An angiotensin converting enzyme homolog is required for volatile pheromone detection, odorant binding protein secretion and normal courtship behavior in Drosophila melanogaster.

In many arthropods, including insects responsible for transmission of human diseases, behaviors that include mating, aggregation, and aggression are triggered by detection of pheromones. Extracellular odorant binding proteins are critical for pheromone detection in many insects and are secreted into the fluid bathing the olfactory neuron dendrites. In Drosophila melanogaster, the odorant binding protein LUSH is essential for normal sensitivity to the volatile sex pheromone, 11-cis vaccenyl acetate (cVA).

Validation of the Short Form of the Mood Instability Questionnaire-Trait (MIQ-T-SF) in the Korean General Population.

Membrane Ruffling is a Mechanosensor of Extracellular Fluid Viscosity.

Cell behaviour is affected by the physical forces and mechanical properties of the cells and of their microenvironment. The viscosity of extracellular fluid - a component of the cellular microenvironment - can vary by orders of magnitude, but its effect on cell behaviour remains largely unexplored. Using bio-compatible polymers to increase the viscosity of the culture medium, we characterize how viscosity affects cell behaviour.

A tubulin-binding protein that preferentially binds to GDP-tubulin and promotes GTP exchange.

α- and β-tubulin form heterodimers, with GTPase activity, that assemble into microtubules. Like other GTPases, the nucleotide-bound state of tubulin heterodimers controls whether the molecules are in a biologically active or inactive state. While α-tubulin in the heterodimer is constitutively bound to GTP, β-tubulin can be bound to either GDP (GDP-tubulin) or GTP (GTP-tubulin).

Membrane compression by synaptic vesicle exocytosis triggers ultrafast endocytosis.

Compensatory endocytosis keeps the membrane surface area of secretory cells constant following exocytosis. At chemical synapses, clathrin-independent ultrafast endocytosis maintains such homeostasis. This endocytic pathway is temporally and spatially coupled to exocytosis; it initiates within 50 ms at the region immediately next to the active zone where vesicles fuse.

Expanding the phenotype of DNMT3A as a cause a congenital myopathy with rhabdomyolysis.

Pathogenic variants in DNMT3A are most commonly associated with Tatton-Brown-Rahman Syndrome (TBRS), but includes other phenotypes such as Heyn-Sproul-Jackson syndrome and acute myeloid leukemia (AML). We describe a patient presenting to the neuromuscular clinic with a de novo missense variant in DNMT3A where the striking clinical feature is that of a congenital myopathy with associated episodes of rhabdomyolysis, severe myalgias and chest pain along with phenotypic features associated with TBRS. Muscle biopsy showed minor myopathic features and cardiac investigations revealed mildly impaired bi-ventricular systolic function.

Emotion Regulation Difficulties and Relationship Satisfaction in Adolescent Couples: The Role of Conflict Resolution Strategies.

Emotion regulation difficulties have been found to predict relationship satisfaction in adult samples, yet little is known with regards to the processes explaining these associations in adolescent dating relationships. Furthermore, among the available literature, most studies only consider one romantic partner. To address this gap, this study used a dyadic approach and considered the role of conflict resolution strategies (i.

Causes and risk factors of death among people who inject drugs in Indonesia, Ukraine and Vietnam: findings from HPTN 074 randomized trial.

Introduction: The HIV Prevention Trials Network (HPTN) 074 study demonstrated a positive effect of an integrated systems navigation and psychosocial counseling intervention on HIV treatment initiation, viral suppression, medication assisted treatment (MAT) enrollment, and risk of death among people who inject drugs (PWID). In this sub-study, we analyzed the incidence, causes, and predictors of death among HIV-infected and uninfected participants.

Methods: The HPTN 074 randomized clinical trial was conducted in Indonesia, Ukraine, and Vietnam.

Phytochemical constituents from the rhizomes of Wall. ex Baker and their acetylcholinesterase inhibitory activity.

Phytochemical study on the rhizomes of led to the isolation of twenty-three compounds including six phenolic glycosides (-), thirteen flavones (-), and five phenolic compounds (-). Of these, the new compounds were determined to be 2,4-dihydroxy-6-methoxyacetophenone-2D-apiofuranosyl-(1→6)D-glucopyranoside (), 2-hydroxy-4-propionyl-phenyl D-glucopyranoside (), and 4-hydroxy-3,5-dimethoxyacetophenone 8-L-rhamnopyranosyl-(1→6)D-glucopyranoside () and named as kaempanosides A-C, respectively. Their chemical structures were established based on HR-ESI-MS, 1D and 2D NMR spectra.

Effect of Home-based Self-administered Transcranial Direct Stimulation in Patients with Mild to Moderate Major Depressive Disorder: A Single-arm, Multicentral Trial.

Objective: Although the effects and safety of transcranial direct current stimulation (tDCS) treatment in depressive patients are largely investigated, whether the self-administration of tDCS treatment at patient's home is comparable to clinic-based treatment is still unknown.

Methods: In this single-arm, multi-center clinical trial, 61 patients with mild to moderate major depressive disorder were enrolled. tDCS treatment was delivered at the patient's home once a day, 5 to 7 times a week for 6 weeks, and each session lasted for 30 minutes.

The Mediating Effect of Changes in Depression Symptoms on the Relationship between Health-Related Quality of Life and Alcohol Consumption: Findings from a Longitudinal Study among Men Living with HIV in India.

Heavy alcohol use is negatively affecting antiretroviral therapy adherence, mental health and health-related quality of life among people living with HIV (PLWH). This paper aims to test the mediation model examining whether changes in depression symptoms mediate in the relationship between health-related quality of life and alcohol use among male PLWH who consume alcohol in India. The study is guided by the stress-coping model, which posits that individuals facing stress may turn to maladaptive coping mechanisms such as alcohol use to alleviate their distress, which includes depression and a low health-related quality of life due to various physical, psychological, and social factors associated with the HIV infection.
