Role of Oxidative Stress and the Protective Effect of Fermented Papaya Preparation in Sickle Cell Disease.

Fermented papaya preparation (FPP) is the source of antioxidants that may help in reducing the complications associated with oxidative stress and may improve the quality of life in sickle cell disease patients. In this study, we assessed the effect of FPP on sickled red blood cells (RBCs) using oxidative stress markers and observed that FPP has the potential to reduce the oxidative stress. Scanning electron microscopy (SEM) and eosin 5' malaemide (E5'M) dye test showed that FPP protects red cell morphology against the oxidative stress.

Role of MMP-2 and its inhibitor TIMP-2 as biomarkers for susceptibility to systemic lupus erythematosus.

To investigate the possible association between (-1575 G/A, -1306 C/T) and its inhibitor (-418 G/C) functional polymorphisms with development of severity in systemic lupus erythematosus (SLE) patients. 150 SLE patients and matched healthy controls were recruited. Polymorphisms were detected by PCR-RFLP and serum levels by ELISA.

A functional SNP MCP-1 (-2518A/G) predispose to renal disorder in Indian Systemic Lupus Erythematosus patients.

Systemic Lupus Erythematosus (SLE) is a clinically heterogeneous chronic, inflammatory autoimmune disorder that affects multiple organs where exact etiology of the disease is not yet clearly understood. Various evidences suggest that genetic polymorphisms in inflammatory mediators like cytokines and chemokines may influence development of the disease. Here, we investigated whether functional polymorphism at the Monocyte Chemoattractant Protein-1 (MCP-1) regulatory region associates with disease phenotype in Indian SLE patients.

Impact of TNF-α and LTα gene polymorphisms on genetic susceptibility in Indian SLE patients.

The promoter polymorphisms of tumour necrosis factor-α (TNF-α) and intronic Lymphotoxin-α (LTα) have been implicated as genetic risk factors for systemic lupus erythematosus (SLE) in various ethnic groups. The aim of this study was to investigate an impact of TNF-α (-308G/A; 238G/A) and LTα (+252A/G) gene polymorphisms in disease susceptibility among Indian 200 SLE patients along with 201 healthy controls. The gene polymorphisms were studied by using direct DNA sequencing and Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) methods.
