it has been reported that different species of euphorbia (euphorbiaceae) have antitumor activity. some reports also show that these plants have potential cytotoxic effect against different cell lines. in a program to screen the cytotoxicity of iranian native plants, euphorbia macroclada boiss. was collected, identified, and the cytotoxic activity of dichloromethane, ethylacetate, methanol extra...

Considering the fact that only pores can transport water, in homogeneous control volume are conceptualized as a three-dimensional orthogonal network of line elements, which is contrast to continuum hypothesis traditional numerical approaches. The related flow velocity, hydraulic conductivity and continuity equation equivalent model formulated based on principle balance. Subsequently, unified fo...

1. A preparation of completely haemolysed erythrocytes from the blood ofdomestic fowls, which actively incorporates [Ox-14C]glycine into haem, is described. 2. The effects of time and of glycine concentration on the rate of synthesis were studied. 3. Stimulation of the synthesis up to sixfold was obtained with some preparations of boiled yeast extract. 2:4-Dinitrophenol inhibited the synthesis ...

In the present investigation, co-invasion of Lernaea parasite is reported in some fish species, collected from the Kor River Basin (Dorudzan Reservoir and Kor River), Southwest of Iran in 2010 and 2011.  Lernaea cyprinacea parasites were isolated from the external surface of eye, lips, gills, nostrils, fins, operculum and body of Alburnus mossulensis, Capoeta aculeata, Capoeta saadii (all nativ...

A few of the presented soil behavior models are capable of predicting the triggering and post liquefaction and also shear band mechanism through the soil media. The assessment of earth-dam body behavior as a soil structure made of cohesive soil in core and non-cohesive soil as the core supports, including water interaction at upstream through earthquake upon a multi-line constitutive equations ...

Maternal antibodies are transferred from hens to the chicks via the egg. To gain insight into maternal antibody transfer and endogenous production of antibodies in broiler chicks, total IgY, IgA, IgM, as well as anti-Newcastle disease virus (NDV) and anti-infectious bronchitis (IBV) antibody levels were examined in the dams' plasma, egg yolks, egg whites, and chicks' plasma on d 3, 7, 14, and 2...
