Sodium thiosulfate treatment rescues hyperglycaemia‐induced pronephros damage in zebrafish by upregulating nitric oxide signalling

The Journal of Physiology, EarlyView.
Abstract figure legend Sodium thiosulfate (STS) rescues the pronephros phenotype of pdx1 morphants through compensatory upregulation of nitric oxide (NO) metabolism. Zebrafish larvae injected with a control morpholino show the typical pronephros structure at 48 h post‐fertilization (hpf) with and without STS treatment.

Identification of a Histidine Metal Ligand in the \u3cem\u3eargE\u3c/em\u3e-Encoded \u3cem\u3eN\u3c/em\u3e-Acetyl-L-Ornithine Deacetylase from \u3cem\u3eEscherichia coli\u3c/em\u3e [PDF]

, 2013
The H355A, H355K, H80A, and H80K mutant enzymes of the argE-encoded N-acetyl-L-ornithine deacetylase (ArgE) from Escherichia coli were prepared, however, only the H355A enzyme was found to be soluble. Kinetic analysis of the Co(II)-loaded H355A exhibited

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

, 2013
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

L-Phenylalanine Transport in Saccharomyces cerevisiae: Participation of GAP1, BAP2, and AGP1 [PDF]

, 2014
We focused on the participation of GAP1, BAP2, andAGP1 in L-phenylalanine transport in yeast. In order to study the physiological functions of GAP1, BAP2, and AGP1 in L-phenylalanine transport, we examined the kinetics, substrate specificity, and ...

Targeting Tumor Dormancy and Recurrence: Molecular Mechanisms and Peptide Therapeutic Delivery

MedComm – Oncology, Volume 5, Issue 1, March 2026.
This review summarizes the molecular mechanisms that regulate tumor dormancy and its role in cancer recurrence, with emphasis on immune evasion, extracellular matrix remodeling, metabolic regulation and angiogenic switching. It further discusses emerging peptide–based therapeutic strategies aimed at detecting, modulating, and eliminating dormant tumor ...

Design of a bioreactor to study the role of red blood cells in the transport of nitric oxide in the microcirculation [PDF]

, 2007
Nitric oxide (NO) plays an important role in physiological functions like vasodilation, neurotransmission, and inhibition of platelet aggregation. The endothelium-derived NO diffuses into the vascular lumen where it interacts with flowing blood as well ...

Effect of L-arginine on the growth of Plasmodium falciparum and immune modulation of host cells

Journal of Vector Borne Diseases, 2017
Background & objectives: Malaria is a life-threatening disease caused by Plasmodium parasites. The life-cycle of Plasmodium species involves several stages both in mosquito and the vertebrate host. In the erythrocytic stage, Plasmodium resides inside the

Dried Watermelon Rind Mash Diet Increases Plasma L-Citrulline Level in Chicks

The Journal of Poultry Science, 2019
Heat stress is an increasing concern in poultry industry as it can cause a rise in the body temperature of chickens. Recently, we reported that l-citrulline (l-Cit) is a potential hypothermic agent that could improve thermotolerance in chicks. However, synthetic l-Cit has not yet been approved for inclusion in animal diets.
