background and objectives:rapid processing of histopathological specimens and decreased turnaround time is important to fulfill the needs of clinicians treating sick patients, so the present study was conducted to compare the time taken and quality of sections in processing of prostatic tissue by rapid microwave and conventional techniques using morphometry.methods: four to five mm thick paired...

background one of the main challenges in skin flap surgery is tissue ischemia and following necrosis. the present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. methods thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal random-pattern skin ...

The histological growth pattern (HGP) of solid tumor metastases to liver is an easy-to-assess and integrative histopathological parameter of tumor-stromal interactions [1]. With preliminary data suggesting that theHGPof colorectal cancer liver metastases has prognostic value [2], we hypothesize that it also might predict response to therapy [1, 3]. To enhance pathological assessments, we organi...

The study describes the topography, morphology and growth of osteophytes in forty femoral heads removed from patients presenting with advanced osteoarthritis of the hip. In addition to standard histological techniques, radiography of serial bone slices in vivo bone labelling with tetracycline and 32P were used. The pattern of major osteophyte formation appeared to be influenced by the direction...

Lung squamous cell carcinoma (SCC) has always been considered a monomorphic entity, different from lung adenocarcinoma which is known to be a very heterogeneous tumor from morphological and molecular point of view. Just two histological subtypes of SCC are recognised, the basaloid and lymphoepithelioma-like histotypes, as in other sites different from the lung. Recently, different studies tried...

OBJECTIVES Classification of non-small-cell lung cancer (NSCLC) into growth patterns is based on the following question: What does the tumour do with normal lung parenchyma? There are only three possible ways according to which a tumour can behave: (1) preservation of lung tissue and use of its microenvironment for further growth, (2) destruction of lung tissue and formation of new microenviron...

p53 Protein accumulation in early gastric carcinoma was studied in relation to the histological type (Lauren classification) and the type of growth pattern, including the chronology of p53 protein accumulation during carcinogenesis. Forty five, paraffin embedded gastrectomy specimens from early carcinomas were examined for the presence of chronic atrophic gastritis, subtypes of intestinal metap...

(1989) A comparison between operative and non-operative management of blunt injuries to the liver and spleen in adult and pediatric patients. Management of blunt trauma to the liver and hepatic veins. Natural history of small untreated hepatocellular carcinoma in cirrhosis: A multi-variate analysis of prognostic factors of tumour growth rate and patient suroival. We analyzed the growth pattern ...

Sevento eight-day mouse tail vertebrae were transplanted under the renal capsules of syngeneic adult animals and allowed to grow for up to 6 months. Their curve of growth and histological pattern of ageing were similar to those of control vertebrae which had been left in their normal position on young animals. Slices of the growth cartilage of sevento eight-day rat tail vertebrae were similarly...
