this study was designed to investigate the role of gabab receptor agents on imipramine-induced antinociception in ligated and non-ligated mice using hot-plate test. the data showed that different doses of morphine (3, 6, and 9 mg/kg) induced a dose-dependent antinociception in ligated and non-ligated mice. however, the opioid response was decreased in ligated animals. intracerebroventricular (i...

in this research, mechanical alloying was used to synthesize ultrafine grained aa2024 and aa2024-b4c powders in an attrition mill under argon atmosphere up to 50 h with the rotational speed of 400 rpm. in order to determine the grain size of the matrix, x-ray diffraction test and williamson–hall method was used. after mechanical alloying, hot pressing and hot extrusion were used for densificati...

In this research the effect of initial microstructure on hot deformation behavior in terms of Ferrite-to-Austenite ratios is studied. Two types of stainless steels C1 and C2 were homogenizing heat-treated and deformed under hot compression examinations at temperatures 900ºC and 1100ºC at strain rate of 0.1s-1. The results showed that the flow stress levels of specimens are strongly r...

the current work was carried out to characterize welding of aisi 310 austenitic stainless steel to inconel 657 nickel-chromium superalloy. the welds were produced using four types of filler materials; the nickel-based corresponding to inconel 82, inconel a, inconel 617 and austenitic stainless steels 310. of the two joints involved, this paper describes the choice of welding consumables for the...

objective: the present study was designed to investigate the analgesic effect of oral and i.p. administration of alcoholic viscum album (v.a) fruit extract as a rich source of alkaloid substances. materials and methods: experimented animals were divided into control and treatment groups. the treatment rats received different doses of the v.a fruit extract, which was prepared from alcoholic sma...

Hot deformation behavior and the microstructural evolution of Inconel 625 superalloy plates are investigated by hot compression tests in a range working temperatures (800–1050 °C) strain rates (0.001–1 s−1). The observation shows that strong <110> texture forms when processing temperature is below 950 °C, whose intensity decreases with increases temperature, it disappears compressing abov...

steel 2205 is one of the most famous duplex stainless steels. the microstructure of this steel composed of ferrite and austenite in similar amount. therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. it is not possible to employ the usual heat treatment. it shows the importance of ...

background and objective: hyperalgesia is one of the marked clinical signs of patients with diabetes mellitus that affects their lifestyle. this study was conducted to assess the anti-nociceptive effect of chronic administration of curcumin in streptozotocin (stz)-diabetic rats using formalin, hot tail immersion, and paw pressure tests. materials and methods: this study was conducted on 40 male...
