The expression and significance of tyrosine hydroxylase in the brain tissue of Parkinsons disease rats
The expression and significance of tyrosine hydroxylase (TH) in brain tissue of rats with Parkinson's disease (PD) were explored and analyzed. A total of 120 clean-grade and healthy adult Wistar rats weighing 180-240 g were randomly divided equally into four groups according to the random number table method. Rats were sacrificed before and after the model establishment for 3, 6 or 8 weeks. The...
متن کاملBrain aging in dogs: parallels with human brain aging and Alzheimer's disease.
Differentiating normal from pathologic aging is a challenge to veterinarians treating geriatric patients and to clinicians diagnosing Alzheimer's disease. Part of the difficulty stems from the lack of a biological marker. Dogs and humans develop similar cognitive dysfunction with age, and a subset of individuals develop severe impairments. Similar neuropathology also develops in the brains of e...
متن کاملDeep Brain Stimulation of the Subthalamic Nucleus Improves Lexical Switching in Parkinsons Disease Patients
OBJECTIVE Reduced verbal fluency (VF) has been reported in patients with Parkinson's disease (PD), especially those treated by Deep Brain Stimulation of the subthalamic nucleus (STN DBS). To delineate the nature of this dysfunction we aimed at identifying the particular VF-related operations modified by STN DBS. METHOD Eleven PD patients performed VF tasks in their STN DBS ON and OFF conditio...
متن کاملBayesian Networks Modeling for Brain Effective Connectivity in Parkinsons Disease ( PD )
Research derived from non-invasive brain imaging modalities has been used to explore the spatial and temporal organization of the neural systems supporting human behavior and causing brain disorders. Imaging modalities of interest include positron emission tomography, event-related potentials, electro-and magnetoencephalography, and magnetic resonance imaging (MRI). In this talk, we will presen...
متن کاملParkinsons Disease Classification using Neural Network and Feature Selection
In this study, the Multi-Layer Perceptron (MLP)with Back-Propagation learning algorithm are used to classify to effective diagnosis Parkinsons disease(PD).It’s a challenging problem for medical community.Typically characterized by tremor, PD occurs due to the loss of dopamine in the brains thalamic region that results in involuntary or oscillatory movement in the body. A feature selection algor...
