Background: Current guidelines for the treatment of multidrug-resistant/rifampin-resistant tuberculosis (MDR/RR-TB) are based on clinical trials evaluating fixed duration regimens. However, when a regimen succeeds, it remains unknown whether a shorter duration could yield the same results. Similarly, if a regimen fails, it is unclear whether extending the treatment could improve outcomes.

Elucidating synthetic parameters to produce crystalline solid-state materials with specific properties remains an outstanding obstacle. Oxychalcogenide materials present their own challenges; gaseous reagents are difficult to control and quantify, and reactions cannot be monitored in situ at elevated temperatures. In this paper, we aim to address the lack of fundamental understanding of oxychalcogenides through the synthesis of LaOTe, by two different routes: traditional solid-state and hydrogen gas-assisted methods.

Retention and adherence to daily oral pre-exposure prophylaxis (PrEP) are critical for effective HIV prevention; however, YMSM exhibit lower rates of both compared to other populations. This is important because young men who have sex with men (YMSM) are at higher risk for HIV, and understanding their challenges can help create better support and interventions. This scoping review synthesizes evidence on the facilitators and barriers to HIV PrEP retention and adherence among YMSM, focusing on individuals aged 10 to 29 years.

Surface-enhanced Raman spectroscopy (SERS) is widely recognized as a powerful analytical technique, offering molecular identification by amplifying characteristic vibrational signals, even at the single-molecule level. While SERS has been successfully applied for a wide range of targets including pesticides, dyes, bacteria, and pharmaceuticals, it has struggled with the detection of molecules with inherently low Raman scattering cross-sections. Urea, a key nitrogen-containing biomolecule and the diamide of carbonic acid, is a prime example of such a challenging target.

Introduction: Nonbacterial thrombotic endocarditis (NBTE) is a rare cardiac manifestation in patients with advanced malignancies of the lungs, pancreas, gynecological system, and gastrointestinal tract. It is often confirmed postmortem by histopathological evidence of sterile platelet-fibrin deposits attached to the endocardium, most often on heart valves. To the best of our knowledge, our case is the first to report multiple heart lesions caused by the systemic effect of cholangiocarcinoma.

The interplay between multiple transcription factors precisely regulates eukaryotic transcription. Here, we report that the protein methyltransferases, MLL2/KMT2B and PRMT1, interact directly and act collectively to regulate gene expression. PRMT1 binds to the N-terminal region of MLL2, considered an intrinsically disordered region, and methylates multiple arginine residues within its RGG/RG motifs.

1,4-Dihydronicotinamide derivatives, including 1-methyl-1,4-dihydronicotinamide (MNAH), are derivatives of the active center of nicotinamide coenzyme (NADH) and are therefore potent radical scavengers. MNAH serves as a useful model of NADH that allows for modeling studies to address the activity of this important biomolecule. In this work, MNAH activity was evaluated against typical free radicals using quantum chemical calculations in physiological environments, with a secondary aim of comparing activity against two physiologically relevant radicals of markedly different stability, HO˙, and HOO˙, to establish which of these is a better model for assessing antioxidant capacity in physiological environments.
