BACKGROUND AND OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) is a well-known pathogen with a worldwide distribution. Given the increasing rate of MRSA infections, implementing of reliable, accurate and rapid testing for diagnosis of MRSA is necessary. The aim of this study was to compare four diagnostic methods for detection of MRSA isolates. MATERIALS AND METHODS From Decembe...

OBJECTIVE To investigate the effects of posterior implant rigidity on spinal kinematics at adjacent levels by utilizing a cadaveric spine model with simulated physiological loading. METHODS Five human lumbar spinal specimens (L3 to S1) were obtained and checked for abnormalities. The fresh specimens were stripped of muscle tissue, with care taken to preserve the spinal ligaments and facet joi...

The influence of specimen size on the measured values true mode II fracture toughness (KIIc) rocks have been investigated both experimentally and theoretically. In experimental study, double-edge notched Brazilian disk (DNBD) test is utilised to perform experiments with various radii ranging from 27 101 mm. Test results demonstrate a significant increase KIIc size. reason for this trend explain...

Background Since 1996, when Vivo questioned how many species of mammals occur in Brazil, there has been a huge effort to assess this biodiversity. In this contribution, we present new records for rare species of the sigmodontine rodent genera Rhagomys and Neusticomys previously unknown to Brazilian Amazon. We provided detailed information on the morphologic variation to allow the proper identif...

The biological effect of wear of articulating surfaces is a continued concern with large joint replacements and, likewise, of interest for total disc replacements. There are a number of important biotribological testing parameters that can greatly affect the outcome of a wear study in addition to the implant design and material selection. The current ASTM and ISO wear testing standards/guides f...

STUDY DESIGN An autograft of costal cartilage was transplanted into the rat intervertebral space in the proximal tail following 2 weeks of simulated degeneration by chondroitinase ABC (CABC). OBJECTIVES The purpose of this study was to evaluate costal cartilage transplantation into a degenerated disc as a possible therapy. SUMMARY OF BACKGROUND DATA Reversal of degenerative disc dehydration...

Background and Aims: Rotaviruses are one of the main causative agents of acute viral gastroenteritis in both young human and animals. Several methods have been used for diagnosis of rotavirus infection. Most of these methods are not easily available in Iran. Methods: In our study attempt was made to develop a method which could replace the commercially imported Kit. Rota virus was purified and...

During necropsy of a specimen of Lagothrix cana (É. Geoffroy, 1812) (Primates: Atelidae) from the Brazilian Amazon, pinworms were found in the large intestine. The intensity of infection was 64 parasites (17 males and 47 females) and there were no gross pathological changes related to parasitism. After morphological analysis the parasites were identified as Trypanoxyuris (Paraoxyuronema) lagoth...
