Purpose: to study the dynamics of catalase activity in the blood and liver liver tissues with oxidative stress caused by the modeling of dyslipoproteinemia with the subsequent mechanical trauma of the skeletal muscle.Materials and methods. The study was conducted on white, unconventional sexual healthy rags of six months of age, weighing 200-230 grams, in the amount of 120 pieces contained in standard conditions of vivarium. All animals were divided into four groups, 30 animals in each group. Animals of the first group are intact rats to which no effects were applied. Animals of the second group (regeneration control) had a mechanical dissection in the area of the middle third of the calf muscle of the posterior limb. Animals of 1 and 2 groups were on the standard diet of Vivaria and had free access to water and food. The animals of the third and fourth groups were first modeled by dyslipoprotein for 63 days. All this time, animals received a high -carb and high -fat diet with a weight of dry substances increased up to 30 % and replacement of drinking water with a 20 % fructose solution. After the specified time, the animals of the fourth group were injured by the middle third of the calf muscle of the posterior limb. The activity of catalase was investigated in animals before the start of the experiment, as well as on 1, 3, 5, 14, 21 days of experience according to the standard methodology of Queen M. A. The capture of the material and the removal of rats from the experiment was carried out with accurate observance of all ethical norms applicable to laboratory animals . Under etheric anesthesia, a blood fence was made, and then the liver fence, which was washed with physiological solution and frozen. Then, by mechanical grinding of fabrics weighing 1 g and mixing with 9 ml of Tris Bufer (pH 7.4), homogenates were prepared in an automatic homogen at a speed of 5,000 rpm in a vessel with double walls, constantly cooled by running water.Results. The mechanical trauma of the calf muscle and dyslipoprotemia contributed to the intensification of oxidative processes at the local and systemic levels of the body, but the combination of these facts was characterized by extremely intense oxidative stress and led to a decrease in the activity of catalase in the blood and liver tissues.

Abstract
The changing dynamics of masculinity in a post-feminist world entails an analysis of the representations of boyhood and masculinity in varied temporalities and cultures. Primarily through the theories of Judith Butler, Raewyn Connell, and David Buchbinder, this article explores the problem of men and their social roles. It discusses the issue of double vulnerability faced by gay men in a patriarchal social dynamic that affects their identity construction. Through the spectacle of textual analysis, we examine Nemat Sadat's, The Carpet Weaver (2019), the tale of Kanishka, a gay boy living in a war-torn Afghanistan, and his migration to America, which aids in shaping his identity. We also examine the intersections of the masculine image within a political war zone, exploring the subject of gendered violence against men.
Crime as Protest, Protest as Crime
Authors: Travaglino Giovanni A. , d'Aniello Cristina 
Published: May 2023

Abstract
This special issue explores the complex and multifaceted relationship between crime and protest. Crime may in some circumstances be considered a legitimate form of resistance against oppressive authorities. It may also be seen as an unacceptable form of violence or a symptom of social disorganization. Similarly, while protest is a tool for promoting social justice, it may be criminalized and treated as a threat to public order. The articles in this issue draw on a range of theoretical and methodological approaches to examine various aspects of the relationship between crime and protest. They explore strategies used by governments to suppress dissent, the relationship between moderate and radical protest actions, and the ways in which marginalized groups challenge the designations of illegality by immigration regimes. The articles demonstrate how crime and protest are deeply intertwined, and they provide new insights into the complexities of social activism and the challenges faced by those who engage in it.

Arap gramerine dair eser yazan müellifler, temelde aynı konuları ele almış olsalar da konu tasnifi bakımından hepsinin aynı metodu izlediği söylenemez. Zira konuların tasnifinde i‘râb, ‘âmil, kelime çeşidi, ‘amel, güçlülük – zayıflık ve cümle çeşidi gibi birçok unsur etkili olmuştur. Her müellif kendi nahiv felsefesine, eseri telif etme amacına, dönemin ilmî anlayışına, konularda ön plana çıkarmak istediği hususlara ve muhatap kitlenin bilgi düzeyine uygun gördüğü unsurları dikkate almış ve konu tasnifini de bu bağlamda yapmıştır. Bu da konu tasnifinde izlenen metotların kısmen veya önemli ölçüde birbirinden farklı olmasına neden olmuştur.
Mecduddîn İbnu’l-Esîr, (öl. 606/1210) el-Bedî‘ fî İlmi’l-Arabiyye adlı eserinde diğer müelliflerden çok farklı bir tasnif sistemini benimsemiştir. Çünkü müellifler konuları tasnif ederken genelde en önemli ve asli hususları esas almışlardır. Konuyla ilgili fer‘î meseleleri ise ya metin içinde ele almışlar ya da onlara hiç değinmemişlerdir. Oysa Mecduddîn İbnu’l-Esîr, en ayrıntılı ve fer‘î meseleleri dahi konu tasnifinde etkili birer unsur olarak dikkate almıştır. Bu nedenle son derece teferruatlı ve çok farklı faktörlere dayalı bir tasnif sistemini geliştirmiştir. Çalışmamızda Mecduddîn’in tasnif sistemi; ana bölümlerin tasnifi, bâbların kendi içindeki tasnifi ve iç tasnif şeklinde üç başlık altında ele alınmıştır. Mecduddîn’in konu tasnifinde dikkate aldığı başlıca faktörleri saptamak, bu sistemin olumlu ve olumsuz taraflarını ortaya koymak, hangi muhatap kitlesine uygun olduğunu tespit etmek çalışmamızın hedeflerindendir.

