Authors: Santos Raissa , de Lima Santos Leandro , Manoel Moraes de Camargo Almeida Luiz , Carmona Duval Henrique
Published: May 2024

Iniciativas em políticas públicas de segurança alimentar se tornaram mais proeminentes no Brasil no final do século XX, especificamente envolvendo ações de amparo à produção e consumo como a Política de Garantia de Preços Mínimos (PGPM), que busca a partir de diversos instrumentos equilibrar preços à partir de subsídios e estoques públicos, com vistas à estabilidade do abastecimento. No entanto, a discrepância entre os valores pagos aos produtores e os praticados no mercado pode afetar sua eficácia. A pandemia de COVID-19 acentuou os aumentos de preços, impactando consumo de alimentos fundamentais. Este estudo abordou as flutuações de mercado de produtos essenciais na cesta básica brasileira de 2019 a 2022, avaliando a ação estatal via PGPM na mitigação de impactos na renda dos produtores e no consumo familiar. Utilizando análises descritivas e exploratórias, revelou discrepâncias entre os preços recebidos pelos produtores e os praticados nos mercados, destacando a negligência governamental, evidenciada na diminuição das atividades da Companhia Nacional de Abastecimento (Conab) ao longo do tempo. A ausência de investimento na reserva estratégica de alimentos expõe a fragilidade do Estado, indicando a necessidade de políticas mais abrangentes para assegurar estabilidade econômica e acesso adequado aos alimentos básicos, especialmente, em períodos de crise como durante a pandemia. O estudo sugere a urgência de reflexões e debates para desenvolver estratégias mais eficazes de abastecimento alimentar, como parte do compromisso estatal de garantia do Direito Humano à Alimentação Adequada (DHAA).

Published: May 2024

The present study report the development of an amplified fragment length polymorphism (AFLP)-derived sequence characterized amplified region (SCAR) marker for reliable identification of Njavara (Oryza sativa landrace Njavara), a rice landrace in India used extensively in health foods and Ayurveda treatments. The SCAR locus, named OsNSCAR131 after O. sativa landrace Njavara, is located on chromosome 3 between nucleotide positions 7793982 and 7794108, and yields a 131-bp allele in Njavara accessions and a 127-bp allele in other rice cultivars due to a 4-bp Insertion-Deletion (InDel) mutation at nucleotide position 7794026. We standardized the SCAR assay to be like those used for detecting microsatellite markers by using fluorescently (6-FAM) labeled primers and separating the alleles by capillary electrophoresis. As an alternative, we further adapted the method so as to allow allele detection by polyacrylamide gel electrophoresis (PAGE). A single rice grain can be tested for authentication by this PAGE assay. The SCAR marker developed here has great utility in authenticating Njavara grains in both the health food and pharmaceutical sectors.
Using the Practical Indigenous Knowledge System to Teach Genetics and Evolution: Narratives by South African Life Sciences Teachers
Authors: Teane Florah
Published: May 2024

The traditional methods of teaching the life sciences topics of evolution and genetics have proven without doubt that they did not scratch the surface towards enhancing teachers’ ability to effectively deliver the content knowledge. Such evidence is found in the internal moderators’ reports issued annually after the marking of life sciences Grade 12 examination papers, which indicate poor learner performance in the two topics. The study that informed this article explored the transformative potential of integrating the community indigenous knowledge system to enhance learners’ understanding of difficult life sciences topics, such as evolution and genetics. There have been shared concerns by all stakeholders in education about learners’ continual underperformance in life sciences, regardless of the endless lists of interventions to address content gaps. This study aimed to apply the current indigenous knowledge practised by the local community to not only create a more holistic understanding of evolution and genetics, but also to show the role that learners’ prior knowledge can play during teaching and learning. In the study, a qualitative research approach with purposeful sampling was used. Data were collected through individual interviews, focus group interviews, document analysis, and observation. Teachers from 20 secondary schools participated in this research. Collected data were analysed using Creswell’s method of coding. The findings of this study indicate that using the indigenous knowledge system helped to equip teachers with a transformative approach to teaching problematic life sciences topics, which ultimately resulted in improved learner performance. The findings of this research can have significant implications for teachers, policymakers and researchers seeking innovative ways to enhance science education and promote cultural diversity.

