    Trends Biotechnol 2018 Apr 16. Epub 2018 Apr 16.
    Key Laboratory of Industrial Biotechnology, Ministry of Education, School of Biotechnology, Jiangnan University, Wuxi, 214122, China.
    Glycosaminoglycans (GAGs) and their oligosaccharides have attracted extensive attention because of their wide applications in cosmetics, health, and clinical treatment of, for example, thrombus, osteoarthritis, rheumatism, and cancer. Compared to conventional preparation approaches, bio-based strategies for producing GAGs and their oligosaccharides are more promising because they avoid cross-infection of human and animal diseases, use green production processes, and can precisely control the degree of sulfation and molecular weight. This review summarizes recently developed bio-based strategies for producing GAGs, highlighting in particular enzymatic, metabolic engineering, and synthetic biology strategies. Read More

    Band Alignment-Driven Oxidative Injury to the Skin by Anatase/Rutile Mixed-Phase Titanium Dioxide Nanoparticles under Sunlight Exposure.
    Toxicol Sci 2018 Apr 12. Epub 2018 Apr 12.
    Laboratory of Chemical Biology, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, (P. R. China).
    Anatase/rutile mixed-phase titanium dioxide (TiO2) nanoparticles (NPs) have been found in cosmetics and cotton textiles. Once exposed to sunlight, mixed-phase TiO2 NPs are even more toxic to cells than pure phase NPs, however, the underlying mechanism remains unclear. Considering the unique anatase/rutile heterojunction structure existing in mixed-phase NPs, the potent toxicity of mixed-phase TiO2 NPs probably originates from the high reactive oxygen species (ROS) production because the anatase/rutile heterojunction is constituted by the staggered energy bands that facilitate the electron-hole separation at the interface due to the band alignment.

    Institute of Food Chemistry, University of Hohenheim, D-70599, Stuttgart, Germany.
    For consumer safety reasons, cosmetics that are exposed to light are evaluated with respect to phototoxicity and/or photoallergy (photosensitization). For perfumes/aftershaves, however, these tests are not performed with the cosmetic product but only with single fragrance compounds, which may influence the outcome. In the presence of a sensitizer, photoinduced oxidation of unsaturated fragrances might result in the formation of unwanted products. Read More

    Background: Malignant pleural effusion affects more than 750,000 persons each year across Europe and the United States. Pleurodesis with the administration of talc in hospitalized patients is the most common treatment, but indwelling pleural catheters placed for drainage offer an ambulatory alternative. We examined whether talc administered through an indwelling pleural catheter was more effective at inducing pleurodesis than the use of an indwelling pleural catheter alone. Read More

    Color profiles and stability of acylated and nonacylated anthocyanins as novel pigment sources in a lipstick model: A viable alternative to synthetic colorants.
    J Cosmet Sci 2017 May/Jun;68(3):233-244
    Department of Food Science and Technology, The Ohio State University, Columbus, OH.
    Cosmetics, such as lipstick, can affect an individual's perception of attractiveness and morale. Consumer concern with the safety of synthetic colorants has made the need for alternative natural color sources increasingly urgent. Our goal was to evaluate the feasibility of anthocyanin (ACN) extracts as colorants in lipstick formulations. Read More

    Assessment of bacterial contamination of lipstick using pyrosequencing.
    J Cosmet Sci 2017 Jul/Aug;68(4):245-252
    Department of Oral Microbiology, Research Institute of Oral Science, Gangneung-Wonju National University, Gangneung, 210-702, Korea.
    As soon as they are exposed to the environment, cosmetics become contaminated with microorganisms, and this contamination accumulates with increased use. In this study, we employed pyrosequencing to investigate the diversity of bacteria found on lipstick. Bacterial DNA was extracted from 20 lipstick samples and mixed in equal ratios for pyrosequencing analysis. Read More

    A Comparative In Vivo Scrutiny of Biosynthesized Copper and Zinc Oxide Nanoparticles by Intraperitoneal and Intravenous Administration Routes in Rats.

    Medical Biotechnology and Phage Therapy Laboratory, Department of Post Graduate Studies and Research in Biotechnology, Gulbarga University, Gulbarga, Karnataka, 585 106, India.
    During the present time, anti-microbial features of copper (Cu) and zinc oxide (ZnO) nanoparticles (NPs) are extensively used to combat the growth of pathogenic microbes. CuNPs and ZnONPs are recurrently used in cosmetics, medicine and food additives, and their potential for toxic impacts on human and ecosystem is of high concern. In this study, the fate and toxicity of 16- to 96-nm-ranged biosynthesized copper (Bio-CuNPs) and zinc oxide (Bio-ZnONPs) was assessed in male Wistar rats. Read More

    Extracellular polymer substance synthesized by a halophilic bacterium Chromohalobacter canadensis 28.

    Halophilic microorganisms are producers of a lot of new compounds whose properties suggest promising perspectives for their biotechnological exploration. Moderate halophilic bacterium Chromohalobacter canadensis 28 was isolated from Pomorie salterns as an extracellular polymer substance (EP) producer. The best carbon source for extracellular polymer production was found to be lactose, a sugar received as a by-product from the dairy industry. Read More

    A Review of the Medical Necessity of Comprehensive Patch Testing.

    A novel approach for the synthesis of indolizines from 2-(pyridin-2-yl)acetates, ynals, and alcohols or thiols has been developed. This MCR (multicomponent reaction) that proceeds under the solvent- and metal-free conditions has provided a straightforward path to construct indolizines. Furthermore, this reaction demonstrates other attractive features such as widely available starting materials, mild conditions, good functional group tolerance, and high efficiency. Read More

    We report on high-internal-phase, oil-in-water Pickering emulsions that are stable against coalescence during storage. Viscous, edible oil (sunflower) was emulsified by combining naturally derived cellulose nanocrystals (CNCs) and a food-grade, biobased cationic surfactant obtained from lauric acid and L-arginine (ethyl lauroyl arginate, LAE). The interactions between CNC and LAE were elucidated by isothermal titration calorimetry (ITC) and supplementary techniques. Read More
