title: Criteria for Decision Making and Economic Threshold Level for Wild Radish in Wheat Crop

description: ABSTRACT: Weed competition limits wheat yield by reducing the availability of essential resources for its growth and development. In this sense, this study aimed to estimate the economic threshold level (ETL) of wild radish (Raphanus raphanistrum) in competition with wheat cultivars. Treatments were arranged in a factorial scheme. The factor wheat cultivar consisted of early (BRS 328), medium (BRS 177), and late (BRS Umbu) cycles and the factor wild radish population ranged from 0 to 564 plants m-2 (10 populations) for the cultivar BRS 328, 0 to 472 plants m-2 for the cultivar BRS 177 (11 populations), and 0 to 724 plants m-2 for the cultivar BRS Umbu (10 populations). The early-cycle BRS 328 presented a higher competitive ability when compared to the medium-cycle BRS 177 and late-cycle BRS Umbu. Yield losses of wheat grains due to wild radish interference can be satisfactorily estimated by the rectangular hyperbola model using the variables plant population, shoot dry matter, soil cover, and leaf area of the weed. ETL values varied as a function of the cultivar cycle, being higher for the cultivar BRS 328 (early) &gt; BRS 177 (medium) &gt; BRS Umbu (late). Wild radish is competitive in wheat crop, requiring at least 1.6 plants m-2 for control to be justified.

title: Temporal and spatial distribution of American tegumentary leishmaniasis in north Paraná: 2010-2015

description: Abstract INTRODUCTION: Describing the general aspects of American tegumentary leishmaniasis enables the identification of the epidemiological scenario of the disease and the development of preventive actions. METHODS: We analyzed the records of patients with American tegumentary leishmaniasis in north Paraná between 2010 and 2015. RESULTS: We identified 108 cases (mostly in 2014) with the following characteristics: male individuals, rural workers, and ages averaging 56.8 years. Isolated ulcerated lesions were predominant, and Glucantime® was the most frequently used drug. CONCLUSIONS: American tegumentary leishmaniasis remains endemic and affects mostly men found in areas surrounded by woods; its treatment is partially efficient considering its side effects and incidence of recurrences.

title: Large-Scale Spatial and Temporal Variability of Larval Fish Assemblages in the Tropical Atlantic Ocean

description: Abstract This study investigated the large-scale spatial and temporal variability of larval fish assemblages in the west tropical Atlantic Ocean. The sampling was performed during four expeditions. Identification resulted in 100 taxa (64 families, 19 orders and 17 suborders). During the four periods, 80% of the total larvae taken represented eight characteristics families (Scombridae, Carangidae, Paralepididae, Bothidae, Gonostomatidae, Scaridae, Gobiidae and Myctophidae). Fish larvae showed a rather heterogeneous distribution with density at each station ranging from 0.5 to 2000 larvae per 100m3. A general trend was observed, lower densities at oceanic area and higher densities in the seamounts and islands. A gradient in temperature, salinity, phytoplankton biomass, zooplankton biomass and station depth was strongly correlated with changes in ichthyoplankton structure. Myctophidae, and Paralepididae presented increased abundance at high salinities and temperatures. Bothidae and Gobiidae were more abundant at higher phytoplankton biomass and zooplankton biomass. Scaridae, Scombridae and Gonostomatidae had higher abundances at deep offshore stations. Different events might be responsible for the formation, maintenance and breakdown of fish larvae assemblage in the tropical oceanic area of Brazil. The results suggested that the oceanographic variables (temperature, salinity, phytoplankton biomass, zooplankton biomass and station depth) played an important role on the distribution patterns of ichthyoplankton.

