background: several grafting materials have been used for alveolar ridge augmentation. the literature lacks researches to compare cenobone to other grafting materials. the aim of this study was to compare cenobone/cenomembrane complex to bio-oss/bio-gide complex in lateral alveolar bone augmentation in terms of radiographic, histologic, and histomorphometric parameters. materials and methods: i...
The purpose of this study was to examine the correlation between high-resolution magic angle spinning (HR-MAS) magnetic resonance (MR) spectroscopy using core needle biopsy (CNB) specimens and histologic prognostic factors currently used in breast cancer patients. After institutional review board approval and informed consent were obtained for this study, CNB specimens were collected from 36 ma...
The majority of low-grade non-Hodgkin's lymphomas (NHL) undergo clinical progression toward intermediate- and high-grade lymphomas. This progression is often associated with histologic transformation from follicular to diffuse-type NHL. The pathogenetic mechanisms underlying this evolution are presently unknown. In this study, we have analyzed the role in NHL progression of relevant genetic les...
BACKGROUND Important differences in the contributions of certain exposures to the risks of ductal versus lobular breast carcinomas have been observed, but few studies have evaluated the relationships between established breast cancer risk factors and other histologic types. METHODS Information on family history of cancer and reproductive, hormonal, anthropometric, and lifestyle characteristic...
Background: The navicular syndrome may be associated with alterations in other podotrochlear apparatus components, such as the deep digital flexor tendon, collareral sesamoid and distal ligaments, bursa bone. However, clinical significance nature of these changes are not well understood, many descriptive reports about bone lesions rarely accompanied by a complete comprehensive comparison animal...
Histologic grade is one of the most important microscopic features used to predict the prognosis of invasive breast cancer and may serve as a marker for studying cancer driving genomic abnormalities in vivo. We analyzed whole genome sequencing data from 680 cases of TCGA invasive ductal carcinomas of the breast and correlated them to corresponding pathology information. Ten genetic abnormalitie...
BACKGROUND Histologic grade in breast cancer provides clinically important prognostic information. However, 30%-60% of tumors are classified as histologic grade 2. This grade is associated with an intermediate risk of recurrence and is thus not informative for clinical decision making. We examined whether histologic grade was associated with gene expression profiles of breast cancers and whethe...
BACKGROUND Confocal reflectance microscopy (CRM) is an optical method of imaging tissue noninvasively without the need for fixation, sectioning, and staining as in standard histopathologic analysis. Image contrast is determined by natural differences in refractive indices of organelles and other subcellular structures within the tissues. Gray-scale images are displayed in real time on a video m...
