Background and objectives: Aerial parts and roots of Astrodaucus persicus (Apiaceae), a native plant of Iran, were investigated. The existence of compounds with 1, 3-benzodiaxole structures has been confirmed in roots of this plant and different benzodioxole compounds have shown antimalarial and cytotoxic activities; therefore, present study has evaluated the antimalar...

A method based on Electrical Capacitance Tomography (ECT) and an improved Least Squares Support Vector Machine (LS-SVM) is proposed for void fraction measurement of oil-gas two-phase flow. In the modeling stage, to solve the two problems in LS-SVM, pruning skills are employed to make LS-SVM sparse and robust; then the Real-Coded Genetic Algorithm is introduced to solve the difficult problem...

backgrand: the genus ajuga , belongs to lamiaceae family, is one of the exclusive subspecies in the flora of iran. the plants of this genus are used traditionally for treatment of joints pain, gout, jaundice, and as insecticide. methods: larvicidal activity of methanol 80% extract and partition fractions of hexane, chloroform, and ethyl acetate obtained from aerial parts of ajuga chamaecistus s...

partially purified antigenic fractions of leishmania major promastigotes were obtained by sodium dodecyl sulfate (sds-page) and electro-elution. three isolated protein fractions designated as frac tions (fr.) 1, 2, and 3 correspond to 40-60, 60-80, 80-100 kilodalton (kda) respectively. they were used for immunization of balb/c mice against leishmaniasis. the effects of these fractions on immune...

objective: extracellular deposition of the beta-amyloid (aβ) peptide, which is the main finding in the pathophysiology of alzheimer’s disease (ad), leads to oxidative damage and apoptosis in neurons. melissa officinalis (m. officinalis) is a medicinal plant from the lamiaceae family that has neuroprotective activity. in the present study we have investigated the protective effect of the acidic ...

abstract chromium is among the metals that has numerous applications in various industries due to its specifications. widespread use of this metal in different industries has unfortunately been accompanied by its increased release into environment and this entails numerous environmental hazards. in the first phase of the research that was conducted to evaluate the effect of the leather processi...
