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...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
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...
Objectives: In the early stages, most Parkinson’s patients display some degrees of voice and speech disorders. Speech disorders can negatively affect social interactions and human life, thus treatment plans for the disorders in the early stages might be further beneficial than the late stages. Therefore, we aimed to investigate on the effect of an intervention on Persian patients with early mil...
چگالی چیدمان (pd) اختلاط سنگدانه ها یکی از پارامترهای مهم و تعیین کننده در طرح اختلاط بتن می باشد. هر چه مقدار pd اختلاط سنگدانه ها بیشتر باشد، مقدار فضای خالی کمتری در بین سنگدانه ها وجود دارد و لذا به مقدار سیمان کمتری جهت پر نمودن فضاهای خالی احتیاج می باشد. در صورتی که مقدار خمیر سیمان در بتن ثابت باشد، افزایش میزان pd، منجر به افزایش کارایی در یک نسبت آب به سیمان (w/c) ثابت می شود و هم چنی...
در این پروژه، روش سنتز تعدادی از کمپلکس های تک هسته ای اورتوپالادیت حاوی لیگاندهای تک دندانه و دو دندانه با استفاده از کمپلکس دو هسته ای تری فنیل فسفیت اولیه ارایه شده است. طی این مطالعه، کمپلکس دو هسته ای اورتوپالادیت 1)) [pd(?-cl)p(oph)2(oc6h4)]2 از رفلاکس pdcl2 با pdcl2[p(oph)3]2 در حلال تولوئن به مدت پنج ساعت بدست آمده است. از واکنش این کمپلکس با لیگاندهای تک دندانه تری فنیل فسفین (pph3)، 2...
Parkinson’s Disease (PD) is a chronic, progressive, neurodegenerative disorder with motor and non-motor signs and symptoms. PD is caused by idiopathic degeneration of dopamine-producing cells in the substantia nigra, located in the midbrain. Recently, Trace elements have been recognized to play an important role in the development of Parkinson’s disease (PD). The aim of this review ...
تأثیر سه الگوی تمرینی روی قدرت عضلانی موشهای صحرایی مبتلا به پارکینسون القایی با 6-هیدروکسی دوپامین
Background and Aims: Parkinson Disease (PD) as a second neurodegenerative disease has grown in developed and industrial countries due to high life span, and in Iran it is considered an important neurodegenerative disease either. The drug therapy of PD must be paralleled with other treatments because the age of PD occurrence has decreased in recent decades and disturbed active population life st...
