To successfully mount infections, nearly all bacterial pathogens must acquire iron, a key metal cofactor that primarily resides within human hemoglobin. causes the life-threatening respiratory disease diphtheria and captures hemoglobin for iron scavenging using the surface-displayed receptor HbpA. Here, we show using X-ray crystallography, NMR, and in situ binding measurements that selectively captures iron-loaded hemoglobin by partially ensconcing the heme molecules of its α subunits.

There is a limited understanding of the pathways that lead to victim-perpetrator overlap in adolescent dating violence (ADV) particularly in developing countries such as China. Applying a latent class approach, the present study focuses on whether the overlap can be explained by theoretical constructs grounded in social learning, general strain, and social bonding theories, and whether these constructs relate to underexplored mediating mechanisms or are direct precursors. The study sample consisted of 1,787 dating adolescents (39.

Objective: To compare the prevalence and clinical characteristics of early gestational diabetes (eGDM) and associated birth outcomes amongst women of different ethnic groups.

Research Design And Methods: This is a secondary analysis of an international, multicentre randomized controlled trial of treating eGDM among pregnant women with GDM risk factors enrolled <20 weeks' gestation. The diagnosis of GDM was made using WHO-2013 criteria.

Objective: To investigate the association of timing of commencing glucose management with glycemia, glycemic variability, and pregnancy outcomes among women with early gestational diabetes mellitus (GDM).

Research Design And Methods: In this substudy among participants of a trial of immediate vs delayed treatment of early GDM diagnosed by 2013 World Health Organization criteria, all women treated immediately and those with delayed diagnosis at 24-28 weeks' gestation (treated as if late GDM) were instructed to monitor capillary blood glucose (BG) four times a day (fasting and 2-h postprandial) until delivery. Optimal glycemia was defined as ≥95% of BG measurements between 70 and 140 mg/dL (3.

Aim: To evaluate the incidence and predictors of postpartum dysglycaemia among high-risk women who develop early gestational diabetes (eGDM) prior to 20 weeks' gestation.

Methods: This is a sub-study of the Treatment of Booking Gestational Diabetes (TOBOGM) Study, a randomised controlled trial of early or deferred treatment for women with risk factors for gestational diabetes diagnosed with eGDM, using current WHO criteria. Overt diabetes in pregnancy was excluded.
