PURPOSE The interest in measurements of magnetic resonance imaging relaxation times, T1, T2, T2*, with intention to characterize healthy and diseased lungs has increased recently. Animal studies play an important role in this context providing models for understanding and linking the measured relaxation time changes to the underlying physiology or disease. The aim of this work was to study how ...
BACKGROUND The specific advantage of administering systemic antibiotics during initial, non-surgical therapy or in the context of periodontal surgery is unclear. This study assesses the differential outcomes of periodontal therapy supplemented with amoxicillin-metronidazole during either the non-surgical or the surgical treatment phase. METHODS This is a single-center, randomized placebo-cont...
objectives to investigate the correlation between t2* values of different regions of interest (rois) in myocardium with the means of semi quantitatively estimating the myocardiac iron content in the thalassemia major patients. in the same setting we tried to design a model to predict t2* value of interventricular septum (septum) based on t2* values of other convenient rois in myocardium. method...
Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...
BACKGROUND Studying T1- and T2-mapping for discrimination of acute from chronic myocardial infarction (AMI, CMI). METHODS Eight patients with AMI underwent CMR at 3 T acutely and after >3 months. Imaging techniques included: T2-weighted imaging, late enhancement (LGE), T2-mapping, native and post-contrast T1-mapping. Myocardial T2- and T1-relaxation times were determined for every voxel. Abno...
Feeding fish is one of the most important factors in aquatic nutrition. Regarding the importance of nutrition in aquaculture, many studies have been done; However, few studies have been conducted on the effect of different feeding rates on reproductive activity of fish. This experiment was conducted to determine the effect of feeding rates on reproductive performance of the swordtail (Xiphophor...
conclusions herbal tea of fenugreek seed in comparison to the control group improves the signs of breast milk sufficiency. results before the intervention there was no significant difference between weight, height, head circumference, the number of wet diapers and frequency of defecation between the two groups (p > 0.05), yet the number of breast feeding times of the control group was more than...
