title: Genetic parameters for milk traits, somatic cell, and total bacteria count scores in Brazilian Jersey herds

description: ABSTRACT This study aimed to estimate the heritability of milk yield (MY), fat percent (F%), fat yield (FY), protein percent (P%), protein yield (PY), somatic cell score (SCS), and total bacterial count score (TBCS) as well as to estimate the genetic correlations among these traits, using a dataset from 5,918 lactations of Jersey cows in Brazil. The covariance components were estimated by restricted maximum likelihood using the PEST and VCE6 programs. The average values obtained for MY, F%, FY, P%, PY, SCS, and TBCS were 5017.5 kg, 4.3%, 192.3 kg, 3.3%, 173.0 kg, 5.9, and 2.9, respectively, while the heritability values were 0.16, 0.55, 0.18, 0.61, 0.25, 0.21, and 0.08, respectively. The genetic correlations ranged from low to high magnitude, with positive values from 0.06 (TBCS-PY) to 0.72 (FY-PY), and negative values from −0.04 (F%-TBCS) to −0.44 (P%-TBCS). The Jersey breed from Brazil shows genetic variability for all traits analyzed in the present study, and our results suggest that higher genetic gain will be achieved when F% and P% are used as selection criteria. In addition, it is important to use SCS as a selection criterion since the selection for MY and PY may lead to higher SCS or TBCS values, which are undesirable. This was the first study to estimate genetic parameters for milk quality (PY, P%, FY, F%) and udder health (SCS, TBCS) traits in Jersey cows from Brazil. This information is useful for breeding schemes and contributes to better characterize these parameters in tropical region, since few studies were developed with the Jersey cattle in this environment.

title: Influence of the Teachers’ Training Process in the Area Concept Teaching System in Mathematics Pedagogy Students, a Case Study

description: Abstract In the process of training middle school mathematics teachers, which takes place at the Universidad Católica de la Santísima Concepción (UCSC), in the city of Concepción, Chile, we have been interested in observing the process of modifying the mathematics teaching system on a student, from the beginning in a geometry didactics course, until the practicum in a school. To account for the effects of this modification, a classroom management model based on the Theory of Didactic Situations was proposed, which allowed us to plan a geometry class to teach the area concept of a quadrilateral. To account for the teaching work carried out by the student in two exclusive moments; in the university classroom to their classmates in the role of a school student, and in the school when the same student as a teacher teaches real students. The teaching process carried out by the student was observed and contrasted with theoretical elements of the Mathematical Work Space (MWS).

title: Pulp canal obliteration after traumatic injuries in permanent teeth – scientific fact or fiction?

description: Abstract: Pulp canal obliteration (PCO) is a frequent finding associated with pulpal revascularization after luxation injuries of young permanent teeth. The underlying mechanisms of PCO are still unclear, and no experimental scientific evidence is available, except the results of a single histopathological study. The lack of sound knowledge concerning this process gives rise to controversies, including the most suitable denomination. More than a mere semantic question, the denomination is an important issue, because it reflects the nature of this process, and directly impacts the treatment plan decision. The hypothesis that accelerated dentin deposition is related to the loss of neural control over odontoblastic secretory activity is well accepted, but demands further supportive studies. PCO is seen radiographically as a rapid narrowing of pulp canal space, whereas common clinical features are yellow crown discoloration and a lower or non-response to sensibility tests. Late development of pulp necrosis and periapical disease are rare complications after PCO, rendering prophylactic endodontic intervention useless. Indeed, yellowish or gray crown discoloration may pose a challenge to clinicians, and may demand endodontic intervention to help restore aesthetics. This literature review was conducted to discuss currently available information concerning PCO after traumatic dental injuries (TDI), and was gathered according to three topics: I) physiopathology of PCO after TDI; II) frequency and predictors of pulpal healing induced by PCO; and III) clinical findings related to PCO. Review articles, original studies and case reports were included aiming to support clinical decisions during the follow-up of teeth with PCO, and highlight future research strategies.

title: How biomechanics can affect the endodontic treated teeth and their restorative procedures?

description: Abstract: Endodontic treatment is a common dental procedure used for treating teeth which the pulp tissue has become irreversibly inflamed or necrotic as a result of the carious process or dental trauma. This procedure which involves mechanical and chemical preparation of root canal may affect several mechanical and physical properties of the tooth structure. The endodontic treatment can also influence the longevity of the rehabilitation of endodontically treated teeth and biomechanics during the oral function. For restoring endodontically treated teeth several factor and clinical decisions should be observed. The decision of the fiberglass post usage and the restorative materials are related to several factors such as the quantity and quality of remaining dental structure, presence of ferrule, post cementation length and final coronal restoration. In this review, the authors will address the effect of the endodontic treatment procedures on canal shape and mechanical properties of a tooth, and also discuss the parameters and the biomechanical principles of root canal treated teeth.

