title: Phytosanitary quality of Brachiaria brizantha ‘BRS Piatã’ seeds in function of climate conditions

description: ABSTRACT Infected seeds are one of the main pathogen transmission vehicles, and they are responsible for significant losses in production fields; phytosanitary defense depends on the inoculum and climatic factors. Thus, in this study, it was aimed to identify climatic variables of the regions that propitiate the production of Brachiaria brizantha ‘BRS Piatã’ seeds infected with phytopathogenic fungi. Temperature and rainfall data were obtained from 10 production fields, and phytosanitary quality of the seeds was evaluated with the filter paper method; the means were compared using the Kruskal–Wallis non-parametric analysis. Principal component analysis was performed to determine the relationship between the climatic variables and seed phytosanitary quality. Sites with maximum temperatures higher than 30 °C, mean values close to 25 °C, and rainfall less than 82 mm during harvest were favorable to the incidence of Fusarium spp. The incidence of Bipolaris sp. in the seeds of Piatã grass was favored by temperatures around 19 and 20 °C during the maturation phase. The highest incidence of Exserohilum sp. occurred at the sites in which the temperature during harvest was close to 20 °C and accumulated rainfall, between 167 and 181 mm.

title: Selection of maize top-crosses for different nitrogen levels through specific combining ability

description: ABSTRACT An alternative to increase yield without raising the production costs and minimizing the dependence of agricultural inputs is the development of maize genotypes presenting high nitrogen (N) use efficiency under low N level conditions. Thus, the objective of this study was to estimate the specific combining ability of maize top-crosses under high and low nitrogen (N) conditions and to select high-yielding hybrids for both conditions. The grain yield of 110 top-cross hybrids was evaluated in 2012 in two locations in the Brazilian Midwest. Partial diallel analysis was performed with the adjusted means of each of the individual top-cross analyses. Specific combining ability (SCA) of the hybrids and their interaction with N levels was estimated for each location. The mean grain yield of the 11 hybrids selected by the highest SCA estimates for high and low N was higher than the controls mean in approximately 330 and 241 kg∙ha-1. These results demonstrate that the selection for each environment was efficient and reveals the possibility of developing new hybrids for the Brazilian Cerrado region.

title: Distribution and fluctuations of backswimmers (Notonectidae) in a tropical shallow lake and predation on microcrustaceans

description: Abstract Notonectids are widely distributed in freshwaters and can prey on zooplankton in temperate lakes. However, its role in structuring the zooplankton community is unknown in tropical lakes. Thus, our objective was to study the notonectid Martarega uruguayensis in a Brazilian tropical shallow lake to evaluate its potential as a zooplankton predator. Its horizontal distribution was analized in the lake throughout one year in fortnightly samplings. Backswimmers were more abundant (mean density 162.9 ± 25.8 ind.m–2) in the cool-dry season, with a strong preference by the littoral zone (mean density 139.9 ± 17.5 ind.m–2). Laboratory experiments were undertaken with young and adult notonectid and the two most abundant cladocerans, Daphnia gessneri and Ceriodaphnia richardi, as prey. Predation by backswimmers in the laboratory showed that only juveniles fed on microcrustaceans (mean ingestion rate of 1.2 ± 0.2 Daphnia and 1.0 ± 0.2 Ceriodaphnia per predator per hour), without size selectivity. Adult insects probably have difficulties in detecting and manipulating small planktonic organisms. On the other hand, young instars might influence zooplankton community, especially in the littoral zone of the lake. This study does contribute to a better understanding of trophic interactions in tropical shallow lakes and is the first to investigate the predation of a notonectid on microcrustaceans from Lake Monte Alegre.

title: Clinical efficacy of resveratrol as an adjuvant with meloxican in the treatment of knee osteoarthritis patients: A double-blind, randomised, placebo-controlled trial

description: The present study aimed to evaluate the effect of the adjuvant use of resveratrol with meloxicam on the clinical scores of knee OA patients. This was a double-blind placebo-controlled randomised trial involving 100 patients with knee osteoarthritis performed at the Shar Teaching Hospital, Sulaimani General Hospital and Specialised Rheumatology Center, Sulaimani City from December 2016 to September 2017. The efficacy of the treatment was evaluated by measuring the changes from baseline in the KOOS score, WOMAC index, and VAS-100 score after 90 days of treatment. Resveratrol significantly improves the knee OA pain and associated symptoms compared with placebo, and both clinical scores were found to be eligible for following treatment outcomes. In conclusion, resveratrol, when used in combination with meloxicam, improves pain and symptom scores in patients with mild-to-moderate knee OA compared with placebo. The intervention with a dietary supplement may significantly impact the pain and overall quality of life in patients with knee OA.

title: Phytotherapy in reducing glycemic index and testicular oxidative stress resulting from induced diabetes: a review

description: Abstract Oxidative stress plays a main role in the development of diabetes complications. The impairment of gonadal antioxidant potential and endocrine disturbance in diabetic males causes testicular damage and failure in sperm production. Plants have been widely used to control diabetes due their hypoglycemic and antioxidant potential, contributing towards the recovery of testicular function. Current study comprises a review of the literature on the main medicinal plants used in the recovery of testicular oxidative damage in animals with experimental diabetes. Eighteen plant species in the nineteen studies selected from the search strategy were evaluated. Plant extracts were evaluated according to their effects on blood glucose and insulin levels, antioxidant enzymes and oxidant levels, lipid peroxidation, total protein, testosterone levels, gonadosomatic index, diameter of seminiferous tubules, seminiferous epithelium height and integrity, number of germ cells at stage VII and apoptosis in the seminiferous epithelium, sperm production, motility, viability and morphology. After the analysis of the studies, it was observed that plant species, used alone or in combination, may control testicular oxidative damage triggered by diabetes. The antioxidant potential varies among species, with some plants proving to have a better performance in the recovery of reproduction parameters than others.

