In Vitro Methods for Assessing Nanoparticle Toxicity.

Methods Mol Biol 2019 ;1894:1-29

Department of Chemical and Materials Engineering, University of Kentucky, Lexington, KY, USA.

As a consequence of their increase in annual production and widespread distribution in the environment, nanoparticles potentially pose a significant public health risk. The sought-after catalytic activity granted by their physiochemical properties doubles as a hazard to physiological processes following exposure through inhalation, oral, transdermal, subcutaneous, and intravenous uptake. Upon uptake into the body, their size, morphology, surface charge, coating, and chemical composition augment the response of biological systems to the materials and enhance their toxicity. Read More

The Structural Effects of Modality on the Rise of Symbolic Language: A Rebuttal of Evolutionary Accounts and a Laboratory Demonstration.

Front Psychol 2018 28;9:2300. Epub 2018 Nov 28.

Laboratoire de Sciences Phonétiques, Département de Linguistique, Université de Montréal, Montreal, QC, Canada.

Why does symbolic communication in humans develop primarily in an oral medium, and how do theories of language origin explain this? Non-human primates, despite their ability to learn and use symbolic signs, do not develop symbols as in oral language. This partly owes to the lack of a direct cortico-motoneuron control of vocalizations in these species compared to humans. Yet such modality-related factors that can impinge on the rise of symbolic language are interpreted differently in two types of evolutionary storylines. Read More

Electrophilic nitro-fatty acids (NO2-FA) showed beneficial signaling actions in preclinical studies, and safety in Phase 1 clinical trials. Detailed understanding of the pharmacokinetics (PK) of NO2-FA is complicated by the capability of electrophilic fatty acids to alkylate thiols reversibly, become esterified in various complex lipids, and the instability of the nitroalkene moiety during enzymatic and base hydrolysis. Herein, we report the mechanism and kinetics of absorption, metabolism, and distribution of the endogenously-detectable and prototypical NO2-FA 10-nitro-oleic acid (10-NO2-OA) in dogs after oral administration.

Effect of gap junction-mediated intercellular communication on TGF-β induced epithelial-to-mesenchymal transition.

Biochem Biophys Res Commun 2018 Dec 10. Epub 2018 Dec 10.

Department of Cellular Physiological Chemistry, Tokyo Medical and Dental University, 1-5-45, Yushima, Bunkyo-ku, Tokyo, 113-8510, Japan. Electronic address:

Epithelial-to-mesenchymal transition (EMT) is the process in which epithelial cells lose cell polarity and cell adhesion with surrounding cells to obtain migratory and invasive abilities. On the other hand, the expression of connexin is decreased or lacked in the many types of tumor cells. This study examined the effect of gap junctional intercellular communication (GJIC) on EMT induced by the transforming growth factor-β1 (TGF-β1). Read More
