The Influence of Repetition and Famousness on the Intracranially Recorded Temporobasal N200.

It is still a matter of debate at which time point faces are recognized as familiar, with some studies claiming a relatively early face recognition and others later effects of familiarity. The authors report on effects of famousness of depicted persons and stimulus repetition on intracranially recorded event-related potentials. Famousness resulted in an increased latency of the N200 component, as well as in an increased amplitude of a later long-lasting potential (N700). In contrast, repetition led to an increased amplitude of the N200 but no increase of its latency. They suppose that the recognition of faces becomes observable within the N200 latency range and that the increased N200 latency reflects a feature processing additional to the holistic face processing.

Quantification and rejection of ocular artifacts in auditory evoked fields in schizophrenics

PURPOSES: To determine what factors affect medical expenditure for the aged insured by the National Health Insurance among secondary medical care areas. METHOD: The original data of municipalities were combined and converted into the data of secondary medical areas. The original data included medical expenditure of the aged in 1994, medical supply factors per 100,000 population (numbers of doctors, numbers of general beds in hospitals, numbers of clinics, etc.) and socio-economic factors (income, proportion of employees for three sectors of industries, population density, average size of family, etc.). Medical expenditures for inpatients and outpatients were used separately as independent variables. The medical supply and socio-economic factors have been used as dependent variables. Multiple regression models were applied to clarify the differences in the contributing factors between inpatient and outpatient. RESULTS: 1. The maximum inpatient and outpatient medical expenditures for the aged are respectively 4 times and 2.6 times more expensive than minimum expenditures among secondary medical care areas. 2. The numbers of beds, income per capita, numbers of doctor, average size of family, proportion of employees for third level industry and income accounted for 57.4% of variance in inpatient medical expenditure of the aged. 3. The proportion of employees for first level industry, the numbers of beds and average members of family accounted for 21.4% of variance in outpatient medical expenditure of the aged. 4. Medical expenditure for inpatients related with medical supply and socioeconomic factors differently from that of outpatients.     

Viability of Bifidobacteria Strains in Yogurt with Added Oat Beta-Glucan and Corn Starch during Cold Storage

Abstract: Probiotics must be consumed at a level of 10⁷ CFU/mL for successful colonization of the gut. In yogurts containing beneficial cultures, the survival of probiotic strains can quickly decline below this critical concentration during cold storage. We hypothesized that beta-glucan would increase the viability of bifidobacteria strains in yogurt during cold storage. Yogurts were produced containing 0.44% beta-glucan (concentrated or freeze-dried) extracted from whole oat flour and/or 1.33% modified corn starch, and bifidobacteria (B. breve or B. longum) at a concentration of at least 10⁹ CFU/mL. All yogurts were stored at 4 °C. Bifidobacteria and yogurt cultures, Streptococcus thermophilus and Lactobacillus delbureckii subsp. bulgaricus, were enumerated from undisturbed aliquots before fermentation, after fermentation, and once a week for 5 wk. S. thermophilus and L. bulgaricus maintained a concentration of at least 10⁸ CFU/mL in yogurts containing concentrated or freeze-dried beta-glucan regardless of starch addition, and in the control with no added beta-glucan or starch. Similarly, the probiotic, Bifidobacterium breve, survived above a therapeutic level in all treatments. The addition of beta-glucan prolonged the survival of Bifidobacterium longum at a concentration of at least 10⁷ CFU/mL by up to 2 wk on average beyond the control. Further, the inclusion of concentrated beta-glucan in yogurt improved survival of B. longum above 10⁷ CFU/mL by 1 wk longer than did freeze-dried beta-glucan. Study results suggest that beta-glucan has a protective effect on bifidobacteria in yogurt when stressed by low-temperature storage. Practical Application: This study suggests that beta-glucan (oat fiber) may improve bifidobacteria survival in yogurt during refrigerated storage.
