background: microrna-155 (mir-155) is upregulated during t cell activation, but the exact mechanisms by which it influences cd4+ t cell activation remain unclear. objective: to examine whether the b and t lymphocyte attenuator (btla) is a target of mir-155 during naïve cd4+ t cell activation. methods: firefly luciferase reporter plasmids pezx-mt01-wild-type-btla and pezx-mt01-mutant-btla were c...

background: faba bean (vicia faba) is a rich source of protein and carbohydrates that is used as a vegetable ingredient in diet of livestock, poultry and fish, in many countries. objectives: this study was conducted to assess the effects of different levels of faba bean on the serum lipid levels and liver function of farmed beluga sturgeon (huso huso). methods: 144 juvenile beluga (82.38 ± 0.83...

isolation of some potent anti-tumor compounds from medicinal plants has motivated researchers to screen different parts of plant for their anti-tumor effects. it has been reported that several species of conifers posses’ cytotoxic activities on some tumor cell lines. here branchlets and berries of juniperus foetidissima and j. sabina were collected, dried and ethanol extracts of them obtained u...

in order to evaluate of abscisic acid, paclobutrazol and uniconazole hormones effects on the egyptian broomrape (orobanche aegyptiaca. pers) control and growth indexes of tomato (lycopersicon esculentum mill.), a glasshouse experiment was conducted in crd design with four replications. treatments consisted of abscisic acid in 4 levels (1, 3, 5 and 7 mm), paclobutrazol in 2 levels (0.1 and 0.01 ...

introduction: various bone palliative therapeutic agents have been developed and widely used for bone metastasis such as 153sm-edtmp. in this study, production, quality control and biodistribution studies of a newly developed therapeutic compound have been presented followed by imaging studies in wild-type rodents. methods: 153sm-tthmp was prepared starting from 153sm-smcl3, prepared by neutro...

background: in order to diagnose the site of thrombi, radiolabeled streptokinase can be prepared. the radiolabeled compound can be used in imaging of thrombi in many cardiovascular diseases. materials and methods: streptokinase was successively labeled with [67ga]-gallium chloride using cyclic dtpa-dianhydride. the conjugation with dtpa was optimized for concentration, time and temperature foll...

introduction: due to the cell labeling potentials of various metal-maltol complexes, the idea of developing a possible cell labeling imaging agent using single photon emission computed chromatography (spect) with[111in]-maltolate complex has been investigated. methods: [111in] labeled 3-hydroxy-2-methyl-4h-pyran-4-onate ([111in]-maltolate) was prepared using freshly prepared [111in]incl3 and ...

this experiment was carried out to investigate the effect of bulb harvesting time and indole butyric acid as well as changes of endogenous growth regulators, indole acetic acid and abscisic acid during scale propagation of lilium ledebourii (baker) boiss. treatments consisted of bulb harvesting time (0, 50, 100 and 150 days after flowering) in the natural habitat of damash, and iba concentratio...
