Effects of Land Use on Millipede Communities (Subphyllum Myriapoda, Class Diplopoda): A Review
Authors: Tudose Cezara , Rîșnoveanu Geta
Published: March 2024

Millipedes are soil macrodetritivores with considerable roles in decomposing organic matter and recycling nutrients. This paper aims to identify the effects of land use on millipedes based on a literature review. Land use changes impact species distribution, diversity, and behavior with consequences for litter decomposition and soil quality. Surrounding landscapes influence the millipedes’ community structure. The effects of land use under different ecological contexts and in wetlands and woody riparian zones constitute essential gaps in knowledge.

Published: March 2024

Background: Bullying occurs more frequently which is detrimental to adolescent development.
 
Aim: Examining the relationship between demo data, parental interactions, and parenting practices as potential contributors to adolescent bullying behavior.
 
Methods: A cross-sectional study methodology was used. The research population is teenagers who attend junior and senior high schools in Surabaya. Based on re-sampling for research, the research sample consisted of 1855 teenagers. One month duration. bullying behavior is the dependent variable, while demographic traits, parental interactions, and parenting philosophy are the independent variables. Teenagers completed the questionnaire using the Google form and questionnaire sheet, which is the method used to collect data. The chi-square test for adolescent  traits  and  Spearman's  rank  correlation  of =  0.05  were  used  in  the statistical analysis.
 
Results: Bullying behavior was found to be correlated with adolescent characteristics, especially age (P=0.003). Only  permissive parenting style had a positive correlation  (p=0.036,  r=0.094)  with  intimidation,  while  authoritarian  and  permissive parenting styles had a negative correlation (p=0.000, r=0.131) with intimidation.
 
Conclusion: Teenagers are involved in bullying behavior, both as victims and perpetrators. Be young. There is a high probability that parenting philosophies that are too strict or too permissive will result in bullying behavior. To reduce the possibility of bullying among adolescents, parents are expected to apply authoritative parenting.

Authors: Kuşcu Savaş , Çaktü Güler Kıvılcım
Published: March 2024

Buğday özellikle insanların beslenmesinde büyük rol üstlenmiştir. Yetiştirilmesi son derece zahmetsiz olsada yapılan araştırmalar, iklim değişikliğinden buğdayında olumsuz etkileneceğini ortaya koymuştur. Anadolu’da buğday ekili alanlarda verim ve kaliteyi arttırmak için gübreleme yapılmaktadır. Gübreleme yapılırken uygulanan miktara, uygulama zamanına ve gübre türüne dikkat edilmesi gerekir. Kontrolsüz yapılan gübreleme toprağa ve çevreye zarar vermektedir. Toprağı verimsiz hale getirirken, atmosferede sera gazı salınımına neden olacaktır. Bu durum ise buğday üretiminde ki karbon ayak izinin artmasına neden olacaktır. Yaptığımız bu çalışma da buğday üretimi yapılırken çiftçiler tarafından kullanılan gübrelerin, kullanım miktarına bağlı olarak ürettiği karbon ayak izini hesapladık.
Tuz Stresinin Hafifletilmesinde L-Argininin Zea mays’da Antioksidan Enzim Aktivitesi Üzerine Etkisi
Authors: Arslan Yüksel Esra
Published: March 2024

Arjinin, bitkilerde stres metabolizmasında yer alan çeşitli metabolitlerin öncülüğünü yapan bir aminoasit olmasının yanı sıra, bitkilerin çevresel streslere yanıtını modüle edebilen bir sinyal molekülüdür. Tuzluluk stresi, özellikle mısır (Zea mays) yetiştiriciliğinde, mahsul verimliliğini artırma açısından önemli bir zorluk oluşturmaktadır. Bu çalışma, L-argininin (L-arg) lipid peroksidasyonunu, bazı antioksidan enzim aktivitelerini ve bu enzimlerin gen ifade seviyelerini modüle ederek tuz stresinin neden olduğu oksidatif hasarı hafifletmedeki potansiyel rolünü araştırmaktadır. Bulgularımız, 200 mM tuz stresi uygulamasında H2O2 ve MDA seviyelerinin arttığını, ancak 1,5 ve 3 mM L-arg uygulamalarının bu seviyeleri azalttığını göstermektedir. Ayrıca çalışmamızda, süperoksit dismutaz (SOD), peroksidaz (POD) ve askorbat peroksidaz (APX) aktiviteleri ile ZmSOD, ZmPOD ve ZmAPX gen ifade seviyelerinin tuz stresi altında giderek arttığı, ancak L-arg’ın bu parametreleri arttırmada daha etkili olduğu belirlenmiştir. En yüksek artışlar SOD enzim aktivitesinde ve ZmSOD gen ifadesinde gözlemlenmiştir. Bu araştırma, tuz stresinde bazı moleküler ve biyokimyasal yanıtların anlaşılmasını derinleştirerek, L-arg uygulamasının bitkilerin çevresel zorluklara karşı direncini artırmada kritik bilgiler sunabileceği önemli bir literatür kaynağıdır.

