Authors: Vershinina E. O. , Repin A. N.
Published: December 2018

Aim.To evaluate the frequency and identify predictors of long­term fatal cardiovascular events (CVE) after planned percutaneous coronary interventions (PCI).

Material and methods. We conducted a retrospective study that included 150 patients who underwent planned endovascular intervention on the coronary arteries. Outcomes of interventions were assessed 6 years after the PCI, by analyzing medical records and telephone interviews. The primary endpoint of the study was cardiovascular­related death.

Results.Fatal CVE were recorded in 10,6% of patients. A statistically significant relationship was found between the development of fatal CVE in the long­term period after planned PCI and the presence of initial chronic obstructive pulmonary disease in patients (OR=12,3; CI (3,6­41,5); р<0,001), atrial fibrillation (OR=5,1; CI (1,6­16,3); p=0,003), diabetes mellitus (OR=3,2; CI (1,1­9,8); p=0,032), acute cerebrovascular accident (OR=8,6; CI (2,0­36,4); p=0,001); any clinical complications of interventions (OR=3,1; CI (1,1­9,0); p=0,028), taking of antiarrhythmic drugs (OR=5,9; CI (1,3­27,4); p=0,012), statins taking at the time of PCI (OR=0,3; CI (0,1­0,8); p=0,013). According to the results of the ROC­analysis, the most significant predictor of fatal CVE in the long­term period was erythrocyte sedimentation rate more than 14,5 mm/h (AUC=0,677; CI (0,507­0,835); p=0,027). According to 6­year observation, Kaplan­Meier curves showed a significant effect of multifocal atherosclerosis, acute periprocedural kidney injury and heart rhythm disorders recorded during PCI, on the incidence of long­term fatal CVE.

Conclusion.A statistically significant relationship between the development of fatal CVE in the long­term period after planned PCI and the presence of initial comorbid pathology in patients (chronic obstructive pulmonary disease, atrial fibrillation, diabetes mellitus, multifocal atherosclerosis, acute cerebrovascular accident), erythrocyte sedimentation rate more than 14,5 mm/h, concomitant drug therapy at the time of the intervention (taking of antiarrhythmic drugs, statins). Significant predictors of adverse long­term outcome after planned endovascular myocardial revascularization were clinical complications of PCI, recorded during the hospital period, especially acute periprocedural kidney injury and heart rhythm disorders.

Aim. To study the communicative characteristics of the attending physician, assessed by the patient, and analyze their connection with adherence to the treatment of patients with coronary artery disease (CAD) undergoing coronary artery bypass graft (CABG).

Material and methods. The study included 366 patients — men aged 41 to 77 years old (mean age 59,9±6,9 years) with a stable form of CAD. The patients included in the study were examined 5­7 days before the CABG and 6 months after it. The clinical condition of the patient, the presence of cardiovascular risk factors and the therapy taken before and within 6 months after were assessed. Before being discharged from the clinic, A. А. Leontiev communication card was used to determine the model of communicative interaction.

Results. The higher the patient assessed the communicative competence of the doctor according to the several parameters (“benevolence”, “encouragement of initiative”, “openness”, “activity” and “flexibility”), the higher his adherence to treatment was. Patients who gave a low rating to the attending physician by the communicative parameters (“openness”, “flexibility” and “interest” in communication), had the lowest adherence to treatment.

Conclusion. The adherence to treatment of CAD patients is influenced by such communicative characteristics of the attending physician as “benevolence”, “encouragement of initiative”, “openness”, “activity” and “flexibility” qualify as democratic style of communication between a doctor and a patient.

Aim. To assess the efficiency of guideline for the prevention of hemorrhagic complications in the early postoperative period.

Material and methods. In the period from 2008 to 2017, 166 patients with pathology of the thoracic aorta were operated. The patients were divided into 2 comparable groups: group 1 — patients with reconstructed aortic arch of the type “Hemiarch” (group “hemiarch”, n=90), group 2 — patients with fully reconstructed aortic arch (group “arch”, n=76). All operations were performed with artificial blood circulation, circulatory arrest with moderate hypothermia (25­28° C) and unilateral antegrade cerebral perfusion through the brachiocephalic trunk.

