OBJECTIVE The chronic inflammation associated with atherosclerosis is caused by lipid deposition followed by leukocyte recruitment to the arterial wall. We previously showed that the hematopoietic cell-specific adaptor protein Cas- and Hef1-associated signal transducer hematopoietic isoform (Chat-H)/SHEP1 regulated lymphocyte adhesion and migration. In this study, we analyzed the role of Chat-H...

The traditional analysis of Internet chat room discussions places a resource burden on the intelligence community because of the time required to monitor thousands of continuous chat sessions. Chat rooms are used to discuss virtually any subject, including computer hacking and bomb making, creating a virtual sanctuary for criminals to collaborate. Given the upsurge of interest in homeland secur...

Chat services that provide real-time help for customers have been adopted widely and rapidly on many websites in the past few years. Our paper investigates online live chat customer services from two perspectives: media choice between chat service and web e-mail, and media use of chat service analyzed from the perspectives of characteristics, interactivity and socioemotional content. We collect...

Neuroprotective effect of deprenyl on motoneurons of spinal cord after axotomy of peripheral nerves such as sciatic has been well established. Deprenyl is an inhibitor of monoamine oxidase type-B (MAO-B). The main function of this agent is the release of neurotransmitters from pre-synaptic terminals. Acetylcholine is a neurotransmitter that is synthesized by choline acetyltransferase (ChAT) and...

This paper investigates the use of chat by Greek students. An appropriate questionnaire was developed. Among others, the questions attempted to identify the users’ preferences regarding chat rooms and discussion subjects, their expectations for advanced chat features, as well as the relation between chat and normal life. The questionnaire was

CHAT ooers an alternative to SLG-WAM for implementing the suspension and resumption of consumers: unlike SLG-WAM, it does not use freeze registers nor a complicated trail to preserve their execution environments. CHAT also limits the amount of copying of CAT, which was previously put forward as an alternative to SLG-WAM. Although experimental results show that in practice CHAT is competitive wi...

The cholinergic system plays important roles in neurotransmission in both the peripheral and central nervous systems. The cholinergic neurotransmitter acetylcholine is synthesized by choline acetyltransferase (ChAT) and its action terminated by acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). The predominance of AChE has focused much attention on understanding the relationship of ...

Using a monoclonal antibody against choline acetyltransferase (ChAT), we have examined the distribution of cholinergic neurons in the rat dentate gyrus during development. ChAT-positive neurons were occasionally detected in the hilus on postnatal day 2 (P2). There was a transient abrupt increase in the number and density of ChAT-positive neurons between P15 and P20 and then a decline to the adu...
