Wireless body area networks (WBANs) provide communication services in the vicinity of the human body. Since the WBAN services consists of both medical and consumer electronics (CE) applications, MAC protocols in the WBAN should be designed considering flexibility and different characteristics between medical and CE applications. In this paper, we propose a(More)
AIMS Parkinson's disease is a debilitating neurodegenerative disorder characterized by the gradual loss of dopaminergic neurons. We investigated the effects of treadmill exercise on dopaminergic neuronal loss and microglial activation using 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine/probenecid (MPTP/P)-induced Parkinson's disease mice. MAIN METHODS(More)
OBJECTIVE To compare the efficacy of intrathecal methotrexate single therapy with three-drug combination therapy in patients with leptomeningeal carcinomatosis. METHODS Fifty-five patients who had pathologically proven leptomeningeal carcinomatosis of a solid tumor were evaluated in terms of pathological response. Group M (n = 29) received methotrexate 15(More)
Diabetes is a metabolic disorder, and it is considered as a major risk factor for Alzheimer's disease (AD). In the present study, we evaluated whether treadmill exercise ameliorates progression of AD in relation with glycogen synthase kinase-3β (GSK-3β) activity using streptozotocin (STZ)-induced diabetic rats. For this study, step-down avoidance task,(More)
—A wireless body area network (WBAN) is constructed in the vicinity of a human body and provides various services for both medical and non-medical services. In order to provide monitoring services for medical devices, routing algorithms for wireless sensor networks (WSN) have been considered for WBANs. However, unlike WSNs, which consist of homogeneous(More)
Apoptosis occurring secondary to spinal cord injury (SCI) causes further neural damage and functional loss. In this study, a rat model was used to investigate the effect of treadmill exercise on SCI-induced apoptosis and expression of neurotrophic factors. To produce SCI, a contusion injury (10 g x 25 mm) was applied subsequent to laminectomy at the T9-T10(More)
We conducted a phase 3 randomized trial comparing 2 different doses of daunorubicin as induction chemotherapy in young adults (60 years of age or younger) with acute myeloid leukemia (AML). Of 383 patients who were analyzed, 189 received standard-dose daunorubicin (SD-DN, 45 mg/m² per day times 3 days) and 194 received high-dose daunorubicin (HD-DN, 90(More)
Data routing in wireless sensor networks must be energy-efficient because tiny sensor nodes have limited power. A cluster-based hierarchical routing is known to be more efficient than a flat routing because only cluster-heads communicate with a sink node. Existing hierarchical routings, however, assume unrealistically large radio transmission ranges for(More)
SUMMARY WBANs provide communication services in the vicinity of the human body. Since WBANs utilize both MICS frequency band for implant medical applications and ISM frequency band for medical and consumer electronics (CE) applications, MAC protocols in WBAN should be designed considering flexibility between medical and CE applications. In this letter, we(More)