Results. The reconstructions of the thoracic aorta in patients of the “hemiarch” group were accompanied by significantly less period of artificial blood circulation (p=0,027), cardiac arrest period (p=0,012), duration of circulatory arrest (p=0,019), and duration of antegrade brain perfusion (p=0,021). The volume of discharge through the drainage was 350 [192;506] ml and 400 [250;723] ml in the “hemiarch” and “arch” groups, respectively (p=0,29). Patients of the “arch” group more often required transfusion of packed red cells (p=0,003), fresh frozen plasma (p=0,0006), platelet concentrate (p=0,002) in comparison with patients of the “hemiarch” group. At the same time, the frequency of bleeding requiring reoperation was comparable in both groups (5,6% versus 5,3%, p=0,969). The 30­day mortality also had no statistically significant differences in patients of the “hemiarch” and “arch” groups (3,3% versus 9,2%, p=0,119).

Conclusion. The frequency of hemorrhagic complications requiring reoperation in patients with a fully or partially reconstructed aortic arch does not have significant differences when using the guideline for preventing of hemorrhagic complications, which makes it possible to provide acceptable frequency of bleeding episodes and reoperations in the early postoperative period.

Aim.To study a bone mineral density (BMD) in recipients with calcium degeneration and preserved morphofunctional state of heart valve bioprotheses (BP).

Material and methods.The experimental groups included the patients with structural dysfunctions of BP associated with the calcification of the xenomaterial, confirmed by light and electron microscopy data (group I, n=22) and the patients with normal functional state of the implanted valves according to the results of echocardiographic tests (group II, n=48). BMD was assessed by dual energy absorptiometry in the absolute count of mineralized bone and indicators of T­test.

Results. When interpreting the T­test of a femoral neck the severity of osteopenic syndrome prevailed in patients with calcium degeneration of BP (­1,83 [­2,66; ­1,25] in group I vs ­1,47 [­2,51; ­0,86] in group II, р=0,055). At that the mean values of this indicator in patients with the development of calcium­associated BP dysfunctions in the first four years after a surgical correction of the defects reached the diagnostic criteria of the osteoporosis (­2,73 [­3,40; ­2,09] vs ­1,67 [­2,92; ­0,42], р>0,05). According to the result of absorptiometry of the lumbar spine the worst Т­score indicators were also recorded in recipients with the calcification of BP within the first four years of follow­up (­1,75 [­1,83; ­1,43] vs ­0,81 [­0,96; ­0,66] in patients without the signs of calcification, р=0,021). The state of BMD reflects the physiological and pathological processes of calcium redistribution in organism. The existence of the pathogenetic parallels between the activity of bone resorption processes and calcification of the elements of cardiovascular system allows to consider the osteopenia and pathological mineralization of the soft tissues within the framework of a single continuum. The results of the presented work in their turn testify to the determining significance of the severity of osteopenic syndrome manifestations in the development of the “early” calcium degeneration of BP.

Conclusion.Extension of the concepts of the mechanisms and processes which form the pathogenetic basis of mineralization will allow to determine the effective strategies for managing the risk of calcium­associated BP dysfunctions.

Published: December 2018

Renin­angiotensin­aldosterone axis activation is an important mechanism of hypertension and its cardiovascular and renal complications. Angiotensin receptor blockers are considered among the first­choice antihypertensive drugs in Russia, European countries, and the USA. In addition to antihypertensive action, these drugs positively influence several components of the cardiovascular continuum and can be used for individualized management of high cardiovascular risk patients. The paper discusses the benefits of angiotensin receptor blockers use in patients with cardiovascular comorbidities. The paper includes a clinical case scenario revealing antihypertensive efficacy of telmisartan as an initial agent in a patient with high risk of cardiovascular events.

ABSTRACT: The aim of this study was to investigate the influence of fur length in the evaluation of knees temperature in healthy dogs, using infrared thermography. This is a non-invasive diagnosis that is able to assess the microcirculation of the internal skin. Changes in temperature reflect from inflammatory reactions and vascular infarction to neurological disorders. Knees of 30 healthy dogs were analyzed, with up to 11 pounds of weight, screened by clinical examination and radiographic examination. Group A, consisting of 13 dogs with short fur, with 26 knees evaluated in total. Group B included animals with long fur, consisting of 17 animals, with 29 knees evaluated in total. The average temperatures of the cranial, lateral, caudal and medial sides of knees were analyzed. A significant difference between the groups was observed, with group A temperature being greater than the group B in all four analyzed faces. Comparing the temperatures of the faces in the contralateral limb, in both groups, the statistical analysis revealed no significant difference. In group A it was observed that temperatures in the cranial and lateral sides were similar, but different from the others. In group B, the statistical analysis showed the cranial lateral and caudal faces was similar, but differed from the medial side. The thermographic examination proved to be sensitive in the evaluation of temperature of small dogs’ knees;however, the length of the fur influenced the result.

