Authors: Aziis Dimas Miftahul , Wirasatriya Anindya , Setiyono Heryoso
Published: February 2025

Laut Sawu merupakan salah satu wilayah perairan di Indonesia yang memiliki tingkat kesuburan dan potensi akan sumber daya lautnya. Laut Sawu termasuk peraian yang terpengaruh dari ENSO. Fenomena ENSO dapat mempengaruhi distribusi Suhu Permukaan Laut, curah hujan di Laut Sawu. Penelitian mengenai pengaruh ENSO terhadap Suhu Permukaan Laut dan curah hujan telah banyak dilakukan, namun tidak spesifik pengaruh El Nino kuat tahun 2023 di Laut Sawu masih sedikit. Penelitian ini dilakukan untuk mengetahui pengaruh dan mekanisme El Nino terhadap Suhu Permukaan Laut dan curah hujan. Data yang digunakan dalam penelitian ini terdiri dari SPL, curah hujan dan Angin yang bersumber dari OSTIA, CMORPH, CCMP. Pengolahan data pada penelitian ini menggunakan Bahasa pemrograman Interactive Data Laguage (IDL) dengan menampilkan data klimatologi, timeseries dan anomali. Hasil analisis menunjukkan bahwa nilai SPL, angin, dan curah hujan di Laut Sawu mengalami fluktuasi saat El Nino terjadi pada tahun 2023. Kondisi SPL mengalami peningkatan selama periode El Niño, dimana SPL memiliki nilai 29°C di bulan Desember pada musim barat. Sedangkan curah hujan mengalami penurunan selama El Niño dengan nilai 3 mm. Musim timur kondisi SPL di Laut Sawu mengalami peningkatan dengan nilai 27,4°C. Sedangkan curah hujan memiliki nilai yang sama dengan klimatologi. Ketika terjadinya fenomena El Niño 2023 angin memiliki kecepatan yang kuat. Pada periode El Niño 2023 yang terjadi di akhir tahun SPL meningkat secara signifikan di musim barat pada bulan Desember. Namun berkebalikan dengan penurunan intensitas curah hujan di Laut Sawu. Hal ini dikarenakan pengaruh dari pola angin yang berasal dari Benua Australia yang membawa udara kering dan mengakibatkan rendahnya curah hujan di Laut Sawu.

Published: February 2025

Pantai Dadap merupakan salah satu wilayah di Kecamatan Juntinyuat, Kabupaten Indramayu yang mengalami kemunduran garis pantai yang menyebabkan kerusakan properti serta hilangnya lahan warga. Penanggulanan masalah ini maka Balai Besar Wilayah Sungai (BBWS) Cimanuk Cisanggarung membangun bangunan pengaman pantai berupa breakwater. Tujuan dari penelitian ini adalah untuk untuk mengetahui pengaruh pembangunan breakwater terhadap perubahan garis pantai di Pantai Dadap Indramayu. Periode waktu yaitu tahun 2020 hingga 2024 dari hasil interpretasi citra satelit Google Earth. Data yang digunakan yaitu data kelerengan pantai, ukuran butir sedimen, dan citra Google Earth. Pengolahan data sedimen dilakukan menggunakan metode buchanan. Data citra Google Earth di analisis untuk mendapatkan perubahan garis pantai tahun 2020 dan 2024 dan pengambilan garis pantai lapangan untuk tahun 2024. Hasil dari penelitian ini menunjukan pada tahun 2020 – 2022, Pantai Dadap lebih banyak terjadi abrasi dibandingkan terjadinya akresi. Luasan abrasi yang terjadi seluas 1,37 hektar dan luasan akresi seluas 0,52 hektar. Tahun 2022 – 2024, dinamika garis pantai cenderung stabil dengan terjadinya abrasi dan akresi dalam luasan yang lebih kecil. Luasan abrasi yang terjadi seluas 0,36 hektar dan luasan akresi seluas 0,29 hektar. Hal ini dikarenakan adanya penambahan panjang breakwater sehingga garis pantai lebih terlindungi dari terjangan arus dan gelombang secara langsung.

