OBJECTIVE To review the distribution of orbital and intracranial disease in canine and feline patients undergoing magnetic resonance imaging (MRI) following referral to a veterinary ophthalmologist and to correlate results of MRI with pathologic conditions including neoplasia, suspected optic neuritis (ON) and orbital cellulitis. Recognized and emerging(More)
Uropathogenic Escherichia coli (UPEC) is responsible for the majority of urinary tract infections (UTIs), which are some of the world's most common bacterial infections of humans. Here, we examined the role of FNR (fumarate and nitrate reduction), a well-known global regulator, in the pathogenesis of UPEC infections. We constructed an fnr deletion mutant of(More)
Two-component signaling systems (TCSs) are major mechanisms by which bacteria adapt to environmental conditions. It follows then that TCSs would play important roles in the adaptation of pathogenic bacteria to host environments. However, no pathogen-associated TCS has been identified in uropathogenic Escherichia coli (UPEC). Here, we identified a novel TCS,(More)
BACKGROUND The molecular identification and characterization of the adenosine triphosphate (ATP)-sensitive family of P2 receptors is comparatively new. There are two main subgroups, each with several subtypes and widespread tissue distribution, including the kidney. A unique member of the P2X subgroup of P2 receptors is the ATP-gated ion channel P2X(7),(More)
Paragangliomas are uncommon tumours that comprise less than 0.1% of all primary bladder neoplasms. Approximately half of the patients present the clinical triad of hypertension, haematuria and attacks associated with micturition. About 10% of vesical paragangliomas behave malignantly. This may be manifested as local invasion or metastatic spread,(More)
A rare case of adenocarcinoma of the duodenal bulb, arising from adenoma and submitted to Whipple's procedure is presented. A diagnostic delay of about 3 months, according to literature is observed. This delay is generally due to the low incidence of the illness, aspecific symptoms and frequent endoscopic and radiologic false negative, most of all in(More)
