Langmuir 2021 Apr 12. Epub 2021 Apr 12.

Polymer Science Unit, School of Materials Science, Indian Association for the cultivation of Science, Jadavpur, Kolkata 700032, India.

A poly(vinylidine fluoride) graft random copolymer of -butyl aminoethyl methacrylate (tBAEMA) and oligo(ethylene glycol) methyl ether methacrylate (OEGMA, Mn = 300) [PVDF-g-P(tBAEMA--OEGMA), PVBO] is synthesized by atom transfer radical polymerization (ATRP), and PVBO is fractionated to get a highly water-soluble fraction (PVBO-1) showing a reversible on/off fluorescence behavior with gradual increase and decrease in pH, respectively, achieving a maximum quantum yield of 0.18 at pH = 12. PVBO-1 dissolved in water shows large multimicellar aggregates (MMcA), but at pH 12, crumbling of larger aggregates to much smaller micelles occurs, forming nonconjugated polymer dots (NCPDs), as supported by transmission electron microscopy and dynamic light scattering study.

Int J Phytoremediation 2021 Apr 4:1-12. Epub 2021 Apr 4.

Department of Chemistry, Faculty of Science, Universiti Brunei Darussalam, Gadong, Brunei Darussalam.

In the present study, a synergistic effect between cationic methylene blue (MB) and anionic acid red 1 (AR1) on their concurrent adsorptive removal from aqueous binary solution onto durian rind (DR) was systematically investigated in batch mode across different parameters. The concurrent adsorption was pseudo-second-order kinetics and followed the Langmuir isotherm model, similar to their respective single component. The kinetics and intraparticle diffusion analyses demonstrated that the adsorption rate of MB was a 15-fold faster than AR1, and mass transports were governed by a combination of intraparticle and film diffusion.

J Clin Med 2021 Mar 2;10(5). Epub 2021 Mar 2.

Experimental Rheumatology Unit, Department of Orthopedics, Jena University Hospital, Waldkliniken Eisenberg GmbH, 07607 Eisenberg, Germany.

Background: A major disadvantage of current spacers for two-stage revision total knee arthroplasty (R-TKA) is the risk of (sub-) luxation during mobilization in the prosthesis-free interval, limiting their clinical success with detrimental consequences for the patient. The present study introduces a novel inverse spacer, which prevents major complications, such as spacer (sub-) luxations and/or fractures of spacer or bone.

Methods: The hand-made inverse spacer consisted of convex tibial and concave femoral components of polymethylmethacrylate bone cement and was intra-operatively molded under maximum longitudinal tension in 5° flexion and 5° valgus position. Read More

Review of the existing maximum residue levels for cyproconazole according to Article 12 of Regulation (EC) No 396/2005.

EFSA J 2021 Mar 22;19(3):e06483. Epub 2021 Mar 22.

According to Article 12 of Regulation (EC) No 396/2005, EFSA has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substance cyproconazole. Considering that no application was received to support the renewal of the approval of cyproconazole and considering the expiry date for its approval on 31 May 2021, and that the import tolerances identified were not supported by sufficient data, and are not forming the basis of any existing EU MRLs, but correspond to existing MRLs established by the Codex Alimentarius Commission (codex maximum residue limits; CXLs), the current assessment is limited to CXLs. To assess the occurrence of cyproconazole residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Commission Regulation (EC) No 33/2008, as well as the MRLs established by the Codex Alimentarius Commission.

Charité-Universitätsmedizin Berlin, corporate member of Freie Universität Berlin and Humboldt-Universität zu Berlin, Institute of Virology, Berlin, Germany.

Community protective immunity can affect RNA virus evolution by selecting for new antigenic variants on the scale of years, exemplified by the need of annual evaluation of influenza vaccines. The extent to which this process termed antigenic drift affects coronaviruses remains unknown. Alike the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), seasonal human coronaviruses (HCoV) likely emerged from animal reservoirs as new human pathogens in the past. Read More
