title: Effect of miR-134 against myocardial hypoxia/reoxygenation injury by directly targeting NOS3 and regulating PI3K/Akt pathway

description: Abstract Purpose To reveal the function of miR-134 in myocardial ischemia. Methods Real-time PCR and western blotting were performed to measure the expression of miR-134, nitric oxide synthase 3 (NOS3) and apoptotic-associated proteins. Lactic dehydrogenase (LDH) assay, cell counting kit-8 (CCK-8), Hoechst 33342/PI double staining and flow cytometry assay were implemented in H9c2 cells, respectively. MiR-134 mimic/inhibitor was used to regulate miR-134 expression. Bioinformatic analysis and luciferase reporter assay were utilized to identify the interrelation between miR-134 and NOS3. Rescue experiments exhibited the role of NOS3. The involvement of PI3K/AKT was assessed by western blot analysis. Results MiR-134 was high regulated in the myocardial ischemia model, and miR-134 mimic/inhibitor transfection accelerated/impaired the speed of cell apoptosis and attenuated/exerted the cell proliferative prosperity induced by H/R regulating active status of PI3K/AKT signaling. LDH activity was also changed due to the different treatments. Moreover, miR-134 could target NOS3 directly and simultaneously attenuated the expression of NOS3. Co-transfection miR-134 inhibitor and pcDNA3.1-NOS3 highlighted the inhibitory effects of miR-134 on myocardial H/R injury. Conclusion This present work puts insights into the crucial effects of the miR-134/NOS3 axis in myocardial H/R injury, delivering a potential therapeutic technology in future.

title: The White Striping myopathy in different broiler strains and its influence on composition and meat quality

description: ABSTRACT The incidence of the White Striping (WS) myopathy in three male broiler strains and its consequences on the chemical composition and physical quality of the meat was evaluated. A completely randomized design (DIC) with three treatments (strains A, B and C) and five replicates of 300 breasts each were used to determine the incidence rates of the different degrees of WS myopathy (normal, moderate and severe) in each strain. For the chemical and physical variables, a 3 X 3 factorial scheme was used (three strains X three WS levels), with 15 replicates. The data were submitted to ANOVA and in cases of significant differences the Tukey test (P&lt; 0.05) was used.The A strain chickens presented 84.81% of breasts classified as normal and 9.91% of breasts classified as moderate, respectively higher and lower values than in the other two strains. Breasts classified with severe WS myopathy were heavier and had higher percentages of lipids and moisture, and lower concentration of crude protein. However, the concentrations of total, soluble and insoluble collagen had interaction effects between lineage and WS level in the fillets, and therefore, the same behavior was not observed in the samples of the different strains.

title: Biomechanical comparison of CRIF and reconstruction plate for stabilization of distal femur fractures in dogs

description: ABSTRACT This study aims to compare the biomechanical properties, through compression eccentric test, of the resistance of the 5.0mm Clamp and Rod Internal Fixation Implants (CRIF) and 3.5mm reconstruction plate in fixing dog femur distal fracture. It was used 22 femurs from 11 dog cadavers with age between 2 and 7 years old and body weight between 20 and 40kg, subdivided into two groups, called CRIF Group (CG - 11 femurs) and plate group (PG - 11 femurs). A distal fracture in the specimens with a gap of 0.5cm osteotomy, was simulated to perform the test, performed by the oscillating saw, just proximal to the beginning of the trochlea. The implants were fixed by the standards AO / SIF, laterally to the femur, using three distal screws and five proximal to the fracture site. PMI computer program was used to calculate the maximum point of resistance before failure and evaluated the variables maximum strength, real maximum deformation, stiffness, intermediate strength and real intermediate deformation. No statistically significant differences were found between the GC and GP as the variables evaluated, suggesting that both implants are good fixation options for such fractures.