Entretanto, apesar dos avanços, a realidade ainda enfrenta barreiras que demandam atenção e ação contínua.
Diagnostic significance of clay-like materials aspirated from thyroid nodules
Authors: Kanematsu Risa , Hirokawa Mitsuyoshi , Suzuki Ayana , Higuchi Miyoko , Miyauchi Akira , Akamizu Takashi
Published: May 2024

Objective:

The simplest way to determine the adequacy of aspirated materials is the on-site gross visual assessment of aspirated materials. However, few studies have examined the gross findings of thyroid aspirates. This study aimed to clarify the diagnostic significance of clay-like material aspirated from thyroid nodules.

Material and Methods:

We reviewed 69,848 thyroid nodules that underwent aspiration cytology at Kuma Hospital between January 2007 and August 2021. Among them, 355 (0.5%) nodules with aspirated materials described as clay-like materials were retrospectively examined.

Results:

Among 355 nodules, 322 (90.7%) were categorized as cystic fluid or benign. The aspirated materials were mainly composed of non-epithelial components, including colloid or proteinaceous materials, foamy histiocytes, and degenerative red blood cells. In original ultrasound reports, the incidence of intermediate and high suspicion was 11.0%. Malignant cells were observed in 21 nodules (5.9%), one-third of which were papillary thyroid carcinomas. The materials aspirated from papillary and follicular thyroid carcinomas exhibited necrotic carcinoma cells derived from infarcted areas. The overall risk of malignancy was 3.9%. The risk of malignancy in nodules interpreted as highly suspicious on ultrasound examination was 37.5%.

Conclusion:

As clay-like materials aspirated from thyroid nodules were considered sufficient specimens, the recognition contributes to avoiding unnecessary second punctures. The presence of clay-like materials was indicative of the colloid and/or blood components of benign cystic lesions, or, more rarely, of infarcted carcinoma. The ultrasound examination results tended to overestimate nodules. We should reaffirm that on-site gross visual assessment of aspirated materials is a fast and reasonably accurate predictor of the on-site adequacy of the samples.

Authors: Azwar Mina , Shafqat Anam , Fatima Mahnoor , Ijaz Farhat , Naseem Rahat , Aftab Rana Khurram
Published: May 2024

Objectives:

Procrastination is the deliberate delay or postponement of tasks with an awareness of unfavorable results. Revenge bedtime procrastination refers to the choice of forgoing sleep in favor of leisure time due to a daily schedule devoid of adequate free time. The objective of this study was to determine the correlation between revenge bedtime procrastination and academic performance in undergraduate medical students.

Material and Methods:

The participants in this study were medical students from different institutes in Lahore. A total of 239 participants completed our online survey. Students previously diagnosed with sleep disorders were excluded from our sample. Our study, which centeredon exploring the correlation between bedtime procrastination as a retaliatory act and academic achievement, employed an online questionnaire containing the academic performance scale (APS) and bedtime procrastination scale (BPS) disseminated through Google Forms.

Results:

The findings demonstrated a negative correlation between delaying sleep for personal leisure time and academic achievement. The correlation coefficient (R) value between APS and BPS came out to be −0.324, and the P value was 0.01, which means that the relationship is statistically significant. The major demographics came out to age 15–20 years (72.4%) studying Bachelor of Medicine and Bachelor of Surgery (87.2%) and Bachelor of Dentistry (10.9%), and the majority of them were in the 1st (37.6%) and 2nd year 51.9% of their degree.

