OBJECTIVE This study investigated the effects of resveratrol, a natural polyphenol with neuroprotective properties, on retinal neuronal cell death mediated by diabetes-induced activation of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII). RESEARCH DESIGN AND METHODS Diabetes was induced in C57BL/6 mice by five consecutive intraperitoneal injections(More)
OBJECTIVE Protein kinase C (PKC)-delta, an upstream regulator of the Akt survival pathway, contributes to cellular dysfunction in the pathogenesis of diabetes. Herein, we examined the role of PKC-delta in neuronal apoptosis through Akt in the retinas of diabetic rats. RESEARCH DESIGN AND METHODS We used retinas from 24- and 35-week-old male Otsuka(More)
A 51-year-old man with a 1-month history of lower back pain and radiating pain visited to our pain clinic. A magnetic resonance imaging (MRI) scan demonstrated a cyst like mass at the level of the L4-5 interspace and compression of the thecal sac and the nerve root on the right side. We performed percutaneous needle aspiration of the lumbar zygapophyseal(More)
A 39-year-old female was suffering from cold-induced Raynaud's attacks in both hands and feet, with symptoms being most severe in her left foot. The patient did not respond to medical treatments and was referred to our department of pain medicine. We performed sequential bipolar radiofrequency lumbar sympathectomy to the patient, which offered a long(More)
PURPOSE The purpose of this study was to evaluate the functional outcomes of the over-tensioning technique compared with those of the standard tensioning technique in the transfer of extensor indicis proprius (EIP) to extensor pollicis longus (EPL) for the chronic rupture of the thumb extensor. METHODS Data were collected from patients who underwent(More)
provided the original work is properly cited. CC The exact origins of pain and neurologic findings in patients with herniated discs are not completely understood. Mechanical compression and inflammatory processes are the most well known possible causes of radicular pain. Generally, clinical symptoms correspond to the findings on radiologic studies. But in(More)

A 54-year-old female was suffering from cold-induced Raynaud's attacks in her both hands with symptoms most severe in her left hand. As the patient did not respond to previous medical treatments and endoscopic thoracic sympathectomy, we performed percutaneous bipolar radiofrequency thoracic sympathicotomy at the left T3 vertebral level. After the procedure,(More)
A 68-year-old woman suffered from lower back and radiating pain on her right buttock and posterior calf. Axial magnetic resonance imaging showed a 7 × 7 mm nodular lesion (T1 and, T2 low signal intensity) at the epidural space between the L5-S1 level and computed tomography revealed it was an epidural gas cyst. The authors performed an epidural block and(More)
