Introduction: Epistaxis is one of the most common medical emergencies, making the management of posterior epistaxis a challenging problem for the ear, nose, and throat (ENT) surgeon. In the cases of conservative management failure, ligation of the major arteries or percutaneous embolization of the maxillary artery is performed routinely in most units, but rates of failure and complications are ...

Thirty-one Cephalosporin compounds were modeled using the multivariate image analysis and applied to the quantitative structure activity relationship (MIA-QSAR) approach. The acid dissociation constants (pKa) of cephalosporins play a fundamental role in the mechanism of activity of cephalosporins. The antimicrobial activity of cephalosporins was related to their first pKa by different models. B...

Protein A (SpA) is a component of the cell wall of Slop,lylococcus aureers. SpA is unique in that it combines with the Fc portion of immunolgobulins from many speciesi,2) and has been used in immunochemical studies3,`>. Another distinctive f ature of SpA is its potent mitogenic activity on lymphocytes from several species, including hurnans5,iO}. SpA also exerts a mitogenic activity on both T a...

COP1 (for CONSTITUTIVELY PHOTOMORPHOGENIC1) and the four partially redundant SPA (for SUPPRESSOR OF PHYA) proteins work in concert to repress photomorphogenesis in Arabidopsis thaliana by targeting key transcription factors and phytochrome A for degradation via the 26S proteasome. Here, we report a detailed biochemical characterization of the SPA-COP1 complexes. The four endogenous SPA proteins...

The purpose of this study was to examine predictors of social physique anxiety (SPA). SPA, self-esteem, body-esteem, public body consciousness (PBC) and percent body fat (%BF) were assessed with elite female youth athletes (N = 68) competing in either figure skating, soccer or gymnastics. Stepwise multiple regression analyses, controlling for BF%, accounted for 59% of the variance in SPA. Self-...

The age-old spa concept is no less valuable today than it was during the time of Julius Caesar. Over the centuries, there have been many iterations of the concept of the spa. The most recent is the medical spa, which has become the fastest-growing segment of the spa industry. Many physicians including dermatologists wish to incorporate a medical spa into their practices. This article discusses ...

Branching quantifiers were first introduced by L. Henkin in his 1959 paper 'Some Remarks on Infinitely Long Formulas'. By 'branching quantifiers' Henkin meant a new, non-linearly structured quantifier-prefix whose discovery was triggered by the problem of interpreting infinitistic formulas of a certain form. 1 The branching (or partially-ordered) quantifier-prefix is, however, not essentially i...

Correspondence to Dr Marloes van Onna; [email protected] ABSTRACT Objectives: To evaluate the practice performance of general practitioners (GPs) and GP residents in recognising and referring patients suspected for having axial or peripheral spondyloarthritis (SpA), and to investigate the influence of education on this performance. Methods: GP (residents) were visited in two rounds by standard...

Considering the relation between synovial inflammation and global disease activity in rheumatoid arthritis (RA) and the distinct but heterogeneous histology of spondyloarthropathy (SpA) synovitis, the present study analyzed whether histopathological features of synovium reflect specific phenotypes and/or global disease activity in SpA. Synovial biopsies obtained from 99 SpA and 86 RA patients w...
