the main objective of the present study was investigation on influences of different brackish water sources on freshwater prawn larval quality and developmental indices. for this study, along a larval period, four brackish water treatments with 12 ppt salinity including diluted marine water, brackish water from marine crystalline salt, brackish water with compounds of new formula and brackish w...
Arsenic (As) is a human carcinogen. Our prior work showed that chronic (>18 weeks) low level (500 nM) arsenite (As3+) exposure induced malignant transformation in a rat liver epithelial cell line (TRL 1215). In these cells, metallothionein (MT) is hyper-expressible, a trait often linked to metal tolerance. Thus, this study examined whether the adverse effects of arsenicals and other metals were...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
objective(s): there are many reports about the role of rostral ventromedial medulla (rvm) in modulating stress-induced analgesia (sia). in the previous study we demonstrated that temporal inactivation of rvm by lidocaine potentiated stress-induced analgesia. in this study, we investigated the effect of permanent lesion of the rvm on sia by using formalin test as a model of acute inflammatory pa...
acute toxicity (96h-lc50) of potassium permanganate (pm) was determined for caspian kutum rutilus frisii kutum at two size classes (1 and 3 g). static renewal method was used. fish were exposed to different concentrations of pm and mortality was recorded thereafter, until 96 h. exposed fish showed behavioral stress indicators. 96h-lc50 was calculated to be 3.204 (3.147-3.260) mg/l for small fis...
GABAergic drugs can change analgesic effect of morphine. Wide dynamic range (WDR) neurons play an important role in pain transmission and may change behaviors in morphine tolerance. In this study WDR neuron behaviors in morphine tolerant rats and rats treated with GABA agonists, were recorded to elucidate the effect of morphine and GABA agonists on WDR behavioral changes. Rats were divided to 4...

Increasing in water ammonia is one of the major problems in aquaculture. Nitrogen-containing materials are producing in different ways, including oxidation of nitrogen-containing organic matters such as proteins, manure decomposition and ammonia excretion by fish. The increase in these compounds in water recirculation systems and aquaria has always been considered as a stress-causing factor. On...
objective(s): intracerebroventricular injection of orexin-a (hypocretin-1) antagonist has been shown to inhibit stress-induced analgesia. however the locations of central sites that may mediate these effects have not been totally demonstrated. this study was performed to investigate the role of rostral ventromedial medulla (rvm) orexin receptor 1 in stress-induced analgesia (sia). materials and...
