title: Effect of enzymatic complex in the diet of pirarucu, Arapaima gigas juveniles

description: ABSTRACT The pirarucu, Arapaima gigas is a native, carnivorous fish species from the Amazon basin. As carnivorous fish have low amylase activity, exogenous enzymes can improve the digestibility of carbohydrates in aquaculture feeds. We evaluated the digestibility of increasing levels of an enzymatic complex in diets of pirarucu juveniles (65.2 ± 0.4 g). The experimental design was randomized with four treatments [diets containing 0.25, 0.50, 0.75, and 1 g kg-1 on-top inclusion of an enzyme complex (Allzyme® SSF®, USA), and a control, with three replications at a density of 5 fish per unit, and a 30-day duration. We quantified apparent digestibility of dry matter, crude protein, and crude energy through nutrient and chromium oxide content in diets and feces. Enzymatic activity, hepatic glycogen and total protein were determined in liver and anterior intestine samples. The diet with 1 g kg-1 of enzyme-complex resulted in an increase in apparent digestibility of crude protein, gross energy, and dry matter, hepatic glycogen, total proteins in liver and in intestine, showing the efficiency of the enzyme complex in pirarucu feeding. A higher accumulation of dry matter, crude energy, and ethereal extract in the carcass indicated weight increase in the fish treated with enzymatic complex. A decrease in the endogenous enzymatic activity (protease, lipase and amylase) suggested an improved efficacy of the digestive process. Our results indicate that the inclusion of 1 g kg-1 enzyme complex in the diet of juvenile pirarucu can be recommended to achieve greater digestibility of nutrients and improvement in productive performance.

title: Dendrometric characterization of Cupressus lusitanica mill. planted under Pinus taeda L. shelter in southern Brazil

description: ABSTRACT Background: We analyzed if C. lusitanica can be planted in a shelterwood system with P. taeda as the shelter stratum. The study was conducted in a 13-yr-old C. lusitanica stand under P. taeda canopy in Southern Brazil. Samples of these trees were measured in terms of diameter at breast height (DBH), total height, individual volume, and crown projection area. The species´ growing space efficiency (GSE) was also analyzed. A 10-meters distance criterion from P. taeda trees was applied to check their influence on C. lusitanica growth behavior through correlation. Results: The 36-yr-old P. taeda trees showed expressive means in the dendrometric variables, compatible with its age (mean DBH of 58 cm, total height 30 m, individual volume of 3.7 m³, and crown projection area of 128 m²). There was a statistically significant effect (p&gt;0.05) of P. taeda cover on C. lusitanica diameter (mean of ~13 cm). Although not significant, an effect of P. taeda canopy was also observed on C. lusitanica height. The two species summed a basal area of 36.5 m² ha-1 and a crown projection area of 34,209.2 m² ha-1. A tendency of increasing GSE with increasing diameter was observed for both species. Conclusion: These results show that a shelterwood with C. lusitanica under P. taeda is possible, but further investigations with longer production cycles and with silvicultural treatments (i.e. thinnings and shelter removal) should be conducted for a better understanding of shelterwood systems with these species in southern Brazil in terms of growth performance and soil use sustainability.

title: Serum Thiol Levels and Thiol/Disulfide Homeostasis in Patients with Rheumatic Mitral Valve Disease and Healthy Subjects

description: Abstract Background Rheumatic mitral valve disease (RMVD) is the most common presentation of rheumatic heart disease (RHD). Inflammation and fibrosis processes also play significant roles in its pathogenesis. Recent studies showed that thiols and thiol-disulfide are promising novel oxidative stress markers. Objectives The present study aimed to evaluate differences in the serum thiol and thiol-disulfide levels in patients with RMVD and the control group. Methods Ninety-two patients with RMVD were enrolled in the study. Fifty-four healthy subjects, age, and gender-matched with the study group, were also included in the study as a control group. This study investigated thiol levels in patients with RMVD and the control group. P-values lower than 0.05 were considered statistically significant. Results The patients with RMVD presented higher systolic pulmonary artery pressure (SPAP) and left atrial (LA) diameter levels than the control group. Native thiol (407±83 μmol/L vs. 297±65 μmol/L, p&lt;0.001) and total thiol (442±82 μmol/L vs. 329±65 μmol/L, p&lt;0.001) levels were higher in the control group. Disulfide (16.7±4.9 μmol/L vs. 14.8±3.7 μmol/L, p=0.011) levels were higher in the group of patients with RMVD. A positive correlation was found between disulfide/native and disulfide/total thiols ratio with SPAP, LA diameter, and MS severity. Disulfide/total thiols ratio was significantly higher in patients with severe MS than with mild to moderate MS patients. Conclusions To the best of our knowledge, this is the only study of its kind that has evaluated thiol/disulfide homeostasis as a novel predictor, which was more closely related to RMVD and the severity of MS.

title: Evaluation of Heat Stress Through Temperature and Pupillary Dilatation of the Guinea Fowl (Numida Meleagris) in a Controlled Environment

description: ABSTRACT The commercial exploitation of guinea fowl (Numidia meleagris) is a viable alternative for small rural properties in arid and semi-arid regions, as they are rustic birds and capable of withstanding the climatic adversities of these regions. The objective of this study was to evaluate the pupillary temperature, smaller pupillary diameter, larger pupillary diameter and pupil area of guinea fowl housed in a controlled environment, under two air temperatures: 26 ºC (thermal comfort zone) and 32 ºC (above the thermal comfort zone). The birds were distributed in a completely randomized design, with two treatments (air temperatures) and four replications (experimental box), with twelve birds each. The increase in air temperature resulted in a significant average increase (P &lt; 0.05) of 6.0, 17.9, 18.6 and 38.4%, respectively, in pupillary temperature, smaller pupillary diameter, larger pupillary diameter and pupillary area of birds, being these measurements accurate in evaluation of thermal stress in homeothermic animals.

