title: Serological and molecular investigation of Leishmania spp. infection in cats from an area endemic for canine and human leishmaniasis in Northeast Brazil

description: Abstract The aim of this study was to investigate the occurrence of Leishmania spp. antibodies, and its association with feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV), in domestic cats from an area endemic for canine and human leishmaniasis in Rio Grande do Norte State, Brazil. Ninety-one cats were subjected to a complete clinical exam, and blood samples were collected. An epidemiological questionnaire was used to investigate the risk factors. IgG anti-Leishmania spp. antibodies were detected by immunofluorescence antibody test (IFAT), with a cut-off value of 1:40. Polymerase chain reaction (PCR) was performed to detect genetic material of Leishmania spp. in the blood samples. The presence of antibodies against FIV and antigens of FeLV was evaluated using an immunochromatographic test. Seropositivity for Leishmania spp., FIV, and FeLV was observed in 14/91 (15.38%), 26/91 (28.57%), and 3/91 (3.29%) cats, respectively. All samples gave negative results on PCR analysis. Based on these data, no significant statistical association was observed between seropositivity for Leishmania spp., and sex, age, presence of clinical signs, evaluated risk factors, and positivity for retroviruses. These findings demonstrated for the first time that cats from Mossoró, Rio Grande do Norte, are being exposed to this zoonosis and might be part of the epidemiological chain of transmission of visceral leishmaniasis.

title: A new species of Coccoloba P. Browne (Polygonaceae) from the Brazilian Amazon with exceptionally large leaves

description: ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic distribution and conservation status of the species.

title: Biochemical profile of Mangalarga Marchador mares during the last third of pregnancy, foaling and lactation

description: ABSTRACT: Adaptive changes in metabolism may occur under specific physiological conditions, being necessary the knowledge of the biochemical constituents that can undergo variations during the sixty days before foaling, until the first sixty days of lactation. The present study aimed to identify and evaluate the biochemical profile of Mangalarga Marchador mares during the last third of pregnancy, foaling and lactation. For this, 48 mares were used, which formed a maintenance group (MG), composed of non-pregnant mares and an experimental group, called the transition group (TG), formed by pregnant mares. Blood samples were collected at the following times: MG was evaluated in a single time (beginning of all collections); TG was evaluated in seven times [T-60, T-30, T-15 (days before foaling), T0 (first six hours after foaling), T15, T30, T60 (days after foaling)]. All animals were submitted to biochemical analysis, in which the concentrations of total calcium, chloride, phosphorus, magnesium, sodium, potassium, uric acid, creatinine, and urea were measured. The two groups differed significantly (P&lt;0.05) in calcium, magnesium, sodium, potassium, creatinine, uric acid and urea concentration. Variation between times was also observed for these compounds. However, chloride and phosphorus did not differ between MG and TG. It was concluded that the last third of pregnancy, foaling and lactation exerts major influence on the biochemical constituents of blood through adjustments to maintain homeostasis in mares.

title: Calorimetry Experiments in University Courses

description: Abstract In this work we investigated in detail a calorimetry experiment often executed in university courses. The motivation was the consistent occurrence of issues regarding the determination of the specific heat of a test part by the students, which often obtained negative values. We explored many variations of the “standard” method, as we called it, which consisted of measuring the specific heat of a metal part by having it reach the thermal equilibrium with a water sample within a simple calorimeter. Besides this method, we also explored an alternative one based on the Joule effect. The results show that one of the variations of the standard method to be the one that yields the best results. However, the alternative method obtained better results than some of the variations of the standard method and is also richer in the exploration of physical concepts and data analysis.

title: Immune response of teleost fish to helminth parasite infection

description: Abstract Fish immune systems have become the subject of several studies due to the growing development of aquaculture and fisheries, and the demand for healthy produce for human consumption. Among the parasites responsible for diseases in fish farming, helminths stand out because they cause infections in farmed fish and decrease food conversion, zootechnical performance and meat quality. In the present review, the components that participate in the innate and adaptive immune responses of teleost fish that have so far been described are presented in order to summarize the defenses that these hosts have recourse to, in combating different groups of helminth parasites.

