1. Quantification of cell-free circulating mitochondrial DNA copy number variation in hepatocellular carcinoma
SUMMARY OBJECTIVE: Hepatocellular carcinoma is the most common primary malignant liver tumor. Mitochondrial DNA copy number has been shown to be associated with various malignancies. However, there has not been any study on the absolute quantification of mtDNA copy number in hepatocellular carcinoma. The aim of this study was to develop a new method for abs

4. Protein-species quantitative venomics: looking through a crystal ball
Abstract In this paper we discuss recent significant developments in the field of venom research, specifically the emergence of top-down proteomic applications that allow achieving compositional resolution at the level of the protein species present in the venom, and the absolute quantification of the venom proteins (the term “protein species” is used he

5. Diagnosis of human herpes virus 1 and 2 (HHV-1 and HHV-2): use of a synthetic standard curve for absolute quantification by real time polymerase chain reaction
The use of quantitative real time polymerase chain reaction (qPCR) for herpesvirus detection has improved the sensitivity and specificity of diagnosis, as it is able to detect shedding episodes in the absence of clinical lesions and diagnose clinical specimens that have low viral loads. With an aim to improve the detection and quantification of herpesvirus b

6. CHARACTERIZING THE MECHANISM OF QUETIAPINE DISTRIBUTION IN LIPID-CORE NANOCAPSULES PSEUDO-PHASES USING A VALIDATED LC/UV METHOD
Quetiapine is an atypical antipsychotic used to treat schizophrenia. However, despite great interest for its chronic therapeutic use, quetiapine has some important side effects such as weight gain induction. The development of a quetiapine nanocarrier can potentially target the drug into central nervous system, resulting in a reduction of systemic side effec

7. Development and validation of a RP-HPLC method to determine the xanthyletin content in biodegradable polymeric nanoparticles
Xanthyletin is used as an inhibitor of the symbiotic fungus (Leucoagaricus gongylophorus) of the leaf-cutting ant (Atta sexdens rubropilosa), one of the most significant agricultural plague insects. The incorporation of this compound into nanoparticles is a promising approach to effectively control leaf-cutting ants. This study presents the development and v

8. Absolute quantification of fatty acid and proximate composition of cow and goat powdered milks
Este trabalho investigou a qualidade lipídica de leites processados por quantificação de ácidos graxos. Dez amostras de leite em pó integral de vaca e duas de cabra foram submetidas à extração de lipídios totais e à preparação dos ésteres metílicos de ácidos graxos. Estes foram separados em cromatógrafo a gás. A variação da quantidade de �

9. Benzo(a)pireno, carbamato de etila e metanol em cachaças
The objective of this work was to evaluate the presence of benzo(a)pyrene (BaP), ethyl carbamate (EC) and methanol in 61 samples of cachaça. The quantification of BaP was carried out using HPLC with fluorescence detection, EC concentrations was determined by GC/MS and that of methanol, by GC/FID. In all samples, the concentration of methanol remained below

10. Comparative quantification of umbilical cord blood CD34+ and CD34+ bright cells using the procount tm-bd and ishage protocols
The total number of CD34+ cells is the most relevant clinical parameter when selecting human umbilical cord blood (HUCB) for transplantation. The objective of the present study was to compare the two most commonly used CD34+ cell quantification methods (ISHAGE protocol and ProCount™ - BD) and analyze the CD34+ bright cells whose 7-amino actinomycin D (7AAD

12. Estudo da perfusão miocárdica e reserva coronariana pela ecocardiografia sob estresse com perfusão em tempo real em pacientes com diabetes melito descompensado e após tratamento / Myocardial perfusion study and coronary flow reserve by real-time utilizing myocardial contrast echocardiography in decompensated diabetic patients after treatment
Background: Diabetes mellitus (DM) is associated with alterations in coronary flow reserve on microvascular circulation. Real-time myocardial contrast echocardiography has proven to be a useful method for non-invasive evaluation of microvascular alterations. The objective of this study was to assess whether the control of diabetes would influence the values
