Impact of 14 days of head‐down bed rest and an exercise countermeasure on skeletal muscle atrophy, proteome and circulatory cytokines in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Prolonged bed rest and immobilization have deleterious effects on skeletal muscle mass and function, especially in older adults. These can lead to reduced physical capacity and quality of life. Previous experiments in younger individuals show that exercise can mitigate these effects, but evidence remains scarce and inconclusive in older adults.

Musculoskeletal decay and bone–muscle crosstalk during physical disuse: Mechanisms and integrated countermeasures

open access: yesExperimental Physiology, EarlyView.
Abstract Older adults experience a markedly increased risk of falls and fractures following hospital discharge, largely due to the rapid musculoskeletal deterioration associated with bed rest. Although age‐related muscle and bone loss typically develops gradually, acute physical inactivity accelerates key biological processes underlying sarcopenia and ...

Temporal Dilution: Chemotherapy, Capitalism, and the Making of Cancer Time in Colombia

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 4, December 2026.
ABSTRACT Through the ethnographic case of a man undergoing chemotherapy for prostate cancer at a hospital in Colombia, this article examines how chemotherapy schedules make toxicity clinically manageable while imposing rhythms that many patients cannot sustain. It develops an analytic framework centered on three interrelated temporal dynamics: temporal

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5875-5891, November 2026.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.

Interaction With Surface Spins as a Contribution to Nuclear Magnetic Relaxation of Liquids Adsorbed in Mesoporous Materials

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 11, Page 917-929, November 2026.
Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,
