Background Transfusion-induced iron overload leads to many complications in patients with β-thalassemia major. This study aimed to compare the level of iron stored in the liver and heart measured by MRI T2 * with ferritin levels in these patients. Materials and Methods This study was done on 52 patients with β-thalassemia major aged 7 to 29 years. Serum ferritin level was checked and heart and ...

MRI has recently been applied to study the retina in vivo. Measurements of relaxation time constants (T1, T2, and T2*) and the apparent diffusion coefficient (ADC) of the retina would be useful to systemically optimize structural, physiological, and functional MRI contrasts. MRI studies were performed on 12 anesthetized and paralyzed rats. High-resolution T1, T2, T2* and ADC of the rat eyes wer...

This paper discusses the decidability of determinacy and subsumption for tree transducers. For two tree transducers T1 and T2, T1 determines T2 if the output of T2 is identified by the output of T1, that is, there is a partial function f such that [[T2]] = f ◦ [[T1]] where [[T1]] and [[T2]] are tree transformation relations induced by T1 and T2, respectively. Also, T1 subsumes T2 if T1 determin...

A field experiment was conducted to study the effect of iron fertilization on growth, yield and quality groundnut (Arachis hypogaea L.) during kharif, 2016 (June September at instructional farm, Swami Keshwanand Rajasthan Agricultural University, Bikaner, Rajasthan, India. Twelve treatments viz. T1: control (water spray); T2: FeSO4 basal @ 25 kg ha-1; T3: Foliar spray citric acid 0.1% 45 75 day...

BACKGROUND Myocardial T1, T2 and T2* imaging techniques become increasingly used in clinical practice. While normal values for T1, T2 and T2* times are well established for 1.5 Tesla (T) cardiovascular magnetic resonance (CMR), data for 3T remain scarce. Therefore we sought to determine normal reference values relative to gender and age and day to day reproducibility for native T1, T2, T2* mapp...

BACKGROUND Alveolar type II (T2) cells synthesise matrix proteins such as type IV collagen and fibronectin. In contrast, a fetal rat T2 cell line has been shown to synthesise type I and III collagen as well as type IV collagen. To study regulation of collagen production in T2 cells, neonatal T2 cells immortalised by adenoviral 12SE1A gene transfer were used. It was previously reported that this...

Background Osteoporosis affects 1 in 4 women and 1 in 8 men over 50 years and its burden on healthcare resources is enormous. Despite the risk factors and biological processes leading to bone loss have been well studied, little is known about the mechanisms that initiate bone loss in the first place. Osteocytes, marrow adipocytes and haematopoetic cell lines share a common precursor in the marr...

The effect of ascorbic acid (AA) and butylated hydroxyanisole (BHA) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for AA and BHA) in diet containing 1 ppm total aflatoxin (AF: 76.45% AFB1, 10.52% AFB2, 9.89% AFG1 and 3.14% AFG2). A total of 300 day-old broiler chicks were divided into ten treatment groups (T1=control; T2...
