Sharing Economy: The new economic institution
Authors: Acosta Libardo , Tello-Castrillón Carlos , Londoño-Cardozo José , Pasiminio Luisa Fernanda Rengifo
Published: April 2022

Abstract Sharing Economy is a new economic institution. This conclusion was reached from a thorough analysis of institutional theory and Schumpeter's proposal on consumption and technological revolutions. This is not a minor issue given its current importance and users’ trend, due to its institutionalization, towards the use of digital platforms for obtaining products and services. These platforms, called peer to peer or p2p, reduce uncertainty and build trust between the parties, while providing decision elements and analysis information. The platforms one of the key elements of this institution. The text deals with the main authors on collaborative consumption, their institutional status and their existence as a mechanism that allows addressing the social optimum, the super decisive agent of Harsanyi and the forms of consumption.

Authors: Simões Ana Clara Ramos , Antigo Mariangela Furlan
Published: April 2022

Resumo Este artigo tem como objetivo medir o desenvolvimento do estado de Minas Gerais sob a abordagem das capacitações. Para tal, foi elaborado e calculado um Índice de Ausência de Privação sob duas óticas para as mesorregiões e municípios do estado: municipal e de esforço orçamentário; e domiciliar. Os resultados de ambos os índices indicaram um forte antagonismo, com maior vulnerabilidade do norte e maior desenvolvimento do sul do estado, o qual é intensificado quando as privações são observadas a partir dos índices de bem-estar domiciliares. Ademais, foi possível observar maior desigualdade intrarregional na perspectiva municipal e maior desigualdade inter-regional na perspectiva domiciliar.
The political economy of the Workers’ Party governments in Brazil (2003-2014) - institutions, ideas and the main determinants of economic policy.
Authors: Guimarães Alexandre Queiroz
Published: April 2022

Abstract The article intends to understand key features of the economic policy trajectory followed by the Workers’ Party governments in Brazil. The period was characterized by advances in social conditions, but the governments failed to advance key social reforms, reduce high interest rates or pursue a coherent industrial policy. The policies adopted led to a deep economic crisis, a key component of the subsequent political impasse. The article adopts a historical-institutionalist approach, establishing a dialogue with theories that deal with the role of international constraints, the institutionalization of the party system, economic ideas and the influence of interest groups. The main contribution is to provide an interpretation which, by integrating economic, political and institutional factors, significantly adds to the understanding of key economic policy decisions.

Abstract This study was conducted to assess the in vitro response of human periodontal ligament stem cells (hPDLSCs) to bacterial lipopolysaccharide (LPS) activation and application of three calcium silicate-based materials (CSBM): Bio-C Sealer, MTA Fillapex and Cimmo HP. Characterization of the CSBM was performed by FTIR (n = 3). Extracts of Bio-C Sealer, MTA Fillapex and Cimmo HP were prepared and diluted (1:1, 1:4 and 1:16). Culture of hPDLSCs was established and treated or not with LPS from Escherichia coli (1 µg/mL) for 7 days. MTT assay was used to assess cell viability at 24, 48 and 72 h (n = 9). Alkaline phosphatase (ALP) activity was indirectly assayed at day 7 (n = 5). TNF-α and Il -1 0 cytokines were quantified by ELISA at 24h-cell supernatants (n = 6). Data were analyzed by ANOVA and Tukey’s test (α = 0.05). The cell viability of the LPS-activated hPDLSCs were higher than untreated control (p < 0.05). The application of CSBM affected the cell viability of untreated and LPS-activated cells (p < 0.05). ALP activity was higher for Bio-C Sealer and Cimmo HP in untreated and LPS-activated cells, respectively (p < 0.05). Application of CSBM normalized the TNF-α secretion in the LPS-activated cells (p < 0.05). Only MTA Fillapex in untreated hPDLSCs presented higher values of Il -1 0 (p < 0.05). Taken collectively, the results suggests that the simulation of the inflammatory process by LPS affect the in vitro response the hPDLSCs to the application of the CSBM.

