Analysis of phthalic acid, bisphenol A and bisphenol A dimethacrylate in Mexican food cans by HPLC with evaporative light scattering detector
(2013-06)"Bisphenol A (BPA), bisphenol A dimethacrylate (BisDMA) and phthalic acid (PA) endocrine disruptors can migrate from the plastic lining of cans to foods producing serious health problems when they exceed allowable concentration ... -
Isolation and phylogenetic classification of culturable psychrophilic prokaryotes from the Collins glacier in the Antarctica
(2011-05)"Culturable psychrophilic prokaryotes were obtained of samples of glacier sediment, seaside mud, glacier melted ice, and Deschampsia antarctica rhizosphere from Collins glacier, Antarctica. The taxonomic classification was ... -
Expansion of human hematopoietic stem cells for transplantation: trends and perspectives
(2008-03)"Umbilical cord blood transplantation is clinically limited by its low progenitor cell content. Ex vivo expansion has become an alternative to increase the cell dose available for transplants. Expansion has been evaluated ... -
Optimization of fermentation conditions for the production of the mezcal from Agave salmiana using response surface methodology
(Elsevier, 2008-01)"Response surface methodology was applied to optimize the fermentative phase for the mezcal production from Agave salmiana. A 3k factorial design was used to obtain models describing the relationship between the ethanol ... -
Phthalates and bisphenols migration in Mexican food cans and plastic food containers
(2011-06)"The presence of endocrine disruptors bisphenol-A, bisphenol-A-dimethacrylate, bisphenol-A-diglycidyl-ether, phthalic-acid, dibutyl-phthalate, diethyl-phthalate and dioctyl-phthalate was determined in vegetable cans, baby ... -
Optimization of human interferon gamma production in Escherichia coli by response surface methodology
(2008-02)"The production of human interferon gamma (hIFN-γ) using a synthetic gene in Escherichia coli BL21-SI was optimized by response surface methodology (RSM) and a Box-Behnken design. The process variables studied were ... -
Modified penicillin acylase signal peptide allows the periplasmic production of soluble human interferon-γ but not of soluble human interleukin-2 by the Tat pathway in Escherichia coli
(2007-09)"Production of periplasmic human interferon-γ (hINF-γ) and human interleukin-2 (hIL-2) by the Tat translocation pathway in Escherichia coli BL21-SI was evaluated. The expression was obtained using the pEMR vector which ... -
Optimization of culture conditions for a synthetic gene expression in Escherichia coli using response surface methodology: the case of human interferon beta
(Elsevier, 2007-06)"A human interferon beta (hINF-β) synthetic gene was optimized and expressed in Escherichia coli BL21-SI using a vector with the T7 promoter. To determine the best culture conditions such as culture medium, temperature, ... -
Fermentation of lactose and its constituent sugars by Escherichia coli WDHL: impact on hydrogen production
(Elsevier, 2012-05)"Fermentations of lactose, glucose and galactose using Escherichia coli WDHL, a hydrogen over producer strain, were performed. With glucose as substrate pyruvate was mainly routed to the lactate pathway, resulting in ... -
