The Effects of Short Term Intracanal Medicaments on the Fracture Resistance of Root in Pulp Revitalization Procedure

Introduction: The objective of this study was to evaluate the effects of short term intracanal medicaments on the fracture resistance of root in simulated necrotic immature teeth in pulp revitalization procedure. Methods and Materials: Bovine teeth (n=180) were selected, sectioned coronally and apically and then, internally fragilized. Intracanal medicament groups were arranged as follows: “Triple Antibiotic Paste” (TAP) group (n=60), “Calcium Hydroxide” (CH) group (n=60) and the control group (n=60). No medication was used in the control group. Fracture resistance tests were performed after 7, 14, and 21 days. At allocated intervals, 20 teeth from each group had fractured. The Kruskal-Wallis and Mann-Whitney tests were performed to verify the effects of the employed medicaments at each time point. Friedman test and Wilcoxon signed-rank test were also performed to verify the association between time and fracture resistance. The level of significance was set at 0.05. Results: After 7 days, there was no statistical difference between groups (P=0.376). Intragroup analysis revealed that, after 21 days, the TAP group (P=0.015) and the CH group (P=0.006) presented a statically significant reduction in fracture resistance comparison with 7 days. Statistical difference was not verified for the control group after 7, 14 and 21 days (P=0.25). There was no statistical difference between CH group and the control group after 7, 14 and 21 days (P>0.05). The reduction was significant for TAP after 14 and 21 days (P=0.018, P=0.033 Respectively). Conclusions: This in vitro study showed that the duration at which TAP and CH remained in the root canal influenced the fracture resistance of bovine teeth with simulated incomplete root formation.Keywords: Calcium Hydroxide; Endodontics; Regeneration; Triple Antibiotic Past

Farelo de soja fermentado em rações para frangos de corte / Fermented soybean meal in broiler feed

Foi avaliado o uso do farelo de soja fermentado (FSF), PepSoyGen® (Nutraferma), no desempenho produtivo, metabolizabilidade e na morfometria intestinal de frangos de corte. No desempenho, foram utilizados 960 pintos, machos e fêmeas, de 1 dia distribuídos em 40 boxes com 24 animais cada (12 machos e 12 fêmeas), num delineamento inteiramente casualizado, dispostos em oito repetições de cinco tratamentos: T1 - controle sem adição de FSF; T2 - adição de 0,5% de FSF; T3 - adição de 1,0% de FSF; T4: adição de 1,5% de FSF; T5 - adição de 2,0% de FSF. Para metabolizabilidade das rações foi utilizado um total de 400 pintos machos de corte de 14 dias de idade, distribuídos de forma inteiramente casualizada em 40 gaiolas metabólicas. O experimento consistiu dos mesmos cinco tratamentos, com oito repetições e 10 aves/repetição (gaiola). Não foi observada diferença significativa para as variáveis de desempenho e morfometria intestinal assim como para a metabolizabilidade das rações. Conclui-se que farelo de soja fermentado em rações para frangos de corte não interferiu no desempenho produtivo, rendimento da carcaça e suas características, no peso relativo dos órgãos, na metabolizabilidade da ração e na morfometria do trato intestinal

Orthodromic Atrioventricular Tachycardia in Wolff-Parkinson-White Syndrome with Two Accessory Pathways Participation during the Same AVT

Case report of a 49-year-old patient with Wolff-Parkinson-White syndrome, very symptomatic, with apparent parahisian pathway who, during an electrophysiological study, presented orthodromic atrioventricular tachycardia, featuring two accessory pathways, retrogradely, the parahisian pathway and a hidden left posterolateral pathway, during the same tachycardia, alternating the retrograde pathway of tachycardia without interruption

Multifractal characterization as a function of timescale in the light curves with planetary signal observed by the Kepler mission: Caracterização multifractal como uma função da escala de tempo em curvas de luz com sinal planetário observada pela missão Kepler

We investigate the evolution of five multifractal indicators of the Kepler Mission light curves of the moderately young Sun-like Kepler-30 star accompanied by a three-planet system. We focus not only on the fact that the rotational modulation has multifractality properties but also on some studies on these properties based on scale. Then, we systematically investigate the dynamic behaviors of the small and large fluctuations in two types of light curves (PDC and SAP). Those fluctuations indicate that the properties of stellar noise and rotation modulation are highlighted when we apply the Multifractal Detrended Moving Average (MFDMA) algorithm. Our results also demonstrated that the multifractality of the light curve is due to both long-range correlation and broad probability density function, but the main source of multifractality is the long-range correlation. This new approach can be used to develop theoretical and computational models for various stellar magnetic activity-related phenomena and their interactions with the planets, and it can greatly simplify spot modeling from current TESS and future PLATO data

AUTOMATIC METHOD FOR GLAUCOMA CLASSIFICATION USING TEXTURE ANALYSIS, XGBOOST AND GRID SEARCH

Glaucoma is an irreversible pathology, generated by increased intraocular pressure. Early detection is critical and can pre- vent total vision loss. Clinical examinations are commonly used to detect the disease. Still, the time and cost of identi- fication is quite high. This paper presents a computational methodology that aims to assist specialists in the discov- ery of glaucoma through Computer Vision techniques. The proposed methodology consists in the application of several texture descriptors combined with a parameter optimiza- tion done through Grid search with the XGBoost classifier. A result was obtained with accuracy of 82.37% and ROC of 82.08%

a study from ecological theory and social network analysis perspective

The objective of the present study was to analyze and compare the setter's decision-making (DM) in the offensive construction of the side-out (attack from the reception) in high-level men's volleyball. The sample consisted of the analysis of 132 games of the Brazilian men's volleyball Super-League 2021/2022, with 22 games for each team. The results showed that the eigenvector values were higher for setting to position 3, central attacker next to the setter, simple block, and obtaining the attack point. In addition, the setter's DM was similar between teams, suggesting that the game strategies aim to provide subsidies for the setter to make the decisions according to the game context in a flexible way and generate benefits for the attackers about the number of blockers, being that under ideal conditions and due to the lifter's correct choices in distribution, central blockers avoid anticipating the setting, and this fact allows the conditions of a single block or double-broken blocks in most cases. As a practical application, setting for the central attacker in position 3 becomes an interesting option for point acquisition and is capable of influencing the number of blockers, as well as the optimal blocking condition. Another application would be for the central attacker to position themselves close to the setter, a strategy that would enable the use of the "pipe" attack in other areas of the court with lower defensive blocking power.9E1A-F9DD-3EB8 | Filipe Manuel ClementeN/
