INTRODUCTION The use of PRP has been studied for different fields, with promising results in regenerative medicine. Until now, there is no study in the literature evaluating thrombin levels in serum, used as autologous thrombin preparation. Therefore, in the present study we evaluated the role played by different thrombin concentrations in PRP and the impact in the release of growth factors. Al...

BACKGROUND The interaction of circulating microparticles (MPs) with immune cells in systemic lupus erythematosus (SLE) is sparsely investigated. We examined the ability of MPs from SLE patients to induce production of reactive oxygen species (ROS) and degranulation of polymorphonuclear leukocytes (PMNs). METHODS Plasma MPs, leukocytes and sera isolated from 20 SLE patients and 10 healthy cont...

The Triangular Fibrocartilage Complex (TFCC) Is A Well Defined Structure Located on Ulnar Aspect Of Wrist Functioning Primarily To Stabilize Distal Radio –Ulnar Joint (DRUJ) And Also Act As Shock Absorber Across Ulno-Carpal Joint.

Tears have antimicrobial, nourishing, mechanical, and optical properties. They contain components such as growth factors, fibronectin, and vitamins to support proliferation, migration, and differentiation of the corneal and conjunctival epithelium. A lack of these epitheliotrophic factors—for example, in dry eye, can result in severe ocular surface disorders such as persistent epithelial defect...

We studied the mechanisms underlying the natural tolerance of thymus-derived (T) lymphocytes for self-antigens. Lymphocytes from the thymus or lymph nodes of inbred rats were autosensitized in vitro against monolayers of autochthonous thymus reticulum cells or syngeneic fibroblasts. Receptors for self-antigens were detected by the specific adherence of normal lymphocytes to syngeneic cells. The...

BACKGROUND & OBJECTIVE Mannose binding lectin (MBL), a C-type or Ca(2+) dependent lectin, plays a major role in lectin pathway of complement activation. MBL deficiency/insufficiency is associated with susceptibility to many infections. It is important to know the association of functional lectin levels with disease condition. Therefore, we carried out this study to develop a simple assay to est...

BACKGROUND The clinical results of in vitro fertilization of slowly frozen-thawed oocytes are known to be significantly worse than those obtained by fresh oocytes. Little is known about the factors affecting the clinical outcome of frozen-thawed oocytes. The aim of this retrospective study was to explore the role of oocyte cryopreservation in the group of patients with no available sperm on the...
