Sialic acid utilization by Cronobacter sakazakii.

Microbial informatics and experimentation

Joseph S, Hariri S, Masood N, Forsythe S.
PMID: 23706082
Microb Inform Exp. 2013 May 24;3(1):3. doi: 10.1186/2042-5783-3-3.

BACKGROUND: The Cronobacter genus is composed of seven species, and can cause infections in all age groups. Of particular concern is C. sakazakii, as this species is strongly associated with severe and often fatal cases of necrotizing enterocolitis and...

Single exosome study reveals subpopulations distributed among cell lines with variability related to membrane content.

Journal of extracellular vesicles

Smith ZJ, Lee C, Rojalin T, Carney RP, Hazari S, Knudson A, Lam K, Saari H, Ibañez EL, Viitala T, Laaksonen T, Yliperttula M, Wachsmann-Hogiu S.
PMID: 26649679
J Extracell Vesicles. 2015 Dec 07;4:28533. doi: 10.3402/jev.v4.28533. eCollection 2015.

Current analysis of exosomes focuses primarily on bulk analysis, where exosome-to-exosome variability cannot be assessed. In this study, we used Raman spectroscopy to study the chemical composition of single exosomes. We measured spectra of individual exosomes from 8 cell...

High-throughput monitoring of human tumor-specific T-cell responses with large peptide pools.

Oncoimmunology

Chevalier MF, Bobisse S, Costa-Nunes C, Cesson V, Jichlinski P, Speiser DE, Harari A, Coukos G, Romero P, Nardelli-Haefliger D, Jandus C, Derré L.
PMID: 26451296

In immune intervention trials, the comprehensive investigation of immunogenicity or T-cell epitope-mapping is challenging especially when a large set of epitopes needs to be screened and limited sample material is available. To this end, T-cell responses are often monitored...

Non-diffracting multi-electron vortex beams balancing their electron-electron interactions.

Nature communications

Mutzafi M, Kaminer I, Harari G, Segev M.
PMID: 28935885
Nat Commun. 2017 Sep 21;8(1):650. doi: 10.1038/s41467-017-00651-z.

The wave-like nature of electrons has been known for almost a century, but only in recent years has the ability to shape the wavefunction of EBeams (Electron-Beams) become experimentally accessible. Various EBeam wavefunctions have been demonstrated, such as vortex,...

Pd-Catalyzed and Copper Assisted Regioselective Sequential C2 and C7 Arylation of Thiazolo[5,4-f]quinazolin-9(8H)-one with Aryl Halides.

Organic letters

A selective functionalization of thiazolo[5,4-f]quinazolin-9(8H)-one has been developed through sequential activation of C-H bonds to furnish diarylated compounds. This strategy allows the regioselective C2 and C7 arylation by a judicious choice of coupling partners and bases, requiring no additional...