Published: February 2025

Understanding the management of the rice root-knot nematode Meloidogyne graminicola is an essential component of rice. The study aimed to investigate the extent to which the nematicidal actions of 2,1,3- benzothiadiazole, fluopyram, fluensulfone and carbofuran against the rice root-knot nematode, M. graminicola could be determined using in vitro, in vivo and in silico studies. Among the tested compounds, fluopyram demonstrated the highest juvenile mortality rate (91.26%) and binding affinity (-8.3 kcal/mol) to the seven selected target proteins of M. graminicola, driven by significant hydrophobic, alkyl and H-bonding interactions. Comparative binding affinities were recorded for fluensulfone (-6.9 kcal/mol), carbofuran (-6.4 kcal/mol), 2,1,3-benzothiadiazole (-5.0 kcal/mol) and untreated control. These findings have significant implications for agricultural practices, particularly in developing integrated pest management (IPM) strategies. The high efficacy of fluopyram, as evidenced by its biochemical ligand-target protein interactions, suggests its potential as a key component in IPM programs. By integrating nematicidal treatments with other control measures such as crop rotation, resistant rice varieties and biological control agents, sustainable management of M. graminicola can be achieved by reducing dependency on chemical pesticides. Furthermore, this study underscores the importance of using molecular insights to design targeted pest management solutions, paving the way for environmentally responsible and economically viable approaches to nematode control in rice cultivation.

Authors: Wendl Thomas , Wendl Brigitte , Proff Peter
Published: February 2025

Objectives

The aim of this study was to clarify the applied initial forces and moments by different aligners of various materials and manufacturing methods.

Methods

The finite-element-method was used to analyze the forces and moments generated by the aligners on a maloccluded tooth. Plaster models of dental arches with a mesiorotated tooth 11 were fabricated, digitized and virtually analyzed. Four types of aligners with various layer thicknesses were selected: two splints with novel shape memory properties: a printable aligner made of the resin Tera Harz TC-85 DAC (Graphy Inc., South Korea) and a self-manufactured aligner consisting of the components polypropylene carbonate and thermoplastic polyurethane. The other two aligners were conventional, thermoformable aligners: CA® Pro Clear Aligner (Scheu Dental GmbH, Germany) and Erkodur-al (Erkodent Erich Kopp GmbH, Germany).

Results

The force and moment analyses showed that the thermoformable CA® Pro Clear Aligner exhibited the highest values. The thermoformed Erkodur-al aligner showed the lowest force loads for all layer thicknesses. The Graphy printed splint showed similar results compared to Erkodur-al at layer thicknesses of 0.40 mm and 0.50 mm.

Conclusions

To avoid periodontal overloading, aligners with lower force and moment delivery should be chosen for this type of tooth movement.

Authors: Ababneh Fuad A. , Abu-Sbeih Khaleel A.
Published: February 2025

Herbal teas are very popular drinks. Their contamination could cause health problems for the population. Therefore, it is important to ensure that common toxic elements, which are released into the environment, are not present at high levels. We used inductively coupled plasma mass spectrometry to determine the concentration of As, Pb, Cd, and Cr in the infusions of 16 different brands of herbal teas sold in Jordan. In addition, the Hg content of the infusions was determined using a mercury analyzer which is based on atomic absorption spectrophotometry. The estimated daily intake (EDI) was below the threshold recommended by the World Health Organization. The highest EDI was found for Pb with values that reached 9.22 × 10−2 μg kg−1 in sample T11, while Hg had the lowest values, which were less than or equal to 3.71 × 10−4 μg kg−1. The target hazard quotient, an estimate of non-carcinogenic effects, was found to be within the acceptable limits of the US Environmental Protection Agency (EPA) for both adults and children. Moreover, the incremental lifetime cancer risk values were also found to fall within the acceptable limits of the US EPA. These results confirm that the herbal tea brands sold in Jordan are safe for human consumption.
Forging CLIL Teacher Identities in Kazakhstan: Developmental Pathways of Two University Teachers
Authors: Philip Montgomery D. , De Costa Peter I. , Novitskaya Yuliya
Published: February 2025

