[Chronic metabolic syndrome: a predictive model of risk of macrovascular events?].

Objectives: To establish a predictive model of the risk of macrovascular complications in patients with Chronic Metabolic Syndrome by means of multiple logistic regression analysis. To identify Chronic Metabolic Syndrome as an independent health problem, given its frequency and importance in the genesis of macrovascular complications.

Design: A descriptive observational study.

Angiotensin I-converting enzyme genotypes and angiotensin II receptors. Response to therapy.

In the present study, we studied angiotensin II type 1 (AT1) and type 2 (AT2) receptor messengers by quantitative reverse transcriptase-polymerase chain reaction. We examined peripheral blood mononuclear cells from 30 healthy subjects and 50 subjects with primary hypertension, in whom angiotensin I-converting enzyme genotype was determined, before and after 15 days of treatment with different antihypertensive drugs. The medication included a calcium channel antagonist, an angiotensin I-converting enzyme inhibitor, and a beta 1-blocker.

Direct quantification of HIV-1 RNA in human plasma by free solution capillary electrophoresis (FSCE).

The levels of human immunodeficiency virus type 1 (HIV-1) RNA have been directly quantitated, after an isolation step, in plasma from patients with primary HIV-1 infection by free solution capillary electrophoresis (FSCE) with ultraviolet detection. HIV-1 RNA was detected and quantified at physiological levels by measuring the absorbance by FSCE. All the patients with primary infection showed concentrations in a range of 1.
