Fourteen asymptomatic normocephalic newborns with confirmed congenital Zika infection were investigated. All newborns presented Zika virus (ZIKV) positivity on reverse transcriptase polymerase chain reaction. Following ZIKV-specific NS5 gene fragment sequencing in one child, phylogenetic analysis revealed that this isolate belonged to the Asian genotype, and clustered closely with other sequences previously isolated in north-east and northern regions of Brazil.

Article Synopsis
- Salvador was significantly impacted during the 2015 Zika virus outbreak, prompting a study involving parturients (pregnant women) and their newborns.
- The study found that 6.9% of parturients tested positive for Zika virus (ZIKV), with higher rates of exposure to dengue (DENV) and Chikungunya (CHIKV) reflected in antibody tests.
- The results emphasized the importance of prenatal and neonatal screening for ZIKV and CHIKV due to the occurrence of congenital infections observed in 16.5% of newborns for ZIKV and 13% for CHIKV.
(1) Background: We investigated the effects of 28 days of beta-alanine (β-alanine) supplementation on the acute interference effect of high-intensity intermittent exercise (HIIE) on lower-body resistance exercise performance, body composition, and strength when combined with a resistance training program. (2) Methods: Twenty-two males were randomized into: β-alanine supplementation (6.4 g/day) or placebo (6.

Although AIDS-related malignancies are a common feature of late-stage disease, patients under successful antiretroviral therapy also have an increased risk for development of non-AIDS malignancies.
Objective: To compare the frequency and characteristics of adults HIV-infected patients and general population who died of malignancies in Bahia, Brazil from January 2000 to December 2010.
Article Synopsis
- Biogas production is a promising renewable energy source, and determining the biomethane potential (BMP) of various organic materials is crucial for designing anaerobic digesters.
- A workshop in June 2015 in Switzerland brought together over 40 participants from 30 laboratories to address the inconsistencies in BMP test results and agree on common validation methods.
- The paper outlines essential validation elements for BMP tests, including specific testing protocols, the importance of control assays, and recommendations for factors affecting BMP results to improve reliability and reproducibility.
