Self-renewal of double-negative 3 early thymocytes enables thymus autonomy but compromises the β-selection checkpoint.

Cell Rep 2021 Apr;35(2):108967

Lymphocyte Development and Leukemogenesis Laboratory, Instituto Gulbenkian de Ciência, Calouste Gulbenkian Foundation, Oeiras 2780-156, Portugal. Electronic address:

T lymphocyte differentiation in the steady state is characterized by high cellular turnover whereby thymocytes do not self-renew. However, if deprived of competent progenitors, the thymus can temporarily maintain thymopoiesis autonomously. This bears a heavy cost, because prolongation of thymus autonomy causes leukemia.

-Halamine Polypropylene Nonwoven Fabrics with Rechargeable Antibacterial and Antiviral Functions for Medical Applications.

ACS Biomater Sci Eng 2021 Apr 14. Epub 2021 Apr 14.

Department of Biological and Agricultural Engineering, University of California, One Shields Ave, Davis, California 95616, United States.

Embedding medical and hygiene products with regenerable antimicrobial functions would have significant implications for limiting pathogen contaminations and reducing healthcare-associated infections. Herein, we demonstrate a scalable and industrially feasible methodology to fabricate chlorine rechargeable melt-blown polypropylene (PP) nonwoven fabrics, which have been widely used in hygienic and personal protective products, via a combination of a melt reactive extrusion process and melt-blown technique. Methacrylamide (MAM) was employed as a precursor of halamine monomers and covalently grafted onto the PP backbone to form polypropylene-grafted methacrylamide (PP-g-MAM), which could be chlorinated, yielding biocidal acyclic halamines.

Self-collimating SPECT with multi-layer interspaced mosaic detectors.

IEEE Trans Med Imaging 2021 Apr 14;PP. Epub 2021 Apr 14.

Conventional single photon emission computed tomography (SPECT) relies on mechanical collimation whose resolution and sensitivity are interdependent, the best performance a SPECT system can attain is only a compromise of these two equally desired properties. To simultaneously achieve high resolution and sensitivity, we propose to use sensitive detectors constructed in a multi-layer interspaced mosaic detectors (MATRICES) architecture to accomplish part of the collimation needed.

Solid-Binding Proteins: Bridging Synthesis, Assembly, and Function in Hybrid and Hierarchical Materials Fabrication.

Annu Rev Chem Biomol Eng 2021 Apr 14. Epub 2021 Apr 14.

Department of Chemical Engineering, University of Washington, Seattle, Washington 98115, USA; email:

There is considerable interest in the development of hybrid organic-inorganic materials because of the potential for harvesting the unique capabilities that each system has to offer. Proteins are an especially attractive organic component owing to the high amount of chemical information encoded in their amino acid sequence, their amenability to molecular and computational (re)design, and the many structures and functions they specify. Genetic installation of solid-binding peptides (SBPs) within protein frameworks affords control over the position and orientation of adhesive and morphogenetic segments, and a path toward predictive synthesis and assembly of functional materials and devices, all while harnessing the built-in properties of the host scaffold.

Department of Chemistry, Hong Kong Baptist University, Kowloon Tong, Hong Kong SAR China.

Despite the wide use of magnetic resonance imaging (MRI) as a clinical diagnostic tool, there are still no clinically approved MRI contrast agents that can be applied for cerebral Alzheimer's disease (AD) biomarker imaging. We report here the design and development of the first amyloid-β (Aβ)-targeted, blood-brain barrier (BBB) penetrable theranostic Gd(DOTA)-cyanine dyad, which was synthesized by the conjugation of Gd(DOTA) complex and carbazole-based cyanine dye by the copper(I)-catalyzed azide-alkyne cycloaddition click reaction for imaging of Aβ and in AD mouse models. This dyad, as a multimodal probe, possesses desirable multifunctional properties, including good biocompatibility, low cytotoxicity, high Aβ selectivity, strong fluorescence enhancement upon binding with Aβ species, good paramagnetic properties, high stability, good BBB penetrability, and fast elimination from the mouse.

Self-Organized Implanting of Micro/Nanofiltration Membranes in Advanced Flow μ-Reactors.

ACS Appl Mater Interfaces 2021 Apr 14. Epub 2021 Apr 14.

Centre for Nanotechnology, Indian Institute of Technology Guwahati, Assam 781039, India.

A low-cost, simple, and one-step synthesis of cellulose acetate nanoparticles (CANPs) has been invented using a continuous-flow advanced microfluidic reactor. For this purpose, the CANPs are self-organized inside a cross-junction microchannel by flowing cellulose acetate (CA) dissolved in ,-dimethylformamide (DMF) through the axial inlet and the antisolvent water through the pair of side inlets. The preferential solubility (insolubility) of DMF (CA) to antisolvent water stimulates the in situ synthesis of CANPs at the DMF/water miscible interface following a phase-inversion process.

Macromol Rapid Commun 2021 Apr 14:e2100036. Epub 2021 Apr 14.

School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Key Lab of Electrical Insulation and Thermal Aging, Shanghai Jiao Tong University, No. 800 Dongchuan Rd., Minhang, Shanghai, 200240, China.

Nonaromatic photoluminescent polymers have attracted great attention due to their intriguing photophysical properties and promising implications in optoelectronic and biological areas. The luminescence from these nonconventional luminophores can be well rationalized by the clustering-triggered emission mechanism. Sulfur, although as an n-electron-rich element with big radius, is not been widely utilized in construction of nonconventional luminophores despite of its potential competitiveness in nonaromatic photoluminescent polymers.

Tipless Transseptal Cannula Concept Combines Improved Hemodynamic Properties and Risk-Reduced Placement: an In Silico Proof-of-Concept.

Artif Organs 2021 Apr 13. Epub 2021 Apr 13.

ReCO2very Therapies GmbH, Bad Klosterlausnitz, Germany.

As a leading cause of death worldwide, heart failure is a serious medical condition in which many critically ill patients require temporary mechanical circulatory support (MCS) as a bridge-to-recovery or bridge-to-decision. In many cases, the TandemHeart® system is used to unload the left heart by draining blood from the left atrium (LA) to the femoral artery via a transseptal multistage cannula. However, even though correct positioning of the cannula is crucial for a safe treatment, the long cannula tip currently used in transseptal cannulas complicates positioning, making the cannula moreover vulnerable to displacement during MCS.

Can we treat inflammation by managing misbehaving monocytes?

Simon Milling

Immunology 2021 May;163(1):1-2

Institute of Infection, Immunity and Inflammation, University of Glasgow, Glasgow, UK.

When monocytes migrate from blood into tissues they differentiate into macrophage-like cells. The outcome of this differentiation process is strongly influenced by the tissue environment, and the macrophages produced help control the immunological properties of the tissue. The process of monocyte-macrophage differentiation is therefore potentially attractive when seeking therapeutic targets to amplify or modulate the inflammatory response. Read More
