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 ...

Programmed Interfacial Phase Separation for Spatiotemporal Fungicide Delivery via Tunable Micro/Nano Architectures

open access: yesAdvanced Science, EarlyView.
ABSTRACT Translating dynamic liquid‐liquid phase separation into robust solid‐state architectures remains a challenge in materials engineering. Here, we report a composition‐driven interfacial assembly strategy that couples supramolecular coacervation with metal‐phenolic coordination to engineer tunable fungicide carriers.

SR‐A3 Promotes USP18‐Mediated deISGylation of STING to Protect Against Myocardial Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
MI/RI is a major clinical challenge with high morbidity and mortality. This study demonstrates that SR‐A3 expression is downregulated in MI/RI, and its deletion exacerbates damage via the USP18/ISG15/STING axis, revealing SR‐A3 as a potential therapeutic target.

Isosteric Engineering of Enzymes: Overcoming Activity–Stability Trade‐Offs by Site‐Selective CH → N Substitutions

open access: yesAngewandte Chemie, EarlyView.
Coupling biosynthetic noncanonical amino acid production with genetic code expansion enables site‐specific incorporation of azatryptophans into PET‐degrading enzymes (PETases). By isosteric single‐atom editing of a conserved tryptophan, AzaPETases break the activity–stability trade‐off, delivering higher catalytic efficiency at elevated temperature and

A Biofabricated Human Acinus‐on‐a‐Chip Unveils Mechanotransductive Drivers of Ventilator‐Induced Lung Injury via Decoupling Volutrauma and Barotrauma

open access: yesAdvanced Science, EarlyView.
This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...

Delay of Cucumber Senescence and Life‐Extending Capabilities on Caenorhabditis elegans With the Postharvest Application of Sorbitol and Methyl Salicylate

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Methyl salicylate and sorbitol were taken as coating agents. Caenorhabditis elegans was taken as an animal model. The coated agents were applied in C. elegans. The life span study in C. elegans proves the authenticity of MS and SL. MS and SL extended the post‐harvest life of cucumber for 14 days.

Direct determination of nitrate in small volumes of natural surface waters using a simple spectrophotometric method

open access: yesReviews in Analytical Chemistry, 2012
A simple, sensitive and selective spectrophotometric method is proposed for rapid and direct determination of nitrate in small volumes of natural surface waters (maximum 2.0 ml), and optimal experimental conditions, along with other analytical parameters,

Multipathway modulation of neuroinflammation and oxidative stress by hesperidin in a rat single prolonged stress model of post‐traumatic stress disorder

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Single prolonged stress (SPS) induces post‐traumatic stress disorder (PTSD)‐like neuropathology characterized by oxidative stress, neuroinflammation, astrocytic reactivity, neuronal damage, and reduced neurotrophic support in the hippocampus, amygdala, and prefrontal cortex. Hesperidin counteracts these effects by attenuating lipid peroxidation and pro‐

Development and validation of a green spectrophotometric method for simultaneous determination of combined pharmaceutical dosage form (paracetamol and caffeine) using chemometrics technique in comparison with HPLC

open access: yesEclética Química
A green analytical method, a simple, fast, and cost-effective simultaneous spectrophotometric method using two chemometric techniques, the partial least square regression (PLS) and principal component regression (PCR), for determining a combination of ...

Sappanwood extract modulates hepatic structure–function in hepatomegaly and hepcidin related iron regulatory pathways in a phenylhydrazine induced hemolytic anemia rat model relevant to thalassemia

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Phenylhydrazine (PHZ) induces hemolytic anemia characterized by increased erythrocyte destruction and ineffective erythropoiesis, leading to hepcidin suppression through disruption of the BMP/SMAD signaling pathway. Reduced hepcidin levels enhance intestinal iron absorption and hepatic iron accumulation, leading to hepatic iron overload.
