Mechanics of dystrophin deficient skeletal muscles in very young mice and effects of age.

Am J Physiol Cell Physiol 2021 May 12. Epub 2021 May 12.

Department of Medicine, Baylor College of Medicine, Houston, Texas, 77030, United Statesgrid.39382.33.

The MDX mouse is an animal model of Duchenne muscular dystrophy, a human disease marked by an absence of the cytoskeletal protein, dystrophin. We hypothesized that (1) dystrophin serves a complex mechanical role in skeletal muscles by contributing to passive compliance, viscoelastic properties, and contractile force production and (2) age is a modulator of passive mechanics of skeletal muscles of the MDX mouse. Using an in vitro biaxial mechanical testing apparatus, we measured passive length-tension relationships in the muscle fiber direction as well as transverse to the fibers, viscoelastic stress-relaxation curves, and isometric contractile properties.

Effects of Side-Chain Spacing and Length on Hydration States of Poly(2-methoxyethyl acrylate) Analogues: A Molecular Dynamics Study.

ACS Biomater Sci Eng 2021 May 12. Epub 2021 May 12.

Institute for Materials Chemistry and Engineering, Kyushu University, Fukuoka 819-0395, Japan.

Hydration states of polymers are known to directly influence the adsorption of biomolecules. Particularly, intermediate water (IW) has been found able to prevent protein adsorption. Experimental studies have examined the IW content and nonthrombogenicity of poly(2-methoxyethyl acrylate) analogues with different side-chain spacings and lengths, which are HP ( is the number of backbone carbons in a monomer) and PMCA ( is the number of carbons in-between ester and ether oxygens of the side-chain) series, respectively.

5' Amplification in Neuroblastoma: A Case Report.

Case Rep Oncol 2021 Jan-Apr;14(1):585-591. Epub 2021 Mar 23.

Institute for Genomic Medicine, Nationwide Children's Hospital, Columbus, Ohio, USA.

Neuroblastoma is the most common cancer in infants younger than 12 months of age, occurring with an incidence of 1 in 100,000 children. The clinical outcome of neuroblastoma ranges from spontaneous regression to treatment-resistant progression and/or metastasis, and accounts for 8-10% of childhood cancer deaths. Segmental chromosomal aberrations, as well as and amplification, are among factors contributing to an unfavorable genomic profile and high-risk disease classification. Read More

Confinement effects and acid strength in zeolites.

Nat Commun 2021 May 11;12(1):2630. Epub 2021 May 11.

Department of Chemistry and Applied Biosciences, ETH Zurich, c/o USI Campus, Via Giuseppe Buffi 13, Lugano, Ticino, Switzerland.

Chemical reactivity and sorption in zeolites are coupled to confinement and-to a lesser extent-to the acid strength of Brønsted acid sites (BAS). In presence of water the zeolite Brønsted acid sites eventually convert into hydronium ions. The gradual transition from zeolite Brønsted acid sites to hydronium ions in zeolites of varying pore size is examined by ab initio molecular dynamics combined with enhanced sampling based on Well-Tempered Metadynamics and a recently developed set of collective variables.

Salt-dependent passive adsorption of IgG1κ-type monoclonal antibodies on hydrophobic microparticles.

Biophys Chem 2021 May 6;275:106609. Epub 2021 May 6.

Center for Interdisciplinary Biosciences, Technology and Innovation Park, P.J. Šafárik University, Trieda SNP 1, 040 11 Košice, Slovakia. Electronic address:

Understanding how antibodies adsorb on solid surfaces is essential for developing effective approaches to control this process. In this study, passive adsorptions on the hydrophobic solid surface of a polystyrene microparticle (MP) of two highly similar IgG1 κ-type monoclonal antibodies (mAbs), rituximab, and trastuzumab, were examined in the presence of Hofmeister salts. Except of kosmotropic salts, the screening of electrostatic interactions using salts reduces the passive adsorption of mAbs on MP. Read More

Reduced Intercalation Energy Barrier by Rich Structural Water in Spinel ZnMnO for High-Rate Zinc-Ion Batteries.

