Posttraumatic Stress Symptoms and Posttraumatic Cognitions in the Wake of the Death of Michael Brown.

On August 9, 2014, Michael Brown was shot and killed by police officer Darren Wilson in Ferguson Missouri, sparking protests and civil unrest. Three studies have yielded inconsistent findings regarding the presence of posttraumatic stress symptoms (PTSSs) in the aftermath of the unrest in Ferguson. Additional work is needed to understand how exposure to community-level stressors may correspond with trauma-related outcomes, as well as accounting for knowledge of, and engagement in the events.

Phosphatidic Acid Signaling in Modulating Plant Reproduction and Architecture.

Phosphatidic acid (PA) is an important class of signaling lipids involved in various biological processes in plants. Functional characterization of the mutants of PA's metabolizing enzymes coupled with lipidomics and protein-lipid interaction analyses have revealed that PA signaling is involved in plant response to biotic and abiotic stress. Moreover, PA and its metabolizing enzymes have been found to affect various reproductive steps, including gametogenesis, pollen tube growth, self-incompatibility, haploid embryo formation, embryogenesis, and seed development.

Improving first responders' perceptions of overdose events and survivors through tailored occupational health-focused training co-facilitated by overdose survivors.

Background: First responders (law enforcement officers, emergency medical services, and firefighters) frequently interact with people who use drugs (PWUD). Based on the nature and outcomes of such encounters, these interactions have the potential either to reduce harm, or perpetuate it. Given increased funding and attention for first responder-led interventions involving PWUD, we must identify the most critical training for improving negative beliefs about these interventions and populations.

Adverse Childhood Experiences, Racial Discrimination, and Internalizing Problems among Asian Adolescents.

The purpose of the current research study was to examine the relationship among Adverse Childhood Experiences (ACEs), racial discrimination, and internalizing problems (i.e., anxiety, depression) among Asian adolescents in the US.

Recent Catalytic Applications of Ferrocene and Ferrocenium Cations in the Syntheses of Organic Compounds.

Ferrocene and its oxidized counterpart, the ferrocenium cation, represent a fascinating class of organometallic compounds with broad utility across various fields, including organic synthesis, pharmaceuticals, and materials science. Over the years, ferrocene, ferrocenium cations, and their derivatives have also gained prominence for their versatility in catalytic processes. This review article offers an overview of the research of the last decade into ferrocene- and ferrocenium-based catalysis.

Peritraumatic C-reactive protein levels predict pain outcomes following traumatic stress exposure in a sex-dependent manner.

Background: Chronic pain following traumatic stress exposure (TSE) is common. Increasing evidence suggests inflammatory/immune mechanisms are induced by TSE, play a key role in the recovery process versus development of post-TSE chronic pain, and are sex specific. In this study, we tested the hypothesis that the inflammatory marker C-reactive protein (CRP) is associated with chronic pain after TSE in a sex-specific manner.

Co-mast: Harmonized seed production data for woody plants across US long-term research sites.

Plants display a range of temporal patterns of inter-annual reproduction, from relatively constant seed production to "mast seeding," the synchronized and highly variable interannual seed production of plants within a population. Previous efforts have compiled global records of seed production in long-lived plants to gain insight into seed production, forest and animal population dynamics, and the effects of global change on masting. Existing datasets focus on seed production dynamics at the population scale but are limited in their ability to examine community-level mast seeding dynamics across different plant species at the continental scale.

Gene expression signatures between Limia perugiae (Poeciliidae) populations from freshwater and hypersaline habitats, with comparisons to other teleosts.

Salinity gradients act as strong environmental barriers that limit the distribution of aquatic organisms. Changes in gene expression associated with transitions between freshwater and saltwater environments can provide insights into organismal responses to variation in salinity. We used RNA-sequencing (RNA-seq) to investigate genome-wide variation in gene expression between a hypersaline population and a freshwater population of the livebearing fish species Limia perugiae (Poeciliidae).

Cyclophostin and Cyclipostins analogues counteract macrolide-induced resistance mediated by erm(41) in Mycobacterium abscessus.

Background: Mycobacterium abscessus is an emerging pathogen causing severe pulmonary infections, particularly in individuals with underlying conditions, such as cystic fibrosis or chronic obstructive pulmonary disease. Macrolides, such as clarithromycin (CLR) or azithromycin (AZM), represent the cornerstone of antibiotherapy against the M. abscessus species.

A Comprehensive Model of Community Violence Exposure Outcomes Using an Ecological Systems Framework.

Community violence (CV) is associated with negative psychosocial outcomes, such as posttraumatic stress symptoms (PTSS) and anger; however, many individuals also exhibit resilience. Considering the multifinality of outcomes following CV and guided by Bronfenbrenner's ecological systems framework, the current study sought to examine individual, microsystem, and exosystem level factors in relation to PTSS, anger, and resilience. Participants were 536 emerging adults ( = 20.

Exploring Facets of Trust and Religiosity in Organ Donation for Black and White Americans.

This study examines how Black and White Americans perceive two facets of trust (trust in medical doctor and trust in medical care for racial group) and two facets of religiosity (religious service attendance and religious norms regarding organ donation) in relation to the topic of organ donation. Two hundred and one participants (N = 201) were surveyed across the United States using the Qualtrics survey company. Bivariate analyses found donor status was not related to religious service attendance (r = - .

The establishment of the anther somatic niche with single-cell sequencing.

The anther is the developmental housing of pollen and therefore the male gametes of flowering plants. The meiotic cells from which pollen are derived must differentiate de novo from somatic anther cells and synchronously develop with the rest of the anther. Anthropogenic control over another development has become crucial for global agriculture so as to maintain inbred lines and generate hybrid seeds of many crops.

Why Is It Too Cold? Towards a Mechanistic Understanding of Cold-Water Pollution Effects on Recruitment of an Imperiled Warmwater Fish.

Environmental temperature shapes the ontogeny of ectotherms by influencing rates of growth and development which can be key determinants of survival. Whereas the escalating impacts of water management on freshwater ecosystems is well documented, the effects of cold-water releases from dams-which can alter downstream temperatures-remains relatively underexplored but may present novel challenges to endemic ectotherms. Specifically, little is known about how thermal depressions reshape phenotypic and genetic patterns during larval metamorphosis for fishes that evolved in warmwater systems.
