title: Perspectives and challenges on isotopic ecology of terrestrial birds in Brazil

description: ABSTRACT Although stable isotopes have been increasingly used in ornithology since 1980 in many places, Brazil has been slow in adopting this methodology, especially when it comes to terrestrial birds. The most common elements in bird ecology studies are carbon, nitrogen, hydrogen, and oxygen stable isotopes, which provide information on diet, trophic interactions, habitat use, migration, geographic patterns, and physiology. It is important that Brazilian ornithologists become aware of the potential of stable isotope analysis in ecological studies, and the shortcomings of this tool. The use of stable isotopes to study bird ecology has great potential in Brazil, since many ecological questions about Neotropical birds can be addressed by it (e.g., resource and habitat use, migratory routes, isotopic niches, anthropogenic impacts, individual specialization). Brazilian museums and other Natural History collections can provide samples to study long-term temporal dynamics in bird ecology. Additionally, the integration of avian tissue sample information into a database may increase the collaboration among researchers and promote sample reuse in a variety of studies. All biomes in Brazil have been under pressure from anthropogenic impacts (e.g., land-use change, habitat loss, fragmentation, intensive agriculture), affecting several taxa, including terrestrial birds. Considering the negative effects of human expansion over natural areas and that stable isotopes provide useful ecological information, ornithologists in Brazil should increase their use of this tool in the future.

title: Effect of CCB Treatment and Alternative Adhesive Content on Physical and Mechanical Performance of Particleboards

description: Abstract The present study aimed to characterize medium density particleboard manufactured with CCB treated particles of Pinus sp. wood specie and alternative mixed vegetal oil-base bicomponent polyurethane resin. For this, three different resin concentrations (10 %, 12 % and 15 %) were used in combination with the presence or absence of the CCB preservative, resulting in six distinct treatments. The particleboards were produced according the Brazilian Standard - NBR and evaluated according European standards - EN. The results met the requirements of NBR and EN. The technical feasibility of making panels with those materials used were proved and the quality of the product according to its performance were verified, indicating the possibility to use alternative bicomponent polyurethane resin from mix vegetal oil. Statistical analysis demonstrated that adhesive and preservative factors and the interaction between them were significant on physical and mechanical properties.

title: Collapse tactics in performing arts: on the urgency of surviving and standing up

description: ABSTRACT This article evokes The Tower tarot card as an allegory to discuss collapse tactics within a specific performing arts project: the research staging process of the play The Vagabond, a One-Woman Music-Hall Show, developed during the Covid-19 global pandemic and produced by the Xama Teatro group (Maranhão state, Brazil). It reveals possible alternatives for a combined writing process of both script and staging, based on experiences of vulnerability and drawing on collapse as a tactic to provoke a process that constantly feeds back into itself. The procedures that stand out in the process are: improvising in an atelier environment; choosing references and mapping thematic fields; exploring problems; and experimenting with performative programs as a means to insist on surviving the Covid 19 global pandemic.

title: Epidemiological Aspects and High Magnitude of Human Visceral Leishmaniasis in Ceará, Northeast of Brazil, 2007-2021

description: ABSTRACT Background: Human visceral leishmaniasis HVL is endemic to 75 countries. The state of Ceará, the Northeast region of Brazil, is of great sanitary importance for the transmission of HVL, and it stands out as an area of interest for epidemiological aspects and control strategies. This study aimed to characterize HVL in relation to epidemiological aspects, composite incidence, and mortality rates in the state of Ceará, Brazil, from 2007 to 2021. Methods: This ecological study used temporal and spatial cuts of HVL data from the notifiable diseases information system. Epidemiological indicators such as incidence, mortality, and composite indices of incidence and mortality were calculated according to the Ministry of Health standardization. Results: There were 6,775 confirmed cases, with high incidence coefficients in 2009 6.96 cases/100,000 inhabitants and 2011 9.83 cases/100,000 inhabitants, and the highest mortality rate in 2011 6.96 deaths/100,000 inhabitants. The composite index of incidence and mortality identified municipalities in the Northern, Northwestern, and Southern regions of Ceará as having the highest risk of HVL. Conclusions: HVL remained endemic throughout the study period, with epidemiological indicators and risk of transmission expressing high magnitude, mainly in the Northeast, Northwest, and South regions of Ceará.

title: Angiosperm Diversity in the Semiarid Region of Ceará State, Brazil, with Emphasis on Caatinga Species

description: Abstract We examined the taxonomic diversity of native angiosperms in the semiarid region of Ceará State, Brazil, emphasizing species occurring in Steppic Savanna. The diversity of native angiosperms comprises 120 families, 604 genera, and 1,443 species. Fabaceae was the most taxonomically diverse family, while Croton (Euphorbiaceae) was the most species rich genus (33 sp.). Steppic Savanna species account for 58% of all angiosperms recorded in Ceará State, and 41% of all species listed for that phytophysiognomy in Brazil. An update of the species richness within the Steppic Savanna of Ceará State phytogeographical area is provided, also indicating distribution data for other phytophysiognomies in Ceará.

