Study Finds Flavoring Chemicals in E-Cigarettes Induce Genetic Changes, Impair Functionality of Bronchial Epithelial Cells | Kraft Elder Law

Reuters reported a small test tube experiment examining the effect of e-cigarette flavoring chemicals on bronchial epithelial cells “found that both chemicals induced hundreds of genetic changes in the cells,” and “impaired the ability of the cells to function properly.” The chemicals studied were diacetyl “and its ‘chemical cousin’ 2,3-pentanedione.” Study co-author Joseph Allen, from the Harvard T.H. Chan School of Public Health explained that while “these flavoring chemicals are what we call Generally Regarded As Safe (GRAS)” for the ingestion pathway, “they have not been tested for inhalation safety.” Moreover, he said, “these flavoring chemicals…can cause severe lung disease,” when inhaled. Allen noted that “some of the newer e-cigarette companies like Juul are starting to advertise that their products do not contain (these chemicals).” The study was published in Scientific Reports.

NEW YORK (GenomeWeb) – Genetic factors that contribute to a highly heritable developmental condition called Hirschsprung's disease include a complex suite of risk variants, ranging from common polymorphisms in non-coding elements to rarer coding variants and copy number variants (CNVs), according to new research from investigators at Johns Hopkins University, the University of Washington, the Broad Institute, and New York University. "In our study, we found that the risk of the complex phenotype...

Date: Tuesday, 11 June, 2019 Time: 09:30  – 13:00 Place: Fèlix Serratosa,  Parc Cientific de Barcelona (PCB) This short workshop will describe many aspects of heterologous expression in E.coli, from choice of construct design through to methods to improve the levels of soluble expression and options for co-expression. In addition, it will also address expression in eukaryotic hosts, including secreted proteins and ECDs, and options for co-expression. The workshop will finish with a discussion an...
