title: IT PROFESSIONALS IN NORTHEASTERN BRAZIL DURING A PROTRACTED CRISIS

description: This paper analyzes the new Information Technology (IT) segment in the Brazilian Northeast from the changes and trends brought about by the 2015 economic crisis, subsequently aggravated by the Covid-19 pandemic. It focuses particularly on labor status indicators among IT professionals in the region. To do so, it examines empirical studies previously carried out and secondary data, prioritizing the Annual Service Survey (PAS) and the Continuous National Household Sample Survey (PNADC), both from the Brazilian Institute of Geography and Statistics (IBGE), with greater emphasis on the Annual Social Information Report (Rais). Results showed that, both at the national and regional levels, the crisis negatively impacted this segment, despite its stock of formal jobs having continued its growth trajectory.

title: The macroscopic and microscopic description of ruminal lesions in feedlot bovine

description: Abstract Administration of diets rich in highly fermentable carbohydrates and low fiber content can cause an imbalance between the microorganisms in the rumen with consequent ruminal acidosis. This problem can cause lesions in the rumen wall, often progressing to rumenitis. The purpose of the present was to characterize macroscopic and microscopic ruminal lesions observed in confined feedlot cattle with claw lesions or liver abscess. A total of 1060 bovines were evaluated via postmortem examination. Claw lesions were identified in 88, liver abscess in 10, and macroscopic rumen lesions in 230 bovines; furthermore, 178 rumens were characterized with hyperkeratosis, 41 with hyperemia, 9 with ulcer, and 2 with neoplasia. The 98 bovines with claw lesions and liver abscess were selected for histopathological examination. Of these, macroscopic lesions were noted in 23 and microscopic lesions in 23 animals. Of the 23 animals that presented macroscopic lesions, 10 showed the same changes observed under microscopy. Seven cases of hyperkeratosis were diagnosed in the macro and microscopic evaluation. Of the 5 cases of hyperemia verified on macroscopy, 2 cases were identified via microscopy, and 1 case of ulcer identified through macroscopy and microscopy. The microscopic evaluation of the rumens allowed the identification of lesions in animals with claw lesions that did not present macroscopic rumen alterations.

title: Muscle pain induced by static contraction is modulated by transient receptor potential vanilloid 1 and ankyrin 1 receptors

description: Abstract Molecular mechanisms involved in the development of muscle pain induced by static contraction are not completely elucidated. This study aimed to evaluate the involvement of the transient receptor potential vanilloid 1 (TRPV1) and the transient receptor potential ankyrin 1 (TRPA1) receptors expressed in peripheral and central terminals of primary afferents projected to gastrocnemius muscle and spinal cord in muscle pain induced by static contraction. An electrical stimulator provided the contraction of rat gastrocnemius muscle and mechanical muscle hyperalgesia was quantified through the pressure analgesimeter Randall-Selitto. AMG9810 and HC030031 were used. When administered in ipsilateral, but not contralateral gastrocnemius muscle, drugs prevented mechanical muscle hyperalgesia induced by static contraction. Similar results were obtained by intrathecal administrations. We propose that, in an inflammatory muscle pain, peripheral and central TRPV1 and TRPA1 work together to sensitize nociceptive afferent fibers, and that TRPV1 and TRPA1 receptors are potential target to control inflammatory muscle pain.

title: ART restorations for occluso-proximal cavities in primary molars: a two-year survival and cost analysis of an RCT comparing two GIC brands

description: Abstract There are many glass ionomer cements available on the Brazilian market for Atraumatic Restorative Treatment (ART), however, there is still a gap in the literature regarding their cost-effectiveness. Objectives To evaluate the influence of restorative materials (Ketac Molar, 3M ESPE; and Vitro Molar, Nova DFL) in the two-year survival rate and cost-effectiveness of occluso-proximal ART restorations in primary molars. Methodology A total of 117 children (aged four to eight years) with at least one occluso-proximal carious lesion in primary molars were selected and randomly divided in treatment groups (KM or VM) in this parallel randomized controlled trial. Treatments followed ART premises and were conducted in public schools by trained operators in Barueri, Brazil. A trained, calibrated, and blinded examiner performed the evaluations after two, six, 12, and 24 months (k=0.92). Kaplan-Meier survival analysis was used to estimate restoration survival and Cox regression was used to test the association with clinical factors (α=5%). For cost analysis, material and professional costs were considered. Monte Carlo analysis was used to generate a cost-effectiveness plane and bootstrapping was used to compare material costs over the years. Results The overall survival rate was 36.9% after two years (48.6% for KM and 25.4% for VM). Restorations with VM failed more than those with KM (HR=1.70; 95% CI=1.06–2.73; p=0.027). VM presented lower initial cost, but no difference was observed between groups considering the two-year incremental cost. Conclusion After a two-year evaluation, KM proved to be a better option than VM for occluso-proximal ART restorations in primary molars. ClinicalTrials.gov: NCT02267720

title: Nutrient dynamic in cocoa leaves under different nitrogen sources: a reference tool for foliar analysis

