Are medical school preclinical tests biased for sex and race? A differential item functioning analysis.
BMC Med Educ

University of Minnesota Medical School, 420 Delaware Street SE, Mayo Building, Minneapolis, MN, 55455, USA.
Background: A common practice in assessment development, fundamental for fairness and consequently the validity of test score interpretations and uses, is to ascertain whether test items function equally across test-taker groups. Accordingly, we conducted differential item functioning (DIF) analysis, a psychometric procedure for detecting potential item bias, for three preclinical medical school foundational courses based on students' sex and race.
Methods: The sample included 520, 519, and 344 medical students for anatomy, histology, and physiology, respectively, collected from 2018 to 2020.

Traffic signals, while reducing conflicts within intersections, often lead to stop-and-go behaviors in approaching vehicles, negatively impacting traffic flow in terms of safety, efficiency, and fuel consumption. Aimed at minimizing the traffic oscillations caused by traffic signals through Connected and Autonomous Vehicles (CAVs) and meeting real-time operational needs, this paper proposes a Risk-Based Adaptive Cruise Control (RACC). RACC designs the constraints of approaching a signalized intersection as expected risks, enabling compliance with all constraints while being adaptable to basic road scenarios.

National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, 618# Fengqi East Road, Hangzhou, 310000, Zhejiang, China.
Purpose: To calculate the crystalline lens power and astigmatism, as well as their changes following cycloplegia, in individuals with myopia using swept-source optical coherence tomography (SS-OCT).
Methods: Participants were divided into two groups according to axial length (AL). Crystalline lens parameters, including power, lens thickness (LT), anterior chamber depth (ACD), and astigmatism, were measured with SS-OCT and analysed before and after cycloplegia.
Ginkgolide B regulates apoptosis, oxidative stress, and mitochondrial dysfunction in MPP-induced SK-N-SH cells by targeting HDAC4/JNK pathway.

Ginkgolide B (GB) is a bioactive constituent found in Ginkgo biloba leaves that has been long recognized as a protective agent against many neurological disorders. Our study aimed to examine the effect of GB in an in vitro Parkinson's disease (PD) model and to investigate its neuroprotective mechanism as a primary objective. SK-N-SH cells were challenged with 1-methyl-4-phenylpyridinium (MPP) to act as a PD-like model of neuronal damage.

Objectives: Soybeans have various positive effects on health, including anti-inflammatory and preventing kidney damage. There is concern regarding the phytoestrogen content due to the high isoflavone content in soybeans. Various forms of soybean processing have been tried; in this study, the hydrolysis method will be used to obtain the active substance Arginine-Glycine-Aspartate (RGD) tripeptide in soybean protein hydrolyzed by bromelain (SPHB).
