Variation In Organ-Specific Pik3ca And Kras Mutant Levels In Normal Human Tissues Correlates With Mutation Prevalence In Corresponding Carcinomas, Barbara L. Parsons, Karen L. Mckim, Meagan B. Myers

United States Food and Drug Administration: Publications

Large-scale sequencing efforts have described the mutational complexity of individual cancers and identified mutations prevalent in different cancers. As a complementary approach, allele specific competitive blocker PCR (ACB-PCR) is being used to quantify levels of hotspot cancer driver mutations (CDMs) with high sensitivity, to elucidate the tissue-specific properties of CDMs, their occurrence as tumor cell subpopulations, and their occurrence in normal tissues. Here we report measurements of PIK3CA H1047R mutant fraction (MF) in normal colonic mucosa, normal lung, colonic adenomas, colonic adenocarcinomas, and lung adenocarcinomas. We report PIK3CA E545K MF measurements in those tissues, as well as in normal breast, …

Cyclosporine Exacerbates Ketamine Toxicity In Zebrafish: Mechanistic Studies On Drug–Drug Interaction, Bonnie L. Robinson, Melanie Dumas, Syed F. Ali, Merle G. Paule, Qiang Gu, Jyotshna Kanungo

United States Food and Drug Administration: Publications

Cyclosporine A (CsA) is an immunosuppressive drug commonly used in organ transplant patients to prevent allograft rejections. Ketamine is a pediatric anesthetic that noncompetitively inhibits the calcium-permeable N-methyl-D-aspartic acid receptors. Adverse drug–drug interaction effects between ketamine and CsA have been reported in mammals and humans. However, the mechanism of such drug–drug interaction is unclear. We have previously reported adverse effects of combination drugs, such as verapamil/ketamine and shown the mechanism through intervention by other drugs in zebrafish embryos. Here, we show that ketamine and CsA in combination produce developmental toxicity even leading to lethality in zebrafish larvae when exposure began …

Detection Of Allergen Markers In Food: Analytical Methods, Girdhari M. Sharma, Sefat E. Khuda, Christine H. Parker, Anne C. Eischeid, Marion Pereira

United States Food and Drug Administration: Publications

Food allergens are proteins that are well tolerated by most, but can cause severe reactions in sensitive individuals. Since there is no cure for food allergy, strict adherence to an allergen-free diet is the only safe choice currently available for allergic consumers. Accurate food labeling can help consumers avoid foods containing an allergenic ingredient. Regulatory agencies have mandated the labeling of major food allergens on packaged foods to help with safe food choices. However, the inadvertent presence of an allergen in food due to cross-contact and labeling error can jeopardize consumer health. Analytical methods are developed for allergen detection and …

Multiple Imputation To Evaluate The Impact Of An Assay Change In National Surveys, Maya Sternberg

United States Food and Drug Administration: Publications

National health surveys, such as the National Health and Nutrition Examination Survey, are used to monitor trends of nutritional biomarkers. These surveys try to maintain the same biomarker assay over time, but there are a variety of reasons why the assay may change. In these cases, it is important to evaluate the potential impact of a change so that any observed fluctuations in concentrations over time are not confounded by changes in the assay. To this end, a subset of stored specimens previously analyzed with the old assay is retested using the new assay. These paired data are used to …

Food Safety Traceability, Yimin Wei, Boli Guo, Hongyan Liu, Shuai Wei, Jianrong Zhang

United States Food and Drug Administration: Publications

With globalized economics, it is becoming more frequent to trade food across country and regional borders, which leads to expanding and spreading of all kinds of food safety incidents and hazards. Mad cow disease, foot and mouth disease, avian flu and other zoonotic diseases pose a grave threat to food safety and human health, causing serious economic losses for food industries and causing social panic at the same time. In order to reduce the losses caused by such serious zoonotic diseases, as well as to ensure food safety, many countries have started to implement food safety traceability systems. The European …

Quality By Design: Process Trajectory Development For A Dynamic Pharmaceutical Coprecipitation Process Based On An Integrated Real‐Time Process Monitoring Strategy, Huiquan Wu, Mansoor A. Khan

United States Food and Drug Administration: Publications

Increasing prevalence of poorly water‐soluble drugs in pharmaceutical development provides notable risks of new products demonstrating low and erratic bioavailability. This dissolution‐limited bioavailability may have consequences for safety and efficacy, particularly for drugs delivered by the oral route of administration. Several novel drug delivery technologies have been developed to improve drug solubility, dissolution rates, and bioavailability. Among those are solid dispersion, nanotechnology, supercritical fluid technology, lipid‐based technology, and crystal engineering. Although these strategies are available for enhancing the bioavailability of drugs with low aqueous solubility, the success of these approaches is not yet guaranteed and is greatly dependent on the …

Disparities In Hypertension And Cardiovascular Disease In Blacks: The Critical Role Of Medication Adherence, Keith C. Ferdinand, Kapil Yadav, Samar A. Nasser, Helene D. Clayton-Jeter, John Lewin, Dennis R. Cryer, Fortunato Fred Senatore

United States Food and Drug Administration: Publications

Blacks are two to three times as likely as whites to die of preventable heart disease and stroke. Declines in mortality from heart disease have not eliminated racial disparities. Control and effective treatment of hypertension, a leading cause of cardiovascular disease, among blacks is less than in whites and remains a challenge. One of the driving forces behind this racial/ethnic disparity is medication nonadherence whose cause is embedded in social determinants. Eight practical approaches to addressing medication adherence with the potential to attenuate disparities were identified and include: (1) patient engagement strategies, (2) consumer-directed health care, (3) patient portals, (4) …

United States Food and Drug Administration: Publications

Purpose: Apolipoprotein A-I (ApoA-I) and apolipoprotein B-100 (ApoB-100) are amphipathic proteins that are strong predictors of cardiovascular disease risk. The traceable calibration of apolipoprotein assays is a persistent challenge, especially for ApoB-100, which cannot be solubilized in purified form.

Experimental design: A simultaneous quantitation method for ApoA-I and ApoB-100 was developed using tryptic digestion without predigestion reduction and alkylation, followed by LC separation coupled with isotope dilution MS analysis. The accuracy of the method was assured by selecting structurally exposed signature peptides, optimal choice of detergent, protein: enzyme ratio, and incubation time. Peptide calibrators were value assigned by isobaric tagging …
