title: Development and clinical application of hydrogel formulations containing papain and urea for wound healing

description: Abstract Hydrogels are used for wound treatment, as they may contain one or more active components and protect the wound bed. Papain is one of the active substances that have been used with this purpose, alongside urea. In this paper, carboxypolymethylene hydrogels containing papain (2% and 10% concentrations) and urea (5% concentration) were produced. Physical-chemical stability was performed at 0, 7, 15 and 30 days at 2-8ºC, 25ºC and 40ºC, as well as the rheological aspects and proteolytic activity of papain by gel electrophoresis. Clinical efficacy of the formulations in patients with lower limb ulcers was also evaluated in a prospective, single-center, randomized, double-blind and comparative clinical trial. The results showed 7-day stability for the formulations under 25ºC, in addition to approximately 100% and 15% of protein activity for 10% and 2% papain hydrogel, respectively. The rheological profile was non-Newtonian for the 10% papain hydrogel tested. There were no significant differences regarding the mean time for healing of the lesions, although 10% papain presented a better approach to be used in all types of tissue present in the wound bed.

title: Cooling of porcine semen in an extender supplemented with isoespintanol

description: ABSTRACT: Spermatozoa experience oxidative, osmotic, chemical, and thermal stresses when cooled, which degrade the quality and fertilizing capacity of the cells. Adding antioxidants to the sperm extender mitigates these alterations. This study evaluated the effect of isoespintanol (ISO) on boar semen subjected to cooling. Fifteen ejaculates from five boars (Susscrofadomestica) were extended in Beltsville thawing solution (BTS) supplemented with 0 µM (control), 5 µM (ISO5), 10 µM (ISO10), 15 µM (ISO15), 20 µM (ISO20), 25 µM (ISO25), and 30 µM (ISO30) of ISO, which were then cooled for five days at 16 °C. Sperm kinetics, total motility (TM), and progressive motility (PM) were evaluated every 24 h using an IVOS computer-assisted sperm analysis (CASA) system. On day 1 and day 5 of cooling, a hypoosmotic test, spectrofluorometry, and flow cytometry were performed to evaluate the following: membrane functionality, measured as a function of hypoosmotic swelling (HOS); total antioxidant capacity (TAC); reactive oxygen species (ROS); and mitochondrial membrane potential (Δ¥M). Regression analysis and comparison of means using the Duncan test were performed. The ISO added had a slight impact on sperm motility, as evidenced by a reduction in TM at 24 h of cooling (but not prior) with the addition of 20 µM of ISO. Similarly, no effect of the ISO on the kinetics and functional integrity of the sperm membrane was observed at 96 h of cooling; however, the regression coefficients indicated that the ISO lowered the rate of decrease in sperm motility and the proportion of rapid spermatozoa relative to the concentration of ISO used. The ISO did not affect the TAC of the cooled semen; however, different concentrations of ISO lowered ROS production in the semen after 96 h of cooling. ISO also impacted the Δ¥M of the spermatozoa at 0 h of cooling, increasing the proportion of low Δ¥M cells and decreasing the proportion of high Δ¥M cells. In conclusion, ISO can reduce the loss of quality and oxidative stress occurring in boar semen during cooling and can modulate the mitochondrial activity of sperm.

title: COLLATERALS OF RURAL CREDIT IN BRAZIL: ACCESS, LOAN TERMS, AND DEFAULT

description: ABSTRACT This study investigates the relation between the types of collateral offered in rural loans in Brazil and the access to credit, loan conditions and default rates. We use a novel proprietary database of rural loans granted by one of the largest private banks in Brazil containing more than 110 thousand loan observations. Our results show that the use of fiduciary lien, improves the access to loans for more opaque borrowers (i.e., those with shorter relationship with the bank). This type of collateral gives the bank the ability to seize collateral quicker, reducing loss given default, even if these borrowers are riskier, given that they present higher default rates on average. Our results also show that loan conditions are less restrictive as relationship length increases, and that this effect is more intense among loans collateralized by fiduciary lien.

