Cxcl10 is required for survival during SARS-CoV-2 infection in mice.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of the coronavirus disease 2019 (COVID-19) pandemic, remains endemic worldwide ∼5 years since the first documented case. Severe COVID-19 is widely considered to be caused by a dysregulated immune response to SARS-CoV-2 within the respiratory tract. Circulating levels of the chemokine CXCL10 are strongly positively associated with poor outcome; however, its precise role in pathogenesis and its suitability as a therapeutic target have remained undefined.

Financial Barriers to Rural Graduate Medical Education: Medicare Funding Methods for Sole Community and Medicare-Dependent Hospitals.

Purpose: Policymakers are exploring options to address rural-urban physician maldistribution, including reducing rural residency training barriers. This study estimated Medicare graduate medical education (GME) reimbursement that sole community hospitals (SCHs) and Medicare-dependent hospitals (MDHs) are disqualified from receiving compared with hospitals under the Prospective Payment System (PPS) and calculated the GME reimbursement per resident for MDHs and SCHs under different scenarios.

Method: This simulation study used Healthcare Cost Report Information System data on hospitals that had been SCHs or MDHs between 2011 and 2021 and did not have any resident full-time equivalents (FTEs) in the most recent year.

Cxcl10 is protective during mouse-adapted SARS-CoV-2 infection.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of the coronavirus disease 2019 (COVID-19) pandemic, remains endemic worldwide. Circulating levels of the chemokine CXCL10 are strongly positively associated with poor outcome; however, its precise role in SARS-CoV-2 pathogenesis and its suitability as a therapeutic target have remained undefined. Here, we challenged mice genetically deficient in Cxcl10 with a mouse-adapted strain of SARS-CoV-2.

Utilizing both IgA tissue transglutaminase and IgG-deamidated gliadin peptide antibodies offers accurate celiac disease diagnosis without duodenal biopsy.

Background: Gastroenterologists still raise concerns about adopting a non-biopsy strategy for diagnosing celiac disease (CeD) in adults.

Aim: To assess the performance of the concurrent detection of two autoantibodies targeting two independent antigens, tissue transglutaminase (tTG) and deamidated gliadin peptides (DGP).

Methods: This prospective, multicenter, binational study collected consecutive patients with a high pre-test probability for CeD.

Assessing the breadth and multidisciplinarity of the conservation curriculum in the United Kingdom and Australia.

There have been repeated calls to train conservationists capable of transcending disciplinary boundaries. However, little empirical work has been done to document conservation teaching. We investigate the content taught in conservation higher education across the United Kingdom and Australia.

Risk factors for hyphema following goniotomy or trabecular bypass stent placement combined with phacoemulsification.

Purpose: To report the rates and risk factors for layered hyphemas after goniotomy (PG) and trabecular bypass stent (PTBS) surgery combined with phacoemulsification.

Methods: Patient data was obtained using a retrospective chart review from adult patients (18 years of age or older) undergoing either PG or PTBS at the West Virginia University Eye Institute between 2013 and 2023. Generalized estimating equations were used to identify significant predictors of layered hyphema on post-operative day one.

An updated model of rural hospital financial distress.

Purpose: To create a model that predicts future financial distress among rural hospitals.

Methods: The sample included 14,116 yearly observations of 2311 rural hospitals recorded between 2013 and 2019. We randomly separated all sampled hospitals into a training set and test set at the start of our analysis.

Regulatory elements in (7q21.3) locus contribute to genetic control of coronal nonsyndromic craniosynostosis and bone density-related traits.

Purpose: The etiopathogenesis of coronal nonsyndromic craniosynostosis (cNCS), a congenital condition defined by premature fusion of 1 or both coronal sutures, remains largely unknown.

Methods: We conducted the largest genome-wide association study of cNCS followed by replication, fine mapping, and functional validation of the most significant region using zebrafish animal model.

Results: Genome-wide association study identified 6 independent genome-wide-significant risk alleles, 4 on chromosome 7q21.

Taxonomic revision of fleshy species of , and (Thelephorales) from Australasia.

Stipitate Thelephorales are basidiomycetous, mostly hydnoid, ectomycorrhizal fungi. Some species have declined considerably, and some are threat-listed as vulnerable or endangered. These ecological concerns require a well-resolved taxonomy to understand diversity in this group of fungi and facilitate conservation.

Ghrelin Modulates Voltage-Gated Ca Channels through Voltage-Dependent and Voltage-Independent Pathways in Rat Gastric Vagal Afferent Neurons.