title: Analysis of an Early Elementary School Teacher Reflections Participating in the Education Observatory about her Practice

description: Abstract This article aims to present the analysis of the reflections, regarding the practice itself, of a teacher participating in a formative process regarding the fractions subject, with emphasis on a quotient situation involving equivalence of fractions. This study was developed under the Education Observatory Program. In order to do so, we observed the information produced in four moments and attempted to analyze, in the light of Schön's theory, mainly the reflection on the action, the interpretations that the teacher made of her professional practice; and, based on Serrazina, the relations of her knowledge with the reflections she made. Throughout the development process, we noticed that the establishment of a space for collective discussions helped (re)-signify the knowledge to teach fractions. We believe that the development course has contributed to enlarge the teacher's reflection, guiding her to realize and work on her weaknesses, and to reinforce her strengths. The latter were enlarged by the investigative attitude about the diversity of methodological procedures that can be used in when teaching fractions.

title: The changing course of the Amazon River in the Neogene: center stage for Neotropical diversification

description: ABSTRACT We review geological evidence on the origin of the modern transcontinental Amazon River, and the paleogeographic history of riverine connections among the principal sedimentary basins of northern South America through the Neogene. Data are reviewed from new geochronological datasets using radiogenic and stable isotopes, and from traditional geochronological methods, including sedimentology, structural mapping, sonic and seismic logging, and biostratigraphy. The modern Amazon River and the continental-scale Amazon drainage basin were assembled during the late Miocene and Pliocene, via some of the largest purported river capture events in Earth history. Andean sediments are first recorded in the Amazon Fan at about 10.1-9.4 Ma, with a large increase in sedimentation at about 4.5 Ma. The transcontinental Amazon River therefore formed over a period of about 4.9-5.6 million years, by means of several river capture events. The origins of the modern Amazon River are hypothesized to be linked with that of mega-wetland landscapes of tropical South America (e.g. várzeas, pantanals, seasonally flooded savannahs). Mega-wetlands have persisted over about 10% northern South America under different configurations for &gt;15 million years. Although the paleogeographic reconstructions presented are simplistic and coarse-grained, they are offered to inspire the collection and analysis of new sedimentological and geochronological datasets.

title: Experiencing suicide in the family: from mourning to the quest for overcoming

description: ABSTRACT Objective: to understand the family’s experience of losing a family member by suicide. Method: study with qualitative approach with reference of the Constructivist Grounded Theory. The theoretical sample consisted of 20 participants, among health professionals and family members of people who committed suicide. Data were collected through intensive and coded interviews from initial and focused coding. Results: three categories were obtained: Being in a “state of shock”; Living with the suffering and effects of the loss of the family member; and, Rebuilding life. From the articulation of these categories emerged the phenomenon: “Experiencing the loss of a family member by suicide: from mourning to the quest for overcoming”. Final considerations: each category represents a stage in the family’s experience of losing a family member by suicide. The results provide support for suicide prevention and postvention actions developed by health professionals.

title: HIGH-FLOW NASAL CANNULA POST-TRACHEAL EXTUBATION IN A CHILD WITH UPPER AIRWAY OBSTRUCTION: CASE REPORT

description: ABSTRACT Objective: To report a case of a patient who required tracheal intubation in a pediatric emergency department due to acute laryngitis and that, after the planned extubation, has successfully used the high-flow nasal cannula, which possibly prevented extubation failure. Case description: A male 8-month-old child was admitted to the pediatric emergency room with acute respiratory distress due to a high airway obstruction secondary to severe acute laryngitis. He was immediately intubated and referred to the pediatric intensive care unit. He presented extubation failure due to a significant laryngeal edema evidenced by bronchoscopy. In the second attempt to extubate, he presented respiratory distress, but, after the use of the high-flow nasal cannula, he became stable, reducing the heart and respiratory frequencies, and the extubation was successful. Comments: The use of the high-flow nasal cannula was effective and presented good response in this patient with acute laryngitis, suggesting that it is a possible adjuvant for the treatment, avoiding worsening respiratory conditions and the need for reintubation.

title: Association of morphometric measurements with morphologic scores of Criollo horses at Freio de Ouro: a path analysis

description: ABSTRACT This study used path analysis to establish the direct, indirect, and total effects of body linear and angular measurements on subjective morphological scores of the 247 Criollo horses that participated in their most important performance event, Freio de Ouro, in 2012. Freio de Ouro is the only event of the Criollo breed that considers morphology. Measurements of wither height, thoracic girth, cannon bone girth, body length, metatarsus length, croup length, shoulder width, head length, neck length, and upper neck girth, and the angles of rump, shoulder, and hock were taken. These morphometric measurements collectively explained 83% of the variation in morphological score. The measurements with the greatest total effects on score were neck length (correlation coefficient = 0.2300), upper neck girth (0.2100), angle of rump (–0.1600), thoracic girth (0.1400), shoulder width (0.1400), body length (0.1100), croup length (0.1100), shoulder angle (–0.1100), and metatarsus length (0.1000). These results mean that these variables have the highest association with morphological evaluation by referees. This is the first scientific study of the correlation of morphological measurements with judge evaluation in Criollo horses.
