The Turkmen horse is one of the oldest and purest breeds in the world. There is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. Pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. There were 26 stallions and 16 mares. The left ventricular isovolumetric contrac...
Due to the need for new fumigants to control insects that attack food commodities, the toxicity of acetone was determined on some species of stored pest insects in Urmia University in the year 2000. In empty space tests, the LC50 values of acetone for Oryzaephilus surinamensis (L.), Callosobruchus maculatus (F.), Tribolium confusum (Duv.) and Sitophilus granarius (L.) were 15.40, 15.51, 17.55 a...
OBJECTIVES The purpose of this study was to evaluate to which degree investment of acquisition time in more encoding directions leads to better image quality (IQ) and what influence the number of encoding directions and the choice of b-values have on renal diffusion tensor imaging (DTI) parameters. MATERIAL AND METHODS Eight healthy volunteers (32.3 y ± 5.1 y) consented to an examination in a...
این پژوهش به منظور شناخت تنوع ژنتیکی 12 جمعیت متعلق به 4 گونه گیاه دارویی salvia (مریم گلی) با استفاده از بررسی کروموزم های سلول های مریستمی نوک ریشه بذور با روش استو-فریک-هماتوکسیلین صورت گرفت. عدد کروموزومی جمعیت های هرگونه ثابت و گونه salvia officinalis 14=x2=n2، گونه های، s. macrosiphon mirzayanii s. دارای 20=x2=n2 و گونه salvia sclarea دارای 20= x2=n2 بودند. به منظور تعیین تقارن کاریوتیپی،...
این پژوهش به منظور شناخت تنوع ژنتیکی 8 جمعیت متعلق به 4 گونه گیاه دارویی salvia (مریم گلی) با استفاده از بررسی کروموزم های سلول های مریستمی نوک ریشه بذور با روش استو-فریک-هماتوکسیلین صورت گرفت. عدد کروموزومی جمعیت های هر گونه ثابت و گونه salvia hydrangea دارای 14=x2=n2، گونه s. virgata دارای 16=x2=n2، گونه s. lachnoclyx دارای 22=x2=n2 و گونه s. verticillata دارای 32=x4=n2 بودند. به منظور تعیین ...
Background & Aim: Nalidixic acid is a quinolone antibiotic with excellent in vitro and in vivo activity against salmonella. It is often the first choice for treating drug resistance salmonella infections. Nalidixic acid resistance can often lead to resistance to fluoroquinolones such as ciprofloxacin. In this survey the extent of salmonella infections, the salmonella strains involved, antib...
Aim. To compare the diagnostic performance of diffusion weighted imaging (DWI) using b-values of 1000 s/mm(2) and 2000 s/mm(2) at 3 Tesla (T) for the evaluation of clinically significant prostate cancer. Matherials and Methods. Seventy-eight prostate cancer patients underwent a 3T MRI scan followed by radical prostatectomy. DWI was performed using b-values of 0, 1000, and 2000 s/mm(2) and quali...
To evaluate controlled pressure coronary artery perfusion fixation of hearts as a means of obtaining meaningful cardiac measurements at autopsy, left ventricular (LV) autopsy measurements were correlated with in vivo end-diastolic (D) and end-systolic (S) angiographic (angio) values from biplane cineangiograms in the same patients. Mitral (MV) and aortic valve (AV) circumferences, LV equatorial...
Although the efficacy of transcatheter arterial chemoembolization (TACE) has been recommended as first-line therapy for nonsurgical patients with hepatocellular carcinoma (HCC), it is difficult to accurately predict the efficacy of TACE. Therefore, this study evaluated the efficacy of TACE for HCC using magnetic resonance (MR) diffusion-weighted imaging (DWI). A total of 84 HCC patients who rec...
