Priming Deficiency In Male Subjects At Risk For Alcoholism: The N4 During A Lexical Decision Task, Lance O. Bauer

UCHC Articles - Research

Abstract

Background

While there is extensive literature on the relationship between the P3 component of event-related potentials (ERPs) and risk for alcoholism, there are few published studies regarding other potentially important ERP components. One important candidate is the N4(00) component in the context of semantic processing, as abnormalities in this component have been reported for adult alcoholics.

Method

A semantic priming task was administered to non-alcohol dependent male offspring (18 to 25 years) of alcoholic fathers [high risk (HR) n=23] and non-alcoholic fathers [low risk (LR) n=28], to study whether the two groups differ in terms of the N4 component. …

A Rapid Non-Destructive Method For Root Dentin Moisture Measurements, Qiang Zhu, Jin Jiang, Kamran E. Safavi, Larz S.W. Spångberg

UCHC Articles - Research

Dentin moisture content is important in adhesive bonding and structural strength research. However, there is no rapid method available to assess dentin moisture without sample destruction. This study examined the use of a digital grain moisture meter to measure root dentin moisture in vitro. Extracted mandibular single rooted teeth were sectioned at the CEJ. The moisture of the root dentin was measured at six measuring modes for different grains and repeated five times. Dentin weight changes before and after drying were measured to obtain control values. The control values were compared with machine readings. In conclusion, (1) Each non-destructive measurement …
