Working memory and decision-making biases in young adults with a family history of alcoholism: studies from the Oklahoma family health patterns project.

BACKGROUND: Alcohol misuse is more common in persons with a family history of alcoholism (FH+) than in those with no such history (FH-). Among FH+, behavioral disinhibition and male sex seem to signal the presence of an increased risk. METHODS: This study examined cognitive and behavioral characteristics of 175 nonabusing 18- to 30-year-olds, 87 FH+ and 88 FH-, who were further characterized by their degree of behavioral disinhibition using the Sociability scale of the California Personality Inventory. Working memory and decision making were tested using the Stroop Color-Word Test and the Iowa Gambling Task, a simulated card game. RESULTS: Persons with a family history of alcoholism who were behaviorally disinhibited displayed significantly greater interference on the Stroop task than the other subgroups. On the Iowa Gambling Task, FH+ males, but not the females, were significantly more attentive to financial gains than other subgroups, and they had greater consistency in their choice behaviors. CONCLUSIONS: Persons with a family history of alcoholism, in combination with behavioral disinhibition, appears to signal working memory deficits and in combination with male sex indicates an attraction to the rewarding aspects of a risk-taking challenge. These findings are not secondary to heavy exposure to alcohol or other drugs, but instead reflect intrinsic risk-related familial and personal characteristics of the subjects.

Demythologizing sex education in Oklahoma: an attitudinal study.

A randomized study was conducted to determine the distribution of attitudes among Oklahomans of voting age toward sex education and to analyze the relationship of demographic, sociocultural, and attitudinal factors. The state was stratified into six regions. Forty-five percent of the sample lived in urban areas, and 55% in rural areas. Random digit dialing and random selection within households were utilized to ensure a representative sample of the population. Eighty percent of the sample was found to be favorable toward sex education in the public schools, while 20% was unfavorable. A majority of respondents in all religious groups including "fundamentalists" were favorable. Seventeen variables were found to be significant in the univariate analysis of the data; eight were not significant. In a multivariate analysis, three variables, age, Protestant denominational type and female employment, were shown to have predictive ability in determining favorability and unfavorability. Implications for building community support for sex education also are discussed.

Diversity of the microeukaryotic community in sulfide-rich Zodletone Spring (Oklahoma).

The microeukaryotic community in Zodletone Spring, a predominantly anaerobic sulfide and sulfur-rich spring, was examined using an 18S rRNA gene cloning and sequencing approach. The majority of the 288 clones sequenced from three different locations at Zodletone Spring belonged to the Stramenopiles, Alveolata, and Fungi, with members of the phylum Cercozoa, order Diplomonadida, and family Jakobidae representing a minor fraction of the clone library. No sequences suggesting the presence of novel kingdom level diversity were detected in any of the three libraries. A large fraction of stramenopile clones encountered were monophyletic with either members of the genus Cafeteria (order Bicosoecida) or members of the order Labyrinthulida (slime nets), both of which have so far been encountered mainly in marine habitats. The majority of the observed fungal clone sequences belonged to the ascomycetous yeasts (order Saccharomycetales), were closely related to yeast genera within the Hymenobasidiomycetes (phylum Basidiomycetes), or formed a novel fungal lineage with several previously published or database-deposited clones. To determine whether the unexpected abundance of fungal sequences in Zodletone Spring clone libraries represents a general pattern in anaerobic habitats, we generated three clone libraries from three different anaerobic settings (anaerobic sewage digester, pond sediment, and hydrocarbon-exposed aquifer sediments) and partially sequenced 210 of these clones. Phylogenetic analysis indicated that clone sequences belonging to the kingdom Fungi represent a significant fraction of all three clone libraries, an observation confirmed by phospholipid fatty acid and ergosterol analysis. Overall, this work reveals an unexpected abundance of Fungi in anaerobic habitats, describes a novel, yet-uncultured group of Fungi that appears to be widespread in anaerobic habitats, and indicates that several of the previously considered marine protists could also occur in nonmarine habitats.

Metagenomic analysis of the microbial community at Zodletone Spring (Oklahoma): insights into the genome of a member of the novel candidate division OD1.

A metagenomic library was constructed from the anaerobic sediments of a mesophilic sulfur spring. Thirty-five bacterial 16S rRNA gene-containing clones were identified in this library. Analysis of a genomic fragment belonging to candidate division OD1 provided useful insights into the physiology and biochemistry of this novel, yet-uncultured candidate division.

It might work in Oklahoma but will it work in Oakhampton? Context and implementation in the effectiveness literature on domestic smoke detectors.

OBJECTIVE: To explore data on factors affecting implementation processes in papers contributing to a Cochrane systematic review (SR) of smoke alarm interventions, supplemented by further papers not included in the review. DESIGN: Screening for data on implementation on the basis of: (1) primary studies included in a Cochrane SR, (2) further papers relating to these and similar studies, and (3) approaches to authors of these and other relevant studies and reports. RESULTS: Relatively few data were found to help people seeking to implement smoke alarm promotion interventions. CONCLUSIONS: For practitioners and policymakers to be able to build on research evidence, researchers and journal editors need to ensure that sufficient data are published, or are otherwise available to interested parties to move from understanding the evidence to using it.

Allelic variants of ovine prion protein gene (PRNP) in Oklahoma sheep.

1,144 sheep belonging to 21 breeds and known crosses were sequence analyzed for polymorphisms in the ovine PRNP gene. Genotype and allele frequencies of polymorphisms in PRNP known to confer resistance to scrapie, a fatal neurodegenerative disease of sheep, are reported. Known polymorphisms at codons 136 (A/V), 154 (H/R) and 171 (Q/R/H/K) were identified. The frequency of the 171R allele known to confer resistance to type C scrapie was 53.8% and the frequency of the 136A allele known to influence the resistance to type A scrapie was 96.01%. In addition, we report the identification of five new polymorphisms at codons 143 (H/R), 167 (R/S), 180 (H/Y), 195 (T/S) and 196 (T/S). We also report the identification of a novel allele (S/R) at codon 138.
