title: Silicon foliar application attenuates the effects of water suppression on cowpea cultivars

description: ABSTRACT Silicon and proline play important physiological, metabolic and functional roles in plants, especially under water deficit conditions. Their application can mitigate the adverse effects of stress in crops by increasing water use efficiency and antioxidant activity. The objective of this study was to evaluate silicon (Si) as attenuator of the effects of water deficit on cowpea cultivars, through physiological, biochemical and growth indicators. The experimental design was randomized blocks with four cultivars (BRS Guariba, BRS Itaim, BRS Aracê and BRS Rouxinol) and four irrigation treatments associated or not with Si application (W100 - 100% ETo; W50 - 50% ETo; W50+100Si and W50+200Si, with 100 and 200 mg L-1 silicon, respectively), in a 4 x 4 factorial scheme, with five replicates. Leaf water potential, proline concentration, antioxidant enzymes and growth indicators were evaluated in cowpea plants. Under water deficit conditions, all cultivars showed reductions in leaf water potentials, which compromised plant growth. However, Si applications of 200 mg L-1 in the cultivar BRS Guariba and 100 and 200 mg L-1 in the cultivar BRS Itaim minimized the effects of stress, by increasing leaf water potential and the activity of the enzyme ascorbate peroxidase, in both cultivars, besides increasing proline concentration in the former and reducing proline concentration in the latter, which ensured the maintenance of growth. Despite the no contribution to the increase in water potential, Si applications of 100 and 200 mg L-1 in BRS Rouxinol and BRS Aracê, respectively, reduced the deleterious effects of the stress on their growth by regulating the enzymatic metabolism and proline.

title: Morphology and distribution of the freshwater mussel Diplodon granosus, a rare and poorly understood species

description: ABSTRACT Diplodon granosus was one of the first freshwater mussels to be described for South America. However, the status of the species was confusing for a long time, receiving different taxonomic treatments. In this paper, we redescribe the shell, with new data on the soft parts and information on the distribution and conservation of D. granosus, a rarely recorded species. The shell is thin, not inflated; the macrosculpture is composed only by granules that cover the whole shell, not forming bars; the microsculpture comprises short spikes. In the soft parts we highlight the few, weak and irregularly distributed lamellar connections of the outer demibranch and some features of the stomach, such as the distally enlarged minor typhlosole. There are records of D. granosus over a large area of South America, from Guiana to Argentina. However, most of these records are related to other species and the distribution of D. granosus is restricted to the north of South America in the basins of the Amazonas and Orinoco rivers, and coastal rivers in between. Despite this wide distribution, the species occurs in specific habitats, mainly streams (igarapés), resulting in an extremely fragmented occurrence. Thus, any disturbance to these habitats can threat this freshwater mussel.

title: Extended use of poultry manure as a nutrient source for flood-irrigated rice crop

description: Abstract: The objective of this work was to evaluate changes in the soil chemical properties, nitrogen use efficiency, and grain yield of flood-irrigated rice fields after the addition of poultry manure during five years. Trials were carried out in a randomized complete block design, with three replicates. The treatments were: chemical fertilizers, N-P2O5-K2O; control, no fertilizers; and poultry manure doses, 2.5, 5.0, and 10.0 Mg ha-1. Poultry manure increased soil pH, base saturation, and phosphorus, potassium, calcium, and zinc contents more than the chemical fertilizers. Adding poultry manure to the soil increased N ammonification (35 mg kg-1 NH4 +-N) from the first to the fourth week after rice was sown. The exclusive use of poultry manure was not sufficient to provide adequate nutrition to rice plants after the decrease in NH4 +-N content in the soil. The cumulative N uptake by plants and rice yield were lower with poultry manure application than with the chemical fertilizers. Adding poultry manure to flood-irrigated rice fields for five years alters soil chemical properties, improves fertility, does not favor nitrogen use efficiency by rice plants, and promotes a lower grain yield than the chemical fertilizers.

