title: Protists and other organisms on a minute snail periostracum

description: Abstract Since the foundation of the Malacological Center in 1980, Universidad Centro Americana (UCA), Managua-Nicaragua, has been monitoring and collecting the marine, terrestrial, fluvial and lake mollusk population of the country. Many specimens have been photographed by Scanning Electronic Microscope (SEM), and in one of these, observation of the hairy periostracum reveals a seemingly thriving population of minute protists in possible symbiosis with their host. Adequate magnification and comparison with previous studies allowed the determination of these hosts as diatoms, testaceous amoebae, yeast, phacus, spores and other undetermined organisms which occur in tropical forests on rocks, trees and leaves. Here illustrated are diatoms and other organisms detected for the first time on the periostracum of a tropical rainforest mollusk.

title: Do Irrigation Solutions Influence the Bond Interface Between Glass Fiber Posts and Dentin?

description: Abstract The aim of this study was to evaluate the push-out bond strength and interface permeability of glass-fiber posts in different regions of post space (cervical, middle, and apical) submitted to different irrigation solutions. Ninety single-rooted human teeth were submitted to endodontic treatment and divided into five groups, according to irrigation solutions: distilled water, 5.25% NaOCl, 25% polyacrylic acid, 2% chlorhexidine, and 23 ppm Ag NP dispersion. Each group was divided in 3 subgroups (n=6) according to cementation: SBU: Adper Scotchbond Universal + RelyX ARC; U200: RelyX U200; MCE: MaxCem Elite. Bond strength and sealing ability were measured in different areas of post space. The data was subjected to ANOVA and Fisher’s test (a=0,05). The silver nanoparticle solution showed highest bond strength values and lowest interface permeability in all thirds analyzed for SBU group. In the U200 group, the highest bond strength values were found for sodium hypochlorite solution, with significant difference between this solution and polyacrylic acid. A decrease in bond strength values in cervical to apical direction was found for MCE group and the same behavior were found for others groups. Regarding interface permeability, use of silver nanoparticle solution resulted in lower values in cervical and apical thirds. There was a decrease in bond strength in cervical to apical direction. Different irrigation solutions and intraradicular depth influenced the bond strength and interface permeability of adhesive material to dentin substrate. Silver nanoparticle solution can effectively be used as an irrigation agent in post space prior to fiber post cementation process.

title: Brittleness index and its relationship with materials mechanical properties: Influence on the machinability of CAD/CAM materials

description: Abstract: The aim of this study is to evaluate the machinability of four CAD/CAM materials (n = 13) assessed by brittleness index, Vickers hardness, and fracture toughness and interaction among such mechanical properties. The materials selected in this in vitro study are Feldspathic ceramic [FC], Lithium-disilicate glass ceramic [LD], leucite-reinforced glass ceramic [LR], and nanofilled resin material [RN]. Slices were made from the blocks following original dimensions 14 × 12 × 3 mm (L × W × H), using a precision slow-speed saw device and then surfaces were regularized through a polishing device. Brittleness index and fracture toughness were calculated by the use of specific equations for each one of the properties. The Vickers hardness was calculated automated software in the microhardness device. One-way Anova and Pearson's correlation were applied to data evaluation. LD obtained the highest values for brittleness index and was not significantly different from FC. LR presented statistically significant difference compared with RN, which had the lowest mean. Vickers hardness showed LD with the highest average, and no statistical difference was found between FC and LR. RN presented the lowest average. Fracture toughness showed FC and LR not statistically different from each other, likewise LD and RN. The brittleness index, considered also as the machinability of a material, showed within this study as positively dependent on Vickers hardness, which leads to conclusion that hardness of ceramics is related to its milling capacity. In addition, fracture toughness of pre-sintered ceramics is compared to polymer-based materials.

title: Diet selenium improves the antioxidant defense system of juveniles Nile tilapia ( Oreochromis niloticus L.)

