Systematic human pathological background to brain tumor radiosurgery explaining biological and pathophysiological effects of focused irradiation barely exists. The goal of this study was to explore histopathological changes evoked by single high-dose irradiation in a set of different brain tumors following Gamma Knife radiosurgery (GKRS). Light microscopy revealed that GKRS evokes degenerative ...

A clinical and radiological study of upper and lower limb joints was carried out on 25 experienced weight-lifters to identify the extent of degenerative joint disease (Osteoarthrosis) produced by this sport. Although significant degenerative changes were found in five lifters (20%). This figure is not greater than that found in the general population within the age group studied. There were mor...

SHED (stem cells from human exfoliated deciduous teeth) represent a population of postnatal stem cells capable of extensive proliferation and multipotential differentiation. Primary teeth may be an ideal source of postnatal stem cells to regenerate tooth structures and bone, and possibly to treat neural tissue injury or degenerative diseases. SHED are highly proliferative cells derived from an ...

Automated blood sampling through a vascular catheter is a frequently utilized technique in laboratory mice. The potential immunological and physiological implications associated with this technique have, however, not been investigated in detail. The present study compared plasma levels of the cytokines IL-1β, IL-2, IL-6, IL-10, IL-17A, GM-CSF, IFN-γ and TNF-α in male NMRI mice that had been sub...

Sporadic inclusion body myositis (IBM) is the most common idiopathic inflammatory myopathy (IIM) after age 50 years. It presents with chronic insidious proximal leg and distal arm asymmetric muscle weakness. Despite similarities with polymyositis (PM), it is likely that IBM is primarily a degenerative disorder rather than inflammatory muscle disease. IBM is associated with a modest degree of cr...