title: Neuropathic pain and prognosis of a dog submitted to limb amputation after diagnosis of soft tissue sarcoma - case report

description: ABSTRACT Neuropathic pain occurs when there is a lesion or a dysfunction of the nervous system. Humans and veterinary patients may develop neuropathic pain, but in veterinary it is not often reported probably because of its mistaken diagnosis. A canine patient was admitted to the Veterinary Hospital of UNESP-Jaboticabal-SP, Brazil with a nodule on the left thoracic limb. The nodule was surgically removed, and histopathological analysis demonstrated the tumor was a soft tissue sarcoma (STS) and the margins were not clean. Based on the patient’s health condition and the lack of suitable equipment, the next procedure was limb amputation. The patient received analgesic medication in the post-surgery period; nevertheless, clinical signs of neuropathic pain were present, such as compulsive licking and other behavioral disorders. Medications were administered for forty days, but clinical signs ceased only when replaced with a tryciclic antidepressant drug, Amitriptyline. Therapeutic management of the patient in this report can be considered effective, since five years after the end of the treatment there was no recurrence or presence of metastasis.

title: Update of the diagnostic criteria of brain death: application and training of physicians

description: ABSTRACT Objective: To evaluate the medical knowledge regarding the application of the diagnostic criteria for brain death and to correlate it with training parameters for this diagnosis according to Federal Council of Medicine resolution 2,173 of 2017. Method: We interviewed 174 physicians with experience with comatose patients. A structured questionnaire adapted from previous studies was used. The associations of the variables were tested using the chi-square test for independence. A multivariate logistic model was fitted for associations with p values ≤ 0.20. Results: Among the interviewees, 40% had been working for more than 1 year in intensive care, and 23% had initiated ten or more brain death protocols complying with the new resolution. Forty-five percent of the interviewees reported having difficulty following the criteria, 94% acknowledged the need for complementary tests for diagnosis, and 8% of them reported the existence of incorrect tests. The difficulty with these criteria decreased with an increase in the number of years of medical training (OR = 0.487; p = 0.045; 95%CI 0.241 - 0.983) and with a higher number of initiated brain death protocols (OR = 0.223; p = 0.0001; 95%CI 0.117 - 0.424). Conclusions: Difficulties in the application of brain death criteria were identified by a significant portion of the sample. However, among other factors, more years of training and a greater number of initiated brain death protocols were associated with greater ease in the application of brain death criteria according to the guidelines provided in Resolution 2,173 of the Federal Council of Medicine.

title: Aortic valve endocarditis due to Bartonella clarridgeiae in a dog in Brazil

description: Abstract We report the first documented case of endocarditis associated with Bartonella clarridgeiae in a dog in Latin America. Infective vegetative valvular aortic endocarditis was diagnosed in a 10-year-old male mixed breed dog. The dog presented grade V/VI systolic and diastolic murmur, hyperthermia, and progressive weight loss. Cardiomegaly and presence of diffuse alveolar pattern in the lung fields were observed in the thorax radiography evaluation. Irregular and hyperechogenic structures adhered to the aortic leaflets, causing obstruction of the left ventricular outflow tract and severe aortic insufficiency, were observed in the echocardiography evaluation. A vegetative, whitish, hardened structure measuring 1.0 cm in diameter was observed in aortic semilunar valve at necropsy. Based on a combination of pre-enrichment insect-based medium liquid culture, quantitative real-time and conventional PCR assays based on nuoG and gltA genes, respectively, followed by sequencing and phylogenetic inferences, B. clarridgeiae DNA was detected in the patient’s aortic valve lesions. Clinical, echocardiographic, anatomopathologic and molecular features supported the diagnosis of severe aortic vegetative endocarditis possibly caused by B. clarridgeiae in a dog in Brazil.

title: Autonomic responses of premature newborns to body position and environmental noise in the neonatal intensive care unit