description: Abstract From the advancement of tilapia production in recent years, diets are sought that allow the maximum growth, improving health and fish quality. In this study growth, biochemical, hematological and oxidative parameters were evaluated of tilapia fed with increasing selenium levels: 0.53, 0.86, 1.04 and 1.22 mg kg-1. It was used 400 juveniles (initial weight = 36.51 ± 10.88 g), fed for six weeks. There was no effect of selenium on fish growth, biochemical and hematological parameters. In the oxidative parameters, there was an increase in non-protein thiols and a decrease in malondialdehyde levels, evidencing antioxidant effects of selenium. The diet selenium levels above 0.86 mg kg-1 improved the antioxidant system and does not affect to biochemical, hematological and growth parameters of tilapia juveniles.

title: Black Drums, White Ears: Colonialism and the Homogenization of Social and Cultural Practices in Southern Mozambique (1890-1940)

description: ABSTRACT In this article, I analyse how practices referred to generically in the historical documentation as ‘batuque’ (drums) underwent a process of homogenization and scrutinization by diverse Portuguese colonial agents. On one hand, the colonial agents insisted on unifying everything they saw as dance and music under the generic category of ‘batuque.’ On the other hand, the need for a better understanding of the subordinate Africans ended up producing colonial responses that shifted between a dissection of the term in search of a more accurate apprehension of what was being observed and an incorporation of these practices into the colonial enterprise. This process was conceived by the colonial agents as a way of appropriating the dances, songs and music made by the natives of southern Mozambique into the ultramarine Portuguese nationalist discourse.

title: Achilles tendon of wistar rats treated with laser therapy and eccentric exercise

description: ABSTRACT Introduction: Both laser therapy and eccentric exercises are used in tendon injuries. However, the association of these physiotherapeutic modalities is yet little investigated. Objective: To evaluate the effect of low-level laser therapy associated to eccentric exercise (downhill walking) on Achilles tendinopathy of Wistar rats. Method: Eighteen Achilles tendon from 15 adult male Wistar rats were used. Tendons were distributed in six groups (laser, eccentric exercise, laser and eccentric exercise, rest, contralateral tendon, and healthy tendon). Unilateral tendinopathy was surgically induced by transversal compression followed by scarification of tendon fibers. The treatments laser therapy (904 nm, 3J/cm²) and/or eccentric exercise (downhill walking; 12 m/min; 50 min/day; 15o inclination treadmill) began 24 hours after surgery and remained for 20 days. Clinical and biomechanical analyzes were conducted. Achilles tendon was macroscopically evaluated and the transversal diameter measured. Euthanasia was performed 21 days after lesion induction. Tendons of both limbs were collected and frozen at -20°C until biomechanical analysis, on which the characteristic of maximum load (N), stress at ultimate (MPa) and maximum extension (mm) were analyzed. Results: Swelling was observed within 72 hours postoperative. No fibrous adhesions were observed nor increase in transversal diameter of tendons. Animals with the exercised tendons, but not treated with laser therapy, presented lower (p=0.0000) locomotor capacity. No difference occurred be-tween groups for the biomechanical characteristics maximum load (p=0.4379), stress at ultimate (p=0.4605) and maximum extension (p=0.3820) evaluated, even considering healthy and contralateral tendons. Conclusion: The concomitant use of low-level laser and the eccentric exercise of downhill walking, starting 24 hours after surgically induced tendinopathy, do not result in a tendon with the same biomechanical resistance or elasticity as a healthy tendon. On the other hand, it also does not influence negatively the structure and function of the Achilles tendon.

title: Assessment of body composition and dietary intake of adolescent swimmers

description: ABSTRACT Introduction: Body composition and nutritional habits of swimmers have a direct influence on their sports perfor-mance. Objective: To assess body composition and dietary intake of adolescent swimmers. Method: Cross-sectional study with 15 adolescent swimmers of both genders from a club in the city of São Paulo, Brazil. An identification questionnaire was applied, registering information on weight, height, body circumferences and skinfolds. For the assessment of dietary intake, a 24-hour recall was applied. Results: Most of the athletes presented appropriate body fat percentage. All swimmers ingested dietary supplements. Protein consumption was high and carbohydrate, low. The highest prevalence of inadequate intakes of micronutrients were vitamin B9, iodine and calcium. Conclusion: The results suggest the need for nutritional intervention in this group of athletes.

