meropenem, used together with clavulanate, sold by GlaxoSmithKline (GSK. L) in combination with amoxicillin as the drug Augmentin, killed laboratory-grown strains of TB.

Recent study revealed that person sitting on the window seat faces double risk of developing a deep vein thrombosis (DVT) as compared to those sitting on the aisle or in a middle seat. A DVT clot can cause death if it passes through a passenger's bloodstream to the lungs, causing pulmonary embolism.

Research team from Leiden University Medical Centre found that obese people have six times higher risk of developing a blood clot when seated by the window. Hence obese passengers should prefer to sit either in the middle or aisle seats.

Recent research revealed that genetic variations affect the response of patient to treatment for lymphoblastic leukemia. Researchers believe that these genetic variations explain why some children do not respond to the treatment of this type of blood and bone marrow cancer although about 80 percent of children are cured.
