Hair cortisol measurement: A systematic review of current practices and a proposed checklist for reporting standards.

Summarising hair cortisol concentration (HCC) methodology may provide much-needed data toward protocol standardisation to maximise future comparability of findings across studies. We searched five electronic databases, reviewing 11,716 publications focused on protocols previously used to measure hair cortisol. Our aim was to determine the frequency with which each procedure was reported in the literature.

Heart rate variability in men with lower urinary tract symptoms: a case-control study.

Purpose: Measurement of heart rate variability (HRV) allows evaluation of autonomic nervous system activity. Decreased HRV is associated with autonomic disbalance, poor health and higher mortality. Our objective is to evaluate the HRV in men with lower urinary tract symptoms (LUTS) through a case-control study.

Development of ELISA Using Recombinant Proteins for the Diagnosis of Infection.

In order to develop a more sensitive and reliable method for detection of serum antibodies against infection in pigs, six recombinant proteins of (P102, P95, P46, P97 like, Lppt, and hypothetical P987) were used for the standardization of an indirect enzyme-linked immunosorbent assay (ELISA). The proteins were evaluated against 50 sera of the specific pathogen-free and 50 sera of pigs with lesions suggestive of infection. The sensitivity was 88%, 86%, 78%, 74%, 66%, and 60% for the proteins P102, P95, P46, P97 like, Lppt, and hypothetical protein P987, respectively.

DNA microarray for forensic intelligence purposes: High-density SNP profiles obtained directly from casework-like samples with and without a DNA purification step.

SNP analyses from a forensic intelligence perspective have proven to be an important tool to restrict the number of suspected offenders and find missing persons. DNA microarray assays have been demonstrated as a potential feature in forensic analysis, like such as forensic genetic genealogy. The objective of this study was to describe the results from DNA microarray assay from saliva samples deposited on a glass surface collected from by a double swab technique, commonly applied in crime scenes.

Health centers in Rio Grande do Sul, Brazil: from implementation to consolidation, 1929-1943.

The article analyzes the introduction, in the late 1920s, and consolidation, in the 1930s, of a public health model in Rio Grande do Sul state based on the health center model conceived in the United States. The genesis of health centers in the United States is discussed, as are two health reforms in Brazil, in 1929 and 1938, proposed by Fernando de Freitas e Castro and José Bonifácio Paranhos da Costa. The investigation draws not only on the literature in the area, but also on primary sources such as legislation, state health reports, and documents produced by the Rockefeller Foundation.
