Regulation of capillary hemodynamics by KATP channels in resting skeletal muscle

open access: yesPhysiological Reports, Volume 9, Issue 8, April 2021., 2021
Superfusion of the rat spinotrapezius muscle with the sulfonylurea glibenclamide (GLI) was used to locally inhibit KATP channels in vivo. GLI reduced both red blood cell (RBC) flux and velocity thereby impairing perfusive microvascular O2 transport and lengthening RBC capillary transit times, respectively.

Oxygen transmission rate in American oak barrel staves used for wine aging: Influence of wood macrostructure

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7844-7857, October 2026.
Abstract Background Oak barrels are widely used in wine and spirit aging, where oxygen transmission plays a key role in the development of chemical and sensory properties. In cooperage, stave selection is traditionally based on grain width; however, the extent to which grain and wood macrostructure determine oxygen transmission under barrel conditions ...

Effects of Acclimation Temperature on Responses of Blackfoot Pāua (Haliotis iris) to Acute Temperature Change, Reduced Salinity and Progressive Hypoxia

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Effects of acclimation temperature with acute temperature, reduced salinity or lowered dissolved oxygen are significant stressors to physiological and biological responses of adult Pāua. Pāua have a limited ability to acclimate to temperatures above 18 °C.

Bias‐Triggered Conductivity Relaxation (BCR): A Unique Tool to Simultaneously Investigate Thermodynamics, Kinetics, and Electrostatic Effects of Oxygen Reactions in MIEC Thin Films

open access: yesAdvanced Materials, Volume 38, Issue 43, 3 August 2026.
This work develops bias‐triggered conductivity relaxation as a novel technique to study oxygen reactions in mixed ionic‐electronic conducting thin films by integrating electrochemical titration and electrical conductivity relaxation to achieve synchronous multi‐parameter characterization, providing simultaneous electronic, ionic, and extraordinarily ...

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 5, Page 498-507, June 2026.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 14, April 10, 2026.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

On the shape of the radiation survival curve in tumor spheroids: The role of oxygen heterogeneity

open access: yesMedical Physics, Volume 53, Issue 4, April 2026.
Abstract Background The shape of cell survival curves at the tissue level remains an open question in radiobiology. While homogeneous cell populations (so‐called single cells) typically exhibit an exponential decrease in survival with increasing dose, it is unclear whether this behavior persists in multicellular systems, where oxygen and nutrient ...

Organ Transplantation: Current Status, Challenges, and Future Prospects

open access: yesMedComm, Volume 7, Issue 1, January 2026.
Organ transplantation success relies on precise modulation of the alloimmune response across distinct temporal phases of rejection. Hyperacute rejection results from preformed antibodies activating complement and causing thrombosis, while acute rejection involves T cell‐ and antibody‐mediated mechanisms that drive endothelial activation and ...

Simulated Abrupt Shifts in Aerobic Habitats of Marine Species in the Past, Present, and Future

open access: yesEarth's Future, Volume 12, Issue 4, April 2024.
Abstract The physiological tolerances of marine species toward ambient temperature and oxygen can jointly be evaluated in a single metric: the metabolic index. Changes therein characterize a changing aerobic habitat tailored to species‐specific thermal and hypoxia sensitivity traits. If the geographical limits of marine species as indicated by critical
