Title: Studies on phthalate toxicity: A multigenerational assessment at ‘Neuroscience and Toxicology’ lab, Dept. of Zoology, Bangalore University, Bangalore.
- Guided Project
Title: Synergetic Effect of Radiation and Antioxidant on Silk performance of Silk worm, Bombyx mori
Bombyx mori, the most widely used species in silk farming. The usage of enriched mulberry diet with antioxidants and radiation exposure had a high potential to increase the synthesis of total proteins, glycogen and cholesterol in silk gland’s distinct regions namely anterior, middle and posterior as well as in hemolymph found highly beneficial to farmers and sericulture industry to enhance the silk production.

Title: Extracts from Natural Products for Drug Screens
Shellfish are contaminated with toxins by filter feeding on dinoflagellates species such as Dinophysis, epibenthic Prorocentrum species leading to diarrheic shellfish poisoning (DSP). Dinophysis and Prorocentrum species synthesizes okadaic acid, the lipophilic marine biotoxin which can cause diarrheic shellfish poisoning in humans due to ingestion of shellfish contaminated by toxic dinoflagellates. This toxin is released from the sulphated precursors by the action of esterases in the digestive tract of shellfish or by enzymes during the extraction of dinoflagellates in the laboratory. The extraction of active compounds such as okadaic acid from shellfish for drug screens found to be very crucial.

Title: Mutigenerational assessment of phthalate toxicity in albino rats
The environmental exposure to phthalate esters (plasticizers) has contributed a major threat to humankind. Di-n-butyl phthalate (DBP), one among the plasticisers administered to rats for three-generations during gestation and lactation are witnessed with cognitive impairments. The neurobehavioral deficit was evidenced with poor learning and memory in rats. Further, the impact of DBP exposure in rats was remarkable in altered histoarchitecture of discrete regions of brain as well revealed antagonistic effects of DBP on thyroid function through changes in neurotransmitter release and their signalling. This was speculated when rats in the developing stage exposed to DBP for three-generations had repercussions as poor neurobehavioral outcomes due to epigenetic mechanism. The extent of vulnerability was witnessed in this study was higher in F3 progeny than F1 and F2, a key indicator of cumulative and compounded effects. The demonstration of the teratogenic and neurotoxic potential of DBP in rats was also associated maternal toxicity and pup mortality.
