Isolation and identification of hyperin and naringenin from guava cultivated in Iraq and evaluation of cytotoxic activity of hyperin
...Show More Authors

The guava plant, Psidium guajava L., serves as proof of the abundant donations of nature, providing a delicious guava fruit; this plant is rich in groups of medicinal and nutritional benefits. Guava belonging to the Myrtaceae family, many previous studies reported many phytochemical constituents in its leaves that have many pharmacological activities and medicinal properties; this study focuses on the isolation, structural elucidation and calculation concentration of flavonoids, assessment of the cytotoxic activityof hyperin from Psidium guajava leaves newly cultivated in Iraq. The isolation process involved the use of thin-layer chromatography (TLC) and preparative high-performance liquid chromatography (PHPLC) and structural elucidation involved NMR (nuclear magnetic resonance spectroscopy) and FTIR (Fourier transform infrared spectrometer) for detailed structural insights into 2 isolated flavonoids. The isolation techniques proved effective in obtaining pure samples of hyperin and naringenin from the ethyl acetate and n.butanol fractions and structural elucidation techniques gives a good explanation for 2 isolated flavonoids. Evaluate cytotoxic activity of hyperin flavonoid against prostate cancer cell line (PC-3), human breast cancer cell line (MCF-7) and normal dermal fibroblast neonatal (HdFn), hyperin flavonoid exhibited a decrease in cell viability (%) with IC50 58.9 ?g /mL against the prostate cancer cell and IC50 90.58 ?g /mL against human breast cancer and noncytotoxic to HDFn, with an IC50 value substantially surpassing concentrations of 100 ?g/mL. These analytical approaches provided a comprehensive understanding of the chemical composition of the isolated flavonoids and interpreted that guava has cytotoxic activity against some cancers, depending on a concentration-dependent mode.

This research is under the title (Construction Grammar in the Kurdish language), which in turn is an attempt to present grammar and Kurdish grammar from the perspective of the constructive of Cognitive Linguistics. The construction as a term in the Kurdish language base was not recent, as it was discussed in other schools in a specific way from the perspective of language schools, but the subject of construction with a perceived background includes specific purposes, which is how to build the linguistic base by being a template accessible to its speakers, and in the cases of speaking it, not to mention how it is perceived and the level it is familiar with by its speakers. The nominal purpose of the Construction is Unification of form-mea

Phytochemical Comparison Study for Evaluating the Hypolipidemic Effect Between Two Iraqi Pepper Spp in the Rats Model.
...Show More Authors

Hypercholesterolemia is a predominant risk factor for atherosclerosis and cardiovascular disease (CVD). The World Health Organization (WHO), ) recommended reducing the intake of cholesterol and saturated fats. On the other hand, limited evidence is available on the benefits of vegetables in the diet to reduce these risk factors, so this research was conducted to compare the hypolipidemic effect between the extracts of two different types of Iraqi peppers, the fruit of the genus Capsicum traditionally known as red pepper extract (RPE), and Piper nigrum as black pepper extract (BPE), respectively, in different parameters and histology of the liver of the experimental animals. The red pepper was extracted by ethyl acetate, while the black pepp

A Spike Neural Controller for Traffic Load Parameter with Priority-Based Rate in Wireless Multimedia Sensor Networks
...Show More Authors

Wireless Multimedia Sensor Networks (WMSNs) are a type of sensor network that contains sensor nodes equipped with cameras, microphones; therefore the WMSNS are able to   produce multimedia data such as video and audio streams, still images, and scalar data from the surrounding environment. Most multimedia applications typically produce huge volumes of data, this leads to congestion. To address this challenge, This paper proposes Modify Spike Neural Network control for Traffic Load Parameter with Exponential Weight of Priority Based Rate Control algorithm (MSNTLP with EWBPRC). The Modify Spike Neural Network controller (MSNC) can calculate the appropriate traffi

Violet Laser Irradiation Effect on The Optical Properties of Cobalt oxide (CoO<sub>2</sub>) Thin Films deposited via Semi-Computerized Spraying System
...Show More Authors
Abstract<p>The existing investigation explains the consequence of irradiation of violet laser on the optic properties of (CoO<sub>2</sub>) films. The film was equipped by the utilization of semi-computerized spray pyrolysis technique (SCSPT), it is the first time that this technique is used in the preparation and irradiation using a laser in this technique. From the XRD analysis, the crystalline existence with trigonal crystal system was when the received films were processed by continuous violet laser (405 nm) with power (1W) for different laser irradiation time using different number of times a laser scan (0, 6, 9, 12, 15 and 18 times) with total irradiation time(0,30,45,60,75,90 min</p> ...

Abstract: The increased interest in developing new photonic devices that can support high data rates, high sensitivity and fast processing capabilities for all optical communications, motivates a pre stage pulse compressor research. The pre-stage research was based on cascading single mode fiber and polarization maintaining fiber to get pulse compression with compression factor of 1.105. The demand for obtaining more précised photonic devices; this work experimentally studied the behavior of Polarization maintaining fiber PMF that is sandwiched between two cascaded singe mode fiber SMF and fiber Bragg gratings FBG. Therefore; the introduced interferometer performed hybrid interference of both Mach-Zehnder

Semi – automated analysis for the Nanoscale determination of Chlorpheniramine maleate drug using sodium nitroprusside by continuous flow feed via homemade NAG-SSP Photometer
...Show More Authors

This study presents a rapid, sensitive, and straightforward approach to measure chlorpheniramine maleate (CPM) by using turbidity CFIA. The method involves CPM reacting with sodium nitroprusside (Nitropress) to produce a pale white precipitate. The NAG-SSP-5S1D analyzer was used to measure turbidity at 0°–180° angle to detect the attenuation of incident light as a result of collision on the surfaces of the precipitate particles. The linear range of CPM measurements was between 0.008 and 11 m.mol/L, with correlation coefficient of 0.9983 and R2% = 99.65. The limit of detection was determined to be 0.0328 µg/sample from the lowest concentration in the calibration curve, and the repeatability of the method (RSD%) was less than 0.4% (n = 6
