title: Basilar artery tortuosity as a predictive factor for the efficacy of heparin adjuvant therapy in unilateral idiopathic sudden sensorineural hearing loss

description: Abstract Introduction Cochlear ischemia is hypothesized as one of the major etiologies of idiopathic sudden sensorineural hearing loss. Therefore, anticoagulant therapies are designed to be beneficial in certain patients with this condition. Objective This study aimed to determine which patients with idiopathic sudden sensorineural hearing loss would benefit from heparin treatment as adjuvant therapy. Methods In total, 134 patients who underwent magnetic resonance imaging for unilateral idiopathic sudden sensorineural hearing loss at a tertiary referral hospital between January 2014 and December 2018 were included in this retrospective study. All patients received Intratympanic steroid injections or heparin therapy plus oral corticosteroids. Radiological parameters of the vertebrobasilar system and clinical data from pre- and post-treatment assessments were analyzed. Results Most patients (71.6%) had a tortuous basilar artery The 65 patients with severe-to-profound idiopathic sudden sensorineural hearing loss showed a significant relationship between idiopathic sudden sensorineural hearing loss laterality and basilar artery displacement to the opposite side (p= 0.036), while the 69 patients with mild-to-moderate idiopathic sudden sensorineural hearing loss did not (p= 0.950). Additionally, the degree of basilar artery tortuosity was significantly associated with the degree of hearing impairment in the severe-to-profound idiopathic sudden sensorineural hearing loss group (p= 0.015). When idiopathic sudden sensorineural hearing loss occurred on the opposite side to basilar artery displacement, the improvement of hearing was significantly greater in patients treated with heparin than in those treated with intratympanic steroids (p= 0.041). Conclusion In a subset of patients with severe-to-profound idiopathic sudden sensorineural hearing loss, basilar artery tortuosity had a significant directional relationship with idiopathic sudden sensorineural hearing loss laterality. In these selected patients, a significant effect of heparin therapy on improving hearing was observed.

title: Productive and physiological performance of jambu genotypes cultivated in hydroponics

description: ABSTRACT Jambu is a condiment herb used in the preparation of typical and herbal dishes in the Amazon Region. The inflorescences, leaves, and stems of the plant are used. In addition, jambu has numerous applications in the cosmetics and food industries due to the presence of the bioactive compound spilanthol. The objective of this study was to evaluate the productive and physiological performance of jambu genotypes of Acmella oleracea, and Acmella ciliata species grown in hydroponics. The experiment used was a completely randomized design with eight treatments and four replicates. The treatments consisted of jambu genotypes (UFR-1, UFR-2, UFR-3, UFR-4, UFR-5, UFR-6, UFR-7 and UFR-8) collected in different locations in the state of Pará. We evaluated the beginning of flowering, length of the main branch, diameter of the main branch, leaf area, shoot fresh mass, inflorescence fresh mass, root fresh mass, total fresh mass, net photosynthetic rate, stomatal conductance, internal CO2 concentration, and instant carboxylation efficiency. The genotypes presented different behaviors about the productive and physiological growth characteristics. The genotypes UFR-1, UFR-2, UFR-3, UFR-4 and UFR-7 exhibited greater precocity of flowering. In general, genotypes of the species A. oleracea presented lower rate of net photosynthesis when compared to those of the species A. ciliata. The genotypes of A. oleracea showed total fresh mass accumulation capacity, in addition to a high potential for inflorescence production. The genotypes UFR-2 and UFR-4 stood out because they presented higher yields of shoots fresh mass and inflorescences, respectively. Therefore, these genotypes should be considered in crop improvement programs.

title: REFLEXIVITY, ROLE CONFLICTS, AND THE MEANING OF ENGLISH SELF PRONOUNS

description: Abstract This study offers an innovative, sign-based analysis of English self pronouns (myself, yourself, herself, etc.). While rejecting the traditional characterization of these forms as reflexive pronouns, the study borrows from the tradition by analyzing these forms as a kind of emphatic pronoun. The forms’ distribution can be explained by positing that they are semantic signals deployed by speakers to meet communicative goals. Speakers choose between self and simple pronouns when the additional meaning of self forms, INSISTENCE ON AN ENTITY(S), will steer hearers in particular interpretive directions. This approach has led to the discovery that reflexive uses of self pronouns are an instantiation of the general tendency to use these forms for unexpected messages, including those in which a single referent is playing more than one role at one time. The presence of such a role conflict accounts not only for reflexive uses, but also for the appearance of self pronouns in picture noun phrases, logophoric contexts, and other previously unexplained exceptions to the structural reflexivity account.

