13. Syndecan-1 as a marker to predict acute kidney injury after isolated coronary artery bypass graft operations
SUMMARY OBJECTIVE: Postoperative acute kidney injury is an important problem that can occur after coronary artery bypass graft operations, and it is important to identify risky patient groups preoperatively. This study aimed to investigate the importance of preoperative syndecan-1 levels in predicting acute kidney injury after elective coronary artery bypas

14. Fetal thymus in growth-restricted fetuses due to placental insufficiency
SUMMARY OBJECTIVE: The aim of this study was to assess fetal thymus size by ultrasound in growth-restricted fetuses due to placental insufficiency and compare to high-risk and low-risk pregnancy fetuses with normal placental function. METHODS: This is a nested case-control study of pregnant women followed up at a university hospital (July 2012 to July 2013

15. Honey of Tetragonisca angustula from Southwestern Bahia: Influence of Seasonality on the Physicochemical Profile and Glioma Cell Inhibitory Effect
This study aims to analyze Tetragonisca angustula honey from southwestern Bahia for its physicochemical characteristics, phenolic compounds and glioma cell inhibitory effect, in samples from different periods of the year, dry (DP) and rainy (RP) period. The analyses showed that samples obtained in the DP and RP are statistically different for the physicochem

16. Relationship between platelet indices and red cell distribution width and short-term mortality in traumatic brain injury with 30-day mortality
SUMMARY OBJECTIVE: This study aimed at investigating whether there is a relationship between 7- or 30-day mortality and mean platelet volume, platelet distribution width, platelet count-to-total lymphocyte count ratio, or red cell distribution width in patients with traumatic brain injury. METHODS: We retrospectively analyzed intensive care unit patients w

17. Comparison of perioperative indicators, treatment efficacy, and postoperative complications between tonsillotomy and tonsillectomy for children with obstructive sleep apnea hypopnea syndrome
SUMMARY OBJECTIVE: This study aimed to compare the perioperative indicators, treatment efficacy, and postoperative complications between tonsillotomy and tonsillectomy for children with obstructive sleep apnea hypopnea syndrome. METHODS: A total of 134 children with obstructive sleep apnea hypopnea syndrome were divided into tonsillotomy group (n=66) and t

18. Colorimetric analysis of dental porcelains: effects of the background color
Abstract This study evaluated how the background (white or gray) affects the color parameter measurements and color difference calculations (∆Eab and ∆E00) of dental ceramics. Disc-shaped feldspathic ceramic specimens were prepared with two shades (enamel and dentin) and stained in red wine (7-day immersion). A spectrophotometer was used to perform color

19. Evaluation of the Current in the Cell Membrane for Numerical Simulations of Electroporation
Abstract This study presents a rigorous numerical analysis of the current in the cell membrane, subjected to a uniform electric field, and its impact in the pore formation. The numerical model considers a single cell composed of uniform membrane and cytoplasm, in a suspension medium. The current in the cell membrane is calculated using two different approach

20. REPLY TO “LINGUISTIC MEANINGS MEET LINGUISTIC FORM”
Abstract Infiltration of a word’s meaning by world-knowledge is argued to be consistent with the semiological principle. While acknowledging variability in what people know about elephants, there is a common core of what everybody knows that we know we can evoke in anybody’s mind; this constitutes the meaning of the word “elephant”. Regarding truth-c

21. The effectiveness of Kangaroo Mother Care in hospitalization period of preterm and low birth weight infants: systematic review and meta-analysis
Abstract Objective: To evaluate the effectiveness of kangaroo mother care (KMC) in reducing the length of hospital stay of preterm and/or low birth weight infants. Source: Cochrane Library, Pubmed, Embase, LILACS, and Scielo. Randomized clinical trials without time or language limit were included. The intervention was the KMC in preterm and/or low birth we

22. A Finite-Difference Time-Domain Formulation for Modeling Air Ionization Breakdown Streamers
Abstract A numerical model based on the finite-difference time-domain (FDTD) method is developed for calculating discharge currents and fields produced due air ionization between two electrodes. Electric conductivity σ of the ionized channel between two electrodes is calculated using non-linear equations, i.e., σ is obtained using functions of time. The fu

24. Impact of Single versus Double Clamp Technique on Blood Lactate Levels and Postoperative Complications in Coronary Artery Bypass Surgery
Abstract Introduction: Cardiopulmonary bypass (CPB) is associated with hyperlactatemia, which leads to adverse clinical outcomes. No study has examined the effect of different clamping techniques on postoperative hyperlactatemia (PHL). Thus, we aimed to evaluate the impact of two different techniques on PHL and the clinical outcomes in patients undergoing i
