Deleting the mitochondrial respiration negative regulator MCJ enhances the efficacy of CD8 T cell adoptive therapies in pre-clinical studies.

Mitochondrial respiration is essential for the survival and function of T cells used in adoptive cellular therapies. However, strategies that specifically enhance mitochondrial respiration to promote T cell function remain limited. Here, we investigate methylation-controlled J protein (MCJ), an endogenous negative regulator of mitochondrial complex I expressed in CD8 cells, as a target for improving the efficacy of adoptive T cell therapies.

Knowledge, Judgment, and Skills in Reproductive Health Care and Abortion Are Essential to the Practice of Obstetrics and Gynecology.

A social contract exists between medicine and society. In fulfilling the social contract to our patients and society, physicians have an obligation to provide the evidence-based care that patients want and need. What do the data regarding knowledge, judgment, and skills required to practice obstetrics and gynecology show? Obstetrics and gynecology job task analyses assess the importance of knowledge, judgment, and skills through surveys asking practicing physicians about the criticality and frequency of a variety of task statements to create an importance score.

Increased PHOSPHO1 expression mediates cortical bone mineral density in renal osteodystrophy.

Patients with advanced chronic kidney disease (CKD) often present with skeletal abnormalities, a condition known as renal osteodystrophy (ROD). While tissue non-specific alkaline phosphatase (TNAP) and PHOSPHO1 are critical for bone mineralization, their role in the etiology of ROD is unclear. To address this, ROD was induced in both WT and Phospho1 knockout (P1KO) mice through dietary adenine supplementation.

Treatment of COVID-19 Patients with Two Units of Convalescent Plasma in a Resource-Constrained State.

Importance: Many therapies are used to treat COVID-19, the disease caused by the virus SARS-CoV-2, including convalescent plasma. The clinical utility of using 2 units of convalescent plasma for COVID-19 hospitalized patients is not fully understood.

Objective: Many therapies are used to treat COVID-19, the disease caused by the virus SARS-CoV-2, including convalescent plasma.

Animal welfare requirements in publishing guidelines.

Descriptions of measures taken to optimize animal welfare are often absent from scientific reports of animal experiments. One reason may be that journal guidelines inadequately compel authors to provide such information. In this study, online English language versions of the 'Guidelines to authors' (GTAs) from 54 national biomedical journals were examined for neutral (unrelated to welfare) and non-neutral keywords referring to: animal welfare; the '3Rs'; the ARRIVE (2010) guidelines, and regulations pertaining to animal experimentation.

Tenascin-C is a driver of inflammation in the DSS model of colitis.

Inflammatory Bowel Disease (IBD) is a grouping of chronic inflammatory disorders of the gut. Tenascin-C is a pro-inflammatory, extracellular matrix protein found upregulated in IBD patients and whilst a pathological driver of chronic inflammation, its precise role in the etiology of IBD is unknown. To study tenascin-C's role in colitis pathology we investigated its expression in a murine model of IBD.

The Certification Process Driving Patient Safety.

In 2016, the American Board of Medical Specialties (ABMS) and the National Patient Safety Foundation issued a joint call encouraging each ABMS member board to integrate patient safety principles and activities into their initial and continuous certification processes. This article describes how the American Board of Obstetrics and Gynecology integrates various aspects of patient safety principles into its initial and continuous certification processes. The authors first describe how they assess patient safety within their initial certification processes.

Prp22 and spliceosome components regulate chromatin dynamics in germ-line polyploid cells.

During Drosophila oogenesis, the endopolyploid nuclei of germ-line nurse cells undergo a dramatic shift in morphology as oogenesis progresses; the easily-visible chromosomes are initially polytenic during the early stages of oogenesis before they transiently condense into a distinct '5-blob' configuration, with subsequent dispersal into a diffuse state. Mutations in many genes, with diverse cellular functions, can affect the ability of nurse cells to fully decondense their chromatin, resulting in a '5-blob arrest' phenotype that is maintained throughout the later stages of oogenesis. However, the mechanisms and significance of nurse-cell (NC) chromatin dispersal remain poorly understood.