title: Content of Stereotypes and Racial Prejudice: Effects of Cordiality and Competence

description: Abstract Using the Stereotype Content Model (SCT), we analyzed in two studies the relationship between the dimensions of warmth and competence of stereotypes with the racial prejudice expressions. In the first study, 169 undergraduates participated (M age=21.7 years, 47% brown skin). We found implicit prejudice, greater attribution of competence to whites than to blacks and a relationship between modern racism and attribution of competence to whites. In the second study, 143 undergraduates took part (M age=25.4, 64.9% brown skin). We found that blacks described as incompetent-friendly received greater competence stereotyping than whites incompetent-cold. We concluded that: 1) the dimension of warmth did not apply to blacks and 2) there is a relationship between SCT and racial prejudice expressions.

title: Restoration potential of eight tree species from a seasonally dry tropical forest in southeast Piauí, Brazil

description: ABSTRACT Background: The conservation and restoration of forest landscapes is an important aspect of sustainable development. In semi-arid regions these practices are difficulted by the harsh climate of these environments, with low precipitation values and prolonged dry seasons. The objective of this study is to identify tree species from the south of the Brazilian state of Piauí that have potential to be used in forest restoration programs. Results: Data from forest inventory and tree characteristics were used to select eight tree species using target species definition, focusing on species with desirable wood properties, abundance in the study region, favorable dendrometric variables, seed availability, ease of seed germination and seedling growth in nursery and field conditions, among others. These species were then evaluated as candidates for restoration using a framework species approach focusing on the following attributes: (i) 70% or higher seedling survival in the field; (ii) seedling height of 45 cm or taller after the first growing season in the field and (iii) 70% or greater nursery seedling survival. Conclusion: The species Combretum glaucocarpum, Cenostigma macrophyllum, and Pityrocarpa moniliformis are suitable to be employed in forest restoration programs in the southern region of Piauí, Brazil. Further studies must be carried out to assess the behavior of these and other potential tree species in long term field conditions and under varying silvicultural regimes, a key aspect for forest restoration.

title: Late follow-up of peripheral neural decompression in leprosy: functional and clinical outcomes

description: ABSTRACT Background: Peripheral neural surgical decompression (PNSD) is used as a complementary therapy to the clinical treatment of neuritis to preserve neural function. Objective: To evaluate the long-term (≥ 1 year) clinical and functional results for PNSD in leprosy neuritis. Methods: This cross-sectional study included leprosy patients who were in late postoperative period (LPO) of surgical decompression of ulnar, median, tibial, and fibular nerves. Socioeconomic, epidemiological, and clinical data were collected. The following instruments were used in this evaluation: visual analogue pain scale (VAS), Douleur Neuropathique en 4 Questions (DN4), SALSA scale, and simplified neurological assessment protocol. The preoperative (PrO) and 180-day postoperative (PO180) results were compared. Results: We evaluated 246 nerves from 90 patients: 56.6% were on multidrug therapy (MDT) and 43.3% discharged from MDT. Motor scores and pain intensity showed statistically significant improvement (p&lt;0.01). There was an increase in sensory scores only for bilateral ulnar nerves (p&lt;0.05). Of the operated cases, 26.0% of patients were referred for surgery of ulnar neuritis and 23.6% of tibial neuritis. Neuropathic pain was reported in 41% of cases. Daily dose of prednisone reduced from 39.6 mg (±3.0) in PrO, 16.3 mg (±5.2) in PO180, to 1.7 mg (±0.8) in LPO. The SALSA scale results showed mild activity limitation in 51% and moderate in 34% of patients. Eighty percent of individuals reported that the results reached their expectations. Conclusions: PNSD in leprosy was effective in the long term to decrease the prevalence and intensity of pain, improve motor function, and reduce the dose of corticosteroids, which is reflected in the patients’ satisfaction.

title: Quality of Handroanthus serratifolius (Vahl) S. O. Grose seeds evaluated by the electrical conductivity test

description: ABSTRACT - The electrical conductivity test (EC) used to evaluate seed vigor is directly related to the integrity of cell membranes, but its use in forest species is still restricted. Thus, the objective of this study is to analyze the efficiency of the EC test to evaluate physiological parameters regarding seed quality and the genetic variability among Handroanthus serratifolius mother trees. Seeds from 15 mother trees were evaluated for germination (G%) and germination speed index (GSI). In the EC test, the seeds were imbibed in two water volumes (75 and 100 mL) at 20 and 25 °C, and the electrical conductivity was measured after five imbibition periods (24, 48, 72, 96, and 120 h). The germination test data were submitted to a randomized block design (RBD) analysis of variance and means were compared by the Scott-Knott test. The EC test was conducted as an RBD in a split-split plot scheme, with interaction unfolding by polynomial regression analysis. The mother trees were divided into four groups regarding G% and SGI. The EC test separated the mother trees into a larger number of groups, regardless of temperature, volume, and imbibition period. In conclusion, the EC test consisting of imbibition 25 seeds in 75 mL of deionized water at 20 °C for 48 h is suitable for evaluating the physiological quality of seeds and the variability among mother trees of Handroanthus serratifolius (Vahl) S. O. Grose.
