Comparing Communication Technology On Chinese, English, And Spanish Diabetes Web Sites, Yanko F Michea, Karen Pancheri, Yang Gong, Elmer Bernstam Jan 2002

Comparing Communication Technology On Chinese, English, And Spanish Diabetes Web Sites, Yanko F Michea, Karen Pancheri, Yang Gong, Elmer Bernstam

Faculty, Staff and Student Publications

Technological and cultural factors influence access to health information on the web in multifarious ways. We evaluated structural differences and availability of communication services on the web in three diverse language and cultural groups: Chinese, English, and Spanish. A total of 382 web sites were analyzed: 144 were English language sites (38%), 129 were Chinese language sites (34%), and 108 were Spanish language sites (28%). We did not find technical differences in the number of outgoing links per domain or the total availability of communication services between the three groups. There were differences in the distribution of available services between …

Cognitive Differences In Chart Reading: A Comparison Of Nurses And Physicians, Todd R. Johnson, Vimla L. Patel, James P. Turley

Faculty, Staff and Student Publications

This pilot study compares the mental models of a patient constructed by nurses and physicians while reading an electronic medical record. Preliminary results suggest that the participants' summaries were both quantitatively and qualitatively different. The physician made more inferences and focused on deeper relationships in the record, whereas the nurse focused on the descriptive surface structure of the record.


Preliminary Evaluation Of A Guideline Classification System, Elmer Bernstam, Nachman Ash, Mor Peleg, Samson Tu, Edward H. Shortliffe, Robert A. Greenes Jan 2001

Preliminary Evaluation Of A Guideline Classification System, Elmer Bernstam, Nachman Ash, Mor Peleg, Samson Tu, Edward H. Shortliffe, Robert A. Greenes

Faculty, Staff and Student Publications

In a previous paper, we presented a proposed expansion of the National Guideline Clearing-house (NGC) classification1. We performed a preliminary evaluation of the classification based on 100 guidelines randomly selected from the NGC collection. We found that 89 of the 100 guidelines could be assigned to a single guideline category. To test inter-observer agreement, twenty guidelines were also categorized by a second investigator. Agreement was found to be 40-90% depending on the axis, which compares favorably with agreement among MeSH indexers (30-60%)2. We conclude that categorization is feasible. Further research is needed to clarify axes with poor inter-observer agreement.

Phosphorylation Of Elongation Factor 1 And Ribosomal Protein S6 By Multipotential S6 Kinase And Insulin Stimulation Of Translational Elongation, Y W Chang, J A Traugh Nov 1997

Phosphorylation Of Elongation Factor 1 And Ribosomal Protein S6 By Multipotential S6 Kinase And Insulin Stimulation Of Translational Elongation, Y W Chang, J A Traugh

Faculty, Staff and Student Publications

Stimulation of protein synthesis in response to insulin is concomitant with increased phosphorylation of initiation factors 4B and 4G and ribosomal protein S6 (Morley, S. J., and Traugh, J. A. (1993) Biochimie 75, 985-989) and is due at least in part to multipotential S6 kinase. When elongation factor 1 (EF-1) from rabbit reticulocytes was examined as substrate for multipotential S6 kinase, up to 1 mol/mol of phosphate was incorporated into the alpha, beta, and delta subunits. Phosphorylation of EF-1 resulted in a 2-2. 6-fold stimulation of EF-1 activity, as measured by poly(U)-directed polyphenylalanine synthesis. The rate of elongation was also …


Estimation Of The Incidence Of A Rare Genetic Disease Through A Two-Tier Mutation Survey, R Chakraborty, M R Srinivasan, S Raskin Jun 1993

Estimation Of The Incidence Of A Rare Genetic Disease Through A Two-Tier Mutation Survey, R Chakraborty, M R Srinivasan, S Raskin

Faculty, Staff and Student Publications

Recent attempts to detect mutations involving single base changes or small deletions that are specific to genetic diseases provide an opportunity to develop a two-tier mutation-screening program through which incidence of rare genetic disorders and gene carriers may be precisely estimated. A two-tier survey consists of mutation screening in a sample of patients with specific genetic disorders and in a second sample of newborns from the same population in which mutation frequency is evaluated. We provide the statistical basis for evaluating the incidence of affected and gene carriers in such two-tier mutation-screening surveys, from which the precision of the estimates …


