1. Quais os achados clínicos e tratamento devem ser indicados ao paciente vítima de acidente por serpente peçonhenta e não peçonhenta?
A maioria dos acidentes, seja por uma serpente venenosa ou não, leva a algum tipo de efeito local. Uma vez que a identificação da serpente causadora do acidente nem sempre é possível de ser feita, o diagnóstico do tipo de envenenamento é baseado em critérios clínicos (sinais e sintomas) e epidemiológicos.

2. It’s not always postdural puncture headache: a case report and note to the astute anesthesiologist
Abstract Dural puncture is either diagnosed by unexpectedly profound response to medication test dose or development of a postpartum postural headache. Epidural blood patch is the gold standard for treatment of PDPH when conservative management fails. However, postpartum headaches can be resistant to multiple epidural blood patches. In such cases, preexistin

3. A comparison between ultrasonography and single-phase computed tomography for preoperative assessment of solid abdominal tumors in children
Abstract Objective: This study aimed to estimate the performance of single-phase-enhanced computed tomography and ultrasonography examinations in the preoperative evaluation of solid abdominal tumors and their relationship with relevant adjacent structures in children. Methods: This retrospective study included 50 pediatric patients with malignant solid ab

4. Early versus late sphenopalatine ganglion block with ropivacaine in postdural puncture headache: an observational study
Abstract Background Postdural puncture headache (PDPH) is a common complication of neuraxial techniques which delays patients’ discharge. Sphenopalatine ganglion block (SPGB) is a safe bedside technique with comparable efficacy to Epidural Blood Patch, the gold-standard treatment. There is no evidence on the ideal timing for SPGB performance. We aimed to

5. Atomic Absorption Spectrometry as an Alternative to Determine the Presence of Gold Nanoparticles on or in Silica Matrix
Two different gold-silica-based nanomaterials were prepared: (i) silica-supported gold nanoparticles (AuNP/SiO2); and (ii) gold-silica core-shell nanoparticles (AuNP@SiO2). Three strategies for sample treatment (S), consisting in acid treatments, were employed: (S1) HNO3; (S2) HNO3 + HCl; and (S3) HF + HNO3 + HCl, applying microwave oven digestion for S2 and

7. Prospects for Developing Low-Cost Optical Fiber Sensors for Liquid-Liquid Interface Detection
Abstract This work examines the prospects of a low-cost retroreflection optical sensor system for detection of the interface between two immiscible liquids, for applications in oil separation tanks. The sensor in its simplest configuration comprises a bare fiber optic tip, cleaved at an angle of 90º relative to the longitudinal fiber axis. The device tested

8. Diagnostic accuracy of lung ultrasound for transient tachypnea: a meta-analysis
Abstract Objective: The objective of this meta-analysis was to study the diagnostic value of lung ultrasound (LUS) for transient tachypnea of the newborn (TTN). Methods: Embase, Cochrane Library, PubMed, Web of Science, and Google Scholar were searched, and the last search date was October 31, 2020. Studies on the diagnostic accuracy of pulmonary ultrasoun

9. Design and Simulation of Broadband Horn Nanoantennas for Nanophotonic Applications
Abstract Optical plasmonic nanoantennas have proven useful in nanoplasmonic applications, paving the way for more efficient wireless optical communications. In this work, we propose a parametric study of a plasmonic horn nanoantenna in flat H sectorial format and beveled horn, both designed to radiate in the three wavelengths of optical communications: [850

10. A Colorimetric and Fluorescent Dual-Signal Sensor for Detecting Lipase Activity Based on Inner Filter Effect
We developed a colorimetric and fluorescence dual-signal sensor for detecting lipase activity based on methyl thioglycolate (MT) functionalized gold nanoparticles (MT-AuNPs) and CdS quantum dots (CdS QDs). It is the first time that was developed a dual-signal sensing strategy for lipase activity based on the inner-filter effect (IFE) between MT-AuNPs and CdS

11. Analysis of antepartum cardiotocography based on S/k proportions and probability in 20 minutes
Resumo Objetivos: aunque se ha logrado reducir considerablemente la mortalidad y asfixia perinatal en neonatos, aún hay deficiencias en los métodos de tamizaje y diagnóstico del bienestar fetal intraparto que detecten sus alteraciones tempranas. Por lo anterior, el propósito de esta investigación fue aplicar una metodología basada en la probabilidad y

12. Unplanned dilution back analysis in an underground mine using numerical models
Abstract In underground mines, stability problems can cause unplanned dilution, increasing the costs of mining operations, such as loading, transport, crushing and grinding. This is usually dealt with by simply increasing investments with support. However, the design geometry of stopes and drifts also has a great effect on a stope’s stability. The use of e