Abstract This paper aimed to assess the influence of adhesive restoration interface on the diffusion of hydrogen peroxide (H2O2), indirect toxicity, and pro-inflammatory mediators expression by odontoblast-like cells, after in-office tooth whitening. Dental cavities prepared in bovine enamel/dentin discs were adhesively restored and subjected or not to hydrolytic degradation (HD). A whitening gel with 35% H2O2 (WG) was applied for 45 min onto restored and non-restored specimens adapted to artificial pulp chambers giving rise to the groups: SD- intact discs (control); SD/HP- whitened intact discs; RT/HP- restored and whitened discs; and RT/HD/HP- restored and whitened discs subjected to HD. The extracts (culture medium + WG components diffused through enamel/dentin/restoration interface) were collected and applied to odontoblast-like MDPC-23 cells. The study evaluated the amount of H2O2 in the extracts, as well as the cell viability (CV), cell morphology (CM), and gene expression of inflammatory mediators (TNF-α and COX-2) by the pulp cells exposed to the extracts (ANOVA and Tukey tests; 5% significance). All whitened groups presented lower CV than SD (control; p<0.05). The highest CV reduction and gene expression of TNF-α and COX-2 was observed in the RT/HD/HP group in comparison with SD/HP and RT/HP (control; p<0.05). CM alterations occurred in all whitened groups. The intensity of these cell side effects was directly related with the amount of H2O2 in the extracts. We concluded that adhesive restoration of dental cavity increases the H2O2 diffusion after in-office whitening, enhancing the indirect toxicity of this therapy and trigger pro-inflammatory overexpression by MDPC-23 cells.

Abstract To assess the impact of oral conditions on oral health-related quality of life (OHRQoL) in infants in ten Latin America countries (LAC). A cross-sectional study was conducted with 930 pairs of 1-to-3-year-old children/parents from 10 LAC, as a complementary study of the Research Observatory for Dental Caries of the Latin American Region. The scale ECOHIS, previously tested and valid in ten countries, was applied to parents/caregivers of children to measure OHRQoL. Statistical analysis included descriptive data analysis and one-way analysis of variance (ANOVA-One-Way) were performed to compare age groups with OHRQoL. Bootstrapping procedures (1000 re-samplings; 95%CI Bca) were performed. The mean scores of the ‘Child Impact’ section in the LAC was 4.0(±8.3), in the ‘Family Impact’ section was 2.0(±4.0), and in overall ECOHIS score was 6.0(±12.0). In the ‘Child Impact’ section, Argentina 10.0(+2.4) and Venezuela 17.8(±17.5) demonstrated mean scores higher than the LAC total data. In the ‘Family Impact’ section, the countries with higher mean scores were Argentina 4.9(±2.0), Ecuador 2.1(±3.1) and Venezuela 7.9(±7.8). In the overall ECOHIS score, Argentina 15.1 (±4.1) and Venezuela 25.7(±25.2) has higher mean scores than the values of LAC. There is an association between children's age and parents' report of impact on the OHRQoL (p<0.001). Three-year-olds had a higher mean when compared to one- and two-year-olds, both in the Impact on the Child and Impact on the Family (p<0.001) sections, as well as in the overall ECOHIS (p<0.001). In conclusion, there are differences in OHRQoL among Latin American countries, impacting older children more significantly.
Comportamento e seleção pelas consequências: a análise do comportamento no Brasil entre o dogma e a ciência
Authors: Benvenuti Marcelo Frota , Baia Fabio Henrique
Published: April 2022

Resumo Considerando-se as recentes discussões sobre a definição de comportamento e do modelo de seleção por consequências conduzidas por pesquisadores brasileiros, discutimos a necessidade de maior participação das contribuições da análise experimental do comportamento no debate de conceitos da área e mais interação da área com outros sistemas em Psicologia. Criticamos o isolamento em relação à produção de conhecimento de outras áreas e a adoção de figuras de autoridade a partir da qual se possa fazer a avaliação das novidades da área. Para tanto, a análise do contexto no qual Skinner propôs seu modelo de seleção por consequências precisa ser feita para clara compreensão das contribuições mais importantes dessa proposta. Mostramos que a discussão sobre a distinção operante-respondente e a pertinência da noção de metacontingências são exemplos de revisão conceitual feita com base em dados e articulação entre áreas de pesquisa com epistemologias e metodologias diferentes, mas possíveis de serem articuladas.