title: Prognosis Related to Reperfusion Therapy Post-Acute Coronary Syndrome in Secondary Care: Long-Term Survival Analysis in the ERICO Study

description: Abstract Background Relationship between reperfusion therapy post-acute coronary syndrome (ACS) and mortality in secondary care is not well-known. Objectives To evaluate the impact of three therapeutic strategies: (1) exclusive medical therapy, (2) percutaneous coronary intervention (PCI) and (3) coronary artery bypass grafting (CABG) on long-term survival of participants in the Strategy of Registry of Acute Coronary Syndrome (ERICO) study. Methods Survival analyses for all-cause, cardiovascular (CVD) and coronary artery disease (CAD) mortality were performed according to three therapeutic strategies (exclusive medical therapy, PCI or CABG). Cox regression models were used to estimate the hazard ratio (HR) with respective 95% confidence interval (95%CI) from 180 days to four years of follow-up after ACS. Models are presented as crude, age-sex adjusted and further adjusted for previous CAD, ACS subtype, smoking, hypertension, dyslipidemia, left ventricular ejection fraction and according to the number of obstructed (≥ 50%) major coronary arteries. Results Among 800 participants, the lowest crude survival rates were detected among individuals who underwent CABG (all-cause and CVD). CABG was correlated to CAD (HR: 2.19 [95% CI: 1.05-4.55]). However, this risk lost significance in the full model. PCI was associated to lower probability of fatal events during four-year follow-up: all-cause [multivariate HR: 0.42 (95% CI: 0.26-0.70)], CVD [HR: 0.39 (95% CI: 0.20-0.73)] and CAD [multivariate HR: 0.24 (95% CI: 0.09-0.63)] compared to those submitted to exclusive medical therapy. Conclusion In the ERICO study, PCI after ACS was associated to better prognosis, particularly CAD survival.

title: Osseointegration of implants with superhydrophilic surfaces in rats with high serum levels of nicotine

description: Abstract This study aimed to evaluate the effect of nicotine administration on the osseointegration of a superhydrophilic implants surface on rat tibiae. Thirty-two rats were used and divided into 2 groups according to the administration or not of nicotine: HH - Installation of implants with superhydrophilic surfaces in healthy animals; and HN - Installation of implants with superhydrophilic surfaces in animals subjected to nicotine administration. The animals were euthanized 15 and 45 days after implant placement (n = 8). Osseointegration was assessed by means of biomechanical analyses (removal torque), microcomputed tomography (volume of bone around the implants- %BV/TV), and histomorphometry (bone-implant contact -%BIC and the bone area between implant threads -�T). The animals subject to the nicotine administration presented lower removal torque than the control animals at the 45-day period (21.88 ± 2.80 Ncm vs. 17.88 ± 2.10 Ncm). The implants placed in the control rats presented higher %BIC (54.26 ± 6.59% vs. 39.25 ± 4.46%) and �T (50.57 ± 5.28% vs. 32.25 ± 5.24%) than the implants placed in nicotine animals at 15-day period. The nicotine administration reduces the osseointegration at 15 days, however, the superhydrophilic surface equalized the osseointegration in nicotine-exposed animals compared with healthy animals after 45 days of implant placement.

title: Neuroprotective potential of the Amazonian fruits Euterpe oleracea Mart. and Paullinia cupana Kunth

description: Abstract Acai (Euterpe oleracea Mart.) and guarana (Paullinia cupana Kunth) are native species from the Amazon Forest that in folk medicine are used to treat several diseases due to their anti-inflammatory and antioxidant properties. This review brings together findings from different studies on the potential neuroprotective effects of acai and guarana, highlighting the importance of the conservation and sustainable exploitation of the Amazon Forest. A bibliographic survey in the PubMed database retrieved indexed articles written in English that focused on the effects of acai and guarana in in vitro and in vivo models of neurodegenerative diseases. In general, treatment with either acai or guarana decreased neuroinflammation, increased antioxidant responses, ameliorated depression, and protected cells from neurotoxicity mediated by aggregated proteins. The results from these studies suggest that flavonoids, anthocyanins, and carotenoids found in both acai and guarana have therapeutic potential not only for neurodegenerative diseases, but also for depressive disorders. In addition, acai and guarana show beneficial effects in slowing down the physiological aging process. However, toxicity and efficacy studies are still needed to guide the formulation of herbal medicines from acai and guarana.

title: Bibliometric revision regarding the use of survival analysis in seed germination studies

description: ABSTRACT: Studies on seed science are developed for a wide range of purposes, being the statistical analysis of data essential for experimental reliability and evidence. Due to the characteristics of seed data, several statistical methods can be applied, among them the survival analysis stands out, in virtue of allocating censored data and describing phenomena over time. Therefore, this bibliometric study verified the use of survival analysis in studies with seed germination and to examine the applications of survival analysis in original articles from the Web of Science database for the period from 2000 to 2020. For the application of survival analysis, there was a low number of publications related to seed science, with the USA being the country with the highest number of publications mainly to studies in plant ecology and physiology. In general, the researches were most involved to the evaluation of factors influencing dormancy, physiological stresses, dispersion capacity, population differences and habitats of development which affected seed germination. Therefore, the qualitative overview demonstrates that the survival analysis is a statistical tool of great potential regarding the studies in the area.