As universities in Kazakhstan continue to address the challenges that come with developing English-medium instruction (EMI) programs, university Science, Technology, Engineering, and Mathematics (STEM) teachers need to develop capacities to teach in English, while their English teacher counterparts need to develop content-specific pedagogical knowledge. Content and Language Integrated Learning (CLIL) pedagogies, defined as the integration of both language and content curricular goals, have emerged as a vehicle to facilitate this development for both types of teachers. However, what it means to be a CLIL teacher may vary considerably as teachers leverage their professional knowledge and personal experiences. We, therefore, explore teachers’ conceptions of CLIL and how their disciplinary, linguistic, and pedagogical backgrounds enable or burden them to forge a “CLIL teacher” identity. This qualitative study illustrates the salient points of the journeys taken by two university teachers, one a specialist in oil and gas, the other an English teacher and teacher educator. Drawing on extended one-on-one interviews, we present two teachers’ experiences through a series of CLIL-informed workshops. Using a multidisciplinary analytical framework, we map the ways in which the two teacher participants negotiate their identities in relation to CLIL. The findings highlight the importance of understanding teacher experiences, particularly their language learning backgrounds, attitudes toward supporting student learning, and relationships with their colleagues as they work to adapt to teaching English and STEM subjects in university EMI contexts.
Numerical simulation and performance study of three-dimensional variable angle baffle micromixer
Authors: Chen Xinkun , Song Bao , Li Xiaoyu , Zou Jixu , Chen Xueye
Published: February 2025

In microfluidic systems, micromixers are of utmost importance for achieving efficient mixing. However, current micromixers still have deficiencies in mixing efficiency, which restricts their widespread application in fields such as biotechnology, chemical synthesis, and environmental analysis. This paper focuses on the influence of variable-angle baffles on the mixing efficiency of micromixers. By altering the geometric configurations of baffles, the mixing efficiency of solutions is enhanced. Specifically, the impacts of baffle direction, quantity, and height are explored. Additionally, groups of three baffles are utilized to investigate the effect of staggered heights on mixing. Through COMSOL simulations, it is found that the 45-degree structural baffle is highly conducive to solution mixing. An increment in baffle number prolongs the fluid mixing path, thereby augmenting the efficiency. Similarly, a rise in baffle height intensifies the fluid disturbance and elevates the mixing efficiency. Notably, setting a group of baffles to 0.15–0.05–0.1 mm is particularly advantageous for enhancing the mixing efficiency, as this configuration optimizes the fluid flow regime and promotes chaotic convection, thus significantly improving the micromixer’s performance.

Published: February 2025

Background

Males have a three times higher risk of a diagnosis of bladder cancer (Bca) than females. Sex hormone-binding globulin (SHBG) may be associated with Bca risk. However, the sex-specific role of SHBG in Bca remains unclear. In this study, we aimed to determine the role of SHBG in Bca.

Methods

A sex-specific univariable Mendelian randomization (MR) analysis involving 369,426 men and 395,375 women was conducted to assess the causal relationship between SHBG and testosterone and Bca risk. Sensitivity analyses and multivariable MR were conducted to confirm the robustness of our results. Linkage disequilibrium score regression assessed the genetic correlation between these diseases influenced by heredity.

Results

Univariable MR results showed that one-SD elevated SHBG was related to a low risk of Bca in males (OR: 0.60, 95% CI: 0.39–0.93; p = 0.022) but had no benefit in females. Genetically predicted BT was positively associated with Bca risk in males (OR: 1.59; 95% CI: 1.06–2.40; p  =  0.027). In multivariable MR, higher SHBG levels were not related to male Bca risk after controlling for BT.

Conclusions

Our findings do not provide evidence to support a causal relationship between SHBG and Bca risk in males although an association was observed in the univariable analysis. Further research is needed to identify the underlying pathways.
Lebensereignisse im Bildungsbereich als Erklärung für individuellen Sprachwandel
Authors: Wirtz Mason A. , Vergeiner Philip C.
Published: February 2025

Major life events (MLEs) in the educational domain such as graduating school or beginning a new degree set an important course for each individual’s life. However, the impact of such MLEs on patterns of individual-level language change across the lifespan, and how their impact may vary among individuals, is far from clear. In this article, we thus demonstrate the variation in patterns of individual-level perceived linguistic change affected by educational MLEs (i.e., graduating school, beginning a new degree, graduating university) among 181 Austrian participants with first language German. Our goal is to both quantitatively and qualitatively investigate which constellation of individual differences in event experiences and other psychosocial factors are associated with differences in reported individual-level linguistic change following educational MLEs. Bayesian modeling indicated that gender and proficiency in nonstandard varieties were particularly predictive of individual-level linguistic change. Qualitative analysis revealed a blended operation of socio-affective and language biography-related factors being associated with educational MLE-related change in the sociolinguistic repertoire.
Design and synthesis of 3-(azepan-1-ylsulfonyl)-N-aryl benzamide derivatives as potent carbonic anhydrase IX inhibitors with anticancer activities
Authors: Khanfar Mohammad A. , Saleh Mohammad
Published: February 2025