The orexigenic gut peptide ghrelin is an endogenous ligand for the growth hormone secretagogue receptor type 1a (GHSR1a). Systemic ghrelin administration has previously been shown to increase gastric motility and emptying. While these effects are known to be mediated by the vagus nerve, the cellular mechanism underlying these effects remains unclear.

LRRK2 kinase activity is necessary for development and regeneration in Nematostella vectensis.

Background: The starlet sea anemone, Nematostella vectensis, is an emerging model organism with a high regenerative capacity, which was recently found to possess an orthologue to the human Leucine Rich Repeat Kinase 2 (LRRK2) gene. Mutations in this gene are the most common cause of inherited Parkinson's Disease (PD), highlighting the importance of understanding its function. Despite two decades of research, however, the function of LRRK2 is not well established.

Regional Heterogeneity in Intestinal Epithelial Barrier Permeability and Mesenteric Perfusion After Thoracic Spinal Cord Injury.

Background: Spinal cord injury (SCI) disrupts intestinal barrier function, thereby increasing antigen permeation and leading to poor outcomes. Despite the intestinal tract's anatomic and physiologic heterogeneity, studies following SCI have not comprehensively addressed intestinal pathophysiology with regional specificity.

Aims And Methods: We used an experimental model of high thoracic SCI to investigate (1) regional mucosal oxidative stress using dihydroethidium labeling; (2) regional paracellular permeability to small- and large-molecular probes via Ussing chamber; (3) regional intestinal tight junction (TJ) protein expression; and (4) hindgut perfusion via the caudal mesenteric artery.

Rural Hospital Closures: A Scoping Review of Studies Published Between 1990 and 2020.

Between 1990 and 2020, 334 rural hospitals closed in the United States, and since 2011 hospital closures have outnumbered new hospital openings. This scoping review evaluates peer-reviewed studies published since 1990 with a focus on rural hospital closures, synthesizing studies across six themes: 1) health care policy environment, 2) precursors to rural hospital closures, 3) economic impacts, 4) effects of rural hospital closures on access to care, 5) health and community impacts, and 6) definitions of rural hospitals and communities. In the 1990s, rural hospitals that closed were smaller, while rural hospitals that closed in the 2010s tended to have more beds.

Sex differences in cholinergic signaling affect functional outcomes for theta-gamma coordination in hippocampal subcircuits following experimental febrile status epilepticus.

Objective: Sex determines cognitive outcome in animal models of early life seizure, where males exhibit impaired hippocampal-dependent learning and memory compared with females. The physiological underpinnings of this sex effect are unclear. Cholinergic signaling is essential for the generation of hippocampal oscillations, and supplementation of cholinergic precursors prior to status epilepticus in immature male rats prevents subsequent memory deficits.

Apical expansion of calvarial osteoblasts and suture patency is dependent on fibronectin cues.

The skull roof, or calvaria, is comprised of interlocking plates of bones that encase the brain. Separating these bones are fibrous sutures that permit growth. Currently, we do not understand the instructions for directional growth of the calvaria, a process which is error-prone and can lead to skeletal deficiencies or premature suture fusion (craniosynostosis, CS).

() . in Australia: Neither a nor a .

is described as a new porphyrellus-like genus of to accommodate , a dark brown to dull lilac/violet, or rarely, nearly black bolete with a series of oxidation reactions progressing from blue to red then nearly black and a dark brown spore deposit. Idiosyncratic blue-green pigment encrustations (cyanogranules) and a similarly colored reaction of the hyphae located on pileus and stipe surfaces are also diagnostic. Phylogenetic analyses of nuclear large-subunit rDNA (nrLSU), translation elongation factor 1-alpha (), and the second largest subunit of RNA polymerase II () infer as a unique generic lineage with two species, one of which is newly described (.

Differences in Sleep EEG Coherence and Spindle Metrics in Toddlers With and Without Language Delay: A Prospective Observational Study.

Background: Sleep plays a crucial role in early language development, and sleep disturbances are common in children with neurodevelopmental disorders. Examining sleep microarchitecture in toddlers with and without language delays can offer key insights into neurophysiological abnormalities associated with atypical neurodevelopmental trajectories and potentially aid in early detection and intervention.

Methods: Here, we investigated electroencephalogram (EEG) coherence and sleep spindles in 16 toddlers with language delay (LD) compared with a group of 39 typically developing (TD) toddlers.
