abstract mineral weathering is a major source of most essential nutrients including potassium. it is well known that potassium plays an important role in improving the quality of agricultural products and micaceous minerals, as the major source of potassium, are abundant in iranian soils. no information is available on the role of micaceous minerals in supplying k to barley as the second major ...
introduction: legionnair's disease bacterium is a gram negative, facultative intracellular bacilli which parasitize human alveolar macropages as well as some species of free living amobae. this study was achieved in order to compare the cell wall composition in intracellular bacteria. whole cell and outer membrane proteins and the bacterial lipopolysacharide (lps) were analyzec on sds page syst...
Under paddy field conditions, biological sulfur oxidation occurs in the oxidized surface soil layer and rhizosphere, in which oxygen leaks from the aerenchyma system of rice plants. In the present study, we examined community shifts in sulfur-oxidizing bacteria associated with the oxidized surface soil layer and rice roots under different sulfur fertilization conditions based on the 16S ribosom...
Background and purpose: Bleomycin as an anticancer drug causes side effects on normal tissues. The aim of this study was to investigate the effect of methanolic extract of Cichorium intybus seed (CI) on antiproliferative activity of bleomycin on human non-malignant skin and ovarian cancer cells. Materials and methods: Human non-malignant fibroblast cells (HFFF2) and ovarian cancer cells (SKOV-...
To investigate the possibility of horizontal gene transfer between agricultural microorganisms and soil microorganisms in the environment, Bacillus subtilis KB producing iturin and the PGPR recombinant strain Pseudomonas fluorescens MX1 were used as model microorganisms. The soil samples of cucumber or tomato plants cultivated in pots and the greenhouse for a six month period were investigated ...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
Extracellular population responses are largely preferred for the study of long-term potentiation (LTP). The effect of Mg2+-free medium on changes in activity and plasticity of Schaffer collateral-CA1 pyramidal cell synapses was examined. Hippcampal slices from cysteamine-treated (200 mg/kg, s.c.) and saline-injected (1 ml/kg, s.c.) albino rats were perfused with ACSF. Population spikes (PS) wer...
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
Introduction: Colon cancer has spread to developed countries. Probiotic bacteria can play an important role in reducing cancer and treating colon cancer. The aim of this study was to determine the effect of adjacent bovine Lactobacillus rhamnose culture on the expression of casp3 and bax genes in cancer cell. Materials & Methods: In this experimental study after bacterial culture, supernatan...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