Carbonic anhydrase IX (CAIX) is known to be overexpressed in various tumors and plays a significant role in tumor development and progression. A series of 3-sulfonamide benzoate derivatives with a 7-membered azepane ring were synthesized and evaluated for their CAIX inhibitory activities. Most of the synthesized compounds successfully inhibited CAIX activities, exhibiting IC50 values in the low nanomolar range. The most potent CAIX inhibitor was compound 26, with an IC50 of 19 nM. A structure-activity relationship analysis of the synthesized compounds was conducted, and molecular docking revealed strong coordination with the catalytic Zn2+ metal, hydrophobic interactions of the azepane ring with a hydrophobic pocket, and π-stacking interactions of the aryl ring with an aromatic surface. The three most active analogues (8, 16, and 26) were further tested for their antiproliferative activities in the NCI-60 human tumor cell lines screen. Notably, compound 16 (CAIX, IC50 = 310 nM) demonstrated potent growth inhibitory effects against several cancer cell lines.
EU Accession to the ECHR: At the End of the Long and Winding Road?
Authors: Mohay Ágoston
Published: February 2025

Accession to the European Convention on Human Rights has been on the European Union’s agenda for decades. The Lisbon Treaty has removed the initial legal barriers, but actual accession has not been achieved to date: the reconciliation of the special characteristics of EU law with the Convention has proved to be a rather complex issue, illustrated well by Opinion 2/13 of the Court of Justice of the European Union (CJEU). The new draft accession agreement, which was drawn up during the relaunched negotiations, sought to address the issues raised by the Opinion 2/13, but questions remain, in particular regarding legal remedies in the Common Foreign and Security Policy (CFSP) as well as the EU law principle of mutual trust. Following an overview of the accession process so far, the paper concentrates on the analysis of these two selected issues, assessing the solutions included in (or indeed missing from) the 2023 draft.

Authors: Baydemir Recep
Published: February 2025

Türkiye’de son yıllarda genelde göç olgusu özelde de Suriyeliler, literatürde alevlenmiş bir konu olarak karşımıza çıkmaktadır. Suriyelilerle ilgili her gün neredeyse onlarca yeni “akademik” çalışma yayımlanırken, bu anlamda binlerce çalışmanın olduğu geniş bir literatür birikmiştir. Ancak, bu literatürde, metodolojik sorunlar, dilin ve terimlerin yanlış kullanımı, önyargılar, bulguların genelleme biçimi, kuramsal hatalar, yanlış kavram kullanımları gibi ciddi hataların ve eksikliklerin olduğu çalışmalar göze çarpmaktadır. Bu araştırmada, Suriyelilerle ilgili yapılmış akademik çalışmalardaki metodolojik sorunlar, yanlış dil ve kavram kullanımları, önyargılar ve genelleme eğilimleri vurgulanarak mevcut literatür eleştiriye tabi tutulmaktadır. Araştırmada, Google Scholar, Dergipark, Ulakbim TR Dizin ve YÖK Ulusal Tez Merkezi veri tabanları üzerinden “Suriyeli” ve “Suriyeliler” kelimeleri girilerek genel bir tarama yapılmıştır. Tarama sonrası ortaya çıkan çalışmalar, tematik olarak gruplandırılmıştır. Böylelikle, doğrudan veya dolaylı olarak Suriyelilerle ilgili yapılmış çalışmalar belirlenerek, bu çalışmaların genel bir çerçevesi oluşturulmaya çalışılmıştır. Araştırmada, Suriyeliler üzerine niceliksel açıdan zengin bir literatürün biriktiği ve bu literatürün Suriyelileri çeşitli açılardan anlamaya katkı sağladığı, ancak söz konusu literatürün Suriyelilerin portresini henüz ortaya koymaktan uzak olduğu vurgulanmaktadır.

