A simple and low-cost environmental enrichment program improves the welfare of Calomys callosus, a species that adapts to animal facilities.

An environmental enrichment protocol is essential for testing experimental models because it upholds animal welfare, aligns with ethical principles in animal experimentation, and reduces the number of animals needed. Calomys callosus, a South American rodent from the Cricetidae family, is bred in rodent animal facilities for its ease of handling, longevity, prolificacy, and effectively mimicking diseases like Toxoplasmosis, Leishmaniasis, Chagas, and Schistosomiasis. There are no reports on environmental enrichments for this species or their impact on reproductive parameters. This study aimed to analyze the influence of the Environmental Enrichment Program (EEP) on the reproductive and zootechnical performance of C. callosus kept in the Rodents Animal Facilities Complex of Universidade Federal de Uberlândia (UFU). Two experimental groups were established: with environmental enrichment EE+ and without environmental enrichment EE-. The materials used in the experimental design were changed weekly and alternated between dietary, occupational, physical/cognitive, and non-enrichment items. After the inclusion of the EEP, an improvement in the reproductive indices of C. callosus was identified in the EE+ group. These improvements included increased female precocity, a decreased interbirth interval, and a higher number of pairs producing more offspring. The postpartum zootechnical indices were also better, such as the number of animals born alive, improved weaning rates, and a reduced average number of deaths from birth to weaning. After the inclusion of the EEP, the general health status of C. callosus improved, reducing cases of non-infectious lumbar alopecia. Therefore, EEP allows C. callosus to express natural reproductive behaviors and improves parental care.

Association of salivary alpha-2-macroglobulin with glycemia and glycated hemoglobin in type 2 diabetes mellitus: a systematic review and meta-analysis study.

Chronically elevated alpha-2-macroglobulin (A2MG) in the blood has been correlated with diabetes and the HbA1c profile; however, no systematic review has been conducted to evaluate the association of A2MG salivary levels and glycemia or HbA1c levels in diabetes mellitus type 2 (DM2) patients. To evaluate whether A2MG salivary levels are related to the glycemia or HbA1c levels in DM2 patients. Systematic review developed at Universidade Federal de Uberlândia (UFU), Brazil. Eight databases were used as research sources. The eligibility criteria included studies that reported data regarding mean salivary A2MG and the correlation between glycemia and/or HbA1c levels of DM2 subjects (uncontrolled and well-controlled) and non-diabetic subjects. The risk of bias of the studies selected was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools for use in JBI systematic reviews. Pooled correlation coefficients were estimated using the Hunter-Schmidt method. Study estimates were weighted according to their sample size, and heterogeneity was calculated using the chi-square statistic. Four studies on DM2 patients were included in this systematic review after careful analysis of 1482 studies. Three studies compared A2MG with HbA1c and glycemia. Overall, the correlation between A2MG and HbA1c was strong (r = 0.838). In contrast, the correlation between A2MG and glycemia was low (r = 0.354). The strong association between HbA1C and salivary A2MG suggests that this salivary protein has the potential to be a surrogate for HbA1C, if corroboratory further evidence is obtained through large-scale studies.

Selection of BC1F3 populations of Santa Cruz type dwarf tomato plant by computational intelligence techniques

ABSTRACT The aim of this study was to estimate genetic divergence and select BC1F3 populations of dwarf tomato plant within the Santa Cruz segment by computational intelligence techniques. The experiment was conducted in a greenhouse in the Vegetable Crop Experimental Station of the Universidade Federal de Uberlândia (UFU), Monte Carmelo, MG, Brazil. A randomized block experimental design was used with 17 treatments and four replications. The genetic material evaluated comprised thirteen dwarf tomato plant populations obtained by a backcross and two self-fertilizations, plus both parents (recurrent and donor), and two commercial check varieties. The traits evaluated were mean fruit weight (MFW), soluble solids content (SSC), fruit diameter (FD), fruit length (FL), fruit shape (FS), pulp thickness (PT), number of locules (NL), distance between internodes, and acylsugar, β-carotene, and lycopene content. The data were analyzed by means testing, and genetic divergence was measured using Mahalanobis generalized distance by the unweighted pair group method with arithmetic mean (UPGMA) and through computational intelligence using Kohonen self-organizing maps (SOM). Genetic dissimilarity in relation to the donor parent could be confirmed through both methodologies. However, the SOM was able to detect differences and organize the similarities among the populations in a more consistent manner, resulting in a larger number of groups. In addition, the computational intelligence techniques allow the weight of each variable in formation of the groups to be ascertained. Among the BC1F3 populations, UFU-SC#3 and UFU-SC#5 stood out for agronomic traits, and UFU-SC#10 and UFU-SC#11 stood out for quality parameters.

