Film Effectiveness Downstream the Trenches with Tilted Target Wall

open access: yesInternational Journal of Rotating Machinery, Volume 2022, Issue 1, 2022., 2022
Film cooling is a commonly‐accepted effective way to protect the gas turbine hot sections from the high temperature products of the combustion chamber. Numerous film hole geometries have been the subject of investigation by many researchers over the past three decades with the aim of keeping the target wall under the maximum allowable temperature with ...

Valmet Chiral Schiff‐Base Ligands And Their Copper(II) Complexes as Organo, Homogeneous and Heterogeneous Catalysts for Henry, Cyanosilylation and Aldol Coupling Reactions

open access: yesChemCatChem, Volume 13, Issue 21, Page 4634-4644, November 8, 2021., 2021
Immobilization: L‐ and D‐valmet ligands prepared from the condensation of o‐vanillin and L‐, respectively, D‐methionine exhibit a different catalytic behavior affording asymmetric Henry condensation, cyanosilylation reaction after complexation with copper or the Aldol reaction after the immobilization of these complexes onto GO.

High‐throughput determination of oxygen dissociation curves in a microplate reader—A novel, quantitative approach

open access: yesPhysiological Reports, Volume 9, Issue 16, August 2021., 2021
Hemoglobin oxygen dissociation curves are measured using a modified, commercial 96‐well plate with an integrated unidirectional gas‐flow system specifically adapted for use in fluorescence microplate readers. Up to 92 samples of whole or hemolyzed, buffered or unbuffered blood, including appropriate controls or internal standard hemoglobin solutions ...

Temperature but not ocean acidification affects energy metabolism and enzyme activities in the blue mussel, Mytilus edulis

open access: yesEcology and Evolution, Volume 11, Issue 7, Page 3366-3379, April 2021., 2021
Our study demonstrates that adult Mytilus edulis from Gulf of Maine, one of the hot spots for global climate change, are metabolically resilient to the moderate acidification scenarios for the next 100–300 years but responsive to warming as seen in changes in metabolic rate, energy reserves, metabolite profiles, and enzyme activities.

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.

Mathematical predictions of oxygen availability in micro‐ and macro‐encapsulated human and porcine pancreatic islets

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 108, Issue 2, Page 343-352, February 2020., 2020
Abstract Optimal function of immunoisolated islets requires adequate supply of oxygen to metabolically active insulin producing beta‐cells. Using mathematical modeling, we investigated the influence of the pO2 on islet insulin secretory capacity and evaluated conditions that could lead to the development of tissue anoxia, modeled for a 300 μm islet in ...

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 ...

Complex Assessment of the Incidence and Risk Factors of Delirium in a Large Cohort of Cardiac Surgery Patients: A Single‐Center 6‐Year Experience

open access: yesBioMed Research International, Volume 2013, Issue 1, 2013., 2013
Background. Previous reports provided inconsistent data on the occurrence of postoperative delirium and emphasized its considerable impact on outcome. This study sought to evaluate the incidence and predictors of delirium, together with its relation to cerebral ischemia in a large cohort of cardiac surgery patients in a tertiary high‐volume center ...

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 ...