Altered types 2 and 3 deiodinases (D2 and D3) can disrupt thyroid hormone metabolism and contribute to nonthyroidal illness syndrome (NTIS). The impact of the colocalization of D2 and D3, and their expression in immune cells isolated from critically ill patients are still not fully understood. Our objective was to assess the D2 and D3 in the neutrophils and monocytes of patients admitted to the intensive care unit (ICU) for any cause. Blood samples were collected from ninety-six ICU patients at admission and on day seven. We employed different cell gradients and flow cytometry to separate and purify cells from whole blood. Parameters indicating redox balance were measured, including total carbonyls, sulfhydryl content, and glutathione (GSH) levels. The expression and colocalization of DIO2 and DIO3 were evaluated through RNAscope, real-time PCR (polymerase chain reaction) , and immunofluorescence. The formation of carbonyls, a marker for oxidative damage to proteins, was elevated in all patients, while sulfhydryl and GSH levels were found to be reduced. The expression of DIO2 and DIO3 in neutrophils and monocytes from both surviving and deceased patients demonstrated significant variations in localization. Notably, elevated levels of D3 protein showed distinct distribution patterns between the groups. Levels of T3 in each cell type varied and were correlated with patient outcomes. The specific distribution of these enzymes has also been associated with prognosis. The set of these findings enhances our understanding of the pathophysiology of NTIS and may provide valuable information for prognostic assessments.
Median cervical cleft: A rare disease: Case report in a newborn
Authors: Hernando Vallejo Chaves Saul , Trujillo Sandra Sanchez , Martina Omaira Gomez , Fanny Portilla
Published: February 2025

Congenital midline cervical cleft is a rare condition, with an incidence of less than 2% among congenital malformations. Its etiology is related to defects in the fusion of the first branchial arches. The clinical findings of a fibrous cord with skin involvement in the midline cervical region allow for an early and accurate diagnosis in most cases without requiring further studies. It was fully described by Ombreadanne in 1946. Although it can be followed in the first day of life and the diagnosis is typically made on the basis of the clinical presentation of the action of the lesion at birth, the cleft may not appear very striking in a newborn. When observed at birth, the characteristic features are a defect in the ventral area of the neck with a subcutaneous fibrous cord and a nipple-like projection at the top and a sinus or fistulous tract at the lower end of the defect. The defect is located between the mental areas superiorly to the suprasternal notch, inferiorly with variable length and width. Most cases are sporadic and it is more common in Caucasian girls.

Authors: Jing Shuoyu , Wan Pa Wan Ahmad Munsif , Awang Mohd Mahzan
Published: February 2025

Background and Study Aim. Depression and anxiety are prevalent mental health challenges among college students. International student-athletes abroad face distinct mental health challenges compared to general students due to their dual roles as athletes and international students. The purpose of this study was to analyze the network structure and characteristics of anxiety and depression in Chinese international student-athletes during study abroad from a network perspective.
Material and Methods. A network analysis approach was used in this study. A total of 219 Chinese student-athletes studying in Malaysia were recruited for this research, and their demographic characteristics were collected. The Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9) were used to assess symptoms of anxiety and depression.
Results. The results revealed that the strongest relationship in the network was between psychomotor issues (PHQ8) and self-harming tendencies (PHQ9). Nervousness (GAD1) demonstrated the highest node strength, followed by sleep issues (PHQ3) and guilty feelings (PHQ6). Psychomotor issues (PHQ8) exhibited the highest node expected influence value. Nervousness (GAD1) was identified as the most important bridging symptom. The network demonstrated good accuracy in stability tests. Three symptom communities were identified in the community detection results.
Conclusions. This study highlights the importance of addressing mental health concerns among overseas student-athletes. The findings could inform the future design of intervention strategies targeting core symptoms, thereby reducing levels of anxiety and depression among international student-athletes during their studies abroad. Additionally, the network analysis perspective offers new research avenues for studying the unique characteristics of sports groups in the future.

Published: February 2025

Background and Study Aim. Flexibility and strength endurance are essential components of tennis performance. This study aims to evaluate the effectiveness of bodyweight circuit training (BCT) in enhancing flexibility and strength endurance in male university tennis players.
Materials and Methods. This study employed a true experimental design with a pretest-posttest control group. A total of 30 male tennis players, aged 19–23 years, were recruited from a university. Participants were randomly assigned to either a control group (CTr, n=15) or a training group (TRg, n=15) based on predefined criteria. The training group underwent a bodyweight circuit training (BCT) program three times per week for four weeks. Flexibility was assessed using the Sit and Reach Test. Strength endurance was evaluated through three tests: upper body strength endurance with the 60-second Push-Up Test, abdominal strength endurance with the 60-second Sit-Up Test, and back strength endurance with the 60-second Back Extension Test. Measurements were taken at baseline (pre) and after four weeks (post). Data analysis was conducted using paired and independent sample t-tests, with a significance level set at 5%.
Results. Significant improvements in flexibility, upper body strength endurance, abdominal strength endurance, and back strength endurance were observed in the training group (TRg) between pre- and post-intervention (p ≤ 0.05). In contrast, no significant changes were found in the control group (CTr) (p ≥ 0.05). At baseline, no significant differences were detected between the TRg and CTr groups (p ≥ 0.05). However, post-intervention analysis revealed significantly greater improvements in the TRg group compared to the CTr group (p ≤ 0.05).
Conclusions. BCT implementation in training programs may contribute to improved physical performance. These findings suggest that BCT could be integrated into structured training regimens to support athletic development.
Kadry techniczne w województwie kieleckim w okresie międzywojennym (1919‒1939)
Authors: Słabińska Elżbieta
Published: February 2025