Authors: Çakmakcı Selma , Sarı Neriman , Sönmez Çiğdem , Ergürhan İlhan İnci
Published: March 2024

Background. We assessed the relationship between sepsis occurrence and the serum levels of angiopoietin (Ang-1, Ang-2), vascular endothelial growth factor (VEGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) in pediatric patients with cancer-related febrile neutropenia.
Methods. Fifty-two children with malignant tumors who experienced 86 episodes of febrile neutropenia (FN) were examined between June 2016 and June 2018. Each FN episode was considered a separate event and the total number of FNs were recorded (86 FN episodes = FN group). The control group consisted of 21 healthy children. Ang-1, Ang-2, VEGF-A and sFlt-1 were measured at the baseline and 48th hour of each FN episode –alongside routine characterization of inflammation (C-reactive protein; white blood cell and absolute neutrophil count).
Results. Among the episodes, 29 (34.5%) developed sepsis while 57 were classified as non-complicated FN. The baseline values of patients and controls were significantly different for Ang-1, Ang-2, VEGF and sFlt-1 values (all, p < 0.05). In the subgroup with sepsis, Ang-2 values were higher than in the subgroup without sepsis (p = 0.017). In predicting sepsis, Ang-2 had 60.7% sensitivity and 66.7% specificity at the 74.6 cut-off value (AUC: 0.662 [95%CI: 0.541 – 0.783], p = 0.022), Ang-2 / Ang-1 ratio had 65.5% sensitivity and 60.0% specificity at the 0.405 cut-off value (AUC: 0.633 [95%CI: 0.513 – 0.753], p = 0.046).
Conclusions. Our results reveal that Ang-2 and Ang-2/Ang-1 were higher in the sepsis group and Ang-2 might be a biomarker to indicate the risk of sepsis in patients with FN and/or cancer.

Published: March 2024

Background. Relapses or new-onset IgA nephropathy (IgAN) have been documented in patients after vaccination against SARS-CoV-2; however, only one adult patient has been reported in whom pre-existing IgAN worsened during coronavirus disease 2019 (COVID-19).
Case. We present the first pediatric case with biopsy-proven IgAN and genetically confirmed Alport syndrome, who developed end-stage kidney disease after an exacerbation of IgAN associated with COVID-19. The patient’s basal serum creatinine was 0.7-0.9 mg/dL before infection. He had not been vaccinated against COVID-19. He was admitted to the hospital with edema, hypertension, an elevated serum creatinine of 4.7 mg/dL, and massive proteinuria. Three months before admission, he had been admitted to another hospital with COVID -19 and an elevated serum creatinine (1.9 mg/dL), but no biopsy had been performed at that time. The kidney biopsy revealed IgAN with 50% fibrocellular crescents with sclerosed glomeruli, tubular atrophy, and interstitial fibrosis. His serum creatinine did not decrease even after five administrations of pulse steroids, and hemodialysis was initiated.
Conclusion. In conclusion, COVID -19 may pose a high risk for exacerbation of pre-existing glomerular disease. It is therefore necessary to closely monitor the kidney function of patients with underlying glomerulonephritis during and after COVID-19 and consider an early biopsy if serum creatinine does not return to baseline levels. In addition, this case report highlights the clinical importance of the co-occurence of IgAN and Alport syndrome.

