H, P NMR, Raman and FTIR spectroscopies for investigating phosphoric acid dissociation to understand phosphate ion kinetics in body fluids.

The study investigates the formation and transportation of ionic charge carriers in phosphoric acid-water system. This investigation encompasses an analysis of H and P NMR chemical shifts, self-diffusion coefficients, spin-lattice relaxation rates, spin-spin relaxation rates, activation energies, dissociation constants, electrical conductivity, and Raman shifts, along with FTIR spectra across various water concentrations. Significantly, the maxima observed in these curves at around 0.

Preparation and Characterization of Capsaicin Encapsulated Polymeric Micelles and Studies of Synergism with Nicotinic Acids as Potential Anticancer Nanomedicines.

Background/objective/methods: Capsaicin micelles were prepared by the direct dissolution using the amphiphilic copolymer Pluronic P123 and advanced for substantially novel submicro-nanocytotoxicity.

Results: Superior cytotoxicity of capsaicin loaded nanomicelles vs. both the raw capsaicin and reference cisplatin in pancreatic PANC1, breast MCF7, colorectal resistant CACO2, skin A375, lung A549 and prostate PC3 cancer cell lines were delineated.

Assessment of Patient Radiation Dose during Conventional Diagnostic X-ray Examinations in Three Public Hospitals in Northern Jordan using TLDs.

This study aims to measure entrance surface doses during routine chest and abdomen x-ray examinations of adult and child patients. Radiation dose measurements were performed using thermoluminescent dosimeters TLD-100s in three major public hospitals in northern Jordan on a total of 100 patients. Wide variations in entrance surface doses were observed within and between hospitals, which might be attributed to significant variations of the selected exposure parameters.

Fat-water separation in dynamic objects using an UNFOLD-like temporal processing.

Purpose: To separate fat and water signals in dynamic imaging. Because important features may be embedded in fat, and because fat may take part in disease processes, separating fat and water signals may be of great importance in a number of clinical applications. This work aims to achieve such separation at nearly no loss in temporal resolution compared to usual, nonseparated acquisitions.

On the correlation between T(2) and tissue diffusion coefficients in exercised muscle: quantitative measurements at 3T within the tibialis anterior.

Purpose: To assess the transverse relaxation time T(2) and diffusion coefficient D before and following exercise in the tibialis anterior muscle and determine whether T(2) and D values were correlated.

Methods: Measurements of T(2) and D were performed at 3 T within axial slices through the calf muscles of six healthy volunteers at 95 s intervals before and for 10-12 min after a dorsiflexion exercise to exhaustion.

Results: The mean +/- standard deviation (SD) of T(2) and D before exercise were 32 +/- 1.
