Magnetic resonance imaging (MRI) is being used as an outcome criterion in therapeutic trials in multiple sclerosis (MS) on the assumption that it, as a sensitive marker of biologic disease activity, could serve as a surrogate marker of disability. We evaluated the relation between MRI findings and disability in a quantitative follow-up study of 48 MS patients. Median duration of follow-up was 2...

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 ...

Objective: 1. To evaluate different pulse sequence options available for T2 Mapping of human myocardium vis-à-vis accuracy of T2 measurements in phantoms. 2. To propose a practical approach to T2 evaluation that can be used in clinical setting to distinguish tissues with T2 differences 3. To get a range of values for human myocardial T2 values using the most accurate and practical approach. 4. ...

The buffalo milk was used to prepare paneer incorporated with spinach powder which collected from the local market of Latur. chemical composition such had fat 6 percent, solid not 9 percent and protein 3.50 percent. Addition as per treatments. For optimization proper level in heated above 90­ ºC for 5 min then cooled 80 recommended amount weighed added treatments followed by continuous stirring...

Partial sequences of the RNase P RNA gene (rnpB) were obtained from a number of hemoplasmas and other Mycoplasma species. Phylogenetic analysis of these sequences showed that all hemoplasmas were present within a single clade and were most closely related to Mycoplasma fastidiosum, similar to the results found with 16S rRNA gene phylogeny.

A mutant strain deficient in RNase T was isolated and used to study the role of this enzyme in Escherichia coli. Strains lacking as much as 70% of RNase T activity, alone or in combination with the absence of other RNases, display normal growth properties. However, in cca strains, which lack tRNA nucleotidyltransferase, RNase T-deficient derivatives accumulate lower levels of defective tRNA and...

conclusion in breast cancer after nac, the lesion t2 relaxation time was reduced in the responders, and this finding is potentially useful to assess the response to nac. results in 26 cases with nac, the mean lesion t2 relaxation time before nac was 81.34 ± 13.68 ms, compared with 64.50 ± 8.71 ms after nac. significant differences in the lesion t2 relaxation times existed between the pre- and p...

Sensitive profile searches and fold recognition were used to predict the structures of two yeast RNase P/MRP proteins. Rpp1p, which is one of the subunits common to eukaryotes and archaea, is predicted to adopt the seven-stranded TIM-barrel fold found in PHP phosphoesterases. Pop3p, initially thought to be one of the RNase P/MRP subunits unique to yeast, has been assigned the L7Ae/L30e fold. Th...
