Cervical metaplastic squamous epithelium exhibiting atypia insufficient for a diagnosis of cervical intraepithelial neoplasia (CIN) is usually reported as "atypical squamous metaplasia" (ASM). Stratification impacts treatment since the differential is often between reactive and high grade CIN (CIN II, III). Diagnosis with H&E is associated with low intra/interobserver concurrence. P16/Ki-67 imm...

The antigen defined by mAb Ki-67 is a human nuclear protein the expression of which is strictly associated with cell proliferation and which is widely used in routine pathology as a "proliferation marker" to measure the growth fraction of cells in human tumors. Ki-67 detects a double band with apparent molecular weights of 395 and 345 kD in immunoblots of proteins from proliferating cells. We c...

The aim of the present study was to investigate if macrophage proliferation occurs in the brain during simian immunodeficiency virus (SIV) infection of adult macaques. We examined the expression of the Ki-67 proliferation marker in the brains of uninfected and SIV-infected macaques with or without encephalitis. Double-label immunohistochemistry using antibodies against the pan-macrophage marker...

BACKGROUND Hypoxia-induced changes may allow tumor cells to survive under sustained hypoxic microenvironments resulting in achievement of more aggressive phenotypes. The purpose of this study is to determine the prognostic relevance of the expression of carbonic anhydrase IX (CA IX), a hypoxia-related protein in surgically resected squamous cell carcinoma of the tongue. We also relate CA IX to ...

PURPOSE Proliferative activity defined by Ki-67 staining index (SI) has been correlated with progression and prognosis in a number of malignant tumors including prostate cancer. However, few studies have examined Ki-67 SI in pretreatment diagnostic material from patients treated with definitive radiotherapy. In a prior study, we found that a Ki-67 SI of >3.5% was associated with poorer patient ...

Povzetek. V prispevku obravnavamo pristop za prilagajanje procesa razvoja programske opreme potrebam konkretnih projektov, ki se izvajajo v podjetjih za razvoj programske opreme. Predlagan pristop je bistveno preprostejši od dosedanjih pristopov, ki jih opredeljuje področje konstruiranja metodologij. V okviru predstavitve pristopa opredelimo odločitvena pravila, ki usmerjajo postopke izbire ust...
