Surgical Site Infections in Gastrointestinal Surgeries: Estimation of Prevalence, Risk Factors and Bacteriological Profile.

Introduction: Surgical site infections (SSIs) are one of the leading causes of operation-related adverse effects. To create an effective hospital infection program, information about a local pattern is essential. The ever-changing pattern of infections and inappropriate use of antibiotics has predisposed to the development of drug-resistant strains and has made the management of SSIs arduous.

Functional variations between Mesenchymal Stem Cells of different tissue origins: A comparative gene expression profiling.

Background: Mesenchymal Stem Cells (MSCs), regardless of the tissue sources, are considered as excellent candidates for cellular therapy as they are immune-privileged cells containing a multitude of therapeutic functions that aid in tissue regeneration and repair. For the effective application of these cells in cell therapy, it is important to understand and characterize their biological functions.

Objectives: The present study attempts to characterize the variations in multipotent function such as cell surface antigen levels, proliferation, differentiation and stemness (pluripotency) potential of MSCs isolated from foetal [wharton's jelly (WJ), foetal and maternal side of placenta (PF and PM)] and adult tissue sources [bone marrow (BM) and adipose tissue (AT)] using gene expression by real time PCR (qRT-PCR).

Isolation, expansion and characterisation of mesenchymal stem cells from human bone marrow, adipose tissue, umbilical cord blood and matrix: a comparative study.

The multipotent and immunosuppressive capacities of mesenchymal stem cells (MSCs) attract several scientists worldwide towards translational research focusing on treatment of diseases including liver failure. Though MSC's have been isolated from different sources, researchers do not concur on the best source for expansion and clinical translation. In this study, we have compared the isolation, proliferation and expansion of MSCs from umbilical cord blood (UCB), Wharton's Jelly (WJ), bone marrow (BM) and adipose tissue (AT).