title: Inferring mating system parameters in forage peanut, Arachis pintoi, for Brazilian Amazon conditions

description: ABSTRACT The search for alternatives to increase productivity and sustainability of livestock production in the Amazon region without increasing deforestation is challenging. Mixed pastures of grasses with forage peanut (Arachis pintoi) have shown positive economic impacts. However, gaps in the knowledge of the reproductive biology of A. pintoi have limited the development of new cultivars adapted to the environmental variations in the Brazilian Amazon. Pasture consortiums of Brachiaria humidicola with forage peanuts (cv. Mandobi) resulted in a 42% increase in weight gain productivity. New cultivars better adapted to the Amazon climate should bring even greater gains. We evaluated the mating system in twenty A. pintoi accessions, and approximately 40 offspring per accession genotyped with eight microsatellites (or markers). The parameters of genetic diversity and inbreeding, the outcrossing rate and coancestry were calculated. The observed heterozygosity was significantly higher and the fixation index was significantly lower in adults compared with the offspring. The crossing rate was variable among genotypes (2 to 80%), and the mean outcrossing rate was 36%. These results indicate that pollinator presence in pastures can influence gene flow in A. pintoi more than expected. Arachis pintoi presented a mixed mating system with a predominance of selfing, and families presented inbreeding and different levels of relatedness. New strategies of genotype conservation are needed to avoid pollinator-mediated crossing between accessions.

title: Resistance of the stable fly, Stomoxys calcitrans (Diptera: Muscidae), to cypermethrin in outbreak areas in Midwestern Brazil

description: Abstract Population explosions of the stable fly (Stomoxys calcitrans) have become a serious concern for livestock producers near sugarcane mills in some regions of Brazil due to the insect’s massive reproduction on sugarcane byproducts and waste. Despite the limited efficiency of insecticides for controlling stable fly outbreaks, producers still rely on chemical control to mitigate the alarming infestations in affected areas. This study evaluated the susceptibility of S. calcitrans populations to cypermethrin in the state of Mato Grosso do Sul, Brazil. Stable flies were tested from three field populations and two colonies, established from flies previously collected at sugarcane mills. Wild flies were collected with Nzi traps in areas of sugarcane plantations. Both wild and colonized flies were exposed to eleven concentrations of cypermethrin in impregnated filter paper bioassays. All the populations proved to be resistant to cypermethrin, with resistance factors among field populations ranging from 6.8 to 38.6. The intensive use of insecticides has led to the development of pyrethroid resistance in stable fly populations in the proximities of sugarcane mills in the state of Mato Grosso do Sul.

title: COMPARISON OF LCP AND INTRAMEDULLARY NAIL OSTEOSYNTHESIS IN CALCANEAL FRACTURES

description: ABSTRACT Objective: This study compared groups of patients with calcaneal fractures of Sanders types II and III. One group was treated with ORIF using an LCP (plate), while the second was treated with a minimally invasive method using a C-Nail. Methods: The study included 217 patients in the ORIF group and 19 patients in the minimally invasive nail osteosynthesis group. Results: In the LCP group, the outcomes were excellent for 35.7% of the patients; good, 38.9%; satisfactory, 19.7%; and poor, 5.7%. In the C-Nail group, the outcomes were excellent for 36.9% of the patients; good; 31.6%; satisfactory, 21%; and poor, 10.2%. The mean values of the restoration of Böhler's angle from post-injury were 6.8° to 32.3° in the LCP group and 7.1° to 33.3° in the C-Nail group. After 12 months, there was only a minimal decrease in Böhler's angle to 29.2° in both the LCP and C-Nail groups. Conclusion: The outcomes obtained with C-Nail fixation are statistically identical to those obtained with LCP fixation. We conclude that osteosynthesis with a C-Nail is suitable as the first-choice treatment for Sanders types II and III fractures. Level of evidence IV, retrospective observational study.

