In the context of the shell model, electromagnetic transitions were used to analyze the nuclear structure of a mirror nucleus with the same mass number, A = 13. The shell model investigation was performed by calculating the root mean square (rms) for the proton, neutron, matter and charge radii, occupancies, the excitation energies, as well as electromagnetic moments, using the elements of a body density matrix of the PSDMOD two-body effective interactions carried out in the psdpn-shell model space. The present results adopted the harmonic oscillator's single particle eigen functions and Hartree-Fock approximation. In addition, the effect of core polarization was added using the effective charge and effective g factors to calculate electromagnetic moments. To acquire a fair analysis of the information, the core polarization has to be present. The outcomes were compared with experimental data
在壳模型的背景下，利用电磁跃迁分析了具有相同质量数（A = 13）的镜像核的核结构。壳模型研究是通过计算质子、中子、物质和电荷半径、占位、激发能量以及电磁矩的均方根（rms），使用在 psdpn 壳模型空间进行的 PSDMOD 两体有效相互作用的体密度矩阵元素来实现的。本结果采用了谐振子单粒子特征函数和哈特里-福克近似。此外，利用有效电荷和有效 g 因子计算电磁矩时还加入了核极化效应。为了获得公正的信息分析，必须存在核心极化。结果与实验数据进行了比较

In this paper, the problem of oscillating solutions for an impulsive hematopoiesis model with positive and negative coefficients is investigated. There are several evolutionary processes, which frequently encounter dramatic shifts at specific times and are sensitive to short-term perturbations. As a result, we construct several oscillation criteria that are either brand-new or enhance many of recent findings in the literature. We also give illustrations of how impulsiveness affects the oscillating solutions of the hematopoiesis model.

Heme oxygenase-1(HO-1) is an enzyme that catalyzes and breaks down heme molecules into biliverdin, free iron, bilirubin, and carbon monoxide. This study aims to investigate the levels and role of (HO-1) in obese patients against oxidative stress and its relationship to obesity. The study included 139 samples: (84 obese and 55 non-obese persons). Both study groups were divided into four groups based on their Body Mass Index (BMI). Blood sample was collected from obese persons and control groups (men and women) at AL-Yarmouk Hospital and the National Diabetes Research Center at the period between December-2022 until June-2023. Some biochemical parameters were measured for all studied groups, which include: Determining of HO-1 levels in serum by using the ELISA-technique, lipid profile and fasting serum glucose (FSG) assessed enzymatic. BMI levels were found to be increased significantly in obesity class II group, obesity-class I group, and overweight group compared with normal weight groups. Also, the results showed that waist hip ratio (WHR (was significantly increased (p≤ 0.05) in groups obesity class II, obesity class I, and overweight group compared with normal weight group. Also, the results showed that the HO-1 levels were higher in obese-class I patients and obese-class II group compared with normal-weight and overweight groups. The statistical analysis displayed that, the level of HO-1 is associated negatively with BMI in normal weight group (G1), while positively with the obesity-class II, obesity-class I, and overweight groups. We conclude from this study that the body's first line of defense against oxidative stress attack is HO-1. This cell-protective enzyme reduces oxidative stress and is vital for controlling lipogenesis, which is crucial for the development of metabolic diseases and its complications.
血红素加氧酶-1（HO-1）是一种催化和分解血红素分子为胆绿素、游离铁、胆红素和一氧化碳的酶。本研究旨在调查肥胖患者体内（HO-1）的水平和作用，以对抗氧化应激及其与肥胖的关系。研究包括 139 个样本：(84名肥胖者和55名非肥胖者）。两组研究人员根据体重指数（BMI）分为四组。在 2022 年 12 月至 2023 年 6 月期间，在 AL-Yarmouk 医院和国家糖尿病研究中心采集了肥胖者和对照组（男性和女性）的血样。对所有研究组的一些生化参数进行了测量，其中包括使用 ELISA 技术测定血清中的 HO-1 水平、血脂概况和酶法评估的空腹血清葡萄糖 (FSG)。结果发现，与正常体重组相比，肥胖 II 级组、肥胖 I 级组和超重组的 BMI 水平明显升高。结果还显示，与正常体重组相比，肥胖 II 级组、肥胖 I 级组和超重组的腰臀比（WHR）明显增加（P≤ 0.05）。结果还显示，与正常体重组和超重组相比，肥胖 I 级患者和肥胖 II 级组中的 HO-1 水平更高。统计分析显示，正常体重组（G1）的 HO-1 水平与体重指数呈负相关，而与肥胖 II 级、肥胖 I 级和超重组呈正相关。我们从这项研究中得出结论，人体抵御氧化应激攻击的第一道防线是 HO-1。这种细胞保护性酶可减少氧化应激，对控制脂肪生成至关重要，而脂肪生成对代谢性疾病及其并发症的发生至关重要。

This research deals with the properties of polyethylene (PE) using lactams with metallic nano-oxide compounds extracted from (clove) plants, specifically the flower buds of the clove tree as stabilizers and reducing agents, where the nano-oxide stabilizes and covers the natural polymer. The study aims to show that the nano-oxide performs the best bonding of the prepared composites, due to the increased surface area, and thus can bind to the prepared polymer and ability of electronic stability is due to a large number of bonds, which allow the electronic charge to be distributed and then dispersed outside the surface of the polymer, which improves the properties of the polymer and makes it an environmentally friendly material with the easiest casting technique. So that it does not harm human health and other living organisms. In this study zinc oxide nanoparticles were prepared from natural plant sources high product to be used as a catalyst for the preparation of industrially important monomers, and a lactam polymer was added in the presence of zinc oxide extracted from plant (cloves). Poly lactam is a synthetic polymer that degrades when consumed by humans. Oxide nanoparticles, monomers, and polymers were characterized using spectroscopy methods. FTIR and TGA analysis indicated that using X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy the resulting polymer is a high molecular weight homogeneous material grafted with high-quality nanoscales.

