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...

Animal models of intervertebral disc degeneration play an important role in clarifying the physiopathological mechanisms and testing novel therapeutic strategies. The objective of the present study is to describe a simple animal model of disc degeneration involving Wistar rats to be used for research studies. Disc degeneration was confirmed and classified by radiography, magnetic resonance and ...

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...
