Published: October 2024

The measurement of wellness among Indigenous Peoples is crucial to understanding the needs of communities today and for generations to come. Here, we summarize the extant research on assessments relevant to measuring the wellness of Indigenous children in Canada through an examination of existing international best-practices. A thoughtful identification of wellness metrics aligned with Indigenous cultural contexts is important because in the past, wellness assessments that were not co-developed by Indigenous partners have perpetuated systemic harms. A scoping review of existing measures across Canada, the United States, Australia and New Zealand was completed consistent with the PRISMA guidelines across five databases. These guidelines provided guidance for the process of the review, as well as the structure for this paper. Search terms included "Indigenous" or "Aboriginal”, "wellness", “child-welfare”, "children”, “families" and “framework” or “measure”. In total 896 abstracts were screened. Of these, 88 articles were reviewed, 16 measures and four frameworks were identified as most relevant to our work. All efforts were led by Indigenous students in keeping with Traditional Ways of Being and Knowing as well as self-determination practices. Semi-structured interviews were also conducted with four Indigenous community members in order to advise the process of developing such a project and to gauge considerations on the appropriateness of assessing wellness in our communities. Results highlight a unique set of factors to consider from an Indigenous values perspective when assessing child wellness. The most salient of these include incorporating elements of self-determination in both measure development and usage. Themes of family, community, and wholism were also emphasized. While this exemplifies an emerging assessment base for measuring wellness, minimal work to date is directly designed to be relevant for Indigenous children or youth. Moving forward, we will seek to fill this gap by supporting the development of a wellness measure with potential to multi-contextual relevance to promote the adequate and equitable dispersion of supports and resources to families and communities.

The purpose of this article is to determine the similarities in the context of environmental practices and sustainability of twelve South American countries and compares the environmental sustainability performance with six principal components. A multivariate analysis as a hierarchical method was carried out with 12 countries of South American with seventeen sustainable environmental indicators, secondary official data sources were consulted, namely the databases of ECLAC (Economic Commission for Latin America and the Caribbean), applying eigenvector and eigenvalues from the correlation matrix and Ward's method with squared Euclidean distances.
The results suggest that the initial jumps in terms of distance are small. accordingly, the twelve countries analysed in study are grouped into five clusters. Deepening then in the perspective of characteristics of each cluster, CL1: Colombia, Venezuela, Suriname, Argentina and Bolivia; CL2: Guyana, Paraguay, Uruguay and Peru; CL3: Brazil; CL4: Ecuador; CL5: Chile. The research highlights significant differences among these South American countries, clustering those presenting similar patterns of behaviour and identifying the best performers. We argue that biodiversity must be protected and encouraged, and awareness raised of the importance of environmental sustainability and support the impact of climate change. Argentina, Uruguay and Chile face severe scarcity water issues and temperatures have risen in every country, but especially in Brazil, Colombia, Ecuador, Paraguay, Suriname, Venezuela.

Los antioxidantes son moléculas que se encuentran en los seres vivos (células, plantas, animales y el hombre), encargadas de retardar la oxidación de otras moléculas, en el proceso de envejecimiento a lo largo de los años y esta degeneración se realiza a través de la oxidación. En la actualidad se ha incrementado el interés por nuevas fuentes naturales de antioxidantes debido a dos razones principales: la primera es que presentan comprobados efectos benéficos sobre la salud, ya que contrarrestan la acción de los radicales libres, la segunda es que algunos antioxidantes sintéticos utilizados en la industria alimenticia que poseen efectos tóxicos, se acumulan en el tejido graso y han demostrado ser carcinógenos. Tiene como objetivo identificar los antioxidantes de las 28 especies aromáticas y medicinales existentes en el instituto con vista a fortalecer la calidad de vida, el aporte nutricional, empoderar sus hábitos alimentarios y su consumo. Se utilizó el método reporte bibliográfico, método genérico. En esta revisión se caracterizó los tipos de antioxidantes Hidrofílicos (Solubles en Agua), Hidrofóbicos (Solubles en grasa) y otros tipos de antioxidantes como los polifenoles y dentro de ellos se encuentran los Flavonoides (inhiben la enzima Oxidaza, evita la oxidación) e Isoflavonas (elimina RL e impiden crecimiento de mutaciones en el ADN) que eliminan radicales libres (RL). La Quercetina (pertenece al grupo de los flavonoides) capta y eliminan RL, facilitan la creación de antioxidantes endógenos, Una vez caracterizado los antioxidantes, se concibió una búsqueda de los tipos de antioxidantes que presentan las 28 especies de aromáticas cultivadas en el IIHLD. Se concluye que los antioxidantes identificados en las 28 especies aromáticas y medicinales constituyen una valiosa información para la salud humana. El conocimiento del valor nutricional de las plantas aromáticas y medicinales crea una cultura de consumo de los mismos en sus hábitos alimentarios. El consumo se debe realizar en pequeñas dosis para evitar efectos adversos en la salud, preferiblemente consumir antioxidantes naturales sobre los genéricos. Todas las especies identificadas en el IIHLD poseen antioxidantes naturales.

