Kidney stone disease is a highly significant clinical issue that poses a serious threat to both global health and the economy. For the sustainability of good health and well-being of kidney stone patients, this study aimed to elucidate the role of the enzyme glyoxylate reductase and hydroxypyruvate reductase (GRHPR) in the formation of the kidney stones and their development. There are many different types of kidney stones, but calcium oxalate kidney stones are the most prevalent in Iraq. In this study, 50 Iraqi patients with calcium oxalate stones (25 males and 25 females) were compared to 30 healthy control groups (17 males and 13 females). The biochemical tests for kidney function, such as serum urea, creatinine, and uric acid, were d

The research is demonstrating the use of an X-ray diffraction pattern obtained experimentally from barium oxide powder. The X-ray diffraction pattern of the barium oxide nanoparticle sample was analyzed through the program to obtain the mean intensity width values and use these values to extract the particle size for all diffraction pattern lines using the Scherrer method. The nanoparticle size was calculated for each barium oxide line. Then the dislocation density was calculated through two mathematical equations, one of which depended on the particle size and the other depended on the integral breadth, a comparison was made between the results of the two dislocation densities and the particle size, where it was found
... Show MoreMesoporous silica was developed to transport metoprolol tartrate (MPT). The data obtained from the kinetic experiments of adsorption of 15 ppm of MPT drug at 293 K was fitted in the pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. The results show that the adsorption process obeys the pseudo-first-order equation and the rate-controlling step, not just the intraparticle diffusion step. The MPT drug load onto mesoporous silica was 15.13 mg/g. The release profile shows that the MPT drug was about 55% released after 40 min when released in water, while in phosphate-buffered saline (PBS) media, the release reached 90% after 60 min at body temperature (37°C). Three kinetic release versions, including first-order, K
... Show MoreThis paper presents two important contributions to the field of numerical analysis for third-order ordinary differential equations (ODEs). First, a new class of direct implicit Runge-Kutta (RK) processes, called RKTDIO, is introduced as solutions to third-order ODEs. Secondly, it develops the ERKTDIO method, which is an embedded pairwise diagonal implicit RK method. The study begins by introducing the theory of relevant-colored trees and B-series as fundamental concepts. By utilizing the order constraints, two RKTDIO methods are derived: a fifth-order method with three stages and a sixth-order method with four stages. In addition, an embedded method called ERKTDIO6(5) is derived, which has orders six and five. The derivation of the embed