Esta exposição traz reflexões e criações realizadas com teatro de sombras, teatro de objetos e teatro lambe-lambe, além de dialogar com artistas mulheres que foram inspiração e grande influência nas experiências cênicas e espetáculo criado pela respectiva autora.

Productivity, acylsugar concentrations and resistance to the two-spotted spider mite in genotypes of salad tomatoes

ABSTRACT The objective of this study was to characterize genotypes of the salad-type tomato with a determinate growth habit and select genotypes resistant to the two-spotted spider mite for higher productivity and fruit quality. The experiment was conducted at the Horticultural Experimental Station (18°42’43.19” S and 47°29’55.8” W, 873 m altitude) of the Universidade Federal de Uberlândia (UFU), Monte Carmelo campus, from January to June 2018. The experimental design was in randomized blocks containing 16 treatments [12 populations of the F3RC2 generation and four controls: two commercial cultivars (Santa Clara and Rio Grande), the recurrent parent (UFU-057) and the wild species Solanum pennellii (LA-716)] with three repetitions. The accessions UFU-057F3RC210#3.6.1 and UFU-057F3RC213#2.1.2 have high potential for genetic improvement regarding resistance to the two-spotted spider mite. The genotypes UFU-13#4.4.1, UFU-7#4.7.1, UFU-7#4.3.2, UFU-13#2.5.2 and UFU-13#2.1.3 present higher acylsugar concentrations than S. pennellii, in addition to higher productivity and number of fruits per plant. It is suggested to explore combinations between those genotypes previously described with UFU-8#2.4.1 to obtain hybrids with high acylsugar concentrations, two-spotted spider mite resistance, high productivity and increased fruit mass.

Different roughage: concentrate ratios in extruded feed, and feeding behavior of growing lambs

Animal performance is directly related to the food quality and intake.Analyzing feeding behavior is an important tool to evaluate diet efficiency.This study aims to evaluate the intake of dry matter, feeding behavior andruminal movement amongst lambs fed with extruded feed in differentroughage (R) : concentrate (C) ratios. An experiment was carried out in theExperimental Farm Capim Branco, Universidade Federal de Uberlandia,from December 7, 2016 to March 22, 2017. It involved 30 3-month-oldcrossbred lambs (Santa Ines x Dorper) with a mean weight of 20.67 ± 4.57kg allocated in collective stalls equipped with feeder, water fountain, saltshaker, and wooden slatted floor. The experiment was conducted in arandomized complete design with 2 treatments and 15 replicates pertreatment. The treatments consisted of roughage and concentrate extrudedand mixed in the following ratio 30R:70C and 70R:30C. The dry matterintake (DMI), 24-hour feeding behavior and 5-minute ruminal movementwere evaluated. The findings pointed to reduced DMI in relation to bodyweight for 30R:70C at the end of the experiment. Reduced rumination time,total chewing and ruminal movement were found for both ratios. However,shorter rumination time and total chewing had been recorded for 30R:70Cat the beginning of the experiment. Extruded feed with 70R:30C increasedrumination and total chewing and, consequently, ruminal movement.

Este artigo, voltado para o processo de internacionalização da Universidade Federal de Uberlândia (UFU), investiga dois sítios eletrônicos dos seus programas de pós-graduação (PPG), ambos com versões em língua inglesa. A análise da tradução dos sítios de ambos os programas revela problemas de ordem linguística, cultural e tradutória, havendo a necessidade de revisão e tradução de diversos conteúdos, bem como de reconfiguração de alguns detalhes visuais. Na tentativa de promover reflexão sobre um dos aspectos da internacionalização do ensino superior no Brasil, qual seja a internacionalização dos seus sítios eletrônicos, são feitas algumas propostas de reformulações e considerações que ensejam uma reflexão sobre a internacionalização de sítios eletrônicos universitários e a sua interface com os Estudos da Tradução.