Warunkiem rozwoju nowoczesnego przemysłu były w międzywojniu kadry techniczne – inżynierowie, technicy i majstrowie. W województwie kieleckim prezentowały się one dość skromnie, mimo że na jego obszarze zlokalizowane były trzy ważne okręgi przemysłowe: Zagłębie Dąbrowskie, okręgi częstochowski i staropolski. Funkcjonowały spółki akcyjne w kluczowych gałęziach przemysłu, mianowicie górnictwie i hutnictwie, przemyśle metalowym i włókienniczym. Istniały też średnie i małe zakłady przemysłowe, w których stosowano nowoczesne maszyny i technologie. Inżynierowie z wyższym wykształceniem technicznym różnych specjalności, Polacy i cudzoziemcy, znajdowali zatrudnienie najczęściej w spółkach. Najbardziej prestiżowa i popłatna była praca w spółkach górniczych; w nich również stawiano najwyższe wymagania dotyczące wykształcenia, ujęte w prawie górniczym. Starannie dobierano również kadrę kierowniczą w dużych i średnich przedsiębiorstwach państwowych. Najsłabszą obsadę miały drobne zakłady indywidualne. W nich wyższym wykształceniem legitymował się zwykle właściciel lub dyrektor.
Zarządzanie przedsiębiorstwem było zajęciem prestiżowym. Poza wymaganiami dotyczącymi wykształcenia wysoko ceniono praktykę zawodową na podobnych stanowiskach, znajomości i koligacje oraz savoir-vivre. Ważna była umiejętność nawiązywania właściwych relacji z podwładnymi.
Kadra zarządzająca była hojnie wynagradzana. Najwyższe dochody osiągała w spółkach akcyjnych. Stanowiska te były na tyle intratne, że dochody na nich osiągane ukrywano, by zmniejszyć stawki podatkowe. Diametralnie niższe zarobki miał personel specjalistyczny średniego i niższego szczebla.

Para isso, foi adotada uma abordagem qualitativa, baseada na análise de documentos legais e regulamentares pertinentes ao tema. Os resultados do estudo indicam que, apesar das várias políticas implementadas pelo Estado de São Paulo para promover a inclusão de alunos em diáspora, ainda existem desafios significativos. As políticas, incluindo as Resoluções da Secretaria da Educação e o Currículo Paulista, têm contribuído para garantir o acesso à educação para imigrantes e refugiados, especialmente em relação à matrícula de alunos sem documentação e à adaptação curricular para refletir a diversidade cultural. No entanto, foram identificadas limitações na implementação prática dessas políticas. Barreiras linguísticas e culturais continuam a impactar a experiência escolar desses alunos, afetando seu desempenho acadêmico e sua integração social. Portanto, o estudo conclui que é fundamental um compromisso contínuo com a inclusão e a equidade para superar essas barreiras e garantir que todos os alunos em diáspora recebam o suporte necessário para sua plena integração no sistema educacional paulista.

Polyphenolic compounds of plant origin are known for their positive effects on the human body due to their antioxidant, anti-inflammatory, antiviral, etc. effects, but they have limitations in terms of use as preventive agents due to their low bioavailability, which is caused by their chemical instability and insolubility in water. One of the ways to increase the bioavailability of polyphenols is to use various nanocarriers (liposomes, micelles, nanoemulsions, metal complexes, nano-gels, etc.) The most commonly used biopolymers in the development of systems for stabilizing and increasing the solubility of polyphenolic compounds are biocompatible and biodegradable. In this context, non-starch polysaccharides are attracting increasing attention of researchers due to their gastrointestinal resistance, most of them are able to provide controlled release, targeted delivery and water solubility. One of the polyphenolic compounds with low bioavailability is curcumin, the stability of which can be increased by complexation with certain polysaccharides. This article is devoted to the substantiation of the possibility of increasing the stability of curcumin by its complexation with xylan. Xylan was obtained by alkaline extraction from corn cobs. The complex of curcumin with xylan was obtained by a pH-controlled method. The rational conditions of complexation were substantiated. The formation of the curcumin-xylan complex and the preservation of the curcumin structure after complexation were proved by spectroscopic methods. It is shown that curcumin in the complex has higher thermo- and photostability compared to free curcumin. Complexation with xylan has been shown to increase the stability of curcumin in vitro conditions imitating the human gastrointestinal tract. The curcumin-xylan complex can be used as a physiologically functional ingredient in food production and as a dietary supplement.
POSSIBILITIES TO REDUCE THE SALT CONTENT IN DAIRY PRODUCTS