Authors: Prado Filho Roberto Romano do , Sanches Mariana Cardoso , Carregaro Adriano Bonfim
Published: April 2022

ABSTRACT: This study assessed the impact of different recumbency on sevoflurane-anaesthetised sheep. Seven female sheep were premedicated with 0.1 mg.kg-1 butorfanol and subsequently administered a combination of 3 mg.kg-1 ketamine and 0.5 mg.kg-1 midazolam. Animals were maintained on sevoflurane anaesthesia with pressure-controlled ventilation (12 cm H2O peak inspiratory pressure) and ƒ of 10 mpm. During the anaesthetic procedure, animals underwent one out of three different recumbency: dorsal, left lateral, or right lateral positions. Treatments lasted 120 min with a 48-h washout period in between the treatments. Arterial and central venous blood samples were withdrawn for blood gas and electrolytes analysis and pulmonary shunt fraction (Qs/Qt) CaO2, CcvO2, and CcO2 were calculated accordingly. Results showed that Qs/Qt greatly decreased from 0 to 120 min in all the groups (dorsal: 69.3% to 27.3%; left lateral: 59.1% to 25.0%; right lateral: 67.2% to 32.4%). CaO2, CcvO2 and CcO2 improved over time points, with no difference among treatments. PaO2 and PAO2 showed higher values for 60 and 120 min compared to the 0 min value in all groups, with no differences among treatments as well. PaCO2 and ETCO2 in the lateral groups were higher than those in the dorsal group at 120 min. Pressure-controlled ventilation improved gas exchanges in sheep, thereby reducing pulmonary shunt. Recumbency did not interfere with pulmonary shunt, nevertheless, special attention must be paid to lateral recumbency.

Published: April 2022

ABSTRACT: This study reports the optimization of the preparation of etoricoxib (ETX)-loaded low molecular weight of chitosan (LMWC) nanoparticles (ETX-LMWC-NPs) by ionic gelation method with sodium tripolyphosphate (TPP) as cross-linking agent. The independent variables (LMWC/TPP mass ratio, LMWC, and poloxamer 188 concentration) were formulated and optimized using response surface methodology (RSM) Box-Behnken design (BBD) with three levels for each factor. Size of particles, polydispersity index (PDI), and encapsulation efficiency was investigated as the dependent variable. ETX-LMWC-NPs were characterized by particle size analyzer, scanning electron microscope, UV-Vis spectrophotometry, and Fourier transforms infrared spectroscopy. The ETX-LMWC-NPs have an average particle size of 259.91 nm, a PDI of 0.041, and encapsulation efficiency of 51.25%. ETX-LMWC-NPs are spherical and have a spectrum at wavenumber 1656 cm-1 and 718 cm-1, respectively, indicating the presence of C=N and C-Cl originating from the ETX compound. The ETX release profile at pH 1.2 and 6.8 mediums approach the Korsmeyer-Peppas model. ETX released pH 1.2 did not differ significantly from free ETX with a maximum 10-12% release. ETX release at pH 6.8 had a maximum release of 21% and showed a 19% increase in dissolution rate than free ETX. The ETX-LMWC-CSNPs prepared by optimum formula (2.65 % LMWC, 5.5 LMWC/TPP mass ratio, and 1 mg/mL) showed stable monodispersity nanoparticles and easily soluble in water.

Abstract Improving plant germination is essential to guarantee better quality seedlings. Thus, this research aimed to evaluate whether the seed priming with light quality (LIQ) and the aqueous extract of Cyperus rotundus (AEC) tuber could modulate the germination and initial growth of Moringa oleifera L. seedlings. The experimental design was a completely randomized in the 4x4 factorial scheme, composed of four LIQ conditions (white, blue, red, and distant red light) and four AEC concentrations (0, 25, 50 and 100%). Seed priming with red light reduced the average emergence time, while blue, red, and extreme red lights associated with 50% of aqueous extract of C. rotundus increased shoot initial length and photosynthetic pigment accumulation. Seed priming with blue light resulted in seedlings with a shorter final shoot length. However, application of 100% of aqueous extract of C. rotundus reversed this. The white light in combination with concentrations of 50 and 100% of AEC promoted a higher relative shoot growth rate of seedlings. The research revealed that seed priming with light quality and aqueous extracts of C. rotundus tubers modulates the germination and initial growth of M. oleifera seedlings. More work needs to be done to determine the responsible compounds in AEC that is responsible for priming growth as phytohormones.

