The detection and identification of organic molecules on Mars are of primary importance to establish the existence of a possible ancient prebiotic chemistry or even biological activity. The harsh environmental conditions at the surface of Mars could explain why the
Influence of Benzenecarboxylic Acids, Particularly Mellitic Acid, on Biological in vitro Systems. In a first part of the present paper influences of mellitic acid and some other benzenecarboxylic acids on reduplication of Ehrlich ascites tumor cells cultured in vitro are
A short, 14-amino-acid segment called SP1, located in the Gag structural protein1, has a critical role during the formation of the HIV-1 virus particle. During virus assembly, the SP1 peptide and seven preceding residues fold into a six-helix bundle, which
Sensory and regulatory domains allow bacteria to adequately respond to environmental changes. The regulatory ACT (Aspartokinase, Chorismate mutase and TyrA) domains are mainly found in metabolic-related proteins as well as in long (p)ppGpp synthetase/hydrolase enzymes. Here, we investigate the functional role
Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 86, 320-327 (2011-11-15)
The development of miniaturized Raman instrumentation is in demand for applications relevant to forensic, pharmaceutical and art analyses, as well as geosciences, and planetary exploration. In this study we report on evaluation of a portable dispersive Raman spectrometer equipped with
