Facet-controlled electrosynthesis of nanoparticles by combinatorial screening in scanning electrochemical cell microscopy.

Controlled synthesis of faceted nanoparticles on surfaces without explicit use of ligands has gained attention due to their promising applications in electrocatalysis and chemical sensing. Electrodeposition is a desirable method; however, precise control over their size, spatial distribution, and morphology requires extensive optimization. Here, we report the spatially resolved synthesis of shape-controlled Pt nanoparticles and fast screening of synthesis conditions in scanning electrochemical cell microscopy (SECCM) with pulse potentials.

This qualitative study explores health care providers' perspectives on the oral PrEP care continuum for adults, emphasizing barriers, facilitators, and missed opportunities in PrEP implementation.

Age-invariant genes: multi-tissue identification and characterization of murine reference genes.

Studies of the aging transcriptome focus on genes that change with age. But what can we learn from age-invariant genes-those that remain unchanged throughout the aging process? These genes also have a practical application: they can serve as reference genes in expression studies. Reference genes have mostly been identified and validated in young organisms, and no systematic investigation has been done across the lifespan.

LAPS SA: Measuring Attachment to Dogs and Cats Among South American Countries.

Human biological and cultural evolution is tied to the relationships established with other animals. Attachment is one of the mechanisms established between dogs/cats and humans and allows the generation of affective bonds and close proximity. Many instruments have been used to study attachment of people to their dogs/cats, such as the Lexington Attachment to Pets Scale (LAPS).

Fear conditioning modulates the intrinsic excitability of ventral hippocampal CA1 neurons in male rats.

The hippocampus has a known role in learning and memory, with the ventral subregion supporting many learning tasks involving affective responding, including fear conditioning. Altered neuronal intrinsic excitability reflects experience-dependent plasticity that supports learning-related behavioral changes. Such changes have previously been observed in the dorsal hippocampus following fear conditioning, but little work has examined the effect of fear conditioning on ventral hippocampal intrinsic plasticity.

The meninges host a distinct compartment of regulatory T cells that preserves brain homeostasis.

Our understanding of the meningeal immune system has recently burgeoned, particularly regarding how innate and adaptive effector cells are mobilized to meet brain challenges. However, information on how meningeal immunocytes guard brain homeostasis in healthy individuals remains limited. This study highlights the heterogeneous, polyfunctional regulatory T cell (T) compartment in the meninges.

Understanding viral non-suppression among people with HIV engaged in a mobile health program.

By consistently taking medication, people with HIV (PWH) can attain viral suppression, improving their health and reducing transmission risk. PositiveLinks (PL) is a clinic-deployed mobile platform designed to improve engagement in care for PWH by enabling them to track their medications, connect with peers, and communicate with providers. This project investigated the experience of PL users who had recent periods of viral non-suppression to understand how these high-risk episodes can be predicted and prevented.

Sexual Dimorphism in the Downregulation of Extracellular Matrix Genes Contribute to Aortic Structural Stiffness in Female Mice.

The contribution of sex hormones to cardiovascular disease, including arterial stiffness, is established; however, the role of sex chromosome interaction with sex hormones, particularly in women, is lagging. Arterial structural stiffness depends on the intrinsic properties and transmural wall geometry that comprise a network of cells and extracellular matrix (ECM) proteins expressed in a sex-dependent manner. In this study, we used four-core genotype (FCG) mice to determine the relative contribution of sex hormones versus sex chromosomes or their interaction with arterial structural stiffness.

Leadership development programs in healthcare organizations: What they are and how to assemble them.

In the highly competitive, perennially-changing healthcare industry, management prowess is vitally needed by those in positions of authority, but in isolation it is insufficient for delivering optimal results. Instead, management proficiencies must be complemented by leadership skills which amplify managerial efforts and outcomes. One avenue for building leadership acumen in healthcare organizations involves the establishment of leadership development programs.

The leadership expectations statement: A simple tool for enhancing leadership in healthcare organizations.

Healthcare organizations are reliant on cadres of managers to oversee operations, ensuring the delivery of excellent patient care and accomplishment of institutional missions. These managers obviously must be well versed in the principles of management, but they also must be proficient in leadership. As leadership can take many different forms, healthcare organizations must take care in their associated leadership development efforts to ensure that they have a firm grasp on the precise leadership qualities needed within their given organizations.

Evaluating leadership development programs in healthcare organizations: A profile from practice.

To enhance leadership acumen and intelligence among the managerial ranks, many healthcare organizations establish leadership development programs. Doing so makes perfect sense as the caliber of leadership within health and medical institutions profoundly influences all aspects of operation. Although leadership development programs are very capable mechanisms for advancing the state of leadership within healthcare organizations, a notable enhancement-evaluation-is needed to maximize their potential.

The methods used to process tongue swabs for testing in the World Health Organization-recommended Xpert MTB/RIF Ultra (Xpert Ultra) assay vary greatly. Here, we aimed to identify the optimal tongue swab processing for Xpert Ultra testing.

Global Impact of Mass Vaccination Campaigns on Circulating Type 2 Vaccine-Derived Poliovirus Outbreaks: An Interrupted Time-Series Analysis.

Background: Between 2016 and 2023, 3248 cases of circulating vaccine-derived type 2 poliomyelitis (cVDPV2) were reported globally and supplementary immunization activities (SIAs) with monovalent type 2 oral poliovirus vaccine (mOPV2) and novel type 2 oral poliovirus vaccine (nOPV2) targeted an estimated 356 and 525 million children, respectively. This analysis estimates the community-level impact of nOPV2 relative to mOPV2 SIAs.

Methods: We fitted interrupted time-series regressions to surveillance data between January 2016 and November 2023 to estimate the impact of nOPV2 and mOPV2 SIAs on cVDPV2 poliomyelitis incidence and prevalence in environmental surveillance across 37 countries, directly comparing the impact of SIAs in 13 countries where both vaccines were used.

Biodiversity within phytoplankton-associated microbiomes regulates host physiology, host community ecology, and nutrient cycling.

Unlabelled: Biological diversity is declining across the tree of life, including among prokaryotes. With the increasing awareness of host-associated microbes as potential regulators of eukaryotic host physiology, behavior, and ecology, it is important to understand the implications of declining diversity within host microbiomes on host fitness, ecology, and ecosystem function. We used phytoplankton and their associated environmental microbiomes as model systems to test the independent and interactive effects of declining microbiome diversity with and without other stressors often caused by human activity-elevated temperature and altered nutrient availability.

Characterization of spike S1/S2 processing and entry pathways of lentiviral pseudoviruses bearing seasonal human coronaviruses NL63, 229E, and HKU1 spikes.

Although much has been learned about the entry mechanism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), many details of the entry mechanisms of seasonal human coronaviruses (HCoVs) remain less well understood. In the present study, we used 293T cell lines stably expressing angiotensin converting enzyme (ACE2), aminopeptidase N (APN), or transmembrane serine protease 2 (TMPRSS2), which support high-level transduction of lentiviral pseudoviruses bearing spike proteins of seasonal HCoVs, HCoV-NL63, -229E, or -HKU1, respectively, to compare spike processing and virus entry pathways among these viruses. Our results showed that the entry of HCoV-NL63, -229E, and -HKU1 pseudoviruses into cells is sensitive to endosomal acidification inhibitors (chloroquine and NHCl), indicating entry via the endocytosis route.
