title: Reaction of popcorn lines (s7) cultivated in distinct phosphorus levels to Bipolaris maydis infection

description: ABSTRACT Popcorn culture is highly susceptible to helminthosporiosis (Bipolaris maydis) (h-Bm). The genetic breeding of this culture should prioritize resistance to h-Bm and develop cultivars that offer greater crop sustainability, especially in soils with phosphorus (P) scarcity. P-mineral is usually supplied to maize culture by the application of phosphate fertilizers, which are produced from mineral sources rich in P, the natural reserves of which will be depleted in the medium term. With the aim of selecting popcorn genotypes resistant to h-Bm and with higher P utilization capacity, the present study evaluated h-Bm incidence and severity for 25 popcorn lines (S7) cultivated under high and low phosphorus conditions. There was a significant interaction between genotype (lines) and P fertilization for h-Bm resistance, expressed as disease severity values in the first ear leaf. There was genetic variability for disease resistance. The incidence analysis identifies the lines L-65 L-69, L-70 and L-76 as potentially resistant genotypes, presenting low mean values of h-Bm. The severity analysis, however, presents L-69, L-76, P-3 and P-7 genotypes as potentially resistant in environments with fertilization and without fertilization. The obtained data show that the lines L-69 and L-76 had the best resistance performance in both environments. The genetic resistance to h-Bm can somehow correlate with the response to P fertilization at planting in soils with low natural fertility.

title: Addition of zirconium oxide to Biodentine increases radiopacity and does not alter its physicochemical and biological properties

description: Abstract Objectives: To evaluate the radiopacity of Biodentine (BD) and BD associated with 15% calcium tungstate (BDCaWO4) or zirconium oxide (BDZrO2), by using conventional and digital radiography systems, and their physicochemical and biological properties. Materials and Methods: Radiopacity was evaluated by taking radiographs of cement specimens (n=8) using occlusal film, photostimulable phosphor plates or digital sensors. Solubility, setting time, pH, cytocompatibility and osteogenic potential were also evaluated. Data were analyzed using one-way ANOVA and Tukey post-test or two-way ANOVA and Bonferroni post-test (α=0.05). Results: BD radiopacity was lower than 3 mm Al, while BD ZrO2 and BD CaWO4 radiopacity was higher than 3 mm Al in all radiography systems. The cements showed low solubility, except for BDCaWO4. All cements showed alkaline pH and setting time lower than 34 minutes. MTT and NR assays revealed that cements had greater or similar cytocompatibility in comparison with control. The ALP activity in all groups was similar or greater than the control. All cements induced greater production of mineralized nodules than control. Conclusions: Addition of 15% ZrO2 or CaWO4 was sufficient to increase the radiopacity of BD to values higher than 3 mm Al. BD associated with radiopacifiers showed suitable properties of setting time, pH and solubility, except for BDCaWO4, which showed the highest solubility. All cements had cytocompatibility and potential to induce mineralization in Saos-2 cells. The results showed that adding 15% ZrO2 increases the radiopacity of BD, allowing its radiography detection without altering its physicochemical and biological properties.

title: Diversity of clinical, radiographic and genealogical findings in 41 families with amelogenesis imperfecta

description: Abstract Amelogenesis imperfecta (AI) is a group of enamel development disorders that alter the structure and chemical composition of the tissue. There is great variability in the clinical presentation; according to Witkop, AI can be categorized into 14 subtypes, which makes its diagnosis extremely complex. Objective: This study aimed to describe and determine the frequency of clinical and radiographic features and inheritance patterns found in 41 Chilean families diagnosed with diverse types of AI. Material and Methods: We analyzed the clinical records, photographs, pedigrees and radiographs of 121 individuals recruited between 2003 and 2016. All of the information was included in a database that was analyzed using the application Stata 14. Results: The 72 affected individuals had average age of 16 years, and no sex association with the presence of AI was found. The most frequent clinical subtypes were as follows: 43% hypomature, 25% hypoplastic, 21% hypomature/hypoplastic, 7% hypocalcified and 4% hypocalcified/hypoplastic. The number of severely affected teeth was 22, which occurred in the patients with hypocalcified and hypocalcified/hypoplasic AI who presented the highest number of damaged teeth. Caries and periodontal disease were found in 47 and 32% of the patients, respectively. Malocclusions were observed in 43% of the individuals with AI, with open bite being the most frequent. Radiographically, the thickness of the enamel decreased in 51% of the patients, and 80% showed decreased radiopacity of the enamel compared to that of dentin. Autosomal dominant inheritance pattern was found in 37% of the families with hypoplastic AI, and autosomal recessive pattern was present in 56% of the other clinical subtypes, but more frequently in those affected with hypomature and hypocalcified AI. Conclusion: Of the five clinical subtypes, autosomal recessive hypomature, autosomal dominant hypoplastic and autosomal recessive hypomature/hypoplastic AI were the most prevalent subtypes in this group.

