OBJECTIVES To analyze retrograde conduction during junctional ectopic tachycardia (JET) episodes and investigate the existence of a relationship between the presence of a retrograde block and the risk of atrioventricular block (AVB) development during radiofrequency ablation procedures in patients with nodal atrioventricular tachycardia (NAVT). METHODS 145 male and female patients aged 16-84 ...

Morphological ly atypical mi tochondr ia have been reported by m a n y investigators. Those possessing a cupped shape have been found in presumably normal cells of endocrine organs of widely differing species. Christensen and C h a p m a n (1) observed them in interstitial cells of the a lbino ra t testis and report tha t they have also seen t hem in Sertoli cells of the same tissue. T h r o u ...

Lichen myxedematosus is a cutaneous mucinosis of idiopathic origin. According to Rongioletti’s classification, 2006, lichen myxedematosus is classified into three forms. The scleromyxedema or lichen myxedematosus sclerodermiform and generalized is a form of lichen myxedematosus characterized by numerous papules and areas of cutaneous hardening due to the deposition of mucin in association with ...

Most biofilms involved in catheter-associated urinary tract infections (CAUTIs) are polymicrobial, with disease causing (eg Escherichia coli) and atypical microorganisms (eg Delftia tsuruhatensis) frequently inhabiting the same catheter. Nevertheless, there is a lack of knowledge about the role of atypical microorganisms. Here, single and dual-species biofilms consisting of E. coli and atypical...

CUL7 and the p53-associated, PARkin-like cytoplasmic protein (PARC) were previously reported to form homodimers and heterodimers, the first demonstration of cullin dimerization. Although a CUL7-based SKP1/CUL1/F-box (SCF)-like complex has been observed, little is known about the existence of a PARC-based SCF-like complex and how PARC interacts with CUL7-based complexes. To further characterize ...

INTRODUCTION Cat scratch disease (CSD) is an acute infectious disease with benign course caused by the bacteria Bartonella henselae. Clinically, it is usually manifested as regional lymphadenopathy and mild infective syndrome. Rare forms of the disease which usually occur in immunocompromised presons are: encephalitis, transverse myelitis, neuroretinitis, granulomatosus conjunctivitis, arthriti...

Case Description- A pigeon with an abnormal mass on right wing was referred to the Veterinary Clinic of Shahid Bahonar University of Kerman. Treatment and Outcome- The mass was removed surgically and histopathologic examination was done.