Tiller dynamics in Piatã palisade grass submitted to nitrogen fertilization

The objective of this study was to determine the residual effect of nitrogen fertilization applied at the time of the waters on the demography of tillers of Urochloa brizantha cv. Piata kept under cut simulating manning continues in the dry season. The experiment was installed in the farm Capim Branco da Universidade Federal de Uberlândia (UFU), located in the city of Uberlândia, Minas Gerais. It was established the Piata grass (Urochloa brizantha cv BRS Piata) in September 2011 in an area of 9 m 2 plot -1 . The experimental design was a completely randomized block design, with four replications, with treatments distributed in a 4 x 5 factorial scheme, in which the first factor doses of urea (0, 100, 200, 400 kg ha-1 of N), demarcated in four applications always performed after the demotion of experimental units and the second factor was the time of evaluation (May, June, July, August and September). Performed the evaluations of the tillering dynamics during five months, assessing rate of appearance, mortality and survival, as well as the stability index of the population and population density, analyzing data by the method of Student-Newman-Keuls (SNK). The use of N doses did not affect the tillering of Piata grass in the dry season, due to the implementation of this have occurred with low water availability in the soil. The development of the plant is linked to the amount of water present in the soil, reducing your energy expenditure, consequently decreasing your development and production.

A Adoção do SISU e a Evasão na Universidade Federal de Uberlândia

The main objective of this study was to determine the percentage of the behavior of dropout students in the years before (2006-2010) and after (2011-2014) the adoption of the Brazilian Unified Selection System (SISU) in the Universidade Federal de Uberlândia (UFU). This is a documentary research. The Data about evasion were obtained with the Dean of Graduate ( PROGRAD ) . In the first part of the verification of information it was held the organization of data on dropout students of the UFU in the period analyzed, and treated 15,088 occurrences. Then the data were classified and summarized and after the binomial statistical test was applied. In the results, the Applied Social Sciences, Humanities and Exact Sciences and Earth areas were those with the highest percentages of dropout students. By analyzing the average by areas, the Agricultural Sciences, Biological Sciences, Engineering, Exact Sciences and Earth and Health Sciences areas presents significant increase in the percentage of dropout students after the SISU. While the Humanities, Linguistics, Literature and Arts and Social Sciences areas showed significant reductions in the percentage of dropout students.

Temporomandibular disorder and anxiety, quality of sleep, and quality of life in nursing professionals

To evaluate the association between temporomandibular disorder (TMD) and anxiety, quality of sleep, and quality of life in nursing professionals at the Hospital de Clínicas de Uberlândia of the Universidade Federal de Uberlandia--HCU-UFU (Medical University Hospital of the Federal University of Uberlândia), four questionnaires were given to nursing professionals. The questionnaires were completed by 160 of these professionals. The Fonseca's questionnaire was used to evaluate the presence and severity of TMD, the IDATE was used to evaluate anxiety, the SAQ was used to evaluate quality of sleep, and the SF-36 was used to evaluate quality of life. Forty-one nurses (25.6%) reported having no TMD (Fonseca's questionnaire score ≤ 15), 66 (41.3%) had mild TMD (Fonseca's questionnaire score 20-40), 39 (24.4%) had moderate TMD (Fonseca's questionnaire score 45-65), and 14 (8.8%) had severe TMD (Fonseca's questionnaire score ≥ 70). According to Fonseca's questionnaire, the presence of TMD was associated with trait anxiety, but the TMD severity was associated with state anxiety classification (mild, moderate, severe). The SAQ score differed significantly from Fonseca classification. The Fonseca's questionnaire score correlated negatively with the score of each dimension of the SF-36 (r = -0.419 to -0.183). We conclude that TMD is common among nursing professionals; its presence was associated with trait anxiety, and its severity was associated with state anxiety. Hence, the presence of TMD may reduce quality of sleep and quality of life.

Evaluation of soybean lines and environmental stratification using the AMMI, GGE biplot, and factor analysis methods.

