Development of method for the mineral water catalase activity determination

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2015
Biological effects of mineral water depend not only on the chemical composition but also on the metabolic products of microbial cenosis. Among numerous microorganisms constituting the autochthonous microflora of mineral waters, we do evolve the ...

Plasma–Kinetic Coupling and Redox Mechanisms in the Degradation of Acid Red 51 by Atmospheric Corona Discharge

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the degradation of the xanthene dye Acid Red 51 (ARE‐51) using atmospheric‐pressure corona discharge plasma, integrating electrical characterization, optical emission spectroscopy (OES), kinetic modeling, and physicochemical analysis to establish a unified plasma–liquid interaction framework. A degradation efficiency of

Evaluation and Optimization of COD Removal Performance for a Domestic Wastewater Treatment Plant by Response Surface Methodology: The Case of Van Muradiye

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the performance of the Van Muradiye Domestic Wastewater Treatment Plant was evaluated with Response Surface Methodology (RSM). The effects of pH, conductivity, dissolved oxygen (DO), and suspended solids (SS) on the chemical oxygen demand (COD) removal efficiency were evaluated using samples collected from the plant's inlet and ...

Comparative Analysis of Salmonella typhimurium‐Induced Transcriptomic Changes in the Spleen of Beijing‐You Chickens and Guang Ming Broilers

open access: yesAnimal Research and One Health, EarlyView.
This study analyzed the spleen transcriptomes of different chicken breeds, identified key differentially expressed genes (EGR1, FOS, and DUSP1) that regulate resistance to Salmonella infection, and elucidated the underlying regulatory mechanisms, thereby providing new targets for disease‐resistant breeding in poultry.

A spectrophotometric method for calmodulin assay

open access: yes, 1988
The activity of calmodulin as an activator of cAMP phosphodiesterase was assayed. AMP was hydrolyzed by 5'-nucleotidase, and the adenosine formed was measured by both liquid scintillation counting and spectrophotometry at 265 nm.

Possible therapeutic repositioning of valproic acid: From epileptic seizures to acute kidney injury

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Valproic acid, an anticonvulsant, may be repositioned to prevent acute kidney injury due to ischemia followed by reperfusion. It preserves renal functions, electrolyte homeostasis and active sodium transport in kidney tubules, and blocks the onset of hypertension.
