Marketed endothelin receptor antagonists (ERAs) have been associated with testicular tubular atrophy and decreases in male animal fertility in chronic toxicity studies in rats and dogs. Consistent with these findings, reduced sperm count has been observed in the clinical setting and is considered a potential class risk with chronic administration of ERAs. In contrast, no such effects on male animal fertility are noted with angiotensin II type 1 receptor blocker (ARB) treatment.

Carbon fiber reinforced polymers (CFRPs, or composites) are increasingly replacing traditional manufacturing materials used in the automobile, aerospace, and energy sectors. With this shift, it is vital to develop end-of-life processes for CFRPs that retain the value of both the carbon fibers and the polymer matrix. Here we demonstrate a strategy to upcycle pre- and postconsumer polystyrene-containing CFRPs, cross-linked with unsaturated polyesters or vinyl esters, to benzoic acid.

The effect of acute exercise on circulating concentrations of vitamin D metabolites is unclear. To address this knowledge gap, we examined the effect of a bout of treadmill-based exercise versus rest on circulating concentrations of 25(OH)D, 25(OH)D, 3-epi-25(OH)D, 24,25(OH)D, 1,25(OH)D, and vitamin D and D in healthy men and women. Thirty-three healthy adults (14 females, 41 (15) years, body mass index 26.

Fungal secondary metabolite (SM) biosynthetic gene clusters (BGCs) containing dimethylallyltryptophan synthases (DMATSs) produce structurally diverse prenylated indole alkaloids with wide-ranging activities that have vast potential as human therapeutics. To discover new natural products produced by DMATSs, we mined the Department of Energy Joint Genome Institute's MycoCosm database for DMATS-containing BGCs. We found a DMATS BGC in CBS 101889, which also contains a nonribosomal peptide synthetase (NRPS).

Article Synopsis
  • IgA nephropathy (IgAN) involves kidney damage caused by immune complexes formed from a specific type of IgA that has unusual glycan structures, leading to complications like kidney failure in many patients.
  • To study this condition, researchers created a model using engineered immune complexes in mice to mimic IgAN and examined the effects of sparsentan, a drug that targets certain receptors in the body.
  • The results showed that sparsentan reduced kidney cell overgrowth and inflammation, suggesting it could help protect against kidney damage from IgAN, indicating potential for human treatment insights.

Article Synopsis
  • The study investigates how sparsentan, a dual endothelin and angiotensin receptor antagonist, can reduce kidney injury in a mouse model of immunoglobulin A nephropathy (IgAN).
  • Treatment with sparsentan showed a faster and greater decrease in the albumin:creatine ratio compared to losartan, a selective angiotensin II receptor blocker, indicating its superior efficacy.
  • The findings offer insights into the mechanisms of sparsentan's benefits in protecting kidneys from IgAN compared to using AT1R antagonism alone, supporting its recent approval for clinical use in high-risk patients.

Article Synopsis
  • This study focuses on skeletal muscle, which plays a significant role in metabolic conditions like type 2 diabetes, and aims to better understand the genetic factors behind these traits by utilizing advanced genetic mapping techniques.
  • Researchers analyzed 287 human skeletal muscle biopsies to identify various cell types and regulatory elements through single nucleus sequencing, pinpointing thousands of genetic variants, including expression and chromatin accessibility QTLs.
  • The findings revealed the importance of chromatin profiling in discovering regulatory mechanisms, indicating that specific genetic signals associated with type 2 diabetes are linked to chromatin accessibility in muscle fibers, enhancing our understanding of muscle biology and its relation to metabolic diseases.

Aim: To develop and explore the validity of a Patient Reported Experience Measure (PREM) for adult inpatient diabetes care.

Method: 27 in-depth interviews were conducted to inform the development of the 42-item PREM which was cognitively tested with 10 people. A refined 38-item PREM was piloted with 228 respondents completing a paper (n = 198) or online (n = 30) version.

Unlabelled: Secondary metabolites (SMs) are biologically active small molecules, many of which are medically valuable. Fungal genomes contain vast numbers of SM biosynthetic gene clusters (BGCs) with unknown products, suggesting that huge numbers of valuable SMs remain to be discovered. It is challenging, however, to identify SM BGCs, among the millions present in fungi, that produce useful compounds.

Background: The Endometriosis Health Profiles (EHPs), the EHP-30 and EHP-5, are patient-reported outcome measures that were developed to measure the health-related quality of life (HRQoL) of women living with endometriosis. Prior to their development, a systematic review was undertaken which identified that the HRQoL of women living with endometriosis was poorly understood, with only three medical and one surgical study identified.

Objective And Rationale: The 20-year anniversary of the EHP-30 provided a timely opportunity to assess how the tools have been used and explore what the findings tell us about the impact of endometriosis and its associated treatments upon women's QoL.

Background: NASH causes a tremendous health care burden in the United States. A glucagon-like peptide-1 agonist, semaglutide (Sema), treatment resulted in hepatic steatosis reduction in clinical trials of NASH. Lysophosphatidic acid receptor 1 antagonists are known to have antifibrotic effects in several organs.

is a serious human pathogen causing life-threatening Aspergillosis in immunocompromised patients. Secondary metabolites (SMs) play an important role in pathogenesis, but the products of many SM biosynthetic gene clusters (BGCs) remain unknown. In this study, we have developed a heterologous expression platform in , using a newly created genetic dereplication strain, to express a previously unknown BGC from and determine its products.

  • Alport syndrome (AS) is a genetic disorder that causes kidney disease and potentially hearing loss, typically treated with renin-angiotensin system inhibitors, but newer treatments are needed.
  • Sparsentan, a dual receptor antagonist, demonstrated effectiveness in a mouse model for AS by reducing kidney and hearing-related issues, showing improvements in kidney function and lifespan compared to traditional treatments like losartan.
  • The study suggests that sparsentan could be a promising therapy for patients with Alport syndrome, addressing both kidney damage and hearing loss, even when treatment starts after kidney issues have developed.

Background: Cerebrotendinous xanthomatosis (CTX) is a rare recessive genetic disease characterized by disruption of bile acid synthesis due to inactivation of the CYP27A1 gene. Treatment is available in the form of bile acid replacement. CTX is likely underdiagnosed, and prevalence estimates based on case diagnosis are probably inaccurate.

Background: Fatigue and breathlessness are the two most common and distressing symptoms for patients with chronic heart failure. They affect a patient's quality of life and ability to undertake activities of daily living. Currently there are no symptom specific measures for fatigue and breathlessness available or developed and validated for use with this patient group and no questionnaire that incorporates both symptoms into one measure.

Aims: The aim of this study was to develop and evaluate machine-learning-based computerized adaptive tests (CATs) for the Oxford Hip Score (OHS), Oxford Knee Score (OKS), Oxford Shoulder Score (OSS), and the Oxford Elbow Score (OES) and its subscales.

Methods: We developed CAT algorithms for the OHS, OKS, OSS, overall OES, and each of the OES subscales, using responses to the full-length questionnaires and a machine-learning technique called regression tree learning. The algorithms were evaluated through a series of simulation studies, in which they aimed to predict respondents' full-length questionnaire scores from only a selection of their item responses.

Acalculia, an acquired disability following a brain injury, involves difficulty processing numerical information and/or calculations. Acalculia is not routinely screened for, and as a result there is a lack of understanding about the nature and prevalence and the impact of the condition. This qualitative study was initiated by stroke survivors with a strong interest in acalculia.
