title: Influence of bioceramic intracanal medication on the bond strength of bioceramic root canal sealer

description: Abstract To investigate the influence of the remaining volume of a new intracanal medication based on bioceramic compounds on the bond strength (BS) and formation of an adhesive interface between calcium silicate-based and epoxy resin-based root canal sealers. For this purpose, the specimens were distributed according to the intracanal medication (n = 26): Bio-C Temp (BCT) and Ultracal XS (UXS). The roots were scanned in microCT, and after 7 days, the medication was removed. Then a new scan was performed to evaluate the volume of medication remaining. Subsequently, 40 specimens were redistributed into 2 subgroups (n = 10) and filled according to the sealer used: AH Plus (AHP) and Bio-C Sealer (BCS), to assess the bond strength by using the push-out test, and the adhesive interface by confocal laser fluorescence microscopy (CLSM) and scanning electron microscopy (SEM). The t test showed a smaller remainder of BCT (1.77 ± 0.86) compared with UXS (10.47 ± 5.78), irrespective of the root third evaluated. The BS showed that teeth with BCT + BCS had higher bond strength values (3.70 ± 1.22) when compared to the other groups: BCT + AHP (2.15 ± 1.07), UXS + BCS (3.18 ± 1.09) and UXS + AHP (2.11 ± 1.02) (p&lt;0.001). The cervical third had higher BS when compared with the middle and apical thirds (p &lt; 0.001), and higher number of adhesive failures. The adhesive interface in SEM and CLSM images showed better adaptation for the association between BCT + BCS. Intracanal medication and silicate-based endodontic sealer appeared to interact chemically by forming a biomineralizing layer, allowing for an increase in the bond strength and forming an adhesive interface between the materials, with no or less gap formation.

title: A new and rare epigean asellid from western Mexico Caecidotea contrerasbalderasi sp. nov. (Isopoda: Asellidae) with a new suture pattern in pleopod IV for the Mexican epigean species

description: Abstract A new epigean asellid isopod, Caecidotea contrerasbalderasi sp. nov. is described from Nayarit, northwestern Mexico. This new species has morphological characters belonging to two different types of environments, both depigmentation and anophthalmia, indicators of organisms adapted to live in constant darkness as cavernicolous species. Despite showing characteristics of hypogean species, the new taxon does not show elongation of appendages, such as pereiopods, antennae or uropods. Its pleopod IV exopod lacks false sutures. This is a new pattern type “C”, and differs from that observed in types A and B. The description of this new species brings a new total of 101 species and three subspecies, for the genus Caecidotea in North America all morphologically poorly differentiated and with a restricted distribution.

title: Resistance to the use of the FM System by children and adolescents: fact or myth? An analysis of records of patients assisted in a hearing health center

description: ABSTRACT Purpose: to compare the use of the Frequency Modulation (FM) System by children and adolescents in a public hearing health center in the state of São Paulo. Methods: the analysis of medical records based on eligibility criteria. Data were collected from 340 participants born between 1998 and 2011, fitted with FM System, and who attended the follow-up appointment after fitting the device. Data were analyzed descriptively and inferentially. Results: hard-of-hearing children and adolescents of both genders from all over Brazil, attending elementary, middle or high school in public or private schools, participated. The data showed that 115 children and 155 adolescents effectively used the device, especially at school. The main difficulty for children was the lack of support from teachers; for adolescents, it was the feeling of embarrassment. Conclusion: some difficulties, especially on children, in adhering to the use of FM Systems were identified. Hence, to ensure the FM System's effective use, the importance of providing guidance and awareness of its benefits to patients, and their family members and teachers, during the fitting appointment and follow-up consultations, is emphasized.

title: Energy values and metabolizability coefficients of maize kernels with different specific gravities

description: Abstract The aim of this study was to examine the influence of the specific gravity of maize kernels on physicochemical traits, energy values, and metabolizability coefficients. Pearson’s correlations were evaluated between specific gravity (kg/m3) and crude protein (%); ether extract (%); crude fiber (%); gross energy (%); presence of fumonisins (ppb) and aflatoxins (ppb); and kernel quality (good, rotten, weevil-damaged, broken, and shriveled kernels, %). A metabolism trial was conducted with diets containing maize fractions of different specific gravities for male broilers from 14 to 21 days of age. Apparent metabolizable energy (AME), nitrogen-corrected AME (AMEn), and the metabolizability coefficients of dry matter (MCDM), crude protein (MCCP), ether extract (MCEE), calcium (MCCa), and phosphorus (MCP) were evaluated. The experiment consisted of five treatments (reference diet and diets with 40% replaced with maize at five specific gravities (740, 740, 760, or 800 kg/m3). Eight replications were used, totaling 400 broilers chickens. The Scott-Knott test was applied and regression equations were fitted to compare the treatments. Specific gravity had moderate correlations with good and broken kernels and low-magnitude correlations with chemical parameters. Increasing specific gravities caused AME and AMEn to increase linearly when analyzed on an as-is basis; and to respond quadratically when expressed on a dry-matter basis. The specific gravity of 780 kg/m3 provided the lowest MCDM, MCCP, MCCa, and MCP values, whereas the lowest MCEE, was found at the lowest density. It was not possible to determine the best nutritional composition or the best metabolizability coefficients.

