Quantitative characterization of agglomerates and aggregates of pyrogenic and precipitated amorphous silica nanomaterials by transmission electron microscopy.
and agglomerates. A method based on transmission electron microscopy (TEM), to visualize the NM and on image analysis, to measure detected features quantitatively, was assessed for its capacity to ...
DNA ploidy and nuclear morphometric variables for the evaluation of melanocytic tumors in dogs and cats.
melanocytic tumors of cats and dogs. SAMPLE POPULATION: 27 melanocytic tumors of dogs and cats. PROCEDURES: Biopsy specimens were investigated by quantitative image analysis after the Feulgen staining method. ...
Proliferation, DNA ploidy, p53 overexpression and nuclear DNA fragmentation in six equine melanocytic tumours.
immunostaining, DNA nick end labelling (Tunel) and Feulgen staining. The stainings were evaluated using quantitative image analysis. The resulting parameters of growth fraction (Ki67), S-phase index (PCNA), p53 ...
PCNA and Ki67 proliferation markers as criteria for prediction of clinical behaviour of melanocytic tumours in cats and dogs.
quantitative image analysis of tissue sections immunolabelled for proliferating cell nuclear antigen (PCNA) and MIB-1 (Ki67). Lesions classified histologically as benign or malignant, differed significantly ...
Successful treatment of an equine preputial fibrosarcoma using 5-fluorouracil/evaluation of the treatment using quantitative PCNA and Ki67 (MIB 1) immunostaining. (case report).
related factor–Ki67 (MIB1). Using computerized quantitative image analysis of these sections, Mitotic index (PCNA), Growth Fraction (Ki67) and total nuclear area percentage of the dermis were calculated. ...
