Nuclear Magnetic Resonance (NMR)-Based Lipidomics Reveal the Association of Altered Red Blood Cell (RBC) Membrane Lipidome with the Presence and the Severity of Coronary Artery Stenosis.

Coronary heart disease (CHD) is the leading cause of morbidity and mortality worldwide despite significant improvements in diagnostic modalities. Emerging evidence suggests that erythrocytes, or red blood cells (RBCs), are one of the most important contributors to the events implicated in atherosclerosis, although the molecular mechanisms behind it are under investigation. We used NMR-based lipidomic technology to investigate the RBC lipidome in patients with CHD compared to those with normal coronary arteries (NCAs), all angiographically documented, and its correlation with coronary artery stenosis.

A phase I, randomized, placebo-controlled trial to evaluate the pharmacokinetics, safety, and tolerability of nirsevimab in healthy Chinese adults.

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infection (LRTI) in infants worldwide. Nirsevimab, an extended half-life monoclonal antibody against RSV, is approved in China for the prevention of RSV lower respiratory tract disease in infants; however, global nirsevimab trials did not enroll Chinese infants. To inform the investigation of nirsevimab for the prevention of RSV LRTI in Chinese infants, this Phase I, randomized, placebo-controlled trial evaluated the pharmacokinetics (PK) and safety of nirsevimab in healthy Chinese adults.

Evaluation of infectious complications in patients with myelodysplastic syndromes: a prospective cohort study from the Canadian MDS registry.

Infections are a significant cause of morbidity and mortality in myelodysplastic syndrome (MDS). Precise estimates of infection frequency and severity with modern therapies are uncertain. We conducted a retrospective analysis of a prospective cohort enrolled in a Canadian MDS registry and characterized the frequency and severity of infectious complications.

A [Mn] Defective Supertetrahedron T3 and Its Dimeric [Mn] Analogue.

The initial use of 2-(pyridin-2-yl)propane-1,3-diol (pypdH) in Mn cluster chemistry has afforded two new mixed-valence polynuclear Mn clusters, namely, [MnΟ(pypd)(hmp)(OCCMe)] () and [MnΟ(N)(pypd){(py)CO}(OCEt)] () (hmp = deprotonated 2-hydroxymethylpyridine; (py)CO = deprotonated gem-diol form of di-2-pyridyl ketone). Compound features a novel [Mn Mn(μ-O)(μ-O)(μ-OR)] structural core resembling a supertetrahedron T3, lacking two apexes, while complex has a [Mn Mn (μ-O)(μ-O)(μ-N)(μ-OR)(μ-OR)] core consisting of two [Mn] subunits related to and thus is a dimeric analogue of . Direct current (dc) magnetic susceptibility studies revealed the presence of dominant antiferromagentic exchange interactions between the Mn ions in complexes and and small ground state spin values for both compounds.