ABSTRACT: Mineral deficiencies are important causes of productive losses in ruminant farming, especially in semiarid regions. This study aimed to determine Na, K, and Cl serum concentrations, plus the salivary concentrations of Na and K in sheep raised in a semiarid region of Northeastern Brazil, and to report the epidemiology, clinical and the pathological aspects of an outbreak of hyponatremia in sheep. For this, serum and salivary samples of 55 sheep were collected in 6 different farms in the region. Na, K, and Cl concentrations were determined by colorimetric test, using commercial kits in a semi-automatic biochemical analyzer. The mean serum concentrations ranged from 131.5±13.1mEq/L to 172.4±9.3mEq/L for Na, 6.28±1.3mEq/L to 13.9±1.4mEq/L for K, and 91.6±54.8mEq/L to 113.6±1.5mEq/L for Cl. The mean salivary concentrations ranged from 119.4±9.5mEq/L to 161.8±15.2mEq/L for Na, 10.1±3.1mEq/L to 22.3±2.3mEq/L for K, and the ratio Na:K ranged from 6.0±1.3mEq/L to 11.8±4.1mEq/L. These results revealed that most sheep raised in the farms in this region are marginally depleted in sodium. In one farm, sheep had severe clinical signs of Na deficiency consisting of haggard appearance, craving for salt, polydipsia, polyuria, dry cough, inappetence, pica, weakness, difficulty to rise and move, severe emaciation, and dehydration. On autopsy, the ruminal content was generally impacted, giving to the content an aspect of clay balls. Four sheep presented hypertrophy of the adrenal glands. Histopathologically, the width of the zona glomerulosa was expanded, there was loss of the architecture and loss of adrenocortical cell cords. The epithelial cells in the zona glomerulosa and fasciculata were pyramidal, and contained hypereosinophilic cytoplasm and hyperchromatic nuclei. These data demonstrate the occurrence of Na deficiency in different degrees in sheep farms in the State of Pernambuco and highlight the importance of providing NaCl to avoid outbreaks of hyponatremia.

ABSTRACT: The aim of this study was to describe the epidemiological, clinical, and pathological findings of two outbreaks of gastrointestinal nematode infections in beef cattle kept under an inadequate sanitary protocol. An outbreak of trichostrongylosis occurred in Amambai, Mato Grosso do Sul (MS), from May to July 2016. The herd consisted of 3,000 Nellore cows, and of these, fifteen died after showing emaciation and diarrhea and remaining in recumbency. At necropsy, the abomasum showed edema in the folds, white, raised areas, multifocal to coalescent, and small ulcers. Histopathology showed larvae compatible with trichostrongylid nematodes were present inside the abomasum glands. Trichostrongylus axei was identify in the abomasum. The hemonchosis outbreak began in October 2018, in a breeding and finishing property in Santa Rita do Pardo, MS. Of 4,000 cattle aged 8 to 18 months, 673 became ill and 117 died. Clinical signs were emaciation, weakness, dehydration, submandibular edema, and soft stools. At necropsy, large numbers of nematodes were found in the abomasum; they were morphologically classified as Haemonchus placei. Both outbreaks were caused by failures in the parasite control protocol. However, in Outbreak I, frost and immune stress caused by lack of food may have contributed to the deaths. In Outbreak I, the main failure in the devermination protocol was the use of anthelmintics without carrying out an efficacy test. In Outbreak II, there was no parasite control protocol in the rearing and finishing property, and in the breeding property, there was resistance to the anthelmintic used (ivermectin). The two outbreaks highlight the importance of gastrointestinal nematode control protocols in cattle and demonstrate that infections by T. axei and H. placei can be lethal for this species.
Viability of Universal Life insurance in Brazil from the supply and demand perspectives
Authors: Ikeda Mariana Mayumi Shiroma , Carvalho João Vinícius de França
Published: April 2022

