Oxytocin: Not "just a female hormone": A very special issue and a very special molecule.

For decades it was believed that oxytocin was "just a female hormone." This was a mistake. In the 21st century it has become clear that oxytocin arose from ancient roots, and acquired dozens of diverse functions throughout the mammalian body.

Structural Enzymology, Phylogenetics, Differentiation, and Symbolic Reflexivity at the Dawn of Biology.

The reflexive translation of symbols in one chemical language to another defined genetics. Yet, the co-linearity of codons and amino acids is so commonplace an idea that few even ask how it arose. Readout is done by two distinct sets of proteins, called aminoacyl-tRNA synthetases (AARS).

Suppression of thrombospondin-1-mediated inflammaging prolongs hematopoietic health span.

Chronic low-grade inflammation observed in older adults, termed inflammaging, is a common feature underlying a multitude of aging-associated maladies including a decline in hematopoietic activity. However, whether suppression of inflammaging can preserve hematopoietic health span remains unclear, in part because of a lack of tools to measure inflammaging within hematopoietic stem cells (HSCs). Here, we identify thrombospondin-1 (Thbs1) as an essential regulator of inflammaging within HSCs.

Tsg101 mimicry of canonical E2 enzymes underlies its role in ubiquitin signaling.

Tsg101 is a highly conserved protein best known as an early-functioning component of cellular ESCRT machinery participating in recognition, sorting, and trafficking of cellular cargo to various intracellular destinations. It shares sequence and structural homology to canonical ubiquitin-conjugating (E2) enzymes and is linked to diverse events regulated by Ub signaling. How it might fulfill these roles is unclear.

Dietary Protein Affects the Growth Response and Tissue Composition of Juvenile Slipper Lobster ().

The effect of different dietary protein levels on apparent feed intake, apparent digestibility, body composition, nutrient retention, and growth efficiency of juvenile slipper lobster () were evaluated for 74 days. Three isoenergetic and isolipidic feeds were formulated with crude protein levels of 445, 490, and 551 g kg DM, designated as P45, P50, and P55, respectively. Lobsters were fed one of these feeds in quadruplicate tanks, with eight lobsters (mean initial wet weight 6.

Twice-Yearly Lenacapavir for HIV Prevention in Men and Gender-Diverse Persons.

Background: Twice-yearly subcutaneous lenacapavir has been shown to be efficacious for prevention of HIV infection in cisgender women. The efficacy of lenacapavir for preexposure prophylaxis (PrEP) in cisgender men, transgender women, transgender men, and gender-nonbinary persons is unclear.

Methods: In this phase 3, double-blind, randomized, active-controlled trial, we randomly assigned participants in a 2:1 ratio to receive subcutaneous lenacapavir every 26 weeks or daily oral emtricitabine-tenofovir disoproxil fumarate (F/TDF).

Molecular heterogeneity in urothelial carcinoma and determinants of clinical benefit to PD-L1 blockade.

Checkpoint inhibitors targeting programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) have revolutionized cancer therapy across many indications including urothelial carcinoma (UC). Because many patients do not benefit, a better understanding of the molecular mechanisms underlying response and resistance is needed to improve outcomes. We profiled tumors from 2,803 UC patients from four late-stage randomized clinical trials evaluating the PD-L1 inhibitor atezolizumab by RNA sequencing (RNA-seq), a targeted DNA panel, immunohistochemistry, and digital pathology.

Deciphering Influence on Social Media: A Comparative Analysis of Influential Account Detection Metrics in the Context of Tobacco Promotion.

Influencer marketing spending in the United States was expected to surpass $6 billion in 2023. This marketing tactic poses a public health threat, as research suggests it has been utilized to undercut decades of public health progress-such as gains made against tobacco use among adolescents. Public health and public opinion researchers need practical tools to capture influential accounts on social media.

Equality of opportunity for timely dementia diagnosis (EQUATED): a qualitative study of how people from minoritised ethnic groups experience the early symptoms of dementia and seek help.

