abstractparkinson’s disease (pd) is a neuropathological and debilitating disorder involving the degeneration of mesencephalic dopaminergic neurons. neuroprotective effect of hesperetin has already been reported, therefore, this study examined whether the administration of this flavonoid would attenuate behavioral abnormalities in an experimental model of pd in rat. for this purpose, unilateral ...

the extensive use of pesticides in agriculture is compromising soil and water quality. one major concern is protecting water resources from contamination. the main objective of this research was measuring 2,4- d in a silty clay soil and simulating temporal transportation of this herbicide in soil using a leachp model, in a corn root zone field. 2,4- d was applied at 3.5 kg a.i./ha, followed by ...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

treatment of bone metastases comprises over 10% of the workload of a radiation-oncology center. bone metastases produce severe pain and immobility, necessitate narcotic use, and reduce the quality of life. a good palliative treatment must be complete, free from side effects and fast; thus we decided to evaluate strontium-89 (89sr) effectivity for palliation of breast and prostate cancer bone me...

indandione 1 was brominated to yield 2-bromoindandione 2 which on further reacted with substituted thiocarbamides, carbamides, 2-aminothiophenols, 2-aminophenol and triazoles to furnished 3-substituted aniline-2-thia-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 3, 3-substituted aniline-2-oxa-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 4, 2-thia-5-aza-9-oxo-3,4-(3’-substitut...

regional analysis is one of the important methods for estimating the low flow in ungagged regions. investigation of the relations between effective factors of hydrological drought is the most important strategy to contrast and reduction of drought losses. in this study to analyze of low flow, the daily discharge data from 20 gauging stations with 25 years period (1988-2012) in the kashafroud ba...

the aim of this study was to determine the formulation of silver carp fish cracker and checking qualitative changes of cracker in the four time intervals (0, 30, 60 and 90 days), during storage at room temperature. treatments consisted of dried cracker (drying time 2 hours), cracker were fried (drying time 1 hour) and the final treatment was drought cracker that fried at the end of each period....

background: human t-lymphotropic virus (htlv), a retrovirus, is the causative agent of adult t-lymphocytic leukemia (atl) and tropical spastic paraparesia (tsp). htlv-1 is transmitted mainly through blood transfusion. sabzevar is an endemic region for htlv infection; hence it is essential to detect the prevalence of htlv1/2 infection in the blood donors of this city. materials and methods: in t...

in this study, removal of acid blue 62 from aqueous solution by mesoporous silicate mcm-41 modified by aminopropyltriethoxysilane (aptes) composite was studied. properties of synthesized composite were analyzed and confirmed by sem, edx and ftir. results show that langmuir adsorption isotherm has the best compatibility with the results of experiments. kinetic analysis using pseudo-first-order m...

abstract background: rhabdomyosarcoma is the most common soft tissue sarcoma among children which has two major subtypes: embryonal rhabdomyosarcoma (erms) and alveolar rhabdomyosarcoma (arms). distinction between these subtypes is mandatory to choose proper treatment and to determine prognosis. histopathologic study is the main method, but nowadays molecular studies like pcr are also used. the...
