A study was made of the intrinsic radiosensitivity of 140 biopsy and surgical specimens of malignant head and neck tumours of different histologies.
At 50 or 100 micrometer intervals, depending on size, specimens of the head were processed for sagittal or horizontal sections, each 5 micrometers thick.
The purpose of this study was (i) to examine the expression of CD133 in surgical specimens of pancreatic head carcinoma by immunohistochemical methods, (ii) to explore possible correlation between CD133 expression and clinicopathological variables, (iii) to correlate expression of CD133 with VEGF-C, and (iv) to determine the prognostic value of CD133 expression.
Weinstein and his colleagues have studied osteocyte apoptosis in femoral head specimens of 14 patients with necrosis of the femoral head using TUNEL staining assay [ 5], showing the appearance of marked osteocyte apoptosis in specimens from patients with SANFH, while apoptosis was absent or rare in specimens from patients with necrosis of the femoral head caused by other factors.
Immunohistochemical analysis of tumour specimens from head and neck cancer patients treated with the combination of nimotuzumab and radiation also showed evidence of antiproliferative and antiangiogenic effects (Crombet et al, 2004).
Sections of head and neck cancer specimens known to express MET served as positive controls (Perisanidis et al, 2012).
In the first specimen the head of the bone is seen above the rim of the acetabulum dislocated upward and forward.
Finally, we profiled levels of c-MET, HGF, and HGF-c-MET complexes in FFPE specimens of human Non-Small Cell Lung Cancer (NSCLC), Gastric Cancer, Head and Neck Squamous Cell, and Head and Neck Non-Squamous Cell carcinomas.
Tissue microarrays of primary human cancer specimens (ccRCC, head & neck and colon) were utilized to determine the incidence of PHD2/3, HIF-α, and VEGF-A by immunohistochemical methods.
In the cases of specimens retrofitted with head re-bars, V s is calculated according to KCI (2012).
