Authors: Chen Feng , Yang Enhui , Zhang Yuansi , Zhang Yu 
Published: June 2024

IntroductionThis study sought to use the latest Life's Essential 8 scoring tool to obtain information on the relationship between serum vitamin D concentration and adolescent cardiovascular health (CVH).Material and methodsA total of 1,819 teenagers aged 16–19 were enrolled. Associations between serum vitamin D concentrations and CVH ratings were estimated using multiple linear regression and multinomial logistic regression methods, and the dose–response relationship was examined by restricted cubic spline analysis.ResultsAfter adjusting for all confounding factors, serum vitamin D concentrations were positively correlated with CVH scores (β=0.12; 95% CI: 0.09-0.14, p<0.001). Among the sex and race subgroups, the correlation was stronger in male, Mexican American and Non-Hispanic Black participants, with ORs of 1.05 (95% CI: 1.03-1.07), 1.06 (95% CI: 1.04-1.08), p=0.002), 1.07 (95% CI: 1.03-1.11), 1.09 (95% CI: 1.05-1.14), p=0.01, 1.04 (95% CI: 1.01-1.06), and 1.05 (95% CI: 1.02-1.09), p=0.01, respectively. Serum vitamin D concentrations had a nonlinear relationship with CVH ratings. CVH scores grew with serum vitamin D concentrations up to the inflection point (86 nmol/L) (β=0.17 (95% CI: 0.135-0.206, p<0.001). When serum vitamin D concentrations exceeded 86 nmol/L, CVH scores were not associated with serum vitamin D concentrations.ConclusionsThe study identifies a nonlinear relationship between serum vitamin D levels and CVH in US adolescents aged 16-19, with an inflection point at 86 nmol/L. These findings underscore the importance of vitamin D in adolescent cardiovascular health and suggest the need for targeted health strategies, particularly in high-risk groups such as male, Mexican American, and Non-Hispanic Black teenagers.

IntroductionAlzheimer's disease (AD) is triggered by biological mechanisms such as neuroinflammation and oxidative stress. Endoplasmic reticulum (ER) stress can lead to the expression of molecular chaperones in the ER, which helps in restoring cellular homeostasis. Researchers have highlighted the role of ER stress in the progression of AD, suggesting that regulating it could be a potential treatment strategy for AD.Material and methodsWe induced AD in mice by injecting amyloid beta-peptide 25-35 (Aβ25-35) bilaterally into the CA1 of the dorsal hippocampus. Some mice were administered celastrol intraperitoneally before the Aβ25-35 injection, while others received it after the injection. The mice underwent the Barnes maze cognitive test and Morris water maze test to assess learning and memory impairment. Levels of interleukin (IL)-1β, tumor necrosis factor alpha, and IL-10 were measured to evaluate inflammation, while total antioxidant capacity, catalase, Malondialdehyde, and superoxide dismutase levels were analyzed to estimate oxidative stress.ResultsOur study showed that pre-treatment with celastrol could prevent learning and memory decline in AD mice by reducing inflammation and oxidative stress. Celastrol also inhibited AD-induced inflammation and oxidative stress. Additionally, celastrol suppressed AD progression by targeting ER stress. These results suggest that celastrol treatment could be beneficial in addressing learning and memory deficits in AD, paving the way for potential neuroprotective treatments.ConclusionsCelastrol effectively improved learning and memory impairments in AD mice by targeting ER stress-induced inflammation and oxidative stress. This highlights the potential of celastrol as a therapeutic agent for AD.
Assessment of the Impact of Land Use and Land Cover Change on the Surface Runoff of Hadejia River System, Kano, Nigeria

