title: Pharmacological blockade of protease-Activated Receptor 2 improves airway remodeling and lung inflammation in experimental allergic asthma

description: Abstract Protease-activated receptors (PARs) are metabotropic G-protein-coupled receptors that are activated via proteolytic cleavage of a specific sequence of amino acids in their N-terminal region. PAR2 has been implicated in mediating allergic airway inflammation. This study aims to study the effect of PAR2 antagonist ENMD1068in lung inflammation and airway remodeling in experimental asthma. Allergic lung inflammation was induced in sensitized BALB/c mice through intranasal instillations of ovalbumin (OVA), and mice were pretreated with ENMD1068 1 hour before each OVA challenge. Bronchoalveolar lavage fluid (BALF) was collected, and the lungs were removed at different time intervals after OVA challenge to analyze inflammation, airway remodeling and airway hyperresponsiveness. Ovalbumin promoted leukocyte infiltration into BALF in a PAR2-dependent manner. ENMD1068 impaired eosinophil peroxidase (EPO) and myeloperoxidase (MPO) activity in the lung parenchyma into BALF and reduced the loss of dynamic pulmonary compliance, lung resistance in response to methacholine, mucus production, collagen deposition and chemokine (C-C motif) ligand 5 expression compared to those in OVA-challenged mice. We propose that proteases released after an allergen challenge may be crucial to the development of allergic asthma in mice, and PAR2 blockade may be useful as a new pharmacological approach for the treatment of airway allergic diseases.

title: Acute kidney injury outcomes in covid-19 patients: systematic review and meta-analysis

description: Abstract Background: Acute kidney injury (AKI) is a frequent complication of coronavirus-19 disease (COVID-19). Therefore, we decided to perform a systematic review and meta-analysis with data from the literature to relate the development of COVID-19 associated-AKI with comorbidities, medications, and the impact of mechanical ventilation. Methods: We performed a systematic review using the Newcastle-Ottawa scale and a meta-analysis using the R program. Relevant studies were searched in the PubMed, Medline, and SciELO electronic databases. Search filters were used to include reports after 2020 and cohort studies. Results: In total, 1166 articles were identified and 55 English-written articles were included based on the risk of bias. Of all COVID-19-hospitalized patients presenting with AKI (n = 18029) classified as Kidney Disease Improving Global Outcomes stage 1 to 3, approximately 18% required mechanical ventilation and 39.2 % died. Around 11.3% of the patients required kidney replacement therapy (KRT) and of these, 1093 died and 321 required continuous KRT. Death is more frequent in individuals with AKI [OR 6.03, 95%CI: 5.73-6.74; p&lt;0.01]. Finally, mechanical ventilation is an aggravating factor in the clinical conditions studied [OR 11.01, 95%CI: 10.29-11.77; p&lt;0.01]. Conclusion: Current literature indicates AKI as an important complication in COVID-19. In this context, we observed that comorbidities, such as chronic kidney disease and heart failure, were more related to the development of AKI. In addition, mechanical ventilation was seen as an aggravating factor in this scenario.

title: Persistence of left superior vena cava: a rare cause of hemodialysis tunneled catheter malposition

description: Abstract Hemodialysis central venous catheter (CVC) insertion can be complicated in patients with anomalous vessel anatomy. In such cases detailed knowledge of thoracic vessel anatomy is necessary to identify the exact location of the catheter. Central venous placement under ultrasound control has signiﬁcantly reduced the complications associated with blind puncture and allows an appropriate puncture of the desired vessel, but the CVC can still get misplaced if it follows an anomalous route. Herein, we report a case of dialysis catheter placed into a left sided superior vena cava, only diagnosed after CT scan study.

title: Use of rabbit manure in lettuce culture: an alternative option

description: ABSTRACT Organic fertilization favors the physical and chemical attributes improvement of the soil and promotes the use of waste that would be discarded in the environment. This study aimed to identify the appropriate levels of rabbit manure compost (RMC) from rabbit farming in the production of substrates for lettuce. The experiment was implanted in plastic pots using 5 treatments: 0%, 25%, 50%, 75% and 100% of RMC mixed with commercial substrate, in a completely randomized design with 10 replications. The analyzed variables were number of leaves per plant, shoot green matter, root green matter, shoot dry matter and root dry matter. There was an increase in number of leaves with the increase of the RMC doses incorporated into the substrate, up to the dose of 59.46%. The shoot green matter had its best response on 61.42% of RMC. In both variables there was a decline afterwards. The root green matter started with an increase up to the dose of 36.14% of RMC, followed by a decline, and another increase, not reaching the same values obtained at the beginning of the curve. An increase was observed in the shoot dry matter as the amount of RMC increased, up to the limit of 45.09%, and then declined. The root green matter showed an increase until approximately 25% of RMC, stabilizing on 75% of the compost. In general, values close to 60% of RMC mixed with the substrate presented the best results. We can conclude that the RMC can be used to promote a greater number of leaves, which are the economically viable parts of lettuce culture.