title: Morphological and Metabolic Changes in Soybean Plants Cultivated in Irrigated Rice Rotation and as Affected by Imazapyr and Imazapic Herbicides Carryover

description: ABSTRACT: The appearance of soybean cultivars that are tolerant to herbicides from the imidazolinone group enables irrigated rice rotation conducted on Clearfield® system. The objective of this work was to evaluate the morphological and metabolic changes of soybean cultivars containing Cultivance® (CV), which is tolerant to imidazolinone, sulphonylurea toletant (STS) and Roundup Ready® (RR), which is tolerant to glyphosate as affected by carryover of increasing doses of imazapyr and imazapic herbicides mixture, applied in the management of irrigated rice crop. Thus, experiments were conducted on the field and in greenhouse, evaluating phytotoxicity, height, leaf area, shoot dry matter, as well as variables related to the secondary metabolism of plants like chlorophyll, carotenoids, hydrogen peroxide, lipid peroxidation and electrolytes leakage. Soybean cultivars RR and STS are susceptibles to the carryover of imazapyr and imazapic mixture applied in the management of irrigated rice crop, whereas the CV cultivar is resistant. The rise in the herbicide carryover dose increases the reactive oxygen species (ROS) production in soybean plants. The RR cultivar, in general, shows higher ROS production compared to the other soybean cultivars.

title: Benefits of inserting the physical therapist on the profile of low-risk premature infants admitted to an intensive care unit

description: ABSTRACT This study aims to describe the benefits of inserting the physical therapist on the profile of low-risk premature infants in neonatal intensive care units. This is a retrospective control study, with consultation to the medical records of premature infants admitted in 2006/2007 without physical therapy (PREP) and in 2009/2010 with physical therapy for up to 8h/day (POSTP). 61 preterm infants in the PREP period and 93 in the POSTP were included, born with ≥1000g, SNAP-PE II &lt;40, with a duration of ventilatory support ≥24h. Maternal and neonatal profiles, duration of hospitalization, invasive and non-invasive mechanical ventilation and oxygen therapy were verified. Descriptive analysis, the Mann Whitney test, t-test, Chi-squared and Fisher’s test were performed, considering p≤0.05. There was a significant difference between gestational ages [PREP: 230.5 (±16.5)/POSTP: 226 (±15); p = 0.05], frequency of sepsis [PREP: 6 (10%) / POSTP: 30 (32%); p &lt; 0.01], respiratory distress syndrome [PREP: 11 (18%)/POSTP: 43 (46%); p &lt; 0.01], need for resuscitation in the delivery room [PREP: 10 (16%) / POSTP: 32 (34%); p = 0.02], need for orotracheal intubation [PREP: 8 (13%)/POSTP: 26 (28%); invasive ventilation (PREP: 0.4±1.3 days/POSTP: 1.3±3.3 days, p = 0.04), continuous positive airway pressure (PREP: 1.5±1.0 days/POSTP: 2.7±3.8 days, p = 0.04). The presence of the physical therapist generated benefits, contributing to the maintenance of the length of hospitalization and oxygen therapy in face of a profile of more immature newborns and with more complications in the period after physical therapy was inserted.

title: Renal arteriovenous fistula after renal biopsy: a case report and literature review

description: Abstract Acquired renal arteriovenous fistulas (AVF) are rare conditions in which an anomalous connection arises between the arterial and venous systems. Renal AVFs can be classified into three main groups: idiopathic, congenital, and acquired, the last of which are the most common. Incidence has been increasing, due to the growing number of renal biopsies. Although the renal biopsy procedure is relatively safe nowadays, one possible complication is formation of an AVF in the renal vascular territory. Treatment of renal AVF is widely discussed in the literature and a variety of treatment methods can be employed. We report a case of arteriovenous fistula after renal biopsy that was successfully treated with endovascular coil embolization.