Highlights:1. This research provides important information regarding the food safety of smoked tatihu (yellowfin tuna) sold in several traditional markets in Ambon, Indonesia.2. We find that smoked tatihu fish samples examined at 2 of 3 traditional markets in Ambon city are unsafe for consumption according to the Indonesian National Standard due to bacterial contamination.3. The findings indicate that smoked fish can be contaminated by Gram-positive bacteria, such as Staphylococcus gallinarum, Staphylococcus sciuri, Rothia kristinae, and Staphylococcus pseudintermedius.

Abstract
The large marine area and abundant fish resources of Maluku Province, Indonesia, are in contrast to the poor hygiene of its traditional markets, which can cause microbial contamination and taint processed products, such as smoked tatihu (yellowfin tuna). In Ambon city, Maluku, Indonesia, no research had been conducted concerning total plate count analysis and food-contaminating bacterial identification that could guarantee the microbiological safety of smoked tatihu. Therefore, this study aimed to assess the microbiological quality of smoked tatihu according to Indonesian National Standards (INS 2725:2013) and to identify any presence of food-contaminating bacteria. This research was a quantitative descriptive study with a true experimental laboratory approach. The samples used were smoked tatihu collected from three traditional markets in Ambon, Indonesia. The spread plate method was used in the isolation process, while the total plate count analysis was performed to estimate the quantity of colonies on each petri dish. Bacterial identification was carried out macroscopically and microscopically. The microscopic identification involved Gram staining to determine the shape and color of the bacteria. Additionally, the bioMérieux VITEK 2 Compact system was utilized for biochemical identification to ascertain the species of bacteria present. The results revealed that the colony counts in smoked tatihu from the Mardika market and Hative Kecil market were 1.1 x 104 CFU/g and 8.2 x 106 CFU/g, respectively. However, smoked tatihu from the Batu Meja market had an excessive number of colonies that were difficult to quantify. The contaminating bacteria were identified as Staphylococcus gallinarum, Staphylococcus sciuri, Rothia kristinae, and Staphylococcus pseudintermedius. In conclusion, smoked tatihu fish from the Mardika market are considered safe for consumption as the microbiological parameters do not exceed the Indonesian National Standards, whereas those obtained from the Hative Kecil and Batu Meja markets are unsafe for consumption due to the excessive presence of food-contaminating bacteria.

Learning difficulties are a common issue faced by students, with stress being a significant contributing factor. One psychological treatment that has been shown to effectively reduce stress is Inquiry-Based Stress Reduction (IBSR). The objective of this study is to integrate IBSR into a discovery learning strategy in Biology in the classroom, with the aim of increasing students' learning motivation and knowledge construction while reducing their learning difficulties and cognitive anxiety. This is quasi-experimental research that used a post-test non-equivalent control group design. The study involved 72 11th-grade science students from two different classes at one of the public high schools in Bandung City. One class, consisting of 36 students, received IBSR treatment, while the other class, also consisting of 36 students, did not. Both classes used a discovery learning framework for teaching. Data on motivation, learning difficulties, and cognitive anxiety were collected using a rating scale questionnaire with eight scales. Students' ability to construct knowledge was measured using the German Cognitive Load (GCL) instrument in the form of a written test with indicators taken from Mayer's cognitive taxonomy (2002) in the realm of understanding. The study found that incorporating IBSR techniques into learning strategies for the immune system material can reduce student stress and improve learning performance, motivation, and knowledge construction (GCL), while also decreasing learning difficulties and cognitive anxiety.

