Synthesis and Characterization of Nanoparticles Extracted from <i>Catharanthus roseus</i> Plant
...Show More Authors

The Catharanthus roseus plant was extracted and converted to nanoparticles in this work. The Soxhlet method extracted alkaloid compounds from the plant Catharanthus roseus and converted them to the nanoscale. Chitosan polymer was used as a linking material and converted to Chitosan nanoparticles using Sodium TriPolyPhosphate (STPP). The extracted alkaloids were linked with Chitosan nanoparticles CSNPs by maleic anhydride to get the final product (CSNPs- Linker- alkaloids). The synthesized (CSNPs- Linker- alkaloids) was characterized using SEM spectroscopy UV–Vis., Zeta Potential, and HPLC High-Performance Liquid Chromatography. Scanning electron microscope (SEM) analysis shows that the Chitosan nanoparticles (CSNPs) have small dimensions with regular spherical and nanotube shapes of a diameter range of (49 - 70) nm. The final product (CSNPs- Linker- alkaloids) has two shapes (spherical particles and tubes) in nano dimensions and is close to each other compared to normal Chitosan. The absorption peaks for Chitosan (CS), Chitosan nanoparticles (CSNPs), Chitosan nanoparticles (CSNPs), and maleic anhydride revealed that converting Chitosan to Chitosan nanoparticles and mixing it with the plant extract, led to an increase in the absorption value and wavelength range. Also, the appearance of two peaks at 222 nm and 402 nm nano instead of the peak of Chitosan at 289.9 nm. Zeta Potential results of CSNPs- Linker- alkaloids showed that the extract of the nano-alkaloids bound to chitosan nanoparticles carries a positive charge of 54.4 mV. This surface charge is essential in maintaining the colloidal solution's stability in its natural form without changing. High-Performance Liquid Chromatography (HPLC) was used to estimate qualitative and quantitative plants extracted from Catharanthus roseus. Quantitative HPLC results show that Catharanthus roseus contains a good and acceptable concentration of Vinblastine, Vincristine, Vinorelbine, Vincamine, and Vintafolide (66.75, 242.91, 0.7, 83.77, 42.34) ppm respectively. The qualitative results show a good match for the influential groups of pure standard vincristine and alcoholic extract and dry powder of the Catharanthus roseus plant. The successful synthesis of nanoparticles from the Catharanthus roseus plant can be used in biosensors and biomedical applications.

Study the incidence of Candida infection in Diabetic patients submitted to the Balad Town Hospital in Salah –Eldeen, Province
...Show More Authors

This study was done at Al-Balad City Hospital on 60 diabetic patients (25 male and 35 female). The study included Fasting Blood Sugar and fungal diagnosis (systemic and superficial fungus). The results showed that the high concentration of blood sugar belonged to the group > 70 years among the diabetic patients with high significant differences in comparison with other groups P<0.001 . The result showed that percentage of female systemic fungus infection was higher than male systemic fungus infection ( female 63% and male 24%) and vice versa about superficial fungus infection (female 37% and male 76%) . Data showed that the percentage of nail fungus infection among female diabetic patients was higher than the percentage of male diabetic p

The Impact of Osteoporosis on Teeth Decay in relation to Salivary Vitamin D among Menopause in Baghdad city, Iraq
...Show More Authors

 

Background: Osteoporosis is a systemic skeletal disorder that has an impact on general health, dental health and salivary composition. The mineralization of teeth happens simultaneously with that of the skeleton, but if mineral metabolism is disrupted, tooth failures will resemble those that affect bone tissue. Vitamin D plays a key role in bone and tooth mineralization.

Objective: to evaluate the impact of osteoporosis on teeth decay in relation to salivary vitamin D among menopause in Baghdad city.

Subjects and Methods: This study was cross sectional study. The study group consists of

The Ability of AhR Ligands to Attenuate Delayed Type Hypersensitivity Reaction Is Associated With Alterations in the Gut Microbiota
...Show More Authors

Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that regulates T cell function. The aim of this study was to investigate the effects of AhR ligands, 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD), and 6-Formylindolo[3,2-b]carbazole (FICZ), on gut-associated microbiota and T cell responses during delayed-type hypersensitivity (DTH) reaction induced by methylated bovine serum albumin (mBSA) in a mouse model. Mice with DTH showed significant changes in gut microbiota including an increased abundance of Bacteroidetes and decreased Firmicutes at the phylum level. Also, there was a decrease in Clostridium cluster XIV and IV, which promo

Efficient Approach for Solving (2+1) D- Differential Equations
...Show More Authors

     In this article, a new efficient approach is presented to solve a type of partial differential equations, such (2+1)-dimensional differential equations non-linear, and nonhomogeneous. The procedure of the new approach is suggested to solve important types of differential equations and get accurate analytic solutions i.e., exact solutions. The effectiveness of the suggested approach based on its properties compared with other approaches has been used to solve this type of differential equations such as the Adomain decomposition method, homotopy perturbation method, homotopy analysis method, and variation iteration method. The advantage of the present method has been illustrated by some examples.

Ferritin is a key organizer of protected deregulation, particularly below risky hyperferritinemia, by straight immune-suppressive and pro-inflammatory things. , We conclude that there is a significant association between levels of ferritin and the harshness of COVID-19.

...Show More Authors

 

          In this work, the modified Lyapunov-Schmidt reduction is used to find a nonlinear Ritz approximation of Fredholm functional defined by the nonhomogeneous Camassa-Holm equation and Benjamin-Bona-Mahony. We introduced the modified Lyapunov-Schmidt reduction for nonhomogeneous problems when the dimension of the null space is equal to two.  The nonlinear Ritz approximation for the nonhomogeneous Camassa-Holm equation has been found as a function of codimension twenty-four.
