1. Bioactive SiO2-K2O-CaO-P2O5 glass-ceramic scaffold prepared using polyurethane foam template
Abstract A glass-ceramic in the SiO2-K2O-CaO-P2O5 quaternary system was prepared by substituting the Na2O component with K2O to avoid Na2Ca2Si3O9 formation upon thermal treatment since this phase decreases apatite formation kinetics on glass material. To form the glass-ceramic, a modified sol-gel method involving solution precipitation, followed by reagents

2. A 120-second stretch improves postural control and plantar pressure: quasi-experimental study
ABSTRACT BACKGROUND: There are no studies on long-term bilateral calf stretching in relation to balance and plantar pressure. OBJECTIVES: To demonstrate that there is better control of posture and pressures after continuous stretching of the posterior calf muscles. DESIGN AND SETTING: Pre and post-intervention study conducted in a private clinic. METHODS

3. Effects of Hyperthyroidism on Contractility and Na+/Ca2+ Exchanger Activity in the Isolated Papillary Muscle of Rats
Abstract Background: Hyperthyroidism (Hy) is an endocrine disorder, in which the thyroid hormones markedly alter the cardiac function. Increased myocardial contractility and cardiac output, improvement in diastolic relaxation, changes in electrical activity, increments in ventricular mass, and arrhythmias have been reported. However, the influences of thyro

4. Treatment of Hepatitis C with Direct-Acting Antivirals does not Induce Significant Arrhythmias
Abstract Background Chronic Hepatitis C (CHC) therapy with direct-acting antivirals (DAAs) has high efficacy and safety, but some cases of bradyarrhythmias have been described. Objective To evaluate heart rhythm disorders during DAA treatments. Methods Forty-eight patients with CHC (mean 61 years of age; 56% males; 73% HCV genotype 1) were evaluated be

5. Associated factors with umbilical arterial pH after cesarean delivery under spinal anesthesia: a retrospective cohort study
Abstract Background: Maximum decrease of blood pressure and number of minutes of hypotension were independently associated with umbilical arterial pH. However, the impact of hypotension considering the duration of it on umbilical arterial pH is unknown. Methods: Pregnant women aged ≥ 20 years who delivered a baby at full-term via a cesarean delivery unde

6. C-Reactive Protein to Albumin Ratio as A Novel Inflammatory-Based Marker for 30-Day Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement
Abstract Objective: We aimed to investigate whether C-reactive protein to albumin ratio (CAR) predicts the early and late mortality in patients undergoing transcatheter aortic valve replacement (TAVR). Methods: This study was retrospectively designed and includes 170 TAVR patients with a mean age of 78.4±7.1 years. Patients were divided into 2 groups as t

7. Prevalence and Predictors of Functional Evacuation Disorder in Patients with Chronic Constipation
Abstract Background Functional evacuation disorder (FED) is the second most common cause of functional constipation (FC) after constipation-predominant irritable bowel syndrome. However, the data on FED is relatively scanty in our region. Hence, the present study was performed to evaluate the demographics of FED and to find out the predictors of FED in pati

10. Environmental effects of leachate extracts from reclaimed asphalt pavement: determination of metals, polycyclic aromatic hydrocarbon and acute toxicity to Daphnia magna
RESUMO Reclaimed Asphalt Pavement (RAP) has a variety of organic and inorganic compounds that can interact with the environment and promote deleterious effects on human health. This study investigated the potential toxicity of RAP through metal determination, polycyclic aromatic hydrocarbon (PAH) analysis and acute toxicity tests with Daphnia magna. Leached

11. Control of leaf anthracnose of peach palm with fungicides: a valid strategy for seedling nurseries, but not for young plantations
ABSTRACT This work aimed to evaluate the efficacy of fungicides for controlling anthracnose (Colletotrichum gloeosporioides) on peach palm (Bactris gasipaesvar.gasipaes) seedlings in nursery beds and in newly planted peach palms in the field. The nursery experiment included two fungicide combinations: [thiophanate-methyl + chlorothalonil (TM + C) and pyraclo
