Gastric cancer is one of the common cancers seen in south India. Unfortunately more than 90% are advanced by the time they report to a tertiary centre in the country. There is an urgent need to characterize these cancers and try to identify potential biomarkers and novel therapeutic targets. We used 24 gastric cancers, 20 Paired normal (PN) and 5 apparently(More)
Cervical cancer is the most common cancer among Indian women. This cancer has well defined pre-cancerous stages and evolves over 10-15 years or more. This study was undertaken to identify differentially expressed genes between normal, dysplastic and invasive cervical cancer. A total of 28 invasive cervical cancers, 4 CIN3/CIS, 4 CIN1/CIN2 and 5 Normal(More)
The hypoglycaemic effect of orally administered extracts of leaves and roots of Coccinia indica has been reported earlier. The oral administration of the pectin isolated from the fruit of the above plant at a dose of 200 mg/100 g BW/day showed a significant hypoglycaemic action in normal rats. Pectins isolated from many other plants have also been reported(More)
OBJECTIVE Evaluation of the prognostic significance of c-Myc expression in carcinoma of the cervix. MATERIALS AND METHODS 132 patients with carcinoma of the cervix presenting at the Cancer Institute in Chennai from 1996-1999 were included in the study. All the cases were treated with a radical course of radiotherapy and had a median follow-up of 36(More)
BACKGROUND & OBJECTIVE A group of villages in Kollam district of Kerala, southern part of India are exposed to a higher dose of natural radiation than global average. Yet no adverse health effects have been found in humans, animals and plants in these areas. The present study was carried out to understand whether radiation affects the quantity and quality(More)
Oral administration of flavonoids extracted from unripe fruits of Musa paradisiaca showed significant hypolipidemic activities in male rats (Sprague Dawley strain) at a dose of 1 mg/100 g body weight (BW)/day. Concentrations of cholesterol, phospholipids, free fatty acids, and triglycerides showed significant decrease in the serum, liver, kidney, and brain(More)
Fractions rich in flavonoids obtained from the fruits of Punica granatum extract, orally administered to rats at dose of 10 mg kg(-1) day(-1), showed potential antiperoxidative effect. Concentrations of malondialdehyde, hydroperoxides and conjugated dienes were significantly decreased in liver while the activities of the enzymes catalase, superoxide(More)
Apoptosis maintains tissue homeostasis through its ability to control cell population and has been extensively studied in human cancers. Relation of apoptosis to prognosis is still controversial. In this study, we analyzed the prognostic significance of apoptotic and mitotic indices (AI & MI) using hematoxylin and eosin stained slides by light microscopy in(More)
Flavonoids from Emblica officinalis and Mangifera indica effectively reduce lipid levels in serum and tissues of rats induced hyperlipidemia. Hepatic HMG CoA reductase activity was significantly inhibited in rats fed E. officinalis flavonoids. But increase of this enzyme was observed in rats administered M. indica flavonoids. LCAT showed elevated levels in(More)
Flavonoids extracted from the fruits of Solanum melongena (Brinjal) orally administered at a dose of 1 mg/100 g BW/day showed significant hypolipidemic action in normal and cholesterol fed rats. HMG CoA reductase activity was found to be enhanced, while activities of glucose-6-phosphate dehydrogenase and malate dehydrogenase were significantly reduced.(More)