Conclusion:

This study found a negative correlation between sleep procrastination and academic performance. Variables such as intelligence, motivation, and self-discipline were not considered in our study, and this gap can be filled by future research considering additional variables to gain a more comprehensive understanding of this complex phenomenon.
Assessment of Nurses’ Knowledge, Attitude and Practice Regarding Physical Restraint: A Scoping Review
Authors: Alsomali Zahra , Elsayes Hala Ahmed , Sharif Loujain Saud
Published: May 2024

The use of physical restraints (PR) in healthcare settings, especially in psychiatric units, is a controversial topic. The attitude, knowledge, and practices of nurses towards PR can influence its application, which raises concerns about the balance between patient safety and individual rights. With mental disorders being a leading cause of disability globally, understanding the complexities surrounding PR use becomes paramount. A comprehensive literature review was conducted using multiple databases, including PubMed, Medline, CINAHL, PsycINFO, ProQuest, The Cochrane Library, the Saudi Digital Library, and Google Scholar. The search spanned literature published up to December 2022, focusing on studies that explored the relationship between nurses’ knowledge, attitudes, and practices regarding PR in psychiatric settings. Inclusion and exclusion criteria were applied to filter out relevant studies. From 220 records initially retrieved, 12 articles were identified for the final review. The reviewed studies highlighted a moderate knowledge and attitude among nurses concerning PR. Many nurses were found to be uncertain about the reasons for PR application and its alternatives. Educational interventions were emphasized in several studies as beneficial in improving nurses’ knowledge, attitudes, and practices. However, inconsistencies were observed regarding the impact of these interventions on nurses’ attitudes. Experience, higher education, and continuous training sessions were found to be correlated with better knowledge and more favourable attitudes towards PR. This review emphasizes the critical need for consistent training and education for nurses regarding PR, given the profound implications for patient care and safety. While educational interventions show promise in enhancing knowledge and practice, their impact on attitudes remains contested. Future research should consider the gaps identified in this review, including the exploration of alternatives to PR, larger sample sizes and longitudinal studies to understand the long-term effects of interventions.

Authors: Jounaidi Khaoula , Hamdoune Meryem , Daoudi Khadija , Barka Najwa , Gantare Abdellah
Published: May 2024

Objectives:

This study addresses the growing demand for palliative care (PC) by exploring the role of advanced nursing practice (ANP) within the multidisciplinary team. The purpose is to outline the background of ANP in PC, its interest, training needs, and some recommendations for its establishment in the Moroccan healthcare system.

Materials and Methods:

A rapid review of relevant studies was carried out through databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards, edition (2020). The inclusion criteria focussed on studies published within the nursing domain between 2012 and 2022, with a preference for the English language.

Results:

Study selection allowed to obtain eight relevant studies. The studies agreed that ANP improves the quality of care provided. It has a major role to play in the multidisciplinary team by mobilising all the knowledge required to offer a complete range of care for patients with needs. Nevertheless, its implementation is fraught with challenges.

Conclusion:

ANP will be able to address the complexity of patient and family needs and serve as cost-effective medical care coordinators for patients and families with both chronic and life-limiting illnesses, to reduce suffering and improve the quality of living and dying across the lifespan. Advanced practice nurses execute assigned authorisations by mobilising the knowledge acquired through university training. The establishment of this cadre in the healthcare system is subject to many challenges that Morocco must anticipate.
Computational Screening of Putative Catalyst Transition Metal Complexes as Guests in a Ga4L6–12 Nanocage
Authors: Reinhardt Clorice , Manetsch Melissa , Li Wanlu , Head-Gordon Teresa , Kulik Heather
Published: May 2024

Metal-organic cages form well-defined microenvironments that can enhance the catalytic proficiency of encapsulated transition metal catalysts (TMCs). We introduce a screening protocol to efficiently identify TMCs that are promising candidates for encapsulation in the Ga4L6-12 nanocage. We obtain TMCs from the Cambridge Structural Database with geometric and electronic characteristics amenable to encapsulation and mine the text of associated manuscripts to curate TMCs with documented catalytic functionality. By docking candidate TMCs inside the nanocage cavity and carrying out electronic structure calculations, we identify a subset of successfully optimized candidates (TMC-34) and observe that encapsulated guests occupy an average of 60% of the cavity volume, in line with previous observations. Notably, highly charged guests occupy as much as 72% of the cavity as a result of linker rotation. Encapsulation has a universal effect on the electrostatic potential, systematically decreasing the electrostatic potential at the metal center of each TMC in the TMC-34 dataset, while minimally altering TMC metal partial charges. Collectively these observations support geometry-based screening of potential guests and suggest that encapsulation in Ga4L6 cages could electrostatically stabilize diverse cationic or electropositive intermediates. We highlight candidate guests with associated known reactivity and solubility most amenable for encapsulation in experimental follow-up studies.
Different Nucleation Mechanisms during Atomic Layer Deposition of HfS2 on Cobalt Oxide Surfaces
Authors: Fickenscher Georg , Sidorenko Nikolai , Mikulinskaya Kira , Libuda Joerg
Published: May 2024

