the effects of different levels of nitrogen (100, 200, 300 and 400 mg/l) and potassium (125, 250 and 375 mg/l) on yield and leaf n and k concentrations of tomato were investigated in perlit culture using a factorial randomized design with three replications. the highest fruit yield was obtained with 200 mg/l n. higher levels of nitrogen decreased tomato yield. with increasing nitrogen concentra...

OBJECTIVE Evaluation of the efficacy and safety of a single oral dose of a 1200 mg sachet of chondroitin 4&6 sulfate (CS 1200) vs three daily capsules of chondroitin 4&6 sulfate 400 mg (CS 3*400) (equivalence study) and vs placebo (superiority study) during 3 months, in patients with knee osteoarthritis (OA). DESIGN Comparative, double-blind, randomized, multicenter study, including 353 patie...

Objective: To study the antiviral activity of lamivudine (3TC) plus zidovudine (ZDV), didanosine (ddI), or stavudine (d4T). Design: Randomized, placebo-controlled, partially double-blinded multicenter study. Setting: Adult AIDS Clinical Trials Units. Patients: Treatment-naive HIV-infected adults with 200–600 × 10 CD4 T lymphocytes/l. Interventions: Patients were openly randomized to a d4T or a ...

The hyper yield of peroxidase (POX) was investigated for a novel native Aspergillus niger strain identified by 18S RNA analysis. A. strains sequences were submitted to GenBank; IDs allotted MN611114.1 (BMB 17) and MN559756.1 (BMB-18). in combination showed enhanced activity (601.5 U/mL) solid-state fermentation comparison their individual activities. POX purified ammonium sulfate, size exclusio...

BACKGROUND AND PURPOSE Our aim was to evaluate whether increasing iodine concentration, at a constant total iodine dose, resulted in better brain tissue opacification in patients with acute stroke symptoms during their evaluation by first-pass CT perfusion (CTP). MATERIALS AND METHODS One hundred two patients presenting to the emergency department within 3 hours of onset of acute stroke sympt...

in order to study the physiological effects of some of the essential oils in comparison with 8-hydroxyquinoline in cut lisianthus flowers (eustoma grandiflorum l.), an experimental was conducted in a completely randomized design with three replications. traetments included 8-hydroxyquinoline, essential oil of australian cheesewood (pittosporum undudatum) and rosmary oil(rosmarinus officinalis) ...

The effects of pharmaceutical preparation of the unsaponifiable fraction of soybean (MRG), ursodeoxycholic acid (UDCA) and their combined treatment on lithogenic index (L. L) and gallstone dissolution were clinically investigated in gallstone patients. When seven patients with cholelithiasis were given UDCA alone at a daily dose of 300 or 400 mg during ca. 5 months, their L. L were cleary decre...

Introduction: Reverse osmosis (RO) is best known for its use in desalination (removing the salt from seawater to get fresh water), but since the early 1970s it has also been used to purify fresh water for medical, industrial, and domestic applications. The aim of this research was the performance study of reverse osmosis plants for water desalination in Bandar-Lengeh, Iran. Materials and Meth...
