Maintenance of appropriate cell adhesion is crucial for normal cellular and organismal homeostasis. Certain microRNAs have recently been found capable of regulating molecules that oversee the fundamental cell biological events that drive cellular adhesion. It is now apparent that microRNAs play crucial roles in the great majority of biochemical pathways that contribute to normal cell adhesion. ...

Sleep is hypothesized to have a role in the regulation of the immune system. This study evaluated the nocturnal expression of cellular adhesion molecules, Mac-1 and L-selectin on monocytes and lymphocytes during a full nights sleep and following a partial night of sleep deprivation (PSD). Healthy male subjects (n=16) had an increase in the percentage of Mac-1 positive lymphocytes across the bas...

Traditional medicine (a term used here to denote the indigenous health traditions of the world) and complementary and alternative medicine (T/CAM) have, in the past 10 years, claimed an increasing share of the public's awareness and the agenda of medical researchers. Studies have documented that about half the population of many industrialized countries now use T/CAM, and the proportion is as h...

Most patients (about 85%) seen in the ED to rule out an acute coronary event do not have acute coronary disease. In addition, the presenting ECG findings have been nondiagnostic in 50% of patients with acute MI. Our current knowledge of atherosclerosis as being a chronic low-grade inflammatory process triggered the search for reliable serum markers that have improved the diagnostic accuracy man...

Adhesion molecules mediate cell-cell and cell-matrix interactions and are essential for numerous physiological and pathological processes. Recent evidence from many laboratories suggests that adhesion molecules play an important role in tumor progression and may promote tumor growth and organ-specific metastasis. Certain adhesion molecules may also function as tumor suppressors. In this review,...

Endothelial cell activation and the cell surface expression of adhesion molecules are considered to be crucial steps in the systemic inflammatory response to cardiopulmonary bypass. Endothelial cell adhesion molecules mediate the process of leukocyte adhesion to the endothelium and their subsequent transmigration and degranulation in the subendothelial tissues. The levels of soluble endothelial...

Although many researchers agree that applying conventional drug-trial quality criteria to CAM studies lacks plausibility, few take on the burden of devising alternative criteria in a specific area of CAM. This commentary points out strengths and weaknesses in the approach taken in the work of Mathie and colleagues to do this for homeopathy.

Azaspiracids cause severe damages in the epithelium of several organs. In this study we have investigated the effects of azaspiracid-1 (AZA-1) on two epithelial cell lines. Nanomolar concentrations of AZA-1 reduced MCF-7 cell proliferation and impaired cell-cell adhesion. AZA-1 altered the cellular pool of the adhesion molecule E-cadherin by inducing a dose- and time-dependent accumulation of a...