We investigated the atomic layer deposition (ALD) of HfS2 on atomically defined CoO(100) and CoO(111) surfaces under ultrahigh-vacuum (UHV) conditions. The ALD process was performed by sequential dosing of the precursors tetrakis(dimethylamido)hafnium (TDMAH) and deuterium sulfide (D2S) separated by purging periods. The growth and nucleation reactions were monitored by in situ infrared reflection absorption spectroscopy (IRAS). HfS2 films nucleate and grow on both cobalt oxide surfaces, despite the fact that CoO(100) lacks acidic protons and CoO(111) exposes only very few OH groups at defects. On these OH- free or OH-lean surfaces, the nucleation step involves a Lewis acid-base reaction instead. The stoichiometry of the –Hf(NMe2)x nuclei changes during the first ALD half cycle. On CoO(100), the split-off ligands bind as –NMe2 to surface cobalt ions. The nucleation on CoO(111) is more complex and the split-off ligands undergo dehydrogenation to form various surface species with C=N double and C≡N triple bonds and surface OH. Our findings reveal a new nucleation mechanism for ALD in the absence of acidic protons and show that other factors such as Lewis acidity, surface structure, and surface reactivity must also be considered in the nucleation event.
Solution characterization of zirconium oxo clusters

Published: May 2024

Group 4 metal oxo clusters are atomically precise models for colloidal nanocrystals as they consist of an inorganic core and an organic ligand shell. They are also important building blocks for MOFs, 3D-printing and polymers composites. Recently, we have elucidated their structure and ligand shell using solid state methods. Here we go one step further studying these materials in solution. Dynamic light scattering is a common technique to determine the solvodynamic diameter of nanocrystals. However, due to their small size, clusters present difficulties to the automatic data treatment, available in commercial software. Here we developed a data treatment method to fit DLS data of clusters, where we separate the signal into a contribution from the clusters itself combined with a contribution of number fluctuations. Additionally, diffusion ordered spectroscopy (DOSY) is used to study how these materials affect the viscosity of the solvent.

Octacalcium phosphate (OCP, Ca8(PO4)4(HPO4)2.5H2O) is a notable calcium phosphate due to its biocompatibility, making it a widely studied material for bone substitution. It is known to be a precursor of bone mineral, but its role in biomineralisation remains unclear. While the structure of OCP has been the subject of thorough investigations (including using Rietveld refinements of X-ray diffraction data, and NMR crystallography studies), important questions regarding the symmetry and H-bonding network in the material remain. In this study, it is shown that OCP undergoes a lowering of symmetry below 200 K, evidenced by 1H, 17O, 31P and 43Ca solid state NMR experiments. Using ab-initio molecular dynamics (MD) simulations and Gauge Including Projected Augmented Wave (GIPAW) DFT calculations of NMR parameters, the presence of rapid motions of the water molecules in the crystal cell at room temperature is proved. This information leads to an improved description of the OCP structure at both low and ambient temperatures, and helps explain long-standing issues of symmetry. Remaining challenges related to the understanding of the structure of OCP are then discussed.
Electrostatically-enriched Lithium Cations Catalyze Biomimetic Aerobic Oxygenation

Published: May 2024

Enzymes often involve short-range electrostatic interactions in the deliberate microenvironment for accelerating the catalysis. Comparatively, electrostatic interactions from ions in solutions are mostly shielded by solvent or counter-ion shells, creating negligible catalytic effects. Herein, we discovered that the Li+ cations electrostatically accumulated on negatively-charged carboxylated carbon nanotubes could create strong interactions with in-situ formed peroxide anion (OOH-) intermediates from O2 reduction, forming an active side-on Li+-OOH- complex. This complex reduces the O2-reduction energy barrier and increases the nucleophilicity, expediting the aerobic oxygenation of ketones. Aside from trapping active intermediates, excessive Li+ cations also attract the surrounding water dipoles to prevent from quenching the active Li+-OOH- complex, highly mimicking the Baeyer Villiger monooxygenase (BVMO). By using probe-assisted quantitative methods, we demonstrated the unique under-coordinative characteristics of interfacial Li+ with an order of magnitude higher concentration than the bulk solution, providing essential clues about the intrinsic discrepancy between electrocatalytic and thermocatalytic reactivities.

