Abstract: The present disclosure concerns a broadband hyperspectral imaging spectrophotometer configured to analyze an object and includes an illumination assembly having a source for emitting a light beam and configured so that the light beam scans line by line the object to be analyzed, a focusing mirror, a first mirror folding, and a planar scanning mirror movable in rotation. The illumination assembly, the focusing mirror, the first folding mirror and the planar mirror are arranged to bring the light beam to the object along a line which will be displaced on the object via the scanning mirror. The imaging spectrophotometer further includes two measuring sensors by a distance between the object and the scanning mirror. The focusing mirror is movable in translation to adapt the imager to the measured distance by the measuring sensors.

Abstract: The dimerization of HIV RNA is a key step in the virus replication cycle. Based on RNA DIS crystal structures, a novel kind of compounds, dimeric or not, based on neamine was designed and synthesized. Biological studies showed that such compounds bind and interfere with the targeted RNA sequence, opening a new anti-HIV approach. The crystal structures and bio-chemical experiments showed that the DIS of HIV-1 genomic RNA is a target for new anti-HIV drugs and that those drugs could be derived from aminoglycosides. The results revealed that binding of aminoglycosides to the DIS is specific regarding both the aminoglycoside family and the RNA subtype.
