Growth regulators alter the development and metabolism of lemon balm seedlings cultured in vitro
Authors: da Silva Leila I. , Magalhães Hélida M.
Published: May 2023

ABSTRACT Melissa officinalis L., popularly known as lemon balm, is an aromatic plant widely used in medicine, cosmetics, and pharmaceutical industries for its essential oil rich in phenylpropanoids, terpenes, and phenolics. This study aimed to assess the effect of growth regulators on the development and physiological and biochemical metabolism of M. officinalis cultured in vitro. Seeds were inoculated in Murashige and Skoog medium and added with the regulators 6-benzylaminopurine (BAP) and 1-naphthaleneacetic acid (NAA) according to six different treatments. After 90 days of culture, plants were evaluated for growth and biochemical and physiological parameters (flavonoids, anthocyanins, and chlorophyll). The balance between regulators interfered with plant growth, which increased in the presence of 0.2 mg L-1 BAP. In this treatment, the plants had greater growth with more leaves, and the biomass production of shoots and roots was higher than the control. Growth regulators did not influence nitrogen assimilation or flavonoid production; however, total chlorophyll and anthocyanin indexes were enhanced by treatment with BAP at concentrations ranging from 0.2 to 0.5 mg L-1. Auxin treatment did not improve root production or growth but favored callus formation when combined with 0.5–3.0 mg L-1 BAP. The results indicate that high BAP concentrations (above 1.0 mg L-1) should not be used in in vitro production of lemon balm.

ABSTRACT Soil quality, measured through its chemical, physical and microbiological attributes, changes as a result of anthropic sensations and becomes an important tool to assess environmental quality. The objective of this study was to determine and evaluate the Quality Index of an Ultisol in a long-term (17-yr) plots under different management systems in the Coastal Tablelands of Sergipe State, in Northeastern, Brazil. Main effects were conventional tillage (CT), no-tillage (NT), and minimum tillage (MT) distributed cultivated strips with corn as the main crop. Split-range treatments were randomly distributed and cultivated with cowpea beans (Vigna unguiculata), sunn hemp (Crotalaria juncea), pigeon pea (Cajanus cajan), and millet (Pennisetum glaucum). A forest soil was used as reference, compared to the soil samples of the cultivated area. The Soil Quality Index (SQI) for the 0-0.10 m layer was calculated by the additive method. There were changes in soil properties between the different management systems, and between the experimental soil and the reference area. The highest SQI was obtained from the forest area (67.1) followed by the NT treatment (65.5), MT (65.1) and CT treatment (61.0). The lowest SQI was observed in the CT treatment previously cultivated with pigeon pea (56.5). Among the evaluated soil functions, maintenance of homeostasis had the greatest influence on the SQI. The higher acidity of the forest soil helps to explain the origin of the limitations of the soil in the cultivated area that occupies the same type of soil, tolerated by the adoption of conservationist managements.

Published: May 2023

ABSTRACT The evaluation of the physical attributes of the soil in cultivated areas is essential for understanding the impacts of agricultural operations, especially those with intense machine traffic. Therefore, the present study aimed to evaluate the physical attributes of the soil submitted to silage with different mechanized sets. A randomized block design was adopted with three treatments: forage harvester with a one-row cutting platform (T1), forage harvester with a three-row cutting platform (T2), and T2 with a forage harvester with a conveyor wagon. Before ensiling and 24 hours after the operation, intact samples of soil classified as Latossolo Vermelhoamarelo álico, intact, were collected to determine the micro, macro, and total porosity, soil density, and volumetric soil water content according to the methodology proposed by the Brazilian Agricultural Research Corporation (Embrapa). After ensiling, the resistance to soil penetration was measured with an electronic manual penetrometer, before and after ensiling, at the A horizon of the soil in the layers of 0.0-0.2 m and 0.2-0.4 m. We analyzed the data by establishing the confidence interval using the t-test at 10% probability. The sets reduce the macroporosity and total porosity of the soil in the 0.0-0.2 m and 0.2-0.4 m soil layers. T2 promoted greater total density in the 0.0–0.2 m layer. The silage increased the resistance to soil penetration to a depth of 0.15 m.

