Driving Miss Evers' Boys to the Historical Tuskegee Study of Untreated Syphilis.

The Tuskegee Study of Untreated Syphilis (TSUS) intersects racial and research ethics discourse in medicine and public health. Miss Evers' Boys is a fictionalized play of the 40-year TSUS. In 2016, the Cultural Programs of the National Academy of Sciences and the Shakespeare Theatre Company in Washington, DC co-sponsored a reading of the play at the National Academy of Sciences Auditorium.

Development of a Quantitative LC-MS-MS Assay for Codeine, Morphine, 6-Acetylmorphine, Hydrocodone, Hydromorphone, Oxycodone and Oxymorphone in Neat Oral Fluid.

Recent advances in analytical capabilities allowing for the identification and quantification of drugs and metabolites in small volumes at low concentrations have made oral fluid a viable matrix for drug testing. Oral fluid is an attractive matrix option due to its relative ease of collection, reduced privacy concerns for observed collections and difficulty to adulterate. The work presented here details the development and validation of a liquid chromatography tandem mass spectrometry (LC-MS-MS) method for the quantification of codeine, morphine, 6-acetylmorphine, hydrocodone, hydromorphone, oxycodone and oxymorphone in neat oral fluid.

Assessment of the stability of DNA in specimens collected under conditions for drug testing-A pilot study.

For forensic biological sample collections, the specimen donor is linked solidly to his or her specimen through a chain of custody (CoC) sometimes referenced as a chain of evidence. Rarely, a donor may deny that a urine or oral fluid (OF) specimen is his or her specimen even with a patent CoC. The goal of this pilot study was to determine the potential effects of short-term storage on the quality and quantity of DNA in both types of specimen under conditions that may be encountered with employment-related drug testing specimens.

Detection and quantification of codeine-6-glucuronide, hydromorphone-3-glucuronide, oxymorphone-3-glucuronide, morphine 3-glucuronide and morphine-6-glucuronide in human hair from opioid users by LC-MS-MS.

Current hair testing methods that rely solely on quantification of parent drug compounds are unable to definitively distinguish between drug use and external contamination. One possible solution to this problem is to confirm the presence of unique drug metabolites that cannot be present through contamination, such as phase II glucuronide conjugates. This work demonstrates for the first time that codeine-6-glucuronide, hydromorphone-3-glucuronide, oxymorphone-3-glucuronide, morphine-3-glucuronide and morphine-6-glucuronide are present at sufficient concentrations to be quantifiable in hair of opioid users and that their concentrations generally increase as the concentrations of the corresponding parent compounds increase.

Nanosensor dosimetry of mouse blood proteins after exposure to ionizing radiation.

Giant magnetoresistive (GMR) nanosensors provide a novel approach for measuring protein concentrations in blood for medical diagnosis. Using an in vivo mouse radiation model, we developed protocols for measuring Flt3 ligand (Flt3lg) and serum amyloid A1 (Saa1) in small amounts of blood collected during the first week after X-ray exposures of sham, 0.1, 1, 2, 3, or 6 Gy.

Silicon nano-well arrays for reliable pattern transfer and locally confined high temperature reactions.

Si nano-well arrays, with precisely controlled undercut Si sidewall profiles and flat bottomed pockets, enable uniform nanoscale pattern transfer from resists to metal deposits without degradation of the initial lithographic resolution, as verified by the formation of arrays of Au nano-dots with 10 nm diameter. An additional functionality of the Si nano-wells as local nano-reactors, where the patterned material is enclosed in a Si pocket during high temperature reaction, is demonstrated by thermally inducing a phase transformation of the as-deposited A1 phase of FePt nano-dots to the high coercivity, chemically ordered L1(0) phase.

Misinformation and misbeliefs in the Tuskegee Study of Untreated Syphilis fuel mistrust in the healthcare system.

The Tuskegee Study of Untreated Syphilis (TSUS) is an important issue in research, healthcare, ethics and race relations. The assumed consequences of knowledge of this study on the African-American community include mistrust of the healthcare system. In the July 2005 issue of the Journal of the National Medical Association, Brandon, Isaac and LaVeist (the authors), who were at the Center for Health Disparities Solutions, Johns Hopkins Bloomberg School of Public Health, reported the results of black-white differences in awareness of and knowledge about the TSUS and the effect of that awareness and knowledge on medical mistrust.

Misrepresentations of the Tuskegee Study of Untreated Syphilis.

The Tuskegee Study of Untreated Syphilis (TSUS) is the subject of medical research, healthcare, ethics, race relations and fictitious media portrayals (e.g., movie, play).
