First description and evaluation of SNPs in the ADH and ALDH genes in a population of alcoholics in Central-West Brazil.

Worldwide, different studies have reported an association of alcohol-use disorder (AUD) with different types of Single Nucleotide Polymorphisms (SNPs) in the genes for aldehyde dehydrogenase (ALDH) and alcohol dehydrogenase (ADH). In Brazil, there is little information about the occurrence of these SNPs in the AUD population and an absence of studies characterizing the population in the Central-West Region of Brazil. Actually, in Brazil, there are more than 4 million people with AUD.

TransCelerate's Clinical Quality Management System: From a Vision to a Conceptual Framework.

The Quality Management System (QMS) initiative of TransCelerate BioPharma Inc has identified potential benefits that could be captured from the development of a flexible, proactive clinical QMS conceptual framework for clinical research. Such a framework would aid organizations in seamlessly managing the complex clinical trial environment and, ultimately, in expediting delivery of needed treatments to patients. This article chronicles the evolution of a TransCelerate concept paper describing a proposed clinical QMS framework and reviews feedback from varied global clinical trial stakeholders during socialization of the concept paper.

Loss of Y-chromosome does not correlate with age at onset of head and neck carcinoma: a case-control study.

Loss of Y-chromosome has been correlated with older age in males. Furthermore, current evidence indicates that Y-chromosome loss also occurs in several human tumors, including head and neck carcinomas. However, the association between Y nullisomy and the occurrence of neoplasias in elderly men has not been well established.

Recurrent copy number gains of ACVR1 and corresponding transcript overexpression are associated with survival in head and neck squamous cell carcinomas.

Aims: This study aimed to evaluate the copy number alteration on 2q24, its association with ACVR1 transcript expression and the prognostic value of these data in head and neck squamous cell carcinomas.

Methods And Results: Twenty-eight samples of squamous cell carcinoma were evaluated by fluorescence in situ hybridization (FISH) using the probes RP11-546J1 (2q24) and RP11-21P18 (internal control). Significant gains at 2q24 were detected in most cases at frequencies varying from 3 to 35%.

Quantitative real-time RT-PCR and chromogenic in situ hybridization: precise methods to detect HER-2 status in breast carcinoma.

Background: HER-2 gene testing has become an integral part of breast cancer patient diagnosis. The most commonly used assay in the clinical setting for evaluating HER-2 status is immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). These procedures permit correlation between HER-2 expression and morphological features.
