Multiplexed Surface Protein Detection and Cancer Classification Using Gap-Enhanced Magnetic-Plasmonic Core-Shell Raman Nanotags and Machine Learning Algorithm.

Cancer is the second leading cause of death attributed to disease worldwide. Current standard detection methods often rely on a single cancer marker, which can lead to inaccurate results, including false negatives, and an inability to detect multiple cancers simultaneously. Here, we developed a multiplex method that can effectively detect and classify surface proteins associated with three distinct types of breast cancer by utilizing gap-enhanced Raman scattering nanotags and machine learning algorithm.

Alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 1 can support immune responses toward tumors overexpressing ganglioside D3 in mice.

An immunotherapeutic strategy is discussed supporting anti-tumor activity toward malignancies overexpressing ganglioside D3. GD3 can be targeted by NKT cells when derived moieties are presented in the context of CD1d. NKT cells can support anti-tumor responses by secreting inflammatory cytokines and through cytotoxicity toward CD1dGD3 tumors.

Measuring hot flashes: summary of a National Institutes of Health workshop.

The etiology and mechanism of hot flashes remain incompletely understood. Future studies of hormonal and neurologic systems may provide promising leads to improve our understanding of the basic phenomenon and perhaps also shed light on the placebo effect. However, this is likely a complex undertaking.

In situ diffusion experiment in granite: phase I.

A program of in situ experiments, supported by laboratory studies, was initiated to study diffusion in sparsely fractured rock (SFR), with a goal of developing an understanding of diffusion processes within intact crystalline rock. Phase I of the in situ diffusion experiment was started in 1996, with the purpose of developing a methodology for estimating diffusion parameter values. Four in situ diffusion experiments, using a conservative iodide tracer, were performed in highly stressed SFR at a depth of 450 m in the Underground Research Laboratory (URL).

NAAT-identified and self-reported gonorrhea and chlamydial infections: different at-risk population subgroups?

Background: Information on the characteristics and behaviors of persons at high risk for gonorrhea and chlamydial infection has typically been derived from studies of sexually transmitted disease (STD) clinic populations. The Baltimore STD and Behavior Survey (BSBS) used urine-based nucleic acid amplification testing (NAAT) to assess the prevalence and behavioral correlates of gonorrhea and chlamydial infection in a population-based cross-sectional survey of adults in Baltimore, Maryland.

Goal: The goal of this study was to examine the demographic characteristics and behavioral markers of gonorrhea and chlamydial infection as reported by adults with a self-reported history of gonorrhea and chlamydial infection and to compare these to the characteristics and behaviors of individuals with current NAAT-identified gonorrhea and/or chlamydial infection.

Untreated gonococcal and chlamydial infection in a probability sample of adults.

Context: The prevalence and distribution of gonococcal and chlamydial infections in the general population are poorly understood. Development of nucleic acid amplification tests, such as the ligase chain reaction assay, provides new opportunities to estimate the prevalence of untreated infections in the population.

Objective: To estimate the overall prevalence of untreated gonococcal and chlamydial infections and to describe patterns of infection within specific demographic subgroups of the young adult population in Baltimore, Md.

The impact of T-ACASI interviewing on reported drug use among men who have sex with men.

Measurements of drug use and other illicit or stigmatized behaviors are subject to nontrivial underreporting biases. During in-person surveys, respondents are more likely to report such behaviors when interviewed using techniques that maximize interviewee privacy, e.g.

Correlates of sexually transmitted bacterial infections among U.S. women in 1995.

Context: Sexually transmitted diseases (STDs) of bacterial origin such as gonorrhea and chlamydial infection can lead to pelvic inflammatory disease (PID) and infertility. Identifying behaviors and characteristics associated with infection may assist in preventing these often asymptomatic diseases and their sequelae.

Methods: Data from 9,882 sexually active women who participated in the 1995 National Survey of Family Growth describe the characteristics of women who report a history of infection with a bacterial STD or of treatment for PID.

Monitoring the health status and impact of treatment on Americans: the Medicare Beneficiary Health Status Registry.

Objective: A major new survey program, the Medicare Beneficiary Health Status Registry (MBHSR), has been proposed to improve the monitoring of the health status of Medicare beneficiaries. The MBHSR would collect data by mail with telephone follow up of nonrespondents to permit economical assessment of a total Registry of approximately 200,000 Medicare beneficiaries, approximately 54,000 of whom would be surveyed in any given year. (Surveys would be conducted of samples of new enrollees who would be reinterviewed every five years.