title: Aging-associated prostate smooth muscle hypercontractility in rats

description: Abstract Benign prostatic hyperplasia (BPH) is a multifactorial disease, highly associated with aging and characterized by increased prostate smooth muscle (PSM) contractility. Animal models have been employed to explore the aging-associated PSM hypercontractility; however, studies have focused in old animals, neglecting the initial alterations in early ages. The determination of prostatic dysfunctions onset is crucial to understand the BPH pathophysiology and to propose new BPH treatments. Considering that PSM contractility in 10-month-old rats has already been explored, the aim of the present study was to characterize the PSM contractility in younger rats. Male Wistar control (3.5-month-old), 6- and 8-month-old rats were used. Concentration-response curves to phenylephrine and electrical-field stimulation (EFS) were conducted in prostate from all groups. For the first time, we showed that 6- and 8-month-old rats exhibit PSM hypercontractility. The increased prostate contractility to phenylephrine starts around at 6-month-old, worsening during the aging. The 8-month-old rats exhibited hypercontractility to phenylephrine and EFS compared to the control and 6-month-old groups. Reduced phenylephrine potency was observed in 8-month-old rats, indicating an increased age-dependent prostate sensibility to this agonist. Collectively, our findings support the use of 6- and 8-month-old aged rats as new models to explore prostate hypercontractility in BPH.

title: Enhancement of dissolution rate of racecadotril by liquisolid compact technology

description: Abstract The current investigation was used to improve the rate of dissolution of an anti-diarrheal drug i.e., racecadotril (RT) at low pH conditions (i.e., in the stomach) by reducing the water secretion and electrolyte in to the intestine by liquisolid tablets. Different formulations (liquisolid) were prepared using Avicel PH 102 as a carrier. Aerosil 200 as a coating material and sodium starch glycolate used as a disintegrant. Polyethylene glycol 200 was used as a non-volatile vehicle to dissolve the drug. FTIR, DSC, XRD and dissolution studies were conducted to characterise liquisolid tablets. Characterisation studies indicated that no interactions between carrier and drug. Solid state characterization had shown a reduction in crystallinity that further supports increment in solubility and dissolution. The optimised formulation showed a significant increase in dissolution i.e., 99.54±0.62% in 30 min compared to directly compressible tablets (38.47±0.26%). The % dissolution efficiency of racecadotril liquisolid tablets 76.86% compared to marketed tablet (27.56%) and conventional direct compression tablet (17.11%). Significant reduction in mean dissolution time of racecadotril from liquisolid tablets (6.84 min) compared to direct compression tablet (44.57 min), indicating faster release of drug and faster onset of action. Formulation of liquisolid tablets could enhance solubility, dissolution and bioavailability of racecadotril.

title: Genotyping and phenotyping of grape tomato hybrids aiming at possible genitors for breeding program

description: ABSTRACT Grape and cherry mini tomatoes have been conquering Brazilian consumers due to their sweet taste, practicality of consumption, and versatility in culinary use. Therefore, the present work aimed to characterize ten grape tomato hybrids based on genetic diversity and physical and biochemical traits to provide information for the development of new genotypes focused on the appearance and enrichment of nutritional factors. The evaluated hybrids were Aiko, BRSIG, BRS Zamir, Carolina, Dolcetto, Dulce, Guaraci, Santa West, SCI-023 and Sweet Heaven. The experiment was conducted in 2019 in a greenhouse at the State University of Londrina, using a completely randomized design with four replications and six plants in each replication. The plants were grown following the practices recommended for cultivating tomatoes. The physical and biochemical characterization data were subjected to analysis of variance by the F test (p&lt;0.05) and Scott & Knott means cluster test (p&lt;0.05), and the molecular characterization data were subjected to analysis of principal coordinates (PCoA) and Bayesian clustering. Aiko presented the highest fruit mass and size as opposed to that observed on SCI-023, while BRSIG was the firmest fruit with the largest pericarp thickness. SCI-023, Dolcetto, and Sweet Heaven had higher sugar content. The soluble solids content ranged from 6.04 to 9.66 °Brix among the genotypes. Hybrids SCI-023, BRSIG, Sweet Heaven, BRS Zamir, and Dulce had the highest antioxidant activity levels. In the phenotypic characterization two groups were formed. The genotypic characterization showed seven groups in which high genetic similarity was verified among BRS Zamir, SCI-023, and Guaraci, as well as between Carolina and Dulce. The greatest dissimilarity was observed between Sweet Heaven and BRSIG. Both characterizations were useful to evaluate the aptitude of these genotypes as outstanding genitors for breeding programs for the Brazilian market.