Published: May 2023

ABSTRACT Tobacco production in Brazil is an essential source of income for many families, especially in the southern region. However, it is subject to attack by pests and diseases, such as the fungus gnats insect. To control this pest, the mite Stratiolaelaps scimitus is found in Brazilian soil, which has a predatory potential to fungus gnats. This study aimed to evaluate the use of S. scimitus as an insect control agent, compared to chemical control, in the production of tobacco seedlings in the floating system. The experiment was carried out on a farm in Crissiumal-RS, in a randomized block design, with four replications: T1= control, T2= chemical control based on Imidacloprid and Azadirachtin, and T3= S. scimitus. To analyze the control efficiency, adult insects were captured at different times, and the biological control did not differ from the chemical control. The biological treatment made it possible to reduce the use of chemical products. Concomitantly, questionnaires verified that producers are well accepting the new control model. Therefore, using S. scimitus could reduce the proliferation of fungus gnats in the production of tobacco seedlings in the floating system, but more studies need to be carried out for a better evaluation.

Published: May 2023

ABSTRACT The ranking of seed lots is a fundamental process for all companies in the seed industry. This work aims to demonstrate data mining methods for ranking sorghum seed lots during the seed processing through analysis of quality control data. Germination and cold tests were performed to verify the physiological quality of the lots. Seed samples from each lot were evaluated in two moments: post-cleaning and finished product (ready for marketing). The results after pre-processing totaled 188 rows of data with six attributes, encompassing 150 lots accepted for marketing, 6 rejected, and 32 intermediate lots. The classifiers used were J48, Random Forest, Classification Via Regression, Naive Bayes, Multilayer Perceptron, and IBk. The Resample filter was used for adjustment of the data. The k-fold technique was used for training, with ten folds. The metrics of Accuracy, Precision, Recall, F-measure, and ROC Area were used to verify the accuracy of the algorithms. The results obtained were used to determine the best machine-learning algorithm. IBk and J48 presented the highest accuracy of data; the IBk technique presented the best results. The Resample filter was essential for solving the data imbalance problem. Sorghum seed lots can be classified with great accuracy and precision through artificial intelligence and machine learning technique.
Modeling water quality in a tropical reservoir using CE-QUAL-W2: handling data scarcity, urban pollution and hydroclimatic seasonality
Authors: Lima Neto Iran Eduardo
Published: May 2023

ABSTRACT This study applies a 2-D hydrodynamic model (CE-QUAL-W2) for simulating water quality dynamics in a tropical reservoir located in Fortaleza, Ceará, Brazil. While rainfall concentrates basically in the first semester, this reservoir receives untreated sewage from an urban catchment throughout the year. To deal with data scarcity, model simplifications are justified and several adjustments are carried out, so that only the parameters temperature (T), dissolved oxygen (DO), chlorophyll a (Chla) and phosphate (PO4) are kept in the modeling process. Additionally, different assumptions are performed regarding the time-evolution of reservoir inlet concentrations: constant values, step and linear variations. The results indicate that the simplified model can predict well the seasonal variations of T, DO, Chla and PO4. The best fitting between model results and measurements are obtained with the assumption of linear variation in inlet concentrations, followed by the assumptions of constant values and step variation. Moreover, the results reveal that while PO4 presents a complete mixing behavior with a clear increase in concentration from the wet to the dry season, T, DO and Chla show an alternating stratification-destratification patter during the day-night but without relevant variations throughout the year. Model simulations of different scenarios also indicate a significant reduction in Chla concentration in the second semester, but external load reduction has a stronger impact on model outputs than hydroclimatic variability. The modeling approach developed in the present study is proposed as a simple way to cope with data scarcity, urban pollution and hydroclimatic seasonality in tropical reservoirs.

