US Army Accession and Retention Standards: Impact on Obesity and Medical Readiness.

Introduction: Military body fat standards were implemented in the 1980s to prevent obesity and associated poor military readiness. In the past 2 decades, enforcement of existing Army body composition standards has been eroded by the steady increase in national obesity rates, the demand for new recruits especially during the 2007 surge in Iraq, and the COVID epidemic in 2020. The diminishing qualified recruit pool puts a new focus on accession standards.

CCL2/CCR2 Signalling in Mesenchymal Stem/Progenitor Cell Recruitment and Fracture Healing in Mice.

Macrophage efferocytosis (clearance of apoptotic cells) is crucial for tissue homeostasis and wound repair, where macrophages secrete factors that promote resolution of inflammation and regenerative signalling. This study examined the role of efferocytic macrophage-associated CCL2 secretion, its influence on mesenchymal stem/progenitor cell (MSPC) chemotaxis, and in vivo cell recruitment using Ccr2 (KO) mice with disrupted CCL2 receptor signalling in two regenerative models: ossicle implants and ulnar stress fractures. Single cell RNA sequencing and PCR validation indicated that efferocytosis of various apoptotic cells at bone injury sites (osteoblasts, pre-osteoblasts, MSPC) upregulated CCL2.

Evolution of NAC transcription factors from early land plants to domesticated crops.

NAC [NO APICAL MERISTEM (NAM), ARABIDOPSIS TRANSCRIPTION ACTIVATOR FACTOR 1/2 (ATAF1/2), and CUP-SHAPED COTYLEDON (CUC2)] transcription factors are key regulators of plant growth, development, and stress responses but were also crucial players during land plant adaptation and crop domestication. Using representative members of green algae, bryophytes, lycophytes, gymnosperms, and angiosperms, we expanded the evolutionary history of NAC transcription factors to unveil the relationships among members of this gene family. We found a massive increase in the number of NAC transcription factors from green algae to lycophytes and an even larger increase in flowering plants.

Microplastics inhibit the decomposition of soil organic matter by adult darkling beetles (Coleoptera: Tenebrionidae).

Microplastics (MPs) are a growing problem worldwide. Soils are long-term storage sinks of MPs because of the many pathways they enter the soil and their long degradation period. Knowing how MPs influence soil organisms, the effects of organisms on the fate of MPs, and what this means for soil additions, losses, transformations, and translocations is paramount.

Estimating optimal temperature conditions for growth, development, and reproduction of Tenebrio molitor (Coleoptera: Tenebrionidae).

The yellow mealworm, Tenebrio molitor L., is one of the most important industrialized insects worldwide. As a poikilotherm, T.

Host plant selection and performance of ambrosia beetles in flood-stressed versus ethanol-injected trees provide implications for management strategies.

Ambrosia beetles (Curculionidae: Scolytinae and Platypodinae) are fungus-farming woodborers that can cause damage to the trees they colonize. Some of these beetles target stressed plants that emit ethanol, and management strategies have proposed using ethanol-injected trees as trap trees to monitor or divert dispersing adult females away from valuable crops. In this study, we used container-grown trees from 8 species to compare the effect of ethanol injection versus flooding on ambrosia beetle host selection and colonization success.

Climate matching models for Ceratapion basicorne (Coleoptera: Apionidae), a biocontrol agent of yellow starthistle.

Ceratapion basicorne (Illiger) (Coleoptera: Apionidae), a weevil native to Europe and western Asia, shows promise for enhancing the control of yellow starthistle (Centaurea solstitialis L.), an invasive annual forb in the western United States. However, a paucity of data on this biocontrol agent's environmental constraints has made it difficult to assess the suitability of potential release locations.

Anticipated Responses to Genetic Testing for Alzheimer's Disease Susceptibility among Latinos in Northern Manhattan.

Alzheimer's disease (AD) is a debilitating neurodegenerative illness that has become a growing concern for older adults. As such, apolipoprotein E (APOE) genetic testing has become more commonly used to identify individuals' susceptibility to AD. An underrepresented population in AD research, Latinos will be disproportionately affected by AD in the coming decades.

Dual-layer dual-energy CT characterization of thrombus composition in acute pulmonary embolism and chronic thromboembolic pulmonary hypertension.

To evaluate dual-layer dual-energy computed tomography (dlDECT)-based characterization of thrombus composition for differentiation of acute pulmonary embolism (PE) and chronic thromboembolic pulmonary hypertension (CTEPH). This retrospective single center cohort study included 49 patients with acute PE and 33 patients with CTEPH who underwent CT pulmonary angiography on a dlDECT from 06/2016 to 06/2022. Conventional images), material specific images (virtual non-contrast [VNC], iodine density overlay [IDO], electron density [ED]), and virtual monoenergetic images (VMI) were analyzed.

Intraepithelial ILC1-Like NK Cells Increase Lymphocyte Infiltration into the Tumor Microenvironment via the CXCL10 Axis.