title: Random-start controlled ovarian stimulation for emergency fertility preservation in a patient with myelodysplastic syndrome: a case report

description: This study reports a case of a gonadotropin-releasing hormone agonist trigger in a young female with myelodysplastic syndrome (MDS) who underwent fertility preservation using random-start controlled ovarian stimulation. This method involves the stimulation of the ovary regardless of a patient's menstrual-cycle phase. A review of the related literature is also provided. A 17-year-old patient was diagnosed with MDS and required initiation of peripheral blood stem cell transplantation within a maximum of 3 weeks and was in the luteal phase of the menstrual cycle when the possibility of attempting preservation of fertility was presented to her. She opted for a random-start controlled ovarian stimulation with gonadotropins. With successful hemorrhagic prophylaxis, 17 oocytes were retrieved including 10 mature and 7 immature oocytes. Of the immature oocytes, 3 were successfully matured in vitro and a vitrification protocol was used to freeze the 13 mature oocytes.

title: Adductor pollicis muscle as predictor of malnutrition in surgical patients

description: Background - In the compromised nutritional status, there is excessive skeletal muscle loss and decreased inflammatory response, contributing to increased morbidity and mortality and length of stay. Aim: To estimate the prevalence of malnutrition by measuring adductor pollicis muscle using cutoffs for surgical patients suggested in the literature. Methods: Cross-sectional study with 151 patients scheduled for elective surgical procedure. Nutritional assessment was performed by classical anthropometric measurements: arm circumference, triceps skinfold thickness, arm muscle circumference, corrected arm muscle area, BMI and percentage of weight loss and the extent of the adductor pollicis muscle in both hands. Results: The prevalence of malnutrition in patients was high. A significant association between nutritional diagnosis according to the measures of adductor pollicis muscle and arm circumference, BMI and triceps skinfold thickness but there was no association with arm muscular circumference, arm muscular area or percentage of weight loss. Conclusion: The adductor pollicis muscle has proved to be a good method to diagnose muscle depletion and malnutrition in surgical patients.

title: CULTIVATION OF Chlorella vulgaris IN MEDIUM SUPPLEMENTED WITH DESALINATION CONCENTRATE GROWN IN A PILOT-SCALE OPEN RACEWAY

description: ABSTRACT In this study, we investigated the outdoor production of a microalga C. vulgaris cultured in two different media under autotrophic cultivation: Bold Basal Medium (BBM) as the control and BBM supplemented with desalination concentrate (BBM + DC) using open raceway ponds (8 m2). Data were collected on the growth, biomass productivity and biochemical composition. The culture developed in BBM + DC showed a biomass productivity of 6.8 g m-2 day-1, while for the BBM control it was 8.5 g m-2 day-1. Intracellular protein was the main algal component (~28.6%), followed by carbohydrate + fiber (~26.0%) and lipids (~5.0%). The predominant fatty acids were mainly α-linolenic (~19.5%), palmitic (~16.5%) and linoleic (~10.0%) acids. This study demonstrates the feasibility of culturing C. vulgaris in an alternative medium based on DC in order to valorize the desalination wastewater through its application to algal mass production.

title: The effects of xanthan gum on equine sperm quality during cooling storage

description: ABSTRACT This study was designed to evaluate the possible benefits of adding xanthan gum to a standard extender for equine through in vitro analyzes of sperm quality. Semen was collected four times from five different stallions (n= 20 samples) and subjected to cooled storage under different conditions: control (only standard extender) and three different concentrations of xanthan gum (0.01%, 0.12%, and 0.25%) supplemented to the extenders. Sperm parameters, such as motility, mitochondrial functionality, and membrane, acrosome, and DNA integrity were measured after 0h, 24h, 48h, and 72h of sperm storage at 5ºC. Our observations indicated that sperm motility declined with longer cooling period with the 0.25% xanthan gum supplementation group compared with the control group. Other parameters, such as mitochondrial functionality and membrane and acrosome integrity also declined for all treatments during storage; however, no differences were observed between xanthan gum and control groups. DNA integrity did not significantly change during the storage. In conclusion, the addition of xanthan gum to equine semen extender is not harmful to the sperm structure, despite reducing the sperm motility.

