The neurocognitive consequences of non-functioning pituitary adenoma and its treatment
Patients with pituitary adenoma often report problems with cognitive function. However, the current literature is inconsistent on the types of cognitive deficits that patients experience. Chapter 1 of this thesis reviews the current literature and the questions that are still unanswered concerning …

Longer Right Colon Withdrawal Time and Retroflexion Duration Significantly Increases Adenoma Detection Rate: A Randomized Controlled Trial at Three Endoscopy Centers
Purpose Detection of adenomas is the foundation of colorectal cancer screening utilizing screening colonoscopies. Adenoma detection rate (ADR) is an increasingly utilized core quality measure for colonoscopies. Colonoscopy is an effective tool to prevent colon cancer but missed lesions can lead to …

A bioinformatics meta-analysis of differentially expressed genes in colorectal cancer
… studies that compared cancer versus normal, adenoma versus normal, and cancer versus adenoma tissues. RESULTS: We observed that some genes were consistently reported as differentially expressed with a statistically significant frequency (P <.0001) in the cancer versus normal and adenoma …

Differentiating follicular thyroid carcinoma from the follicular variant of papillary thyroid carcinoma
Introduction: Differentiating follicular adenoma (FA), follicular thyroid carcinoma (FTC) and follicular variant of papillary thyroid carcinoma (FVPTC) remain a diagnostic challenge in some cases. This is as a result of the assessment of nuclear features being highly subjective, and the threshold …

Telomeric Regulation of Chromosomal Instability In Colorectal Cancer
… (CIN) during the transition from benign adenoma to malignant adenocarcinoma. While CIN provides a mutator mechanism for cancer-relevant genomic events, its role in shaping tumor biology during carcinogenesis is not well understood. Here, we explored the molecular and biological impact of …

Folic acid in preventing recurrence of colorectal adenomas : is it effective?
… incidence of patients with recurrent colorectal adenomas have increased interest among researchers in finding a vitamin supplement which may act as a chemo-preventive agent against the development of these lesions. Folic acid was found to be beneficial for various health reasons and also was …

Morphologische Grundlagen der Schilddrüsensonographie bei der Katze
… 48 out of 101 animals - nodular hyperplasia and adenomas have been found. Sonographic examination revealed characteristic features of nodular hyperplasia and adenoma cases. However, these examinations could not provide reliable distinctive marks. In addition, two adenocarcinomas were found. Their …

Nherf1 – New Modifier of Colorectal Cancer Progression
… had significant alterations from normal to adenoma and carcinoma transitions (2=38.5, d.f.=4, P<0.001), displaying apical membrane localization in normal tissue but loss of expression in adenoma and ectopic overexpression in carcinoma. In Caco-2 cell models, NHERF1 depletion induced …

Metabolomic Biomarkers for Colorectal Cancer
… a larger study of 320 CRC and 31 colorectal adenoma cases as well as their matching controls by GC-MS, which led to the identification of validated metabolomic signature for identification of CRC and a proposed signature for identification of colorectal adenoma. In chapter 4, an effort for …
