[Effect of an intervention in physical education classes on the reduction of sedentary behavior in adolescents].

This study aimed to analyze the effect of different intervention strategies in physical education classes on the reduction of sedentary time. This is a randomized, school-based intervention with factorial characteristics, carried out with freshmen high school students from 11 full-time schools, allocated in three intervention situations: (A) schools with two extra physical education classes per week; (B) schools with training and engagement actions for physical education teachers; (C) Schools with both A and B strategies; and (D) a group of control schools. Accelerometry was used to obtain the effect measure of the main outcome (sedentary behavior).

The contamination effect on recognition memory: adding evidence of an adaptive mnemonic tuning.

Previous research has revealed enhanced free recall for neutral items previously associated with disease-causing agents, compared to when they are associated with neutral information; this has been termed the contamination effect. However, it remains unknown whether this effect extends to recognition memory and, if so, on what processes it would rely (i.e.

Selection of GABA-Producing Lactic Acid Bacteria Strains by Polymerase Chain Reaction Using Novel B and C Multispecies Primers for the Development of New Functional Foods.

Gamma-aminobutyric acid (GABA) has been attributed to health-promoting properties and has received attention from the food industry as an attractive bioactive compound for the development of functional foods. Some lactic acid bacteria (LAB) produce GABA through a glutamate decarboxylase encoded by B and a glutamate/GABA antiporter encoded by C. In this study, we develop a molecular screening method based on a polymerase chain reaction able to detect those genes in different LAB species through the use of novel multispecies primers.

Preferential Genetic Pathways Lead to Relapses in Adult B-Cell Acute Lymphoblastic Leukemia.

Adult B-cell acute lymphoblastic leukemia (B-ALL) is characterized by genetic heterogeneity and a high relapse rate, affecting over 40% of adults. However, the mechanisms leading to relapse in adults are poorly understood. Forty-four adult B-ALL patients were studied at both diagnosis and relapse by next-generation sequencing (NGS).
