New Fluorescent Nanosensor for Determination of Diazepam Using Molecularly Imprinted Mn-doped ZnS Quantum Dots.

In this study, molecularly imprinted Mn-doped ZnS quantum dots were used as nanosensors to determine diazepam and its metabolites. Mn-doped ZnS quantum dots (QDs) capped with L-cysteine were prepared using a sodium thiosulfate precursor and characterized by various methods. Methacrylic acid was used as a precursor for the synthesis of MIP Mn-doped ZnS QDs and then used to measure diazepam in various samples.

The Combinatory Effect of Spirulina Supplementation and Resistance Exercise on Plasma Contents of Adipolin, Apelin, Ghrelin, and Glucose in Overweight and Obese Men.

Methods: The current investigation was conducted in a single-blind and quasiexperimental fashion. Sixty overweight and obese men (BMI > 25) ranging in age from 30 to 55 years were purposefully selected and randomly assigned to one of four groups: training plus spirulina (T+S), training plus placebo (T+P), spirulina (S), or placebo (P). For eight weeks, the (S) and (P) groups consumed two 500 mg spirulina and placebo capsules daily, respectively.

Therapeutic and Preventive Effects of Aqueous Extract of Date Palm (Phoenix dactylifera L.) Pits on Ethylene Glycol-Induced Kidney Calculi in Rats.

Introduction: Urinary tract stones are one of the most common diseases in the urinary tract. Lack of kidney stone treatment causes irreparable damages to the kidneys, which has many harmful effects. Date palm pits are recommended in traditional medicine as an effective drug in the treatment of kidney stones.

The Effects of Aqueous Extract of Eryngium Campestre on Ethylene Glycol-Induced Calcium Oxalate Kidney Stone in Rats.

Purpose: This study aimed to evaluate the anti-inflammatory effect of E. campestre using the aqueous extracts, obtained from the aerial parts, on Ethylene Glycol (EG)-induced calcium oxalate kidney stone in rats.

Materials And Methods: 64 male Wistar rats were randomly divided into 8 groups.

Therapeutic Effects of Aqueous Extracts of Cerasus Avium Stem on Ethylene Glycol- Induced Kidney Calculi in Rats.

Purpose: To investigate the therapeutic effects of the aqueous extract of Cerasus Avium stem on kidney calculi.

Materials And Methods: In this experimental study, forty-eight (48) male Wistar rats were randomly allocated into six (6) groups and were studied during a 30 day period. Group A served as normal control and Group B received 1% ethylene glycol in drinking water (EG group).

A new amperometric biosensor based on Fe3O4/polyaniline/laccase/chitosan biocomposite-modified carbon paste electrode for determination of catechol in tea leaves.

In the present study, a new biosensor based on laccase from Paraconiothyrium variabile was developed for catechol. The purified enzyme entrapped into the Fe3O4/polyaniline/chitosan (Fe3O4/polyaniline (PANI)/chitosan (CS)) biocomposite matrix film without the aid of other cross-linking reagents by a one-step electrodeposition on the surface of carbon paste electrode (CPE). The formed layer of biocomposite was characterized with scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV).

A nanocomposite/crude extract enzyme-based xanthine biosensor.

A novel amperometric biosensor for xanthine was developed based on covalent immobilization of crude xanthine oxidase (XOD) extracted from bovine milk onto a hybrid nanocomposite film via glutaraldehyde. Toward the preparation of the film, a stable colloids solution of core-shell Fe3O4/polyaniline nanoparticles (PANI/Fe3O4 NPs) was dispersed in solution containing chitosan (CHT) and H2PtCl6 and electrodeposited over the surface of a carbon paste electrode (CPE) in one step. Scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectrophotometry, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) were used for characterization of the electrode surface.

Auraptene from Ferula szowitsiana protects human peripheral lymphocytes against oxidative stress.

The antigenotoxicity effects of auraptene on DNA damage in human peripheral lymphocytes were studied using alkaline single cell gel electrophoresis. Auraptene at concentrations of 5, 10, 25, 50, 100, 200 and 400 microM was tested under simultaneous treatment with 25 microM H(2)O(2). The data are expressed as % tail DNA and compared with ascorbic acid at concentrations of 25, 50, 100, 200 and 400 microM.

Antigenotoxic effects of the disulfide compound persicasulfide A (PSA) on rat lymphocytes exposed to oxidative stress.

The antigenotoxic effect of persicasulfide A (PSA) from Ferula persica on DNA damage induced by hydrogen peroxide (H2O2) was evaluated using single cell gel electrophoresis (SCGE). PSA was extracted from F. persica, characterized by NMR and its antioxidant/antigenotoxic effects were investigated.

Evaluation of antigenotoxicity effects of umbelliprenin on human peripheral lymphocytes exposed to oxidative stress.

The protective properties of a prenylated coumarin, umbelliprenin (UMB), on the human lymphocytes DNA lesions were tested. Lymphocytes were isolated from blood samples taken from healthy volunteers. DNA breaks and resistance to H(2)O(2)-induced damage were measured using a single-cell microgel electrophoresis technique under alkaline conditions (comet assay).