title: Deficiency and Insufficiency of Vitamin D in Women of Childbearing Age: A Systematic Review and Meta-analysis

description: Abstract Objective To estimate the prevalence of inadequate vitamin D level and its associated factors for women of childbearing age in Brazil. Methods A systematic reviewwas conducted (last updatedMay 2020).Meta-analyses were performed using the inverse-variance for fixed models with summary proportion calculation by Freeman-Tukey double arcsine. Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies. Results Our review identified 31 studies, comprising 4,006 participants. All the studies had at least one weakness, mainly due to the use of convenience sampling and small sample size. The overall prevalence of vitamin D deficiency, insufficiency, and both deficiency and insufficiency were 35% (confidence interval, 95%CI: 34-37%), 42% (95%CI: 41-44%), and 72% (95%CI: 71-74%), respectively. Conclusion Although the magnitude of the prevalence of inadequate levels of vitamin D is uncertain, the evidence suggests that presence of vitamin D deficiency or insufficiency in women of reproductive age can cause moderate to severe problems.

title: Rhizophagus clarus controls Meloidogyne javanica and enhances the activity of defense-related enzymes in tomato

description: ABSTRACT Root-knot nematodes (Meloidogyne spp.) cause severe damage to tomato crop. This study aimed to investigate the biocontrol potential of the arbuscular mycorrhizal fungus Rhizophagus clarus compared with that of the fungi Trichoderma harzianum and Pochonia chlamydosporia against Meloidogyne javanica in tomato and assess the activity of defense-related enzymes in mycorrhizal roots. Three experiments were carried out to evaluate mycorrhizal colonization, nematode penetration, development, and reproduction, plant growth, and enzyme activity in mycorrhizal roots. We observed that R. clarus colonization of tomato roots increased with time. Although R. clarus did not prevent nematode penetration or development in roots, it was efficient in reducing total nematode numbers. R. clarus, T. harzianum and P. chlamydosporia treatments reduced nematode reproduction by 56.5, 54.4, and 56.9%, respectively, compared with the control. Moreover, R. clarus increased tomato shoot weight and phenylalanine ammonia-lyase and peroxidase activities.

title: Yield performance and agro-economic efficiency of radish-arugula intercropping under green manuring and planting density

description: ABSTRACT The cultivation of radish with arugula in strip-intercropped systems is growing in semi-arid environments. The great challenge has been to assess whether there is agro-economic efficiency in the intercrops when fertilized with plant biomass of spontaneous species from the Caatinga biome. Thus, the objective of this study was to evaluate the productive and economic viability of radish and arugula strip-intercrops fertilized with Merremia aegyptia and Calotropis procera biomass equitable amounts from the Caatinga biome at different population densities of arugula at two cropping years. The experimental design used was randomized blocks, with the treatments arranged in a 4x4 factorial scheme, with four replicates. The first factor was constituted by four biomass equitable amounts of M. aegyptia and C. procera (20, 35, 50 and 65 t ha-1 on a dry basis), and the second factor by the population densities of arugula plants [40, 60, 80 and 100% of the recommended density for single crop (RDSC)] intercropped with 100% of the radish RDSC. The highest agro-economic advantages of radish and arugula intercropping were obtained for a land equivalent coefficient (LEC) and monetary equivalent ratio (MER) of 0.55 and 1.35, respectively, for M. aegyptia and C. procera biomass amounts of 54.75 and 54.55 t ha-1 added to the soil. The arugula population density of 100% of the RDSC provided the greatest agro-economic efficiency of the intercropped system of radish with arugula with LEC and MER of 0.58 and 1.33, respectively. The use of M. aegyptia and C. procera biomass from the Caatinga biome, proved to be a viable technology for producers who practice the cultivation of radish and arugula in intercropped systems in a semi-arid environment. The concern of the farmer regarding the preservation of natural resources, as well as with the search for a better quality of life, circumvents the possible limitations that the environment may offer in a given intercropping crop. The option by intercropping system can provide to producers viable alternatives to optimize the planted area, in addition to greater productivity and economic stability of activities on the rural property.

title: Electrical conductivity of the nutrient solution for soilless cultivation of kohlrabi

description: ABSTRACT The electrical conductivity of the nutrient solution directly affects production and quality of the plants. We evaluated the electrical conductivity suitable for soilless cultivation of kohlrabi. The experiment was carried out in a completely randomized design, with four replicates and five treatments, composed of different nutrient solution’s conductivities (1.31, 1.71, 2.37, 2.98 and 3.75 dS m-1). We evaluated number of leaves, leaf area, specific leaf area, leaf area ratio, fresh and dry masses of leaves, bulb, roots and total, bulb volume, water content in the bulbs and pH, soluble solids, vitamin C, firmness, titratable acidity and SS/TA ratio of the bulbs. All variables related to growth were affected by the nutrient solutions, showing the highest values with the use of the nutrient solutions with EC close to 2.0 dS m-1. Considering the commercial part of the plant, the most developed bulbs were obtained with EC of 1.96 dS m-1, being 49.9 g and 41.15 cm3 per bulb. On the other hand, except for pH, the other variables responded to the increase of EC. Higher values for pulp firmness and titratable acidity occurred with EC close to 2.0 dS m-1, whereas the other variables showed higher values using a more concentrated nutrient solution.
