To Estimate the Prevalence of Obesity and High Blood Pressure among Undergraduate Students at a University Medical Institution in North India.

: Hypertension is a major public health issue in India. Early detection and management of high blood pressure (BP) is crucial, especially among young adults. This study aimed to estimate the prevalence of obesity and hypertension among undergraduate medical students.

Nickel-Catalyzed Tandem Cyclization of 1,6-Diynes with Indolines/Indoles through Dual C-H Bond Activation.

A nickel-catalyzed site-selective tandem cyclization of 1,6-diynes with substituted indolines or indoles through consecutive dual C-H bond activation is described. In the reaction, substituted fused indole and carbazole derivatives were observed in good to excellent yields, in which three consecutive C-C bonds formed in one pot. Later, in the presence of DDQ, the aromatization of the indoline derivative was converted to the indole derivative.

The Taq 1 polymorphism of Vitamin D receptor gene is associated with oral cancer and preoral cancer in North Indian population.

Background: Oral cancer is known as one of the most common cancers, with a poor prognosis, related to delayed clinical diagnosis, either due to the lack of particular biomarkers related to the disease or costly therapeutic alternatives.

Aims And Objectives: In this study association of single nucleotide polymorphism (Taq1, T>C) in Vitamin D receptor gene with oral cancer and pre oral cancer was studied.

Materials And Methods: Total 230 patients of precancerous oral lesions (Leukoplakia 70, Oral Sub mucous fibrosis 90, Lichen Planus 70), 72 oral cancer patients and 300 healthy control subjects were genotyped by PCR-RFLP methods.

XRCC3 and NBS1 gene polymorphisms modulate the risk of pre-oral cancer and oral cancer in the North Indian population.

Background: Oral cancer is alarming disease in the developing countries like India. DNA repair capacity may affect by genetic polymorphisms in DNA repair genes and thus may cause to cancer. XRCC3 involves in homologous recombination repair pathway and repair DNA damage and crosslinks while, NBS1 participate in repair of double strand DNA break and starts the cell-cycle checkpoint signaling.

Cobalt(III)-Catalyzed Regioselective [4 + 2]-Annulation of -Chlorobenzamides with Substituted Alkenes.

A Co(III)-catalyzed redox-neutral [4 + 2] annulation of -chlorobenzamides/acrylamides with substituted alkenes at ambient temperature is demonstrated. Using this protocol, pharmaceutically important 3,4-dihydroisoquinolinone derivatives were synthesized in good yields. Intriguingly, the synthetically useful functional group of allylic coupling partners such as sulfonyl, carbonate, acetate, phosphate, amide, nitrile, and silane were retained in the final cyclized product.

A Case Series on Neuropathogenic Nature of an Ancient Disease ----Tuberculosis.

Unlabelled: Tuberculosis is one of the oldest diseases known to affect humans and the top cause of infectious death worldwide caused by M. tuberculosis complex. Tuberculosis may be pulmonary, extra-pulmonary or both.

Cobalt(III)-Catalyzed Chemo- and Regioselective [4 + 2]-Annulation of Aromatic Sulfoxonium Ylides with 1,3-Diynes.

Air-stable, highly abundant, and cost-effective Co(III)-catalyzed redox-neutral [4 + 2]-annulation of aromatic sulfoxonium ylides with 1,3-diynes providing useful substituted 1-naphthol derivatives in a regioselective manner is described. Further, the prepared 1-naphthols having internal alkyne were converted into useful polycarbocyclic molecules and spiro-dienone derivatives in good-to-excellent yields. A possible reaction mechanism involving C-H activation as a key step was proposed and supported by deuterium labeling and kinetic isotope labeling studies.

Risk Modulation of Oral Pre Cancer and Cancer with Polymorphisms in XPD and XPG Genes in North Indian Population.

Background: Environmental carcinogens cause DNA damages which if not repaired properly, may increase the risk of cancer. The Xerodermapigmentosum group D (XPD) and group G (XPG) genes are essential genes for DNA repair and alteration in DNA repair causes cancer. The present study aimed to evaluate the relationship between XPD and XPG polymorphisms and risk of oral pre cancer and cancer.

Modulation of risk of squamous cell carcinoma head and neck in North Indian population with polymorphisms in xeroderma pigmentosum complementation Group C gene.

Background: Genetic variations in nucleotide excision repair genes can alter the risk of squamous cell carcinoma of head and neck (SCCHN).

A biphasic response of hepatobiliary cholesterol metabolism to dietary fat at the onset of obesity in the mouse.

Human obesity is associated with abnormal hepatic cholesterol homeostasis and resistance to leptin action. Because leptin administration to rodents promotes the biliary elimination of plasma cholesterol, this study was designed to elucidate a pathophysiological role for leptin during the development of obesity. We fed mice diets containing high or low saturated fat contents.

Impaired response of biliary lipid secretion to a lithogenic diet in phosphatidylcholine transfer protein-deficient mice.

Phosphatidylcholine transfer protein (PC-TP) is a cytosolic lipid transfer protein that is highly expressed in liver and catalyzes intermembrane transfer of phosphatidylcholines in vitro. To explore a role for PC-TP in the hepatocellular trafficking of biliary phosphatidylcholines, we characterized biliary lipid secretion using Pctp(-/-) and wild-type littermate control mice with C57BL/6J and FVB/NJ genetic backgrounds, which express PC-TP at relatively high and low levels in liver, respectively. Eight-week-old male Pctp(-/-) and wild-type mice were fed a chow diet or a lithogenic diet, which served to upregulate biliary lipid secretion.
