Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp3 Hybridization

open access: yesAngewandte Chemie, EarlyView.
A new carbon allotrope with mixed sp–sp3 hybridization has been synthesized through delicately controlled kinetics at a liquid–liquid interface. The resulting material, termed diamondiyne, exhibits an expanded diamond‐type network in the form of small crystallites in a continuous all‐carbon film.

Diagnostic and therapeutic difficulty of chondrosarcoma of the temporomandibular joint: Two cases report

open access: yesOral and Maxillofacial Surgery Cases, 2021
Chondrosarcoma is a malignant tumor characterized by cartilaginous formation. It represents approximately 0.1% of all head and neck neoplasms. Its localization in the temporomandibular joint (TMJ) remains extremely rare.

Mer [PDF]

open access: yesAnthropen, 2018
Comment la mer pourrait-elle constituer un "objet" anthropologique? Quelles différences de traitements et d'analyses a-t-elle stimulée? Et pourquoi est-elle passée en quelques décennies de la périphérie vers le cœur des sciences humaines?

Biotin‐ and Chloroalkane‐Modified Nucleotides for Dual Display of Proteins on DNA Through Streptavidin and Halotag Binding

open access: yesAngewandte Chemie, EarlyView.
Modified 2’‐deoxy‐7‐deazaadenosine bearing a chlorohexyl moiety and 2’‐deoxycytidine nucleotides bearing biotin were used in the enzymatic synthesis of dually modified dsDNAs that served as scaffolds for display of halotag and monomeric streptavidin proteins.

Scalable ω‐Substituted α‐Olefins via Living Chain Transfer Telomerization: A Platform for Next Generation Polyolefins

open access: yesAngewandte Chemie, EarlyView.
A highly versatile and general strategy is presented for the scalable production of practical quantities of ω‐substituted α‐olefins using tris(ω‐substituted alkyl)aluminum telogens that are readily available through a “green” synthesis from commodity triisobutylaluminum and ethene as the taxogen. These new α‐olefins can be designed and used as monomers

Analyzing the MERS disease control strategy through an optimal control problem

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2018
A deterministic mathematical model of the Middle East respiratory syndrome (MERS) disease is introduced. Medical masks, supportive care treatment and a government campaign about the importance of medical masks will be involved in the model as time ...

An Enzymatic Platform for Late‐Stage (Radio)isotope Labelling of Oligonucleotides With Methyltransferases

open access: yesAngewandte Chemie, EarlyView.
State‐of‐the‐art synthesis of radiolabelled oligonucleotides involves multi‐step synthesis with high costs, extended timelines and significant radioactive waste generation. Herein, a dual‐methyltransferase platform enables late‐stage, site‐specific labelling, overcoming these limitations through reduced costs, faster turnaround and minimal radioactive ...

Somatic Evolution of a Germline Antibody Expands its Breadth to Neutralize Early SARS‐CoV‐2 Omicron Variants

open access: yesAdvanced Science, EarlyView.
Engineering of the 148‐germline (148‐GL) antibody reveals a roadmap for overcoming SARS‐CoV‐2 viral escape. By introducing four specific somatic hypermutations, the resulting 148‐M4 variant restores potent neutralization against Omicron BA.1 and BA.4/5.

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

open access: yesAdvanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...
