Abstract:
Excitatory neurotransmission at the N-methyl-D-aspartate (NMDA) receptor is selectively blocked by 2-amino-7-phosphonoheptanoate acid (2-APH). Acute focal microinjection of 2-APH into the rat hippocampus partially protects against cytopathology developing in selectively vulnerable neurons after 30 min of ischaemia and 2 h of reperfusion. We show that this protective action of 2-APH does not involve alterations in local cerebral blood flow (CBF). Intermediate cytopathology and long-term neuronal survival has been assessed in rats receiving focal injections of (±) 2-APH. 20 μg in 1 μl, into one

Abstract:
The rate of ischemic brain injury varies with the brain region, requiring only hours in striatum but days in hippocampus. Such maturation implies the existence of endogenous neuroprotective mechanisms. Adenosine is an endogenous neuroprotectant regulated by adenosine kinase (ADK). To investigate, whether adenosine might play a role in protecting the hippocampus after focal ischemia, we subjected transgenic mice, which overexpress ADK in hippocampal neurons (Adk-tg mice) to transient middle cerebral artery occlusion (MCAO). Although the hippocampus of wild-type (wt) mice was consistently spared

He, Qin, Rubin Wang, and Xiaochuan Pan. "This paper presents a two-dimensional histogram shifting technique for reversible data hiding algorithm. In order to avoid the distortion drift caused by hiding data into stereo H.264 video, we choose arbitrary embeddable blocks from 4×4 quantized discrete cosine transform luminance blocks which will not affect their adjacent blocks. Two coefficients in each embeddable block are chosen as a hiding coefficient pair. The selected coefficient pairs are classified into different sets on the basis of their values. Data could be hidden according to the set which the value of the coefficient pair belongs to. When the value of one coefficient may be changed by adding or subtracting 1, two data bits could be hidden by using the proposed method, whereas only one data bit could be embedded by employing the conventional histogram shifting. Experiments show that this two-dimensional histogram shifting method can be used to improve the hiding performance."