Abstract

Malnutrition is a critical global public health issue that especially affects vulnerable communities. In India, traditional artisans such as Dokra artisans in the Bankura district of West Bengal are disproportionately impacted. This is the first ever study, conducted to assess the effect of secondhand smoking on the nutritional status especially chronic energy deficiency (CED) among Dokra artisans across diverse age groups. Demographic and socioeconomic data were rigorously collected, while anthropometric parameters were calculated using established formulas. A sample of 106 artisans was assessed for various anthropometric and socioeconomic parameters. The results indicated that artisans exposed to secondhand smoke had an alarming CED prevalence of 55% compared to 10.8% in those unexposed (OR = 10.022; 95% CI: 3.477–28.888). Binary logistic regression analysis further established a strong link between secondhand smoke exposure and CED (Wald = 18.209; p < 0.001) and gender (Wald = 10.121; p < 0.01), with a statistically significant overall model (χ² = 24.135; p < 0.01). Additionally, 45% of participants exposed to secondhand smoke were undernourished compared to 17.4% unexposed (OR = 3.886; 95% CI: 1.554–9.718). This research highlights critical health disparities and underscores the urgent need for targeted interventions to mitigate the adverse effects of secondhand smoke and improve the nutritional status of these artisans. Furthermore, the study identifies the economic challenges faced by the artisans, emphasizing the importance of educational and income-generating programs to promote better health outcomes and socioeconomic resilience.

Abstract

Osmotic regulation, which involves low molecular weight protectors like amino acids and phenolic compounds, is one mechanism by which agricultural crops adapt to drought. We investigated the impact of moderate soil drought on the dynamics and distribution of free amino acids, phenols, and flavonoids in 18-day-old drought-resistant plants of Triticum aestivum L. cv. 'Podolyanka' and ecologically versatile Triticum spelta L. cv. 'Frankencorn'. Moderate soil drought resulted in a 20% increase in the total free amino acid content in spelt wheat shoots, while winter wheat exhibited minimal changes. Spelt wheat shoots showed significant increases in arginine, proline, phenylalanine, cysteine, and valine, whereas winter wheat exhibited substantial increases only in phenylalanine and tyrosine. Winter wheat shoots experienced notable decreases in arginine and glutamic acid, while methionine content in spelt wheat shoots decreased. Moderate soil drought induced an increase in the accumulation of total phenols and flavonoids. Spelt wheat roots showed a substantial increase in total phenols (53%), while winter wheat exhibited a significant increase (49%) in total phenols in shoots. Total flavonoid content increased in spelt wheat shoots and roots by 17%, and 38%, respectively, under moderate soil drought, whereas in winter wheat the increase was 70% in shootsand 10% in roots. Our findings on amino acid content suggest different sensitivities of cultivars to drought stress. The moderate increase in total phenolic compounds in spelt wheat shoots underscores the sensitivity of young T. spelta cv. 'Frankenkorn' plants to water deficit, contrasting with the more drought-resistant properties observed in T. aestivum cv. 'Podolyanka'.
AI-based state extension and augmentation for nonlinear dynamical first principles models

Published: October 2024

Abstract

Nonlinear dynamics models derived using First Principles (FPs) often suffer from limited accuracy in relation to the complex physical systems they represent. Therefore, model updating may be employed to improve the accuracy of the FP model. In this work, an AI-based updating methodology is proposed where an existing FP model is extended by introducing new states (to capture, e.g., unmodeled modes or parasitic degrees of freedom) using a subspace encoder, and capture their governing equations of motion using a Recurrent Neural Network (RNN). Additionally, the retained FP equations of motion are augmented by additional RNNs to capture unmodeled dynamics (e.g. nonlinearities) or improper parameter values. Simultaneously training all neural networks such that an output prediction error-based loss is minimized yields an Extension and Augmentation-based (EA) model that significantly decreases the prediction error with respect to the FP model. This methodology is applied on two use cases, one of which uses measurements performed on an industrial wire bonder. These use cases demonstrate that, also when changes are made to the FP parameters, excitation signals, and controllers, the EA model still shows significant improvement in prediction capability over the FP model. This shows that by using the FP model as a basis for model updating, the extrapolation capabilities of the resulting model are improved. Furthermore, the EA model updating method is compared with a similar, yet fully black-box, subspace-encoder network method. The EA model is shown to outperform such purely data-based models in terms of accuracy, training efficiency, and extrapolation capabilities. Finally, in contrast to the (purely data-based) subspace-encoder network method, the EA model updating method enables updating of unstable open-loop systems by embedding stabilizing controllers in the FP model.

Abstract

This article reports the preparation, analytical, and thermoluminescence (TL) characterization of BaTi5O11 doped with different concentrations of Ce. The Sol-gel technique was used to synthesize the doped nanocrystals. The prepared samples were examined by XRD, EDX, UV-Vis spectrophotometry, SEM, and TEM techniques to determine their analytical features. The samples with 0.7% Ce doping showed the highest TL sensitivity for ionizing radiation among the samples prepared with different concentrations. The glow curves analysis showed that there were seven peaks that overlapped with each other with thermal activation energies: 0.93, 1.08, 1.16, 1.23, 1.29, 1.35, and 1.38 eV. The dose-response linearity and reusability measurements displayed that 0.7% Ce-doped BaTi5O11 can be used in monitoring high doses radiation applications.

