Fabrication of post-functionalizable, bio-repellent, electroactive polyurethane interface on gold surface by Surface-Assisted (SurfAst) polymerization.

Langmuir 2020 May 27. Epub 2020 May 27.

This study describes surface-assisted (SurfAst) urethane polymerization providing modular/post-functionalizable, bio-repellent, electroactive ~10 to 100 nm thick polyurethane (PU) interface on the gold surface. SurfAst is a functionalization methodology based on sequential incubation steps of alkane-diisocyanates and alkanediol monomers. The gold surface is functionalized by alkane-diisocyanates in the first incubation step and our theoretical calculations reveal that while the isocyanate group atoms (N, C, O) at the one end of molecule exhibits strong interactions (~900 meV) with surface atoms, the other end group remains unreacted.

Association of Salivary Cholinesterase With Arthropod Vectors of Disease.

J Med Entomol 2020 May 27. Epub 2020 May 27.

Knipling-Bushland U.S. Livestock Insects Research Laboratory, USDA-ARS, Kerrville, TX.

Acetylcholinesterase (AChE) was previously reported to be present in saliva of the southern cattle tick, Rhipicephalus (Boophilus) microplus (Canestrini), with proposed potential functions to 1) reduce acetylcholine toxicity during rapid engorgement, 2) modulate host immune responses, and 3) to influence pathogen transmission and establishment in the host. Potential modulation of host immune responses might include participation in salivary-assisted transmission and establishment of pathogens in the host as has been reported for a number of arthropod vector-borne diseases. If the hypothesis that tick salivary AChE may alter host immune responses is correct, we reasoned that similar cholinesterase activities might be present in saliva of additional arthropod vectors.

Hybrid magnetic nanovectors promote selective glioblastoma cell death through a combined effect of lysosomal membrane permeabilization and chemotherapy.

ACS Appl Mater Interfaces 2020 May 27. Epub 2020 May 27.

Glioblastoma multiforme is the most aggressive brain tumor due to its high invasiveness and genetic heterogeneity. Moreover, the blood-brain barrier prevents many drugs from reaching a therapeutic concentration at the tumor site, and most of the chemotherapeutics lacks in specificity towards cancer cells, accumulating in both healthy and diseased tissues, with severe side effects. Here, we present in vitro investigations on lipid-based nanovectors encapsulating a drug, nutlin-3a, and superparamagnetic iron oxide nanoparticles, to combine the pro-apoptotic action of the drug and the hyperthermia mediated by superparamagnetic iron oxide nanoparticles stimulated with an alternating magnetic field.

Grupo de Investigación en Polímeros, Universidad Industrial de Santander, 681011, Colombia. and Centro de Investigaciones en Catálisis (@CICATUIS), Universidad Industrial de Santander, 681011, Colombia.

Ordered materials with interconnected porosity allow the diffusion of molecules within their inner porous structure to access the active sites located in the microporous core. As a follow-up of our work on engineering of MOF-808, in this contribution, we study the synthesis of defective MOF-808 using two different strategies: the use of modulators and the surfactant-assisted synthesis to obtain materials with ordered and interconnected pores. The results of the study indicated that (i) the use of modulators of different chain length led to the formation of microporous/mesoporous MOFs through the formation of missing linker defects.

Elastic Lightweight Robotics Group, Department of Electrical Engineering and Information Technology, Robotics Research Institute, Technische Universität Dortmund, Dortmund, Germany.

In the advent of intelligent robotic tools for physically assisting humans, user experience, and intuitiveness in particular have become important features for control designs. However, existing works predominantly focus on performance-related measures for evaluating control systems as the subjective experience of a user by large cannot be directly observed. In this study, we therefore focus on agency-related interactions between control and embodiment in the context of physical human-machine interaction. Read More