ABSTRACT The aim of this article was to evaluate the viability of Universal Life insurance (UL) in Brazil from two perspectives: from the individual viewpoint of policyholders, considering different client profiles and investment scenarios; and from the company viewpoint, verifying whether insurers see sales advantages in UL. Thus, despite the lack of definition of the regulations on these contracts by the Superintendence of Private Insurance (Susep), this article’s contribution lies in evaluating UL - a typically American product - in Brazil, using an entirely actuarial methodology, for policyholders and insurers, according to local parameters. The relevance of the article lies in strengthening the support for individuals, companies, and authorities to evaluate the product and discuss its implementation, even identifying the most favorable profiles and scenarios for its development. Although the UL is an individual modality that is widespread in several countries and its design exploits well-defined attractions, the product has not been explored in the national literature. The methodology adoted in this study used fully actuarial modeling, the internal rate of return (IRR), and profit testing. The study reveals that the Brazilian market for UL is viable, especially due to the higher interest rates compared to countries where the product is already widespread. From a demand perspective, the results indicate that the policyholder would be in a more advantageous position acquiring UL than buying life insurance in the private market and investing the surplus in financial assets, due to the hybrid characteristic of the contract, which enables the use of financial returns as discount factors in the insurance portion and operational charges, reducing the opportunity costs linked to the product. With regard to companies, the profit testing results suggest there are stimuli for the supply of UL, provided the operation has a long-term bias. Altering the mortality pattern, policy type, and the company’s investment profile, all the results point in a similar direction.
Influence of budgetary slack and elements of the budgetary process on perceptions of justice,
Authors: Santos Vanderlei dos , Beuren Ilse Maria , Skrepitz Suzimara
Published: April 2022

ABSTRACT This study examined the relationships between elements of the budgetary process (budgetary participation, the use of budgetary goals for performance assessments, and the use of budgetary goals for variable remuneration purposes), budgetary slack, and perceptions of justice, on the assumption that budgetary slack is an antecedent of perceptions of justice and acts as an intervening variable between elements of the budgetary process and perceptions of justice. Studies addressing the relationship between justice and slack have not considered the positive aspects derived from budgetary slack such as necessary and emergency resources. Moreover, most of these studies have focused on procedural justice and on an element of the budgetary process (budgetary participation), to predict feelings of justice and the creation of slack. The results of the study suggest alternative conceptions for analyzing the relationship between perceptions of justice and budgetary slack, going beyond the economic lens for the latter. By resorting to social exchange theory (SET), a perspective is provided on how elements of the budgetary process affect managers’ perceptions of justice and how budgetary slack, as an economic and social exchange resource, shapes those effects. Although researchers have already pointed to budgetary slack as being beneficial for the organization, no studies were found that have analyzed it as a predictor of perceptions of justice. A survey was conducted with a sample of 114 company managers and the hypotheses were tested with the application of structural equation modeling. The results reveal that budgetary slack is an inherent element of the budgetary process, conceived as an economic and socioemotional resource, according to the principles of SET, and used by organizations with a view to greater perceptions of justice. Budgetary slack is essential for predicting managers’ feelings of distributive and procedural justice regarding the budgetary process.

Published: April 2022

Abstract Objective: To describe adolescents’ everyday activities and emotional consequences related to the COVID-19 pandemic. Method: Qualitative study grounded in Alfred Schütz’s social phenomenology, involving 22 students at two public schools in a municipality in the state of São Paulo, Brazil. Interviews were conducted, had their audio recorded, and were analyzed according to a thematic categorization. Results: Five categories emerged from the accounts: i) adolescents’ reaction before the COVID-19 pandemic; ii) emotional consequences; iii) concern about the family; iv) adolescents’ adaptation; and v) fragmentation of social support networks. Feelings such as uncertainty, fear, anguish, anxiety, and lack of motivation, depressive symptoms, and extreme suicidal ideation were reported. Conclusion: Paying attention to adolescents’ psychosocial needs is essential, especially in face of the possibility of post-traumatic stress as a result of the COVID-19 pandemic. Health professionals’ technical competence combined with sensibility, strengthening of social support networks, and engagement of different community sectors are fundamental for promoting adolescent mental health in the current transition and resignification period following the COVID-19 pandemic.