Fascioliasis is a zoonotic disease, caused by the parasites Fasciola (F.) hepatica and F. gigantica, which poses a great threat to the ruminants in addition to humans in many countries, including Iraq. Hence, the study of this parasite and its deleterious impacts on host, morphologically, histopathologically, epidemiologically, and molecularly, is so important. Hence, the current study was designed to investigate this fluke of livestock in Erbil and Halabja slaughterhouses from August to October 2022. To meet the prerequisites of the study, 33 flukes were collected from the sheep and cattle at study sites. The samples were transported to the Zoology Research Laboratory, Salahaddin University-Erbil, Iraq. Some of them were used for morphological identification, and others were preserved in 96% ethanol and stored at -20°C. Subsequently, DNA was extracted. Conversely, pieces of the infested liver were fixed in 99% ethanol and 10% formalin before histopathologic examination. The parasite species were identified using traditional Polymerase Chain Reaction (PCR), and sequencing methods. Macroscopically, hepatomegaly was the main finding of the infestation. Among livestock, cattle exhibited the highest rate of morbidity, followed by goats and sheep. The amplified DNA region was 98–99%, matched to F. hepatica and F. gigantica sequences. It was also established that 28S rDNA sequencing combined with morphologic characteristics of Fasciola species can be applied as a salient indicator in the identification of flukes. The current study is reckoned as a comprehensive investigation regarding fascioliasis, because it covered the parasite epidemiology, morphology, and molecular identification, despite of histopathologic examination.

This study involves the synthesis of CuCo2O4 spinel-type nanocomposite. This material was synthesized using the co-precipitation method and characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-rays Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Atomic Force Microscopy (AFM). The activity of the synthesized materials was investigated by following removing basic fuchsine (BF) dye from its aqueous solution by adsorption. Different adsorption parameters were conducted involving the dose of adsorbent surface, time of adsorption, pH of the medium, and temperature. The optimum removal efficiency was around 97 % at contact time 5 minutes, 0.005g of dose the surface adsorbent, pH = 8 and 50 mg. L-1 concentration of dye. Thermodynamic parameters for the adsorption of this dye over the prepared materials were also conducted such as free energy (∆G) negative. While enthalpy (∆H) positive which indicates the adsorption was spontaneous and endothermic, also entropy (∆S) was positive shows the affinity of the adsorbent towards the adsorbate.

This study aims to determine the effect of chronic administration of amphetamine-type stimulants at varying doses on inflammation and oxidative stress in Wistar rats. They were given methylphenidate and divided into 4 treatment groups. Furthermore, simple random grouping was carried out to divide the samples into 5 groups, each consisting of 9 rats. These groups included rats given only distilled water as the controls, as well as those given methylphenidate at doses of 10 mg/kg BW, 20 mg/kg BW, and 40 mg/kg BW for 4 weeks as the experimental groups. Statistical analysis was then performed using GraphPad Prism to compare the effects of oxidative stress, systemic inflammation, BDNF, and spatial memory of the Wistar rats. Chronic administration of stimulants led to a significant decrease in glutathione peroxidase levels as well as an increase in the release of IL-6 and tumor necrosis factor-α compared to the control group. Based on the results, the pathways involved in cognitive impairment, which were related to the use of amphetamine-type stimulants played a role in addressing the detrimental effect of substance abuse and their comorbidities

Based on the results, the pathways involved in cognitive impairment, which were related to the use of amphetamine-type stimulants played a role in addressing the detrimental effect of substance abuse and their comorbidities","PeriodicalId":8687,"journal":{"name":"Baghdad Science Journal","volume":"752 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139160624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
This paper is devoted to investigating the Hopf bifurcation of a three-dimensional quadratic jerk system. The stability of the singular points, the appearance of the Hopf bifurcation and the limit cycles of the system are studied. Additionally, the Liapunov quantities technique is used to study the cyclicity of the system and find how many limit cycles can be bifurcated from the Hopf points. Due to the computational load required for computing Liapunov quantities, some parameters are fixed. Currently, the analysis shows that three limit cycles can be bifurcated from the Hopf points. The results presented in this study are verified using MAPLE program.
本文致力于研究三维二次方抽动系统的霍普夫分岔。研究了奇异点的稳定性、霍普夫分岔的出现以及系统的极限循环。此外，还使用了李雅普诺夫量技术来研究系统的循环性，并找出从霍普夫分岔点可以分岔出多少个极限循环。由于计算 Liapunov 量所需的计算负荷，一些参数是固定的。目前，分析表明，从霍普夫点可以分叉出三个极限循环。 本研究提出的结果已通过 MAPLE 程序验证。
