Margarita Velásquez, Darío Méndez, Carlos MonerizMay 31, 2019
The Open Biochemistry Journal is an open-access online journal dedicated to the rapid publication of original research articles, reviews/mini-reviews, letters and guest edited single topic issues in all sub-disciplines of biochemistry (including genomics, gene expression, replication, proteomics, structural biology, enzymology, bioenergetics, metabolism, signal transduction, bioinformatics, cell biology, glycoscience, glycobiology, glycochemistry, glycotechnology, pharmacology, enzyme inhibition, inhibitory processes, immunochemistry, macromolecules, biopolymers, and nitric oxide). The journal publishes clearly written articles describing significant advances in the field that are of great interest for the scientific community worldwide. Non-conclusive or confirmatory studies are not accepted.
Pyridoxine has reduction and prevention against the levels of reactive oxygen species in in vitro studies. However, the biochemical mechanism that explains this behavior has not yet been fully clarified.
To evaluate the effect of pyridoxine against oxidative damage on the membrane of human erythrocytes.
Cumene hydroperoxide was used to induce oxidative stress in protein and lipid. Human erythrocytes were incubated with pyridoxine and cumene hydroperoxide, either alone or together for 8 h. Oxidative damage was determined by measuring lipid peroxidation and membrane protein carbonylation.
The results indicate that the malondialdehyde concentration decreased with increasing concentration of pyridoxine. The membrane protein content also decreased with increasing concentration of vitamin B6, which was confirmed by the decreased signal intensity in the western blot when compared to control without pyridoxine. Results demonstrate that pyridoxine can significantly decrease lipid peroxidation and protein carbonylation in red cell membrane exposed to high concentrations of oxidant agent.
Pyridoxine showed a protective effect against the oxidative stress in human erythrocytes in vitro, inhibiting the carbonylation and the oxidative damage of erythrocyte membrane proteins. To date, such an effect has not yet been reported in terms of protein oxidation.

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."
. —Daniel Pesut. (Indiana University School of Nursing, USA)."It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."
. —Jacques Descotes. (Centre Antipoison-Centre de Pharmacovigilance, France)."Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."
. —Patrice Talaga. (UCB S.A., Belgium)."Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."
. —Jeffrey M. Weinberg. (St. Luke's-Roosevelt Hospital Center, USA)."Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."
. —Debomoy K. Lahiri. (Indiana University School of Medicine, USA)."Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."
. —Robert Looney. (Naval Postgraduate School, USA)."Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."
. —Richard Reithinger. (Westat, USA)."Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."
. —J. Ferwerda. (University of Oxford, UK)."Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."
. —Sean L. Kitson. (Almac Sciences, Northern Ireland)."In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."
. —Hubert Wolterbeek. (Delft University of Technology, The Netherlands)."The widest possible diffusion of information is critical for the advancement of science. In this perspective, open access journals are instrumental in fostering researches and achievements."
. —Alessandro Laviano. (Sapienza - University of Rome, Italy)."Open access journals are very useful for all scientists as they can have quick information in the different fields of science."
. —Philippe Hernigou. (Paris University, France)."There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."
. —Fidel Toldrá. (Instituto de Agroquimica y Tecnologia de Alimentos, Spain)."Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."
