EXPLORANDO O POTENCIAL DO CRAJIRU PARA UM TINGIMENTO SUSTENTÁVEL DE TECIDOS DE ALGODÃO COM PROTEÇÃO UV

Objective: The objective of this study is to investigate the potential of using crajiru leaves as a natural dye for cotton fabrics. Theoretical Framework: This section presents the main concepts and theories underpinning the research. Key theories include natural dyeing, the chemistry of natural dyes, dye extraction methods, and the theory of adsorption on textile substrates, providing a solid foundation for understanding the research context. Method: The methodology adopted for this research comprises an experimental study, including dye extraction, fabric dyeing, and the evaluation of fastness and UV protection. The materials used include dried crajiru leaves, chitosan, acetic acid, non-ionic detergent, temperature control equipment, and dyeing machines. Data collection was carried out through direct observations of the extraction and dyeing processes, as well as laboratory tests to measure extraction efficiency, dye yield, wash fastness, and UV protection. Results and Discussion: The results revealed that higher temperatures led to greater efficiency in extracting the dye from crajiru leaves. The fabric dyeing process showed that higher temperatures resulted in better dye yield. Pre-treatment of the fabrics with chitosan significantly increased the absorption of the dye by cotton fibers, improving dye yield. Wash fastness tests indicated that the dyed fabrics maintained good fastness properties. The UV protection assessment showed that the crajiru extract promoted high UV protection, especially in samples pre-treated with chitosan. In the discussion section, these results are contextualized in light of the theoretical framework, highlighting the implications and identified relationships. Possible discrepancies and limitations of the study are also considered in this section. Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results can be applied or influence practices in the field of sustainable textile technology. These implications may cover the sustainable fashion industry, the development of new textile products, and the improvement of natural dyeing processes. Originality/Value: This study contributes to the literature by investigating the use of crajiru leaves as a natural dye for cotton fabrics, highlighting the influence of temperature and chitosan pre-treatment. The originality of the research lies in the innovative approach of combining chitosan with the natural dyeing process and new findings related to extraction efficiency and UV protection. The relevance and value of this research are evidenced by its potential impact on the textile industry, promoting more sustainable and environmentally responsible processes.Objetivo: O objetivo deste estudo é investigar o potencial do uso de folhas de crajiru como corante natural em tecidos de algodão.   Referencial Teórico: São apresentados conceitos sobre tingimento natural, química dos corantes, métodos de extração e teoria de adsorção em substratos têxteis, fornecendo base para a investigação.   Método: O estudo experimental inclui a extração do corante, tingimento dos tecidos e avaliação de solidez e proteção UV.

METHODS: Patients from Rheumatic Diseases Portuguese Register (Reuma.pt) with a clinical diagnosis of axial spondyloarthritis (axSpA) were included. Four subgroups (cross-tabulation between ASDAS (≥2.1) and BASDAI (≥4) definitions of high disease activity) were compared regarding baseline characteristics and response to bDMARDs at 3 and 6 months estimated in multivariable regression models. RESULTS: Of the 594 patients included, the majority (82%) had both BASDAI≥4 and ASDAS ≥2.1. The frequency of ASDAS ≥2.1, if BASDAI<4 was much larger than the opposite (ie, ASDAS <2.1, if BASDAI≥4): 62% vs 0.8%. Compared to patients fulfilling both definitions, those with ASDAS ≥2.1 only were more likely to be male (77% vs 51%), human leucocyte antigen B27 positive (79% vs 65%) and have a higher C reactive protein (2.9 (SD 3.5) vs 2.1 (2.9)). Among bDMARD-treated patients (n=359), responses across subgroups were globally overlapping, except for the most 'stringent' outcomes. Patients captured only by ASDAS responded better compared to patients fulfilling both definitions (eg, ASDAS inactive disease at 3 months: 61% vs 25% and at 6 months: 42% vs 25%). CONCLUSION: The ASDAS definition of high disease activity is more inclusive than the BASDAI definition in selecting patients with axSpA for bDMARD treatment. The additionally 'captured' patients respond better and have higher likelihood of predictors thereof. These results support using ASDAS≥2.1 as a criterion for treatment decisions.publishersversionpublishe