Published: March 2024

Background. Gastrointestinal system disorders are known to be prevalent among children with autism spectrum disorder (ASD). Some ASD-associated comorbidities are abdominal pain, constipation, diarrhea, gastroesophageal reflux, sleep disturbances, epilepsy, and psychiatric problems. Nonetheless, there is still limited information about the presence of functional GI disorders (FGIDs) among children with ASD, especially in Türkiye. Using the Rome criteria, we aimed to investigate FGIDs in children with ASD.
Methods. The sample of the study consisted of 68 children aged 4-10 years, diagnosed with ASD according to the DSM-5 diagnostic criteria and had scores greater than 30 on the Childhood Autism Rating Scale (CARS-2) and an age-sex matched control group (n=78). The Rome III criteria were used to evaluate FGIDs.
Results. The frequency of FGIDs in the ASD group was higher (76.5%) compared to the control group (p<0.001). Compared to the control group, abdominal migraine frequency increased 10 times (p=0.012), functional constipation 7 times (p<0.001), and fecal incontinence 6 times (p<0.001) in the ASD group. Stool retention was not present in most children in the ASD group who were found to have fecal incontinence.
Conclusion. In this study, the most common FGIDs in the ASD group were abdominal migraine, functional constipation, and non-retentive fecal incontinence. The finding that most children with ASD who had fecal incontinence did not show stool retention implicated social, psychological, and behavioral factors as the causes of incontinence. Raising awareness of healthcare professionals about the frequency of FGIDs in children with ASD will improve many areas in the daily lives of these children.
Camptodactyly-arthropathy-coxa vara-pericarditis syndrome and an unusual association with mitral stenosis
Authors: Şimşekli Duygu , Ayabakan Canan , Oktay Ayla , Arnaz Ahmet , Mahmudov Vusal , Yalçınbaş Yusuf Kenan
Published: March 2024

Background. Campotodactyly-artrhropathy-coxa vara-pericarditis (CACP) syndrome is a very rare autosomal recessive genetic disorder. It is characterized by flexion contracture of the fifth finger (camptodactyly); non-inflammatory arthropathy; decreased angle between the shaft and the head of the femur (coxa vara) and pericarditis. Its association with mitral stenosis has not yet been reported. Hereby we report this unique association with CACP syndrome.
Case. An eleven-year-old girl presented with non-productive cough, dyspnea, and orthopnea. She was diagnosed CACP syndrome at the age of seven and a biallelic frameshift mutation in the PRG4 gene was determined. The physical examination revealed pectus excavatum, camptodactyly, genu valgum, tachypnea and orthopnea. The functional capacity was NYHA III-IV. She had 2/6 soft pansystolic murmur at 4th left intercostal space and a rumbling diastolic murmur at apex. Echocardiography revealed an enlarged left atrium, severe stenotic mitral valve with a mean diastolic transmitral gradient of 22.5 mmHg, mild mitral regurgitation and mild apical pericardial effusion. The patient had mitral comissurotomy and partial pericardiectomy operation. Her post-operative transmitral gradient decreased to 6.9 mmHg and the pulmonary pressure was 30 mmHg. Her functional capacity increased to NYHA I-II.
Conclusions. The main defect is the proteoglycan 4 protein which acts like a lubricant in articular and visceral surfaces. Therefore, the leading clinical feature is arthropathy. Cardiac involvement other than clinically mild pericarditis is not usually expected. Three types of proteoglycans (decorin, biglycan, and versican) are present in the mitral valve. This could be the reason of mitral valve involvement in rare cases as like ours. It is important that these patients undergo echocardiographic examination regularly.

Background. At the onset of the pandemic, we conducted a study on adolescents with eating disorders (EDs) and found no deterioration in ED symptoms. The objective of this subsequent study was to conduct a follow-up evaluation of the same cohort and investigate the consequences of the prolonged pandemic.
Methods. This longitudinal study was conducted one year after the first study between May 2021 and June 2021 with 37 adolescents aged 12-18 years (pre-existing EDs). The reassessment included an evaluation of sociodemographic and clinical characteristics, the impact of pandemic-related restrictions on ED behaviors, well-being, and quality of life. All the participants underwent a re-administration of the ED examination questionnaire (EDE-Q), Beck Depression Inventory, the State Anxiety Inventory for Children, and the Maudsley Obsessive Compulsive Inventory.
Results. No significant difference was observed in the EDE-Q scores or the ED examination questionnaire scores between the initial (T1) and subsequent (T2) study. The ED-related quality of life was seen to have slightly improved in the later stage. While depression (T1: 18, T2: 15, p=0.883) and obsession scores (T1: 11, T2: 14, p: 0.536) showed no disparity between the studies, anxiety scores (T1: 38, T2: 43, p:0.011) exhibited a significant increase.
Conclusions. Consistent with the early phase, no exacerbation of ED symptoms in adolescents was observed during the later stages of the pandemic. Close clinical monitoring during the pandemic might have been protective against the deteriorating effects of the pandemic. During social isolation, it is important to monitor adolescents with EDs continously for depression and anxiety.

