title: Fructan dynamics in the underground organs of Chresta exsucca (Asteraceae), a dry season flowering species

description: ABSTRACT Climatic seasonality has an influence on the phenology of native Cerrado plants. Herbs and subshrubs tend to flower in the rainy season, although some species of these habits flower in the dry season. Reserve carbohydrates, stored in the underground organs, are used to support phases of high energy-demand, but also may protect plants from damage during periods of environmental limitation. In this study we evaluated variation in fructan levels in the underground organs of field-grown plants of Chresta exsucca among different phenological phases. Chresta exsucca flowers in the dry season and possesses a diffuse underground system, which stores inulin-type fructans. Resprouting was continual during the sampling period. Oligosaccharide content was always higher than polysaccharide content, except during senescence, the only phase with an oligosaccharide: polysaccharide ratio &lt; 1. Fructan accumulation occurred during vegetative growth until flowering. Fructan mobilization was prominent during resprouting until the beginning of vegetative growth. Fructans stored in the underground organs of C. exsucca serve to fulfill the energetic demands of development and maintenance of this complex structure. In this way, fructans are essential to the persistence of this species in the environment of the Cerrado by ensuring reproduction in harsh conditions, such as drought.

title: High prevalence of enteroparasites in children from Ribeirão Preto, São Paulo, Brazil

description: ABSTRACT Objective: To determine the prevalence of intestinal parasites and possible associated factors. Method: Cross-sectional epidemiological study of 962 children (3-12-years) from an area within the scope of a basic health unit in Ribeirão Preto, São Paulo, Brazil. Data were collected by home interviews and three-sample stool analysis and evaluated with the chi-square and Fisher's exact tests (p&lt;0.05). Results: The prevalence of intestinal parasites was significantly high (57.5%). Giardia lamblia was the most prevalent (50.8%), followed by Ascaris lumbricoides (17.8%), Entamoeba histolytica, Hymenolepis nana, Entamoeba coli and Enterobius vermiculares (5.6-7.3%) and other parasites of lower prevalence, such as Schistosoma japonicum (1%) and Schistosoma mansoni (0.5%). No statistically significant associations were detected between prevalence and the risk factors analyzed. Conclusion: Since the area presents good conditions of environmental sanitation, health education programs should be implemented that emphasize hygiene procedures for the hands and for food and water to be consumed by the population.

title: Is the herb-shrub composition of veredas (Brazilian palm swamps) distinguishable?

description: ABSTRACT Vereda (Brazilian palm swamp) is a poorly known savannic phytophysiognomy that occurs on moist soils with high herb-shrub floristic richness. This study aimed to document the herb-shrub species of veredas of the Estação Ecológica Serra Geral do Tocantins - EESGTO, and compare this flora with other veredas in Brazil. Furthermore, we assessed the similarity of the herb-shrub ﬂora of the studied veredas with that of inventories of other savannas and grasslands in order to evaluate whether veredas possess an exclusive flora. Ordination analysis was performed to understand the floristic relationship among these areas. We recorded 213 species, 105 genera and 49 families at EESGTO, including five new floral records for the Cerrado and 78 for the state of Tocantins. The floristic similarity among veredas at EESGTO and the other sites was low. For all sites, a total of 1,324 species were recorded, of which 342 were unique to veredas and 187 unique to moist grasslands (campos limpos úmidos). After reviewing databases, 14.3 % of these species remained exclusive to veredas and moist grasslands. The ordination analysis indicated a gradient in floristic composition from wet to dry phytophysiognomies. In conclusion, we recognize a flora that distinguishes veredas from other Cerrado phytophysiognomies.

title: The effects of local ischemic preconditioning and topical hypothermia in renal ischemia/reperfusion injury in rats

description: Abstract Purpose: Topical hypothermia and local ischemic preconditioning have been shown to reduce renal ischemia-reperfusion (I/R) injury individually. We examined whether combination of both strategies lessens renal I/R injury. Methods: Post right nephrectomy, 40 male Wistar rats were randomly assigned to five experimental protocols performed in the left kidney: topical hypothermia without ischemia (TH), warm ischemia (IR), ischemic preconditioning followed by warm ischemia (IPC+IR), cold ischemia (TH+IR), and ischemic preconditioning followed by cold ischemia (IPC+TH+IR). Eight randomly assigned right kidneys constituted the control group. After 240 min of reperfusion, the left kidney was retrieved to evaluate histological changes, lipid peroxidation and antioxidant enzymes activity. Serum was collected to evaluate urea and creatinine. Results: IPC+TH+IR group revealed no difference to any other group subjected to ischemia in relation to histological changes, lipid peroxidation and antioxidant enzymes activity. Creatinine was lower in IPC+TH+IR group compared with IPC+IR, but showed no difference compared to TH+IR group. Conclusions: Combination of local ischemic preconditioning (IPC) and topical hypothermia conferred no protection in renal I/R injury. Moreover, local IPC solely followed by warm ischemia impaired renal function more than warm ischemia alone.

title: Erdosteine ameliorates the harmful effects of ischemia-reperfusion injury on the liver of rats

description: Abstract Purpose: To investigate the potential protective effects of erdosteine against the harmful effects of ischemia-reperfusion injury on the liver in an experimental rat model. Methods: Forty rats were divided into 4 groups. In the sham group, only the hepatic pedicle was mobilized. No other manipulation or treatment was performed. In the other groups, ischemia was achieved by clamping the hepatic pedicle for 60 min. After that, 90 min reperfusion was provided. In the control group, no treatment was given. In the perioperative treatment group, 100 mg/kg erdosteine was administered 2 hours before ischemia induction. In the preoperative treatment group, 100 mg/kg/day erdosteine was administered daily for ten days before the operation. At the end of the procedures, blood and liver samples were obtained for biochemical and histopathological assessment. Results: Treatment with erdosteine ameliorated the histopathological abnormalities when compared with the control group. Furthermore, this treatment significantly decreased the serum liver function test values. It was also found that erdosteine ameliorated the oxidative stress parameters in both the perioperative and preoperative treatment groups. Conclusion: The current study is the first to have shown the favorable effects of erdosteine on the harmful effects of experimental hepatic ischemia-reperfusion injury.

title: Corrosion Mechanism Suggested Based on Electrochemical Analysis and SVET for Uncoated Tinplate and Post Coated With a Hybrid Film

description: The tinplate, used in the packaging sector and formed from a metal substrate, comprises a steel base which has undergone a surface treatment to produce a thin layer of FeSn2, a tin layer and an oxide tin layer. Currently, packaging using surface treatment is based on the use of chromates because these metals provide an excellent corrosion resistance. Nontoxic alternatives to pre-treatments have been developed in recent years to replace the chromate process. The aim of this work is to analyze the performance of a new hybrid organic-inorganic film obtained from sol-gel consisting of the alkoxide precursors 3-(Trimethoxysilylpropyl)methacrylate (TMSM) and tetraethoxysilane (TEOS) with the addition of cerium nitrate with the scanning vibrating electrode technique (SVET), and electrochemical and morphological characterizations. Moreover, the evolution of the corrosion of the substrate was evaluated to propose a mechanism of corrosion. The results showed a galvanic coupling between the Sn/SnO2 coat (cathode) and the defects exposed at the ferrous base (anode). The organic-inorganic hybrid film containing a cathodic corrosion inhibitor was able to retard the corrosion of the tinplate.
