Predicting lymph node metastasis (LNM) accurately is of great importance to formulate optimal treatment strategies preoperatively for patients with early gastric cancer (EGC). This study aimed to explore risk factors that predict the presence of LNM in EGC. A total of 697 patients underwent gastrectomy enrolled in this study, were divided into training and validation set, and the relationship b...
Harnessing diversity from germplasm collections is more feasible today because of the development of lower-cost and higher-throughput genotyping methods. However, the cost of phenotyping is still generally high, so efficient methods of sampling and exploiting useful diversity are needed. Genomic selection (GS) has the potential to enhance the use of desirable genetic variation in germplasm coll...
Dependable Systems for Sentient Computing Andrew Rice Computers and electronic devices are continuing to proliferate throughout our lives. Sentient Computing systems aim to reduce the time and effort required to interact with these devices by composing them into systems which fade into the background of the user’s perception. Failures are a significant problem in this scenario because their occ...
The characteristic of a biomarker that makes it a useful surrogate is the ability to identify a high risk of clinically important benefits or harms occurring in the future. A number of definitions or descriptions of surrogate definition have been put forward. Most recently the Institute of Medicine of the National Academy of Sciences in the USA has put forward an evaluation scheme for biomarker...
Purpose: To use gene transcript profiling to identify cancer-associated gene expression. Experimental Design: Methods included (i) marker discovery using laser capture microdissection (LCM)-assisted specimen preparation and antisense RNA-long serial analysis of gene expression (aRNALongSAGE) on matched colon cancer and uninvolved colon tissue specimens (n 1⁄4 5). Candidate tumorassociated genes...
PURPOSE The aim of this study was to develop a validated, reliable, and minimally invasive technique for diagnosing limbal stem cell deficiency (LSCD) by immunocytochemical detection of conjunctival and corneal keratins on epithelial cells collected by impression cytology (IC). METHODS After validation of labeling techniques on a cohort of 10 healthy control patients, keratins K12, K13, and K...