Abstract

The lack of terahertz (THz) components and strong THz diffraction limit greatly THz wavefront-phase manipulation. This paper introduces a universal and versatile THz wavefront-phase manipulation mechanism through a double Pancharatnam-Berry (PB) phase-based dislocation scheme at near-infrared (NIR) region, avoiding the need of THz components while mitigating effectively the adverse effect of THz diffraction. The mechanism bases on an innovative NIR light-field manipulation mechanism enabling independent controls of two wavefront-phases by two-dimensional (2D) dislocations of two phase-plates with conjugated phase functions. Independence is ensured as long as the partial derivatives of the target phase pair with respect to the spatial variables are equal—a condition satisfied by numerous important phase pairs, such as logarithmic-axicon versus vortex phases (for Bessel and vortex beams) and one-dimensional (1D) versus 2D cubic phases (for 1D and 2D Airy beams). Notably, for only one target wavefront, it is applicable to any kinds of phases. To realize the NIR manipulation, a novel dislocation scheme is further designed with two PB plates as the conjugated phase-plates, which not only enables the NIR manipulation but also produces a pair of collinear pulses with conjugated modulated phases and orthogonal polarizations. By using the pulse pair as the pumps, the dislocation scheme can transfer the wavefront-phase manipulation from NIR to THz region by type-II difference frequency generation. Finally, a proof-of-principle experiment successfully presents the flexible realization of this dislocation scheme for multiple wavefront-phase manipulation at NIR and exhibits its ability to dynamically generate and control THz vortex, Bessel, and vortex-Bessel fields with adjustable topological charge and “diffraction-free” propagation distances. This work offers a flexibly way for universal and versatile manipulation, especially where direct phase manipulation is practically restricted, especially in THz region.
Uncovering the onset and progression of ferroptosis via live-cell imaging

Published: October 2024

Abstract

Ferroptosis is a form of non-apoptotic cell death involving formation of lipid peroxyl radicals with potential therapeutic applications. Intracellularly, sensitivity to ferroptosis is expected to differ based on the distribution of enzymes, metabolites, small molecule regulators and inducers. However, spatial-temporal information, necessary to understand the intricacies of subcellular membranes in ferroptosis, is currently missing. Here we designed organelle-targeting, lipophilic fluorogenic lipid peroxyl radical probes—radical trapping antioxidants (fluorogenic RTAs)—to monitor real-time the onset and progression of lipid peroxidation in ferroptosis. Working with HT-1080 cells and the canonical ferroptosis inducer RSL3, imaging peroxyl radicals, while simultaneously monitoring cell rounding and membrane permeability, indicate that lipid peroxyl radical production is characterized by an initial—organelle and RSL3 concentration dependent—induction or runaway period. This period is followed by a steady generation of lipid peroxyl radicals. The onset of lipid peroxidation occurs faster in the ER region than in the other organelles, yet the steady rate of progression is similar in all subcellular membranes explored. Here the ER- and lysosomes-embedding RTAs, and to a lesser extent the mitochondria, are more effective in protecting from cell rounding/death, compared to the PM-embedding RTA. This indicates that antioxidant protection, while vital at the internal membranes, plays a minor role at the PM. High-resolution single-cell imaging and colocalization studies show for the ER-embedding RTA, lipid hydroperoxide generation and/or accumulation initially in structures adjacent to the Golgi apparatus resembling the ER-Golgi intermediate compartment (ERGIC), followed by their late transport through the endomembrane system to plasma membrane. These results suggest Golgi-associated vesicles are initially acting as reservoirs of newly peroxidized lipids, which subsequently spread to other organelles effectively acting as “free radical embers.” In addition, single-cell imaging with the mitochondria, lysosomes, or PM-targeting RTA revealed that oxidized lipids are trafficked unidirectionally from internal membranes to plasma membrane, making the latter the ultimate sink for oxidized lipids. Lethal internal membrane damage occurs early in ferroptosis, where plasma membrane protection to lipid peroxidation shows little impact in overall cell survival. These results underscore Golgi-associated structures as the key organelle involved in accumulating lipid hydroperoxides early in ferroptosis, providing a putative target to regulate ferroptosis progression. The work further positions fluorogenic RTAs as valuable tools for unravelling the dynamic, subcellular progression of ferroptotic cell death for different cell lines and ferroptosis inhibitors and inducers.