A μ-peroxido-bis[di-triethylamine N-oxide-dichlorodioxouranium] complex with the formula [(UO2)2O2(ON(CH3)3)4Cl2] (complex 1) was synthesized photochemically from a reaction containing uranyl chloride, triethylamine, and H2O2. The photochemical breakdown of H2O2 yielded •OH radicals that reacted with triethylamine to form triethylamine N-oxide (TEAO) in situ, which subsequently coordinated to UO22+ cations in a monodentate fashion via the N-oxide functional groups. Structure determination using single crystal X-ray diffraction revealed that TEAO ligands also formed intermolecular and intramolecular hydrogen bonds with UO22+ and peroxide moieties, and the intermolecular H-bonding interactions displayed a temperature dependence with Oyl - - H – C and Oper - - H – C distances shortening at 100(2) K by ca. 0.1 Å. Additional coordination in the equatorial plane of complex 1 includes chloride ligands that are bound to each UO22+ cation in a trans orientation and an η2 : η2 μ2 peroxide (O22-) ligand connects the two UO22+ cations in a bent configuration. Raman spectroscopy data were collected on single crystals of 1 and peak fitting of these results allowed for assignments of peaks including C-N stretches for TEAO ligands bound to UO22+ cations at 696.8 cm-1, 717.8 cm-1, and 776.5 cm-1, which are redshifted by approximately 30 cm-1 when compared to free triethylamine. UO22+ ν1 and O22- ν1 stretches, U-Oper stretches, and notably, U-Cl stretches were all identified as well, with U-Cl modes at 198.9 cm-1 and 212.1 cm-1 substantially redshifted compared to the uranyl chloride starting material.
The SCEC/USGS Community Stress Drop Validation Study Using the 2019 Ridgecrest Earthquake Sequence

Published: May 2024

We introduce a community stress drop validation study using the 2019 Ridgecrest, California, earthquake sequence, in which researchers are invited to use a common dataset to independently estimate comparable measurements using a variety of methods. Stress drop is the change in average shear stress on a fault during earthquake rupture, and as such is a key parameter in many ground motion, rupture simulation, and source physics problems in earthquake science. Spectral stress drop is commonly estimated by fitting the shape of the radiated energy spectrum, yet estimates for an individual earthquake made by different studies can vary hugely. In this community study, sponsored jointly by the U. S. Geological Survey and Southern/Statewide California Earthquake Center, we seek to understand the sources of variability and uncertainty in earthquake stress drop through quantitative comparison of submitted stress drops. The publicly available dataset consists of nearly 13,000 earthquakes of M1 to 7 from two weeks of the 2019 Ridgecrest sequence recorded on stations within 1-degree. As a community study, findings are shared through workshops and meetings and all are invited to join at any time, at any interest level.
Amplifying Whitness and Teaching as Being With

Hansen, D. T. (2021). Reimagining the call to teach: A witness to teachers and teaching. Teachers College Press.
David Hansen’s book Reimaging the Call to Teach: A Witness to Teachers and Teaching, in very nuanced, subtle, and complicated ways, inquires into teaching as a calling: it enacts and embodies the educational moments and space in teaching filled with uncertainties and complexities as “being with” (p. 33) others, “linking the past, present and future” (p. xiii). Hansen, as it rarely happens, bears an attuned and amplifying witness in sitting in on the classrooms as well as ongoing conversions to 16 public teachers over 2 years who participated in the “Person Project” (p. 52), which assembles teachers’ testimonials about teaching and what it means to “be a person in the world today” (p. 54) without imposing objectifying measurements and standards. In the book, the messy and rough ground of teaching, full of feelings, hesitations, and confusions, is not analyzed and decoded but rather felt, embodied, and described more comprehensively. As Hansen suggests, “I believe what is put forward here is a better description of the unity of the aesthetic, ethical, moral, and intellectual aspects of teaching—of the gestalt of teaching—of the meaning of teaching” (p. 57).

