Investigations of segmental arterial stiffness in a cross-sectional study on young adult male trained swimmers, cyclists, and non-trained men.

Contrary to cardiovascular risk reductions by aerobic exercise, arterial stiffness, as assessed by brachial-ankle pulse wave velocity (PWV), is higher in swimmers and controls than in other aerobically trained individuals. The main muscles actively recruited in swimming are in the upper limbs, so this study aimed to investigate heart-brachial PWV in swimmers and to compare arterial stiffness indices between modes and measurement localities. Subjects comprised 60 individuals (18-22 years), including 20 untrained controls (Con), 20 aerobically trained cyclists (Aero), and 20 swimmers (Swim).

Distinct network patterns emerge from Cartesian and XOR epistasis models: a comparative network science analysis.

Background: Epistasis, the phenomenon where the effect of one gene (or variant) is masked or modified by one or more other genes, significantly contributes to the phenotypic variance of complex traits. Traditionally, epistasis has been modeled using the Cartesian epistatic model, a multiplicative approach based on standard statistical regression. However, a recent study investigating epistasis in obesity-related traits has identified potential limitations of the Cartesian epistatic model, revealing that it likely only detects a fraction of the genetic interactions occurring in natural systems.

Impact of Coronavirus Disease 2019 Emergency Declarations on Surgeries for Deep Neck Infection Incidence in Japan.

Introduction: Deep neck infections are lethal diseases; however, factors related to their prevention remain unclear. The national emergency declaration in April 2020, in response to COVID-19, spurred widespread adoption of nonpharmaceutical interventions (NPIs) such as hand washing, mask wearing, and social distancing.

Methods: This retrospective cohort study examines the impact of these interventions on the incidence of deep neck infections in Japan through interrupted time series analysis using National Database of Health Insurance Claims and Specific Health Checkups of Japan Open Data.

The cortical areas processing periodontal ligament nociception in mice.

Objectives: Toothaches are often poorly localized. Although periodontal pain is better localized, it can spread to other areas. Ultimately, the cerebral cortex processes nociception, with somatotopic organization possibly playing a role in localizing the origin.
