Aging increases the co-incidence of Alzheimer's disease (AD) and type 2 diabetes (T2DM). However, the critical factors that contribute to the age-related increase in AD-T2DM comorbidity have yet to be clarified. In this study, aging effects and their relationship to AD-related pathology and T2DM as well as the underlying mechanisms of this process were(More)
BACKGROUND Mood disorder is a frequent complication of stroke. Comorbid depressive and anxiety disorders are very common, indicating that it is advisable to assess both disorders at the same time. The aim of the present study was to examine the prevalence of post-stroke depression (PSD) and poststroke anxiety (PSA) at baseline and to evaluate factors(More)
Metastatic gastric cancer is extremely rare and gastric metastasis from ovarian adenocarcinoma has rarely been reported. All of the previously reported metastatic lesions presented as an ulcerative lesions. We report a case of 49-year-old woman in which gastric metastasis from ovarian adenocarcinoma presented as a submucosal tumor without ulceration on(More)
Caspase cleavage of amyloid precursor protein (APP) has been reported to be important in amyloid beta protein (Aβ)-mediated neurotoxicity. However, the underlying mechanisms are not clearly understood. In this study, we explored the effect of caspase cleavage of APP on tau phosphorylation in relation to Aβ. We found that Asp664 cleavage of APP increased tau(More)
Osteoblasts are specialized mesenchymal cells that are responsible for bone formation. In this study, we examine the role of GATA4 in osteoblast differentiation. GATA4 was abundantly expressed in preosteoblast cells and gradually down-regulated during osteoblast differentiation. Overexpression of GATA4 in osteoblastic cells inhibited alkaline phosphatase(More)
We describe a patient with palatal tremor (PT) as a manifestation of focal seizure caused by acute cortical infarction. Brain MRI showed acute infarction in the left precentral gyrus without evidence of brainstem lesions or hypertrophy of the inferior olivary nucleus. We discuss the differences between our patient and previous reports of symptomatic PT and(More)
We describe an atypical case of Hirayama disease (HD) presenting as unilateral triceps atrophy. HD is juvenile muscular atrophy involving predominantly the seventh and eighth cervical, and the first thoracic spinal segments of the distal upper extremities. In contrast to typical HD, our patient presented with isolated triceps atrophy, innervated by the(More)
BACKGROUND Myasthenia gravis (MG) is occasionally aggravated by chronic infection, of which there are many kinds. CASE REPORT We report herein the case of a 56-year-old woman with MG aggravated by the activation of isolated mediastinal tuberculous lymphadenitis (MTL) during corticosteroid administration. The possibility of MTL had been disregarded in the(More)
BACKGROUND Pain and osteoporosis are common in Parkinson's disease (PD), and lower bone mineral density (BMD) or osteoporosis may be associated with an increased risk of reporting to have pain in the general population. The aim of this study was to determine whether there is an association between the pain subtypes and the BMD in patients with PD. METHODS(More)
Localized radiotherapy (RT) can cause immune dysfunction. Bojungikki-tang is known to restore immune function. We investigated the absolute counts and percentages of peripheral blood (PB) lymphocyte subtypes in end stage cancer patients before and after RT and after oral administration of Bojungikki-tang water extract (BJITE) and to evaluate the changes(More)