Abstract The expansion of residential areas has increased the demand for exotic and increasingly compact landscape plants. In this context, this work aimed to evaluate the effects of paclobutrazol (PBZ) and the timing of ethylene application on growth reduction and flowering anticipation in ornamental pineapples grown in pots. The randomized block design was used with factorial arrangement (2 x 5) and 4 replications and 4 plants per plot. The primary treatments are the presence and absence of PBZ. The secondary treatments were five times of floral induction with ethylene: 90; 120; 150; 180; 210 days after transplanting (DAT) the seedlings into the pots. It was evaluated the variables: height ratio between the heights of the pot and the plant; rosette diameter; leaves length ‘D’ and flowering index. At 255 DAT, although the plants did not respond to floral induction with ethylene, only those treated with PBZ were more compact and had different characteristics such as smaller size and a ratio below 1/3 of the height of the vase in relation to the plant that to favor its commercialization, in pot.

Abstract In order to establish a link between the evolutionary history and the photochemical attributes, measurements of chlorophyll (Chl) a fluorescence were made in Cattleya warneri, C. shofieldiana and C. harrisoniana exposed to high irradiance for 5, 35, and 120 min (hereafter referred to as treatments T5, T35, and T120, respectively). The following questions are addressed: (1) Is the increased energy dissipation enough to counterbalance the excess energy that drives photosynthesis at different times of high irradiance exposure? (2) Is there an influence of the incidence and duration of light radiation on Cattleya species in full sunlight, compared to Cattleya species submitted to low irradiance? Higher relative variable fluorescence at the J-step (Vj) values followed by the lower quantum yield of electron transport (ψEo) indicate the accumulation of reduced Quinone A (QA) proportionally of sunflecks exposure time in C. warneri. The higher performance index (PIABS) and plasticity index values in C. schofieldiana indicate higher efficiency in modulating the photosynthetic apparatus under sunflecks. C. harrisoniana shows the lowest plasticity index, suppression of maximum fluorescence (Fm), and no recovery of PIABS after sunflecks. This study evidences the importance of physiological plasticity in the current geographic distribution of Cattleya in response to light pulses in species derived from fragmented habitats and the maintenance of shade to species of more primitive clades.
Effects of dormancy breaking methods on germination of Cercis siliquastrum and Spartium junceum and seedling growth
Authors: Taghizadeh Mina , Sajadi Fahimeh Sadat
Published: May 2023

Abstract Seed dormancy is a mechanism of long survival that is ecologically important for seed propagation and dispersal and the expansion of plant populations. The impermeability of the seed coat in the Fabaceae family is due to a layer of sclerotic cells. Two experiments were conducted to investigate the effect of different seed treatment on germination parameters and seedling growth in Cercis siliquastrum and Spartium junceum. Experimental treatments comprised of chemical and thermal scarification treatment consisting of boiling water (2, 5, 10 min), H2SO4 (30, 60 min) and GA (0, 500 and 1,000 mg L−1) in C. siliquastrum and boiling water (2, 5, 10 min), H2SO4 (2, 5 min) in S. junceum. The results presented here indicate that chemical scarification by soaking in sulfuric acid for 30 min and 2 min in C. siliquastrum and S. junceum, respectively were the most efficient methods to breaking the seed dormancy. The application of these methods promoted the highest values of indices seedlings. In the light of the found results, it revealed that C. siliquastrum and S. junceum seeds are affected by a coat dormancy, which can be removed by a chemical-thermal scarification with sulfuric acid and boiling water. The data obtained contribute to a better comprehension of propagation and establishment of these shrubs ornamental by seedling.

