Structure-activity studies, role of transferrin, and gene expression profile of the cytotoxic activity of Ti(IV) complexes in colon adenocarcinoma
(2008-12)
Ligand modification on titanocene dichloride has the potential to produce soluble and stable complexes. As part of our research efforts in the area of titanium-based antitumor agents, we have investigated the cytotoxic ...
The role of position E11 in the stabilization of the HbI-SH2 complex from L. pectinata
(2007)
The bivalve mollusk, Lucina pectinata, contains three hemoglobins: hemoglobin I (HbI) which is a H2S reactive protein, hemoglobin II (HbII) and hemoglobin III (HbIII) which deliver O2 to the organism. HbI is a monomeric ...
Synthesis, characterization, binding interactions with biomolecules and cytotoxic studies of molybdebocene complexes
(2009)
Bis-(cyclopentadienyl) molybdenum dichloride or molybdenocene dihalides, like other metallocenes dihalides, have shown antitumor properties in different human tumors. In contrast to titanocene dichloride, molybdenocene ...
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. ...
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 ...
Adsorption coefficients of 2,4-DNT in soils and clay minerals
(2009)
Contamination of soil and water by explosives is widespread and often caused by various military activities. 2,4-DNT is commonly used as a military explosive. This explosive may enter to the environment from the processes ...
Hemoglobin I from Lucina pectinata: A model for hydrogen sulfide reactivity within hemeproteins
(2009)
The hemoglobin I (HbI) from the clam Lucina pectinata is an intriguing hemeprotein that binds and transports H2S to chemoautotrophic bacteria to maintain a symbiotic relationship and to protect the mollusk from H2S toxicity. ...
Optical properties and energy transfer processes in silver nanocomposite glasses
(2009)
This thesis reports results on the spectroscopic properties and energy transfer processes in silver-doped aluminophosphate glasses. Material preparation was achieved by the meltquenching technique, with tin being used for ...
Caracterización química de metabolitos aislados en un extracto con actividad antimicrobiana y antifúngica de la ascidia, Rhopalaea sp. Proveniente del área de Cuajiniquil, Guanacaste, Costa Rica
(2009)
Marine ecosystems have a very large amount of resources, most of them are still partially unknown, and few have been exploited for development of new industrial and toxicological products. The objective of this investigation ...
Thermal characterization of acetone peroxide mixtures with high energetic materials and raman based detection of concealed chemical threats
(2009)
This study was aimed at making contributions toward the understanding and detection of homemade explosives (HME). The properties and interactions between components in a blend of energetic materials with acetone peroxide, ...
