To assess learning abilities during human NREM sleep stages, five subjects underwent simple classical conditioning during stages 2-4 using heart rate (HR) as a measure. Results show (a) significant conditioning effect was observed during slow wave sleep (SWS; stage 3 + 4) but not during stage 2; (b) some evidence was obtained to support the view that(More)
A 35-year-old woman presented with a non-functioning pituitary adenoma manifesting as amenorrhea and impaired visual acuity in 1984. The tumor was grossly totally resected through a right frontotemporal craniotomy. The patient underwent surgery for three recurrences in the next 5 years. She was treated with gamma knife surgery for the residual tumor in(More)
We evaluated psychiatric care in terms of the relationship between patient outcome (length of stay, Global Assessment of Functioning (GAF) at discharge, GAF difference, and GAF change per day) and psychiatrist characteristics (gender and years in psychiatric practice) in patients with schizophrenia, schizotypal, or delusional disorders (ICD-10 codes(More)
We evaluated psychiatric care in terms of relationships between patient characteristics and a comprehensive measurement of psychiatric outcomes among inpatients with lengths of stay (LOSs) of 90 days or fewer in a psychiatric hospital in Japan. The sample consisted of inpatients discharged from an acute care psychiatric hospital between September 1 and(More)
Generally, cancer tissue is palpated as a hard mass. However, the elastic nature of cancer tissue is not well understood. The aim of the present study was to evaluate the clinical utility of measuring the elastic modulus (EM) in colorectal cancer tissue. Using a tactile sensor, we measured the EM of 106 surgically resected colorectal cancer tissues. Data on(More)
A new histological classification of neuroendocrine tumors (NETs) was established in WHO 2010. ENET and NCCN proposed treatment algorithms for colorectal NET. Retrospective study of NET of the large intestine (colorectal and appendiceal NET) was performed among institutions allied with the Japanese Society for Cancer of the Colon and Rectum, and 760(More)
Skeletal muscle is the major site for glucose disposal, the impairment of which closely associates with the glucose intolerance in diabetic patients. Diabetes-related ankyrin repeat protein (DARP/Ankrd23) is a member of muscle ankyrin repeat proteins, whose expression is enhanced in the skeletal muscle under diabetic conditions; however, its role in energy(More)
This study investigated the transfer of conditioned responses (CR) from wakefulness to sleep in humans, particularly focusing on an inverse relationship between wakefulness and rapid eye movement (REM) sleep. Eight subjects underwent classical differential conditioning during wakefulness using heart rate (HR) as a measure. After the conditioning, an(More)