Published: May 2023

Abstract: Aim Evaluate the structure of the aquatic macrophytes assembly of the Jacarecica II Dam, Areia Branca, Sergipe, and verify if distance from the margin is a driver for species richness, and composition in this environment. Methods We settled transects where we plotted quadrats and subplots. The transects were perpendicular in relation to the reservoir margin, and the first quadrat was placed on the margin with the four following ones completely over the water surface. We estimated cover area for each macrophyte species in each quadrat. Each species was also classified according to its life form. We calculated community indexes and tested the influence of the distance from the margin on the structure of macrophyte assemblies. Results We sampled 10 emergent and four free-floating species, resulting in a richness of 14 species. The species with higher importance value were weedy and ruderal species (Salvinia auriculata and Eichhornia crassipes). The distance to the margin caused changes in macrophyte assembly and presented negative relation with species richness. Conclusions The studied assembly presents few species, with some presenting great dominance. This dominance reflects the anthropization of these habitats. Besides, the species composition and richness are modified in the sense that emergent and free-floating species co-occur in marginal quadrats, but only free-floating species occur in quadrats that are in areas that are more distant from the reservoir margin.

Published: May 2023

Este trabalho discute a interação entre origem social e desempenho escolar nas probabilidades de acesso ao ensino superior no Brasil no auge da política expansionista que caracterizou o sistema educacional brasileiro desde a década de 1990. Especificamente, procuramos responder três perguntas: (a) como renda familiar e desempenho se combinam na estruturação das chances de acesso dos jovens? (b) até que ponto a nota pode compensar uma renda baixa ou, ao contrário, a renda familiar compensar desempenhos insuficientes na prova? (c) como essas desigualdades se articulam com a segmentação do ensino superior entre os setores público e privado? Os dados derivam de um painel de egressos do ensino médio em 2012 acompanhados por cinco anos após a conclusão da educação básica, com base em cruzamentos de registros administrativos. Os resultados indicam que para o acesso ao setor público - majoritariamente gratuito e composto por instituições academicamente seletivas - o desempenho é o preditor mais importante, independentemente da origem socioeconômica do candidato. O mesmo não se pode dizer do acesso a instituições privadas que, além de apresentar forte hiato socioeconômico, permite que estudantes nos estratos mais altos de renda tenham elevadas chance de acessá-lo ainda que apresentem os piores desempenhos. Concluímos que a estratificação horizontal da educação brasileira estrutura a ocorrência de vantagens duplas para estudantes de origem privilegiada: vantagens compensatórias no acesso ao setor privado e vantagens cumulativas no acesso ao setor público, em razão, respectivamente, de seus privilégios de origem e de suas probabilidades de obter maiores notas.

Published: May 2023

In this work, characterisation of urban wastewater from Fez City, Morocco, consisting mainly of a mixture of industrial and urban discharges, and its treatment using the coagulation–flocculation (C-F) process were conducted. Three coagulants were used: lime (Ca(OH)2), ferric chloride (FeCl3) and alum (Al2(SO4)3). Ferric chloride achieved the highest reductions in turbidity, chemical oxygen demand (COD) and colour. Then, the Box–Behnken design was applied to optimise the amounts of the coagulant and flocculant and pH. The maximum response values were 78, 98 and 99% for COD, colour and turbidity, respectively, under the following optimal operating conditions: [FeCl3] = 720 mg/l, [flocculant] = 150 mg/l and pH = 7. The operational cost of C-F implemented in this study was estimated at US$0.52/m3, proving that it could be a competitive and cost-effective process for the treatment of wastewater. These results will contribute to the existing literature and would be valuable for scaling up the C-F process.
Torsional installation and vertical tensile capacity of helical piles in clay
Authors: Ullah Shah Neyamat , O'Loughlin Conleth , Hu Yuxia , Hou Lee Fook
Published: May 2023

