PURPOSE To analyze the contribution of the transverse relaxation parameter (T2), macroscopic field inhomogeneities (B0), and blood volume fraction (BVf) to blood oxygen level-dependent (BOLD)-based magnetic resonance (MR) measurements of blood oxygen saturation (SO2) obtained in a brain tumor model. MATERIALS AND METHODS This study was approved by the local committee for animal care and use. ...

Purpose: To explore the child- and parent-related effects of home-based bimanual training in children with unilateral cerebral palsy.Methods: Case series 14 (2–7 years) who completed goal-oriented task-specific for 3.5 hours/week 12 weeks by a program adopting implicit (n = 5) or explicit 9) motor learning. A therapist remedial educationalist coached parents. Progression on goals (Canadian Occu...

The experiment was conducted at Sher-e-Bangla Agricultural University farm, Dhaka, Bangladesh during the period from March to June 2007 with seven treatments viz; T1: Hand picking of infested fruits of bitter gourd at 7 days interval; T2: Neem seed kernel at 5 gm/l of water at 5 days interval +T1; T3: Spray of shobicron 425EC @ 2ml/l of water at 7 days interval + T1; T4: Micronutrient-Zn @ 6.72...

AIM of study was to present material of open partial horizontal laryngectomies (OPHL) in T1b, T2 and T3 larynx cancer treatment in single tertiary referral institution. MATERIAL AND METHODS Retrospective analysis of operating protocols in patients treated in Poznań ENT University Department between 2000-2012 with glottis (T1b - 185, T2 - 185, T3 - 231) and supraglottis tumors (T1 - 80, T2 - 1...

BACKGROUND AND PURPOSE The T2-weighted gradient-echo (GRE) imaging is currently the gold standard MR imaging sequence for the evaluation of patients with cerebral cavernous malformation (CCM) lesions. We aimed to compare the sensitivity of susceptibility-weighted imaging (SWI) with T2-weighted fast spin-echo (FSE) and GRE imaging in assigning the number of CCM lesions in patients with the famil...

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...