ABSTRACT Objective: to analyze, in the literature, the nurses' knowledge, attitudes and practices regarding Hepatitis B. Method: an integrative review, with search and selection conducted independently by peers, after electronic queries in the CINAHL, MEDLINE, SCOPUS, Web of Science, LILACS, BDENF and IBECS databases in January 2021. The sample consisted in 15 primary studies published with no time or language restrictions. Analysis and synthesis of the results were carried out in a descriptive manner. Results: limitations in knowledge, inconsistent attitudes and commonly neglected assistance-related practices were identified, related to prevention, immunization and biosafety measures, to risk management and to monitoring of symptoms and complications, which contributed to greater occupational exposure. Among the associated factors, low participation in permanent education activities, training level, working conditions, limitations in the availability of immunization tests (anti-HBs) and underreporting of health problems stood out. Conclusion: the knowledge, attitudes and practices developed by nurses in relation to Hepatitis B proved to be limited and inconsistent, which may result in greater occupational exposure, as well as exert a direct impact on vaccination coverage and occurrence of incidents.

ABSTRACT. The prevalence of Parkinson's disease (PD) tends to increase worldwide in the coming decades. Thus, the incidence of falls is likely to increase, with a relevant burden on the health care system. Objective: The objective of this study was to evaluate clinical factors and drug use associated with falls in PD patients. Methods: We conducted a cross-sectional study at the Movement Disorders outpatient clinic of a tertiary hospital in Northeast Brazil. We performed structured interviews to collect sociodemographic and clinical data. Functional capacity was assessed using the Schwab and England Activities of Daily Living Scale and the modified Hoehn and Yahr Staging Scale. We divided the study sample into non-fallers (no falls) and fallers (≥1 fall), and non-recurrent (≤1 fall) and recurrent fallers (>1 fall). Results: The study population comprised 327 PD patients (48% women), with a mean age of 70 years. The mean disease duration was 9.9±6.9 years. The most prevalent comorbidities were depression (47.2%), hypertension (44.0%), and type 2 diabetes mellitus (21.5%). The logistic regression analysis revealed that hallucinations, amantadine, and catechol-O-methyltransferase inhibitors (entacapone) were independently associated with falls in PD patients. Also, hallucinations, dyskinesia, and the use of amantadine were independently associated with recurrent falls. Conclusions: Health care providers play an essential role in fall prevention in PD patients, particularly by identifying older adults experiencing dyskinesia and visual hallucinations. Prospective studies should investigate the use of amantadine as a risk factor for falls in PD patients.

ABSTRACT. Non-pharmacological interventions, such as the use of music, have been shown to be important potential means of controlling adverse symptoms and signs resulting from chronic diseases already present in elderly patients with dementia. Objectives: The objective of this study was to analyze the effects of concert music on cognitive and physiological parameters, and behavioral and psychological symptoms in institutionalized elderly people with dementia. Methods: A descriptive-exploratory, quantitative, quasi-experimental study was conducted with 14 elderly people. They were allocated in intervention group (IG) (n=7) with eight sessions of music listening, once a week, for 2 months, and control group (CG) (n=7) with the same procedure but without listening to the music. All participants were assessed by Neuropsychiatric Inventory Questionnaire (NPI-Q) and Addenbrooke’s Cognitive Examination – Revised (ACE-R) before and after the intervention. Blood pressure (BP) data were obtained; heart rate (HR) and coherence were obtained through Cardioemotion during sessions. The data were analyzed using Fisher’s exact test and Student’s t-test. Results: There was a predominance of female participants, who were widowed and diagnosed with Alzheimer’s disease (AD) in both groups. A statistically significant reduction was found in the mean of apathy reduction (p=0.038) and the total mean of NPI-Q severity (p=0.033) (paired Student’s t-test) in IG. No significant differences were found in mean level of the pre- and post-analysis variables in CG. Conclusions: Concert music had a positive effect on the behavior of institutionalized elderly. Stimuli and possibilities of improving the current behavioral conditions are observed.

