Alteration in serum miR126 expression in healthy adults observing Navratri fast.

Background: Fasting is practiced by various religions in the world. The previous studies show the effect of fasting on biochemical markers in healthy subjects; however, no study is available on its effect on gene expression or epigenetic markers. In the present study, miR126, a microRNA, was measured in serum samples of healthy adult subjects, and their correlation with biochemical profile was carried out during the short-term fasting of the Navratri festival.

Association of promoter methylation status of NRF2 and PNPLA3 genes in alcoholic liver disease.

Background: Alcoholic liver disease (ALD) is the leading cause of chronic liver disease. In the liver, metabolism of alcohol occurs through multiple mechanisms and it results in the generation of various toxic products. Multiple genetic causes have been identified that are associated with the development and progression of ALD.

A pilot study on DNA hypermethylation status in promoter region of P16 gene in patients with sporadic breast cancer.

Background: Epigenetic modification of cancer-related genes plays a role over and above their genetic alterations and contributes to the tumor initiation and progression of breast cancer. Promoter methylation of tumor suppressor genes is one such epigenetic modification, which can be potential biomarker. In this study, promoter methylation status of p16 gene was studied in blood samples of patients with breast carcinoma.

Immunohistochemical analysis and correlation of cyclooxygenase-2 expression status with clinicopathological parameters in head and neck squamous cell carcinomas: An Indian perspective.

Context: Head and neck squamous cell carcinoma (HNSCC) poses a major health problem and despite the advancements in its diagnosis and management the overall survival has not improved significantly. A search for newer diagnostic and prognostic markers along with fresh molecular targets is required for its prevention and cure.

Aims: The study aims to study the expression of cyclooxygenase-2 (COX-2) in HNSCCs and investigate its correlation with the clinicopathological profile of these cases.

Prevalence of unsuspected glucose intolerance in coronary artery disease (CAD) patients: Importance of HbA1c.

Background: The mortality and morbidity rates are two to fourfold higher among Coronary Artery Disease (CAD) patients with type 2 diabetes mellitus (DM). American Diabetes Association (ADA) and World Health Organization (WHO) define different criteria for the diagnosis of glucose intolerance. This study compares the available diagnostic criteria for DM in Indian men and their importance in CAD patients.

Visceral leishmaniasis mimicking as second line anti retroviral therapy failure.

Visceral leishmaniasis (VL) has increased as a complicating infection in subjects with human immunodeficiency virus (HIV) in developing countries. Both infections tend to lower the cell-mediated immunity resulting in poor drug response. In HIV-positive subjects the clinical course as well as organ involvement of VL simulates tuberculosis, another very common tropical infection.
