Five new tetrasubstituted imidazoles were designed with outstanding yields(83%-92%) in the occurrence of ionic liquid-based-pyridinium as a catalyst. The constructions of all synthesized derivatives were established by spectral tools and their purities were verified using thin-layer chromatography(TLC), displaying single-spot. The performance of corrosion protection of the prepared imidazole derivatives was examined theoretically and practically for acid steel corrosion. The experimental study was conducted by electrochemical(electrochemical impedance spectroscopy(EIS) and Tafel polarization(PPS)) *** findings from the used approaches concluded that the synthesized compounds were wellorganized inhibitors with an efficiency of 90.7%-98.5% at 50℃ and 0.7 mmol·L^(-1). The Tafel polarization results indicate the protective action of the additives was under mixed-monitoring. The additive adsorption on the electrode interface performed as a distinguished aspect for protection. The surface exploration on the blank and protected metal was completed by field emission scanning electron microscopy(FESEM). Computational studies by Monte Carlo(MC) simulation and quantum chemical calculation(DFT)were related to practical findings. The corrosion protection adsorption mechanism was reinforced by the preferable fitted Langmuir isotherm model. All findings from the applied-inspected approaches alternately confirm each other.

Three novel amprolium HCl（AMP）-selective electrodes were investigated with 2-nitrophenyl octylether as a plasticiser in a polymeric matrix of polyvinyl chloride（PVC）. Sensor I was fabricated using potassium tetrakis（4-chlorophenyl） borate（Tp ClPB） as a cationic exchanger without incorporation of an *** Ⅱ used 2-hydroxy propyl β-cyclodextrin as an ionophore while sensor Ⅲ used p-tert-butylcalix[8]arene as an ionophore. The three proposed sensors showed Nernestian response slopes of 29.2±0.8,29.3±0.6 and 30.2±0.4 m V/decade over the concentration range from 10–6 to 10–2 mol L_（-1）,respectively. The proposed sensors displayed useful analytical characteristics for the determination of AMP in bulk powder, different pharmaceutical formulations, and chicken liver and in the presence of ethopabate. The proposed method was validated according to ICH guidelines for its linearity, accuracy,precision and robustness.

Objective: To evaluate the antioxidant, immunomodulatory and anti-inflammatory activities of pyrrolidine dithiocarbamate and saxagliptin in rats with thioacetamide-induced ulcerative colitis. Methods: Animals were orally administered with a vehicle, sulfasalazine(500 mg/kg), pyrrolidine dithiocarbamate(100 mg/kg), and saxagliptin(10 mg/kg) for two weeks. Ulcerative colitis was induced by a single intrarectal instillation of thioacetamide on day 8. Colon samples were collected to assess mitogen-activated protein kinase(MAPK), phosphorylated extracellular signal-regulated kinase(ERK), c AMP response element-binding protein(CREB), interleukin-12(IL-12), caspase-3, β-defensin, inducible nitric oxide synthase(i NOS) and glucagon like peptide-1(GLP-1). Moreover, histopathological examination was performed. Results: Rats treated with thioacetamide caused increases in colonic MAPK, phosphorylated ERK, CREB, caspase-3, IL-12, β-defensin, i NOS, as well as decreases in body weight and GLP-1. In addition, distortion of colonic structure was found by histopathological examination. Pyrrolidine dithiocarbamate and saxagliptin mitigated colitis severity by improving body weight decrease and GLP-1, and reducing colonic MAPK, phosphorylated ERK, CREB, caspase-3, IL-12, β-defensin and i NOS. Conclusions: Pyrrolidine dithiocarbamate and saxagliptin are efficient against thioacetamide induced colitis through improving inflammatory and oxidative changes.

伊维菌素是美国食品药品监督管理局（FDA）批准的抗寄生虫剂，具有抗病毒和抗炎特性。尽管最近有研究表明伊维菌素在呼吸系统损伤中可能具有抗炎活性，但其对肺纤维化（PF）的潜在影响尚未得到验证。本研究旨在探讨伊维菌素（0.6 mg/kg）在PF大鼠模型中减轻博来霉素诱导的生化紊乱和组织学变化的效果。这可用于验证伊维菌素作为治疗特发性PF在临床上的效用。在本研究中，伊维菌素减轻了博来霉素诱发的肺损伤，表现为炎症细胞浸润减少以及炎症和纤维化评分降低。值得注意的是，伊维菌素减少了胶原纤维的沉积并抑制了转化生长因子-β1(TGF-β1)和纤连蛋白的表达，突显了其抗纤维化活性。本研究首次揭示伊维菌素可以抑制NOD样受体家族含吡啶结构域蛋白3(NLRP3)炎症小体，表现为NLRP3和含有半胱天冬酶募集结构域的凋亡相关斑点样蛋白（ASC）基因的表达减少，以及白细胞介素-1β(IL-1β)水平的下降。此外，伊维菌素抑制细胞内核因子-κB(NF-κB)和缺氧诱导因子-1α(HIF-1α)蛋白的表达，同时降低氧化应激和凋亡标志物的水平。本研究表明，伊维菌素可以改善博来霉素引起的肺部炎症和纤维化，并且部分功能是通过下调TGF-β1和纤连蛋白以及通过调节HIF-1α和NF-κB的表达抑制NLRP3炎性小体来介导的。

Background: Complications linked to postpartum & pregnancy are one of the major causes of female death. In order to understand the causes of complications and encourage women to take sufficient action in order to receive emergency treatment, a critical step should therefore be taken to minimize complications related to pregnancy, in order to ensure the safety of both women and newborns. Aim of the work: Evaluate the effectiveness of the education programs for pregnant women on obstetric danger signs in rural areas and help minimize the incidence of pregnancy loss and comorbidities. Methods: A quasi-experimental design on 70 women from a population of through 372 women in six-month in antenatal clinics recruited from the previously mentioned settings with pre- and post-test was conducted at antenatal clinics (M.C.H centers) affiliated to the available geographical health zones in el-fayoum rural area including: Al-sheikh hassan at sanorse.
