Effectiveness of intermittent cash incentives to increase step counts.

Only 25% of adults meet both aerobic and strength training recommendations for physical activity. Contingency management interventions have been used to increase physical activity; however, they may be cost prohibitive. Intermittently provided incentives lower costs and are effective for various health behaviors.

The American Society of Addiction Medicine Clinical Practice Guideline Development Methodology.

The American Society of Addiction Medicine (ASAM) has published clinical practice guidelines (CPGs) since 2015. As ASAM's CPG work continues to develop, it maintains an organizational priority to establish rigorous standards for the trustworthy production of these important documents. In keeping with ASAM's mission to define and promote evidence-based best practices in addiction prevention, treatment, and recovery, ASAM has rigorously updated its CPG methodology to be in line with evolving international standards.

The role of priming and memory in rice environmental stress adaptation: Current knowledge and perspectives.

Plant responses to abiotic stresses are dynamic, following the unpredictable changes of physical environmental parameters such as temperature, water and nutrients. Physiological and phenotypical responses to stress are intercalated by periods of recovery. An earlier stress can be remembered as 'stress memory' to mount a response within a generation or transgenerationally.

Jasmonates, gibberellins, and powdery mildew modify cell cycle progression and evoke differential spatiotemporal responses along the barley leaf.

Barley (Hordeum vulgare) is an important cereal crop, and its development, defence, and stress responses are modulated by different hormones including jasmonates (JAs) and the antagonistic gibberellins (GAs). Barley productivity is severely affected by the foliar biotrophic fungal pathogen Blumeria hordei. In this study, primary leaves were used to examine the molecular processes regulating responses to methyl-jasmonate (MeJA) and GA to B.

Novel and Engineered Type II CRISPR Systems from Uncultivated Microbes with Broad Genome Editing Capability.

Type II Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas9 nucleases have been extensively used in biotechnology and therapeutics. However, many applications are not possible owing to the size, targetability, and potential off-target effects associated with currently known systems. In this study, we identified thousands of CRISPR type II effectors by mining an extensive, genome-resolved metagenomics database encompassing hundreds of thousands of microbial genomes.
