1. 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

2. Intraoperative frozen section performance for thyroid cancer diagnosis
ABSTRACT Objective: A primary medical relevance of thyroid nodules consists of excluding thyroid cancer, present in approximately 5% of all thyroid nodules. Fine-needle aspiration biopsy (FNAB) has a paramount role in distinguishing benign from malignant thyroid nodules due to its availability and diagnostic performance. Nevertheless, intraoperative frozen

3. On the classification and treatment of outliers in a spatial context: A Bayesian Updating approach
Abstract Checking and treating extreme values is commonplace in modelling workflows. The main methods to manage outliers may be categorized into graphical, Kriging- and simulation-based approaches. While graphical methods usually classify outliers from a global perspective, geostatistical methods evaluate outliers in a local context. Ordinary-Kriging based a

4. Analytical method validation for the identification and quantification of dissolved gold and gold nanoparticles in cosmetics products by single particle inductively coupled plasma mass spectrometry
Nanoparticle (NP) applications have recently gained more space in the development of many products, especially in cosmetology. The aim of the present study was to validate a single particle inductively coupled plasma mass spectrometry technique for the detection and quantification of gold nanoparticles (AuNPs) and gold ions (Au (i)) in different cosmetics cu

5. Editorial Comment: How I do it open distal ureteroureterostomy for ectopic ureters in infants with duplex systems and no vesicoureteral reflux under 6 months of age
ABSTRACT Objectives: Develop and validate a new and simplified score for evaluating the lower urinary tract symptoms in men. Materials and methods: We modified the existing visual prostate symptom score, including changes in the images, sequence, and new alternatives, resulting in a new visual score (LUTS visual score-LUTS-V). For the validation of the new

6. Strategies used to control the costs of underground ventilation in some Brazilian mines
Abstract In an underground mine, the ventilation is responsible for 25% to 50% of its electrical energy consumption. In countries such as South Africa, United States and Canada researchers have started to achieve a significant reduction in energy consumption without neglecting aspects of the quantity and quality of air required for the best performance of th

7. COMPOSTOS QUIMIOTERÁPICOS DE OURO: UMA VISÃO GERAL DOS COMPLEXOS ANTICÂNCER DE Au(I/III) EM RELAÇÃO À ESTRUTURA DO LIGANTE
Gold compounds engage an important place in the field of medicinal chemistry due to their therapeutic properties. Since the last four decades, Au(I) and Au(III) complexes have attracted the attention of researchers due to their anti-tumor proprieties and the different mechanisms of action they display in comparison to conventional anticancer platinum compoun

12. Zinc alpha 2 glycoprotein as an early biomarker of diabetic nephropathy in patients with type 2 diabetes mellitus
Resumo Introdução: Embora a microalbuminúria continue sendo o padrão ouro para a detecção precoce da nefropatia diabética (ND), ela não é um preditor suficientemente preciso do risco de ND. Assim, novos biomarcadores para prever mais precocemente o risco de ND e possivelmente evitar a ocorrência de doença renal terminal estão sendo investigados.