title: FROM COMPLEX EVOLVING TO SIMPLE: CURRENT REVISIONAL AND ENDOSCOPIC PROCEDURES FOLLOWING BARIATRIC SURGERY

description: ABSTRACT Background: Roux-en-Y gastric bypass (RYGB) is a standard therapy in bariatric surgery. Sleeve gastrectomy and gastric banding, although with good results in the literature, are showing higher rates of treatment failure to reduce obesity-associated morbidity and body weight. Other problems after bariatric may occur, as band erosion, gastroesophageal reflux disease and might be refractory to medication. Therefore, a laparoscopic conversion to a RYGB can be an effective alternative, as long as specific indications for revision are fulfilled. Objective: The objective of this study was to analyse own and literature data on revisional bariatric procedures to evaluate best alternatives to current practice. Methods: Institutional experience and systematic review from the literature on revisional bariatric surgery. Results: Endoscopic procedures are recently applied to ameliorate failure and complications of bariatric procedures. Therapy failure following RYGB occurs in up to 20%. Transoral outlet reduction is currently an alternative method to reduce the gastrojejunal anastomosis. The diameter and volume of sleeve gastrectomy can enlarge as well, which can be reduced by endoscopic full-thickness sutures longitudinally. Dumping syndrome and severe hypoglycemic episodes (neuroglycopenia) can be present in patients following RYGB. The hypoglycemic episodes have to be evaluated and usually can be treated conventionally. To avoid partial pancreatectomy or conversion to normal anatomy, a new laparoscopic approach with remnant gastric resection and jejunal interposition can be applied in non-responders alternatively. Hypoglycemic episodes are ameliorated while weight loss is sustained. Conclusion: Revisional and endoscopic procedures following bariatric surgery in patients with collateral symptomatic or treatment failure can be applied. Conventional non-surgical approaches should have been applied intensively before a revisional surgery will be indicated. Former complex surgical revisional procedures are evolving to less complicated endoscopic solutions.

title: SLEEVE GASTRECTOMY IN PATIENTS WITH MORBID OBESITY AND HIV

description: ABSTRACT Introduction: It is estimated that there are nearly 40 million people with the human immunodeficiency virus (HIV) worldwide. Due to the advent of antiretroviral drugs, it has been observed increasing in obesity and metabolic rates among patients undergoing treatment. Thus, numerous surgical therapies for weight loss are proposed for continuous improvement in health of patients with HIV, being the vertical gastrectomy an option for intact intestinal transit. Objective: To evaluate the applicability of the vertical gastrectomy in patients with morbid obesity and HIV. Methods: Was conducted a systematic review of the literature, in the electronic databases Scopus, Pubmed, Cinahl, Scielo, Cochrane and Lilacs, from 1998 to 2015. MeSH headings used in data collection were "Gastrectomy" and "Morbid obesity" being combined with the descriptor "HIV". Were found 2148 articles in Scopus, 1234 in PubMed and 784 in Cinahl. The articles were analyzed by the Jadad Quality Scale, being reduced to 40 articles, subsequently reassessed using an elaborated form by the Critical Appraisal Skills Programme (CASP), reaching 12 articles in the end. Conclusion: It was found that vertical gastrectomy constitutes a safe and effective method, with low mortality and low rate of postoperative complications, being recommended as surgical technique in patients with obesity, HIV and comorbidities.

title: Gene Deletion Leads to Improved Valinomycin Production by Streptomyces sp. CBMAI 2042

description: The genus Streptomyces represents one of the largest producers of molecules with antibiotic activity. The whole genome sequencing of the endophytic microorganism Streptomyces sp. CBMAI 2042 revealed 35 gene clusters encoding for secondary metabolism including 3 non-ribosomal peptide synthetases (NRPS) and 7 NRPS-hybrids. Combining genome mining and cultivation profile analysis, the depsipeptide ionophore valinomycin was identified as one of the main metabolites produced by this strain. To better understand the metabolic machinery codified in CBMAI 2042 genome an adenylation domain from a hybrid NRPS cluster was deleted through a double crossing knockout experiment. Though the deletion was not plentiful to elucidate the encoded NRP metabolite related to the adenilation domain, an astounding increase of 10.5-fold in valinomycin production was observed in the mutant. These results suggest a metabolic flux redistribution of common substrates as an outcome of a gene target deletion.

title: Reproductive performance of fixed-time artificial insemination in swine and factors for the technology success

description: ABSTRACT: Fixed-time artificial insemination (FTAI) is a reproductive technology that aids in obtaining an appropriate time to perform single artificial insemination (AI), thus reducing the number of inseminations per sow bred. FTAI protocols can either be based on estrus detection or day of weaning, aiming to synchronize ovulation using ovulation inducers. The protocols involving estrus detection usually employ porcine luteinizing hormone (pLH) as an inducer and, in general, satisfactory reproductive performance is observed. For protocols based on weaning day, the main hormone used is analog of gonadotropin-releasing hormone such as triptorelin and buserelin. Regardless of the protocol, the number of piglets born is usually not affected by FTAI. However, a possible compromise in the farrowing rate should be considered. The FTAI in gilts requires progestogen treatment for estrus synchronization, increasing the labor requirement and cost of protocol. Some of the benefits of FTAI are a reduced number of semen doses required, advantage of planning the breeding time and; consequently, optimizing labor involved. However, the limitations include a slight reduction in the fertility index due to the compromised farrowing rate in some cases, costs incurred by following the protocol, and difficulty in measuring all the conceptual benefits under commercial conditions. The aim of this review is to approach the reproductive performance of the current protocols of FTAI, considering the benefits and limitations of this technology in swine production.

