this paper presents the effect of high environmental heat on behavior of the male charles foster rats. eighty rats were divided into three groups, subjected to (i) acute heat stress (ii) chronic heat stress and (iii) handling control group. animals were exposed to the hot environment in a biological oxygen demand incubator at 38 ± 1ºc (relative humidity 45-50%) for four hours of continuous sing...

echium amoenum (boraginaceae), a very popular medicinal plant in iran traditional medicine, is used as a tonic, tranquillizer, diaphoretic, cough and sore throat remedy, and antipneumonia. preliminary phytochemical studies of the plant showed that it contains saponins, flavonoids, unsaturated terpenoids and sterols. in this study, an aqueous extract from petals of this plant was used 125 mg/kg ...

introduction: this study was designed to investigate the effects of music in wistar rats after sub-chronic treatment of simvastatin. the rats were orally administered with either simvastatin or saline (controls). after 4 weeks of drug treatment, the rats were selected for behavioral studies. the rats were exposed to music 24 hours before behavioral tests (mozart’s piano sonata, kv361, largo). r...

introduction: dracocephalum polychaetum bornum is exclusively found in a limited geographical area in the kerman province it is used by the local people for treatment of abdominal pain, meteorism and musculoskeletal pain. no study has been performed on the effects of d. polychaetum bornum, so the aim of this work was to assess the role of the extract and essential oil of this plant on pain and ...

concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...

introduction: in this study, we investigated the role of n-methyl-d-aspartate (nmda) receptors in the ventral hippocampus (vh) and their possible interactions with gabaa system on anxiety-like behaviors. methods: we used an elevated-plus maze test (epm) to assess anxiety-like behaviors and locomotor activity in male wistar rats. results: the results showed that intra-vh infusions of different d...

anxiety symptoms have been reported to be present in many patients with diabetes mellitus. however, little is known about the effects of hyperglycemia in critical periods of the central nervous system development. we assessed locomotive, exploratory, and anxiety behaviors in adult rats that remained from infantile repeated hyperglycemia by the open field and elevated plus maze tests. our findin...

background: ventilator-associated pneumonia (vap) is the most common nosocomial (hospital acquired) infection among patients undergoing mechanical ventilation. it increases mortality rate, duration of mechanical intubated ventilation, and hospitalization in the intensive care units (icus). this review study aims to determine the proper gradient of a hospital bed in preventing vap in patients ho...

OBJECTIVES To investigate associations between daily concentrations of air pollution and myocardial infarction (MI), ST-elevation MI (STEMI) and non-ST-elevation MI (NSTEMI). METHODS Modelled daily ground-level gaseous, total and speciated particulate pollutant concentrations and ground-level daily mean temperature, all at 5 km×5 km horizontal resolution, were linked to 202 550 STEMI and 322 ...
