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...

INTRODUCTION The goals of this study were (i) to compare the prevalence of focal knee abnormalities, the mean cartilage T2 relaxation time, and the spatial distribution of cartilage magnetic resonance (MR) T2 relaxation times between subjects with and without risk factors for Osteoarthritis (OA), (ii) to determine the relationship between MR cartilage T2 parameters, age and cartilage morphology...

Let n≥1, K>0, and let X=(X1,X2,…,Xn) be a random vector in Rn with independent K–subgaussian components. We show that for every 1–Lipschitz convex function f (the Lipschitzness respect to the Euclidean metric), ∀t>0, max(P{f(X)−Medf(X)≥t},P{f(X)−Medf(X)≤−t})≤exp(−ct2 K2log(2+K2n t2)), where c>0 is universal constant. The estimates are optimal sense n≥C˜ t>0 there exist product probability distr...

Aiming at the problems of high missed-pickup rate and crushed caused by different types peanut harvester pickup drums, tracking a field comparative experiment from 2020 to 2021, rate, quality distribution, distribution rule pods with degrees crushing observed in two varieties drums were studied. Three kinds pod-pickup set up: axial flow (T1), tangential (T2) tangential–axial (T3), they installe...

The main objective of this study was evaluation of integrated management and mixing saline/fresh water on soil salinity distribution. For this purpose, a field was selected and 32 plots were made in it with a 6 m×2.5 m size. A split plot experiment was employed with two sunflower varieties (Alstar and Hisan33), four irrigation schemes (CIS) and four replications. Irrigation schemes being ...

زمینه:طی سال های اخیر، بروز و گسترش مقاومت داروئی در مایکوباکتریوم توبرکلوزیس، باکتری مولد سل، این بیماری را در اولویت های سازمان بهداشت جهانی هم ردیف بیماری هایی مانند ایدز و هپاتیت قرار داده است. بررسی دقیق ژنوتیپ سویه های کلینیکی مقاوم و حساس برای غلبه بر مقاومت دارویی ایجاد شده ضرورت دارد. از میان سیستم های متعدد ترمیم تنها تعداد محدودی ژن کد کننده آنزیم های ترمیم dnaدر مایکوباکتریوم توبرکل...

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...

Purpose: To investigate the robustness of four fitting methods for bi-component effective spin-spin T2 (T2*) relaxation time analysis of human patellar tendon. Methods: A three-dimensional (3D) cone ultrashort echo-time (UTE) sequence was performed on the knees of ten healthy volunteers at 3.0T. Four fitting methods incorporating either Gaussian or Rician noise distribution were used for voxel-...

Longitudinal and transverse relaxation times are used to characterise the pore system of a natural Kaldenkirchen sandy loam. Here we present new results obtained by relaxometric imaging (MEMS) and two-dimensional T1-T2 correlation relaxometry, and compare these with available T1relaxation time distributions of water obtained by the analysis of fast field cycling relaxometry (FFC) data. The soil...