title: Community ecology of parasites in four species of Corydoras (Callichthyidae), ornamental fish endemic to the eastern Amazon (Brazil)

description: Abstract Abstract: This study compared the parasites community in Corydoras ephippifer, Corydoras melanistius, Corydoras amapaensis and Corydoras spilurus from tributaries from the Amapari River in State of Amapá (Brazil). A total of 151 fish of these four ornamental species were examined, of which 66.2% were parasitized by one or more species, and a total of 732 parasites were collected. Corydoras ephippifer (91.2%) and C. spilurus (98.8%) were the most parasitized hosts, while C. amapaensis (9.6%) was the least parasitized. A high similarity (≅ 75%) of parasite communities was found in the host species. Hosts were parasitized by Procamallanus (Spirocamallanus) inopinatus, Camallanus sp. and metacercariae of digeneans. The parasites had an aggregated dispersion pattern, but in C. ephippifer a random dispersion of P. (S.) inopinatus was found. The parasite community was characterized by a low species richness (1-4 parasites per host), low diversity and low evenness, and consisted mainly of endoparasites with high prevalence and low abundance. An important component in the determination of the helminth parasite community composition was the dominance of species that use these fish species as secondary intermediate or paratenic hosts. This was the first study on the parasite community for these four hosts. A checklist of parasite species in wild populations of Corydoras spp. from different localities was also reported here.

title: IMPACT OF VITAMIN D AND CALCIUM DEFICIENCY IN THE BONES OF PATIENTS UNDERGOING BARIATRIC SURGERY: A SYSTEMATIC REVIEW

description: ABSTRACT Introduction: Bariatric surgery is considered the most effective tool in the control and treatment of severe obesity, but patients undergoing this procedure are at increased risk of developing nutritional deficiencies by limiting the intake and absorption of many nutrients. Objective: To assess the impact of vitamin D deficiency and calcium in bone in patients after gastric bypass in Roux-en-Y, pointing directly at the type of administration, doses and effects after surgery. Method: Was conducted a systematic review with articles related to the topic of the last 10 years searched in PubMed (US National Library of Medicine National Institutes of Health, Medline, Lilacs, Scielo and Cochrane using the headings "bariatric surgery", "bone", "obesity", "vitamin D '', "calcium" AND "absorption". Exclusion criteria to research on animals, smokers, pregnant women and patient treated with bisphosphonates. Results: Five articles were included in this review. All refer that bariatric surgery can lead to nutritional deficiencies and poor absorption of fats and fat-soluble vitamins and other micronutrients such as calcium. Conclusion: Patients submitted to RYGB should make use of multivitamins and minerals especially vitamin D and calcium to prevent bone fractures. Monitoring, treatment and control of risk factors are essential to prevent complications after this operation.

title: Cirrhotic cardiomyopathy: the liver affects the heart

description: Cirrhotic cardiomyopathy historically has been confused as alcoholic cardiomyopathy. The key points for diagnosis of cirrhotic cardiomyopathy have been well explained, however this entity was neglected for a long time. Nowadays the diagnosis of this entity has become important because it is a factor that contributes significantly to morbidity-mortality in cirrhotic patients. Characteristics of cirrhotic cardiomyopathy are a hyperdynamic circulatory state, altered diastolic relaxation, impaired contractility, and electrophysiological abnormalities, particularity QT interval prolongation. The pathogenesis includes impaired function of beta-receptors, altered transmembrane currents and overproduction of cardiodepressant factors, such as nitric oxide, cytokines and endogenous cannabinoids. In addition to physical signs of hyperdynamic state and heart failure under stress conditions, the diagnosis can be done with dosage of serum markers, electrocardiography, echocardiography and magnetic resonance. The treatment is mainly supportive, but orthotopic liver transplantation appears to improve this condition although the prognosis of liver transplantation in patients with cirrhotic cardiomyopathy is uncertain.