Published: June 2024

Land use and land cover changes, mostly driven by anthropogenic activities, affect the processes of the water cycle. The impacts of land use (LU) and land cover (LC) changes between 1995 and 2015 on the surface runoff of the Hadejia River System (HRS) were investigated. The LULC changes obtained through re-classifications of selected Landsat satellite images and their effects on runoff peak discharges and volumes were assessed using selected hydrologic models for runoff generation and routing available within the HEC-HMS. Physically-based parameters of the models were estimated from the LULC change maps together with a digital elevation model and soil datasets of the basin. The simulated flows from the 90 sub-catchments were routed to the basin outlet afterwards to obtain the accrued effects in the entire river basin. Model results obtained generally revealed significant and varying increases in the runoff peak discharges and volumes within some sub-basins in the whole catchment, though the change was not significant at the basin outlet. In the sub-catchments within Kano and Jigawa states, increase between 15-20% and 10-15% were observed in the peak discharge respectively. These are the areas with the highest increase in agricultural activities and urbanization within the whole catchment. In the entire basin, however, the flood peak discharges and volumes increased by at least 3.57% and 8.18% respectively. From these results, the study concludes that changes were more pronounced in Kano and Jigawa states due to the increase of urbanization and farming activities in those areas, leading to reduction of infiltration and hence, increase in surface runoff. The study successfully outlined the hydrological consequences of land cover changes, emphasizing the importance of sustainable land use and catchment management strategies. Hence, integration of remote sensing, GIS, and the hydrological model (HEC-HMS) can be used to solve hydrological problems in a river basin.

Abstract. Litter decomposition is an important factor affecting local and global C cycles. It is known that decomposition through soil microbial activity in ecosystems is mainly influenced by soil type and climatic conditions. However, for agroecosystems, there remains a need for a better understanding of how management practices influence litter decomposition. This study examined the effect of different management practices on decomposition at 29 sites with long-term (mean duration of 38 years) field experiments (LTEs) using the Tea Bag Index (TBI) protocol with standard litter (rooibos and green tea) developed by Keuskamp et al. (2013). The objective was to determine if the TBI decomposition rate (k) and stabilization factor (S) are sensitive enough to detect differences in litter decomposition between management practices as well as how they interact with edaphic factors, crop type and local climatic conditions. Tea bags were buried and collected after ∼90 d at 16 Austrian and 13 Swedish sites. The treatments in the Austrian LTEs focused on mineral and organic fertilizer application, tillage systems and crop residue management, whereas those in Sweden addressed cropping systems, mineral fertilizer application and tillage systems. The results for Austria showed that the incorporation of crop residue and high-N fertilizer application increased k, compared with crop residue removal and low or no N application, respectively. Minimum tillage had significantly higher k compared with reduced and conventional tillage. In Sweden, fertilized plots showed higher S than non-fertilized plots and high-N fertilizer had the highest k. Growing spring cereal led to higher k than forage crops. Random forest regressions for Austria and Sweden jointly showed that k and S were mainly governed by climatic conditions, which explained more than 70 % of their variation. However, under similar climatic conditions, management practices strongly influenced decomposition dynamics. It would be appropriate to apply the TBI approach to a more large-scale network using LTEs for agroecosystems, in order to improve the index's usefulness as an indicator of the effect of management practices on litter decomposition dynamics, particularly linking it with the potential for C storage.
Les singularités de l’œuvre de Maryse Condé et sa réception en Espagne
Authors: Cremades Cano Isaac David 
Published: June 2024

Un caractère certainement inclassable semble définir l’œuvre de l’écrivaine et intellectuelle francophone d’origine guadeloupéenne Maryse Condé. Face à cette complexité, nous prétendons d’abord répondre à la question : pouvons-nous considérer Maryse Condé comme médiatrice d’une certaine littérature africaine en Espagne ? Ce travail parte donc d’une réflexion autour de cette ambigüité Afrique/Antilles, pour ainsi introduire une analyse de la réception de ce corpus singulier en Espagne. Avec l’objectif principal donc de déterminer les phases et les modalités de circulation liées à ce transfert culturel particulier, nous avons encadré nos recherches dans un domaine essentiellement scientifique. Cette délimitation de l’étude nous a permis finalement de nous interroger sur les limitations et les perspectives de réception de son œuvre en Espagne, ainsi que de constater le rôle joué par Maryse Condé dans le transfert transnational de la littérature africaine dans ce pays européen et hispanophone.
Géopoétiques transcontinentales et vitales dans la littérature leclézienne
Authors: Sueza Espejo María José 
Published: June 2024

Los espacios que conforman el universo vital e imaginario de J.M.G. Le Clézio (1940) están llenos de diversidad (Nigeria, México, Marruecos, Mauricio...), y están vinculados a sus experiencias, felices o terribles, ocurridas por casualidad o libremente elegidas, pero sentidas profundamente desde su más tierna infancia. Las coordenadas geográficas intercontinentales, e incluso transoceánicas, que forman parte de su existencia, a través de vínculos familiares o intereses personales, quedan incluidas en su literatura autobiográfica y su autoficción. Por ello, la literatura lecleziana ofrece numerosas recreaciones muy cuidadas y poéticas de su topografía, su orografía, su flora y su fauna…, además de la de los elementos indisociables de las descripciones leclezianas: el sol, el mar, el viento, el cielo, la noche. La geopoética lecleziana vivida, disfrutada y transmitida a través de la prosa poética de sus historias nos servirá igualmente para argumentar el compromiso ecológico y humanista del autor que se desprende de ellas.