title: The Casa Forte Square: a historic garden, a cultural heritage of Brazil

description: ABSTRACT Roberto Burle Marx created the Brazilian modern garden in Recife in the 1930s. He conceived the garden as an esthetic reintegration of the components of nature in which vegetation was the main element and, considering that, designed thirteen public gardens from 1935 to 1937, including Casa Forte Square, his first garden design. As the garden is perishable and renewable, according to The Florence Charter, due to all the physical and biological dynamics, the lack of conservation causes its degradation. Thus, this article presents the historiography of Casa Forte square to subsidize effective conservation actions.

title: Modeling and Experimental Validation of Two Adjacent Portal Frame Structures Subjected to Vibro-impact

description: Abstract In many engineering applications, there are systems that exhibit a series of collisions in a certain amount of time, for example the impact of floating ice in ships and the rubbing between stationary and rotary parts in turbomachinery. In many of these situations, it is of vital importance to know how the impacts affect the overall system behavior for the correct functioning or the prediction of faults in the system. This can be done by proposing models that can represent the system when it is subjected to sudden impacts in its oscillation movement. However, due to the nonlinear and non-smooth characteristic of the impact phenomenon, the implementation of impacts in mechanical systems may be a challenging task. In this manner, this paper aims in proposing a vibro-impact model of two adjacent portal frame structures, being one of them driven by an unbalanced DC motor positioned on top of it. The portal frames were modeled as continuous beams by means of the Euler-Bernoulli beam theory. In order to model the impact between the structures, three different models were considered: using the Hertz theory of elastic bodies to model the contact force using a nonlinear damping; using a spring and a damper in parallel, viscoelastic or spring-dashpot system, to model the force; and considering the impact to be instantaneous and using the coefficient of restitution to adjust the velocity after the contact. To validate the impact models, an experimental procedure was performed and the measurements compared with the simulations.

title: AEROBIC AND RESISTANCE EXERCISE IN PATIENTS WITH RESISTANT HYPERTENSION

description: ABSTRACT Introduction: Physical training is recommended by current guidelines as a preventive measure and as a tool to supplement pharmacological therapy in the treatment of hypertension and its pathological manifestations. However, there is considerable uncertainty regarding the best training prescription for blood pressure control in patients with resistant hypertension. Objective: To evaluate the effect, over twelve weeks, of an aerobic and resistance exercise program on blood pressure, anthropometric and biochemical parameters of patients with resistant hypertension. Methods: Eleven patients with resistant hypertension were randomly divided into two groups: resistance training and aerobic training. Blood pressure was recorded by 24-hour outpatient monitoring before and after 12-week training. The Student t-test was used to compare resistance and aerobic exercise groups, while the paired t and Wilcoxon tests were used to analyze pre- and post-exercise data. The level of significance was 0.05. Results: In the group that underwent aerobic training, mean systolic, diastolic and total blood pressure readings were significantly lower over the 24 hours analyzed, dropping by 14 mmHg, 7 mmHg and 10 mmHg, respectively, and in the waking period. The resistance training group showed no significant change in blood pressure, despite the significant improvement in HDL levels. Conclusion: Twelve weeks of aerobic exercises resulted in significantly lowered blood pressure in individuals with resistant hypertension, while resistance exercises were more effective in increasing HDL. Level of evidence II, Therapeutic study.

title: South Brazilian farmers’ perceptions concerning sheep tail docking

description: ABSTRACT: The objective of this study was to better understand farmers’ perceptions regarding sheep welfare and procedures concerning the tail docking of sheep in the state of Parana, Southern Brazil. The study was carried out via telephone interviews or personally with 146 sheep farmers. Twenty-eight farmers (19.2%) did not tail dock; the main reasons given were because they raised short-hair sheep breeds. One hundred and eighteen farmers docked their sheep tails (80.8%). The main reasons given were hygiene (61.0%), facilitated mating (42.4%), breed standards (29.7%), and esthetics (26.3%). Rubber ring was the main method used for tail docking. Although farmers in Parana recognized that sheep are sentient animals and that tail docking causes pain, anesthesia was used by only six (5.1%) farmers during the procedure of tail docking. Our results showed that farmers’ opinions on sheep tail docking are divergent. Farmers who perform tail docking must be encouraged to use anesthesia and analgesia, and to ponder on the real need for the practice. This statement seems especially relevant considering the fact that some farmers reported the viability of maintaining wool sheep with undocked tails and that they recognized the suffering involved in this procedure.

title: The construction of civic space: monuments and rituals of memory in republican Natal (1902-1922)

description: ABSTRACT This article analyzes the formation process of civic space in Natal between 1902 and 1922. We seek to comprehend the central role of local historians and of Instituto Histórico e Geográfico do Rio Grande do Norte (Historical and Geographical Institute of Rio Grande do Norte) in the construction of a public republican memory through the assemblage of artifacts, the attribution of new meanings to public sites and the practice of civic rituals. This research aims to understand how the practice of naming and renaming streets and public parks, creating squares, the carving and installation of statues, busts, tombstones, hermas and paintings, the identification of “historical sites” and the construction of places built to house collected relics and “historical objects”, as well as for the historical celebration of noteworthy characters and events that were important when constructing a collective identity in which the historical consciousness should have a critical role.
