Arterial pressure (AP), heart rate (HR), cardiac sympathetic tonus (ST), and parasympathetic tonus (PT) were determined in spontaneously hypertensive rats (SHR, 8 male and 8 female) and Wistar-Kyoto normotensive rats (WKY, 8 male and 12 female) before and after acute exercise. Before exercise, hypertensive rats (regardless of gender) had an increased ST (+15 beats/min), increased resting HR (+1...
این پایان نامه در جهت بهبود عملیات شیرین سازی گاز ترش طبیعی و بررسی امکان سنجی جایگزین حلال sulfinol-d به جای حلال mdea مورد استفاده در واحد های شیرین سازی پارس جنوبی فاز (9و10) مورد مطالعه قرار گرفت که این حلال متشکل از حلال فیزیکی و آبی آمینی را که به استفاده جذب فیزیکی و شیمیایی است. بررسی پارامتر های مختلف دما – غلظت و دبی حلال ورودی به برج جذب مورد ارزیابی قرار گرفت. برای تحلیل بهتر نتایج ...
In this study the optimal amount of enriching Artemia franciscana with a synbiotic combination of Pediococcus acidilactici and fructooligosaccharide (FOS( was investigated. The experiment was conducted in a completely randomized design in ten treatments: multi-level probiotics P. acidilactici (1×109, 1×108 and 1× 107 CFU per L) and mul...
PURPOSE Pulse wave velocity (PWV) is at least partially controlled by vascular tone. Vascular tone and underlying physiological processes such as sympathetic activity, plasma catecholamin, and cortisol levels have been shown to follow diurnal variations. MATERIALS AND METHODS Carotid-to-radial PWV was non-invasively assessed by applanation tonometry in 21 young (26.5+/-2.3 years) healthy men ...
fifteen broiler chickens (cobb 400) of 42 days of age weighing 1.8 to 2.0 kg were equally divided into 3 groups, each consisting of 5 birds. hepatopathy was induced by oral administration of paracetamol while nephropathy was induced by intravenous administration of uranyl nitrate. kinetic study was investigated in healthy, hepatopathic and nephropathic birds following single oral administration...
MM virus (mouse-brain stock) replicated to a limited extent in L cells without cytopathic effects; the average yield was less than 1 plaque-forming unit/cell. Passage in BHK-21 cells resulted in MM virus [MM(BHK)] which replicated to high titers (200 to 300 plaque-forming units/cell) in L cells with complete cytopathic effects. Appearance of mature MM(BHK) virus in L-cell cultures begins 4 hr a...
To determine the effects of diabetic ketoacidosis on the brain, we studied nine consecutive patients between the ages of 6 and 17 years by performing cranial CT on three occasions: on admission, before treatment; 6-8 hr after beginning treatment; and 7 days after admission. Both the pretreatment scans and those at 6-8 hr showed significantly reduced size of the lateral and third ventricles in c...
In this study, we evaluated the impact of secondary genetic lesions in acute myeloid leukemia (AML) with inv(16)(p13.1q22) or t(16;16)(p13.1;q22); CBFB-MYH11. We studied 176 patients, all enrolled on prospective treatment trials, for secondary chromosomal aberrations and mutations in N-/KRAS, KIT, FLT3, and JAK2 (V617F) genes. Most frequent chromosomal aberrations were trisomy 22 (18%) and tris...
In unequal alternating monocular exposure (unequal AME), each eye receives normal patterned visual input but on alternate days and for unequal periods. It has been shown previously that this imbalance in stimulation produces a deficit in the nasal visual field of the less experienced eye (LEE). The effect of subsequent binocular exposure on these visual deficits has now been examined. No eviden...
