Femtosecond spectroscopy studies of recombinant hemoglobin I of the clam Lucina pectinata (Gmelin, 1791)
(2011)
Lucina pectinata (Gmelin, 1791) is a clam that can be found in sulfide-rich muds in the
coastal mangroves of the southwest coast of Puerto Rico. It contains three different
hemoglobins in the gill tissue, hemoglobin I, ...
Sulfheme formation mechanism and spectra analysis using QM/MM and TDDFT
(2018-05)
Since the 1863 discovery of a new green hemoglobin derivative called “sulfhemoglobin”, the
nature of its characteristic 618 nm absorption band and formation mechanism has been the subject of
several hypotheses. Many ...
Removal and speciation of oxyanions from aqueous solutions using Ca-Fe(III) alginate beads and dried sludge as adsorbents
(2013)
Oxyanions are highly soluble species, which are pH and redox dependant, and represent a toxic and hazardous species to humans and for the environment. Various remediation techniques have been applied such as: precipitati ...
Synthesis, characterization and mild detemplation of novel cobalt rich SBE type nanoporous materials
(2012)
The optimization of the synthesis, extended characterization and evaluation of the adsorption properties of cobalt-rich SBE type aluminophosphates (CoAPO-SBE) were investigated. According to X-ray diffraction (XRD), scanning ...
Design and development of remote Raman spectroscopy system for detection of hazardous compounds
(2012-11)
Remote Raman detection has become a powerful analytical technique for detection of hazardous compounds in situ and without sample preparation at distances away from the observation site. This study describes the design, ...
Structural characterization of the oxygen reactive heamoglobins from the clam Lucina pectinata
(2014)
Hemoglobins comprise a challenging area of study within biochemical research. They play an
important physiological role in organisms, like oxygen transport and storage. Three hemoglobins were discovered in the ctenidia ...
Biomedical applications of nanotechnology : exploratory research on the use of one dimensional nanostructures
(2016)
Studies related to the use of nanoscaled materials in biomedical science and engineering research is at the forefront of research in medicine. Applied research in nanotechnology, particularly as related to medicine, is ...
Size controlled synthesis of metallic magnetic nanocrystals for potential data storage and biomedical applications
(2013)
Magnetic nanoparticles have attracted extensive interest in recent years due to their potential applications as a consequence of their tunable magnetic properties. Therefore, research efforts are focused on the development ...
Sulfmyoglobin formation pathway upon reaction of oxy-myoglobin and hydrogen sulfide
(2019-12-03)
Myoglobin (Mb) binds oxygen with high affinity as a low spin singlet complex and thus functions as an oxygen storage protein. Quantum chemical calculations of oxy-Mb models with hydrogen sulfide (H2S) in the active site ...
Structural aspects and chemical species involved in the hemeperoxidases catalytic oxidation of hydrogen sulfide by hydrogen peroxide and oxygen
(2018)
Hydrogen sulfide (H2S) has gained attention since it is implied in human physiological functions with potential therapeutically effects. Furthermore, H2S interacts with physiologically important hemeproteins such as ...