title: Serum biochemical profile of neonatal buffalo calves

description: ABSTRACT Serum blood samples from 50 Murrah buffalo calves were examined in this study. The animals were allocated into three groups according to the number of parturitions of their mothers: G1 (n= 15) calves from primiparous buffaloes, G2 (n= 19) calves from buffaloes with two to four parturitions, and G3 (n= 16) calves from buffaloes with five or more parturitions. Blood samples were taken at birth, before colostrum ingestion, at 24h, 48h, and 72h after birth, and at 7, 14, 21, and 30 days after birth for determination of levels of gammaglutamyl transferase (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), creatine kinase, total protein, albumin, globulins (including immunoglobulin G), iron, total calcium, ionized calcium, phosphorus, sodium, and potassium. The age of the calves was found to influence all of the biochemical parameters, with the exception of ionized calcium and potassium in the calves in groups G1 and G3. The calving order was found to influence AST, GGT, total protein, albumin, and globulins, including IgG. The high serum ALP activity in the first two days after birth indicates that measurement of the levels of this enzyme may be used as an indirect method of assessing passive immunity transfer.

title: Epidemiological profile of bovine and swine cysticercosis in three regions of Minas Gerais State, Brazil

description: ABSTRACT In order to evaluate the epidemiological situation of porcine and bovine cysticercosis in the rural area of five municipalities, distributed in three different regions of the state of Minas Gerais, Brazil, the prevalence of bovine and porcine cysticercosis was determined in the rural properties as well as the main risk factors that may favor the transmission and maintenance of the disease in these properties. The research covered 388 farms, located in 91 different rural communities, with 1,792 samples of bovine blood and 554 of swine collected. In addition to the evaluation of these laboratory samples (indirect ELISA and Imunoblot), the data obtained from the application of a questionnaire for each property were also analyzed, with information on socioeconomic, hygienic-sanitary and animal-related conditions. The prevalence of cysticercosis ranged from 0.3 to 5.9% in cattle and from 0 to 2.8% in the pigs raised in these municipalities. Among the main risk factors for transmission of bovine cysticercosis were the source of water consumed, the origin of the meat, the nature of the municipality and the region. Regarding the pigs, risk factors were the sewage disposal and animal management system.

title: Survey of dental diseases in Crioulo breed horses reared in an extensive farming system

description: ABSTRACT The present study aimed to identify and quantify dental diseases in Crioulo horses reared exclusively under extensive farming conditions. In total, 254 Crioulo horses were evaluated, that were reared exclusively in native pastures with predominantly Eragrostis plana (Annoni grass). The animals were divided into three groups according to age: three to five years (G1), six to 12 years (G2), and 13 to 26 years (G3). In total, 46.1% of the animals in G1, 63.8% in G2, and 82.3% in G3 had two or more incisor disorders; 37.5% in G1, 52.5% in G2 and 45.5% in G3 had two or more disease findings in the canines; and 28.9% in G1, 35.4% in G2, and 64.7% in G3 had four or more disease findings in the second, third, and fourth premolars and molars. However, dental calculus was observed in 90.5% of G2 animals, whereas in G3, the occurrence rate of excessive enamel points and calculus was 82.4%. Although all of the horses studied were reared in an extensive farming system, dental changes were very common in the Crioulo breed reared under these management conditions.

title: Morphometric analysis of feedforward pathways from the primary somatosensory area (S1) of rats

description: We used biotinylated dextran amine (BDA) to anterogradely label individual axons projecting from primary somatosensory cortex (S1) to four different cortical areas in rats. A major goal was to determine whether axon terminals in these target areas shared morphometric similarities based on the shape of individual terminal arbors and the density of two bouton types: en passant (Bp) and terminaux (Bt). Evidence from tridimensional reconstructions of isolated axon terminal fragments (n=111) did support a degree of morphological heterogeneity establishing two broad groups of axon terminals. Morphological parameters associated with the complexity of terminal arbors and the proportion of beaded Bp vs stalked Bt were found to differ significantly in these two groups following a discriminant function statistical analysis across axon fragments. Interestingly, both groups occurred in all four target areas, possibly consistent with a commonality of presynaptic processing of tactile information. These findings lay the ground for additional work aiming to investigate synaptic function at the single bouton level and see how this might be associated with emerging properties in postsynaptic targets.
