Rose Bengal photosensitized flow injection chemiluminescence method is reported using luminol-Cu(II) for the determination of vitamins A and C in pharmaceutical formulations. The reaction is based on the enhancement effect of analyte in the production of anion radicals of Rose Bengal (RB (•-)) which rapidly interact with dissolved oxygen and generate superoxide anions radicals (O2 (•-)) and hyd...

BACKGROUND To investigate the effect of pectinase-treated Panax ginseng (GINST) in cellular and male subfertility animal models. METHODS Hydrogen peroxide (H2O2)-induced mouse spermatocyte GC-2spd cells were used as an in vitro model. Cell viability was measured using MTT assay. For the in vivo study, GINST (200 mg/kg) mixed with a regular pellet diet was administered orally for 4 mo, and the...

the aim of our work was to compare cytotoxic and membrane-damaging effects of o. majorana l. essential oil and linalool on hep g2 and to investigate their possible protective (antioxidant) effects against h2o2 induced membrane damage. the oils were investigated by gc and gc-ms and antioxidant activity was evaluated by dpph and -carotene–linoleic acid assays. assessment of cell viability was ma...

Mentha piperita L. (peppermint) possesses antimicrobial properties, but little is known of its ability to modulate macrophages. Macrophages are essential in bacterial infection control due to their antimicrobial functions and ability to link the innate and adaptive immune responses. We evaluated the effects of the peppermint leaf hydroalcoholic extract (LHAE) on cultured murine peritoneal macro...

The structure of the title salt, C(12)H(12)N(+)·HSeO(4) (-), consists of infinite parallel two-dimensional planes built of 4-benzyl-pyridinium and hydrogen selenate ions that are mutually connected by strong O-H⋯O and N-H⋯O hydrogen bonds. There are no contacts other than normal van der Waals inter-actions between the layers.

In the title mol-ecular salt, C(4)H(10)NO(+)·C(4)H(5)O(6) (-), the morpholinium cation adopts a chair conformation. The conformation of the C-C-C-C backbone of the monotartrate anion is close to anti [torsion angle = 173.18 (17)°], which is supported by two intra-molecular O-H⋯O hydrogen bonds. In the crystal, the components are linked by N-H-O and O-H-O hydrogen bonds, generating (001) sheets.

In this work a combined molecular dynamics simulation and dynamically corrected transition-state theory (dcTST) study was performed to investigate the effect of interpenetration (catenation) on hydrogen diffusion in metal-organic frameworks (MOFs) as well as their relationships. The results on 10 isoreticular MOFs (IRMOFs) with and without interpenetration show that catenation can reduce hydrog...

ZnAlCO3 hydrotalcite materials modified by Cu2+ ions were synthesized the co-precipitation method according to molar ratios of (Cu2+ + Zn2+):Al3+ as 7:3. Thus, contain various from 0–3.5 in samples. The characterized X-ray diffraction pattern (XRD), FT–IR, EDS, SEM, N2 adsorption/desorption isotherm (BET), and UV–Vis DRS spectrum. a layered double hydroxide structure—such hydrotalcite. specific...
