Exploring Centrin targets: KRR1, and the Centrin-SFI1p21 complex salt-bridge interaction
(2015)
Centrins are small calcium binding proteins and ubiquitous centrosome components. Centrins play a fundamental role in the structure and function of centrioles, basal bodies, primary cilia and the microtubule-organizing ...
Experimental and Dft Studies of the mechanism of cetone-peroxide formation reaction using Raman and nuclear magnetic resonance spectroscopies
(2009)
A mechanism for the reaction between acetone and hydrogen peroxide leading to the formation of the important homemade explosive Acetone Peroxide is postulated. The proposed mechanistic scheme is based on Raman and Nuclear ...
Dependence of active mode remote Ft-Ir sensing on angle of incidence, substrate type and analyte surface concentration
(2013-12)
A standoff detection scheme for a highly energetic material (HEM) and other threat chemicals deposited on substrates as contamination residues using Fourier transform infrared spectroscopy (FTIR) is described. The HEM used ...
A new tandem strategy for the synthesis of α,β-epoxyketones from terminal alkynes
(2019-05-15)
Because of its unique reactivity profile and synthetic utility, epoxides have captivated and attracted the organic chemistry community since their discovery. They are valuable precursors of many bioactive natural and ...
Synthesis and characterization of copper nanoparticles: Architectural morphologies and applications in surface enhanced raman spectroscopy
(2009)
The preparation of copper colloidal suspensions was conducted by three different methods. These methods used wet chemical synthesis, in which a metal salt solution was mixed with a solution containing the reducing agent. ...
A diffuse reflectance NIR spectroscopy method for determine drug concentration in pharmaceutical production tablets based on a PLS calibration model from manufactured tablets
(2018-05)
A diffuse reflectance near-infrared (NIR) spectroscopy method was developed to determine the active pharmacological ingredient (API) in pharmaceutical production tablets from batch and continuous manufacturing processes.
Tablets ...
Captura de fluoroquinolonas por Leucaena Leucocephala: Estudios electroquímicos y cromatográficos
(2017)
La contaminación del agua por antibióticos es un serio problema ambiental. El mal manejo de los medicamentos no utilizados y la descarga a través de los residuos corporales aumentan este problema, especialmente porque la ...
Effect of the E11 amino acid on the ligand binding in Hemoglobin I from Lucina pectinata
(2007)
Hemoglobin I (HbI) from Lucina pectinata (clam) is a protein that binds and transports H2S to the bacteria in the clam. HbI is one of the few known hemoglobins that carries H2S, toxic gas, in its active site, which contains ...
Effect of the Histidine E7 amino acid in the sulfheme formation of the hemoglobin I from Lucina Pectinata
(2008)
Sulfhemoglobin is a non-functional derivative of hemoglobin known to be produced by exposure to sulfa drugs, air pollution and others. It is formed by the reaction between H2O2, H2S and the heme group in the presence of ...
Electrochemical redox process analysis of Cu+2 and Fe+3 ions in natural waters using cyclic voltammetry technique
(2012-12)
The concentration and distribution of trace metals in natural water is important in order to have a better understanding of their biogeochemical behavior and natural cycles. This biological behavior and natural cycles are ...
