Assessment of Histopathological Grade and Ki-67 Expression in Tobacco and Non-tobacco Habitual Buccal Mucosa Cancer.

Although there are various risk factors in the literature, the established primary risk factor for oral cancer is tobacco and betal-nut chewing habits. It is believed that pathogenesis of oral cancer depends on the aetiology. To assess the histopathological grade and Ki-67 expression in tobacco (smoking/smokeless) and non-tobacco (betal nut/pan masala) habitual buccal mucosa cancer.

Reversal of high fat diet-induced obesity through modulating lipid metabolic enzymes and inflammatory markers expressions in rats.

In this study, we evaluated the ameliorative potential of Cucurbita maxima seeds oil (CSO (100 mg/kg body weight)) supplementation to high fat diet (HFD)-induced obese rats for 30 days on the changes in body weight, markers of lipid metabolism such as LDL, HDL, triglycerides, total cholesterol, adiponectin, leptin, amylase, and lipase. We also investigated the effects of CSO on the changes of lipid metabolic enzymes such as fatty-acid synthase, acetyl CoA carboxylase, carnitine palmitoyl transferase-1, HMG CoA reductase, and inflammatory markers (TNF-α and IL-6). Administration of CSO revealed significant diminution in body weight gain, altered the activity, expressions of lipid marker enzymes and inflammatory markers.

The relationship between histological differentiation and disease recurrence of primary oral squamous cell carcinoma.

Background: Although advance techniques were available for diagnosis and prognosis of oral cancer, histopathology was used as major method in clinical routine. Of all oral subsites, buccal mucosa squamous cell carcinoma is aggressive in nature with poor survival. Therefore, the aim of the present study was to evaluate the relation of tumor histopathological grade with disease recurrence of buccal squamous cell mucosa carcinoma.

Anti obese potential of Cucurbita maxima seeds oil: effect on lipid profile and histoarchitecture in high fat diet induced obese rats.

In this study, we made an attempt to evaluate the potential of Cucurbita maxima seeds oil (CSO) against high-fat diet (HFD)-induced obesity in rats. We investigated the effect of CSO (100 mg/kg body weight) supplementation over 30 days on the changes of HFD-induced obese rats in body weight, biochemical parameters and lipid profile as well as investigated the effects of CSO on the histopathological changes. Oral administration with CSO revealed significant diminution in body weight gain, glucose and insulin levels, which altered the activity of lipid profile and restored the pathological alterations.

Obesity-alleviating potential of asiatic acid and its effects on ACC1, UCP2, and CPT1 mRNA expression in high fat diet-induced obese Sprague-Dawley rats.

The present study evaluated the effects of asiatic acid (AA), a pentacyclic triterpenoid from Centella asiatica on lipid metabolism parameters in a rat model of obesity induced using a high fat diet (HFD) for 42 days. AA (20 mg/kg body weight [BW]) was administered orally once daily for 42 days, and an orlistat-treated group of rats (10 mg/kg BW) was included for comparison. Changes in BW, blood glucose levels, insulin resistance and leptin, adiponectin, amylase, and lipase levels in the blood; lipid profiles of plasma; liver antioxidants levels; and acetyl CoA carboxylase(ACC), uncoupling protein-2 (UCP2), and carnitine palmitoyltransferase-1 (CPT1) mRNA expression were observed in the experimental rats.

Buccal Mucosa Carcinoma: A Comparative Relative Risk Analysis between Tobacco and Non Tobacco Users.

Introduction: In South India, buccal mucosa carcinoma is common cancer due to widespread use of tobacco in different form. Recently, areca nut (non tobacco) chewing habits have increased among young adults resulting in high morbidity and mortality. Thus, there is need to understand role of aetiology and risk of disease.

Reversal of endothelial dysfunction in aorta of streptozotocin-nicotinamide-induced type-2 diabetic rats by S-Allylcysteine.

Dietary measures and plant-based therapies as prescribed by native systems of medicine have gained attraction among diabetics with claims of efficacy. The present study investigated the effects of S-Allylcysteine (SAC) on body weight gain, glucose, insulin, insulin resistance, and nitric oxide synthase in plasma and argininosuccinate synthase (AS) and argininosuccinate lyase (ASL), lipid peroxides and antioxidant enzymes in aorta of control and streptozotocin-nicotinamide (STZ-NA)-induced diabetic rats. Changes in body weight, glucose, insulin, insulin resistance, and antioxidant profiles of aorta and mRNA expressions of nitric oxide synthase, AS, and ASL were observed in experimental rats.

Simultaneous Determination of Adenine and Guanine Using Cadmium Selenide Quantum Dots-Graphene Oxide Nanocomposite Modified Electrode.

A novel electrochemical sensor was fabricated by immobilizing Cadmium Selenide Quantum Dots (CdSe QDs)-Graphene Oxide (GO) nanocomposite on a paraffin wax impregnated graphite electrode (PIGE) and was used for the simultaneous determination of adenine and guanine. The CdSe QDs-GO nanocomposite was prepared by ultrasonication and was characterized with spectroscopic and microscopic techniques. The nanocomposite modified electrode was characterized by cyclic voltammetry (CV).
