Article Abstract
Background: The Differential Adhesion Hypothesis (DAH) is a theory of the organization of cells within a tissue which has been validated by several biological experiments and tested against several alternative computational models.
Results: In this study, a statistical approach was developed for the estimation of the strength of adhesion, incorporating earlier discrete lattice models into a continuous marked point process framework. This framework allows to describe an ergodic Markov Chain Monte Carlo algorithm that can simulate the model and reproduce empirical biological patterns. The estimation procedure, based on a pseudo-likelihood approximation, is validated with simulations, and a brief application to medulloblastoma stained by beta-catenin markers is given.
Conclusion: Our model includes the strength of cell-cell adhesion as a statistical parameter. The estimation procedure for this parameter is consistent with experimental data and would be useful for high-throughput cancer studies.

The study objective was to investigate the tibia fractures morphology depending on the position of victim at the time of injury when falling from height. The article presents the results of mathematical statistics which was carried out to justify scientifically the expert approach to reconstruction of accident circumstances in a fall from height with various landing options. The study results can be used to determine the position of the victim's body at the moment of landing, as well as to specify the height of fall.

J Med Internet Res
September 2025
School of Pharmacy, Sungkyunkwan University, Gyeonggi-do, Republic of Korea.
Background: Owing to the unique characteristics of digital health interventions (DHIs), a tailored approach to economic evaluation is needed-one that is distinct from that used for pharmacotherapy. However, the absence of clear guidelines in this area is a substantial gap in the evaluation framework.
Objective: This study aims to systematically review and compare the economic evaluation literature on DHIs and pharmacotherapy for the treatment of depression.
A Risk Prediction Tool for Invasive Melanoma.
JAMA Dermatol
September 2025
Department of Population Health, QIMR Berghofer Medical Research Institute, Herston, Queensland, Australia.
Importance: Increasingly, strategies to systematically detect melanomas invoke targeted approaches, whereby those at highest risk are prioritized for skin screening. Many tools exist to predict future melanoma risk, but most have limited accuracy and are potentially biased.
Objectives: To develop an improved melanoma risk prediction tool for invasive melanoma.
What are the key targets to improve quality of life among MSM living with HIV on antiretroviral therapy? A network analysis.
Qual Life Res
September 2025
Department of Epidemiology, School of Public Health, Cheeloo College of Medicine, Shandong University, 44 West Wenhua Road, Jinan, 250012, Shandong, China.
Purpose: The study aimed to assess the interconnection of quality of life (QoL) variables and identify key areas for which interventions could improve QoL among men who have sex with men (MSM) living with HIV on antiretroviral therapy (ART).
Methods: A cross-sectional study was conducted in Jinan of Shandong Province, between October to December 2020. Undirected network analyses were conducted to examine and visualize the interconnections between QoL variables among MSM living with HIV.