description: ABSTRACT Objective: Evaluate the physiological and autonomic nervous system responses of premature newborns to body position and noise in the neonatal intensive care unit. Methods: A quasi-experimental study. The autonomic nervous system of newborns was evaluated based on heart rate variability when the newborns were exposed to environmental noise and placed in different positions: supine without support, supine with manual restraint and prone. Results: Fifty premature newborns were evaluated (gestational age: 32.6 ± 2.3 weeks; weight: 1816 ± 493g; and Brazelton sleep/awake level: 3 to 4). A positive correlation was found between environmental noise and sympathetic activity (R = 0.27, p = 0.04). The mean environmental noise was 53 ± 14dB. The heart rate was higher in the supine position than in the manual restraint and prone positions (148.7 ± 21.6, 141.9 ± 16 and 144 ± 13, respectively) (p = 0.001). Sympathetic activity, represented by a low frequency index, was higher in the supine position (p &lt; 0.05) than in the other positions, and parasympathetic activity (high frequency, root mean square of the sum of differences between normal adjacent mean R-R interval and percentage of adjacent iRR that differed by more than 50ms) was higher in the prone position (p &lt; 0.05) than in the other positions. The complexity of the autonomic adjustments (approximate entropy and sample entropy) was lower in the supine position than in the other positions. Conclusion: The prone position and manual restraint position increased both parasympathetic activity and the complexity of autonomic adjustments in comparison to the supine position, even in the presence of higher environmental noise than the recommended level, which tends to increase sympathetic activity.

title: Parasitological and histological aspects of Holochilus sciureus naturally infected by Schistosoma mansoni

description: Abstract Schistosomiasis is a neglected disease that affects millions of people around the world, being common in the state of Maranhão. A total of 225 rodents of the Holochilus sciureus species from the Western Lowland Maranhão were studied, of which 144 animals (64%) exhibited Schistosoma eggs in their feces samples. Macroscopic lesions characterized as well-defined whitish areas on the liver and spleen surfaces were observed. Histopathological examination revealed multifocal granulomas in the esophagus, liver, spleen, pancreas and duodenum, with structures compatible with Schistosoma mansoni eggs, as well as severe hepatic micro-vacuolar degeneration, multifocal and coalescent, with proliferation of random bile ducts and associated epithelial hyperplasia to areas of fibrosis. Adult forms of the parasite were observed in the blood vessels of the portal space. The lungs exhibited moderate and diffuse interstitial pneumonia with intralesional S. mansoni eggs. In the kidneys, hyaline cylinders were observed in the pelvis and diffuse hemorrhage. In conclusion, H. sciureus displays a pathological picture similar to human being. This rodent plays a role as sentinel in Baixada Maranhense.

title: An analysis of the services inflation persistence puzzle in Brazil

description: Abstract This article analyzes the so-called Services Inflation Persistence Puzzle in Brazil, for the period ranging from August 1999 to February 2017. As a benchmark, we also analyze the Brazilian Consumer Inflation (IPCA), non-durable, semi-durable and durable goods, as well as some items disaggregated from the basket of services. Structural break tests and ARFIMA models are used. Results show that, initially, services inflation persistence is higher than that found in goods inflation and IPCA. However, after structural breaks are accounted for, services inflation seems to be anti-persistent and stationary, indicating the existence of the Services Inflation Persistence Puzzle in Brazil. The same behavior applies to the main components of the service basket.

title: Respiratory distress syndrome: influence of management on the hemodynamic status of ≤ 32-week preterm infants in the first 24 hours of life

description: ABSTRACT Objective: To investigate the influence of respiratory distress syndrome management on clinical and echocardiographic parameters used for hemodynamic evaluation in ≤ 32- week newborns. Methods: Thirty-three ≤ 32-week newborns were prospectively evaluated and subjected to invasive mechanical ventilation. The need for exogenous surfactant and clinical and echocardiographic parameters in the first 24 hours of life was detailed in this group of patients. Results: The mean airway pressure was significantly higher in newborn infants who required inotropes [10.8 (8.8 - 23) cmH2O versus 9 (6.2 - 12) cmH2O; p = 0.04]. A negative correlation was found between the mean airway pressure and velocity-time integral of the pulmonary artery (r = -0.39; p = 0.026), right ventricular output (r = -0.43; p = 0.017) and measurements of the tricuspid annular plane excursion (r = -0.37; p = 0.036). A negative correlation was found between the number of doses of exogenous surfactant and the right ventricular output (r = -0.39; p = 0.028) and pulmonary artery velocity-time integral (r = -0.35; p = 0.043). Conclusion: In ≤ 32-week newborns under invasive mechanical ventilation, increases in the mean airway pressure and number of surfactant doses are correlated with the worsening of early cardiac function. Therefore, more aggressive management of respiratory distress syndrome may contribute to the hemodynamic instability of these patients.
