AIM To compare the effectiveness of landmark-guided local injections and ultrasonography (USG) guided injections for shoulder pain. METHODS A total 60 consecutive patients with shoulder pain due to soft tissue disorders was enrolled, and randomly assigned to receive triamcinolone (40 mg) either by landmark-guided (LMG, n=30) or USG guided (n=30)(More)
Ankylosing spondylitis (AS) is a prototype of seronegative arthropathy frequently affecting young men. In these patients systemic complications may develop in addition to joint involvement. Behqet's disease (BD) is also a multisystem disorder. The coexistence of these two conditions is rare. We describe a patient who has fulfilled diagnostic criteria for(More)
New blood vessel formation (angiogenesis) is one of the most important processes required for functional tissue formation. Induction of angiogenesis is usually triggered by growth factors released by cells. Glycosaminoglycans (e.g., heparan sulphates) in the extracellular matrix aid in proper functioning of these growth factors. Therefore, exogeneous(More)
There are some reports that classical neuroleptics may lead to osteoporosis or reduced bone mineral density (BMD). However, there is no adequate information about the effects of atypical neuroleptics on BMD. The aim of this study was to measure BMD in schizophrenic patients taking classical and atypical neuroleptics, compared to healthy controls.(More)
The supramolecular design of bioactive artificial extracellular matrices to control cell behavior is of critical importance in cell therapies and cell assays. Most previous work in this area has focused on polymers or monolayers which preclude control of signal density and accessibility in the nanoscale filamentous environment of natural matrices. We have(More)
Metal-based scaffolds such as stents are the most preferred treatment methods for coronary artery disease. However, impaired endothelialization on the luminal surface of the stents is a major limitation occasionally leading to catastrophic consequences in the long term. Coating the stent surface with relevant bioactive molecules is considered to aid in(More)
Scaffold design plays a crucial role in developing graft-based regenerative strategies, especially when intended to be used in a highly ordered nerve tissue. Here we describe a hybrid matrix approach, which combines the structural properties of collagen (type I) with the epitope-presenting ability of peptide amphiphile (PA) nanofibers. Self-assembly of PA(More)
Mineralized biological materials such as shells, skeleton, and teeth experience biomineralization. Biomimetic materials exploit the biomineralization process to form functional organic-inorganic hybrid nanostructures. In this work, we mimicked the biomineralization process by the de novo design of an amyloid-like peptide that self-assembles into nanofibers.(More)
A 24 year-old male who presented with palpitations and presyncopal attacks had monomorphic ventricular tachycardia and a well-defined huge mass within the inferoposterior wall of the left ventricle proved by transthoracic echocardiography. The mass was completely resected and shown to be proliferative angiomatosis by histopathologic examination. This is the(More)
AIM The aim of this study was to estimate the prevalence of rheumatoid arthritis (RA) in the eastern Black Sea region of Turkey. METHOD The study was carried out between March 2003 and March 2005 by the Karadeniz Technical University Medical Faculty Department of Physical Medicine and Rehabilitation in the urban area in the eastern Black Sea region of(More)
