Iodine Deficiency Exacerbates Thyroidal and Neurological Effects of Developmental Perchlorate Exposure in the Neonatal and Adult Rat.

Thyroid hormones (THs) require iodine for biosynthesis and play critical roles in brain development. Perchlorate is an environmental contaminant that reduces serum THs by blocking the uptake of iodine from the blood to the thyroid gland. Using a pregnant rodent model, we examined the impact of maternal exposure to perchlorate under conditions of dietary iodine deficiency (ID) on the brain and behavior of offspring.

Education Research: Utilization of Simulation in Residency Programs: A Survey of Adult Neurology Residency Program Directors.

Background And Objectives: Previous research has demonstrated that simulation-based medical education (SBME) can improve neurology trainees' confidence, knowledge, and competence. However, a general needs assessment and review of current SBME used within neurology are needed to guide SBME curriculum development. The objective of this study was to describe the current use of SBME in resident education and to assess perceived barriers to expanding SBME interventions.

Connections After Cancer: Adolescent and Young Adult Survivors' Perspectives on Forming New Friendships After Cancer.

Objective: The psychological and social challenges of an adolescent and young adult (AYA) cancer diagnosis often transcend physical health, impacting one's social network during a time when peer connections may be most crucial for support. The current study examines adolescent and young adult (AYA) cancer survivors' perspectives on how cancer impacts their thoughts and behaviors toward forming new peer relationships.

Methods: Thirty-five YA survivors (Mean age = 33 ± 5.

Molecular basis of hemoglobin binding and heme removal in .

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.

Sexual Boredom Inventory (SBI): Development and Initial Validation.

This study presents the development and validation of the Sexual Boredom Inventory (SBI), a 6-item measure assessing sexual boredom as a temporary, context-dependent state. Initial items were drafted from data obtained through qualitative analysis, and the SBI was tested using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) with a sample of adults reporting on their sexual experiences in the past month. A single-factor model was found to be the best fit, with four items dropped during refinement.
