Lack of association between - 308 tumor necrosis factor polymorphism and susceptibility to cerebral malaria among Central Sudanese children

May 2010

  Up to 500 millions are affected by malaria parasite each year and only 1% of them develop severe clinical forms of the disease. No full satisfactory explanation for the fact that only small proportion of malaria infected individuals develops severe clinical phenotypes while others don’t. The aims of the present study is to assess the role of TNF-α - 308 G>A in predisposing to cerebral malaria...

Study of proteinase activity of Lactobacillus plantarum NCIM 2083

April 2009

Lactobacilli are important organisms used in several lactic acid fermentations. Lactobacilli cultured in milk perform activities like breaking down of lactose to simple sugars, proteolysis, lipolysis and lactic acid production. Lactobacillusdepends on proteolytic system for degradation of protein – casein in milk from which they get their complex nutrient requirements for growth. This complex proteolytic...