Published: December 2018

ABSTRACT: Phytoremediation is an alternative technique used to treat copper-contaminated soils. The objective of this research was to explore the behavior of nine summer cover crops regarding the growth, absorption and translocation of copper in soils with contamination levels exceeding the Value of Prevention, with a view to selecting plants for phytoremediation programs. In the experiments the Cambisol was contaminated with copper, added in doses of 0, 100, 200, 400, 500 and 600mg kg-1, in which the following nine plants were cultivated under greenhouse conditions: Canavalia ensiformis, Cajanus cajan, Dolichos lablad, Mucuna cinereum, Mucuna aterrima, Crotalaria juncea, Crotalaria spectabilis, Pennisetum glaucum and Paspalum notatum. At 90 days after sowing the plants were evaluated for dry mass of shoot and root, Cu, N, P, K, Ca, Zn, and Fe levels in the shoot and Cu in the roots. High soil Cu levels induced a decline in the phosphorus absorption by the plants. Canavalia ensiformis displayed high potential for phytoextraction as these plants could translocate high copper concentrations to the aerial plant parts, while the Mucuna cinereum and M. aterrima are indicated for the copper phytostabilization programs, due to the high copper accumulation in their root systems.

ABSTRACT: The effect of the incorporation of cinnamon (Cinnamomum cassia) and nut meg (Myristicafragrans) essential oils in alginate-based edible coatings that were applied on minimally processed apples, is reported. The minimum inhibitory concentrations were 1.25mg.mL-1 (cinnamon) and 2.50mg.mL-1 (nutmeg), against both Escherichia coli and Penicillium commune. Over storage periods there was a significant reduction in the E. coli and P. commune counts compared to the control. The extent of enzymatic browning was also significantly reduced in the coated samples. In the coated minimally processed apples sensory tests, the flavor had the lowest rating of the properties analyzed, for both treatments, followed by aroma and firmness.

ABSTRACT: Cysticercosis represents an important public health problem that can cause significant economic losses to the beef industry. The present study aimed to determine the prevalence rate of cysticercosis in cattle and estimate the economic losses to producers associated with this parasitic disease. Data were collected from the official sanitary inspection service of a slaughterhouse located in the city of Uberlândia, Minas Gerais, southeast Brazil, from 2009 to 2016. A total of 358,383 cattle from 46 cities in Minas Gerais, Brazil, were slaughtered, of which 4,243 were infected with cysticercosis (1.18%). A total of 5,194 cysticerci were detected in these carcasses, of which 4,548 (87.56%) were alive and 646 (12.44%) were calcified. Most of the cysticerci were located in the masseter and pterygoid masticatory muscles (72.41%). As to the classification of cysticercosis according to the degree of infection of organs and/or parts affected, mild infection was the most frequently observed (92.36%). Rural producers had a total of R$ 1,755,204.20 (US$ 537,526.80) of economic losses due to bovine cysticercosis during the time span of eight years covered by this retrospective study. The importance of the sanitary inspection of meat in the control of this major zoonotic diseases is emphasized.
LANGUAGE AS SOCIAL PRACTICE: DECONSTRUCTING BOUNDARIES IN INTERCULTURAL BILINGUAL EDUCATION
Authors: Zavala Virginia
Published: December 2018

ABSTRACT Although Peru’s Intercultural Bilingual Education (IBE) program has been attempting to pursue new directions, it still carries many ideologies and practices that have defined it since it started half a century ago. In this article, I discuss the way some of these ideologies and practices related to language are reproduced in a preservice teacher training program in one of the capital city’s private universities, which implements a national policy of social inclusion for Quechua-speaking youth from vulnerable contexts. On the basis of diverse dichotomies (L1/L2, Spanish use/Quechua use, Spanish literacy practices/Quechua literacy practices, Quechua speaker/Spanish speaker), the program produces two types of hierarchized subjectivities: one related to the subject educated in Quechua and another related to the subject educated in Spanish, both coming from a conception of languages as discrete codes that go together with fixed ethnolinguistic groups and bounded cultural practices (GARCÍA et al., 2017). In the context of new sociocultural dynamics and bilingualisms, young students in the program subvert these divisions and begin to trace new paths for IBE and Quechua in Perú.

