Background and purpose: Salivary gland neoplasms are heterogeneous and have low prevalence. Hematoxylin- eosin staining is used for their diagnosis, however, sometimes diagnosis may not be made by this method, so other methods are necessary. The aim of this study was to determine whether morphometry is an appropriate method in differentiating benign and malignant salivary tumors or not. Mate...
Butea monosperma (Lam.) (family: Fabaceae) popularly known as 'Palas' or 'fire of forest' has been used traditionally as a hepatoprotective agent. This study evaluated the hepatoprotective and antitumorigenic properties of the aqueous extract and butanol fractions of B. monosperma flowers in animal models. Dried flowers of B. monosperma were extracted with water and fractionated further using n...
Prognostic factors in organ confined prostate cancer will reflect survival after surgical radical prostatectomy. Gleason score, tumour volume, surgical margins and Ki-67 index have the most significant prognosticators. Also the origins from the transitional zone, p53 status in cancer tissue, stage, and aneuploidy have shown prognostic significance. Progression-associated features include Gleaso...
BACKGROUND Atypia of undetermined significance (AUS) is a category that encompasses a heterogeneous group of thyroid aspiration cytology. It has been reclassified into two subgroups based on the cytomorphologic features: AUS with cytologic atypia and AUS with architectural atypia. The nuclear characteristics of AUS with cytologic atypia need to be clarified by comparing to those observed in Has...
In order to investigate the chemical composition of the nuclear pore complexes isolated nuclei from mature Xenopus laevis oocytes were manually fractioned into nucleo· plasmic aggregates and the nuclear envelopes. The whole isolation procedure takes no more than 6090 sec, and the pore complexes of the isolated envelopes are well preserved as demonstrated by electron microscopy. Minor nucleoplas...
In order to determine the possible influence in oesophageal squamous cell carcinoma of nuclear measurements on patients' postoperative survival and on various histological tumour features, we performed a nuclear morphometry study on 53 patients (50 males, 3 females) with a mean age of 57.4 years (37-79). A statistical correlation was revealed between area, perimeter and diameter and the analysi...