Published: February 2025

Salt application in milk processing refers mainly to cheeses, processed cheeses and dairy spreads. Although salt is technologically unavoidable in these dairy products, there are some possibilities to reduce salt content, but only maximally to the technologically acceptable levels. Because cheeses are very popular, most discussions on how to reduce salt content were oriented to this area, and special emphasis is rendered to salt utilization in cheese-making technology. But limitations are discussed as well. Processed cheeses demand melting salts for proper melting, and these salts became a part of the dairy product. Therefore, when consuming processed cheeses, these salts contribute to elevated levels in our body, and as such have adverse effects on cardiovascular potential, hypertension… But fortunately, processed cheeses are not consumed in large quantities and there is still some maneuverable space to reduce melting salts content, without any harm to technological process. Dairy spreads, either milk or cheese, natural or supplemented with diverse mixtures of herbs, spices, meat, garlic et al. technologically do not need salt, but they are still salted. Salt is added only as taste enhancer, to improve taste. So, salt can be completely avoided from spreads, but consumers probably will not agree to remove salt completely. Therefore, detailed consumer research should be made to established what is the minimum salt content in spreads, they tolerate. And finally, salted variety of butter is discussed as well. Butter is one of the dairy products, that is least loaded with additives. Only beta-carotene and/or salt are allowed. Beta-carotene is used to unify seasonal discolorations and salt to produce salted varieties of butter. Although not popular locally, some attention is focused to salt in butter as well, and possible reductions. Hereforth, decrease of salt application in certain dairy products is discussed.
VALIDATION OF A CHROMATOGRAPHIC METHOD FOR THE MCPD DETERMINATION IN VEGETABLE OILS

Today, esters of 3-monochloropropane-1,2-diol (3-MCPD-E) and glycidol (GE) remain one of the most pressing food safety issues, so a thorough study of their structure, formation mechanisms and control methods is an urgent issue. 3-MCPD and GE are fat-soluble toxic substances that can be formed in vegetable oils during their production and processing. Chloropropanols are by-products formed as a result of acid hydrolysis of glycerol lipids at elevated temperatures, during production or storage, and in the process of deodorization of edible oils. As a rule, 3-MCPD and GE are formed as a result of high-temperature exposure to fats, and they have carcinogenic, genotoxic, nephrotoxic and other types of negative effects on the human body. That is why their content is strictly regulated and must be controlled both in raw materials and in final products based on them. The direct determination of glycidol esters and fatty acid esters of 3-MCPD is performed by HPLC/MS/MS, but this method is difficult to use in practice due to the large number of components to be determined (84) and the lack of analytical standards. The most common indirect methods of control are when all esters of glycidol and 3-MCPD decompose to just glycidol and 3-monochloropropanediol, respectively. One of the earliest methods of determination adopted by the International Organization for Standardization is the ISO 18363-1:2015 method, which provided quantitative determination of 3-MCPD by alkaline decomposition of 3-MCPD esters and glycidol to 3-MCPD. The determination of glycidol esters in terms of glycidol was carried out by recalculating the difference in the quantitative results of two injections. The main disadvantage of this method is the inaccurate quantitative result for glycidol, since the method is based on the assumption that there are no other substances that react with inorganic chloride to form 3-MCPD.  The following were the standardized methods ISO 18363-2:2018 and ISO 18363-3:2017. Both are already much more accurate than the previous one, but have a very long decomposition reaction time of more than 16 hours. This makes these methods very limited in their applicability to industries, but because of their direct quantification, they provide more accurate results for laboratories that issue certificates of analysis and are responsible for the quality of the values obtained.
Reinscribing History through Docupoetry
Authors: Chicalese Jackie
Published: February 2025