Published: December 2018

Abstract The objective of this study was to evaluate the food safety performance of food services and its associated factors. The study involved 84 food businesses in the city of Santos as follows: street food kiosks and beach kiosks (street food), commercial restaurants, hospitals and school meal services (institutional food services). A food safety checklist with 81 items was applied. The overall percentage of adequacy was lower in street food kiosk (49.7%) and beach kiosk (62.0%) than in restaurants (69.7%), hospitals (83.9%) and schools (86%). Institutional and commercial restaurants showed higher scores of food safety performance than street food services, mainly regarding risker practices. The variables positively associated with food safety performance in commercial restaurants were: presence of a nutritionist as leader and adequate structure. These results show that street food services need, in a mediate way, the implementation of new strategies and regulations to improve food safety. A nutritionist acting as food safety leader may improve the food safety performance at commercial restaurants.

Abstract: This paper presents a study of the hunting activities on Xerente Indigenous Land (XIL) in the Brazilian Cerrado. We used data from a Hunting Monitoring Program from eight villages to evaluate the effects of village age, distance from village to town and season (wet and dry) on the composition of hunted species, animals and biomass killed and availability of preferred game-species. We also assessed for any indication of fauna depletion around the villages. Distance from village to town and season were the only variables which affected composition. Preferred species occured more often in villages closer to the town. However, these villages present strong indications of local game-species depletion. The hunters' great capacity for spatial movement can eliminate this effect. Animals and biomass killed was high in the dry season. Game-species composition between seasons can avoid the overexploitation of some sensitive species, such as low-land tapir. These results are important in the design of local management and conservation plans. Our results also contribute to further understanding the impacts of hunting in open Neotropical environments.

ABSTRACT We report an observation of predation by an Amazon tree boa, Corallus hortulanus, on an American fruit-eating bat, Artibeus sp., in an area of seasonal forest close to a small stream in the northern Brazilian Amazon. While bats appear to be one of the main food items of C. hortulanus, our observation is only the fourth such event to be recorded in the Brazilian Amazon. The Artibeus sp. individual was observed making distress (agony) calls continuously over a period of three hours, much longer than recorded on previous observations. Records of this type are important to further our knowledge on bat predators, and the defensive behavior of bats.

Published: December 2018

ABSTRACT Cranioencephalic trauma which results in extensive edema and / or bruising usually requires surgical treatment through a greater withdrawal of the bone portion. Thus, the absence of bone tissue implies the lack of protection of the brain tissue or even compromises the esthetics especially when located in the frontal or frontoparietal region. The purpose of this case report is to describe a treatment option for head trauma, through the prefabricated part by obtaining the skull model. These bone faults can be reconstructed either by the direct method using polymethylmethacrylate directly on the defects or by means of pre-made pieces such as prototyping or from the skull model. Although other techniques have many good points, some show certain drawbacks, from storage conditions below abdominal fat, preheating due to the release of heat during the high polymerization reaction or the high cost when they are prototyped. The technique described in this work reports its simple performance, eliminating the risk of local heating, allows prior sterilization in autoclave, it is biocompatible, allows perfect anatomical recovery, easy placement, low cost, also highlighs the advantage of the bucomaxillofacial surgeon's performance due to the familiarization with the relevant head and neck procedures. Clinical and tomographic examination after 24 months of treatment showed stability of the polymethylmethacrylate plate, adhesions to the bone margins, and absence of tissue alterations.
Cytogenetics of two Farlowella species (Loricariidae: Loricariinae): implications on the taxonomic status of the species

Published: December 2018

ABSTRACT Farlowella is one of the most diverse genera of the Loricariinae, restricted to South America rivers. The taxonomic and phylogenetic relationships among its species are contentious and, while genetic studies would contribute to the understanding of their relationships, the only available datum refer to the karyotype description of only one species. In the present study two Amazonian species, Farlowella cf. amazonum and F. schreitmuelleri, were analyzed using conventional and molecular cytogenetic procedures. Both species had diploid chromosome number 58, but different fundamental numbers (NF) 116 and 112, respectively, indicative of chromosomal rearrangements. C-banding is almost poor, especially in F. cf. amazonum, and occurs predominantly in the centromeric and in some telomeric regions, although genome of F. schreitmuelleri possessed a much larger heterochromatin amount then those of F. cf. amazonum. The chromosomes bearing the NOR sites were likely the same for both species, corresponding to the 1st metacentric pair in F. cf. amazonum and to the 28th acrocentric in F. schreitmuelleri. The location of the 5S rDNA was species-specific marker. This study expanded the available cytogenetic data for Farlowella species and pointed the remarkable karyotype diversity among species/populations, indicating a possible species complex within genus.