description: Abstract Cocoa is a crop in increasing demand and cultivated worldwide. However, basic information concerning the movement of nutrients in leaves over time is still unknown, and methods to find an optimal time to collect a sample are still ambigu-ous. The present work focused on describing the movement of foliar nutrients (N, P, K, Ca and Mg) in productive 5-year-old cocoa clone CCN51 plants at the same dose of 114.8 kg ha-1 under different sources of nitrogen fertilization (Urea, calcium ni-trate, ammonium sulfate and a control without application). Samples were taken from the time the leaf reached 70% of its total expansion until 10 months of age. The results indicated that the contents of N, Ca and Mg increased as the leaf grew, remained stable between 116 and 158 days of shoot emergence (DSE) and then decreased at the beginning of the leaf senescence period. While the K and P con-tents decrease from the beginning of the trial until 158 DSE where they are stable until the final stage of leaf life. Around 110 to 120 DSE, the leaves of cocoa CCN51 show a more stable nutritional content, a period in which samples can be collected for leaf analysis.

title: Phytochemical profile, evaluation of antimicrobial and antioxidant activity in vitro of the hydroalcoholic extract of two species of the genus Cyperus (Cyperaceae)

description: Abstract Several factors contribute to the resistance of some pathogenic microorganisms and this fact requires the search for new therapeutic alternatives. The genus Cyperus (family Cyperaceae) groups species that present chemical compounds of pharmacological interest, mainly with antimicrobial action. Thus, the present work was carried out to investigate the antimicrobial activities, antioxidants and the phytochemical profile of Cyperus articulatus L. and Cyperus iria L. Hydroalcoholic extracts (1:1, v:v) of the aerial and underground parts of these species were used to analyze the total phenol content and to evaluate the in vitro antioxidant activity against the DPPH (2,2-diphenyl-1-picrylhydrazyl). The ethyl acetate and chloroform phases resulting from liquid-liquid partitioning of C. articulatus and C. iria extracts were evaluated in antimicrobial assays and subject to high performance liquid chromatography (HPLC-DAD) analysis. The chromatograms obtained by HPLC-DAD allowed us to identify four compounds: chlorogenic acid, catechin, quercetin, and quercitrin. The hydroalcoholic extracts of C. articulatus and C. iria showed a weak antioxidant activity with IC50 of 395.57 and 321.33 μg/mL (aerial parts), and 1,114.01 and 436.82 μg/mL (underground parts), respectively. Regarding antimicrobial activity, the chloroform phase of C. iria showed the best result at the concentration of only 31.2 µg/mL against the pathogens Candida albicans and Staphylococcus aureus. The ethyl acetate phases of the aerial parts of C. articulatus and C. iria did not show antimicrobial activity.

title: Optimization of HPLC method using central composite design for estimation of Torsemide and Eplerenone in tablet dosage form

description: Abstract A simple, precise, accurate and robust high performance liquid chromatographic method has been developed for simultaneous estimation of Torsemide and Eplerenone in tablet dosage form. Design of experiment was applied for multivariate optimization of the experimental conditions of RP-HPLC method. A Central composite design was used to study the response surface methodology and to analyse in detail the effects of these independent factors on responses. Total eleven experiments along with 3 center points were performed. Two factors were selected to design the matrix, one factor is variation in ratio of Acetonitrile and the second factor is flow rate (mL/min). Optimization in chromatographic conditions was achieved by applying Central composite design. The optimized and predicted data from contour diagram comprised mobile phase (acetonitrile, water and methanol in the ratio of 50: 30: 20 v/v/v respectively), at a flow rate of 1.0 ml/min and at ambient column temperature. Using these optimum conditions baseline separation of both drugs with good resolution and run time of less than 5 minutes were achieved. The optimized assay conditions were validated as per the ICH guidelines (2005). Hence, the results showed that the Quality by design approach could successfully optimize RP-HPLC method for simultaneous estimation of Torsemide and Eplerenone.

title: Dris norms for ‘Keitt’ mango in the Brazilian Semiarid Region:Diagnosis and validation

description: Abstract Nutritional standards based on long-term data improve the nutritional diagnosis of the crop, as they make norms more precise and establish more refined criteria. This study aimed to evaluate the nutritional status of the mango crop using the DRIS methodology to identify nutritional limitations and validate norms. A da-tabase of 202 commercial plots was used, whose leaves were collected in the floral induction period between 2011 and 2018 in the Brazilian semiarid region. The productivity of 'Keitt' mango under the Brazilian semiarid conditions was not related to NBI-DRIS. Nutrient concentration presents positive and significant relationship with the respective DRIS indices, enabling the determination of the balance point, establishing a nutritional standard and enabling the use of foliar diagnosis for the variety. The order of nutrients with the highest frequency of limitations due to lack, in decreasing order, was: Zn &gt; Al &gt; Na &gt; Cu &gt; S &gt; B &gt; Mn &gt; P = K &gt; Fe &gt; Ca &gt; N &gt; Mg, and limitation due to excess, in decreasing order was: Fe &gt; Na &gt; Mg &gt; Al &gt; Cu &gt; B = N &gt; S &gt; Ca &gt; P = K &gt; Zn &gt; Mn.
