Introduction: Macroprolactin may interfere with hormonal assay and falsely increase serum prolactin levels. Therefore, failure to identify macroprolactinemia can lead inappropriate investigations treatment in women already susceptible anxiety stress. The aim of this study was among childbearing age hyperprolactinemia.Materials methods: A cross-sectional conducted a tertiary care setting at the ...

Drought stress diminishes seedling germination and vigor by reducing water uptake, inhibiting plant growth development. Most of the pulse growing areas are under rainfed ecosystems, which significantly reduces crop yield. Melatonin, a growth-regulating compound, is widely used to mitigate negative effects abiotic stresses in pulses. With this background, laboratory experiment was conducted stan...

Nitric oxide (NO) is a active molecule involved in mediation of various biotic and abiotic stressinduced physiological responses in plants. In the present study, using SNP (sodium nitroprusside) as NO donor and cPTIO [2-(4-carboxypheny-4,4,5,5-tetramethylimidazoline-1-1oxyl-3-oxide, potassium salt] as specific NO scavenger, we examined the ability of exogenous NO to alleviate oxidative damage, ...

aqueous two-phase systems (atps) have  emerged as a powerful extraction method for the downstream processing of bio-molecules. the aim of this work was to investigate the possibility of utilizing atps for the separation of recombinant bacillus sphaericus phenylalanine dehydrogenase (phedh). polyethylene glycol (peg) and ammonium sulfate systems were selected for our experiment. the effect of di...

The purpose of the present study was to investigate the effect of polyethylene glycol (PEG) molecular weights (6000, 12000 and 20000) as solid dispersion (SD) carriers on the dissolution behavior of simvastatin. SDs with various drug : carrier ratios were prepared by solvent method and evaluated for dissolution rate. Differential scanning calorimetry (DSC), X-ray diffraction (XRD), infrared spe...

Aspergillus niger is a highly potent fungus used in the production of alkaline protease. Extra cellular alkaline protease was purified from A. niger in a twostep procedure involving ammonium sulphate precipitation and Sephadex G100 column chromatography. The molecular mass of the enzyme was determined to be 60 kDa by SDS-PAGE. The enzyme activity was also analyzed by zymogram with gelatin. The ...

Seeds of pearl millet (Pennisetum glaucum (L) R. Br.) from six provenances of Tunisia were subjected to germination and shoot and root length tests on filter paper treated with polyethylene glycol 6000 (PEG 6000) solutions made up to provide osmotic potentials of 0, -1 and -2 MPa. Mean germination percent for all provenances decreased about 73% in -2 MPa compared to control (0 MPa) treatment. O...
