The main objective of the present work was to study modifications in RBC aggregate morphology by analyzing digitized microscopic images and compare them between healthy subjects and patients suffering from essential hypertension. Blood samples were obtained from normal subjects (n=30) and patients suffering from essential hypertension (n=20). RBC aggregate morphology was quantified using direct microscopic observation and numerical analysis of images. ASP (Aggregation Shape Parameter) defined as the ratio of the area of the projected image to its square perimeter was calculated. Other rheological parameters have been determined in order to establish the hemorheological profile of the studied hypertension states. ASP appears significantly higher (p<0.001) in patients suffering essential hypertension (0.69+/-0.11) than in normal control subjects (0.25+/-0.12). RBC aggregation is known to be responsible for the high increase in apparent blood viscosity at low shear rates. By compare ASP values with whole blood viscosity at low rate (2.30 s(-1)) a high correlation was formed between both parameters (Spearman coefficient was 0.8835 and p<0.001). The applied method is simple, direct and quantitative and provides a useful tool for measuring deviations of RBC aggregate morphology. 相似文献

Background
Health-related quality of life (HRQL) in persons with multiple sclerosis (MS) who reside within the community relative to the general population is largely unknown. Data from the Canadian Community Health Survey Cycle 1.1 (CCHS 1.1) were used to compare HRQL of persons with MS and the general population. 相似文献67.

Type 2 diabetes mellitus (NIDDM) is a complex metabolic disease that occurs when insulin secretion can no longer compensate insulin resistance in peripheral tissues. At the molecular level, insulin resistance correlates with impaired insulin signaling. This review provides new insights into the molecular mechanisms of insulin action and resistance in brown adipose tissue (BAT) and pinpoints the role of BAT in the control of glucose homeostasis. 相似文献

OBJECTIVE: To assess public services attending female victims of sexual violence in the city of Sao Paulo. METHODS: This is a qualitative study conducted in two public services attending female victims of sexual violence. Interviews with 42 women were conducted, 13 of whom had sought these services for assistance and 29 were professionals working in these services. Evaluation of the services was based on the categories: reception, access, resolvability and sanitary responsibility. RESULTS: The analysis of the interviews per category has shown that there was reception in both services, problems with respect to access due to the lack of information concerning these services, and quality resolvability with a multi-professional team. As to the sanitary responsibility, it is present in these specialized services but is deficient in the emergency services and basic health care units. Many women are unaware of the rights they are entitled to with respect to specialized services. Frequently their late arrival compromises the efficacy of care. There are deficiencies both in terms of reference and counter reference. CONCLUSIONS: The results ratify the importance of these services and the need for their decentralized expansion. Health courses should introduce the theme of sexual violence at the undergraduate level. 相似文献
