OBJECTIVE Hippocampal sclerosis (HS), the most common cause of refractory temporal lobe epilepsy, is associated with hippocampal volume loss and increased T2 signal. These can be identified on quantitative imaging with hippocampal volumetry and T2 relaxometry. Although hippocampal segmentation for volumetry has been automated, T2 relaxometry currently involves subjective and time-consuming manu...
OBJECTIVE An experiment was conducted to determine the nutrient intake, digestibility, microbial protein synthesis, haemato-biochemical attributes, immune response and growth performance of Gaddi kids fed with oat fodder based basal diet supplemented with either tea seed or tea seed saponin (TSS) extract. METHODS Eighteen male kids, 7.03±0.16 months of age and 19.72±0.64 kg body weight, were ...
Ziel: Ziel der vorliegenden Studie war es, zu untersuchen mit welcher diagnostischen Genauigkeit das T2-Mapping die Visualisierung eines Myokardödems beim akuten Myokardinfarkt (AMI) erlaubt und diese diagnostische Genauigkeit mit der des gegenwärtigen Standards für die myokardiale Ödembildgebung (T2-gewichtete, dark-blood präparierte TSE-Sequenz) zu vergleichen. Material und Methoden: 29 Patie...
Background: Conventional T2W imaging alone has a poor sensitivity for prostate cancer detection. This study therefore evaluated combined T2-W and diffusion weighted (DW)-MRI vs. T2-W MRI alone for identifying tumour in patients with prostate cancer. Material and Methods: 54 consecutive patients with prostate cancer (46 Stage 1 and 2, 8 stage 3) and sextant biopsies within the previous 3 months ...
Parsnip fermented juice (PFJ) and hawthorn extract (HE) were identified as natural nitrite antioxidant sources for pork mince. This study aimed to determine the effects of varying levels HE added a constant concentration PFJ on lipids stability, heme pigment conversion degree, residual content, spoilage bacteria growth, during refrigeration, compared with combined effect synthetic sodium ascorb...
DVB-T is the most widely used standard for digital television broadcast. With its introduction in 1997, it more than 70 countries. Almost all of these countries adopted new terrestrial broadcasting – DVB-T2. DVB-T2 best technology broadcasting, which offers better signal robustness, flexibility and 50% efficiency, compared with other broadcast systems. This paper focuses on ways to deliver MPEG...
Abstract Background Endometriosis is a common gynecologic disorder characterized by the implantation of endometrial tissue ectopically outside cavity. It affects about 10% females at childbearing period and estimated to be present up 20–50% in women complaining infertility. While laparoscopy considered mainstay for diagnosis, magnetic resonance imaging (MRI) recognized as useful tool definitive...
CONTEXT While gray matter T2 hypointensity in multiple sclerosis (MS) has been associated with physical disability and clinical course, previous studies have relied on visual magnetic resonance imaging (MRI) assessments. OBJECTIVE To quantitatively determine if T2 hypointensity is associated with conventional MRI and clinical findings in MS. DESIGN Case-control study. SETTING University-a...
Soil tillage management for various crops in different regions needs use available indices and information about condition, manual manner, defects and preferences of various tillage methods. Therefore, this experiment was conducted in summer 2003 on clay soil containing wheat residual in Shawoor agricultural research center, situated in northern Ahwaz. Experiment was conducted as a Randomized C...
