Vernonia amygdalinaas has been found to lower blood pressure, reduces body weight, andimprove fertility. However, its effects on oxidative stress imposed by opiods has yet to be determined.This research therefore aims to investigate the attenuating potentials of Vernonia Amygdalina ethanol leafextract on oxidative stress biomarkers, following the administration of graded doses of tramadol. FreshVernonia amygdalina leaf were extracted using ethanol and the extract were stored for use in theexperiment. Thirty (30) mature male Wistar rats weighing were used for study. The animals wereacclimated for seven days, divided into six groups of five animals in each group. Group 1 received 0.5 mlof normal saline. Group 2, 3, 4, 5 and 6 were given tramadol 30 mg/kg body weight respectively for 12weeks, however, group 6 was withdrawn after 6 weeks of tramadol administration. Group 3, 4, 5 and 6also received ethanol extract of Vernonia amgydalina at a dose of 250 mg/kg, 500 mg/kg, and 1000mg/kg body weight respectively for 12 weeks. At the end of the 12 weeks treatment period, the rats wereeuthanized by cervical dislocation; blood samples were collected and centrifuged to obtain serum forbiochemical analysis. Brain, Liver, Pancreas, kidney and testes were excised for biochemical evaluation.The data obtained were analyzed by comparing the values for individual controls for different treatmentgroups and the results were expressed as mean values ± standard mean error (mean ± SEM). Using thestudent's t-test, ANOVA variance analysis, and the results were considered significant at P-values of lessthan 0.01 (P<0.01) using SPSS version 23 software, significant differences between control andexperimental groups were measured. Results show a significant increase in the activities of non-enzymicantioxidants (Vitamins C, E, and K), carotenoids antioxidants (beta-carotene, lutein, lycopene, andzeaxanthin), thiol antioxidants (Glutathiones, Glutathione peroxidase, and Lipoic acid), oxidoreductaseantioxidant (Catalase), metaloenzyme in all tissues of rats given tramadol and treated with VernoniaAmygdalina ethanol leaf extract when compared with to the group 2 rats that received only tramadol.Compared to the other groups, group 4 rats likewise show a more pronounced improvement. Whencompared to group 2 rats that got only tramadol, there was a significant decrease in Malondialdehydeactivities in all tissues of rats given tramadol and treated with Vernonia Amygdalina ethanol leaf extract.Vernonia amygdalina was found to be efficacious in reducing ROS-induced tramadol-induced chronictoxicity and organ impairment in Wistar rats. It is suggested that the bioactive chemicals in Vernoniaamygdalina that function as an adjunct in the chronic therapy of organ harm caused by opioid prescriptionaddiction be identified, isolated, and employed again to validate the findings of this study.
人们发现扁桃苦苷可以降低血压，减轻体重，提高生育能力。然而，其对阿片类药物引起的氧化应激的影响尚未确定。因此，本研究旨在研究苦杏仁醇叶提取物在给药后对氧化应激生物标志物的衰减电位。用乙醇提取鲜扁桃叶，提取液保存备用。采用称重的成年雄性Wistar大鼠30只进行研究。这些动物被分成六组，每组5只动物。1组给予生理盐水0.5 ml。组2、组3、组4、组5、组6分别给予曲马多30 mg/kg体重，连续用药12周，组6用药6周后停药。组3、组4、组5、组6同时给予水蛭乙醇提取物，剂量分别为250 mg/kg、500 mg/kg、1000mg/kg体重，持续12周。12周治疗期结束时，颈椎脱臼处死大鼠;采集血样，离心提取血清进行生化分析。切除脑、肝、胰、肾、睾丸进行生化评价。比较不同治疗组的个体对照值，对所得数据进行分析，结果用平均值±标准平均误差(mean±SEM)表示。采用学生t检验、ANOVA方差分析，并以P值<0.01 (P<0.01)为显著性，采用SPSS version 23软件，比较对照组与实验组之间的显著性差异。结果表明，与只服用曲马多的2组大鼠相比，服用曲马多和苦杏仁叶提取物的大鼠各组织中非酶抗氧化剂(维生素C、E和K)、类胡萝卜素抗氧化剂(β -胡萝卜素、叶黄素、番茄红素和玉米黄质)、硫醇抗氧化剂(谷胱甘肽、谷胱甘肽过氧化物酶和硫酸)、氧化还原酶抗氧化剂(过氧化氢酶)、金属酶的活性显著增加。与其他组相比，第4组大鼠同样表现出更明显的改善。与仅给曲马多组大鼠相比，给曲马多组大鼠和苦杏仁叶乙醇提取物组大鼠各组织丙二醛活性均显著降低。研究发现苦杏仁能有效降低ros诱导的曲马多致Wistar大鼠的慢性毒性和器官损害。因此，我们建议鉴定、分离并再次利用苦杏仁中的生物活性化学物质，以辅助治疗阿片类药物处方成瘾引起的器官损害。

