background: the alteration of th1 and th2 cytokine levels is the subject of controversy in pleural effusions caused by malignancy, a situation that favors a th2 immune response. objective: to examine the different levels of il-4 and il-10 (th2 cytokines), and il-2 and interferon-γ (ifn-γ) (th1 cytokines) in malignant and non-malignant pleural effusions. method: the cytokine levels in pleural fl...

basil (ocimum basilicum l.) belongs to the lamiaceae family as a medicinal plant used in traditional medicine in iran. the purpose of this test is to evaluate the effect of nano fe-chelate under salinity levels on the plant physiology and morphology characteristics. in this experiment  investigated the effect of nano fe-chelate and salinity stress on growth parameters, photosynthetic leaves rat...

this study aimed at determining the evapotranspiration and crop coefficient (kc) of sugar beet during the plant growth using drainage lysimeter by using water balance and experimental methods for three years in shahrekord. after sugar beet planting and out of lysimeter, evapotranspiration was measured weekly and monthly by measuring the factors of the water- balance equation. results showed tha...

two cu(ii) complexes, [cu(l1)2](no3)2 (1) and [cu(l2)2] (no3)2(2), which l1 and l2 schiff base ligands are 2-(thiophene-2-yl) -1h-imidazo [4,5-f] [1,10] phenanthroline and 2-(furane-2-yl)-1h-imidazo[4,5-f] [1,10] phenenthroline, respectively, were synthesized and characterized by physico - chemical and spectroscopic methods. corresponded cuo nanoparticles were prepared by calcination of the obt...

melissa (melissa offcinalis l.), a member of a lamiaceae family, is a medical plant. the main most important pharmacological properties can be soothin, strengthening nerve, carminative and memory booster. the presence of heavy metals is one of important environmental stresses that can reduce growth and production of types of reactive oxygen. in the present study, the effect of copper sulfate (c...

with regard to the positive effects of training in individuals with multiple sclerosis (ms) and gender differences in the prevalence and pattern of multiple sclerosis, the aim of this study was to determine the effect of eight weeks of selected training on some cytokines (tnf?, ifn?, il-10, hs-crp) in male and female ms patients. for this purpose, 35 male and female patients with ms (edss

the application of organic sorbents for removing heavy metal from water, replacing expensive sorbents, is particularly appropriate for developing countries. to investigate the efficiency of some organic sorbents in removing of cd2+ from aqueous solution, an experiment was conducted with three organic sorbents (sunflower stalks, apple and grapevine pruning residues) and 11 initial concentration ...

4-chloro-3,5-dioxaphosphacyclohepta[2,1-;3,4-']dinaphthalene (binol-pcl) was found to be an efficient, bulky and selective reagent for the transformation of symmetric and asymmetric benzoins to the corresponding benziles at 0 °c to room temperature under nitrogen atmosphere in good yield.

coccinellids play a major role in aphid control. hippodamia variegata goeze is an aphidophagous predator of worldwide distribution that could be found in different parts of iran. one of the criteria for evaluating the efficiency of a predator is its response to change in prey population density (functional response). the functional responses of males and females of hippodamia variegata were stu...