Helical piles are being increasingly considered for offshore applications as they avoid the acoustic emissions associated with pile driving, and they provide additional capacity relative to a driven pile. In this paper, the installation and tensile capacity of helical piles is considered through a combination of centrifuge experiments and large-deformation finite-element analyses within a coupled Eulerian–Lagrangian framework. The experiments provide a basis for validating the numerical simulations, but also quantify the expected installation torque and undrained tensile capacity, including the variation with time after installation. The numerical simulations extend the parameter space investigated experimentally, considering the number of helices, their spacing and pitch, in addition to the ratio of pile shaft to helix diameter and the profile of undrained shear strength. Mechanisms revealed through the numerical simulations are reflected in a new analytical model for calculating undrained tensile capacity, which is seen to agree reasonably well with the numerically and experimentally determined capacities.
Responses of live-bed scour at instream structures to fluvial bedform migration
Authors: Yang Yifan , Wang Lu , Melville Bruce W. , Shamseldin Asaad Y. , Macky Graham H.
Published: May 2023

Migrating bedforms in alluvial rivers can exacerbate scour damage at instream structures and lead to structural failure. This study investigates the interaction between scour at instream structures and bedform migration. Both two-dimensional (submerged weirs) and three-dimensional (uniform and complex piers) structures are considered. Two components constitute live-bed scour depth: the dynamic scour amplification Δds caused by bedforms and the local flow-induced baseline scour depth dsNB. Results show that, for 2D structures, the baseline scour depth is negligible, while the live-bed scour is mainly caused by approaching bedforms. The dynamic scour amplification normalised by the approaching bedform height (Δds/Hb) decreases with the decrease of upstream angle and varies between 0.5 and 2. For uniform 3D structures, the local flow could cause a considerable baseline scour depth, and Δds/Hb varies between 0.25 and 0.5 and decreases with the increase in the flow capacity to damp bedforms. For complex 3D structures, flow pressurisation beneath the pile-cap magnifies Δds/Hb to near 1. In general, Δds/Hb is inversely correlated with ds_NB/y0, where y0 is flow depth. New equations are proposed for estimating the dynamic scour amplification at various instream structures with design rules recommended.

Consumption: Ethical Perspective of Islamic Economics
Authors: Rohmana Yana
Published: May 2023

AbstractPurpose - The problem of consumption in the framework of Islamic economics is how to fulfill needs so that satisfaction is achieved, full of ethics by adding social preferences and benefits, and hoping to achieve the pleasure of Allah SWT.Methodology - Such consumer behavior should be based on Islamic moral consumption ethics with the guidelines of the Qur'an and Sunnah. The principles of consumption within the framework of Islamic ethics, namely (i) the principle of permissibility and generosity; (ii) Responsibility and Simplicity Principles; (iii) Principles of Balance and Fairness; and (iv) Priority and Morality Principles. Findings - All consumption ethics are aimed at achieving falah, which is a noble and prosperous life in this world and the hereafter with the fulfillment of the needs of human life in a balanced way. The fulfillment of community needs will have an impact called mashlahah (individual and social welfare) in the hope of achieving the pleasure of Allah SWT. So it is fitting that the consumption of a Muslim is as a means of help to worship Allah SWT. So its consumption must conform to the hierarchy of essential (darūriyyāt), complementary (hājiyyāt) and embellished (taḥsīniyyāt) needs. Islam forbids consumers to take extreme actions (up to the upper limit) in the form of excessive consumption (israf) or wasteful consumption (tabdhir), and also avoid stingy consumption. The prohibition set is not to limit mankind, but to ensure the benefits are maintained and harm is avoided in consumption. Keywords: Consumption, Ethics, Islam, Falah.

