  • Examining the health effects and bioactive components in Agaricus bisporus mushrooms: a scoping review. [Review]
    J Nutr Biochem. 2020 Jun 13; 84:108453.Blumfield M, Abbott K, … Fayet-Moore F
  • There is evidence from both in vitro and animal models that the consumption of edible mushrooms has beneficial effects on health. It is unclear whether similar effects exist in humans and which bioactive compounds are present. This review synthesises the evidence on the world's most commonly consumed mushroom, Agaricus bisporus to (i) examine its effect on human health outcomes; and (ii) determin…
  • Species-specific quorum sensing represses the chitobiose utilization locus in Vibrio cholerae. [Journal Article]
    Appl Environ Microbiol. 2020 Jul 10 [Online ahead of print]Klancher CA, Newman JD, … Dalia AB
  • The marine facultative pathogen Vibrio cholerae forms complex multicellular communities on the chitinous shells of crustacean zooplankton in its aquatic reservoir. V. cholerae-chitin interactions are critical for the growth, evolution, and waterborne transmission of cholera. This is due, in part, to chitin-induced changes in gene expression in this pathogen. Here, we sought to identify factors th…
  • Chitosan and its Derivatives for Ocular Delivery Formulations: Recent Advances and Developments. [Review]
    Polymers (Basel). 2020 Jul 08; 12(7)Zamboulis A, Nanaki S, … Bikiaris DN
  • Chitosan (CS) is a hemi-synthetic cationic linear polysaccharide produced by the deacetylation of chitin. CS is non-toxic, highly biocompatible, and biodegradable, and it has a low immunogenicity. Additionally, CS has inherent antibacterial properties and a mucoadhesive character and can disrupt epithelial tight junctions, thus acting as a permeability enhancer. As such, CS and its derivatives ar…
  • Tenebrio molitor Larvae Meal Affects the Cecal Microbiota of Growing Pigs. [Journal Article]
    Animals (Basel). 2020 Jul 07; 10(7)Meyer S, Gessner DK, … Eder K
  • The hypothesis tested was that dietary inclusion of insect meal (IM) causes an alteration in the cecal microbiota composition and its fermentation activity of growing pigs. Five-week-old male crossbred pigs were randomly assigned to three groups of 10 pigs each, and fed isonitrogenous diets either without (CON) or with 5% IM (IM5) or 10% IM (IM10) from Tenebrio molitor larvae for four weeks. The …
  • Determination of chitosan content with ratio coefficient method and HPLC. [Journal Article]
    Int J Biol Macromol. 2020 Jul 04 [Online ahead of print]Miao Q, Cui Y, … Guo Z
  • The determination of chitosan is a significant topic that has been growing in importance for a variety of fields. To quantify chitosan, various analytical methods can be used. When high performance liquid chromatographic (HPLC) is used for quantitative analysis of chitosan, the chitosan is mainly hydrolyzed into glucosamine salts, which are determined by HPLC. Average deacetylation degree (DD) ha…
  • Heterologous expression of lytic polysaccharide monooxygenases (LPMOs). A mini-review. [Review]
    Biotechnol Adv. 2020 Jul 04 [Online ahead of print]Gaber Y, Rashad B, … Várnai A
  • Lytic polysaccharide monooxygenases (LPMOs) are relatively new enzymes that have been discovered 10 years ago. LPMOs comprise a diverse group of enzymes which play a pivotal role in the depolymerization of sugar-based biopolymers including cellulose, hemicellulose, chitin, and starch. Their mechanism of action relies on the correct coordination of a copper ion in the active site, which is partly …
  • Extraction, characterization and antimicrobial activity of chitosan from pen shell, Pinna bicolor. [Journal Article]
    Int J Biol Macromol. 2020 Jul 03; 163:423-430.Sudatta BP, Sugumar V, … Nigariga P
  • Chitosan is a biopolymer discovered abundantly on earth specifically in the exoskeleton of shrimps, crabs and insects. In the present study, isolation and characterization of chitosan from the pen shell Pinna bicolor was carried out. In addition to this, the chitosan acquired from the pen shell was tested for its antibacterial activity against five bacterial strains. The FTIR analysis confirmed t…
  • Nature-derived materials for the fabrication of functional biodevices. [Review]
    Mater Today Bio. 2020 Jun; 7:100065.Pradhan S, Brooks AK, Yadavalli VK
  • Nature provides an incredible source of inspiration, structural concepts, and materials toward applications to improve the lives of people around the world, while preserving ecosystems, and addressing environmental sustainability. In particular, materials derived from animal and plant sources can provide low-cost, renewable building blocks for such applications. Nature-derived materials are of in…
  • Deep learning predicts microbial interactions from self-organized spatiotemporal patterns. [Journal Article]
    Comput Struct Biotechnol J. 2020; 18:1259-1269.Lee JY, Sadler NC, … Song HS
  • Microbial communities organize into spatial patterns that are largely governed by interspecies interactions. This phenomenon is an important metric for understanding community functional dynamics, yet the use of spatial patterns for predicting microbial interactions is currently lacking. Here we propose supervised deep learning as a new tool for network inference. An agent-based model was used to…
  • Dynamic Mussel-Inspired Chitin Nanocomposite Hydrogels for Wearable Strain Sensors. [Journal Article]
    Polymers (Basel). 2020 Jun 24; 12(6)Heidarian P, Kouzani AZ, … Yousefi H
  • It is an ongoing challenge to fabricate an electroconductive and tough hydrogel with autonomous self-healing and self-recovery (SELF) for wearable strain sensors. Current electroconductive hydrogels often show a trade-off between static crosslinks for mechanical strength and dynamic crosslinks for SELF properties. In this work, a facile procedure was developed to synthesize a dynamic electrocondu…
  • Chitosan biomaterials application in dentistry. [Review]
    Int J Biol Macromol. 2020 Jun 26 [Online ahead of print]Fakhri E, Eslami H, … Kafil HS
  • Chitosan is a natural biopolymer derived from deacetylation of chitin and it has been investigated with interdisciplinary approaches for multitude applications. Chitosan biomaterials possess unique properties such as biocompatibility, biodegradability, non-toxicity, muco-adhesion and a wide range of antibacterial and antifungal activity. Additionally, chitosan is the only cationic polysaccharide …
