In recent years, there has been a growing emphasis on nanomaterials, particularly in the realm of medical applications. Zinc oxide nanoparticles are widely recognized as a significant class of oxides of metals due to their inherent structural stability, little toxic effects, and ability to maintain cellular integrity. One of the most important medicinal uses of zinc oxide is medication administration. Twenty-four male albinos’ rats were randomly separated into four groups. Control group, diabetic group, diabetic group treated with insulin, and diabetic group treated with ZnO NPs loaded with insulin. The rats were given medication for 28 days. Diabetes mellitus was induced in the rats with blood sugar levels more than 250 mg/dL by administering alloxan intraperitoneally at a dose of 120 mg/kg. The nanoparticles' physicochemical properties were investigated using a variety of analytical techniques, including UV-Vis spectral analysis, X-ray diffraction (XRD), and Field Emission Scanning Electron Microscopy (FE-SEM). The data revealed significant increases in glucose, cholesterol, triglyceride and total oxidative stress (TOS) as well as a notable decrease in body weight and catalase levels, in the diabetic control group compared to the healthy control group (P< 0.05). Compared to control groups, ZnO NPs loaded with insulin lower total cholesterol, triglycerides and TOS on the other hand increase body weight and catalase levels. The results of our study indicate that the use of photo-synthesized ZnO-NPs in combination with insulin showed noteworthy antidiabetic benefits when compared to the control groups.

Parkinson's disease (PD) is a neurodegenerative illness marked by progressive damage of dopaminergic neurons in the substantia nigra. Synuclein-α protein plays a key role in this term by aggregating in clumps of Lewy bodies causing PD. Despite unclear etiology of PD, growing indications show that PD pathogenesis is associated with gene expression dysregulation. Transcription factors (TFs) are the key players in regulating gene expression. In this study, we employed a bioinformatics tool to predict TF binding to Synuclein-α (SNCA)gene utilizing DNA sequences, epigenetic modifications, TF binding motifs, and creating machine learning algorithms. PROMO database was utilized to identify candidate TFs. Here we found TFs that act as regulators of neuronal function and dopaminergic signaling pathways, including members of the Forkhead box family, and nuclear factor-kappa B family members such as c-Jun, and STATs family. These findings provide a better understanding of the molecular mechanisms underlying PD disease and determine potential therapeutic targets.

Numerous organic compounds have been investigated for their potential to reduce corrosion under various circumstances. This study investigated the effects of di-dodecyl amine, an organic chemical, on carbon steel metal corrosion at different temperatures while HCl acid was present. The examination was carried out using accepted methods for polarization, weight loss, and corrosion process testing. The obtained findings demonstrated that the corrosion rate reduces with increasing inhibitor concentration, leading to increased inhibition efficiency. Furthermore, as shown in the weight loss technique, the corrosion rate lowers with increasing surface coverage with organic inhibitor at 313 °C. In the anodic and cathodic polarization methods, as well as in the inhibition efficiency, it is observed to see the cathodic and anodic curves through which the occurrence of the potential and corrosion current is known. The current and corrosion potential decreases with increasing inhibitor concentration. The amines and methyl motiveless in this inhibitor's composition give it their efficacy since they may coat the metal surface and stop corrosion

This study includes the manufacture of two sets of composite materials consisting of polymethyl methacrylate reinforced with natural fibers. The first (R) group included eight layers of cotton with one layer of hair in the middle, and the second (O) group included six layers of cotton with three layers of burlap in the middle. The thermal conductivity of the two groups was checked using a Lee disc to identify the thermal conductivity (K), of group R 0.0771 w/m.c, and of group O 0.0754 w/m.c. These values are considered good as the material has good thermal insulation due to its low thermal conductivity values and is therefore suitable for use in prosthetic limbs as it can preserve the body temperature from external influences.

A green-synthesis method for silver nanoparticles (Ag NPs) is a scientific breakthrough. Using sunflower plant extracts, this approach uses metallic and botanical synergy. Naturally occurring and renewable extracts reduce, chelate, stabilize, bind, and precipitate. The Ag nanoparticles' X-ray diffraction (XRD) crystal structure was cubic. Average nanoparticle crystallite size was 31.18 nm. Energy-dispersive X-ray spectroscopy (EDX) detected silver. Field Emission Scanning Electron Microscope (FESEM) examination revealed that the particles were Ag (silver) and spherical, averaging 31.23nm. Diffuse Reflectance Spectroscopy also indicated a 2.7 eV optical gap. Using many characterization methods, nanostructured silver was synthesized during this procedure. Biological efficacy assays can evaluate hierarchically porous silver's antibacterial properties.

