Identification of learning-induced changes in protein networks in the hippocampi of a mouse model of Alzheimer's disease

Memory loss is the most profound clinical manifestation in Alzheimer's disease (AD); however, the molecular mechanisms underlying these deficits are poorly understood. Identification of the molecular pathways involved in the onset of cognitive deficits may lead to the identification of key events in the pathogenesis of AD. Using isobaric tags for relative and absolute quantitation (iTRAQ) and p...

History of Medical Sciences in Iran

The practice and study of medicine in Persia has a long and prolific history. The ancient Iranian medicine was combined by different medical traditions from Mesopotamia, Egypt, India, China and Greece for more than 4000 years and merged to form what became the nucleus and foundation of medical practice in the European countries in the 13th century. The Iranian academic centers like Jundishapur ...

The medial septum mediates impairment of prepulse inhibition of acoustic startle induced by a hippocampal seizure or phencyclidine.

The involvement of the septohippocampal system on the impaired sensorimotor gating induced by phencyclidine (PCP) or by an electrically induced hippocampal seizure was examined in behaving rats. An impaired sensorimotor gating, measured by prepulse inhibition (PPI) of the acoustic startle response, was observed following a hippocampal afterdischarge (AD) or systemic injection of PCP and was acc...

EEG Amplitude Modulation Analysis for Semi-Automated Diagnosis of Alzheimer's Disease

Recent experimental evidence has suggested a neuromodulatory deficit in Alzheimer’s disease (AD). In this paper, we present a new electroencephalogram (EEG) based metric to quantitatively characterize neuromodulatory activity. More specifically, the short-term EEG amplitude modulation rate-of-change (i.e., modulation frequency) is computed for five EEG subband signals. To test the performance o...
