Abstract
Seizures affect each patient differently, so personalization is a vital part of developing a reliable nonEEG based seizure detection system. This personalization must be done while the patient is undergoing video EEG monitoring in an epilepsy monitoring unit (EMU) because seizure detection by EEG is considered to be the ground truth. We propose the use of confidence interval analysis for determining how many seizures must be captured from a patient before we can reliably personalize such a seizure detection system for him/her. Our analysis indicates that 6 to 8 seizures are required. In addition, we create seizure likelihood tables for future use by said system by comparing the number of times a prespecified biosignal activity level is induced by seizure to the total number of occurrences of that level of activity. We focus on complex partial seizures in this paper because they are more difficult to detect than are generalized seizures.

Abstract
Single signal seizure detection algorithms suffer from high false positive rates. We have found a set of signals which can be easily monitored by a wristworn device and which produce a distinctive pattern during seizure for patients in an epilepsy monitoring unit (EMU). This pattern is much less likely to be reproduced by nonseizure events in the patient's daily life than are changes in heart rate alone. We collected 108 hours of data from three EMU patients who suffered a combined total of seven seizures, then developed a time series analysis/pattern recognition based algorithm which distinguishes the seizures from nonseizure events with 100% accuracy.

Abstract
EEG based monitoring for the purpose of assessing a patient's neurological status is conspicuous and uncomfortable at best. We are analyzing a set of physiological signals that may be monitored comfortably by a wrist worn device. We have found that these signals and machine based classification allows us to accurately discriminate among four stress states of individuals. Further, we have found a clear change in these signals during the 70 minutes preceding a single convulsive epileptic seizure. Our classification accuracy on all data has been greater than 90% to date.

Abstract
Optimization of pyrazinoindolone inhibitors of MAPKAP-K2 (MK2) provides a reasonable balance of cellular potency and physicochemical properties. Mechanistic studies support the inhibition of MK2 which is responsible for the sub-micromolar cellular efficacy.

Abstract
We report a case of radial palsy of the Frohse arcade type with complete motor deficit due to compression of the posterior interosseous nerve by a fibrous bands in the radial tunnel proximal to the arcade. Simple neurolysis of the posterior interosseous nerve with section of the compressing fibrous bands allowed complete recovery of the motor deficit. We discuss the surgical technique based on our experience with this case and earlier reports in the literature.

Abstract
Higher self-efficacy (SE) is associated with lower pain ratings in chronic pain patients, although longer experience with chronic pain leads to lower SE scores. Self-efficacy in pain patients does not appear to be clearly related to sex or age, however. This study investigated the effects of gender, age, length of pain experience (chronicity) on SE and pain ratings. Archival data from the records of 187 patient's charts were evaluated for demographic information, chronicity, pain ratings and SE. Analyses found a significant inverse relationship between SE and pain ratings (r = -.22) and lower SE for young adult patients. Results support the conclusion that enhanced SE is an important psychosocial intervention in the treatment of chronic pain patients.

Abstract
Two experiments were conducted to test the proposal that laughter is a pain antagonist. In Experiment I, thresholds for pressure-induced discomfort of 20 male and 20 female subjects were measured after each subject listened to a 20-min-long laughter-inducing, relaxation-inducing, or dull-narrative audio tape or no tape. Discomfort thresholds were higher for subjects in the laughter- and the relaxation-inducing conditions. In Experiment II, 40 female subjects were matched for pressure-induced discomfort thresholds. Their discomfort thresholds were measured after they listened to a laughter-inducing, interesting narrative, or uninteresting narrative audio tape, completed a multiplication task, or experienced no intervention. Discomfort thresholds increased for subjects in the laughter-inducing condition. Laughter, and not simply distraction, reduces discomfort sensitivity, suggesting that laughter has potential as an intervention strategy for the reduction of clinical discomfort.

Abstract
Two experiments examining spontaneous alternation in young white Leghorn chicks are reported. In Experiment I chicks (20 per group) run in a T-maze for 4 trials to social reward displayed alternation of responses, whereas nonrewarded chicks did not alternate. In Experiment II socially rewarded chicks (20 per group) again showed reliable alternation of responses whereas food, water, and nonrewarded chicks did not alternate. These data support the premise that spontaneous alternation behavior has some phyletic generality under optimum conditions, although the mechanisms which control it may differ across species.
