Genetic C677T and A1298C polymorphisms in 5,10-methylenetetrahydrofolate reductase (MTHFR) and levodopa therapy in Parkinson's disease (PD) may increase homocysteine (Hcy) level. We examined whether connecting both polymorphisms influences the effect of levodopa on Hcy. MTHFR genotypes and Hcy, vitamin B(12), and folate levels were determined in 48(More)
Circadian and sleep disturbances are common behavioural and psychological symptoms of dementia; circadian rhythm-related molecules may be altered in dementia patients. This study investigated the expression of the period 1 clock gene product (PER1), which is involved in circadian rhythms, and inducible nitric oxide synthase (iNOS), thought to generate(More)
Alzheimer's disease (AD) is the most common cause of dementias. Mild cognitive impairment (MCI) indicates the situation that a person has memory complaints and mild objective cognitive impairment but no evidence of dementia. Sleep disturbance, one of the behavioral and psychological symptoms of dementia (BPSD), frequently occurs in patients with AD or MCI.(More)
OBJECTIVES Diabetic neuropathic pain may be relieved by onabotulinumtoxinA (BoNT/A). However, whether BoNT/A changes sensory perception in neuropathic patients remains unknown. This study used a double-blind crossover design to explore the possible effect of BoNT/A on sensory perception. METHODS Eighteen patients with painful diabetic polyneuropathy(More)
The cantharidinimide derivatives, 5a-h, including sulfanilamides containing pyrimidyl, pyrazinyl, hydrogen, thiazolyl, and oxazolyl groups were synthesized. Modification of cantharidinimide by means of the reaction of activated aziridine ring opening led to the discovery of a novel class of antitumor compounds. The analogues 10i-k, 11l-n, 12o-p, and 16q-s(More)
BACKGROUND Parkinson disease (PD) is a neurodegenerative disease characterized by motor and nonmotor dysfunctions, which include sleep disturbances. Rapid eye movement (REM) sleep is associated with numerous physiologic changes such as memory consolidation. Compelling evidence suggests that nitric oxide (NO) is crucial to both sleep regulation and memory(More)
This study compared forward and backward gait between Parkinson's disease (PD) patients with poorer and better attention capabilities. PD and healthy control (HC) participants received a dual-stimuli attention task. The results were assessed using principal component analysis to quantify and rank attention capability. Accordingly, 22 PD and 42 HC subjects(More)