title: ACUTE EFFECTS OF DIFFERENT INTERVALS BETWEEN REPEATED SPRINTS ON PERFORMANCE RESPONSES IN AMATEUR FUTSAL ATHLETES

description: ABSTRACT Objective: Verify the influence of different break times between sprints on the performance of amateur futsal athletes. Methods: 10 individuals, men, amateur futsal athletes (Age: 21.5 ± 1.6; Weight: 72.4 ± 6.88; Height: 1.72 ± 0.05; BMI: 24.3 ± 1.2; Fat%: 13.7 ± 3.3, VO2peak: 49.1 ± 10.5) participated in the study. Individuals were randomly selected to perform sessions with sprints (10 sets 20 m) with different pause times of 15 (S15), 30 (S30) and 60 (S60) seconds. For performance analysis, the speed (km / h) applied to each sprint was used and monitored by a device with a photocell (CEFISE Biotecnologia Esportiva®). Results: There was an interaction between speed and interval time (p = 0.000). For condition S15, a greater reduction in performance was observed (p ≤ 0.05), while for S30 and S60, no significant reduction in performance was observed (p &gt; 0.05). The data for the area under the curve showed a significant difference (p = 0.000), where the interval of 60 s (S60) was longer compared to the values of 30 (S30) (p = 0.000) and 15 s (S15) (p = 0.000). However, there were no significant differences between the 30 and 15 s data (p = 0.248). Conclusion: A shorter time (15 s) interval between repeated sprints can significantly affect performance compared to longer breaks (30 and 60 s), but all the conditions tested here can be positive for the improvement of performance, mainly in sports that demand fast and efficient motor actions such as futsal.

title: Tuber yield and quality of potato processing cultivars submitted to nitrogen rates

description: ABSTRACT Consumption of processed potatoes is increasing in Brazil. However, little information is available on the effect of nitrogen (N) rates on performance of potato cultivars developed in Brazil. The objective of this work was to evaluate yield and quality of tubers of potato processing cultivars, submitted to N rates at planting. Three field trials with eight treatments were conducted: two cultivars (Atlantic and BRSIPR Bel) and four N rates (0, 75, 150, and 225 kg/ha). Yield and quality of tubers were evaluated, as well as the post-frying absorbed oil content. Cultivar BRSIPR Bel showed higher total tuber yield (18% more) and commercial tuber yield (15% more) due to the production of higher number of tubers (29% more) compared to the cultivar Atlantic. On the other hand, Atlantic cultivar produced tubers with higher dry weight (22%) and lower oil absorption (38%). For both cultivars, the estimated N rate of 151 kg/ha resulted in the highest commercial tuber yield (diameter larger than 45 mm): 34.0 t/ha. For all studied variables there was no interaction between cultivar and N rate, concluding that the cultivars in this study (American and Brazilian origin) respond similarly to N rates.

title: Evaluation of enamel thickness of mandibular incisors

description: ABSTRACT Objective: To measure enamel thickness at the proximal surfaces of the mandibular incisors, using micro-computed tomography (micro-CT) scans. Material and Methods: Forty-one single-rooted mandibular incisors were selected and analyzed according to anatomical characteristics, to form three groups: Group 1 - central incisors (n = 18); Group 2 - right lateral incisors (n = 10); and Group 3 - left lateral incisors (n = 13). First, enamel thickness at the proximal contact areas of the mandibular incisors was measured. Second, the mesial and distal surfaces of the lateral incisors were compared. Finally, the relationship between the tooth width and the mean enamel thickness was determined. Each tooth was scanned with a micro-CT scanner, and the image was processed with SCANCO micro-CT onboard analysis software. Results: There were no statistically significant differences in mean enamel thickness between the mesial and distal surfaces for each lateral incisor, or between contralateral lateral incisors. In all surfaces analyzed, the upper zones had statistically significantly thinner enamel (0.52 ± 0.10 mm) when compared to the middle and lower zones (0.60 ± 0.08 mm and 0.59 ± 0.08 mm, respectively). There was no correlation (r =0.07) between enamel thickness of the mandibular incisor and the tooth width. Conclusions: The enamel thickness of the mandibular incisors is similar on the mesial and distal surfaces, with the thinnest layer located at the upper zone.