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states

Consistent patterns of common species across tropical tree communities

Trees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge. Here we investigate abundance patterns of common tree species using inventory data on 1,003,805 trees with trunk diameters of at least 10 cm across 1,568 locations1,2,3,4,5,6 in closed-canopy, structurally intact old-growth tropical forests in Africa, Amazonia and Southeast Asia. We estimate that 2.2%, 2.2% and 2.3% of species comprise 50% of the tropical trees in these regions, respectively. Extrapolating across all closed-canopy tropical forests, we estimate that just 1,053 species comprise half of Earth’s 800 billion tropical trees with trunk diameters of at least 10 cm. Despite differing biogeographic, climatic and anthropogenic histories7, we find notably consistent patterns of common species and species abundance distributions across the continents. This suggests that fundamental mechanisms of tree community assembly may apply to all tropical forests. Resampling analyses show that the most common species are likely to belong to a manageable list of known species, enabling targeted efforts to understand their ecology. Although they do not detract from the importance of rare species, our results open new opportunities to understand the world’s most diverse forests, including modelling their response to environmental change, by focusing on the common species that constitute the majority of their trees.Publisher PDFPeer reviewe

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Associação entre a ooforectomia bilateral precoce e o desenvolvimento do parkinsonismo e Doença de Parkinson em mulheres na pré-menopausa

O parkinsonismo é um distúrbio do sistema nervoso de maior incidência masculina do que feminina, visto que, por mecanismos fisiológicos, o estrogênio possui efeitos neuroprotetores, com funções como aumento da dopamina, um neurotransmissor essencial para o controle das funções motoras. Além disso, previne a formação dos corpúsculos de Lewy e da agregação da α-sinucleína, responsáveis pela progressão da Doença de Parkinson. Por isso, a doença se apresenta diferentemente nas mulheres. A remoção cirúrgica de ambos os ovários em mulheres na pré-menopausa para a prevenção do câncer de ovário parece favorecer o surgimento da doença, tendo em vista a perda da produção do hormônio protetor. Assim, o objetivo do estudo é analisar a associação entre a ooforectomia bilateral precoce e o desenvolvimento de parkinsonismo e Doença de Parkinson em mulheres na pré-menopausa. Trata-se de uma revisão bibliográfica sistemática, do tipo quantitativa, que utilizou as plataformas do PubMed, SciELO e Cochrane Library como bases de dados para seleção dos artigos, todos na língua inglesa. Foram utilizadas literaturas publicadas com recorte temporal de 2017 a 2022. De acordo com as literaturas analisadas, a ooforectomia bilateral precoce em mulheres na pré-menopausa aumenta o risco do desenvolvimento de parkinsonismo. Desse modo, a diminuição dos procedimentos cirúrgicos profiláticos para câncer de ovário nas pacientes com risco médio de malignidade reduziria o risco dessa condição

The psychological science accelerator’s COVID-19 rapid-response dataset

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data

In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., "If you do not practice these steps, you can endanger yourself and others") or potential gains (e.g., "If you practice these steps, you can protect yourself and others")? Collecting data in 48 languages from 15,929 participants in 84 countries, we experimentally tested the effects of message framing on COVID-19-related judgments, intentions, and feelings. Loss- (vs. gain-) framed messages increased self-reported anxiety among participants cross-nationally with little-to-no impact on policy attitudes, behavioral intentions, or information seeking relevant to pandemic risks. These results were consistent across 84 countries, three variations of the message framing wording, and 560 data processing and analytic choices. Thus, results provide an empirical answer to a global communication question and highlight the emotional toll of loss-framed messages. Critically, this work demonstrates the importance of considering unintended affective consequences when evaluating nudge-style interventions