In the final phases of new soybean cultivar development, lines are cultivated in several locations across multiple seasons with the intention of identifying and selecting superior genotypes for quantitative traits. In this context, this study aimed to study the genotype-by-environment interaction for the trait grain yield (kg/ha), and to evaluate the adaptability and stability of early-cycle soybean genotypes using the additive main effects and multiplicative interaction (AMMI) analysis, genotype main effects and genotype x environment interaction (GGE) biplot, and factor analysis methods. Additionally, the efficiency of these methods was compared. The experiments were carried out in five cities in the State of Mato Grosso: Alto Taquari, Lucas do Rio Verde, Sinop, Querência, and Rondonópolis, in the 2011/2012 and 2012/2013 seasons. Twenty-seven early-cycle soybean genotypes were evaluated, consisting of 22 lines developed by Universidade Federal de Uberlândia (UFU) soybean breeding program, and five controls: UFUS Carajás, MSOY 6101, MSOY 7211, UFUS Guarani, and Riqueza. Significant and complex genotype-by-environment interactions were observed. The AMMI model presented greater efficiency by retaining most of the variation in the first two main components (61.46%), followed by the GGE biplot model (57.90%), and factor analysis (54.12%). Environmental clustering among the methodologies was similar, and was composed of one environmental group from one location but from different seasons. Genotype G5 presented an elevated grain yield, and high adaptability and stability as determined by the AMMI, factor analysis, and GGE biplot methodologies.

Noise Source Distribution of Coaxial Subsonic Jet-Short-Cowl Nozzle

The noise source distribution of a short-cowl coaxial jet operating at different velocity ratios is described in this work. This was motivated by an ongoing research about noise prediction of coaxial jets through Acoustic Analogy with purposes of industrial engine application. This research has been carried out between Universidade Federal de Uberlândia (UFU), Brazil and the Institute of Sound and Vibration Research (ISVR) at Southampton University, UK. The numerical approach employed is originally based on Lighthill Acoustic Analogy. This technique, although likely known, is associated with an improved energy transfer time-scale, used in the turbulence two-point correlation function, in order to enhance the source model. The source model is coupled with the aerodynamic calculation of flow through turbulence quantities evaluated by using a standard k-e turbulence modeling. The Computational Fluid Dynamics data have also been used to provide complementary information about the coaxial jet noise production mechanisms. Experimental data were used in order to corroborate the results from the current model. Good agreement has been found, showing that high and low frequency contributors to the radiated noise for low velocity ratio are aggregated in a region about seven to ten secondary diameters downstream, while at higher velocity ratios sources are continuously spread from about one up to ten secondary diameters from the jet exit.

COMPETÊNCIAS NA PÓS-GRADUAÇÃO: O OLHAR DOS EGRESSOS

<p>A presente pesquisa objetiva analisar o que significa competência para os egressos de um curso de mestrado em administração que atuam como docentes, com base na experiência vivenciada no programa de pós-graduação em Administração. Buscou-se, ainda, identificar as atividades do programa subjacentes às competências constituídas. Adotou-se o estudo de caso como estratégia de pesquisa, em que, como fontes de dados, tomaram-se documentos do programa e os egressos que atuam como docentes. Os dados foram coletados por meio de levantamento documental, entrevistas eletrônicas, grupos focais e entrevistas em profundidade; e as análises envolveram o uso da análise documental e da análise temática de conteúdo. Os resultados apontam para a formação de competências pelos egressos em sete dimensões: metacompetências e transcompetências, intelectuais, técnico-funcionais, comportamentais, éticas, políticas e identitárias. Nesse sentido, foi possível observar a exequibilidade dos objetivos de formação do ppga, bem como daqueles asseverados pelas diretrizes do sistema brasileiro de pós-graduação. Contudo, verificou-se que o ppga tem contribuído para a formação de um egresso que relata mais sobre o domínio das habilidades e dos conhecimentos técnicos e científicos, e menos sobre o domínio das capacidades relacionais, éticas, políticas e identitárias, nas quais pesa o foco sobre a formação para a pesquisa, em detrimento da formação para o processo de ensino.<br /> </p>

