We aimed to compare the assay performance characteristics of HER2 status in mucinous epithelial ovarian cancer (EOC) by ToGA (Trastuzumab for Gastric Cancer) biopsy versus ToGA surgical specimen methods. Forty-nine tissue microarray (TMA) samples of mucinous EOC from Asian women were analyzed by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) tests using ToGA trial HER2...

i have carried out 22 biopsies in 20 patients, in fifteen i used a vim _ silverman needle, and in the remainder a curetting type needle, in 12 cases (60%) the diagnosis that was made; in 3 cases, inadequate tissue, was obtained; in two cases a fibromuscular tissue, in one case a fatty tissue and in one case the specimen was of hepatic tissue. even with the small biopsy specimen obtained with th...

Urinary tract infections are the most commonly acquired bacterial infections, but the significance of growths from catheter-related specimens, particularly heavy mixed growths, is uncertain and can pose a dilemma for the clinical laboratory responsible for processing and authorising reports, as well as a diagnostic dilemma for clinicians. Furthermore, inappropriate processing and reporting of s...

Arguments are presented for the merit of integrating specimen databases into the practice of revisionary systematics. Work flows, data connections, data outputs, and data standardization are enumerated as critical aspects of such integration. Background information is provided on the use of "barcodes" as unique specimen identifiers and on methods for efficient data capture. Examples are provide...

This document contains revised guidelines developed by CDC for laboratories performing lymphocyte immunophenotyping assays in human immunodeficiency virus-infected persons. The recommendations in this document reflect current technology in a field that is rapidly changing. The recommendations address laboratory safety, specimen collection, specimen transport, maintenance of specimen integrity, ...

Most thoracic surgeons have encountered a number of situations in which a specimen was too large to fit through a small intercostal incision. This report highlights a useful technique for specimen extraction from the thorax using a vinyl bag and a sucker. The sucker creates negative pressure, and the liquid and air components from the specimen are removed. The specimen can be deflated and remov...

In order to study the shrinkage process of clayey soil, we perform a modified laboratory test allowing to measure simultaneously and continuously the vertical displacement and the weight of natural state specimen. The experiment was conducted on undisturbed clayey specimen. Using the experimental results, and on the basis of the existing relation between the soil water content and its structura...