Introduction: Stress among students is a growing problem. As emotional stress increases, the limbic structures and hypothalamus are stimulated, activating the gamma efferent system, which ultimately leads to an increase in muscle tone or additional muscle activity that can become repetitive behaviors such as bruxism. The aim of the study was to investigate the stress level that students are exposed to, to determine the difference between students in terms of gender, faculty, and year of study, and to evaluate the possible relationship between stress level and self-reported bruxism in college students during the pandemic COVID-19.
Methods: In April 2022, a cross-sectional study was conducted on a sample of students from the Faculty of Dentistry and the Faculty of Pharmacy at the University of Sarajevo (BiH). The students answered a questionnaire consisting of two parts: The first part contained questions on basic personal data and data on self-reported bruxism and the second part contained questions on the perceived stress scale (PSS).
Results: The study included 756 students from both faculties. Analysis of stress levels among students revealed higher stress levels. Female students were more likely to be under stress than male respondents. Students in the Faculty of Pharmacy were more likely to be stressed than students in the Faculty of Dentistry. At the Faculty of Pharmacy, there was no difference in stress levels between the different years of study, while at the Faculty of Dentistry, the individual score for PSS was highest among 1st-year students. A high prevalence (46.8%) of self-reported bruxism was found among students in both faculties.
Conclusion: A slight positive correlation between self-reported bruxism and stress suggests that it is important to implement stress management strategies during academic education and to prevent bruxism and its consequences.

Introduction. The pandemic of a novel coronavirus infection has demonstrated the importance of assessing the ADAMTS-13/vWF axis in patients with COVID-19, because a decline in this ratio mirrors disease severity. However very few data in the global literature on crosstalk and ADAMTS-13/vWF levels in pregnant women remaining very contradictory are available. Taking into consideration an impact of the ADAMTS-13/vWF axis on prevalence of thrombosis and disorders in the hemostasis system, investigation of this issue is highly demanded.

Aim: to assess the functioning of the ADAMTS-13/vWF axis during physiological pregnancy.

Materials and Methods. A controlled non-randomized study was conducted: main group included 44 women with physiologically occurring pregnancies at I, II and III trimesters; the control group consisted of 45 healthy non-pregnant women. The plasma level of ADAMTS-13 inhibitor (ADAMTS-13:i), ADAMTS-13 antigen (ADAMTS-13:Ag), vWF antigen (vWF:Ag), and ADAMTS-13 activity (ADAMTS-13:Ac) as well as relevant ratio (ADAMTS-13:Ac/vWF:Ag) were measured.

Results. It was shown that in parallel with increasing gestational age, significant changes occurred in the ADAMTS-13:Ac/vWF:Ag ratio. In main group, patients at II trimester were found to have level of ADAMTS-13:Ac/vWF:Ag 0.359 ± 0.121, in III trimester –0.253 ± 0.741, which significantly differed (p < 0.01) compared to control group with non-pregnant women (1,134 ± 0,308).

Conclusion. Our study provides new insights into the functioning of the ADAMTS-13:/vWF axis in women with physiologically occurring pregnancy at I, II and III trimesters. Decline in ADAMTS-13:Ac was demonstrated along with increasing vWF:Ag level observed in parallel with increasing gestational age. Apparently, the progressive decrease of ADAMTS-13 concentration during pregnancy is associated with its increased consumption due to high vWF level. However, due to the small single-center patient cohort, further studies with larger-scale studies are needed.
The study of platelet microparticles and P-selectin expression in patients with the peripheral arterial diseases
Authors: Ermakov Aleksei I. , Gaikovaya Larisa B. , Sirotkina Olga V. , Vavilova Tatiana V.
Published: May 2023

