in this research, the effect of different concentrations of chitosan (with low molecular weight) on in vitro proliferation of grape cultivar, ’bidaneh ghermez‘, was evaluated. 30 days after establishment, elongated shoots were cultured on the half strength murashige and skoog medium supplemented with 0.5 mg/l bap, 0.1 mg/l iba and different chitosan concentrations (0, 10, 20, 40 and 80 mg/l). t...

In the present research, mosquito fish Gambusia affinis have been exposed to lead chloride during 24, 48, 72 and 96 hours in order evaluate lethal 50 (LC50) concentration Its residue certain organs of fish. Usage EPA computer software based on Finney Probit Analysis method has statistically tested for data collected LC50 values G. if were found be 59.4, 55.9, 51.1 49. 0 mg/L, respectively. decr...

All-male giant freshwater prawns (AMGFPs) have been a popular crop cultivated in the Mekong Delta, Vietnam, due to their proven production efficiency compared all-female or mixed-sex prawn cultures. However, crucial water quality factors impacting AMGFP aquaculture yet be elaborately investigated. Two separate experiments were randomly arranged with three replicates evaluate effects of salinity...

cyclophosphamide (cp) is a mustard alkylating agent used in the treatment of a number of neoplastic diseases and as an immunosuppressant for the prevention of xenograft rejection. there are many reports that the teratogenic effects of cyclophosphamide can be prevented by application of antioxidant drugs and stimulation of the maternal immune system. also, there is some evidence that l-carnitine...

OBJECTIVE To study changes in indinavir exposure over time in HIV-1-infected children. MATERIALS AND METHODS Protease inhibitor (PI)-naive HIV-1-infected children were treated with indinavir, zidovudine and lamivudine. Steady-state plasma pharmacokinetic (PK) sampling was carried out as standard of care. The AUC(0-8) was targeted between 15 and 30 mg h/L. PK sampling was repeated after dosage...

We describe a single-run method for quantitating quinidine, procainamide, and N-acetylprocainamide, involving gas-liquid chromatography with a nitrogen-phosphorus selective detector. Within-run precision (CV) was 3% (x = 2 mg/L, n = 20), 6.9% (x = 4 mg/L, n = 10), and 1.5% (x = 8 mg/L, n = 8) for quinidine; 7.7% (x = 4 mg/L, n = 14), 1.6% (x = 8 mg/L, n = 16), and 2.3% (x = 12 mg/L, n = 12) for...

In vitro regeneration of shoots from leaf explants of the Paradise tree (Melia azedarach L.) was studied. Three different portions (proximal portion, distal portion and rachis of the leaflets) of three developmental stages (folded, young still expanding and completely expanded) of leaves of 10-15 year old plants of seven genotypes were cultured on Murashige and Skoog (1962) medium (MS) suppleme...

In this study, Plackett-Burman design was used to identify the most influential parameters affecting PUFA production by Kocuria sp. BRI 35 isolated from Antarctic water sample. Amongst 10 variables evaluated, magnesium chloride, protease peptone, glucose, and temperature were significant. Response surface methodology consisting of a central composite design was developed to study the interactio...