Abstract
The Bayan Obo ore deposit is the largest rare earth element (REE) deposit in the world and has been assumed to be hosted in dolomite that was folded in a syncline. This has been challenged by results from drill holes and low-resistivity, controlled-source audio-frequency magnetotellurics (CSAMT) survey. In this paper, we present structural analysis of clastic sedimentary rocks from around the deposit, their relationship with carbonatite, and the orientations of the carbonatite bodies and dikes to constrain the possible configuration of carbonatite. Clastic sedimentary rocks underwent mylonitic deformation to slate, metasandstone, and metaconglomerate, displaying dramatic changes of thickness along strike. Slates locally preserve intrafolial folds and hook folds bounded by foliations; metasandstones have parallel layers of recrystallized and preferred-orientated quartz aggregations; metaconglomerates contain flattened pebbles with Flinn k values of 0.01 to 0.05 and 0. The above structures and foliations were crosscut and intruded by carbonatite and associated fenite, demonstrating preintrusion transposition of original bedding to steep foliation. Preintrusion foliation provides zones of weakness that were exploited by upwelling of carbonatite magma. Northeast-SW–striking left-stepping en echelon carbonatite dikes and E-W–striking carbonatite bodies indicate that the carbonatite was emplaced in a sinistral transtensional zone. The northern and southern segments of the carbonatite bodies are parallel to the steep foliation at shallow depths and merge together at depth, constraining a Y-shaped configuration, consistent with the low resistivity result of the CSAMT survey. The newly recognized Y-shaped morphology indicates that the carbonatite extends deeper than 1,775.4 m, more than twice the previously inferred maximum depth of the syncline model, and contributes to a significant &gt;1.78 times increase in global potential RE2O3 resources than previously estimated in 2021.

Refleksi Strategi Perang Vietnam Terhadap Pendekatan Prancis dan Amerika Serikat
Authors: Leo Sianipar  , Sri Sundari  
Published: June 2024

Perang Vietnam melawan Prancis dimulai dengan penjajahan Prancis dan pendudukan Vietnam selama hampir 100 tahun. Kolonialisme Prancis menimbulkan banyak ketidakpuasan dan perlawanan dari masyarakat Vietnam, terutama dari kaum nasionalis Vietnam yang ingin membebaskan negaranya dari pendudukan asing. Gerakan kemerdekaan Vietnam semakin kuat setelah Perang Dunia II, ketika Prancis mencoba mengembalikan kendali mereka atas Vietnam. Refleksi Strategi Perjuangan yang Dilakukan Bangsa Vietnam Melawan Kolonisasi Prancis dan Amerika Serikat adalah mempelajari dan menganalisis strategi yang digunakan oleh bangsa Vietnam dalam melawan penjajahan Prancis dan Amerika Serikat pada masa itu. Pada masa penjajahan Prancis di Vietnam, ada beberapa aspek bidang Ipoleksosbud yang mempengaruhi hubungan kedua negara. Amerika Serikat (AS) juga mempengaruhi beberapa aspek ideologi, politik, ekonomi, sosial dan budaya di Vietnam. Semua aspek ini mempengaruhi hubungan antara AS dan Vietnam selama perang. Pengaruh AS di bidang Ipoleksosbud menjadi salah satu alasan perlawanan dan perjuangan kemerdekaan rakyat Vietnam. Dengan memperkuat kemampuan perang gerilya, Indonesia dapat memperoleh keuntungan taktis dalam pertempuran dan meningkatkan kemampuan pertahanan negara secara keseluruhan dan penting juga untuk diingat bahwa strategi pertahanan negara juga harus membangun doktrin pertahanan yang adaptif, efektif, dan dapat menghadapi berbagai ancaman yang muncul dengan membangun keseimbangan dengan kekuatan militer konvensional.