Low-Thrust Resonance Gravity-Assist Trajectory Design for Lunar Missions
Authors: Lee Jinsung , Ahn Jaemyung
Published: March 2024

This paper introduces a procedure to optimize a low-thrust gravity-assist trajectory to the Earth–moon L1 periodic orbit utilizing the resonance-orbital structure as a guideline. The Earth–moon circular restricted three-body problem formulation is used to describe the problem. The proposed procedure determines the gravity-assist geometry and then finds the gravity-assist linking based on the multiple-point boundary value problem. The gravity-assist geometry determination step designs the periapsis rotation angle by solving a gradient descent optimization problem, yielding trajectories that break the symmetry of the resonance orbits. The multiple-point boundary-value problem seeks to solve a minimum-fuel problem linking two intermediate resonance-like orbits with rotated periapses. The first step of the optimal control problem establishes and solves a relatively easy two-point boundary problem approximating the original problem. The solution is used as the initial guess for the more complex multiple-point boundary value problem. The low-thrust resonance gravity-assist trajectory is compared to the trajectories designed based on traditional approaches involving low-thrust propulsion, demonstrating its validity and efficiency.
Aerodynamic Performance of a Finite-Span Wing in a Time-Varying Freestream
Authors: Gloutak Dasha , Jansen Kenneth E. , Farnsworth John A.
Published: March 2024

The current study analyzes the dynamic response of a NACA 0015 finite-span wing to a time-varying freestream in an unsteady wind tunnel at a mean Reynolds number of [Formula: see text]. The aerodynamic response of the wing can be categorized based on the angle of attack and the degree of flow separation on the suction side of the wing. When the suction side is dominated by separated flow, either at low angles of attack with long laminar separation bubbles or at high, poststall, angles of attack, the lift is enhanced by the favorable pressure gradient during freestream acceleration and decremented by the adverse pressure gradient during freestream deceleration. In these cases, the sectional lift coefficient is shown to oscillate by as much as [Formula: see text] due to the unsteady pressure gradient. Comparatively, regions of attached flow on the wing surface remain largely unaffected by the time-varying conditions, regardless of the reduced frequency. Discrepancies between the measured lift and the estimated response from Isaacs’s theory demonstrate that the coupling between the viscous flow separation and the unsteady conditions dominates the unsteady aerodynamic response.
Influence of Complex Geometries on Damage Tolerance of Porous Carbon Fiber Network
Authors: Quammen R. Nicholaus , Rottmann Paul F.
Published: March 2024

Porous materials exhibit a variety of attractive functional properties for aerospace applications, such as low density and low thermal conductivity. However, they must also be mechanically robust and damage tolerant to fully realize their potential. Currently, it is costly and time-consuming for testing under service conditions, therefore, computational models are a good path forward. Due to the inherent microstructural stochasticity of these structures, however, their behavior is difficult to effectively model without detailed experimental studies for validation and benchmarking. To that end this study investigates the mechanical properties of a porous carbon fiber network and ties together the global macroscopic observations to the local mesoscale behaviors dictated by individual fibers and fiber junctions. Strain localization was observed using digital image correlation (DIC) and tied to features within the macroscopic stress–strain plots. Work to quantify the impact of the addition of complex geometries (e.g., cracks and through-holes) on mechanical reliability was conducted. The defects resulted in distinct macroscale mechanical characteristics and mesoscale deformation behaviors, depending on defect type and loading orientation. These results provide broad experimental data to inform and validate modeling approaches to accurately predict and tailor the reliability of porous parts under service conditions.

Published: March 2024

A case report of a 32-year-old female patient without any traditional risk factors presented with angina to our hospital within 6 h. Her electrocardiogram (ECG) showed extensive anterior wall -ST elevation myocardial infarction (MI). She was treated with thrombolytic therapy in the form of tenecteplase and was given standard treatment for acute coronary syndrome (ACS). Her history revealed three recurrent pregnancy losses and a history of preeclampsia. Echocardiography showed regional wall motion abnormalities of the mid, distal, apex, and anterior wall with severe left ventricular systolic dysfunction. Routine blood investigations showed elevated total leukocyte count with neutrophilic predominance. With a history of recurrent pregnancy loss, she was investigated for anti-phospholipid anti-phospholipid antibody syndrome (APS) and was found to have positive lupus anticoagulant 1. She underwent coronary angiography (CAG) which showed a left main shaft 40% stenosis with an ulcerative lesion containing thrombus in the ostioproximal to mid-left anterior descending artery (LAD), other coronary arteries were normal. She was managed conservatively with glycoprotein IIb/IIIa inhibitor (Tirofiban) and switched to oral anticoagulation with Vitamin K antagonist (VKA-Acenocoumarin) along with dual-antiplatelet therapy.