title: Culture of school material in the radiophonic schools in Bragança: permanencies and pedagogical innovations (1960-1970)

description: ABSTRACT The present article aims to analyse the school material culture in radiophonic schools of Bragança and the creation of permanencies and pedagogical innovations in the period from 1960 to 1970. We used the New Cultural History approach as the method to analyse the use of school materials and the education representations of subjects on these materials in the daily life of classrooms. Three types of schools were identified: (i) a school that operated in the house of the monitor; (ii) another in a straw shed; and (iii) one that operated on a municipal school. The school material culture, in this school institution, consists of the following materials: writing materials (chalk and pencil with eraser); materials of writing support (blackboard, poster, notebooks, and blank sheets of paper); furniture (rough wooden tables and rectangular wooden benches); reading materials (short texts and reports); lighting materials (lamps, pressure lamps, and aladins); costumes of the students (handmade chita and cotton clothing); protection materials (Inajá and Babassu thatches); material of communication and teaching (known as captive radio). These materials made it possible to identify the permanencies and pedagogical innovations. We concluded that the school materials produced critical, emancipatory, and evangelizing representations whose purpose was to alphabetize the youth and adults of the radiophonic schools in Bragança, State of Pará.

title: Analysis of the effectiveness of transepithelial crosslinking in patients with keratoconus

description: Abstract Objective: To evaluate the clinical results of Transepithelial Crosslinking (CXL) by analyzing its efficacy in patients with progressive keratoconus. Methods: Retrospective cross-sectional study with 49 eyes and 37 patients aged 10 to 50 years submitted to the CXL technique in 2017 at the Instituto Panamericano da Visão, in Goiânia, Goiás, Brazil. The Avedro KXL system was programmed in pulsed mode with interval (1/1 second), using 45 mW/cm² with 7.2 J and 0.25% riboflavin solution of Avedro with irradiated corneas for 8 minutes. Data were collected: sex, age, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), astigmatism, pachymetry at the thinnest point and keratometric astigmatism in the preoperative and postoperative periods at 1, 6 and 12 months. The Kolmogorov-Smirnov, Pearson's Chi-square, Friedman, Dunnett, and the Spearman correlation were used. Results: Twenty-three patients (62.2%) were female and 14 (37.8%) male. The mean age was 27.89 ± 10.89 years. The UDVA and CDVA significantly improved in the preoperative period in relation to 1 month (p = 0.01) and (p &lt;0.001), 6 months (p &lt;0.001 both) and 12 months (p &lt;0.001 both). Astigmatism significantly reduced preoperatively in relation to 6 months (p = 0.02) and 12 months (p = 0.02). The pachymetry at the thinnest point remained constant in the period (p = 0.95). The difference between k2 and k1 (keratometric astigmatism) showed a significant reduction in the preoperative period in relation to 1 month (p = 0.01). Conclusion: The CXL technique was safe and effective in the treatment and stagnation of the disease in patients with progressive keratoconus.

title: CHRONIC CONSUMPTION OF ALCOHOL ADVERSELY AFFECTS THE BONE OF YOUNG RATS

description: ABSTRACT Objective: To assess the effect of chronic alcohol consumption on the longitudinal growth of the tibia and bone quality parameters in young rats under an experimental setup. METHODS: The control (n=10) rats received only water. The ethanol (n=10) rats received ethyl alcohol at concentrations established in the protocol for the induction of chronic alcohol consumption. The blood samples were immediately collected via cardiac puncture and processed to evaluate the levels of alkaline phosphatase by automated spectrophotometry. Following blood sample collection, both tibias were dissected, and weighed; the tibial length was measured., and the samples were stored in a freezer for future analysis of the bone mineral content and mechanical resistance, known as maximal load and stiffness. RESULTS: Compromised bone health, with a 35.3% decrease in the serum alkaline phosphatase levels (p &lt; 0.01), a 10% decrease in the tibial mass (p &lt; 0.05), and a 5.3% decrease in the tibial length (p &lt; 0.0001) were noted. Furthermore, a 10% decrease in the bone mineral density was observed (p &lt; 0.01), which led to a 17.2% decrease in the maximum strength (p &lt; 0.01) and 22.6% decrease in stiffness (p &lt; 0.001). CONCLUSION: Chronic consumption of alcohol affected the bones of young rats, making them weaker and osteopenic. In addition, the long bones were shorter, suggesting interference with growth. Level of Evidence III, Case Control Study.