Can An Anesthesia Machine Flush Valve Provide For Effective Jet Ventilation?, S D Gaughan, J L Benumof, G T Ozaki Apr 1993

Can An Anesthesia Machine Flush Valve Provide For Effective Jet Ventilation?, S D Gaughan, J L Benumof, G T Ozaki

Faculty, Staff and Student Publications

Transtracheal jet ventilation (TTJV) using a percutaneously inserted intravenous (IV) catheter for the patient who cannot be ventilated or tracheally intubated or, using a jet stylet for changing endotracheal tubes (ETT) in patients for whom subsequent ventilation and/or tracheal reintubation may be difficult, are extremely valuable therapeutic options. The jet ventilation system must have a sufficiently high pressure-oxygen source to drive oxygen through noncompliant tubing and through relatively small IV catheters and/or jet stylets in order to achieve adequate ventilation and oxygenation. There is no evidence that using the common gas outlet of an anesthesia machine by activating the flush …

Population Amalgamation And Genetic Variation: Observations On Artificially Agglomerated Tribal Populations Of Central And South America, R Chakraborty, P E Smouse, J V Neel Nov 1988

Population Amalgamation And Genetic Variation: Observations On Artificially Agglomerated Tribal Populations Of Central And South America, R Chakraborty, P E Smouse, J V Neel

Faculty, Staff and Student Publications

The interpretation of data on genetic variation with regard to the relative roles of different evolutionary factors that produce and maintain genetic variation depends critically on our assumptions concerning effective population size and the level of migration between neighboring populations. In humans, recent population growth and movements of specific ethnic groups across wide geographic areas mean that any theory based on assumptions of constant population size and absence of substructure is generally untenable. We examine the effects of population subdivision on the pattern of protein genetic variation in a total sample drawn from an artificial agglomerate of 12 tribal populations …


Genetics And Epidemiology Of Gallbladder Disease In New World Native Peoples, K M Weiss, R E Ferrell, C L Hanis, P N Styne Nov 1984

Genetics And Epidemiology Of Gallbladder Disease In New World Native Peoples, K M Weiss, R E Ferrell, C L Hanis, P N Styne

Faculty, Staff and Student Publications

Native peoples of the New World, including Amerindians and admixed Latin Americans such as Mexican-Americans, are highly susceptible to diseases of the gallbladder. These include cholesterol cholelithiasis (gallstones) and its complications, as well as cancer of the gallbladder. Although there is clearly some necessary dietary or other environmental risk factor involved, the pattern of disease prevalence is geographically associated with the distribution of genes of aboriginal Amerindian origin, and levels of risk generally correspond to the degree of Amerindian admixture. This pattern differs from that generally associated with Westernization, which suggests a gene-environment interaction, and that within an admixed population …


In Vitro Incorporation Of Molybdate Into Demolybdoproteins In Escherichia Coli, Randolph H. Scott, George T. Sperl, John A. Demoss Feb 1979

In Vitro Incorporation Of Molybdate Into Demolybdoproteins In Escherichia Coli, Randolph H. Scott, George T. Sperl, John A. Demoss

Faculty, Staff and Student Publications

When Escherichia coli was grown in the presence of tungstate, inactive forms of two molybdoenzymes, nitrate reductase and formate dehydrogenase, accumulated and were converted to their active forms upon incubation of cell suspensions with molybdate and chloramphenicol. The conversion to the active enzymes did not occur in cell extracts. When incubated with [(99)Mo]molybdate and chloramphenicol, the tungstate-grown cells incorporated (99)Mo into protein components which were released from membranes by procedures used to release nitrate reductase and formate dehydrogenase and which migrated with these activities on polyacrylamide gels. Although neither activity was formed during incubation of the crude extract with molybdate, …

Maximal amounts of prodigiosin were synthesized in either minimal or complete medium after incubation of cultures at 27 C for 7 days. Biosynthesis of prodigiosin began earlier and the range of temperature for formation was greater in complete medium. No prodigiosin was formed in either medium when cultures were incubated at 38 C; however, after a shift to 27 C, pigmentation ensued, provided the period of incubation at 38 C was not longer than 36 hr for minimal medium or 48 hr for complete medium. Washed, nonpigmented cells grown in either medium at 38 C for 72 hr could synthesize …