This article explores documentary poetry, or docupoerty, as a method of counterstory. Emphasizing Don Mee Choi's 2020 DMZ Colony, I argue that docupoetry provides a methodology for writers of color to interviene in majoritarian narrivitization and construct their own identities within and against broader systemic and ideological frameworks. These constructions serve to resist totalizing narratives and invent avenues for transformational resistance and open up considerations of how other creative genres can serve as rhetorically rich methods of counterstory.
Flames of (In)Justice
Authors: Revier Kevin
Published: February 2025

Flames of (In)Justice is a parable that speaks to ongoing conservative efforts against Critical Race Theory (CRT) in public education. In the parable, fictitious white suburbanites commence an annual Book Burning Day, where they enflame government-designated “Race Books.” They do so in commemoration of legislation that bans “Race Speech,” defined as all speech that mentions race unless during the federally recognized holiday. Otherwise, lawmakers contend, speech that discusses race is discriminatory and divisive in a post-racial society: it threatens a nation built on ideals of equality, individualism, and colorblindness. In writing the story, I highlight an enduring truth: of a white investment in colorblind racism not so divided by political lines. Indeed, I wrote the story by drawing on my personal experiences growing up white and learning—or not learning—about race in a predominantly white suburb. As such, I recommend that whites engage in counterstory in a way that elucidates whiteness, not obscures it.

The objective of this study was to analyze the psychological responses of the Brazilian population and understand their level of anxiety, depression, and stress during different times of the COVID-19 pandemic, as well as how the PA level and sociodemographic aspects may have influenced them. This longitudinal study collected data in two periods: April/May 2020 (T1) at the beginning of the COVID-19 pandemic with restrictions and social distancing indication (during the lockdown), and October/November 2021 (T2) period with fewer restrictions and vaccines available in Brazil (after the lockdown). Data were collected online, including sociodemographic information (age, gender, education), mental health by the Depression, Anxiety, and Stress Scale (DASS-21), and estimated PA levels using the International Physical Activity Questionnaire (IPAQ) short version. Statistical analysis used generalized linear regression models to evaluate the impact of time, sociodemographic aspects, and PA on the risk of depression, anxiety, and stress between periods. Adjusted risk probabilities and Odds Ratio (OR) with 95% confidence intervals (95% CI) were calculated with a 5% significance level. Comparisons between T2 and T1 showed an increased risk for depression (OR=1.48 [95%CI=1.03;2.12]), anxiety (2.66 [1.70;4.17]), and stress (1.95 [1.36;2.79]). Low PA levels were associated with a higher risk of depression (2.08 [1.14;3.82]) and stress (2.03 [1.09;3.80]) but not anxiety in the comparison between T2 and T1. The findings highlight the increased risk for depression, anxiety, and stress in T2 and suggest PA promotion as a possibility for mental health care.

Background

Acute kidney injury following ischemia−reperfusion remains a substantial perioperative challenge lacking effective treatment. p21-activated kinase 4 (PAK4), a downstream effector of Rho GTPase, has been explored in hepatic ischemia−reperfusion injury, but its role in renal ischemia−reperfusion is unknown.

Methods

Wild-type and proximal tubule-specific Pak4 knockout mice underwent 25 min of ischemia followed by 24 h of reperfusion injury. Primary tubular cells and HK-2 cells were exposed to hypoxia−reoxygenation injury to investigate the in vitro impact of PAK4. Selective degradation of PAK4 was employed using proteolysis-targeting chimeras (PROTAC) to ameliorate acute kidney injury.

Results

Post-ischemia−reperfusion, the expression of PAK4 was upregulated through hypoxia-inducible factor 1 alpha in mouse kidneys. Deletion of PAK4 in proximal tubule cells, but not in myeloid cells, significantly mitigated ischemia−reperfusion-induced acute kidney injury, as evidenced by decreased levels of blood urea nitrogen, creatinine, tubular necrosis, apoptosis, macrophage infiltration, and lipid accumulation compared to control mice. Further investigation revealed that PAK4 phosphorylated glutathione peroxidase 3 at T47, leading to its proteasomal degradation. Additionally, pretreatment of mice with the PAK4 PROTAC preserved glutathione peroxidase 3 and enhanced fatty acid β-oxidation, thereby protecting against acute kidney injury. In kidney tissues from people with a kidney transplant, elevated levels of PAK4 protein and phosphorylation of glutathione peroxidase 3 at T47 were observed.

Conclusions

Renal tubular PAK4 contributes to tissue damage during ischemia−reperfusion injury, while PAK4 PROTAC mitigates ischemia−reperfusion injury by reducing oxidative stress and promoting fatty acid β-oxidation.
