KaMLs for Predicting Protein p Values and Ionization States: Are Trees All You Need?
J Chem Theory Comput

Department of Pharmaceutical Sciences, University of Maryland School of Pharmacy, Baltimore, Maryland 21201, United States.
Despite its importance in understanding biology and computer-aided drug discovery, the accurate prediction of protein ionization states remains a formidable challenge. Physics-based approaches struggle to capture the small, competing contributions in the complex protein environment, while machine learning (ML) is hampered by the scarcity of experimental data. Here, we report the development of p ML (KaML) models based on decision trees and graph attention networks (GAT), exploiting physicochemical understanding and a new experiment p database (PKAD-3) enriched with highly shifted p's.

Rotator cuff tendon injuries often lead to shoulder pain and dysfunction. Traditional treatments such as surgery and physical therapy can provide temporary relief, but it is difficult to achieve complete healing of the tendon, mainly because of the limited repair capacity of the tendon cells. Therefore, it is particularly urgent to explore new treatment methods.

College of Physical Education and Health, Guangxi Normal University, Guilin, China.
Objective: This study aims to assess the relationship between modifiable dementia risk factors and both dementia and cognitive decline.
Methods: Data were obtained from the Health and Retirement Study (HRS) [2008-2020], the China Health and Retirement Longitudinal Study (CHARLS) [2011-2020], and the English Longitudinal Study of Ageing (ELSA) [2010-2020]. After adjusting for confounding factors, multivariable logistic regression was utilized to analyze the relationship between modifiable dementia risk factors and dementia, while multivariable linear regression was employed to examine the relationship between these risk factors and cognitive decline.
The health effect of relaxing entry regulation for private hospitals and its nonlinear characteristics: evidence from China.

China Institute of Regulation Research, Zhejiang University of Finance and Economics, Hangzhou, China.
Introduction: Relaxing entry regulation for private hospitals and fostering competition in the healthcare market are crucial prerequisites for addressing the diverse healthcare demands of the population and promoting the development of a Healthy China. This study aims to comprehensively evaluate the health effect of relaxing entry regulation for private hospitals and to examine its nonlinear characteristics.
Methods: Using panel data from 31 provinces in mainland China, this study employs a fixed effects panel data model to investigate the health effect of relaxing entry regulation for private hospitals.
A novel small RNA regulates Locus of Enterocyte Effacement and site-specific colonization of enterohemorrhagic O157:H7 in gut.

College of Public Health, North China University of Science and Technology, Tangshan, China.
Enterohemorrhagic (EHEC) is a contagious foodborne pathogen that specifically colonizes the human large intestine, which is regulated by different environmental stimuli within the gut. Transcriptional regulation of EHEC virulence and infection has been extensively studied, while the posttranscriptional regulation of these processes by small RNAs (sRNAs) remains not fully understood. Here we present a virulence-regulating pathway in EHEC O157:H7, in which the sRNA EvrS binds to and destabilizes the mRNA of Z2269, a novel transcriptional regulator.