ABSTRACT This study aimed to establish an adequate tetrazolium test procedure to estimate okra seed viability. Initially, seeds from four okra lots were immersed in alcohol (98%) for 60 minutes, followed by an 18-h soak in distilled water at 25 °C. Then, the seeds were longitudinally sectioned, immersed in 0.025, 0.050 and 0.075% tetrazolium solutions for 60, 90 and 120 minutes and maintained in an oven at 35 and 40 °C. Subsequently, the seeds were evaluated for viability, based on tissue color (bright red, pink or dark Carmine red). Simultaneously, a germination test was conducted, and its results were used as a reference for the tetrazolium test. The experiment was carried out in a completely randomized design, in a 3 x 3 + 1 factorial scheme (three concentrations of tetrazolium salt x three immersion periods, plus the control) in four replicates of 50 seeds for each treatment. The tetrazolium test to estimate okra seed viability should be conducted in 0.075% tetrazolium solution, for 90 minutes, at 35 °C.

ABSTRACT Maize is an important cereal and it is widely consumed in the world, both as food for humans and animals. Nitrogen (N) is a nutrient required in large quantities by maize, but unfortunately, soils are limited in meeting this need. Nodulating legumes can serve as a source of Nitrogen, because they are symbiotically associated with bacteria capable of fixing atmospheric N. Another important source of this nutrient is cattle manure, which is widely used in agriculture. The objective of the present study was to evaluate the effect of using legumes and cattle manure on the production as well as the microbial and biochemical quality of the soil used for maize cultivation. The experiment was conducted using a randomized complete block design, in a sub-subdivided plot scheme [(2x4) +2], two leguminous plants (pigeon pea and macassar bean), four doses of cattle manure (0, 20, 40 and 60 t ha-1) and two controls; one with mineral fertilization and the other cultivated without the use of fertilizers. Treatment using a manure dose of 60t ha-1 and pigeon pea legume, recorded higher dry mass production per plant. The increase in manure doses was directly proportional to the length and weight of the cobs for the two legumes. The enzymatic activities were affected by the different doses and legumes, with greater results being recorded at the 60 t ha-1 dose with the macassar legume. The use of legumes with manure improved maize production as well as the microbiological and biochemical quality of soils.

ABSTRACT In Brazil, studies on chickpeas (Cicer arietinum L.) have demonstrated the high productive potential of this crop, especially in the Cerrado areas of Cristalina, GO, and Brasília, DF. Due to dry winter climatic conditions, the North of Minas Gerais may be very suitable for the production of this crop. However, more information on chickpea sowing dates is needed. Therefore, the objective of the present study was to evaluate different chickpea sowing times in two municipalities of Minas Gerais State in Brazil: Montes Claros and Januária. The experiment was carried out in a randomized block design, comprising three sowing dates (12 May, 23 June, and 22 July, 2015), and seven replications. The cultivar used was BRS Aleppo, and the chickpeas were harvested 121 days after sowing. The variables evaluated included plant height, productivity, number of pods with one grain, and number of pods with two grains. The data were submitted to analysis of variance, and joint analysis of the experiments was performed. The highest yields were obtained when chickpeas were sown in May in Montes Claros, with a yield of 5.3 t ha-1. In Januária, chickpeas sown in May and June produced yields greater than 3.0 t ha-1. The plants sown in July, considered late for planting, were harvested during the rainy season, which compromised the quality and yield of the grains. In addition, maximum temperatures above 30ºC were recorded from September onwards in both locations, which also resulted in a reduction in the number of grains per plant. Thus, this sowing season is not recommended in the studied region.

