The Journal of Physiology, EarlyView.Abstract figure legend There has been controversy about the structural (capillary) response of skeletal muscle to altered O2 status, involving decreased supply (hypoxia) or increased demand (activity). Here we demonstrate that seven days of activation of skeletal muscle by indirect electrical stimulation led to significant expansion of the capillary ...

Advanced Science, Volume 13, Issue 43, 3 August 2026.Hollow Co3O4/TiO2 heterojunctions are engineered for high‐throughput laser desorption/ionization mass spectrometry. The built‐in electric field drives efficient charge separation and photothermal conversion, while the hierarchical mesoporous network enables robust salt and protein tolerance.

Carnosine as a histidine source: Transport and hydrolysis of exogeneous carnosine by rat intestine.
Journal of Nutritional Science and Vitaminology, 1985 Transport and metabolism of L-carnosine (beta-alanyl-L-histidine) were studied in rat small intestine. Carnosine administered orally was found in rat serum as well as small intestine and liver, followed by an increase of histidine. At ten minutes after carnosine infusion per os, the carnosine content of the hepatic portal vein increased with the dose ...

Determinants of muscle carnosine content [PDF]
Amino Acids, 2012 The main determinant of muscle carnosine (M-Carn) content is undoubtedly species, with, for example, aerobically trained female vegetarian athletes [with circa 13 mmol/kg dry muscle (dm)] having just 1/10th of that found in trained thoroughbred horses.

Zinc, Carnosine, and Neurodegenerative Diseases [PDF]
Nutrients, 2018 Zinc (Zn) is abundantly present in the brain, and accumulates in the synaptic vesicles. Synaptic Zn is released with neuronal excitation, and plays essential roles in learning and memory. Increasing evidence suggests that the disruption of Zn homeostasis is involved in various neurodegenerative diseases including Alzheimer’s disease, a vascular type of

Quantitative Guanidinium CEST‐Based pH Mapping at 3 T in Healthy and Pathological Muscle
NMR in Biomedicine, Volume 39, Issue 8, August 2026.Chemical exchange saturation transfer (CEST) enables high‐resolution pH mapping by measuring the exchange rate between guanidinium and water protons. The current method is based on the Z‐spectra fitting with Bloch–McConnell (BM) equations and allows us to detect pH variations on the order of 0.02 pH units in the very restrained pathophysiological pH ...
