BACKGROUND Micronuclei (MN) in oral exfoliative cells have been shown to indicate a disparaging change in genetic information of the cell. Recent studies showed correlation between the frequency of MN and severity of this damage. Grading of lesions can be used to determine the austerity of this damage. Aims: The aim of this study is to compare the MN frequency in oral exfoliated cells of normal...

BACKGROUND Lung adenocarcinoma is often composed of a complex and heterogeneous mixture of histological subtypes. Invasive adenocarcinomas are now classified by their predominant pattern, using the comprehensive histological subtyping of the International Association for the Study of Lung Cancer (IASLC), the American Thoracic Society (ATS), and the European Respiratory Society (ERS) classificat...

The sensitive and autonomic innervation of foot pads in the ostrich was studied employing an usual histological technique as hematoxylin-eosin or different gold chloride impregnations. The autonomic innervation is represented by isolated or grouped ganglion cells located along the course of nerve bundles. The sensitive somatic innervation is composed by free and capsulated nerve endings usually...

BACKGROUND Thyroid core biopsies obtained with ultrasound (US)-guided needles are an alternative to conventional fine-needle aspiration and, according to various authors, have greater sensitivity and specificity. The technique is inexpensive, rapid and reliable with a low rate of complications, similar to conventional fine-needle aspiration procedures. OBJECTIVES This paper critically reviews...

After manual and machine cleaning of beef intestines, the structure of the intestinal layer was examined. Examination was performed using a histological technique and included 60 intestinal sets of fattened beef (Simmental breed), 10 months of age and with an average slaughter weight of 248.05 kg. Intestines are considered to be edible by-products and therefore are used as natural casings for h...

Our knowledge of neoplasms, notwithstanding the enormous amount of research to which they have been subjected, is still extremely vague and unsatisfactory. With nearly every advance in histological technique, however, its application to tumors has afforded some additional fact or facts concerning them, and it is only by utilizing for their study the various improvements of older methods or enti...

The present study was conducted to describe the histological features of parotid and submandibular salivary glands of European hamster. The glands samples were obtained from five adult males and microscopic slides were prepared using routine histological technique. The results showed that these glands divide in lobes associated with the ducts. The parotid was a typical serous gland, but the sub...

CONTEXT Diagnostic staging is an important prognostic factor for endometrial adenocarcinoma. Apart from the histological type and histological grade, some markers seem to be associated with the stage and biological behavior of the disease. Among these are p53, estrogen and progesterone receptors. OBJECTIVE The objectives of the present study were: to compare histological type and grading of e...

background: the vegf is essential in the process of tissue remodeling and angiogenesis. limited data is available on the expression and regulation of vegf and its receptors in the human endometrium. the aim of this study was evaluation of expression patterns of vegf and flk-1 in human endometrium during the menstrual cycle. methods: sixty paraffin-embedded blocks of endometrial tissues from the...

Background & Objective: Gliomas are the most common type of primary intracranial tumors in adults. The expression of estrogen receptors varies in different grades of glial tumors, and some studies have suggested that this expression might have a prognostic value. It seems that estrogen receptor expression negatively correlates with the histological grade of gliomas. In the pres...
