BACKGROUND Deep brain stimulation (DBS) of the subthalamic nucleus is an effective treatment for advanced Parkinson disease (PD). However, achieving ideal outcomes by conventional programming can be difficult in some patients, resulting in suboptimal control of PD symptoms and stimulation-induced adverse effects. Interleaving stimulation (ILS) is a newer programming technique that can individua...

BACKGROUND Several meta-analyses have indicated that periodontal disease (PD) are related to cardiovascular diseases (CVDs). However, the association between PD and myocardial infarction (MI) remains controversial. Here we aimed to assess the association between PD and MI by meta-analysis of observational studies. METHODS PubMed, EMBASE and the Cochrane Library were searched through July, 201...

this paper focused on a novel method of electroless plating ruthenium (ru) on solid or porous substrates like porous stainless steel (pss) discs or ceramic tubes. a novel complexing plating bath of ru was developed. it is proven that ru can be deposited directly on these substrates by the bath at a temperature of 328 k and strong alkaline environment. tga, sem, edx and xrd confirmed the success...

Palladium has attracted significant attention as a catalyst or co-catalyst for many electrochemical reactions in energy conversion devices. We have studied stability of commercial Pd/C sample an acidic electrolyte by exposing it to accelerated stress test (AST) mimic potential spikes fuel cells and electrolyzers during start/stop events. AST consisted extensive rapid cycling (5000 cycles, 1 V/s...

normal 0 false false false en-us x-none ar-sa background: t he study on transcranial sonocraphy (tcs) as a diagnostic test for parkinson’s disease (pd) has been neglected in some hospitals. the current study was conducted as the first study to investigate the utility of tcs for diagnosis of pd and its ability to distinguish pd from essential tremor (et) in an iranian population. materials and m...

    Background: Parkinson’s disease (PD) is a progressive neurological disorder and many PD patients experience some type of voice and speech disorders during the course of illness. In this study, the aim was to investigate the effect of Lee Silverman voice treatment (LSVT) on improving voice difficulties in patients with mild PD using voice handicap index (VHI).    Methods: This interventiona...

   Adsorption of OH on the PdxCu3-x(x=0-3) small clusters is investigated by density functional theory calculations. It is found that OH adsorbs in three possible modes including on top, bridge and hollow sites while the structures where OH bridges between two atoms are the most stable structures. The Pd-Pd, Pd-Cu and Cu-Cu equilibrium distances for most of the systems...

Objective: Parkinson's disease (PD) is one of the most common neurodegenerative disorders which is characterized by tremor, rigidity, bradykinesia and postural disturbances. Studies indicate that grape juice and exercise may have beneficial effects on neurodegenerative disorders. Therefore, in the present study, we evaluated the effects of red grape juice (GJ) together with treadmill running on...
