An ex vivo study of selenium, genistein on the morphological and nuclear changes in anticancer drug-induced apoptosis in human peripheral blood lymphocytes.

Behavioral difference of cancer cells and normal cells to anticancer drugs is diverse. Debilitating side effects observed with certain chemotherapeutic and prophylactic anticancer drugs have lead to identification of natural agents that may offer protective role against the damage induced in normal cells. The present study aimed to determine the protective role of the micronutrient mineral selenium (Se) and plant product genistein (Gn) in synergy and single, against the apoptosis induced in human peripheral blood lymphocytes by the cytotoxic agents cisplatin and mitomycin C.

Genetic admixture studies on four in situ evolved, two migrant and twenty-one ethnic populations of Tamil Nadu, south India.

We analysed the genetic structure of ≈ 1000 samples representing 27 ethnic groups settled in Tamil Nadu, south India, derived from two linguistic families (Dravidians and Indo-Europeans) representing four religious groups (Hinduism, Islam, Christianity and Jainism) using 11 mtDNA markers. Out of 27 ethnic groups, four are in situ populations (Anglo-Indian, Labbai Muslim, Nadar Christian and south Indian Jain) and two are migrants (Gypsy and north Indian Jain) from north India to Tamil Nadu, and 21 are native ethnic groups. Six of the markers we used were monomorphic (HaeIII663, HpaI3592, AluI5176, AluI7025, AluI13262, 9-bp deletion) and five markers were polymorphic (DdeI10394, AluI10397, HinfI12308, HincII13259 and HaeIII16517).
