AIM OF THE STUDY SuHeXiang Wan (SHXW) is a Chinese traditional medicinal prescription that consists of 15 crude herbs. SHXW has been used to treat central nervous depression, seizures, infantile convulsion and stroke, and its essential oil has been shown to have anticonvulsant and antioxidative activity. The goal of this study was to investigate the(More)
The metastasis suppressor KAI1/CD82 has been implicated in various cellular processes; however, its function in development is not fully understood. Here, we generated and characterized mutants of Tsp66E and Tsp74F, which are Drosophila homologues of KAI1/CD82 and Tspan11, respectively. These mutants exhibited egg elongation defects along with disturbed(More)
DJ-1, a Parkinson's disease (PD)-associated gene, has been shown to protect against oxidative stress in Drosophila. However, the molecular mechanism underlying oxidative stress-induced phenotypes, including apoptosis, locomotive defects, and lethality, in DJ-1-deficient flies is not fully understood. Here we showed that Daxx-like protein (DLP), a Drosophila(More)
Hempseed is rich in polyunsaturated fatty acids (PUFAs), which have potential as therapeutic compounds for the treatment of neurodegenerative and cardiovascular disease. However, the effect of hempseed meal (HSM) intake on the animal models of these diseases has yet to be elucidated. In this study, we assessed the effects of the intake of HSM and PUFAs on(More)
Amyloid-β-42 (Aβ42) has been implicated in the pathogenesis of Alzheimer's disease (AD). Neuronal Aβ42 expression induces apoptosis and decreases survival and locomotive activity in Drosophila. However, the mechanism by which Aβ42 induces these neuronal impairments is unclear. In this study, we investigated the underlying pathway in theses impairments. JNK(More)
[Purpose] We investigated how diaphragm respiration exercises can affect pulmonary function in long-term male smokers in their twenties. [Subjects and Methods] Twenty-eight healthy males between 20 and 29 years of age were randomly divided into an experimental and a control group (14 members each). The experiment was conducted during 30 min sessions, 3(More)
SuHeXiang Wan (SHXW), a Chinese traditional medicine, has been used to treat infantile convulsions, seizures and strokes. Previously, we reported that modified SHXW, called KSOP1009, suppressed the hyper-activation of c-Jun N-terminal kinase (JNK) and Alzheimer's disease (AD)-like phenotypes in amyloid-β42 (Aβ42)-expressing Drosophila AD models. In the(More)
Periodically polarity inverted (PPI) ZnO templates were fabricated using molecular beam epitaxy by employing MgO buffer layers. The polarity of ZnO film was controlled by the transformation of crystal structure from hexagonal to rocksalt due to the thickness of the MgO buffer layers. The polarity of ZnO in the PPI template was confirmed by AFM and PRM(More)
Expression of the Down syndrome critical region 1 (DSCR1) protein, an inhibitor of the Ca(2+)-dependent phosphatase calcineurin, is elevated in the brains of individuals with Down syndrome (DS) or Alzheimer's disease (AD). Although increased levels of DSCR1 were often observed to be deleterious to neuronal health, its beneficial effects against AD(More)
