Cost-effectiveness Analysis of Uterus Transplantation versus Gestational Carrier for Treatment of Absolute Uterine Factor Infertility.

Importance: Patients with uterine factor infertility (UFI) have few options for family building. Uterus transplant is a feasible treatment for some patients; however, cost remains a significant concern.

Objective: To compare the cost effectiveness of treatment for patients with absolute uterine factor infertility to achieve 1-2 singleton births by gestational carrier or uterus transplant DESIGN: Decision analysis from the United States healthcare sector perspective, with time horizons to achieve one or two singleton births.

Arrhythmogenic calmodulin variants D131E and Q135P disrupt interaction with the L-type voltage-gated Ca channel (Ca1.2) and reduce Ca-dependent inactivation.

Aim: Long QT syndrome (LQTS) and catecholaminergic polymorphism ventricular tachycardia (CPVT) are inherited cardiac disorders often caused by mutations in ion channels. These arrhythmia syndromes have recently been associated with calmodulin (CaM) variants. Here, we investigate the impact of the arrhythmogenic variants D131E and Q135P on CaM's structure-function relationship.

Unveiling the promise of peptide nucleic acids as functional linkers for an RNA imaging platform.

Linkers in chemical biology provide more than just connectivity between molecules; their intrinsic properties can be harnessed to enhance the stability and functionality of chemical probes. In this study, we explored the incorporation of a peptide nucleic acid (PNA)-based linker into RNA-targeting probes to improve their affinity and specificity. By integrating a PNA linker into a small molecule probe of the Riboglow platform, we enabled dual binding events: cobalamin (Cbl)-RNA structure-based recognition and sequence-specific PNA-RNA interaction.

Image-guided percutaneous mesenteric biopsy: diagnostic yield and safety profile.

Purpose: To evaluate the diagnostic yield and safety profile of percutaneous image-guided biopsy of mesenteric lesions.

Materials, Methods, And Procedures: Image-guided percutaneous biopsies of the mesentery at a single institution from 2000 to 2022 were identified and reviewed. Relevant demographic and procedural data were abstracted from the medical record.

Photocatalytic Partial Water Oxidation Promoted by a Hydrogen Acceptor-Hydroxyl Mediator Couple.

Hydrogen peroxide (HO) is an important chemical in synthetic chemistry with huge demands. Photocatalytic synthesis of HO via oxygen reduction and water oxidation reactions (ORR and WOR) is considered as a promising and desirable solution for on-site applications. However, the efficiency of such a process is low due to the poor solubility of molecular oxygen and the rapid reverse reaction of hydroxyl radicals (OH) with hydrogen atoms (H).