Introduction: Functional disorder of the placenta is the principal cause of fetal growth restriction (FGR), usually cured with suitable clinical treatment and good nursing. However, some FGR mothers still give birth to small for gestational age (SGA) babies after treatment. The ineffectiveness of treatment in such a group of patients confused physicians of obstetrics and gynecology.Methods: In this study, we performed a microRNA-messenger RNA integrative analysis of gene expression profiles obtained from Gene Expression Omnibus. Differentially expressed genes were screened and checked using quantitative polymerase chain reaction. Target genes of significantly changed microRNA were screened and enriched for Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses. Function of the obtained microRNA-messenger RNA was evaluated using HTR-8/SVneo trophoblast cells, human umbilical vein endothelial cells, and heterozygote male mice.Result: MiR-155-5p was upregulated (p = 0.001, fold-change = 2.275) in fetal-side placentals. Among the hub genes identified as key targets for miR-155-5p in fetal reprogramming, Smad2 was downregulated (p = 0.002, fold change = 0.426) and negatively correlated with miR-155-5p expression levels (r = −0.471, p &lt; 1.0 E – 04) in fetal-side placental tissues. The miR-155-5p mimic blocks Smad2 expression and suppresses villous trophoblast cell and endothelial cell function (proliferation, migration, and invasion), indicating a close relationship with placental development. Luciferase assays further confirmed the targeting of miR-155-5p to Smad2. Furthermore, Smad2+/− heterozygote male mice were born small with low body weight (p = 0.0281) and fat composition (p = 0.013) in the fourth week post-natal.Discussion: We provide the first evidence of the role of the Smad2/miR-155-5p axis in the placental pathologies of FGR. Our findings elucidate the pathogenesis of FGR and provide new therapeutic targets.

Published: May 2023

Red mud (RM) a solid waste generated by the bauxite smelting industry, is a rich source of metal resources, especially Ti, and its recycling can bring significant environmental and economic benefits. In this study, precious metal Ti was efficiently recovered from red mud using a coupled acid leaching and boiling route for the effective separation of low-value metals. The red mud which contained mainly 10.69% Si, 12.1% Al, 15.2% Ca, 10.99% Fe, and 4.37% Ti, was recovered in five steps. First, a nitric acid solution was used to leach the metals in multiple stages, resulting in an acidic leach solution with high concentrations of Fe, Al, Ti, and Ca ions 2.7 g/L, 4.7 g/L, 5.43 g/L, and 1.8 g/L, respectively. Then, a small amount of sucrose was added as a catalyst to recover Ti from the leach solution under hydrothermal conditions, resulting in the targeted recovery of 98.6% of Ti in the form of high-purity anatase while Fe, Al, and Ca remained in the solution. Next, the Fe in solution was separated as hematite products at a temperature of 110°C and a reaction time of 4 h. Similarly, the Al in the solution was separated and precipitated as boehmite by heating it at 260°C for a reaction time of 20 h. Finally, the remaining Ca in solution was recovered by simple pH regulation. Economic accounting assessment showed that the method yields $101.06 for 1 t of red mud treated, excluding labor costs. This study provides a novel approach to recover precious metals from metal wastes through the whole process resource recovery of solid waste red mud.

