The time-dependent effect of transcranial direct current stimulation (tDCS) on working memory was investigated by applying anodal stimulation over the left prefrontal cortex. This single-blind, sham-controlled crossover study recruited 15 healthy participants. A three-back verbal working-memory task was performed before, during, and 30 min after 1 mA anodal(More)
BACKGROUND Tendinopathy (pain and tendon degeneration) is associated with repetitive use and mechanical overload. However, the etiology of tendinopathy remains unclear. Clarification of histologic and molecular changes of tendon to repetitive stress could provide better understanding of Achilles tendon disorders related to repetitive stress. (More)
BACKGROUND AND PURPOSE Elevation of serum cardiac troponin T (cTnT) is regarded as a specific marker of acute coronary syndrome. Serum cTnT can be increased in patients with acute ischemic stroke, but its clinical implications remain unclear. The aim of this study was to identify the relationships between elevated cTnT and stroke severity, location, and(More)
OBJECTIVE To determine the development of the human penis, and hence the cause of congenital anomalies, using an immunohistochemical analysis of fetal penile ontogeny. MATERIALS AND METHODS In 25 human fetal penile specimens (gestational age 8 to 23 weeks) various tissues were localized immunohistochemically using stains for alpha-actin (smooth muscle),(More)
The purpose of this study was to evaluate the effects of botulinum toxin A (BTX-A, Botox) dilution volume and post-injection exercise with electrical stimulation on muscle paralysis. We injected 10 units of BTX-A diluted with 0.1 ml (B1, n=8) or 0.5 ml (B5, n=8) normal saline into both gastrocnemius muscles of 16 New Zealand white rabbits; two controls(More)
BACKGROUND Liposuction provides further reduction of axillary sweating and malodor when combined with dermal curettage with sharp rasping cannulas. This aggressive approach is associated with relatively higher rate of hematoma formation when compared to the conventional simple liposuction. OBJECTIVE The aim of this prospective, randomized, controlled(More)
BACKGROUND AND AIMS Leukoaraiosis (LA) is associated with aging and vascular risk factors, and is a risk factor of intracerebral hemorrhage (ICH) after treatment with warfarin or thrombolytic treatment for ischemic stroke. In this study, we sought to examine whether LA is a predictor of outcome after spontaneous ICH. METHODS We retrospectively analyzed(More)
Subclinical hypothyroidism (SCH) is thought to have an influence on stroke outcomes. However, few reports demonstrate a favorable relationship between the two. We evaluated this association in acute ischemic stroke. From Jan 2005 to June 2008, 756 acute ischemic stroke patients were recruited within seven days of onset. The patients with overt(More)
Although progressive hemiparesis occurs frequently in acute ischemic stroke, the topography and mechanisms associated with progressive motor deficit (PMD) remain unclear. The aim of this study was to identify the differences in PMD according to lesion location and the presumed underlying pathogenesis in patients with lacunar motor syndrome. Consecutive(More)
OBJECTIVE To assess the effect of core strengthening exercises on Cobb angle and muscle activity in male college students with functional scoliosis. METHODS Static and dynamic back muscle activity were evaluated via surface electromyography (sEMG). A core exercise protocol comprising 18 exercises was performed three times/week for 10 weeks. Patients were(More)
