It has been documented that stress or glucocorticoids have conflicting effects on memory under different conditions. However, it is not fully understood why stress can either impair or enhance memory. Here, we have examined the performance of six age groups of Wistar rats in a water maze spatial task to evaluate the effects of stress under different(More)
BACKGROUND AND PURPOSE Previous studies suggested that the overall burden of prior infections contributes to cardiovascular diseases and stroke. In the present study, the association between infectious burden (IB) and Alzheimer's disease (AD) was examined. METHODS Antibody titers to common infectious pathogens including cytomegalovirus (CMV), herpes(More)
In Alzheimer's disease (AD), neurodegenerative signals such as amyloid-beta (Aβ) and the precursors of neurotrophins, outbalance neurotrophic signals, causing synaptic dysfunction and neurodegeneration. The neurotrophin receptor p75 (p75NTR) is a receptor of Aβ and mediates Aβ-induced neurodegenerative signals. The shedding of its ectodomain from the cell(More)
BACKGROUND Extent of atherosclerosis measured by amount of coronary artery calcium (CAC) in computed tomography (CT) has been traditionally assessed using thresholded scoring methods, such as the Agatston score (AS). These thresholded scores have value in clinical prediction, but important information might exist below the threshold, which would have(More)
current density (J), voltage (V), and luminance (L) characteristics were measured using an HP4145 semiconductor parameter ana-lyzer, with the quantum efficiency obtained by placing and centering the OLEDs onto the surface of a calibrated Si photodiode with a large diameter. Photolithography has been the main technology for integrated circuit (IC)(More)
OBJECTIVE To quantitatively analyze the changes of facial symmetry and temporomandibular joint structure at different periods after intraoral condylectomy combined with orthognathic surgery, and to evaluate the long-term stability after the operation. METHODS Spiral CT data of 10 cases treated by intraoral condylectomy combined with orthognathic surgery(More)
Key Points: • Preliminary breakdown pulses can be reproduced by simulated channel extension • Channel heating and corona sheath formation are crucial to proper pulse shape • Extension processes and channel orientation significantly affect observations (2015), Time domain simulations of preliminary breakdown pulses in natural lightning, J. Geo-phys. This is(More)
The experiment were performed on model rabbits injected with large dosage of Dexamethasone (DXM) for 5 days. Reinforcing manipulation (RIM), reducing manipulation (RDM), and electric stimulation (ES) were respectively used to puncture Zusanli (ST 36) points for 5 days to observe the change on temperature, body weight, corticosterone assay, testosterone(More)
