Interest in pharmaceuticals in the environment has increased substantially in recent years. Several studies in particular have assessed human and ecological risks from human pharmaceutical estrogens, such as 17α-ethinyl estradiol (EE2). Regulatory action also has increased, with the USA and other countries developing rules to address estrogens and other(More)
At the Product Quality Research Institute (PQRI) Workshop held last January 14–15, 2014, participants from academia, industry, and governmental agencies involved in the development and regulation of nanomedicines discussed the current state of characterization, formulation development, manufacturing, and nonclinical safety evaluation of(More)
The production of reactive oxygen species on addition of hexavalent chromium (potassium dichromate, K2Cr2O7) to lung cells in culture was studied using flow cytometer analysis. A Coulter Epics Profile II flow cytometer was used to detect the formation of reactive oxygen species after K2Cr2O7 was added to A549 cells grown to confluence. The cells were loaded(More)
The use of nanotechnology in medicine holds great promise for revolutionizing a variety of therapies. The past decade witnessed dramatic advancements in scientific research in nanomedicines, although significant challenges still exist in nanomedicine design, characterization, development, and manufacturing. In March 2013, a two-day symposium “Nanomedicines:(More)
The Nanotechnology Risk Assessment Working Group in the Center for Drug Evaluation and Research (CDER) within the United States Food and Drug Administration was established to assess the possible impact of nanotechnology on drug products. The group is in the process of performing risk assessment and management exercises. The task of the working group is to(More)
The heterocyclic amines (HCAs) found in cooked meat are procar-cinogens that are metabolic alh activated by jV-hydroxylation followed by O-acetylation by the /V-acetyltransferases NATI and NAT2. Despite the importance of metabolic activation in HCA carcinogenicity and the finding that several HCAs are rodent mammary gland carcinogens, nothing was known(More)
This study focuses on the formulation optimization, in vitro and in vivo performance of differently sized nano-crystalline liquid suspensions and spray-dried powders of a poorly soluble BCS class II compound i.e. Danazol. A DoE approach was utilized to optimize stabilizer concentration and formulate danazol (BCS class II) nano-crystalline suspensions and(More)
