Occurrence, Bioaccumulation, and Human Exposure Risk of the Antiandrogenic Fluorescent Dye 7-(Dimethylamino)-4-methylcoumarin and 7-(Diethylamino)-4-methylcoumarin in the Dongjiang River Basin, South China.

Recently, 7-diethylamino-4-methylcoumarin (DEAMC) has been identified as a potent antiandrogenic compound in the surface water; however, little is known about the antiandrogenic potentials of other synthetic coumarins and their occurrence in the aquatic ecosystem. In this study, for the first time, we observed that 7-dimethylamino-4-methylcoumarin (DAMC) elicited androgen receptor (AR) antagonistic activity with a 50% inhibitory concentration (IC) of 1.46 µM, which is 14.

Exploring Attachment Differences Across the Contexts of Sports and Academics: A Qualitative Exploration of Child and Parent Experiences.

This study aimed to explore the nature of contextual differences in child-parent attachment relationships and examine how these experiences relate to children's psychological outcomes. A theoretically informed qualitative study was conducted using semi-structured interviews with 15 participants across four groups of Taiwanese youths and parents, representing different contextual attachment combinations. Data were analyzed using a hybrid thematic analysis approach, integrating both inductive and deductive methods.

Intrauterine Adhesion-Induced Septated Amniotic Cavity: Ultrasonographic Findings in Second and Third Trimesters.

A 40-year-old woman who had obstetric history of one vaginal delivery and two surgical abortions to terminate early pregnancy received regular prenatal care without any systemic maternal diseases. During the detailed second trimester ultrasound, a homogenous adhesion-induced pseudocystic lesion of 8.6 × 7.

Parallel Bayesian Optimization of Thermophysical Properties of Low Thermal Conductivity Materials Using the Transient Plane Source Method in the Body-Fitted Coordinate.

The transient plane source (TPS) method heat transfer model was established. A body-fitted coordinate system is proposed to transform the unstructured grid structure to improve the speed of solving the heat transfer direct problem of the winding probe. A parallel Bayesian optimization algorithm based on a multi-objective hybrid strategy (MHS) is proposed based on an inverse problem.

Clinical Utility and Performance of the Traditional Chinese Version of the 4-As Test for Delirium Due to Traumatic Brain Injury.

Background: Delirium is a common symptom following a traumatic brain injury (TBI) that is often overlooked by healthcare professionals. Early detection of post-traumatic delirium is crucial to improving patient outcomes and quality of life. The four As Test (4AT: alertness, attention, abbreviated mental test-4, and acute mental changes) is a brief and rapid tool for delirium assessment with acceptable reliability and validity.
