Healthcare access and a high quality of the provided services to healthcare users are fundamental human rights according to the Alma Ata Declaration of 1978. Although 45 years have passed since then, health inequalities still exist, not only among countries but also within populations of the same country. For example, several small Greek islands have only a small Primary Healthcare Center in order to provide healthcare services to the insular population.

In this study, we investigated the self-reported (questionnaire-based) prevalence of Obstructive Sleep Apnoea Syndrome (OSAS) and the prevalence of Chronic Obstructive Pulmonary Diseases (COPD) in the context of demographics and adherence to the Mediterranean diet in the general population of Alonissos, a non-profit line island in Greece (i.e., with scarce boat transportation to the mainland).

The pericardium is one of the serosal cavities of the mammals. It consists of two anatomical structures closely connected, an external sac of fibrous connective tissue, that is called fibrous pericardium and an internal that is called serous pericardium coating the internal surface of the fibrous pericardium (parietal layer) and the heart (visceral layer) forming the pericardial space. Between these two layers a small amount of fluid exists that is called pericardial fluid.

Background: Because clopidogrel is converted to its active metabolite by P450 isoenzymes, which are also involved in the metabolism of omeprazole, there is concern regarding whether the action of clopidogrel would be reduced in patients also taking omeprazole.

Objective: To evaluate the impact of omeprazole administration on the effectiveness of clopidogrel drug therapy during the first year following successful coronary stenting (CS).

Methods: A total of 588 consecutive patients who underwent successful CS for stable or unstable coronary artery disease were studied.

The permeability for small solutes and the ultrafiltration capacity of the peritoneum are essential for effective peritoneal dialysis (PD) treatment. Elucidation of the factors that regulate these two properties is therefore of great importance. Ouabain, a potent inhibitor of the Na+-K+ pump has been shown to reduce fluid absorption in animal models of PD.

The peritoneal mesothelium is one of the main barriers to ion transport in peritoneal dialysis. In a previous study, we showed the existence of a micro-opioid influence on the in vitro ionic permeability of serosal membranes (specifically, pleura and pericardium), which become less permeable to ionic currents after the action of morphine. In the present study, we used Ussing chamber experiments to investigate the effect of morphine on the transmesothelial electrical resistance (RTM) of isolated parietal sheep peritoneum.

This article reports on the development of a simple and cost-effective bioassay for the detection of biotin in urine and serum, based on the very selective binding of avidin and biotin. Avidin was allowed to react without isolating it from egg white. Egg white was treated with the dye HABA, which binds to avidin.

The effect of morphine (mu-opioid receptor agonist) on the transmesothelial resistance (R(TM)) of sheep's pleura and parietal pericardium was studied using the Ussing chamber technique. Basal transmesothelial resistance of parietal pleura was found to be 19.57+/-0.
