Staphylococcus aureusis a grave community-acquired and nosocomial pathogen related to elevated levels of morbidity and mortality and produces a high number of toxins and other virulence agents. So, our review focuses on how S. aureusbegins, colonizes, and causes the infection and uponthe main determinants involved. This bacterium toxins included different types like (Alpha, Beta, Gamma, and Delta) Hemolysins, Leukotoxins, Staphylococcal Enterotoxins (SEs), Exfoliate Toxins (ETs) ,Toxic-Shock Syndrome Toxin (TSST)and Toxin-antitoxin (TA) systems.. Studying the determinants of staphylococcal virulence and determining its structure, function, and epidemiology will facilitate the development of strategies to eliminate its resistance to antibiotics, especially in the absence ofan anti-S. aureusvaccine.
金黄色葡萄球菌是一种严重的社区获得性和医院内病原体,与发病率和死亡率升高有关,并产生大量毒素和其他致病因子。因此,我们的综述将重点放在金黄色葡萄球菌如何开始、定殖和引起感染以及所涉及的主要决定因素上。这种细菌的毒素包括不同类型,如(α、β、γ和δ)溶血素、白细胞毒素、葡萄球菌肠毒素(SE)、脱落毒素(ET)、毒性休克综合征毒素(TSST)和毒素-抗毒素(TA)系统。研究金黄色葡萄球菌毒力的决定因素并确定其结构、功能和流行病学将有助于制定消除其抗生素耐药性的策略,尤其是在缺乏抗金黄色葡萄球菌疫苗的情况下。

Samples have been collected from two sources of water: drinking water and well water, for various depths for the Al-Bayaa region in Baghdad using a gamma spectrometer with the Germanium HPGe detector. The results of the analysis show that the average activity concentrations were 1.19±0.5 for 238U, 0.96±0.2 for 232Th, and 10.5±0.5 퐵푞/L for 40K in drinking water samples, and1.77±0.5 for 238U, 1.03±0.2 for 232Th, and 12.6± 0.5퐵푞/퐿for 40K in well water samples, respectively. The results were less than their recommended. The study also calculated the radiation hazards represented by the radium equivalent activity, Gamma index, Hazard Index, Absorbed gamma dose rate, Annual effective dose equivalent, and Lifetime cancer risk. All the radiological parameters in water drinking and well samples were within the range of the global limit; thus the water drinking and well water was Safe and free from radioactive contamination in that area
在巴格达的巴亚地区,使用伽马能谱仪和锗 HPGe 探测器从饮用水和井水这两种水源中采集了不同深度的样本。分析结果表明,在饮用水样本中,238U 的平均放射性浓度为 1.19±0.5,232Th 为 0.96±0.2,40K 为 10.5±0.5퐵푞/L;在井水样本中,238U 为 1.77±0.5,232Th 为 1.03±0.2,40K 为 12.6±0.5퐵푞/퐿。这些结果均低于其建议值。研究还计算了镭当量活度、伽马指数、危害指数、吸收伽马剂量率、年有效剂量当量和终生致癌风险所代表的辐射危害。饮用水和井水样本中的所有放射性参数都在全球限值范围之内;因此,该地区的饮用水和井水是安全的,没有受到放射性污染。

Polyvinyl chloride (PVC) has attracted great attention because of its applications in different fields such as industrial and medical fields. In this work PVC has been reacted with diphenylglyoxime (DPG) in Tetrahydrofuran (THF) to form PVC–DPG polymer, then the synthesized polymer reacted with alcoholic solutions of different metal ions (Fe(II), Co(II), Ni(II), Pd(II), Pt(IV) and Cu(II) to form colored metal ion complexes. All compounds are characterized by Fourier-transform infrared (FTIR), Ultraviolet (UV-Vis) spectroscopies, magnetic susceptibility and conductivity measurements. All complexes were examined with staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative), confirming the biological activity against these bacteria

Image Hiding in an Audio File Using Chaotic Method via Genetic Algorithm 基于遗传算法的混沌音频文件图像隐藏方法
Pub Date : 2023-09-01 DOI: 10.22401/anjs.26.3.06