银纳米粒子（Ag NPs）的绿色合成方法是一项科学突破。这种方法使用向日葵植物提取物，利用金属和植物的协同作用。天然可再生的提取物具有还原、螯合、稳定、结合和沉淀作用。银纳米粒子的 X 射线衍射（XRD）晶体结构为立方体。纳米颗粒的平均结晶尺寸为 31.18 纳米。能量色散 X 射线光谱（EDX）检测到了银。场发射扫描电子显微镜（FESEM）检查显示，颗粒为银，呈球形，平均粒径为 31.23 纳米。漫反射光谱也显示出 2.7 eV 的光隙。利用多种表征方法，在此过程中合成了纳米结构银。生物药效试验可评估分层多孔银的抗菌特性。在过去五年中，针对金黄色葡萄球菌、铜绿假单胞菌、变异链球菌、大肠杆菌、白色念珠菌、青霉属和曲霉属的抗菌策略至关重要。数据表明，这些结构是具有吸引力的抗菌选择。大多数银氧化物是金黄色葡萄球菌、铜绿假单胞菌、变异链球菌和大肠杆菌的天然细菌替代物。还能对抗各种真菌：免疫力低下的宿主的免疫系统会受到白色念珠菌、青霉和曲霉等酵母菌的威胁。这使人们对该研究在抗菌和其他应用方面的功效产生怀疑。

This study investigates the use of agricultural byproducts of plants (Phragmites australis) as low-cost adsorbents for the removal of Cu2+ and Mn2+ from their aqueous solutions through the production of (AC). The results showed that the adsorption equilibrium time for both ions was 30 minutes. The results obtained showed that pH=5, pH=6 for Cu2+ and Mn2+ respectively were optimum to adsorption for these ions. The study showed that the weight (0.5 g) of the adsorbent was ideal to achieve the best adsorption and the ability of the adsorbents to adsorb metal ions was as follows: Cu(II) > Mn(II).

In this research, we focus on the synthesis of titanium oxide (TiO2) nanoparticles using the Nd:Utilization of YAG laser pulse ablation technique in liquid environments, with pulse energies from 100 to 500 millijoules. The process employs a Nd:YAG laser operating at a frequency of 6 Hz and a wavelength of 1064 nm. (The TiO2 nanoparticles synthesized in this study could be used in different high-temperature environments, as they are characterized by favorable physical, chemical, and mechanical properties). The synthesized product was further treated by calcination for four hours at temperatures higher than 600°C which promoted crystalline structure in the lattice. Comprehensive analyses were carried out to determine the nanoparticles' features. Optical features were studied through UV-visible spectroscopy to examine the absorption spectrum and band gap. The detailed examination of the crystal and surface structures was done using X-ray diffraction and field emission scanning electron microscopy (FE-SEM), in order to obtain insight into the structural integrity and the morphology of the titanium oxide nanoparticles. The study provides a deeper insight into TiO2 nano particle production and their characteristics, thereby emphasizing their suitability for advanced material applications.

Nabothian cysts are non-malignant lesions that occur on the cervix and affect a large percentage of reproductive aged women. They usually occur because of childbirth or minor trauma; most of the time, they are small and asymptomatic and require no treatment. However, large nabothian cysts may vary in appearance and even resemble malignant tumors. Consequently, in order to rule out malignancy, a biopsy is advised. The greatest valuable imaging modalities for cervical cystic lesions are MRI and transvaginal ultrasonography. Nabothian cysts usually don't need any treatment, but if the lesion's nature is unclear and it hurts, surgery may be necessary. In this case study, chronic pelvic pain is described and abnormal uterine bleeding needed surgical intervention because of chronic cystic cervicitis and multiple nabothian cysts accompanied with Leiomyoma accompanied with adenomyosis and endometrial hyperplasia without atypia.

It describes broadening of the semicircle in the complex plane (Nyquistplot) and Bode plots behavior using commercial software Software ZSimpWin 3.22 in the absence and with of corrosion reactions. Before this process, the appropriate modified electrical equivalent circuit had selected where constant phase element had used instead of a capacitor for reach to reality. The result helps to understand the system under study i.e. the change of impedance behavior with electrochemical processes.
