the purpose of this study was to assess exposure to hand-arm vibration in tiller users, forty users of tiller in northeastern provinces of iran were examined to measure hand-arm vibration parameters such as root mean square acceleration (rms), total equivalent acceleration, vibration dose value (vdv) and crest factor in three directions (x, y, and z) and various operating modes for comparing th...

The research study was designed to compare the safety and efficacy of the regimen of 5-flurouracil with cisplatin of investigational arm with the reference regimen of gemcitabine with cisplatin for the treatment of gallbladder cancer. A total of 60 patients were enrolled in the study. Out of 30 patients enrolled in arm-A (Gemcitabine with Cisplatin) and 30 patients enrolled in arm-B (5-Fluroura...

kaposiform hemangioendothelioma is an aggressive endothelial-derived spindle cell neoplasm that occurs nearly exclusively during childhood and teenage years. the lesion grows rapidly and is often associated with kasabach-merritt syndrome. in this study a 24 days old male neonate who presented with an ill-defined deeply situated violaceous mass on his left arm is described. he had also anemia an...

Cocrystallization of 7,7?,8,8?-tetracyanoquinodimethane radical anion (TCNQ–•) and 3-methylpyridinium-1,2,3,5-dithiadiazolyl cation (3-MepyDTDA+•) afforded isostructural acetonitrile (MeCN) or propionitrile (EtCN) solvates containing cofacial ? dimers homologous components. Loss lattice solvent from the diamagnetic above 366 K affords a high-temperature paramagnetic phase discrete TCNQ–• weakly...

Kinetic resolution of a series fluorinated styrene oxide derivatives was studied using halohydrin dehalogenase. A mutant HheC-W249P catalysed nucleophilic ring-opening with azide and cyanide ions excellent enantioselectivity (E-values up to >200), which gives access various enantiopure ?-substituted alcohols epoxides. It found that the enzyme tolerates substrates in concentrations over 50 mM. H...

introduction: effective perception of fear signals is crucial for organism survival. when threated, the organism indicates defensive behaviors. methods: elevated plus–maze has high efficiency for measurement of fear behavior and is widly used for fear behavior determination. increase in two parameters percent of openarm entries (%oae) and percent of time spent in the open-arm (%oat) in the elev...
