Tissues were fixed in formalin for routine pathological assessment and one specimen of non-tumorous liver distant to tumor was immediately snap frozen in liquid nitrogen and stored at −80°C until use.
Plasma cells were rarely observed in the section of a biopsy specimen of non-neoplastic oropharyngeal mucosa.
NBEC cells were isolated and cultured from lung specimens of non neoplastic origin.
Butterfly-shaped specimens of non-uniform cross-section are used for the second series to study the onset of fracture in the martensitic steel.
In this paper, the fatigue behavior of laser welds in lap-shear specimens of non-galvanized SAE J2340 300Y high strength low alloy (HSLA) steel sheets is investigated based on experimental observations and a fatigue life estimation model.
Human pancreatic specimens of non-diabetic subjects were obtained from normal pancreas removed at surgery for pancreatic adenomas from the Mayo Clinic (Rochester, MN).
Biopsy specimens of non-neoplastic Barrett's metaplasia demonstrate inactivation of p16 via promoter methylation, loss of heterozygosity (LOH), or mutation in 73% to 87% of patients [15], [16].
In biopsy specimens of non-dysplastic Barrett's metaplasia, allelic loss of p53 occurs more frequently than p53 mutation and, in the absence of p53 allelic loss, p53 mutations are rare [16], [17].
We have developed cultures of human Barrett's epithelial cells from esophageal biopsy specimens of non-neoplastic Barrett's metaplasia, and we have immortalized those cells by forcing them to express telomerase.
In this study we use laser scanning (LiDAR) and computer modelling methods to create a range of 3D mass models of five specimens of non-avian dinosaur; two near-complete specimens of Tyrannosaurus rex, the most complete specimens of Acrocanthosaurus atokensis and Strutiomimum sedens, and a near-complete skeleton of a sub-adult Edmontosaurus annectens.
We used 2 non-neoplastic, telomerase-immortalized Barrett's epithelial cell lines (BAR-T and BAR10-T) that were established in our laboratory from endoscopic biopsy specimens of non-dysplastic Barrett's specialized intestinal metaplasia taken from two patients with long-segment Barrett's esophagus [5], [32].