title: Study on the serum level of CoQ10B in patients with Moyamoya disease and its mechanism of affecting disease progression

description: ABSTRACT Background: At present, the etiology and pathogenesis of Moyamoya disease (MMD) are not completely clear. Patients are usually diagnosed after cerebrovascular events. Therefore, it is of great clinical significance to explore the predictive factors of MMD. Objective: This study aimed to investigate the serum level of CoQ10B, the amount of endothelial progenitor cells (EPCs), and mitochondrial function of EPCs in MMD patients. Methods: Forty-one MMD patients and 20 healthy controls were recruited in this study. Patients with MMD were divided into two groups: Ischemic type (n=23) and hemorrhagic type (n=18). Blood samples were collected from the antecubital vein and analyzed by CoQ10B ELISA and flow cytometry. Measures of mitochondrial function of EPCs include oxygen consumption rate (OCR), mitochondrial membrane potential, Ca2+ concentration, adenosine triphosphatases activity and ROS level. Results: The serum CoQ10B level in MMD patients was significantly lower than that in healthy controls (p&lt;0.001). The relative number of EPCs in MMD patients was significantly higher than that in healthy controls (p&lt;0.001). Moreover, the OCR, mitochondrial membrane potential and ATPase activity were decreased and the Ca2+ and reactive oxygen species levels were increased in MMD patients (p&lt;0.001). Conclusions: Our results showed obviously decreased serum CoQ10B level and increased EPCs number in patients with MMD compared with healthy patients, and the mitochondria function of EPCs in MMD patients was abnormal.

title: EXEMPLIFYING THE USE OF MACRO ELEMENTAL MAPPING BY XRF (MA-XRF) SCANNING IN FORENSIC INVESTIGATION OF ARTWORKS

description: EXEMPLIFYING THE USE OF MACRO ELEMENTAL MAPPING BY XRF (MA-XRF) SCANNING IN FORENSIC INVESTIGATION OF ARTWORKS. This work exemplifies the potential of employing macro elemental mapping by XRF (MA XRF) scanning in the forensic investigation of artworks. The results of the investigation of two artworks of different styles and periods are presented and discussed. The images provided by MA-XRF scanning have information about the elemental distribution, which is related to pigments used in the artwork. These images bring different information such as: if there are underlying paintings; if a given pigment was used for the purpose of restoration or in the creation. Therefore, through the images, it is possible to obtain information, which refers to the process of creating the artwork and the history of conservation and restoration. Through the results, it was possible to verify that the two artworks are probably false because they present anachronistic pigments with the supposed period of creation. The analyzes were performed using a portable MA-XRF scanning system, and in addition to presenting the utility of the instrument in these investigations, the work also presents possibilities to explore the MA-XRF data through multivariate statistical analysis and image correlation.

title: ENZYMATIC, CHEMOENZYMATIC AND PHOTOENZYMATIC CASCADE REACTIONS: PERSPECTIVES FOR A MORE SUSTAINABLE ORGANIC SYNTHESIS

description: Chemicals are rarely the result of a single transformation but rather the consequence of several individual reaction steps. Classically, these individual steps are carried out in sequence, including isolation and purification of the intermediate products. However, the reasons for choosing to carry out cascade reactions can be multiple, such as (i) the chance to prepare unstable and/or toxic intermediates, which are consumed directly in a subsequent step, (ii) the option to shift the equilibrium of a reaction by removing the co (product), or (iii) simply bypass the tedious work of isolating and purifying intermediates, saving reagents, solvents, time and money, and still generating less waste. Therefore, it is not surprising that so-called cascade reactions are gaining considerable interest in academic and industrial research. The purpose of this review is to show recent, promising research and new trends, the potential and current limitations of cascade reactions in organic synthesis that involves at least one enzymatic step in the cascade. This review will address cascades involving multi enzymatic, chemoenzymatic, and photoenzymatic cascades, where all steps are performed in one reaction vessel simultaneously or sequentially and the cascades in the regime of continuous flow.

title: The power of the SUS in the fight against Covid-19: allocation of resources and actions in Brazilian municipalities

description: Abstract This article aimed to analyze how municipal governments responded to the health crisis and what measures they developed in terms of diagnosing Covid-19 and allocating resources from Brazil’s federal sources. To this end, information from a survey with 4,061 mayors coordinated by the National Confederation of Municipalities was systematized and compared with other official databases. We concluded that, despite the lack of coordination instruments developed at the federal level, the allocation of resources and the development of policies by the municipalities were guided by the concentration of regional reference services in large and medium-sized municipalities.