Para o estudo de estereoisômeros no nível médio, acredita-se que seja necessária a implementação de estratégias que facilitem o desenvolvimento de habilidades visuoespaciais e sociais cooperativas. Para tanto, uma Sequência Didática utilizando o método Jigsaw, foi desenvolvida para uma turma de 3º ano do ensino médio de uma escola pública da periferia de Fortaleza-CE. A aprendizagem cooperativa em seu método Jigsaw é uma metodologia ativa baseada na participação coletiva dos estudantes. Ela é aplicada geralmente para pequenos grupos, de forma a possibilitar o desenvolvimento cognitivo, através da troca de informações e de habilidades. Para coleta de dados qualitativos da pesquisa, foram aplicados: protocolo de observação, questionários e gravações de vídeos.  A estratégia didática foi desenvolvida nas etapas de: atividade virtual sobre aprendizagem cooperativa e método Jigsaw; aplicação do método Jigsaw e construção de modelos moleculares; aplicação de questionário avaliativo. Também foram analisadas respostas provenientes de: uma avaliação pedagógica coletiva, questionários de processamento de grupo e de opiniões (escala Likert). Com a aplicação do método Jigsaw, percebeu-se que os alunos trabalharam de forma coletiva, solidária, colaborativa e ativa, interagindo e compartilhando suas ideias, desenvolvendo habilidades sociais e visuoespaciais a partir da construção de modelos moleculares, contribuindo significativamente para o processo de ensino e aprendizagem de conceitos básicos de estereoisomeria.

O texto traz uma atividade envolvendo escolas de educação básica do município de Uruguaiana participantes de um projeto de extensão. O referido projeto constituiu-se em um jogo de perguntas e respostas em grupo, em que os alunos disputaram a competição em seu respectivo nível de ensino, fundamental ou médio. Cada escola respondia quinze perguntas, das áreas de Ciências da Natureza, Ciências Sociais, Língua Portuguesa e Literatura Brasileira, Raciocínio Lógico e Conhecimentos Gerais, com três diferentes níveis de dificuldade, de nível fácil ao difícil. O jogo veio como uma proposta de trazer a avaliação de uma forma lúdica ao estudante. Conforme relatos dos participantes, o jogo mostrou-se uma ferramenta diferenciada e menos pressionadora de avaliar as aprendizagens. Também procurou-se desenvolver o jogo em uma ferramenta de fácil manuseio pelos educadores, de maneira que ele próprio, sem conhecimentos aprofundados de programação de computadores, possa criar seus materiais didáticos conforme sua imaginação e necessidades.

The article deals with the issues of increasing the risk of sports trauma and its rehabilitation, which is determined by the factor of active participation in training and competitive activities of children and adolescents. The authors of the research emphasize the increased traumatic danger of contact, power, game and extreme sports, at the same time, the tendency of increase of injuries and damages of the musculoskeletal system at a young age, previously characteristic for mature athletes, is noted. At the same time, the analysis of scientific literature sources has determined the importance of medical rehabilitation, the importance of using physical rehabilitation means, their combinations and combinations in the recovery period. The relevance of the present research is determined by the need to find a set of physical rehabilitation means in combination with the medical component, which will provide potentiation of the rehabilitation effect through the polyeffector principle. The aim of the work is to determine the effectiveness of physical rehabilitation complexes for school-age children with sports injuries of the shoulder girdle and free upper extremity at the postimmobilization stage of rehabilitation treatment. The analysis of the obtained data characterizes the effectiveness of application of physical rehabilitation complexes in combination with physiotherapeutic procedures, and a more pronounced effect of application of physical rehabilitation complexes in children of the main group, relative to the control group, was noted. The method of deep reflex-muscular massage, in combination with therapeutic gymnastics and physiotherapy procedures, causes the activation of the mobilization of the body's natural forces, which was reflected in the potentiation of the effectiveness of the application of the physical rehabilitation complex developed for children of the main group with sports injury at the postimmobilization stage of the recovery period.
