A comparative study of gallstones from children and adults using FTIR spectroscopy and fluorescence microscopy
Oleg Kleiner,Jagannathan Ramesh,Mahmoud Huleihel,Beny Cohen,Keren Kantarovich,Chen Levi,Boris Polyak,Robert S. Marks,Jacov Mordehai,Zahavi Cohen,Shaul Mordechai +10 more
TL;DR: A preliminary study suggests that bilirubin and cholesterol are the main risk factors of gallstone disease.
Novel methodology for the follow-up of acute lymphoblastic leukemia using FTIR microspectroscopy
Jagannathan Ramesh,Joseph Kapelushnik,Jacov Mordehai,Asher Moser,Mahmoud Huleihel,Vitaly Erukhimovitch,Chen Levi,Shaul Mordechai +7 more
TL;DR: The overall effects of drugs administered to the patients can be understood at the molecular level using FTIR-MC and these results are expected to stimulate wider applications of spectroscopy in leukemia research.

An intraline of conical intersections for methylamine
TL;DR: The conical intersections (ci's) related to the N-H bond in the methylamine, CH(3)NH(2), molecule are considered and the novel feature that was revealed is that the two lowest states 1A(') and 1A(") are coupled by a line of cis located in HC-NHH plane-a line that is formed by moving a single hydrogen on that plane while fixing the (six) other atoms.
Preliminary results of evaluation of progress in chemotherapy for childhood leukemia patients employing Fourier-transform infrared microspectroscopy and cluster analysis☆
Jagannathan Ramesh,Mahmoud Huleihel,Jacov Mordehai,Asher Moser,Vitaly Erukhimovich,Chen Levi,Joseph Kapelushnik,Shaul Mordechai +7 more
TL;DR: Preliminary results indicated that the biological marker derived from the spectra did not provide accurate prediction of the progress made with chemotherapy, but cluster analysis of FTIR-MSP spectra provided good classification of the samples with and without blasts, which correlate satisfactorily with clinical data.

Quantum Tunneling of Hydrogen Atom in Dissociation of Photoexcited Methylamine
TL;DR: The probability of hydrogen atom release, following photoexcitation of methylamine, CH(3)NH(2), is found to increase extensively as higher vibrational states on the first excited electronic state are accessed, implying that N-H bond breaking is dominated by quantum tunneling.
