Effect of exercise-conditioned human serum on the viability of cancer cell cultures: A systematic review and meta-analysis.

Numerous epidemiological studies have shown the existence of a relationship between exercise and reduced risk of different types of cancer. In vitro studies have identified a direct effect of exercise-conditioned human serum on cancer cell lines of the lung, breast, prostate, and colon. The aim of this systematic review with meta-analysis (SRM) was to estimate the magnitude of the effect that exercise-conditioned human serum produced on the viability of cancer cell cultures.

Objectively Measured Sedentary Behavior and Physical Fitness in Adults: A Systematic Review and Meta-Analysis.

: Sedentary behavior has been considered an independent risk factor to health. The aim of this systematic review and meta-analysis was to examine associations between objectively measured sedentary time and physical fitness components in healthy adults. : Four electronic databases (Web of Science, Scopus, Pubmed and Sport Discus) were searched (up to 20 September 2020) to retrieve studies on healthy adults which used observational, cohort and cross-sectional designs.

[Streptomyces rimosus aminoglycoside-3'-phosphotransferase VIII: comparisons with aminoglycoside-3'-phosphotransferases of aminoglycoside-producing strains with eukaryotic protein kinases].

The nucleotide sequence was established for the aphVIII aminoglycoside phosphotransferase gene of an oxytetracycline-producing Streptomyces rimosus strain. The gene is 804 bp in size and possibly codes for APHVIII of 267 residues. Heterologous expression of aphVIII was studied in Escherichia coli and Chlamydomonas reinhardtii.
