Couple-Oriented Interventions for Mental Health: A Scoping Review.

The purpose of this research was to systematically examine and collate evidence on couple-oriented interventions for mental health to identify trends in the literature, review research strategies, and suggest directions for future research. A systematic search included studies relating to couple-oriented interventions for preventing mental disorders and/or promoting mental health. We identified a total of 52 studies, which included 55 articles.

Shoulder Muscle Activity While Swimming in Different Wetsuits and Across Different Paces.

A triathlon wetsuit is an important piece of equipment during the swim portion of the triathlon for the benefits of thermoregulation and additional buoyancy. However, a lack of knowledge exists about whether or not shoulder muscle activity is influenced by wearing a wetsuit. The purpose of this study was to determine if there were changes in shoulder muscle activity during front crawl with four different wetsuit conditions: Full sleeve (FSW), Sleeveless (SLW), Buoyancy shorts (BS), No wetsuit (NWS) in three different subjective swimming paces (slow, medium, and fast).

Couple- or family-oriented interventions and outcomes for preventing mental health problems and promoting mental health: a scoping review protocol.

Objective: The objective of this scoping review is to map the literature describing couple- and family-oriented interventions and outcomes to prevent mental health problems and promote mental health.

Introduction: Literature involving couple- and family-focused mental health interventions has gained increased attention over the past two decades, yet little is known about the efficacy of these interventions for promoting mental health and preventing mental disorders. Despite recognition that the most sustainable method for reducing the increasing burden of mental disorders is primary prevention, there has been no systematic investigation of relevant couple- and family-focused interventions.

Regulation of Escherichia coli RNase III activity.

Bacterial cells respond to changes in the environment by adjusting their physiological reactions. In cascades of cellular responses to stresses of various origins, rapid modulation of RNA function is known to be an effective biochemical adaptation. Among many factors affecting RNA function, RNase III, a member of the phylogenetically highly conserved endoribonuclease III family, plays a key role in posttranscriptional regulatory pathways in Escherichia coli.

Fine-tuning of single-molecule conductance by tweaking both electronic structure and conformation of side substituents.

Herein, we describe a method to fine-tune the conductivity of single-molecule wires by employing a combination of chemical composition and geometrical modifications of multiple phenyl side groups as conductance modulators embedded along the main axis of the electronic pathway. We have measured the single-molecule conductivity of a novel series of phenyl-substituted carotenoid wires whose conductivity can be tuned with high precision over an order of magnitude range by modulating both the electron-donating character of the phenyl substituent and its dihedral angle. It is demonstrated that the electronic communication between the phenyl side groups and the molecular wire is maximized when the phenyl groups are twisted closer to the plane of the conjugated molecular wire.

Stability of the osmoregulated promoter-derived proP mRNA is posttranscriptionally regulated by RNase III in Escherichia coli.

Unlabelled: The enzymatic activity of Escherichia coli endo-RNase III determines the stability of a subgroup of mRNA species, including bdm, betT, and proU, whose protein products are associated with the cellular response to osmotic stress. Here, we report that the stability of proP mRNA, which encodes a transporter of osmoprotectants, is controlled by RNase III in response to osmotic stress. We observed that steady-state levels of proP mRNA and ProP protein are inversely correlated with cellular RNase III activity and, in turn, affect the proline uptake capacity of the cell.

Two tandem RNase III cleavage sites determine betT mRNA stability in response to osmotic stress in Escherichia coli.

While identifying genes regulated by ribonuclease III (RNase III) in Escherichia coli, we observed that steady-state levels of betT mRNA, which encodes a transporter mediating the influx of choline, are dependent on cellular concentrations of RNase III. In the present study, we also observed that steady-state levels of betT mRNA are dependent on RNase III activity upon exposure to osmotic stress, indicating the presence of cis-acting elements controlled by RNase III in betT mRNA. Primer extension analyses of betT mRNA revealed two tandem RNase III cleavage sites in its stem-loop region, which were biochemically confirmed via in vitro cleavage assays.

RNase III controls mltD mRNA degradation in Escherichia coli.

RNase III is a double-stranded RNA-specific endoribonuclease that processes and degrades numerous mRNA molecules in Escherichia coli. A previous genome-wide analysis of E. coli transcripts showed that steady-state levels of mltD mRNA, which encodes membrane-bound lytic murein transglycosylase D, was most affected by changes in cellular concentration of RNase III.

Functional conservation of RNase III-like enzymes: studies on a Vibrio vulnificus ortholog of Escherichia coli RNase III.

Bacterial ribonuclease III (RNase III) belongs to the RNase III enzyme family, which plays a pivotal role in controlling mRNA stability and RNA processing in both prokaryotes and eukaryotes. In the Vibrio vulnificus genome, one open reading frame encodes a protein homologous to E. coli RNase III, designated Vv-RNase III, which has 77.

RNase III controls the degradation of corA mRNA in Escherichia coli.

In Escherichia coli, the corA gene encodes a transporter that mediates the influx of Co(2+), Mg(2+), and Ni(2+) into the cell. During the course of experiments aimed at identifying RNase III-dependent genes in E. coli, we observed that steady-state levels of corA mRNA as well as the degree of cobalt influx into the cell were dependent on cellular concentrations of RNase III.
