Dispersion curves for the polyglycine I chain are calculated both in-plane and out-of-plane modes of vibration, force constants fitted by comparison with observed infrared frequencies. Frequency distributions II from inelastic neutron scattering. The intensity difference C–N torsional band between suggests presence additional C–H···O-type hydrogen bonding chains in helical (II) form. An estimate sum conformational lattice energy two forms is made.

Aluminum phosphide (AlP) poisoning has a high mortality rate despite intensive care management, primarily because it causes severe myocardial depression and acute respiratory distress syndrome. The purpose of this study was to evaluate the impact novel use extracorporeal membrane oxygenation (ECMO), modified “heart-lung” machine, in specific subset AlP patients who had profound dysfunction along with either metabolic acidosis and/or refractory cardiogenic shock. Between January 2011...

Background: Aluminium phosphide (AlP) poisoning is associated with a high mortality rate when patients are complicated myocardial dysfunction and refractory shock or severe metabolic acidosis. We studied the role of veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) in AlP induced dysfunction.Methods results: This tertiary care, single-centre, retrospective study. Between January 2011 June 2016, total 107 were identified those 67 categorised high-risk category as per criteria. The...