Information security is one of the most important parts of information technology and communication in the modern world. Information security has gained a lot of attention recently due to the need to transmit information through global communication channels and through the Internet. In this research, the genetic algorithm is used to develop the chaotic maps that are randomly generated by the chaotic system to find the best map by which the locations of image data are inferred to be hidden in the audio. An average image size of 64×64 pixels is used to be hidden in an audio recording of 7 seconds duration at average resolution specifications. The results show that one of the chaotic maps created at the 739 generations is the best in determining image byte hiding locations in the high-frequency band of the audio. The quality measures show the cover audio that includes the hidden image is not much different from the original input one. This confirms the validity of the proposed method and the good selection of hiding locations in accordance with information security concepts.
信息安全是当今世界信息技术和通信的重要组成部分之一。由于需要通过全球通信渠道和互联网传输信息,信息安全最近得到了很多关注。本研究采用遗传算法对混沌系统随机生成的混沌映射进行开发,寻找最佳的混沌映射,从而推断出图像数据的位置隐藏在音频中。在平均分辨率规格下,平均图像大小为64×64像素,用于隐藏在持续时间为7秒的音频记录中。结果表明,在739代生成的混沌映射中,其中一种映射在确定音频高频波段的图像字节隐藏位置方面效果最好。质量测量表明,包含隐藏图像的掩蔽音频与原始输入音频相差不大。这证实了所提出方法的有效性,并且根据信息安全概念选择了良好的隐藏位置。

Many deepfake techniques in the early years are spread to create successful deepfake videos (i.e., Face Swap, Deep Fake, etc.). These methods enable anyone to manipulate faces in videos, which can negatively impact society. One way to reduce this problem is the deepfake detection. It has become such a hot topic and the most crucial task in recent years. This paper proposes a deep learning model to detect and evaluate deepfake video methods using convolutional neural networks. The model is evaluated on the FaceForensics++ video dataset that contains four different deepfake ways (deepfake, face 2 face, face swap, and neuraltexture), and it achieved 0.96 accuracy on the deepfake method, 0.95 accuracy on face 2 face approach, 0.94 precision on face swap method and 0.76 accuracy on neuraltexture method.

Type-2 diabetes mellitus (T2DM) is a disease accompanied by induced oxidative stress (OS) conditions. A reduction in antioxidant activity characterizes the OS conditions. Antioxidants protect cell components from the harmful effects of reactive oxygen species (ROS). The oxidation of the lipid components by ROS has the potential to generate malondialdehyde (MDA). The assessment of MDA (which is a byproduct of lipid peroxidation) may serve as a sign of oxidative damage. This can shed light on the impact of ROS on lipids. This study aims to elucidate the correlation between MDA oxidative stress biomarkers and lipids in individuals diagnosed with type-2 diabetes mellitus. The study comprises two case groups of 30 diabetic patients, 30 obese patients, and 30 healthy patients as the control group. The levels of MDA in the plasma specimens are measured. The serum glucose, serum lipid, and glycated haemoglobin (HbA1c) are evaluated for these groups. The results among patients with and without T2DM are analyzed with regard to age and BMI. The concentration of the MDA is [17.08 ± 1.989 (nmol/ml)] for diabetic patients, [16.08 ± 2.049 (nmol/ml)] for obese patients, and [12.12 ± 1.508 (nmol/ml)] for control patients. A statistically significant difference of p <0.0001 is observed in the elevated levels of MDA among T2DM patients. As compared to healthy control participants, there is no significant difference between T2DM and obese patients. It is concluded that the MDA can be utilized for observing the oxidative stress related to T2DM. The data indicate that utilising MDA could help predict the oxidative environment.
2型糖尿病(T2DM)是一种伴有诱导氧化应激(OS)状况的疾病。抗氧化活性降低是OS条件的特征。抗氧化剂保护细胞成分免受活性氧(ROS)的有害影响。脂质成分被ROS氧化有可能产生丙二醛(MDA)。评估丙二醛(这是脂质过氧化的副产物)可以作为氧化损伤的标志。这可以阐明活性氧对脂质的影响。本研究旨在阐明2型糖尿病患者丙二醛氧化应激生物标志物与血脂的相关性。本研究分为糖尿病患者30例、肥胖患者30例和健康患者30例两组作为对照组。测定血浆标本中丙二醛的水平。评估这些组的血清葡萄糖、血脂和糖化血红蛋白(HbA1c)。分析了T2DM患者和非T2DM患者的年龄和BMI。糖尿病患者MDA浓度为[17.08±1.989 (nmol/ml)],肥胖患者为[16.08±2.049 (nmol/ml)],对照组为[12.12±1.508 (nmol/ml)]。T2DM患者的MDA水平升高,差异有统计学意义p <0.0001。与健康对照组相比,T2DM和肥胖患者之间无显著差异。由此可见,MDA可用于观察T2DM的氧化应激。数据表明,利用MDA可以帮助预测氧化环境。