title: Antiretroviral drug use by individuals living with HIV/AIDS and compliance with the Clinical Protocol and Therapy Guidelines

description: ABSTRACT Objective To describe antiretroviral treatment regimens prescribed and their compliance with the Clinical Protocol and Therapy Guidelines of the Ministry of Health for the management of HIV infection. Methods Observational and descriptive study. Secondary data of the state of Paraná (Brazil) on drugs, treatment regimens, lines of treatment and number of individuals on treatment, from January to June 2018, were accessed at the Antiretroviral Agents Logistic Control System. Combinations of antiretroviral drugs (treatment regimens) were compared according to the current Clinical Protocol and Therapy Guidelines and non-compliances were classified and quantified. Results In Paraná, 35,127 individuals with HIV were treated with 253 different treatment regimens. Of the prescribed regimens, 19.1% were first-line, 27.4% second-line and 48.5% third-line. Among non-compliances, the most prevalent were absence of association of protease inhibitors and ritonavir (42.8%), low efficacy triple therapy (36.9%), double therapy (26.1%), monotherapy (20.3%), and triple therapy of nucleoside analog reverse transcriptase inhibitors (17.1%). Conclusion Most individuals receiving HIV treatment in the state of Paraná are on treatment regimens established in the current Clinical Protocol and Therapy Guidelines, which contributes to successful therapy. However, associations not provided by the current Clinical Protocol and Therapy Guidelines were identified in the initial treatment lines, which could lead to ineffectiveness, virologic failure and viral resistance.

title: Prevalence of eating disorders risk behavior and “low-carb” diet in university students

description: ABSTRACT Objectives To identify the presence of binge eating associated or not with compensatory practices in low-carb dieters. Methods Binge Eating Scale (BES) and Hay Questionnaire were used in order to assess the frequency of binge eating and compensatory practices, in addition to a frequency questionnaire for the consumption of chocolate, bread and rice. A scale of 1-8 points assessed the carbohydrate restriction intensity, and participants were divided into groups (i) low-carb diet and (ii) control. Comparisons between groups were part of the analysis, as well as correlations between variables of interest per diet group (p &lt; 0.05). Results Participants were a total of 853 university students, in which 75.97% were women with an average of 22.04 years old (SD = 3.33) and an average BMI of 23.56 kg/m2, (SD = 4.38). From the aforementioned total, 214 had a low-carb diet, and 639 did not. The prevalence of a high score suggestive of binge eating without compensatory practices was 17.94% (n = 153), while the presence of binge eating associated with compensation was 2.23% (n = 19). As for the diet group, 35.05% (n = 75) also performed intermittent fasting. The diet group reached higher values for ECAP and BMI, and lower for frequency of consumption of rice and bread. Furthermore, ECAP scores correlated positively with chocolate consumption (r = + 0.14; p = 0.0377) and BMI values (r = + 0.19; p = 0.0042), whereas carbohydrate restriction showed negative correlation with chocolate consumption (r = - 0.13; p = 0.041); French bread (r = - 0.20; p = 0.0024) and rice (r = - 0.36; p = &lt;0.0001). Conclusions We highlight the high prevalence of diet practice (25.09%), and the higher levels of binge eating in this group, as well as the lower consumption of rice and bread compared to those who did not diet.

title: Intercropping maize and cowpea cultivars: I. Green-grain yield

description: ABSTRACT Green ears of maize are much appreciated all over Brazil and reach higher prices than dry grain. This also occurs with green cowpea grain, which is much appreciated in the north and northeast of the country. The aim of this study was to identify maize and cowpea cultivars that can be grown as monocrops or intercrops to produce green grain in the state of Pará (PA). An experiment was carried out in a randomized block design with six replications in Marabá, PA. Monocrops of traditional varieties of the cowpea (‘Corujinha’ and ‘Sempre Verde’) and the maize cultivars (‘AG 1051’ and ‘AL Bandeirante’), and four alternating, intercropped rows of a combination of the varieties and cultivars were evaluated. The ‘AG 1051’ cultivar was more productive than the ‘AL Bandeirante’ cultivar, as both a monocrop and an intercrop. The cowpea cultivars showed a similar performance under both systems of cultivation. There was no interaction between the maize cultivars and cowpea cultivars. The monocrops were superior to the intercrops for green-ear, green-pod and green-grain yield. Considering the land equivalent ratio, if the aim is to produce green pods, intercropping is only beneficial in the AG 1051 + Corujnha combination. If the aim is for green-grain yield in the cowpea, intercropping is more advantageous when the ‘AG 1051’ cultivar is combined with any cowpea cultivar. The intercrop including the ‘AL Bandeirante’ cultivar is only beneficial with the ‘Corujinha’ cultivar, and if the aim is to market unhusked, green ears of maize.