Published: April 2022

Abstract Introduction: methylisothiazolinone alone or associated with methylchloroisothiazolinone (Kathon CG) is a preservative related to occupational allergic contact dermatitis. Objectives: to evaluate the demographic and clinical profile of occupational cases of sensitization to isothiazolinones in the city of Rio de Janeiro and to describe the presence of these preservatives in national paints. Methods: cross-sectional study based on information from medical records of workers who underwent patch testing between 2013-2017. The prevalence of clinical, demographic and occupational characteristics was described and an unadjusted model was used to investigate the association between variables. We sought the presence and concentration of isothiazolinones in the chemical composition sheets of national paints. Results: among the 768 workers submitted to the tests, 68 had occupational dermatosis with a positive result for sensitization to methylisothiazolinone/Kathon CG. The most affected occupations were those related to domestic activities and cleaning. There was a greater likelihood of sensitization to isothiazolinones in women and in those with involvement of the hands and legs. Among the 61 paints evaluated, 26 had some isothiazolinone, with methylchloroisothiazolinone being the most common. Conclusions: sensitization to isothiazolinones can impact workers’ health and demands greater vigilance on cleaning materials and cosmetics, as well as discussing the composition regulation of the paints sold in Brazil.

ABSTRACT The calpain system is the central player for meat tenderization and the calpastatin activity plays an important role in beef tenderness of Bos taurus indicus cattle. This study investigated whether dietary vitamin D3 induced gene expression of μ-calpain (CAPN1), total calpastatin (CAST T), and their variants (CAST I and II). Animals received none or 2 × 106 IU of vitamin D3 for either 2 or 8 days before slaughter and were submitted to different conditions during feedlot: sun exposure or artificial shade. Steaks from Longissimus lumborum were fabricated, aged for 1, 7, and 21 days post-mortem, and later used for the analyses of shear force and the myofibrillar fragmentation index. Vitamin D3 did not influence mRNA abundance; however, it induced a greater CAST II transcript in animals supplemented 8 days before slaughter. There was a negative association between CAST II abundance and the shear force, which revealed an important modulation of the calpain system expression due to vitamin D supplementation. This result is an important tool for strategies to improve beef tenderness.
Distribution of agromineral resources in space and time – a global geological perspective
Authors: Straaten Peter van
Published: April 2022

Abstract Agromineral resources are minerals and rocks used to improve soil productivity and health. These resources can be applied: indirectly, by extracting and concentrating one or more minerals by industrial processes for the production of conventional, highly soluble fertilizers; and directly, without processing, except fine grinding, for direct soil application. Agromineral resources include sedimentary phosphates, limestones/dolostones, potash and glauconite-bearing rocks of sedimentary origin, basaltic rocks, phonolites, kamafugites, and glass-rich mafic rocks of igneous origin. Among metamorphic agromineral resources, marble and biotite schist stand out. However, agromineral resources are not equally distributed on Earth’s surface, occurring more in one area than in another, and have accumulated in various geotectonic settings related to plate tectonics, being formed in specific geological time periods in Earth’s history. Therefore, these resources occur in specific “agromineral provinces” and were formed during specific “agromineral epochs”. This paper provides a conceptual framework for agromineral resource distribution in time and space. Agrominerals have a high potential to be used as directly applied soil amendments and soil remineralizers for new and innovative farming strategies, provided the amendments are low or free of contaminants.

Published: April 2022

Abstract The objective of this work was to evaluate the experimental precision of ten statistics in the evaluation of characters related to the technological quality of common bean (Phaseolus vulgaris) lines. Seventeen experiments were carried out between 2010 and 2019, with 116 common bean genotypes of different types of grain. Technological quality was determined for the following characters: mass of 100 grains, grain lightness value (L*), absorption, and cooking time. A significant genotype effect was obtained in 100% of the experiments for L* value and mass of 100 grains, in 76.92% for absorption, and in 94.12% for cooking time. The L* value and mass of 100 grains were determined with a high experimental precision by all statistics. Absorption and cooking time showed a high experimental precision, when analyzed by the following statistics: F-test value for genotype (Fc), genetic variation coefficient (GVC), relative variation coefficient (RVC), heritability (h2), and selective accuracy (SA). The statistics Fc, GVC, RVC, h2, and SA provided a high experimental precision in the evaluation of the characters related to technological quality in common bean lines. Selective accuracy is the most appropriate statistics to select superior common bean lines for grain and cooking quality in breeding programs.
