In this paper, we demonstrate a rapid simultaneous measurement of diffusion constant D, T1 and T2 relaxation times in just two scans. Theoretical standard deviations of D, T1 T2 for a wide range of T1 and T2 were predicted for given sequences with a random experimental error of 3%. By carefully selecting of sequence parameters for samples with different relaxation times, the error propagators i...

common infections encountered in children. Most bacterial infections are caused by Streptococcus pyogenes (1). In addition, resurgence of severe forms of disease caused by S. pyogenes has been detected in various parts of the world (2, 3). Although all S. pyogenes strains remain exquisitely sensitive to penicillin, erythromycin has been the drug of choice for individuals who cannot take penicil...

Effective food waste management is key to a sustainable future. We herein aimed at assessing the composition and amount of generated in Chamchuri (CU) Terrace condominium (floors 18–22) Bangkok (Thailand), producing soil amendment material from this same examining effect bioplastic bags on composting. The 29.01 kg general per day. (6.26 kg/day) was classified into “available” “unavailable” wast...

We investigated whether magnetic resonance imaging (MRI) might be applicable to evaluation of the ovarian activity of microminipigs. Firstly, using three mature microminipigs, we confirmed ovarian position and morphology by laparotomy or laparoscopy, and then acquired MRI images in various patterns to determine the most suitable condition for the acquisition. Next, using four microminipigs, we ...

Systems for multivariate on-line surveillance (e.g. outbreak detection), are investigated. Optimal systems for statistical surveillance are based on likelihood ratios. Three systems are compared; based on each marginal density, based on the joint density and based on the Hotelling’s T2. The effect of dependency between the monitored processes is investigated, and the effect of correlation betwe...

Putative changes of metabolite T2 relaxation times were investigated before and after a 20-min period of global ischemia in rat brain in vivo (n = 10) using localized proton MRS at different echo times (2.35 T). Neither absolute T2 relaxation times (TE = 20-270 ms) nor time courses of T2-weighted metabolite signals (TE = 135 ms) revealed statistically significant changes during the occlusion or...

Background: Magnetic resonance imaging (MRI) contrast agents have an important role to differentiate healthy and diseased tissues. Access and design new contrast agents for the optimal use of MRI are necessary. This study aims to evaluate iron oxide–4A nanocomposite ability to act as a magnetic resonance imaging contrast agent.Materials and Methods: Iron oxide–4A nanocomposite (F4A) was syn...
