Background And Purpose: The transition from a baccalaureate program to a medical curriculum can be a difficult period for some students. Our study asked whether providing students with review materials and a means of assessing their degree of preparedness prior to matriculation influenced actual and perceived performance in 1st-year basic science courses.
Methods: Didactic review materials in basic science subjects encountered in the 1st year were made available to prematriculants online. Access to materials for each subject was contingent upon completion of a pretest. Prematriculants were free to use the materials as they saw fit. Once students matriculated, performance in basic science subjects was compared between those who had accessed the materials and those who had not. Students who accessed the materials were also surveyed to determine if they perceived any benefit from their use.
Results: More than half of matriculants chose to access the intervention materials. There was no significant difference in MCAT, prerequisite grade point average, or total grade point average between those students who chose to access the intervention materials and those who did not. Students who accessed the intervention materials reported gains in confidence in their ability to perform well in medical school. Those students who accessed the intervention materials had significantly higher examination scores in an early basic science course than those who did not.
Conclusions: An online prematriculation intervention can provide useful background material to interested students. Access to this material increased performance in a 1st-year basic science course and was perceived as valuable by students.

A well-constructed pollen wall is essential for pollen fertility, which relies on the contribution of tapetum. Our results demonstrate an essential role of the tapetum-expressed protein phosphatase 2A (PP2A) B'α and B'β in pollen wall formation. The b'aβ double mutant pollen grains harbored sticky remnants and tectum breakages, resulting in failed release.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the result of an exaggerated inflammatory response triggered by a variety of pulmonary and systemic insults. The lung tissues are comprised of a variety of cell types, including alveolar epithelial cells, pulmonary vascular endothelial cells, macrophages, neutrophils, and others. There is mounting evidence that these diverse cell populations within the lung interact to regulate lung inflammation in response to both direct and indirect stimuli.

Background: Amiodarone is an effective anti-arrhythmic drug; however, it is frequently associated with thyroid dysfunction. The aim of this study was to investigate the incidence and risk factor of amiodarone-induced dysfunction in an iodine-sufficient area.
Methods: This retrospective cohort study included 27,023 consecutive patients treated with amiodarone for arrhythmia, using the Korean National Health Insurance database.
Background: To investigate the effectiveness of different bariatric metabolic surgeries in improving metabolic syndrome indicators in patients.
Methods: A retrospective analysis was conducted on obese patients who underwent laparoscopic sleeve gastrectomy (LSG), laparoscopic sleeve gastrectomy + jejunojejunal bypass (LSG + JJB), and laparoscopic Roux-en-Y gastric bypass (LRYGB). Patients were categorized into groups based on their surgical procedure: LSG (N = 199), LSG + JJB (N = 242), and LRYGB (N = 288).