Pub Date : 2023-09-01 DOI: 10.22401/anjs.26.3.08
Hussein R. Hasan, Fadhel S. Fadhel
The main objective of this paper is to introduce interval two-point fuzzy boundary value problems, in which the fuzziness course when the coefficients of the governing ordinary differential equation and/or the boundary conditions include fuzzy numbers of either triangular or trapezoidal types. Such equations will be solved by introducing the concept of α – level sets, α  [0,1] to treat the fuzzy ordinary differential equation into two nonfuzzy ordinary differential equations, which correspond to the lower and upper solutions of the interval fuzzy solutions. The well-known variational iteration method has been used to solve two-point fuzzy boundary value problems and linear equations have been examined.

Social media and the World Wide Web have led to a worrying rise in spreading false information, which presents a significant worldwide issue. Identifying and preventing false information is crucial in promoting an informed and knowledgeable society. The identification of false information, specifically in the Arabic dialect, presents inherent difficulties due to its diverse characteristics and linguistic intricacies. This study implements AutoKeras, a deep learning-based machine learning framework. Using advanced optimization techniques, the neural network architecture search, hyperparameter adjustments, and model selection can all be automated in AutoKeras. Therefore, it is suitable for our fake news detection task. The methodology employs proficient deep learning algorithms and natural language processing methods to acquire distinct characteristics that enable accurate differentiation between genuine and fake news. The present study uses various sources, including news websites, social media platforms, and blogs, to construct the dataset. The AutoKeras-based approach is superior to multiple state-of-the-art approaches to detecting fabricated news in Arabic, as evidenced by the experimental results. The suggested method outperforms 93.2% accuracy in identifying fake news, demonstrating its superior efficacy. This demonstrates the great promise of the deep learning-based Auto model for detecting false information.
社交媒体和万维网导致虚假信息的传播令人担忧,这是一个重大的全球性问题。识别和防止虚假信息对于促进一个知情和知识渊博的社会至关重要。识别虚假信息,特别是在阿拉伯语方言中,由于其多样化的特征和语言的复杂性,提出了固有的困难。本研究实现了AutoKeras,一个基于深度学习的机器学习框架。使用先进的优化技术,神经网络架构搜索,超参数调整和模型选择都可以在AutoKeras中自动化。因此,它很适合我们的假新闻检测任务。该方法采用熟练的深度学习算法和自然语言处理方法来获取独特的特征,从而能够准确区分真假新闻。本研究使用各种来源,包括新闻网站、社交媒体平台和博客,来构建数据集。实验结果证明,基于autokeras的方法优于多种最先进的方法来检测阿拉伯语中的虚假新闻。该方法识别假新闻的准确率超过93.2%,显示了其优越的有效性。这证明了基于深度学习的Auto模型在检测虚假信息方面的巨大潜力。

The plant Gossypium Hirsutum genotypes were grown in Qwshtapa district, Grdmala village, which is 30 kilometres from the centre of Erbil, Iraq. The cotton genotypes grown there included Coker 310, Lachata (Iraqi genotypes), Cafko, Dunn 1047, Montana, Stone Ville (USA genotypes), Bakhtegon, Khdorda, and Vanamin (Iranian genotypes). The anatomical investigation demonstrates distinct petioles, midribs, laminas, and margin outline shapes among the genotypes. They contain secretory tissues, cluster crystals, and tannins. While some genotypes lack the trichomes, others have; these genotypes are multicellular glandular and unicellular branching or unbranched nonglandula.
这种棉花基因型在距伊拉克埃尔比勒中心30公里的Grdmala村的Qwshtapa区种植。在那里种植的棉花基因型包括Coker 310、Lachata(伊拉克基因型)、Cafko、Dunn 1047、Montana、Stone Ville(美国基因型)、Bakhtegon、Khdorda和Vanamin(伊朗基因型)。解剖研究显示不同基因型的叶柄、中脉、薄板和边缘轮廓形状不同。它们含有分泌组织、簇状晶体和单宁。虽然一些基因型缺乏毛状体,但其他基因型有;这些基因型是多细胞腺型和单细胞分支型或无分支的非腺型。