title: Stream fish from recently deforested basins in the Meridional Amazon, Mato Grosso, Brazil

description: Abstract: The replacement of tropical forests to production systems is one of the leading causes of riverine ecosystem alterations. However, current assemblages’ composition may also result from the time since these transformations have begun. Therefore, the knowledge of diversified historical scenarios can facilitate the accomplishment of actions that involve the aquatic environments recovery. In this study, an inventory of stream fish was carried out in basins whose deforestation was intensified in the last 20 years, to compose a baseline for ecological and taxonomic studies. The habitat, physical and chemical variables, and the fish assemblages from 60 streams in the northwest region of the state of Mato Grosso, in the Aripuanã and Juruena river basins, were sampled with standardized procedures. For a total of 130 species, a numerical predominance of small-sized Characidae and great rarity were registered, with 50 species represented by less than ten individuals and 19 singletons. Approximately 15% of the sampled taxa were identified only at the generic level, and for several taxa, more detailed taxonomic and molecular studies are required in order to achieve satisfactory identifications. None threatened species were so far reported. On the other hand, two specimens of non-native species were sampled. Although habitat quality is higher in forested streams, no differences in the species richness were registered when compared to the pasture with riparian forest streams or to more deforested streams. However, abundance was greater in these last two streams groups as a result of small-sized characins dominance.

title: INDIUM: A SCIENTIFIC AND TECHNOLOGICAL VIEW OF A STRATEGIC METAL

description: Indium have been widely investigated by scientists because of its several interesting properties and its use in different applications in the manufacture of TVs screens, computers, cell phones, solar panels, electroluminescent diodes (LEDs), organic electroluminescent diodes (OLEDs), DNA and antibody sensors, electrocatalysts, architectural glass coatings, low melting alloys, thermal interface materials, aircraft engine bearings, among others. The economic urge to make devices more cost effective and efficient has guide developments in different deposition technologies, such as dip-coating, plating, thick and thin film deposition. However, indium is classified as a critical metal. In this sense, we discussed the economic viability and spatial distribution of the indium resources in Brazil and worldwide considering that its supply still remains a concern. On top of that, the present review discusses the scientific and technological aspects of indium materials and highlights the major advances regarding their synthesis, properties and applications.

title: Novel insights into chromosome evolution of Charadriiformes: extensive genomic reshuffling in the wattled jacana (Jacana jacana, Charadriiformes, Jacanidae)

description: Abstract The order Charadriiformes comprises three major clades: Lari and Scolopaci as sister group to Charadrii. Until now, only three Charadriiformes species have been studied by chromosome painting: Larus argentatus (Lari), Burhinus oedicnemus and Vanellus chilensis (Charadrii). Hence, there is a lack of information concerning the third clade, Scolapaci. Based on this, and to gain a better understanding of karyotype evolution in the order Charadriiformes, we applied conventional and molecular cytogenetic approaches in a species belonging to clade Scolopaci - the wattled jacana (Jacana jacana) - using Gallus gallus and Zenaida auriculata chromosome-specific probes. Cross-species evaluation of J. jacana chromosomes shows extensive genomic reshuffling within macrochromosomes during evolution, with multiple fission and fusion events, although the diploid number remains at high level (2n=82). Interestingly, this species does not have the GGA7-8 fusion, which was found in two representatives of Charadrii clade, reinforcing the idea that this fusion may be exclusive to the Charadrii clade. In addition, it is shown that the chromosome evolution in Charadriiformes is complex and resulted in species with typical and atypical karyotypes. The karyotypic features of Scolopaci are very different from those of Charadrii and Lari, indicating that after divergence, each suborder has undergone different chromosome rearrangements.
