No bones about it: (-)-Norzoanthamine, a promising candidate for an anti-osteoporotic drug, was the target of a total synthesis (see scheme). The final bisaminal formation with AcOH/H(2)O gave the DEFG ring, while the cyclization precursor was prepared by installing the remaining bisaminal unit after oxidative cleavage of the cyclopentanol moiety.

Importance: Excess body fat plays a pivotal role in the pathogenesis of heart failure with preserved ejection fraction (HFpEF). HU6 is a novel, controlled metabolic accelerator that enhances mitochondrial uncoupling resulting in increased metabolism and fat-specific weight loss.
Objective: To assess efficacy and safety of HU6 in reducing body weight, improving peak volume of oxygen consumption (VO2) and body composition among patients with obesity-related HFpEF.

Importance: There is a need to identify the best performing risk prediction model for sentinel lymph node biopsy (SLNB) positivity in melanoma.
Objective: To comprehensively review the characteristics and discriminative performance of existing risk prediction models for SLNB positivity in melanoma.
Data Sources: Embase and MEDLINE were searched from inception to May 1, 2024, for English language articles.

Objective: The aim of the study is to provide insight into the real-world use of therapeutic drug monitoring (TDM) for the most common antiseizure medications (ASMs).
Methods: In total, 137 586 samples from the period 2019-2023 were collected from the five main Danish laboratories performing TDM. A previously described algorithm developed to exclude abnormal TDM results from patient data was applied.

The use of natural organic extracts in nanoparticle synthesis can reduce environmental impacts and reagent costs. With that purpose in mind, a novel biosynthesis procedure for the formation of magnetic iron-oxide nanoparticles (IONPs) using extract in an aqueous medium has been systematically carried out. First, the biosynthesis was optimized for various extract concentrations, prepared by decoction and infusion methods, and yielded IONPs with sizes from 4 to 9 nm.

The conversion of carbon dioxide into fuels and fine chemicals is a highly desirable route for mitigating flue gas emissions. However, achieving selectivity toward olefins remains challenging and typically requires high temperatures and pressures. Herein, we address this challenge using 12 nm copper nanoparticles supported on FeOx micro-rods, which promote the selective hydrogenation of CO to light olefins (C-C) under atmospheric pressure.