ACS Appl Mater Interfaces 2021 May 11. Epub 2021 May 11.

Department of Chemical and Materials Engineering, National Yunlin University of Science and Technology, 123 University Road, Section 3, Douliou, Yunlin 64002, Taiwan.

Aqueous zinc-ion batteries are considered promising next-generation systems for large-scale energy storage due to low cost, environmental friendliness, and high reversibility of the Zn anode. However, the interfacial charge-transfer resistance for the insertion of divalent Zn into cathode materials is normally high, which limits the kinetics of Zn transfer at the cathode/electrolyte interface. This study reveals the presence of rich structural water in spinel ZnMnO (ZnMnO·0. Read More

Vanadium aminophenolates in catechol oxidation: conformity with Finke's common catalyst hypothesis.

Dalton Trans 2021 May;50(18):6088-6099

Group of Inorganic Materials Chemistry, Department of Chemistry, University of Turku, FI-20014 Turku, Finland.

Six known aminophenolate vanadium complexes V1-V6 were examined in 3,5-di-tert-butylcatechol (1, 3,5-DTBC) oxidation. From the complexes V1-V5 have been previously shown to demonstrate catechol oxidase (catecholase) like behavior, catalytically oxidizing 1 to 3,5-di-tert-butyl-1,2-benzoquinone (2, 3,5-DTBQ). A critical re-evaluation of V1-V5, including V6 not assessed earlier, in the aerobic oxidation of 1 has revealed that several catechol dioxygenase products are obtained in addition to 2, which is produced partly by autoxidation.

Lipid signature of neural tissues of marine and terrestrial mammals: consistency across species and habitats.

J Comp Physiol B 2021 May 11. Epub 2021 May 11.

Department of Biology and Marine Biology, University of North Carolina Wilmington, Wilmington, NC, USA.

Marine mammals are exposed to O-limitation and increased N gas concentrations as they dive to exploit habitat and food resources. The lipid-rich tissues (blubber, acoustic, neural) are of particular concern as N is five times more soluble in lipid than in blood or muscle, creating body compartments that can become N saturated, possibly leading to gas emboli upon surfacing. We characterized lipids in the neural tissues of marine mammals to determine whether they have similar lipid profiles compared to terrestrial mammals. Read More

How should external human-machine interfaces behave? Examining the effects of colour, position, message, activation distance, vehicle yielding, and visual distraction among 1,434 participants.

Appl Ergon 2021 May 8;95:103450. Epub 2021 May 8.

Faculty of Mechanical, Maritime and Materials Engineering, Delft University of Technology, Delft, the Netherlands.

External human-machine interfaces (eHMIs) may be useful for communicating the intention of an automated vehicle (AV) to a pedestrian, but it is unclear which eHMI design is most effective. In a crowdsourced experiment, we examined the effects of (1) colour (red, green, cyan), (2) position (roof, bumper, windshield), (3) message (WALK, DON'T WALK, WILL STOP, WON'T STOP, light bar), (4) activation distance (35 or 50 m from the pedestrian), and (5) the presence of visual distraction in the environment, on pedestrians' perceived safety of crossing the road in front of yielding and non-yielding AVs. Participants (N = 1434) had to press a key when they felt safe to cross while watching a random 40 out of 276 videos of an approaching AV with eHMI. Read More

J Inorg Biochem 2021 Apr 29;221:111470. Epub 2021 Apr 29.

School of Chemistry, Monash University, Clayton, Melbourne, VIC 3800, Australia. Electronic address:

Low molecular weight thiols including trypanothione and glutathione play an important function in the cellular growth, maintenance and reduction of oxidative stress in Leishmania species. In particular, parasite specific trypanothione has been established as a prime target for new anti-leishmania drugs. Previous studies into the interaction of the front-line Sb(V) based anti-leishmanial drug meglumine antimoniate with glutathione, have demonstrated that a reduction pathway may be responsible for its effective and selective nature.