BACKGROUND: High platelet reactivity leads to the progression of atherosclerosis and its complications. Activated platelets adhere to the site of endothelium damage on the vessel wall and initiate the formation of an arterial thrombus, followed by acute ischemia of the organ. Biochemical and cellular marker such as platelet microvesicles and P-selectin can be analyzed using flow cytometry, which is based on a specific antigen-antibody interaction. Patients with peripheral arterial disease are at significantly greater risk of cardiovascular and cerebrovascular complications than individuals of the same age and sex. The use of antiplatelet agents is an important part of pathogenetic therapy and prevention of cardiovascular diseases and their complications.
AIM: This study was to evaluate the level of platelet microparticles and P-selectin expression in patients with peripheral arterial disease receiving antiplatelet therapy.
MATERIALS AND METHODS: The study included 49 people, which included three study groups: patients with obliterating disease of the arteries of the lower extremities (n = 14) on the background of long-term use (more than 14 days) of double (75 mg clopidogrel and 100 mg Acetylsalicylic acid) antiplatelet therapy, patients with COVID-19 (n = 15), who made up the positive control group in the determination of microparticles of platelet origin, and healthy volunteers (n = 20) without signs of acute respiratory disease, without a history of cardiovascular and thromboembolic episodes, not taking antiplatelet drugs. The functional activity of platelets was assessed by two methods: using light aggregometry and analysis of P-selectin expression on platelet surface by flow cytometry. The number of platelets microparticles in blood plasma was also determined using flow cytometry.
RESULTS: A significant decrease in platelet aggregation was found in patients with peripheral arterial disease taking antiplatelet agents, compared with controls by used light aggregometry. Similar changes were obtained when analyzing the expression of P-selectin on platelets. A higher percentage of platelets microparticles with the CD9+CD41+ phenotype was found in patients with severe inflammation compared with peripheral arterial disease patients treated with antiplatelet agents and compared with the healthy controls.
CONCLUSIONS: Thus, our study reflects the consistency of the results of three different laboratory tests in assessing the platelets reactivity in patients with the peripheral arterial diseases taking antiplatelet drugs.

The scaling of anatomical, physiological, and life history traits with organisms' body size is of great ecological significance, and an important scaling relationship is that between body size and metabolic rate. There have been many hypotheses as to why this relationship, resembling a line with a slope of 0.75, takes this shape. These include surface area, resource supply, resource demand, and life history-related theories, and some of them assert a universal slope for this scaling relationship. Despite this, variation has been observed in metabolic scaling relationships both within and among taxa of organisms, and ecological factors have significant influence on metabolic scaling. We show clade-specific variation within birds, with variation occurring in both the slope and intercept of linear models. Migratory tendency and diet also affect metabolic rate. We also compare the birds to the mammals in slope-intercept space, showing systematic diversity in scaling. We next demonstrate a similar clade-specific diversity in metabolic scaling within the squamate reptiles, which exhibit a wider array of slopes and intercepts than do the endotherms. We found that temperature sensitivity of metabolism varies among clades. Foraging strategy and habitat have significant bearing on the intercepts of these regressions. Since foraging is strongly tied with metabolism and energetic strategy, we then compare aspects of locomotor morphology (humeral midshaft) in lizards of different foraging styles (e.g., presumably different resting and active metabolisms). The less active ambush predators have more robust humeri than do the widely foraging predators, but the pattern is complicated.
CHTF18 Safeguards the Quantity and Quality of the Ovarian Reserve and Mediates Meiotic Cohesion