Cobalt and molybdenum concentrated suspension for soybean seed treatment

The concentrated suspension (CS), the basis of Mo trioxide, allows high Mo concentrations and is therefore a technical advance for seed treatment, since it allows the recommendation of the Mo at lower dosage than with the liquid solution formulations (LS). The purpose of this research was to evaluate the efficiency and doses of fertilizer with Mo and Co in concentrated suspension in comparison with liquid solution as well as fertilizers associated with phytohormones, applied in seed treatments, and their effect on soybean yield. Two experiments were carried out in the growing seasons of 2004/2005 and 2005/2006 at the Universidade Federal de Uberlandia (UFU).The first was conducted in an experimental area on the Fazenda Capim Branco, with six treatments and four replications: (1) Mo and Co (CS) - 22 g ha-1 + 1.08 g ha-1; (2) Mo and Co (CS) - 22 g ha-1 + + 1.08 g ha-1 + phytohormone -200 mL ha-1; 3) Mo and Co (LS), 20.7 g ha-1 + 4.13 g ha-1; 4) Mo and Co (LS), 20.7 g ha-1 + 4.13 g ha-1 + phytohormone -200 mL ha-1; (5) + control phytohormone-200 mL ha-1; and (6) control (free of Mo and Co in the seed treatment). The phytohormone consisted of: auxin (11 mg L-1) and cytokynin (0.031 mg L-1). The soybean cultivar Monsoy 8004 was used and a fertilization of 400 kg ha-1 of 02-20-20 NPK fertilizer was applied at sowing. Based on the results of the first experiment, the second was conducted on the Fazenda Floresta do Lobo, in Uberlândia, MG, evaluated in a randomized block design with nine treatments and four replications. The treatments consisted of Mo and Co (g ha-1) doses applied to soybean seeds, as CS formulation (15, 25, 35, 45, 60 and 0.74; 1.23; 1.72; 2.21; 2.95) and LS- (15; 20; 25 and 3.18; 4.25; 5.31), respectively, and the control (free of Mo and Co in the seed treatment). The variety Monarch was used, fertilized with 300 kg ha-1 of NPK fertilizer (03-32-06) at sowing; and 78 kg ha-1 (K2O) in topdressing 30 days after soybean emergence. The Mo and Co doses in the seed treatment with LS and CS resulted in higher soybean yields than in the control, from 20 g ha-1 Mo and 4.25 g ha-1 Co in liquid solution and 35 g ha-1Mo and 1.72 g ha-1 Co in the concentrated suspension.

Local cytokines and clinical symptoms in children with allergic rhinitis after different treatments Gesmar RS Segundo1, Fabíola A Gomes2, Karla P Fernandes1, Ronaldo Alves3, Deise AO Silva3, Ernesto A Taketomi31Department of Pediatrics, 2Department of Nursery, 3Laboratory of Allergy and Clinical Immunology, Universidade Federal de Uberlandia, Uberlandia, BrazilBackground: Therapy for allergic rhinitis aims to control symptoms and improve the quality of life. The treatment of allergic rhinitis includes allergen avoidance, environmental controls, pharmacologic treatment, and specific immunotherapy.Objectives: The aim of this study is to evaluate the clinical changes and the levels of interferon-γ (IFN-γ) and interleukin-5 (IL-5) in nasal lavage fluid from children with allergic rhinitis after different types of pharmacologic treatment (mometasone, montelukast, or desloratadine).Methods: Twenty-four children aged from six to 12 years with moderate persistent allergic rhinitis were randomized into three groups receiving monotherapy treatment over four weeks: nasal corticosteroid (mometasone), leukotriene modifier (montelukast), or antihistamine (desloratadine). The perception of symptom improvement during the medication use was evaluated at the end of the treatment. Samples of nasal lavage fluid were collected before and after treatment for measuring IFN-γ and IL-5 cytokines by ELISA.Results: All parents perceived an improvement in symptoms. Significant enhancement was seen in the mometasone group compared to those with montelukast (P = 0.01) and desloratadine (P = 0.02). No significant differences were found among the three groups in the levels of IL-5 and IFN-γ in nasal fluid at baseline or after treatment. Only the group treated with mometasone showed a slight but significant reduction in IL-5 levels after the treatment period as compared with levels before the treatment (P = 0.0469).Conclusion: The group treated with mometasone showed better improvement of clinical symptoms and a slight reduction in IL-5 levels in the nasal fluid. This may indirectly reflect the relative immunomodulatory effects of the drugs tested.Keywords: allergic rhinitis, cytokines, IL-5, IFN-γ, nasal fluid, desloratadine, mometasone, montelukast, allergy
