diet and stomach cancer: a case-control study in south india.	a prospective case-control study was conducted in trivandrum, india, to evaluate the dietary risk factors for stomach cancer. one hundred and ninety-four patients with stomach cancer registered at the regional cancer centre (rcc), trivandrum, kerala, india, during the period 1988-1991 were considered as cases. a minimum of one control (n = 305), matched for age (+/- 5 years), sex, religion and residential area was selected from the visitors to rcc during the same period. interviews were carried ...	2000	10830575
rhodoplanes pokkaliisoli sp. nov., a phototrophic alphaproteobacterium isolated from a waterlogged brackish paddy soil.	a gram-negative, rod-shaped, purple non-sulfur bacterial strain, designated ja415t, was isolated from the mud of a pokkali rice field located on vypeen island, ernakulam, kerala, india. strain ja415t was motile by means of a single polar flagellum. photo- and chemo-organoheterotrophic growth was observed using organic compounds as carbon sources and electron donors. photo- and chemolithoautotrophic growth using thiosulfate as electron donor did not occur. fermentative growth could not be demonst ...	2009	19605702
physicochemical and genetic analysis of an endemic rice variety, njavara (oryza sativa l.), in comparison to two popular south indian cultivars, jyothi (ptb 39) and ir 64.	njavara is a medicinal rice strain, endemic to kerala, south india, bestowed with medicinal qualities. genetic variations and some of the physicochemical properties were studied using standard molecular protocols and compared with those of nonmedicinal rice varieties: jyothi and ir 64. njavara showed 11 unique positive and 36 unique negative markers to differentiate it from jyothi and ir 64. genetic similarity coefficient studies showed two well-defined clusters separating njavara from jyothi an ...	2009	19924858