As women age, a decline in oocyte quality due to aneuploidy leads to infertility, miscarriage, and congenital anomalies. Age-related aneuploidy can arise from meiotic errors and loss of chromosome cohesion, the defects of which are incompletely understood. In these studies, we report that CHTF18, a subunit of the Replication Factor C-Like complex, ensures the quality and quantity of the oocyte pool and mediates female meiotic cohesion via cohesins. Chtf18-/- female mice display age-dependent subfertility and ovaries that contain significantly fewer follicles than wild-type females. Consistent with age-dependent subfertility, Chtf18-/- follicle pools are nearly depleted by six months of age, and female neonates are born with fewer follicles than wild-type controls. In Chtf18-/- oocytes, homologous chromosomes undergo synapsis but separate prematurely during prophase I. Meiotic recombination is also defective with persistent DNA double-strand breaks and decreased crossovers. Consequently, Chtf18-/- oocytes are poor quality and fail to progress or are aneuploid at metaphase II. Interestingly, centromeric cohesion is also weakened in Chtf18-/- oocytes at metaphase II. Given the phenotypes of premature homolog disjunction and weakened centromeric cohesion in Chtf18-/-oocytes, we investigated a role for CHTF18 in meiotic cohesion. We revealed that chromosome-associated REC8, a meiotic cohesin, is decreased in prophase I and metaphase I oocytes, suggesting that CHTF18 aids in stabilizing and maintaining REC8 on chromatin during meiosis I. Because cohesins function via regulator proteins, we assessed NIPBL, PDS5B, and WAPL, involved in cohesin loading, maintenance, and release. In Chtf18-/- oocytes PDS5B was significantly decreased and WAPL was mislocalized during prophase I. These results suggest that CHTF18 interacts with PDS5B and/or WAPL, which may facilitate REC8 association with chromatin during meiosis. CHTF18 is known to play a role in cohesion establishment during mitosis. Therefore, we postulate a crucial role for CHTF18 in cohesion establishment and maintenance during female meiosis. By defining the role of CHTF18 in female meiotic cohesion, we aim to better understand how the age-related decline in oocyte quality arises, ultimately leading to improved infertility treatments in women.

Geçiş dönemlerinin sonuncusu olarak kabul edilen ölüm, tüm insanlık için kaçınılmaz bir sondur. Ölümün vermiş olduğu korku, toplumlarda ölümle ilgili çeşitli inanç ve ritüellerin ortaya çıkmasına sebep olmuştur. Afrika yerel inançlarına göre yaşam süresi, ölüm ile sona ermez. Aksine yaşam başka bir alemde devam eder. Diğer taraftan ölüm, korkulan bir olay olsa da görünen ve görünmeyen varlıklar arasındaki iletişimin başlangıcı olarak kabul edilir. Hayat ve ölüm kavramları birbiri ile ilişkili hatta birbirini tamamlar biçimdedir. Afrika yerel inançlarının büyük bir çoğunluğu ölümü yaşam döngüsünün bir parçası olarak kabul etse de ölümün doğaüstü güçlerle bir bağlantısı olduğu üzerinde hemfikirdir. Afrika yerel inançlarında cenaze törenlerinin kurallara uygun bir şekilde yapılmasına özen gösterilir. Afrika topluluklarındaki cenaze törenlerinde farklı uygulamalar olmakla beraber birbirine benzer adetlerin de görüldüğü tespit edilmiştir. Bu çalışmada Afrika’daki birçok topluluğun ölüm ile ilgili inanç ve ritüelleri incelenecektir. Literatür taraması ile elde edilen makale verileri, Dinler Tarihinin deskriptif metodu kullanılarak yazıya geçirilmiştir.
THE IMPORTANCE OF REGIONAL ORGANIZATIONS ESTABLISHED IN EURASIA FOR TURKEY: SHANGHAI COOPERATION ORGANIZATION
Authors: Aksu Zehra
Published: May 2023

In this study, the SCO-Turkey relations are analyzed; An answer has been sought to what are the reasons that make the SCO important for Turkey. Founded in 1996 with the Shanghai Five, the SCO was officially established on June 15, 2001. The organization has nine full members, three observer members, and nine dialogue partners. Turkey is one of the important countries with “dialogue partner status” among SCO partners. Turkey, which joined the organization as a dialogue partner at the 2012 Beijing Summit, wants to improve its relations with Eurasian countries and strengthen its position vis-à-vis Western countries with its model country mission. The gradual shift of the world's economic and financial centre to the East and the search for alternatives to the EU membership make the SCO important for Turkey. Turkey's problem of trust in Western states, whose EU membership process is in a deadlock, leads Turkey to establish relations with the SCO and to follow a proactive foreign policy. It is expected that Turkey will carry its dialogue partnership status at the SCO to observer state status in the coming years to remind that Turkey has a strategic value against Western states. Full membership status is not expected due to the reality that Turkey cannot give up its cooperation with Western institutions and organizations for many years.
