Genotoxicity induced by Roundup® (Glyphosate) in tegu lizard (Salvator merianae) embryos
(Academic Press Inc Elsevier Science, 2016-06)
Environmental contaminants produce multiple adverse consequences at individual, population and ecosystem levels. High volumes of agrochemicals applied to great variety of crops, together with agricultural expansion, generate ...
Structural analysis of a natural apolipoprotein A-I variant (L60R) associated with amyloidosis
(Elsevier Science Inc., 2020-05-30)
The reason that determines the pathological deposition of human apolipoprotein A-I variants inducing organ failure has been under research since the early description of natural mutations in patients. To shed light into ...
Immobilization of Carboxypeptidase A into Modified Chitosan Matrixes by Covalent Attachment
(Humana Press, 2018-08)
Carboxypeptidase A (CPA) is a metalloexopeptidase that catalyzes the hydrolysis of the peptide bonds that are adjacent to the C-terminal end of a polypeptide chain. The enzyme preferentially cleaves over C-terminal L-amino ...
Alterations in folliculogenesis in women with polycystic ovary syndrome
(Pergamon-Elsevier Science Ltd, 2011-03)
The objective of the present study was to examine some factors involved in follicular development of women with polycystic ovary syndrome (PCOS). Women with PCOS showed increased levels of serum luteinizing hormone (LH) ...
Antioxidant defenses, longevity and ecophysiology of South American bats
(Elsevier Science Inc., 2007-12)
Microchiropteran bats sustain very high oxygen consumption rates when active, but they also exhibit drastic daily drops in oxygen consumption when torpid. In addition, bats are also characterized by an extraordinary longevity ...
Cross-talk between rapid and long term effects of progesterone on vascular tissue
(Pergamon-Elsevier Science Ltd, 2009-05)
We tested the hypothesis whether; the non-genomic action of progesterone (Pg) on vascular tissue would be associated with hormonal long term effect on the modulation of cell growth. Using rat aortic strips, we showed that ...
B. cereus phospholipase C engineering for efficient degumming of vegetable oil
(Elsevier, 2017-03)
Enzymatic phospholipid removal (degumming) is a fast-growing and environmentally friendly process for vegetable oil refining. Type C phospholipases (PLC) are the preferred enzymes since they provide an extra yield in the ...
Sucrose may play a different role other than osmoprotectant in Synechocystis sp. PCC 6803 salt-shock cells
(Elsevier France-editions Scientifiques Medicales Elsevier, 2005-02)
The role of sucrose in cyanobacteria is still not fully understood. It is generally considered a salt-response molecule, and particularly, in Synechocystis sp. strain PCC 6803, it is referred as a secondary osmolyte. We ...
Heterologous production and characterization of a thermostable GH10 family endo-xylanase from Pycnoporus sanguineus BAFC 2126
(Elsevier, 2018-04)
Xylanases are key enzymes for agricultural biomass saccharification for the production of cellulosic ethanol. Success in enzymatic lignocellulose bioconversion is restricted by enzyme production costs, activity and stability ...
Differential activities of the multixenobiotic resistance mechanism in freshwater fishes inhabiting environments of Patagonia Argentina
(Elsevier Science Inc, 2019-03)
Environmental impairment resulted from urbanizations can produce damage on freshwater species including strong physiological effects at individual or population level. The multixenobiotic resistance (MXR) is a defence ...
