Detection of Rickettsia spp in Ticks by MALDI-TOF MS

PLOS Neglected Tropical Diseases, 2015
Matrix Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) has been shown to be an effective tool for the rapid identification of arthropods, including tick vectors of human diseases.The objective of the present study was to evaluate the use of MALDI-TOF MS to identify tick species, and to determine the presence of ...

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, EarlyView.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Tissue‐Specific and Spatially Dependent Metabolic Signatures Perturbed by Injury in Male and Female Mice

Arthritis &Rheumatology, EarlyView.
Objective Osteoarthritis, the leading cause of disability worldwide, disproportionately affects women, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.

End-group functionalization of poly(2-oxazoline)s using methyl bromoacetate as initiator followed by direct amidation [PDF]

, 2019
Poly(2-alkyl/aryl-2-oxazoline)s (PAOx) are an alluring class of polymers for many applications due to the broad chemical diversity that is accessible for these polymers by simply changing the initiator, terminating agent and the monomer(s) used in their ...