Intraepithelial type 1 innate lymphoid cells (ieILC1s) are tissue-resident lymphocytes in the microenvironment of head and neck squamous cell carcinoma. Here, we evaluate how these cells influence T-cell trafficking to tumors. We generated cytotoxic ieILC1-like cells from natural killer (NK) cells in vitro.

Using community organizing to build a system of care: A mixed methods evaluation.

The purpose of this study was to utilize mixed methods to evaluate the initial implementation of a system of care (SOC) developed and implemented from a community organizing framework. Surveys were conducted with partners (navigators, community partners, parents) to examine changes pre- and post-implementation of the SOC. Surveys assessed care coordination, effectiveness of communication across organizations, quality of services and relationships, barriers, health-related stressors, and distrust.

Antiracist activism for immigrant rights and healthy coping: Initial evidence for a community-based framework.

Racist and xenophobic policies in the United States (e.g., family separations and lack of access to protected immigration statuses for undocumented immigrants) have historically excluded immigrants of color from accessing full civil rights, thus contributing to widening racial inequities in the US.

Navigating immigrant paths: A case study of unaccompanied youth in foster care.

Understanding the experiences of unaccompanied youths in refugee foster care is important to tailor such systems to support the complex needs and desires of these youth. This instrumental case study sought to understand how a cohort of unaccompanied refugee youth experience refugee foster care as they navigate the "in-betweenness" of adolescence. Eight youth (ages 17-21) from Guatemala and Honduras, nine foster parents, and two staff were interviewed.

Closing the loops: chromatin loop dynamics after DNA damage.

Chromatin is a dynamic polymer in constant motion. These motions are heterogeneous between cells and within individual cell nuclei and are profoundly altered in response to DNA damage. The shifts in chromatin motions following genomic insults depend on the temporal and physical scales considered.

Pre-HIV α4β7hi CD4+ T cells and HIV risk among heterosexual individuals in Africa.

Background: CD4+ T cells expressing α4β7 are optimal targets for HIV infections, with higher pre-HIV α4β7hi expression linked to increased HIV acquisition and progression in South African women. However, similar associations were not observed in men who have sex with men (MSM) or people who inject drugs (PWID) in the Americas, indicating need for further research.

Methods: This retrospective case-control study enrolled heterosexual men and women from South Africa (HIV Vaccine Trials Network; HVTN 503) and East Africa (Partners Pre-Exposure Prophylaxis/Couples' Observational Study; PP/COS), quantifying α4β7 expression on CD4+ T cells as a predictor of subsequent HIV risk using flow cytometry analyses.

Distressing Aspects of Elder Abuse Victimization: Perspective of Survivors.

Objectives: Our understanding of elder abuse (EA) phenomena has largely been shaped from the perspective of researchers and professionals whose conceptualizations often differ from the perceptions of older adults who experience mistreatment. This study sought to understand the most distressing aspects of EA victimization from the perspective of survivors.

Methods: Using a descriptive phenomenological approach, individual interviews were conducted with a diverse sample ( = 32) of EA survivors, recruited from EA support and Adult Protective Services programs in New York City and Los Angeles.

In situ characterization of amine-forming enzymes shows altered oligomeric state.

Enzyme stability can be measured in a number of ways, including melting temperature, activity retention, and size analysis. However, these measurements are often conducted in an idealized storage buffer and not in the relevant enzymatic reaction media. Particularly for reactions that occur in alkaline, volatile, and high ionic strength media, typical analyses using differential scanning calorimetry, light scattering, and sodium dodecyl-sulfate polyacrylamide gel electrophoresis are not satisfactory to track the stability of these enzymes.

Proactive esophageal cooling during radiofrequency cardiac ablation: data update including applications in very high-power short duration ablation.

Introduction: Proactive esophageal cooling reduces injury during radiofrequency (RF) ablation of the left atrium (LA) for the treatment of atrial fibrillation (AF). New catheters are capable of higher wattage settings up to 90 W (very high-power short duration, vHPSD) for 4s. Varying power and duration however does not eliminate the risk of thermal injury.

Role of amino acid substitutions on proteolytic stability of histatin 5 in the presence of secreted aspartyl proteases and salivary proteases.

Histatin 5 (Hst5) is a 24-amino-acid peptide naturally present in human saliva that has been proposed as a potential antifungal therapeutic. However, Hst5 is susceptible to degradation by secreted aspartyl proteases (Saps) produced by Candida albicans, which could limit its efficacy as a therapeutic. To better understand the role of the lysine residues of Hst5 in proteolysis by C.

PairK: Pairwise k-mer alignment for quantifying protein motif conservation in disordered regions.

Protein-protein interactions are often mediated by a modular peptide recognition domain binding to a short linear motif (SLiM) in the disordered region of another protein. To understand the features of SLiMs that are important for binding and to identify motif instances that are important for biological function, it is useful to examine the evolutionary conservation of motifs across homologous proteins. However, the intrinsically disordered regions (IDRs) in which SLiMs reside evolve rapidly.
