1. Identification of Synthetic Drugs on Seized Blotter Papers Using ATR-FTIR and PLS-DA: Routine Application in a Forensic Laboratory
Blotter papers seizures containing synthetic drugs have intensified over the last decades. These drugs were originally conceived as “legal” alternatives to traditional illicit drugs, designed to mimic their effects and circumvent control agencies. Reference methods for determining these substances on blotter papers are based on chromatographic techniques

2. Sialendoscopy Training: Presentation of a Realistic Model
Abstract Introduction Several surgical training simulators have been created for residents and young surgeons to gain experience with surgical procedures. Laboratory training is fundamental for acquiring familiarity with the techniques of surgery and skill in handing instruments. Objective The aim of this study is to present a novel simulator for trainin

3. SEPARAÇÃO SÓLIDO-LÍQUIDO: CENTRÍFUGAS E PAPÉIS DE FILTRO
This work describes the fundamentals and evolution of two current solid-liquid separation methods found in the chemical laboratory: the filter paper and the centrifuge. Both methods were developed in the 19th century and are recognized as valuable techniques for industrial and laboratory purposes. However, significant improvements were introduced only fro

5. A complete molecular biology assay for hepatitis C virus detection, quantification and genotyping
Introduction Molecular biology procedures to detect, genotype and quantify hepatitis C virus (HCV) RNA in clinical samples have been extensively described. Routine commercial methods for each specific purpose (detection, quantification and genotyping) are also available, all of which are typically based on polymerase chain reaction (PCR) targeting the HCV 5

6. Experimento utilizando grãos para explorar a calibração em análises químicas
The conventional curriculum of Analytical Chemistry undergraduate courses emphasizes the introduction of techniques, methods and procedures used for instrumental analysis. All these concepts must be integrated into a sound conceptual framework to allow students to make appropriate decisions. Method calibration is one of the most critical parameters that has

7. Animal models of alcohol and drug dependence
Drug addiction has serious health and social consequences. In the last 50 years, a wide range of techniques have been developed to model specific aspects of drug-taking behaviors and have greatly contributed to the understanding of the neurobiological basis of drug abuse and addiction. In the last two decades, new models have been proposed in an attempt to c

8. Laboratory processing and intracytoplasmic sperm injection using epididymal and testicular spermatozoa: what can be done to improve outcomes?
There are two main reasons why sperm may be absent from semen. Obstructive azoospermia is the result of a blockage in the male reproductive tract; in this case, sperm are produced in the testicle but are trapped in the epididymis. Non-obstructive azoospermia is the result of severely impaired or non-existent sperm production. There are three different sperm-

9. Linear dimensional change, compressive strength and detail reproduction in type IV dental stone dried at room temperature and in a microwave oven
The type IV dental stone is widely used for the fabrication of dyes and master casts for fixed and removable partial prostheses. It is typically normal to wait at least 24 hours for the casts to dry prior to beginning the laboratory procedures. The waiting time has been shown to be greatly reduced by using microwave drying. OBJECTIVE: This study evaluated th

10. Furfural - da biomassa ao laboratório de química orgânica
The goal of this manuscript is provide to students of Chemistry and related areas an alternative experiment in which they can obtain a compound and learn to observe and interpret properties and predict organic structure by obtaining furfural from biomass. Furfural is an organic compound, obtained through acid hydrolysis of pentosans, commonly used in the che

11. Establishing a stem cell culture laboratory for clinical trials
Adult stem/progenitor cells are found in different human tissues. An in vitro cell culture is needed for their isolation or for their expansion when they are not available in a sufficient quantity to regenerate damaged organs and tissues. The level of complexity of these new technologies requires adequate facilities, qualified personnel with experience in ce

12. Caracterização molecular de isolados de Giardia spp. provinientes de amostras fecais de origem humana do Hospital Universitário - USP - São Paulo, pela análise de fragmentos do gene codificador da beta-giardina (bg). / Molecullar charaterization of Giardia spp. from human faecal samples of Hospital Universitário USP São Paulo, by analisys of fragments from code gene da beta-giardina (bg).
A giardíase é uma doença entérica de alta prevalência particularmente nos países em desenvolvimento. Diferentes espécies foram descritas em função de seus hospedeiros. A G. duodenalis é a espécie que parasito não só o homem, mas também animais domésticos e silvestres. Recentemente, com a aplicação de técnicas moleculares, foi possível iden
