Oxidative stress is oxidative damage caused by free radicals and reactive oxygen species (ROS). These ROS can cause to cellular components, including membrane lipids, receptors, enzymes, proteins, nucleic acids. It would eventually lead cell apoptosis the appearance of certain pathological conditions. This work investigates antioxidant potentials chamomile extract in vitro evaluating activity scavenge 2,2-Diphenyl-1-picrylhydrazyl (DPPH), also vivo investigating its effects on stress-induced...
Abstract This article reports the preparation of new mesoporous triazine‐based organic polymers and their characterization. The were synthesized via a nucleophilic condensation reaction between cyanuric chloride bisphenols or aromatic diamine linkers. As result, two types prepared: triazine‐ether triazine‐amine polymers. reveal nature with surface area values ranging 345 1275 m 2 g −1 mesopore volume 0.273 1.03 cm 3 . These determined from argon gas isotherms at 87 K. pore size distribution...
Medicinal plants have been used for longtime treatment of many illnesses. Many were described in folk heritage to anti-inflammatory activity treat digestive diseases. In this study, thirteen commonly by Jordanian folks disorders investigated find a connection between their contents and activities relationship with assigned use. The ethanolic extracts the tested Total Phenolic Content (TPC), Tannin (TTC), Flavonoid (TFC) antioxidants using 2,2-diphenyl-1-picrylhydrazyl (DPPH) 2,2'-azino-bis...
This study reports the synthesis and characterization of novel per-fluorinated organic polymers with azo- azomethine-based linkers using nucleophilic aromatic substitution. The reveal variations in fluorine content via incorporation decafluorobiphenyl hexafluorobenzene linkers, which enhanced their hydrophobic nature. rich were slightly soluble THF have shown molecular weights between 4886 to 11948 g/mol. All exhibit thermal stability range 350-500°C, varying depending on nitrogen content....
In this report, an open-chain ether-linked polymer (PE-AF) has been prepared via one-step co-condensation polymerization of 1,4-dibromo-2,5-difluorobenzene with bisphenol AF. The new shown a good solubility in non-polar solvents, thermal stability (up to 300 °C), high char residue limiting oxygen index (LOI) 33.5, surface morphology random fluffy-like texture, and non-porosity nature area (SA) 35 m2g−1. Tailoring these properties achieved by considering post-modification on the Bromo-sites...
This study reports on the synthesis and characterization of novel perfluorinated organic polymers with azo- azomethine-based linkers using nucleophilic aromatic substitution. The were synthesized via incorporation decafluorobiphenyl hexafluorobenzene diphenols in basic medium. variation allowed different fluorine nitrogen contents. rich slightly soluble THF have shown molecular weights ranging from 4886 to 11,948 g/mol. All exhibit thermal stability range 350-500 °C, which can be attributed...
In this report, a synergetic computational and experimental studies were demonstrated on examples of poly-imine polymers; P(PI-IPI) P(PIOH-IPI) to explore the role hydroxyl substituent their sensing electronic properties. The polymer bearing OH-group ortho -position imine-bond, while structure reveal imine-bond only. property polymers was investigated via UV-vis absorption in different solvents, acidic basic solutions. Both have shown significant behavior medium, unpronounced noticed case...
