Modeling Effects of Rumination on Free Recall Using ACT‐R

Topics in Cognitive Science, EarlyView.
Abstract Ruminative thinking, characterized by a recurrent focus on negative and self‐related thought, is a key cognitive vulnerability marker of depression and, therefore, a key individual difference variable. This study aimed to develop a computational cognitive model of rumination focusing on the organization and retrieval of information in memory ...

Psychological stress catalyses free radical–mediated activation of coagulation in humans

The Journal of Physiology, EarlyView.
Abstract figure legend This study provides the first in vivo evidence that acute psychological stress triggers systemic free radical formation and prothrombotic remodelling of blood clot microstructure. By inducing stress in healthy participants, we observed a significant increase in oxidative stress (A•−), a shortening of the intrinsic pathway of ...

Screening and application of aptamers to Staphylococcus aureus Toxic Shock Syndrome Toxin-1 [PDF]

, 2016
摘要 目的：金黄色葡萄球菌(Staphylococcusaureus)分泌的毒性休克综合征毒素-1(ToxicShockSyndromeToxin-1，TSST-1)引发中毒性休克综合征(ToxicShockSyndrome，TSS)，通过激活T淋巴细胞使其活化、增殖，引起强烈的免疫应答。目前针对TSST-1本身的治疗手段不多，合成寡核苷酸文库和亲和力筛选作为获得高亲和力、高特异性适配体(Aptamer)的一种方便、快捷、有效的方法。本研究利用指数富集的配体系统进化技术 ...

Does Cardiorespiratory Fitness Predict the Physiological and Psychological Stress Response to a Mathematics Exam in Secondary High School Students?

European Journal of Sport Science, Volume 26, Issue 5, May 2026.
ABSTRACT School is widely recognized as one of the primary sources of stress among adolescents. While some studies employing laboratory‐based stressors have suggested that adolescents with better cardiorespiratory fitness (CRF) may exhibit lower stress reactivity to psychosocial stressors, research based on real‐life stressors is lacking. Therefore, we

Latitude Dictates Global Marine Diatom Dynamics: Insights From 25 years of Satellite Data

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Marine diatoms are key players in global biogeochemical cycles, yet their spatiotemporal dynamics and the underlying drivers remain poorly understood. Here, we developed a novel remote sensing model and utilized 25 years of global satellite data to investigate marine diatom biomass.

Environmental factors affecting toxic shock syndrome toxin-1 (TSST-1) synthesis [PDF]

Journal of Medical Microbiology, 1987
The production of toxic shock syndrome toxin-1 (TSST-1) was studied in batch and continuous culture of Staphylococcus aureus strain 1169 in a carbohydrate-free chemically defined medium (CDM). In continuous culture oxygen- and arginine-limitation were required for steady-state TSST-1 synthesis. Aeration suppressed toxin synthesis.
