Lung endothelium resides at the interface between the circulation and the underlying tissue, where it senses biochemical and mechanical properties of both the blood as it flows through the vascular circuit and the vessel wall. The endothelium performs the bidirectional signaling between the blood and tissue compartments that is necessary to maintain homeostasis while physically separating both, facilitating a tightly regulated exchange of water, solutes, cells, and signals. Disruption in endothelial function contributes to vascular disease, which can manifest in discrete vascular locations along the artery-to-capillary-to-vein axis.

Understanding the composition, phenotype, and spatial organization of T cells and other microenvironmental populations in the pediatric AML bone marrow (BM) is essential for informing future immunotherapeutic trials about targetable immune-evasion mechanisms specific to pediatric AML. Here, we conducted a multidimensional analysis of the tumor immune microenvironment in pediatric AML and non-leukemic controls.

There is a vital need for effective therapeutics to prevent and/or treat severe RSV infection in these high-risk individuals. The development and pre-clinical testing of candidate RSV therapeutics could be accelerated by their evaluation in animals models that recapitulate bronchiolitis and bronchopneumonia; both hallmark features of severe RSV infection of humans.

Methods: We reviewed data of patients with primary liver tumors treated with Y-90 prescription doses of at least 150 Gy.
The 22-hydroxy-23,24-bisnorchol-4-ene-3-one (4-HBC) is a C22 steroid synthon of pharmaceutical interest that can be produced as a lateral end-product of the catabolism of natural sterols (e.g., cholesterol or phytosterols).

Prior studies investigating seizure control from posterior quadrant epilepsy surgery are limited. In this study, a retrospective database of patients undergoing surgery for left sided posterior cortex epilepsy at a single large level 4 epilepsy center was analyzed between August 2008 to April 2021 in order to characterize seizure control outcomes.

Aim: This scientific statement aims to evaluate 5 important aspects of psychosocial health (depression, stress, anxiety, fatigue, and quality of life) after a stroke to provide a framework for related nursing care across the poststroke continuum.
Paracoccidioidomycosis (PCM) is an endemic fungal disease that occurs in Latin America and primarily affects humans. The disease has been rarely documented in non-human primates. This report details a disseminated and fatal case of PCM caused by Paracoccidioides brasiliensis in a western black-handed tamarin (Saguinus niger) under human care.

This study aimed to assess the impact of sex on sociodemographic, clinical, and laboratory parameters in patients with HF who were included in the Colombian Heart Failure Registry (RECOLFACA).
Methods: This was a cross-sectional analytical research.
Our study was to characterize sarcopenia in C57BL/6J mice using a clinically relevant definition to investigate the underlying molecular mechanisms. Aged male (23-32 months old) and female (27-28 months old) C57BL/6J mice were classified as non-, probable-, or sarcopenic based on assessments of grip strength, muscle mass, and treadmill running time, using 2 SDs below the mean of their young counterparts as cutoff points. A 9%-22% prevalence of sarcopenia was identified in 23-26 month-old male mice, with more severe age-related declines in muscle function than mass.

Because these groups are overrepresented among the farm workforce, exploring SNAP utilization among farm communities may clarify the role it plays in alleviating food insecurity.
Methods: In-depth interviews were conducted with 31 farmworkers and farm owners.
Some Basidiomycete fungi are important plant pathogens, and certain species have been associated with the grapevine trunk disease esca. We present the genomes of 4 species associated with esca: Fomitiporia mediterranea, Fomitiporia polymorpha, Tropicoporus texanus, and Inonotus vitis. We generated high-quality phased genome assemblies using long-read sequencing.

In an model system of HIV latency, it was reported that early exposure to class I histone deacetylase (HDAC) inhibitors might prevent these more recently infected cells from entering a state of stable viral latency. This finding raises the possibility that co-administration of HDAC inhibitors at the time of ART initiation may prevent the establishment of much of the HIV reservoir.

Developmental screening is vital to early detection of developmental delay and autism spectrum disorder, and early intervention (EI) referral. This study sought to examine whether implementation of a standardized clinical workflow using electronic screening tools improved both rates of developmental screening, and the number of children identified at risk for developmental delay, in a federally qualified health center (FQHC).

Assessing the allostatic load of workers in the context of COVID -19 is of vital importance to elucidate the physiological responses to social and work stress. This is an integrative review of the literature including seven established steps: 1) identification of the topic and the guiding question; 2) definition of MeSH terms and search equations; 3) search in databases following defined criteria; 4) data collection according to inclusion criteria; 5) evaluation of the studies included in the integrative review; 6) discussion of results; and 7) presentation of the review/synthesis of knowledge. Seventeen studies were included, of which 15 were cross-sectional observational studies and two were longitudinal studies.
