Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Delayed Increases in Regional Brain Quinolinic Acid Follow Transient Ischemia in the Gerbil

, 1990
Excessive activity or release of excitatory amino acids has been implicated in the neuronal injury that follows transient cerebral ischemia. To investigate the metabolism of the endogenous excitotoxin, quinolinic acid, and its potential for mediating ...

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

Investigations on some metabolites of Tecoma stans Juss. callus tissue. Part II. Chromatographical analysis of alkaloid and quinone compounds

Acta Societatis Botanicorum Poloniae, 2015
Tecoma stans Juss. callus tissue grown on Murashige-Mei Lie Lin (M-L) and Murashige-Skoog (RT-k) medium supplemented with Tecoma alkaloid precursors like lysine, mevalonic acid lactone and quinolinic acid, were investigated for their alkaloid content by ...

Vitamin C and E Treatment Blocks Changes in Kynurenine Metabolism Triggered by Three Weeks of Sprint Interval Training in Recreationally Active Elderly Humans

Antioxidants, 2021
The kynurenine pathway (KP) is gaining attention in several clinical fields. Recent studies show that physical exercise offers a therapeutic way to improve ratios of neurotoxic to neuroprotective KP metabolites.

The genetic architecture of epilepsy across molecular mechanisms and clinical heterogeneity

Epilepsia Open, EarlyView.
Abstract Epilepsy comprises a highly heterogeneous group of neurological disorders unified by a persistent predisposition to recurrent seizures, yet driven by remarkably diverse genetic, molecular, and network‐level mechanisms. Advances in genomic technologies have revealed that epilepsy arises from a multilayered genetic architecture encompassing rare

Quinolinic acid-induced lesions of the rat striatum: quantitative autoradiographic binding assessment.

, 1998
Injection of the excitatory amino-acid analog quinolinic acid into the striatum of rats produces neuropathological and neurochemical alterations that are reminiscent of those observed in Huntington's disease. In the present study, we evaluated quinolinic
