Engineered microbial biofuel production and recovery under supercritical carbon dioxide.

Nat Commun 2019 Feb 4;10(1):587. Epub 2019 Feb 4.

Department of Civil and Environmental Engineering, Massachusetts Institute of Technology, Cambridge, MA, 02139, USA.

Culture contamination, end-product toxicity, and energy efficient product recovery are long-standing bioprocess challenges. To solve these problems, we propose a high-pressure fermentation strategy, coupled with in situ extraction using the abundant and renewable solvent supercritical carbon dioxide (scCO), which is also known for its broad microbial lethality. Towards this goal, we report the domestication and engineering of a scCO-tolerant strain of Bacillus megaterium, previously isolated from formation waters from the McElmo Dome CO field, to produce branched alcohols that have potential use as biofuels.

A tungsten nitride-based degradable nanoplatform for dual-modal image-guided combinatorial chemo-photothermal therapy of tumors.

Nanoscale 2019 Jan;11(4):2027-2036

Key Laboratory of Biomedical Polymers of Ministry of Education and Department of Chemistry, Wuhan University, Wuhan 430072, P. R. China.

An innovative tungsten-based multifunctional nanoplatform composed of polyethylene glycol (PEG)-modified tungsten nitride nanoparticles (WN NPs) is constructed for tumor treatment. The PEG-WN NPs not only possess strong near-infrared (NIR) absorbance, high photothermal conversion efficiency, and excellent photothermal stability, but also effectively inhibit tumor cells upon 808 nm laser irradiation. After coating with thiolated (2-hydroxypropyl)-β-cyclodextrin (MUA-CD) on the surface, such a nanoplatform can also be used for drug delivery (such as DOX) and presents a synergistic tumor inhibition effect both in vitro and in vivo.

Novel SN38 derivative-based liposome as anticancer prodrug: an in vitro and in vivo study.

Int J Nanomedicine 2019 20;14:75-85. Epub 2018 Dec 20.

Department of Pharmaceutics, School of Pharmacy, Second Military Medical University, Shanghai 200433, People's Republic of China,

Background: Many novel drug delivery systems have been extensively studied to exploit the full therapeutic potential of SN38, which is one of the most potent antitumor analogs of camptothecins (CPTs), whose clinical application is seriously hindered by poor water solubility, low plasmatic stability, and severe toxicity, but results are always unsatisfactory.

Methods: In this study, combining the advantages of prodrug and nanotechnology, a lipophilic prodrug of SN38, SN38-PA, was developed by conjugating palmitic acid to SN38 via ester bond at C position, and then the lipophilic prodrug was encapsulated into a long-circulating liposomal carrier by film dispersion method.

Results: The SN38-PA liposomes were characterized as follows: an average particle size of 80. Read More

Development of Highly Sensitive Immunosensor for Clenbuterol Detection by Using Poly(3,4-ethylenedioxythiophene)/Graphene Oxide Modified Screen-Printed Carbon Electrode.

Sensors (Basel) 2018 Dec 7;18(12). Epub 2018 Dec 7.

Functional Devices Laboratory, Institute of Advanced Technology, Universiti Putra Malaysia, Serdang 43400, Selangor, Malaysia.

Clenbuterol (CLB) is an antibiotic and illegal growth promoter drug that has a long half-life and easily remains as residue and contaminates the animal-based food product that leads to various health problems. In this work, electrochemical immunosensor based on poly(3,4-ethylenedioxythiophene)/graphene oxide (PEDOT/GO) modified screen-printed carbon electrode (SPCE) for CLB detection was developed for antibiotic monitoring in a food product. The modification of SPCE with PEDOT/GO as a sensor platform was performed through electropolymerization, while the electrochemical assay was accomplished while using direct competitive format in which the free CLB and clenbuterol-horseradish peroxidase (CLB-HRP) in the solution will compete to form binding with the polyclonal anti-clenbuterol antibody (Ab) immobilized onto the modified electrode surface.

Overexpression of geraniol synthase induces heat stress susceptibility in Nicotiana tabacum.

Planta 2019 Jan 26;249(1):235-249. Epub 2018 Nov 26.

Department of Biological Science and Technology, Faculty of Industrial Science and Technology, Tokyo University of Science, 6-3-1 Niijuku, Katsushika-ku, Tokyo, 125-8585, Japan.

Main Conclusion: Transgenic tobacco plants overexpressing the monoterpene alcohol geraniol synthase exhibit hypersensitivity to thermal stress, possibly due to suppressed sugar metabolism and transcriptional regulation of genes involved in thermal stress tolerance. Monoterpene alcohols function in plant survival strategies, but they may cause self-toxicity to plants due to their hydrophobic and highly reactive properties. To explore the role of these compounds in plant stress responses, we assessed transgenic tobacco plants overexpressing the monoterpene alcohol geraniol synthase (GES plants). Read More

Multi-dimensional in vitro bioactivity profiling for grouping of glycol ethers.

Regul Toxicol Pharmacol 2019 Feb 22;101:91-102. Epub 2018 Nov 22.

Department of Veterinary Integrative Biosciences, Texas A&M University, College Station, TX, 77843, USA. Electronic address:

High-content screening data derived from physiologically-relevant in vitro models promise to improve confidence in data-integrative groupings for read-across in human health safety assessments. The biological data-based read-across concept is especially applicable to bioactive chemicals with defined mechanisms of toxicity; however, the challenge of data-derived groupings for chemicals that are associated with little or no bioactivity has not been explored. In this study, we apply a suite of organotypic and population-based in vitro models for comprehensive bioactivity profiling of twenty E-Series and P-Series glycol ethers, solvents with a broad variation in toxicity ranging from relatively non-toxic to reproductive and hematopoetic system toxicants.
