BACKGROUND Surgical site marking is one important cornerstone for the principles of safe surgery suggested by the WHO. Generally it is recommended that the attending surgeon performs the surgical site marking. Particularly in the case of same day surgery, this recommendation is almost not feasible. Therefore we systematically monitored, whether surgical site marking can be performed by trained ...

Last summer, AAAI sponsored a mobile robot competition in conjunction with the AAAI-92 conference in San Jose, California. Ten robots from across the country competed in the competition, with CARMEL from the University of Michigan finishing first. CARMEL is a Cybermotion K2A mobile platform with a ring of 24 sonar sensors and a single black and white CCD camera. For computing, CARMEL has three ...

The hypothalamic synthetic pathway of oxytocin (OT) involves the synthesis of carboxy-extended forms that serve as intermediate prohormones. We hypothesized that extended forms of OT are synthesized in the late-gestational rat uterus and that they compete for OT receptor binding. Parturition occurs only when the ratio of OT to its extended forms reaches a critical level. We have measured OT and...

G-protein coupled receptors (GPCR) tend to desensitize/internalize when exposed to excess agonist.Previously, we have supported the argument that in the case of the oxytocin receptor (OTR), excess agonist (oxytocin, OT) at birth could be implicated with behavioural disorders of the autistic spectrum. In this review, more recent evidence for this hypothesis is summarized, and it is juxtaposed ag...

The HPLC enantiomeric separation of 29 racemic bridged polycyclic compounds was examined on commercially available Chiralcel OD-H and Chiralpak OT(+) columns. The separations were evaluated under normal-phase mode (hexane containing mobile phase) for Chiralcel OD-H and under normal-phase as well as under reversed-phase mode (pure MeOH, temperature 5 degrees C) for Chiralpak OT(+). Almost all co...

It has long been believed across languages that the Agent-First strategy, a comprehension heuristic maps first noun onto agent role, is general cognitive bias which applies automatically and faithfully to children's comprehension. The present study asks how this strategy interplays with such grammatical cues as number of overt arguments presence case-marking in Korean, an SOV language by dedica...
