Salivary Oxidative Stress and Antioxidant Capacity in Smokeless Tobacco (Naswar) Users.

Background: Naswar, a smokeless tobacco product, commonly consumed in Pakistan, is associated with a 10-fold increase in the risk of oral cancer. However, little is known about Naswar's underlying toxicity mechanisms.

Objective: The current study aimed to investigate the effects of Naswar use on oral health and salivary parameters.

Isolation and characterization of indigenous bacterial assemblage for biodegradation of persistent herbicides in the soil.

Extensive pesticides (herbicides) use is negatively disturbing the environment and humans. Pesticide bioremediation with eco-friendly techniques bears prime importance. This study aimed to isolate and characterize three different herbicides (metribuzin, clodinafop- propargyl, MCPA (2-methyl, 4 chlorophenoxyacetic acids) and Bromoxynil) degrading bacterial strains from agricultural fields of Punjab University, Pakistan.