IntroductionThe aims of this study were to determine the immune response and the anticoccidial activity induced by Moringa oleifera and Vernonia amygdalina leaves in rabbits infected with Eimeria magna and Eimeria media.MethodsThirty-five-day-old rabbits, free from coccidia, were infested with 2.103 oocysts of Eimeria magna and Eimeria media, then received the acetone extract of the leaves of Moringa oleifera and Vernonia amygdalina at different doses by oral gavage.Results and discussionThe inhibition of the excretion of oocysts was evaluated by the McMaster technique and the levels of cytokines (IL-4 and IL-12) and immunoglobulin IgG were assayed by the ELISA method. The in vivo efficacy on E. magna and E. media oocysts was 95.43% and 96.53% for Moringa oleifera and Vernonia amygdalina at 1000 mg/kg bw against 98% for the positive control. Interestingly the plant extracts increased the production of interleukin (IL) and immunoglobulins (Ig) compared to controls. Plasma IL-4 levels (pg/ml) in rabbits were 128.94 and 131.38; those of IL-12 (pg/ml) were 395.55 and 426.56, and then for those of IgG (μg/ml) were 14.70 and 13.94 respectively with the acetone extracts of Moringa oleifera and Vernonia amygdalina on D14 PT at 1000 mg/kg bw. This study indicates that Moringa oleifera and Vernonia amygdalina can be used as an alternative to synthetic anticoccidials. These plants could be used to increase the resistance of the immune system of rabbits to infestations of Eimeria species in rabbit farms.
Adaptive vertical-deformation field estimation and current tectonic deformation significance analysis in Shanxi rift valley
Authors: Liu Ruichun , Zhang Jin , Guo Wenfeng , Chen Hui 
Published: May 2023

The Shanxi rift valley is a continental rift system that is characterized by mantle uplift, crustal thinning, and tectonic deformation. A continuous, vertical crustal-deformation field can elucidate the constraints for understanding the mechanisms currently driving the deformation of the rift. Accordingly, we acquired and processed data from 250 continuous and mobile GPS stations located in the Shanxi rift valley and its surrounding region. Accounting for the influence of fault activity, we established the vertical crustal-deformation field of the Shanxi rift valley as a continuous function of space, using an adaptive least-squares collocation method. The main research findings are stated as follows: 1) the adaptive least-squares model yielded a reliable interpolation prediction results with adequate robustness, even for relatively sparse actual observation data. 2) The current general deformation pattern of the Shanxi rift valley exhibits an uplift of the mountainous regions on both sides and subsidence of the central basin. The average uplift rate of the mountain area is 2–3 mm/a, and the subsidence rate of the basin is not uniform and is positively correlated with the spatial distribution of the Cenozoic sediment thickness. However, in certain areas, a high subsidence rate of 10–30 mm/a is associated with human activities such as groundwater exploitation. 3) In summary, the current vertical crustal deformation occurring in the Shanxi rift valley correlates with the pattern over a time scale of millions of years. Overall, it is controlled by regional geological structure pattern, and is influenced by nonstructural factors in the shallow crust, exhibiting both complex and orderly characteristics in its spatial distribution.

BackgroundThere is a higher risk of preterm delivery (PTD) in singleton live births conceived after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) compared with spontaneously conceived pregnancies. The objective of our study was to build a predictive nomogram model to suggest the possibility of PTD in singleton pregnancies after IVF/ICSI treatment.Method11513 IVF/ICSI cycles with singleton live births were enrolled retrospectively. These cycles were randomly allocated into a training group (80%) and a validation group (20%). We used the multivariate logistics regression analysis to determine prognostic factors for PTD in the training group. A nomogram based on the above factors was further established for predicting PTD. Receiver operating characteristic curves (ROC), areas under the ROC curves (AUC), concordance index (C-index), and calibration plots were analyzed for assessing the performance of this nomogram in the training and validation group.ResultsThere were fourteen risk factors significantly related to PTD in IVF/ICSI singleton live births, including maternal body mass index (BMI) &gt; 24 kg/m2, smoking, uterine factors, cervical factors, ovulatory factors, double embryo transferred (DET), blastocyst transfer, FET, vanishing twin syndrome (VTS), obstetric complications (placenta previa, placenta abruption, hypertensive of pregnancies, and premature rupture of membrane), and a male fetus. These factors were further incorporated to construct a nomogram prediction model. The AUC, C-index, and calibration curves indicated that this nomogram exhibited fair performance and good calibration.ConclusionsWe found that the occurrence of PTD increased when women with obesity, smoking, uterine factors, cervical factors, ovulatory factors, DET, VTS, and obstetric complications, and a male fetus. Furthermore, a nomogram was constructed based on the above factors and it might have great value for clinic use.
