The macrocyclic antibiotic mangrolide A has been described to exhibit potent activity against a number of clinically important Gram-negative pathogens. Reported is the first enantioselective total synthesis of mangrolide A and derivatives. Salient features of this synthesis include a highly convergent macrocycle preparation, stereoselective synthesis of the disaccharide moiety, and two β-selective glycosylations. The synthesis of mangrolide A and its analogues enabled the re-examination of its activity against bacterial pathogens, and only minimal activity was observed.

Purpose: With life expectancies increasing worldwide, there is a concomitant rise in the incidence of fragility fractures. As such, low-income and lower-middle-income countries (LICs and LMICs) will be faced with increased incidences of hip fractures. The care of these fractures is adversely affected by various factors that include under-resourced healthcare systems and large socioeconomic disparities, which disproportionately affect patient care in these regions relative to high-income countries.

Objective: This study aims to investigate the preventive effect of walnut oil as medicinal food on abnormal lipid metabolism and its influence on liver metabolites and intestinal flora.
Methods: The rat model of abnormal lipid metabolism was established by feeding high-fat diet and administering a high-fat emulsion via gavage. The rats were randomly assigned to one of the five groups: the normal group (ND), the model group (HFD), and three walnut oil intervention groups differing in dosage [low-dose (OL, 2.

Over the past 30 years, obesity prevalence has markedly increased globally, including among children. Although genome-wide association studies (GWAS) have identified over 1,000 genetic loci associated with obesity-related traits in adults, the genetic architecture of childhood obesity is less well-characterized. Moreover, most childhood obesity GWAS have been restricted to severely obese children, in relatively small sample sizes, and in primarily European ancestry populations.

Background: The evidence on the relationship of dietary antioxidant nutrients with the survival of ovarian cancer (OC) remains scarce.
Objective: This study aimed to investigate these associations in a prospective cohort of Chinese patients with OC.
Methods: In this prospective cohort study, patients with epithelial OC completed a food frequency questionnaire at diagnosis and 12 months post-diagnosis, and were followed from 2015 to 2023.
