background: the involvement of water-soluble carotenoids, crocins, as the main and active components of crocus sativus l. extract in learning and memory processes has been proposed. in the present study, the effect of crocins on sporadic alzheimer's disease induced by intracerebroventricular (icv) streptozocin (stz) in male rats was investigated. methods: male adult wistar rats (n = 90 and...
In the present study, we established dose-response relationships between central administration of 4-hydroxy-2,2,6,6-tetramethylpiperidine 1-oxyl (Tempol, a superoxide dismutase mimetic) and the level of renal sympathetic nerve discharge (SND) and tested the hypothesis that intracerebroventricular (icv) Tempol pretreatment would attenuate centrally mediated changes in SND produced by icv ANG II...
Chronic intracerebroventricular (icv) administration of neuropeptide-Y (NPY; 10 micrograms/day) was performed in normal female rats to investigate its hormonal and metabolic consequences. Intracerebroventricular NPY produced hyperphagia, increased basal insulinemia, as well as liver and adipose tissue lipogenic activity. It also increased basal morning corticosteronemia. When NPY-induced hyperp...
ii) The control valve Manufacturer can only state the Inherent valve characteristics, which refer to the flowrate (F) – valve travel position (m or Z) relationship, when the pressure drop across the control valve (DPV) is constant. Note that the pressure drop across the control valve (DPV) can be almost constant only if the piping system pressure drop (DPS) is concentrated at the control valve ...
This paper presents research on applications of fuzzy logic and higher-order fuzzy logic systems to control filters reducing air pollution [1]. The filters use Selective Catalytic Reduction (SCR) method and, as for now, this process is controlled manually by a human expert. The goal of the research is to control an SCR system responsible for emission of nitrogen oxide (NO) and nitrogen dioxide ...
BACKGROUND Bicuspid aortic valve is frequent and is reported to cause numerous complications, but the clinical outcome of patients diagnosed with normal or mildly dysfunctional valve is undefined. METHODS AND RESULTS In 212 asymptomatic community residents from Olmsted County, Minn (age, 32+/-20 years; 65% male), bicuspid aortic valve was diagnosed between 1980 and 1999 with ejection fraction...
PURPOSE The purpose of the study is to explore effect of 6 weeks treadmill exercise on brain insulin signaling and β-amyloid(Aβ). METHODS The rat model of Alzheimer's disease(AD) used in the present study was induced by the intracerebroventricular(ICV) streptozotocin(STZ). To produce the model of animal with AD, STZ(1.5mg/kg) was injected to a cerebral ventricle of both cerebrums of Sprague-D...
The effects of intracerebroventricular (icv) vasoactive intestinal polypeptide (VIP), secretin, glucagon, and cholecystokinin-octapeptide (CCK-8) on the thermoregulatory and cardiovascular systems were studied in conscious rats. The icv injection of VIP at a dose of 10 micrograms produced hyperthermia with an increase in the positive difference between the interscapular brown adipose tissue (BA...
In Persian traditional medicine is believed that camphor (a crystalline ketone obtained from cinnamomum camphora) is a suppressor of sexual behaviors. This study examined the central effects of camphor on sexual hormones (LH, FSH and testosterone) and GnRH plasma levels in male rat. Male Wistar rats weighing 250-260gr were selected and divided into control (no treatment), sham (ICV injection...