In this paper, we propose on type of Dunford integration in the concept of ideal convergenceThis wants to construct a new convergence of functions in Banach space to definite the measurablefunctions. The main result is construction on the type of Dunford as the Ideal integral. Ideal Dunfordintegral is an application of the convergence ideal in integration but weak integration. For this been followedthe usual route by first introducing the ideal Dunford integral and demonstrating for the ideal Dunfordintegral the most important statements related to it in the classical case. In this paper, we prove if thefunction f is Dunford integrable then it is ideal Dunford integrable, but conversely, this is not true. Thisgives the meaning of the extension of Dunford integration in our article. We are motivated by this by oneimportant example published by Schvabik and Guoju, [20].

The Southeast Anatolian Orogenic Belt (SAOB), one of the most important belts in Turkey, islocated north of the Bitlis-Zagros Suture Zone. Major iron mineralizations are also observed along this belt.The Pertek (Tunceli) region is one of the dominant Fe-Skarn mineralisations. Keban Metamorphites ofPermo-Carboniferous age forms the basement of the region. It is mainly represented by metacarbonates,marbles and schists, respectively. This unit is also cut by intrusive rocks from the Upper Cretaceous ElazığMagmatic Complex (EMC). Tertiary volcanic rocks and sedimentary rocks also overlie both units withangular unconformity. Fe-Skarn was formed at the contact of carbonates belonging to KebanMetamorphites and diorites belonging to EMC. Macroscopically, magnetite crystals and garnet can beobserved in the skarn formation, which is easily distinguished by its colour. Polarizing microscopy revealedquartz, calcite, garnet, pyroxene, chlorite and opaque minerals. X-ray diffraction (XRD) analysis revealedthat the garnet is andraditic, and the ore minerals are magnetite and hematite. In the ore microscopy, it wasdetermined that magnetite was first transformed into hematite and then hematite into goethite. Regardingthe major oxide concentrations of the samples taken from the region, it was determined that the Fe2O3 valuereached a maximum of 60% (average 21.94%), SiO2 (average 38.20%) and CaO (average 23.58%)concentrations were high, and Al2O3 concentration was generally low. Al2O3 concentration reaches 17.96% in the sample where clayification is common. The findings of this study provide a baseline foridentifying the origin of the Pertek Fe-Skarn formation.

The outbreak of the Covid-19 pandemic has had a profound impact on the global tourismindustry, including in Türkiye. The tourism sector, which was a significant contributor to Türkiye'seconomy, has faced unprecedented challenges, particularly in terms of employment. This abstract aims toexplore the impact of Covid-19 on tourism employment in Turkiye by analyzing key trends, data, andresearch.The COVID-19 pandemic has had a profound impact on the global tourism industry, and Turkey, a populartourist destination known for its rich history, stunning landscapes, and warm hospitality, has not beenimmune to its effects. As the virus spread and countries implemented travel restrictions and lockdownmeasures to curb its spread, Turkey's tourism industry faced significant challenges and disruptions,resulting in far-reaching consequences for the economy and communities dependent on tourism.

In this study, Polyaniline/ceria nanoparticles (PANI/CeO2) nanocomposite (NPs) were preparedby in situ polymerization of aniline in the presence of CeO2 NPs . Ceria nanoparticles were produced viathe precipitation of cerium Ce(NO3)3.6H2O in water where the average hydrodynamic diameter of theobtained nanoparticles was about 8 nm (determined by nanosizer) . Infrared spectroscopy “FTIR” and whitelight interferometry analysis were used to characterize the obtained PANI/CeO2 and also theelectrodeposited coatings. To overcome the low solubility of the polymer /ceria nanoparticles, thecomposites was dissolved in dimethyl sulfoxide solvent under ultrasonic stirring. The electrochemicalbehavior of zinc substrate in the corrosive medium with and without PANI / CeO2 addition was studiedusing d.c polarization techniques and electrochemical impedance spectroscopy “EIS”. All the obtainedresults have shown the good behavior of PANI/CeO2 in the protection of zinc against corrosion. Indeed, theaddition of 66 ppm of PANI / CeO2 to the aggressive solution 0.5N NaCl provides to the substrate anelectrochemical efficiency about of 77.74%. It has been shown that PANI /CeO2 acts on the anodic process.the hybrid PANI/ CeO2 NPs can be considred as an intersting way to enhance the protection performanceof the PANI/CeO2 on zinc
