Inactivation kinetics of some microorganisms in apple, melon, orange and strawberry juices by high intensity light pulses
(Elsevier, 2013-10)
The suitability of some models was analyzed to characterize the Pulsed Light (PL) inactivation kinetics for Escherichia coli ATCC 35218, Listeria innocua ATCC 33090, Salmonella Enteritidis MA44 and Saccharomyces cerevisiae ...
Factors determining the variation in birth weight in Spain (1980- 2010)
(Taylor & Francis, 2013-06)
Background: Low weight and premature deliveries arouse clinical interest concerning the survival of newborns. The determinants of birth weight among Spanish natives and immigrants may differ. Research which considers ...
Optimization of cellular uptake of zinc(II) 2,9,16,23-tetrakis[4-(N-methylpyridyloxy)]phthalocyanine for maximal photoinactivation of Candida albicans
(Elsevier, 2013-09)
Cellular uptake and photodynamic action of zinc(II) 2,9,16,23-tetrakis[4-(N-methylpyridyloxy)]phthalocyanine (ZnPPc4+) was examined in Candida albicans. In vitro investigations showed that ZnPPc4+ was rapidly bound to C. ...
A SEM-based assessment of bioerosion in Late Holocene faunal bone assemblages from the southern Pampas of Argentina
(Elsevier, 2018-04)
Over the last decades, research on microbial bioerosion affecting archaeological bone assemblages highlighted the fact that this is a significant factor determining the long-term survival of vertebrate hard tissues as well ...
Phytoextraction of Pb, Cr, Ni, and Zn using the aquatic plant Limnobium laevigatum and its potential use in the treatment of wastewater
(Springer Heidelberg, 2017-06)
In order to study the bioaccumulation of Pb, Cr, Ni, and Zn and the stress response, the floating aquatic plant Limnobium laevigatum was exposed to increasing concentrations of a mixture of these metals for 28 days, and ...
An Antibody-based Multifaceted Approach Targeting the Human Transferrin Receptor for the Treatment of B-cell Malignancies
(Lippincott Williams, 2011-11)
We previously developed an antibody-avidin fusion protein (ch128.1Av) targeting the human transferrin receptor 1 (TfR1, also known as CD71), which demonstrates direct in vitro cytotoxicity against malignant hematopoietic ...
Lactococcus lactis SpOx spontaneous mutants: A family of oxidative-stress-resistant dairy strains
(American Society for Microbiology, 2005-05)
Numerous industrial bacteria generate hydrogen peroxide (H 2O2), which may inhibit the growth of other bacteria in mixed ecosystems. We isolated spontaneous oxidative-stress-resistant (SpOx) Lactococcus lactis mutants by ...
Development of a cell line from Echinococcus granulosus germinal layer
(Elsevier Science, 2013-07)
In vitro culture of parasitic helminths provides an important tool to study cell regeneration and physiology, as well as for molecular biology and genetic engineering studies. In the present study, we established in vitro ...
Environmental selection pressures related to iron utilization are involved in the loss of the Flavodoxin Gene from the plant genome
(Oxford University Press, 2015-03)
Oxidative stress and iron limitation represent the grim side of life in an oxygen-rich atmosphere. The versatile electron transfer shuttle ferredoxin,aniron-sulfurprotein,isparticularlysensitivetothesehardships,anditsdow ...
Global changes in pampean lowland streams (Argentina): Implications for biodiversity and functioning
(Springer, 2010-10)
The rivers and streams in the pampean plains are characterized by a low flow rate due to the low slope of the surrounding terrain, high levels of suspended solids, silty sediment in the benthos, and reduced rithron; the ...
