From 5-HMF to Novel Cyclopentenone-Based Aza Spirocycles: An Intramolecular Aza-Piancatelli Reaction in Action.

With a double objective to upgrade biobased 5-HMF and to access to original spirocycles an intramolecular aza-Piancatelli reaction, a multistep sequence was designed toward appropriate furylcarbinols. The impacts of both the nucleophiles, arylamines compared to alkoxyamines, and the length of the intramolecular tether were studied. After an in-depth evaluation of the different parameters, an extension of the scope provided a library of original azaspiro[4.

Detection of Mycobacterium angelicum in Human Urinary Tract, French Polynesia.

We definitively characterized Mycobacterium angelicum, an aquatic zoonotic opportunistic pathogen of the M. szulgai complex, using a polyphasic approach that included whole-genome sequencing. The sequence was obtained on the island of Tahiti, French Polynesia, from a urine specimen collected from a patient experiencing a urinary tract infection.

Reprogramming reactive glia into interneurons reduces chronic seizure activity in a mouse model of mesial temporal lobe epilepsy.

Reprogramming brain-resident glial cells into clinically relevant induced neurons (iNs) is an emerging strategy toward replacing lost neurons and restoring lost brain functions. A fundamental question is now whether iNs can promote functional recovery in pathological contexts. We addressed this question in the context of therapy-resistant mesial temporal lobe epilepsy (MTLE), which is associated with hippocampal seizures and degeneration of hippocampal GABAergic interneurons.

[Indocyanine green fluorescence to visualize the ureteric vascularization of kidney transplants: An exploratory study].

Introduction: Urinary complications after kidney transplantation are common and can compromise renal function. While they are mainly attributed to ischemic lesions of the ureter, there is no existing method to evaluate its vascularization during surgery. The aim of the study was to evaluate if indocyanine green, revealed by infra-red light andused to visualize tissue perfusion, could provide an appreciation of the ureter's vascularization during kidney transplantation.

5-Hydroxymethylfurfural (HMF) in Organic Synthesis: A Review of its Recent Applications Towards Fine Chemicals.

Background: 5-Hydroxymethylfurfural (5-HMF) is a biomass-derived platform chemical, which can be produced from carbohydrates. In the past decades, 5- HMF has received tremendous attention because of its wide applications in the production of various value-added chemicals, materials and biofuels. The manufacture and the catalytic conversion of 5-HMF to simple industrially-important bulk chemicals have been well reviewed.
