Endothelial-specific knockout of the scramblase TMEM16F impairs in vivo clot formation.

Objective: Loss of function of the phospholipid scramblase (PLS) TMEM16F results in Scott Syndrome, a hereditary bleeding disorder generally attributed to intrinsic platelet dysfunction. The role of TMEM16F in endothelial cells, however, is not well understood. We sought to test the hypothesis that endothelial TMEM16F contributes to hemostasis by measuring bleeding time and venous clotting in endothelial-specific knockout (ECKO) mice.

Association between chiropractic spinal manipulation for sciatica and opioid-related adverse events: A retrospective cohort study.

Background: Patients receiving chiropractic spinal manipulation (CSM) for spinal pain are less likely to be prescribed opioids, and some evidence suggests that these patients have a lower risk of any type of adverse drug event. We hypothesize that adults receiving CSM for sciatica will have a reduced risk of opioid-related adverse drug events (ORADEs) over a one-year follow-up compared to matched controls not receiving CSM.

Methods: We searched a United States (US) claims-based data resource (Diamond Network, TriNetX, Inc.

Triethylamine-mediated protonation-deprotonation unlocks dual-drug self assembly to suppress breast cancer progression and metastasis.

Carrier-free nanomedicines exhibited significant potential in elevating drug efficacy and safety for tumor management, yet their self assembly typically relied on chemical modifications of drugs or the incorporation of surfactants, thereby compromising the drug's inherent pharmacological activity. To address this challenge, we proposed a triethylamine (TEA)-mediated protonation-deprotonation strategy that enabled the adjustable-proportion self assembly of dual drugs without chemical modification, achieving nearly 100% drug loading capacity. Molecular dynamic simulations, supported by experiment evidence, elucidated the underlying self-assembly mechanism.

Retinoic acid antagonizes estrogen signaling to maintain adult uterine cell fate.

Classical tissue recombination experiments demonstrate that cell-fate determination along the anterior-posterior axis of the Müllerian duct occurs prior to postnatal day 7 in mice. However, little is known about how these cell types are maintained in adults. In this study, we provide genetic evidence that a balance between antagonistic retinoic acid (RA) and estrogen signaling activity is required to maintain simple columnar cell fate in adult uterine epithelium.

AMH protects the ovary from doxorubicin by regulating cell fate and the response to DNA damage.

Anti-Müllerian hormone (AMH) protects the ovarian reserve from chemotherapy, and this effect is most pronounced with Doxorubicin (DOX). However, DOX toxicity and AMH rescue mechanisms in the ovary have remained unclear. Herein, we characterize the consequences of these treatments in ovarian cell types using scRNAseq.

Comparison of two strategies of glucocorticoid withdrawal in patients with rheumatoid arthritis in low disease activity (STAR): a randomised, placebo- controlled, double-blind trial.

Objectives: To compare two strategies-a hydrocortisone replacement strategy and a prednisone tapering strategy-for their success in glucocorticoid discontinuation in patients with rheumatoid arthritis (RA) with low disease activity (LDA).

Methods: The Strategies for glucocorticoid TApering in Rheumatoid arthritis (STAR) study was a double- blind, double-placebo randomised controlled trial including patients with RA receiving a stable dose of glucocorticoid 5 mg/day for ≥3 months and were in LDA for ≥3 months. Patients were randomly assigned in a 1:1 ratio to either replace prednisone with 20 mg/day of hydrocortisone for 3 months, then reduce to 10 mg/day for 3 months before discontinuation or to taper prednisone by 1 mg/day every month until complete discontinuation, contingent on maintaining LDA.

Lobaric acid suppresses the stemness potential of colorectal cancer cells through mTOR/AKT.

Stereocaulon alpinum has been found to have potential pharmaceutical properties due to the presence of secondary metabolites such as usnic acid, atranorin, and lobaric acid (LA) which have anticancer activity. On the other hand, the effect of LA on the stemness potential of colorectal cancer (CRC) cells remains unexplored, and has not yet been thoroughly investigated. In this study, we examined the inhibitory activity of LA from Stereocaulon alpinum against the stemness potential of CRC cells and investigated the possible underlying mechanisms.
