Molecular architecture of the PBP2–MreC core bacterial cell wall synthesis complex
Nature Communications, 2017 Bacterial wall biosynthesis is a complex process that requires the coordination of multiple enzymes. Here, the authors structurally characterize the PBP2:MreC complex involved in peptidoglycan elongation and cross-linking, and demonstrate that its ...

Cell Wall Biology: Perspectives from Cell Wall Imaging [PDF]
Molecular Plant, 2011 Polysaccharide-rich plant cell walls are important biomaterials that underpin plant growth, are major repositories for photosynthetically accumulated carbon, and, in addition, impact greatly on the human use of plants. Land plant cell walls contain in the region of a dozen major polysaccharide structures that are mostly encompassed by cellulose ...

New Microbes and New Infections, EarlyView., 2014 Abstract We describe a case of fungal keratitis due to Beauveria bassiana in a farmer with Fuchs' dystrophy, treated with amphotericin B. Surgery with penetrating keratoplasty was necessary to resolve the lesions. Susceptibility testing and molecular sequencing permitted the identification and treatment of this rare aetiological agent of invasive ...

Creep Characterization of Inconel 718 Lattice Metamaterials Manufactured by Laser Powder Bed Fusion
Advanced Engineering Materials, EarlyView., 2023 Herein, the creep characteristics of additively manufactured Inconel 718 metamaterials are investigated. The creep behavior of metamaterials and the effects of microstructural defects are assessed, and the microstructure defects are accurately captured using Kachanov's creep damage model.

Characterization of the cell wall and cell wall proteins of Chromatium vinosum [PDF]
Journal of Bacteriology, 1980 Highly purified cell walls of Chromatium vinosum were isolated by differential centrifugation, with or without Triton X-100 extraction. The isolated material had a protein composition similar to that of cell walls obtained by sucrose density gradient centrifugation. Twenty-two proteins were reproducibly detected by sodium dodecyl sulfate-polyacrylamide

Advanced Engineering Materials, EarlyView., 2023 This study aims to explore the feasibility of using a structure inspired by the features of horsetail and human spine as the potential helmet liner, targeting at mitigation of acceleration‐induced injuries. A parametric study is conducted to investigate the effect of individual geometrical variables in the design, indicating its capability to reduce ...

Evaluation of cell wall preparations for proteomics: a new procedure for purifying cell walls from Arabidopsis hypocotyls [PDF]
Plant Methods 2 (2006) 10, 2006 The ultimate goal of proteomic analysis of a cell compartment should be the exhaustive identification of resident proteins; excluding proteins from other cell compartments. Plant cell walls possess specific difficulties. Several reported procedures to isolate cell walls for proteomic analyses led to the isolation of a high proportion (more than 50%) of

Deconstructing the Cell Wall [PDF]
Plant Physiology, 1994 Any microorganism that attempts to colonize a plant must contend with the cell wall. One of the most conspicuous effects of microorganisms on plant cell walls is enzymic degradation. Our interpretation of the significance of this depends on our concept of the plant cell wall, which, however, is paradoxical.

Advanced Engineering Materials, EarlyView., 2023 A numerical scheme is presented to design a lattice support for metallic components additively built via laser powder bed fusion. Results show that thermal‐induced distortion can be respectively reduced by 69%, 58%, and 50% in comparison to a uniform lattice, a fully solid support, and a truss‐based lattice support.
