Diclofenac (DCF) is an environmentally persistent, nonsteroidal anti-inflammatory drug (NSAID) with thyroid disrupting properties. Electrochemical advanced oxidation processes (eAOPs) can efficiently remove NSAIDs from wastewater. However, eAOPs can generate transformation products (TPs) with unknown chemical and biological characteristics.

Recently, two-dimensional liquid chromatography (2D-LC) has become a popular approach to analyze complex samples. This is partly due to the introduction of commercial 2D-LC systems. In the past, 2D-LC was carried out on in-house developed setups, typically consisting of several switching valves and sample loops as the interface between the two dimensions.

Conventional water treatment methods are not efficient in eliminating endocrine disrupting compounds (EDCs) in wastewater. Electrochemical Advanced Oxidation Processes (eAOPs) offer a promising alternative, as they electro-generate highly reactive species that oxidize EDCs. However, these processes produce a wide spectrum of transformation products (TPs) with unknown chemical and biological properties.

Population surveillance in COVID-19 Pandemic is crucial to follow up the pace of disease and its related immunological status. Here we present a cross-sectional study done in Maricá, a seaside town close to the city of Rio de Janeiro, Brazil. Three rounds of study sampling, enrolling a total of 1134 subjects, were performed during May to August 2021.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has posed challenges to healthcare professionals, who needed to quickly adjust impacts on their work processes. Primary health care has become key to fighting the pandemic, as most mild cases seek primary care services as their point of first contact.

Objectives: To ascertain the knowledge, attitudes, and practices of health professionals working in primary health care in Brazil early in the COVID-19 pandemic.

The aim of the study was to evaluate the addition of increasing cottonseed cake contents in the diet. The diets were composed of corn silage (500 g kg) and concentrate feed (500 g kg) on a dry matter (DM) basis. The treatments consisted of the substitution of 0, 140, 280, and 420 g kg soybean meal to cottonseed cake in the DM of concentrate feed.

Purpose: To reduce false-negative rates (FNR) in sentinel lymph node biopsy (SLNB) of clinically positive (cN+) axilla in patients undergoing neoadjuvant chemotherapy (NAC). The removal of three or more lymph nodes with dual-tracer mapping including a radioisotope was used. However, in the Brazilian Unified Health System, the radioisotope tracer is not feasible in some hospitals.

Salmonella enterica serovar Enteritidis is frequently isolated from animal-source foods associated with human salmonellosis outbreaks. This serovar was spread to animal (mainly poultry) farms worldwide in the 1980s, and it is still detected in foods produced in many countries, including Brazil. The present study reports a retrospective genome-wide comparison of S.

Background: The impact of rapid on-site evaluation (ROSE) on thyroid aspirates has been a matter of extensive debate. In the current study, the authors reviewed all thyroid fine-needle aspiration biopsies (FNABs) performed in their service in recent years to evaluate the impact of ROSE on final adequacy and diagnostic rates.

Methods: All ultrasound-guided FNABs of the thyroid performed between July 2015 and July 2017 were included retrospectively.

Introduction: Nontyphoidal Salmonella serotypes are the main cause of human food-borne infection, including several hospitalization cases in the developing countries.

Aim: To detect the main serotypes and to characterize the antibiotic resistance of human non-enteric and enteric nontyphoidal Salmonella from clinical isolates in Brazil.

Methods: Salmonella serotypes were identified by microbiological and molecular methods.

Baclofen, a γ-amino-butyric acid type-B receptor agonist with exponentially increased use at high-dose to facilitate abstinence in chronic alcoholics, is responsible for increasing poisonings. Tolerance and withdrawal syndromes have been reported during prolonged treatment but their contribution to the variability of baclofen-induced neurotoxicity in overdose is unknown. We studied baclofen-induced effects on rat sedation, temperature, and ventilation and modeled baclofen pharmacokinetics and effect/concentration relationships aiming to investigate the consequences of repeated baclofen pretreatment and to characterize withdrawal syndrome.

A new method for the quantitative analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS) of five tyrosine kinase inhibitors (afatinib, crizotinib, osimertinib, erlotinib and nintedanib) used in the treatment of non-small cell lung cancer (NSCLC) was developed and validated in human plasma. Separation was performed on an Accucore C18 (2.1 × 50 mm; 2.

Stability studies of the pharmaceutically important compound finasteride were conducted in order to evaluate decomposition of the drug under forced degradation conditions. A simple stability-indicating liquid chromatography method was developed and validated for the evaluation of finasteride and degradation products formed in pharmaceutical preparations and the raw material. Isocratic LC separation was achieved on a C18 column using a mobile phase of o-phosphoric acid (0.

As important as perceiving pain is the ability to modulate this perception in some contextual salient situations. The periaqueductal gray (PAG) is perhaps the most important site of endogenous pain modulation; however, little is known about dopaminergic mechanisms underlying PAG-mediated antinociception. In this study, we used a pharmacological approach to evaluate this subject.

Background: Better knowledge of opioid pharmacology after Roux-en-Y gastric bypass (RYGB) is required for optimizing their use in this growing population.

Objective: The aim of this case-controlled pharmacokinetic (PK) study was to compare morphine and its glucuronidated metabolites (morphine-3-glucuronide and morphine-6-glucuronide) plasma PKs between patients with RYGB and their controls.

Settings: University hospital, Lariboisière Hospital, Paris.

Purpose: To investigate allometric relationships among body mass (BM), muzzle-tail length (MTL), and tibia length (TL) in Wistar rats and establish their growth rate change parameters.

Methods: Eighteen male and 18 female Wistar rats were studied from the 3rd to the 21st week of age. BM, MTL, and TL were measured daily, and relative growth was compared using allometry.

Background/aims: Our aim was to investigate a geographical cluster of Huntington's disease (HD) in Ervalia, a Brazilian town of Minas Gerais state (MG). Therefore, we calculated the minimum prevalence of HD in Ervalia, known to have many HD affected families. We also determined the genetic profile of the polymorphic CAG region of the HTT gene in 32 subjects of these affected families.

Background: Hypertrophic cardiomyopathy (HC) is the most prevalent genetic cardiac disease caused by a mutation in sarcomeres, Z-disks, or calcium-handling genes and is characterized by unexplained left ventricular hypertrophy. The aim of this study was to determine the genetic profile of Brazilian patients with HC and correlate the genotype with the phenotype.

Methods: We included 268 index patients from São Paulo city and 3 other cities in Brazil and extracted their DNA from whole blood.
