1. Methods for blood group antigens detection: cost-effectiveness analysis of phenotyping and genotyping
Abstract Background Alloimmunization is a major problem in transfusion practice due to the clinical complications of the patients and the difficulty of choosing a unit of compatible blood product. Serological methods are widely used in blood banks, but they not always determine the phenotype. Thus, genotyping is an important complement to the serology tool

2. PCR-RFLP assay as an option for primary HPV test
Persistent human papillomavirus (HPV) infection is an essential factor of cervical cancer. This study evaluated the analytical performance of restriction fragment length polymorphism polymerase chain reaction (PCR-RFLP) assay compared to PapilloCheck® microarray to identify human papilloma virus (HPV) in cervical cells. Three hundred and twenty-five women w

3. Differential gene expression profiles in peripheral blood in Northeast Chinese Han people with acute myocardial infarction
Abstract This study aimed to use gene chips to investigate differential gene expression profiles in the occurrence and development of acute myocardial infarction (AMI). The study included 12 AMI patients and 12 healthy individuals. Total mRNA of peripheral bloodwas extracted and reversed-transcribed to cDNA for microarray analysis. After establishing two poo

4. Identification of genes related to high royal jelly production in the honey bee (Apis mellifera) using microarray analysis
Abstract China is the largest royal jelly producer and exporter in the world, and high royal jelly-yielding strains have been bred in the country for approximately three decades. However, information on the molecular mechanism underlying high royal jelly production is scarce. Here, a cDNA microarray was used to screen and identify differentially expressed ge

6. Identification of therapeutic target genes with DNA microarray in multiple myeloma cell line treated by IKKβ/NF-κB inhibitor
PURPOSE: To explore the mechanism of resistance to IKKβ inhibitor in multiple myeloma (MM) cells and uncover novel therapeutic targets for MM.METHODS: We downloaded the microarray data (GSE8476) from GEO (Gene Expression Omnibus) database. The data were derived from the human MM cells lines (L363 cells) treated with IKKβ inhibitor MLN120b (MLN) for eight,

7. Stability of XIST repression in relation to genomic imprinting following global genome demethylation in a human cell line
DNA methylation is essential in X chromosome inactivation and genomic imprinting, maintaining repression of XIST in the active X chromosome and monoallelic repression of imprinted genes. Disruption of the DNA methyltransferase genes DNMT1 and DNMT3B in the HCT116 cell line (DKO cells) leads to global DNA hypomethylation and biallelic expression of the imprin

8. Effects of BST and high energy diet on gene expression in mammary parenchyma of dairy heifers
The objective of this study was to determine the effects of dietary energy and recombinant bovine somatotropin (bST) injection to identify genes that might control mammogenesis. Total RNA was extracted from the parenchymal tissue of 32 heifers randomly assigned to one of four treatments: two diets (a standard diet and a high energy, high protein diet), each

9. Análise de proteínas cuja expressão é controlada por miRNA e relacionada à progressão do adenocarcinoma de próstata por imuno-histoquimica em tissue microarray / Analysis of proteins whose expression is controlled by miRNA and related to the progression of prostate adenocarcinoma by immunohistochemistry on tissue microarray
Introdução: O Câncer de Próstata (CaP) é o tumor mais comum do homem e a segunda causa de óbito por câncer no Brasil. MicroRNA (miRNA) é uma classe de pequenos RNA regulatórios não codificantes de proteínas que tem papel fundamental no controle da expressão dos genes. São responsáveis pelo controle de processos fundamentais na célula e estão

10. Estudo da expressão das proteínas TFE3 e receptor de insulina nos hepatoblastomas a partir dos achados de expressão gênica / Effectiveness of auditory training through evoked potentials to complex sound in hearing and language disorders
O hepatoblastoma é uma neoplasia embrionária hepática que ocorre na faixa pediátrica, rara, sendo bastante heterogênea devido aos seus diferentes componentes epiteliais e mesenquimais. Pouco ainda se sabe a respeito de sua patogênese. Utilizando um microscópio de captura a laser foram dissecadas áreas de componente epitelial do hepatoblastoma e área

12. Análise do microtranscritoma em variedades de cana-de-açúcar (Saccharum spp.) submetidas a estresse hídrico / Microtranscriptome analysis of sugarcane (Saccharum spp.) cultivars under drought stress
Sugarcane (Saccharum spp.) is amongst the most relevant crops in the world and Brazil is the most prominent producer. It is an inexpensive and efficient source for commodities such as sugar and ethanol, the latter being increasingly considered the most promising immediate energy source substitute for oil, mainly in transportation. Apart from being very produ