Interview Mode and Measurement of Sexual Behaviors: Methodological Issues.

Studies of sexual and other sensitive behaviors are often fraught with a variety of reporting biases. When IAQs are used to collect data, respondents may underreport certain sensitive behaviors and overreport normative behaviors. SAQs can also pose problems: requiring that respondents be literate and able to follow skip patterns.

Measuring AIDS-Related Behaviors in Older Populations: Methodological Issues.

Because of a dearth of research on reporting biases in the measurement of HIV-related sexual and drug use behaviors in older populations, it is frequently assumed that methodological findings of research conducted with younger populations will generalize to older respondents. In this study, estimates of the effect of the experimental manipulation of interview mode (interviewer administered vs. self-administered) were derived separately for three age strata: 12 to 49, 50 to 64, and 65+.

Effects of interview mode on bias in survey measurements of drug use: do respondent characteristics make a difference?

Three recent empirical studies have provided strong evidence that self-administered questionnaires (SAQs), compared with interviewer questioning, substantially improve the reporting of drug use in population surveys. Specifically, SAQs appear to diminish underreporting bias. Two of these studies previously reported that this effect of interview mode varied significantly across gender, race/ethnicity, and age.

CD40-tumor necrosis factor receptor-associated factor (TRAF) interactions: regulation of CD40 signaling through multiple TRAF binding sites and TRAF hetero-oligomerization.

CD40 is a TNF receptor superfamily member that provides activation signals in antigen-presenting cells such as B cells, macrophages, and dendritic cells. Multimerization of CD40 by its ligand initiates signaling by recruiting TNF receptor-associated factors (TRAFs) to the CD40 cytoplasmic domain. Recombinant human TRAF proteins overexpressed in insect cells were biochemically characterized and used to finely map TRAF binding regions in the human CD40 cytoplasmic domain.

Monitoring trends in drug use: strategies for the 21st century.

Since the 1970s the United States and other nations have conducted regular statistical monitoring of the prevalence and patterns of drug use in their populations. Given the importance of such surveys for policymaking, their quality is a critical issue, and the biases that may affect their measurements become a major concern. An increasing volume of empirical evidence shows that the mode of administration of a survey can strongly influence the validity of respondents' reports.

Automating Telephone Surveys: Using T-ACASI to Obtain Data on Sensitive Topics.

This paper describes a new interview data collection system that uses a personal computer equipped with a telephone interface card. This system, telephone audio computer-assisted self-interviewing or T-ACASI, offers the economy of telephone interviews while providing the privacy of self-administered questionnaires. We describe T-ACASI design considerations and operational characteristics.

Zenilman's anomaly reconsidered: fallible reports, ceteris paribus, and other hypotheses.

Background And Objectives: In the January-February, 1995 issue of Sexually Transmitted Diseases, Zenilman and colleagues reported a null association between incident sexually transmitted diseases (STDs) and self-reported condom use. That anomalous finding generated a flurry of letters to the editor, some of which were quite heated. This article reconsiders the Zenilman team's results.

Quality of treatment data. Reliability over time of self-reports given by clients in treatment for substance abuse.

This study examines the reliability over a 2-month period of self-reports of drug use, sexual behaviors, and use of treatment services provided by 2,968 clients participating in a large, multisite, prospective study of drug treatment in the United States-the Drug Abuse Treatment Outcome Study (DATOS). Analyses focus on responses to 62 pairs of logically related questions that were asked at two points in time: (1) 1 month after entry into treatment, and (2) 3 months after entry into treatment. Subjects' responses to questions asked at these two time points are assessed for logical consistency.

Assessing consistency of responses to questions on cocaine use.

This study examines consistency of self-reported responses to items within the questionnaire of a multi-site, prospective study of drug abuse treatment in the United States (DATOS). The analyses use data from 2842 interviewer-administered intake interviews. Questions that were logically related are paired and responses compared.

Negative pressure pulmonary edema.

Pulmonary Edema associated with negative airway pressure caused by upper airway obstruction is a most serious complications in anaesthetic practice (Tami et al, 1986). Laryngospasm associated with intubation and general anaesthesia is the most common cause of upper airway obstruction leading to negative pressure pulmonary edema (NPPE) in the anaesthetic adult (Tami et al, 1986). Other risk factors for the development of upper airway obstruction are identified, and individuals at risk should be observed closely while they remain at risk during the post anaesthetic period.
