background: oral squamous cell carcinoma (oscc) is one of the most common malignant tumors. its incidence is rated as one among the highest in the world and the use of tobacco in various forms is increasingly associated with the cause of oscc. in oral cancer the study of tumor markers have been limited and several tumor makers with clinical promise needs further evaluation. methods: present stu...

dialysis-related amyloidosis (dra) is characterized by accumulation of amyloid β2-microglobulin (β2m) in the interstitial matrix. matrix substances such as heparin have reportedly been strongly implicated in the pathogenesis of dialysis-related amyloidosis. in clinical setting of hemodialysis, two types of heparin, i.e., high and low molecular heparin (h.m.h. and l.m.h.) have been routinely use...

Allogeneic mesenchymal stem cells (MSCs) are a promising cell source for treating musculoskeletal injuries in horses. Effective and safe allogeneic therapy may be hindered, however, by recipient immune recognition and rejection of major histocompatibility complex (MHC)-mismatched MSCs. Development of strategies to prevent immune rejection of MHC-mismatched MSCs in vivo is necessary to enhance c...

Growth differentiation factor 11 (GDF-11) has been implicated in reverse effects of ageing on the central nervous system of humans. β2-microglobulin (β2-MG) has been reported to negatively regulate cognition. However, there is a lot of controversy about the role of GDF-11 and β2-MG in ageing and cognitive regulation. To examine the involvement of GDF-11 and β2-MG in the ageing process and cogni...

OBJECTIVE Beta-2-glycoprotein I (β2 GPI) constitutes the major autoantigen in the antiphospholipid syndrome (APS), a common acquired cause of arterial and venous thrombosis. We recently described the novel observation that β2 GPI may exist in healthy individuals in a free thiol (biochemically reduced) form. The present study was undertaken to quantify the levels of total, reduced, and posttrans...

The effect of β2-adrenergic receptor (AR) overexpression on interleukin (IL)-10 content secreted by cardiomyocytes of heart failure (HF) rats was investigated. A rat model of chronic HF was established by partially banding abdominal aorta and the cardiomyocytes were isolated with collagenase II. The cardiomyocytes were then transfected with adenovirus type 5-ADRβ2-enhanced green fluorescent pro...

The body is under constant attack from pathogens trying to slip by our immune defence. If the barrier is breached, invading pathogens enter the tissues and cause inflammation. During this process neutrophils, constituting the first line of defence, leave the bloodstream and seek out and kill the invading pathogens. The mechanisms leading to activation of receptors on neutrophils must be closely...

The stability constants of complexes formed by Thallium (I) with Serine and Leucine have been investigated in aqueous medium, the complex with metal Serine as 1:1, 1:2 and complexes of the Tl(I) with Leucine as 1:1, 1:2 have been reported. The values of formation constant of Serine are log β1 = 2.1760, log β2 = 3.85325 at 308K and log β1 = 1.9030, log β2 = 3.6739 at 318K and complexes of Tl(I) ...

The primary molecular target for clinically used opioids is the μ-opioid receptor (MOR). Besides the major seven-transmembrane (7TM) receptors, the MOR gene codes for alternatively spliced six-transmembrane (6TM) isoforms, the biological and clinical significance of which remains unclear. Here, we show that the otherwise exclusively intracellular localized 6TM-MOR translocates to the plasma mem...

Leukocyte integrins of the β2 family are essential for immune cell-cell adhesion. In activated cells, β2 integrins are phosphorylated on the cytoplasmic Thr758, leading to 14-3-3 protein recruitment to the β2 integrin. The mutation of this phosphorylation site impairs cell adhesion, actin reorganization and cell spreading. Thr758 is contained in a Thr-triplet of β2 that also mediates binding to...