Introduction: People from minoritised ethnic groups are diagnosed with dementia later in the disease. We explored pathways that may determine the timing of diagnoses in a UK ethnically diverse, urban area.

Methods: We conducted 61 semi-structured interviews: 10 community-dwelling older people from minoritised ethnic backgrounds with diagnosed and undiagnosed dementia (mean age = 72 years; males = 5/10), 30 family members (51; 10/30), 16 health or social care professionals (42; 3/15), 3 paid carers and 2 interpreters for people with dementia.

The California collaborative network to promote data driven care and improve outcomes in early psychosis (EPI-CAL) project: rationale, background, design and methodology.

Background: A prolonged first episode of psychosis (FEP) without adequate treatment is a predictor of poor clinical, functional, and health outcomes and significant economic burden. Team-based "coordinated specialty care" (CSC) for early psychosis (EP) has established effectiveness in promoting clinical and functional recovery. However, California's CSC program implementation has been unsystematic and could benefit from standardizing its processes and data collection infrastructure.

Correlation of safety and efficacy of atezolizumab therapy across indications.

Background: The association between safety and efficacy of immune checkpoint inhibitors is known, but the correlation between severity and impact of specific organ involvement by immune-related adverse events (irAE) and cancer outcomes is poorly understood. Most irAEs are mild-to-moderate but severe irAEs may pose clinical management challenges and affect patient outcomes.

Methods: We assessed the association between irAE grade (G) and specific organ involvement with overall survival (OS) in 9,521 patients across 14 studies involving atezolizumab as mono (IO) or with chemo/targeted (C-IO) therapy as compared with chemo/targeted therapy (C) in advanced non-small cell lung, small-cell lung, renal cell, urothelial, and triple-negative breast cancers.

Barriers to and Facilitators of Effective Behavioral Health Crisis Care Services.

Objective: Expanded funding to support care across the crisis continuum is intended to improve behavioral health outcomes. A greater understanding of how to effectively implement and integrate local crisis care systems has been identified as a research and policy priority. The aim of this study was to explore provider perceptions of the barriers and facilitators associated with implementing effective behavioral health crisis services.

The adaptation of a single institution diabetes care platform into a nationally available turnkey solution.

Digital decision support and remote patient monitoring may improve outcomes and efficiency, but rarely scale beyond a single institution. Over the last 5 years, the platform Timely Interventions for Diabetes Excellence (TIDE) has been associated with reduced care provider screen time and improved, equitable type 1 diabetes care and outcomes for 268 patients in a heterogeneous population as part of the Teamwork, Targets, Technology, and Tight Control (4T) Study (NCT03968055, NCT04336969). Previous efforts to deploy TIDE at other institutions continue to face delays.

A genomic database furnishes minimal functional glycyl-tRNA synthetases homologous to other, designed class II urzymes.

The hypothesis that conserved core catalytic sites could represent ancestral aminoacyl-tRNA synthetases (AARS) drove the design of functional TrpRS, LeuRS, and HisRS 'urzymes'. We describe here new urzymes detected in the genomic record of the arctic fox, Vulpes lagopus. They are homologous to the α-subunit of bacterial heterotetrameric Class II glycyl-tRNA synthetase (GlyRS-B) enzymes.

Cytokines in chest tube drainage after pediatric cardiac surgery - Is chylothorax the only phenotype?

Background: Chylothorax after pediatric cardiac surgery is associated with increased morbidity and mortality. Poor understanding exists regarding inflammation within the pleural fluid. Our aim was to determine the relationship between proinflammatory markers and chylothorax.

Analysis of cigar marketing expenditures by product category, placement strategy and geolocation in the USA, from 2017 to 2022.

Significance: The marketing of cigars, little cigars and cigarillos (CLCCs) and cigar wraps is under-regulated and understudied in the USA. To describe strategies CLCC manufacturers and vendors used to advertise their products across marketing channels, we systematically tracked CLCC marketing expenditures from January 2017 to July 2022.

Methods: Using the Kantar Media's Strategy (presently Vivvix) platform, we collected marketing expenditures for 624 CLCC products, vendors, venues, events and media outlets.