ABSTRACT The Northeast region of Brazil has the second highest number of species of the Myrtaceae family. It is mostly covered by the Caatinga biome, which is very degraded, making it difficult to preserve species of this family. Thus, the objective of this work was to describe the seed, seedling, and fruit morphology, and seed germination of Psidium sobralianum Landrum & Proença plants of the São Francisco Valley, Brazil. The fruits were collected in an area of the Brazilian Agricultural Research Corporation (Embrapa Semiarid), in Petrolina PE, Brazil. The evaluations consisted of determinations of fruit shape, consistency, and number of seeds; seed form, cotyledons, hilum, hypocotyl-radicle axis, and embryo type; epicarp, mesocarp, endocarp, and seed staining; longitudinal, transversal, and ventral diameters of fruits and seeds; fruit, pulp, and seed fresh and dry masses; germination test; first count of germinated seeds; germination speed index; shoot and root lengths; shoot and root fresh and dry masses; and imbibition test. Psidium sobralianum has polyspermic, berry fruits, subclassified as solanidium, with persistent sepals and globular shape, consisting of epicarp, mesocarp, endocarp and seeds. The fruits have green with orange epicarp, pale-green mesocarp, and white endocarp. The seeds have a pilose and bony aspect, a pimentoid type of embryo, foliaceous cotyledons, presence of operculum and hilum, and pale-yellow tegument. The germination is epigeal phanerocotiledonar, with root protrusion from 26 days after sowing (DAS); it presents a short, glabrous, thick radicle, and a rounded, pale-green apex. The germination is slow, probably due to the mechanical barrier of the tegument, and stabilizes at 90 DAS.

ABSTRACT The semi-arid region accounts for about 70% of the surface area of the Brazilian northeast, and the most important forage resource is the Caatinga, covering approximately 54% of this region. However, about 40% of this vegetation is in secondary succession. The areas in the process of degradation range from low to severe intensity, and total more than 20 million hectares, reflecting the intense use of the land, such as the overgrazing. The objective of this study was to evaluate the influence of different doses of phosphorus (0, 50 and 100 kg P2O5 ha-1 year-1) on the dynamics of herbaceous vegetation at different times of the year, in a Caatinga area manipulated without grazing for four years. The experiment was conducted at the Serra Talhada-UFRPE Academic Unit during the years 2015 and 2016. We used a randomised block design with three blocks and four replicates per block. Phosphate fertilisation in grazing exclusion areas promoted an increase in forage mass of the enriched Caatinga herbaceous stratum at all evaluation times, especially in the dry season of 2016, which showed values above the average of 7950 kg DM ha-1. In addition, it promoted an increase in the participation of buffelgrass in the floristic composition, increasing its involvement in the area to around 74% at the maximum dose of phosphorus used. Thus, phosphate fertilisation at up to 100 kg of P2O5 ha-1 year-1, together with grazing exclusion, can help to recover the Caatinga enriched with buffelgrass and optimise its use by reducing the formation of new grazing areas in the Caatinga.

ABSTRACT New hybrid onions that are more productive are currently being cultivated. Information on growth and nutrient accumulation must thus be updated to assist in the refinement of existing recommendations, enabling the better exploitation of the productive potential of these new genotypes. We determined the growth of plants and the accumulation and export of nutrients of the short-day onion ‘Soberana’ established by direct seeding. The experimental design was a randomized block with four replicates and the treatments were evaluation times. Leaf number, tissue dry weight, nutrient accumulation, and the maximum daily rate of accumulation were evaluated throughout the growing cycle. The order of nutrient accumulation was (g plant-1) K (0.72) > Ca (0.38) > N (0.32) > S (0.14) > P (0.08) > Mg (0.06) and (mg plant-1) Fe (2.26) > Mn (1.43) > Cu (0.93) > Zn (0.91) > B (0.85). Macronutrient demand was highest between 61 and 148 days after sowing (DAS), and micronutrient demand was highest between 70 and 148 DAS.

Published: December 2018

ABSTRACT Common beans (Phaseolus vulgaris L.) are one of the most important protein sources worldwide. However, infestation by bruchids compromises the storage of these beans after harvest. The objective of this study was to determine the emergence rate of Zabrotes subfasciatus (Coleoptera: Chrysomelidae) in four P. vulgaris varieties (Carioca Pitoco, Enxofre, Gorgutuba Vermelho, and Rosinha) cultivated in the southwestern Amazon (State of Acre, Brazil). The grains from each variety were infested with 50 non-sexed adult Z. subfasciatus, and the insects were collected 13 days after initiating the bioassays. The adult progeny was collected from each plant variety on alternate days from the beginning to the end of the emergence period, and they were counted (number of insects/jar). The sum of emerged insects per day (SEd) was determined from the beginning of the emergence period, from which the accumulated emergence was calculated (SEa= ΣSEd, % day). There were differences in the emergence rates of Z. subfasciatus among the bean varieties, with the rates being lower in the Gorgutuba Vermelho variety. Although this bean variety had the lowest peak of adult insect emergence, the period of insect development was not of increased length in this variety compared to the other varieties. In general, the Gorgutuba Vermelho variety appears to be resistant to Z. subfasciatus.

ABSTRACT The objective of this study was to evaluate the efficiency, phytotoxicity and residual effect of the aqueous extract of leaves of Prosopis juliflora (Sw.) DC (Fabaceae) for Tetranychus bastosi Tuttle, Baker & Sales (Acari: Tetranychidae) on Jatropha curcas L. (Euphorbiaceae). For the evaluation of the control efficiency, physic nut plants were infested with 30 adult mite females and after 12 days were sprayed with the lethal concentrations (m/v) of the extract (LC50 = 53.45% or CL90 = 85.35%) and with distilled water (control), which corresponded to the treatments. After 24, 48, 72, 96 and 120 hours after application of the extract, two leaves of the lower, middle and upper third of the plants were sampled and the live mites were counted per treatment. The evaluation of the residual effect was done three, 24, 48, 96, 192 and 288 hours after spraying. To evaluate the phytotoxic effect of the extract, scores were given according to the intensity of the symptoms in the plants. Control efficiency was verified throughout the evaluated period, with an average of 81.67% for LC50 and 73.05% for LC90, with no significant difference between the evaluation intervals. The extract had a low residual effect on T. bastosi, but at the end of 12 days the average percentage of oviposition reduction of mite was 49.21% and 68.86% for LC50 and LC90, respectively. The plants did not present phytotoxicity. P. juliflora extract presents potential for the alternative control of T. bastosi in physic nut due to its efficiency on the mortality of this mite, oviposition reduction of females and absence of phytotoxic effect in the plants.
A Network-wide visualization of the implementation of the Global Strategy for Plant Conservation in Brazil
Authors: Dalcin Eduardo , Jackson Peter Wyse
Published: December 2018

Abstract This paper describes a visualization approach of the existing network available in Brazil to achieve the targets of the Global Strategy for Plant Conservation (GSPC) for 2020 in Brazil. The approach uses the Brazilian National Biodiversity Strategies and Action Plans and other key documents to identify and map institutions, roles and actions related to each of the GSPC targets. The visualization was generated using the Gephi, an open source software for exploring and manipulating networks. The visualization presented shows some GSPC targets supported by an effective network of institutions, but also GSPC targets that lack of proper support. This visualization approach may be useful to indicates gaps, opportunities for new actions and areas where network linkages may be extended to achieve the GSPC targets more fully in other countries too.

Abstract In South American rivers, Eichhornia crassipes and other floating plants intertwine and form floating rafts commonly known as "camalotales" which are especially abundant during flooding periods. During extraordinary floods, hectares of floating mats are drifted by the Plata Basin Rivers. In the Río de la Plata several reports suggest that many animal and plant species from subtropical latitudes colonizes the area through these large rafts. These episodes are very important from the economic point of view because they cause several troubles to navigation and other activities. On the other hand, benefits to biodiversity are conspicuous, and many authors consider this process vital to the Río de la Plata wetlands and forests. However, there is scarce knowledge about Eichhornia rafts plant species composition. With the aim of creating an exhaustive list of the flora of the Eichhornia rafts, we visited the Río de la Plata coast during a massive Eichhornia rafts arrival. Thirty-two plant species were recorded in three different plant assemblages: Eichhornia rafts sensu stricto, floating reeds (canutillares) and embalsados. In front of this unexpected we emphasize the need to include this phenomenon in regional biodiversity conservation plans.

Resumo Na primeira parte deste texto, debruço-me sobre as noções de cidadania e de sociedade civil, procurando mostrar de que forma elas evoluíram historicamente uma em relação à outra. A seguir, mostro de que forma um novo tipo de contrato social – o chamado welfare state – surgiu nos países demo-liberais após a crise de 1929 e a Segunda Guerra Mundial. No termo dessa reflexão, identificarei a noção de capital social como veículo privilegiado dos processos sociais de inclusão versus exclusão. Por fim, apresentarei os resultados de um inquérito internacional que permite identificar as características comparativas dos modernos processos de associativismo, mobilização e mudança sociocultural.
