DEVDase activity is induced in potato leaves during Phytophthora infestans infection
(Elsevier France-editions Scientifiques Medicales Elsevier, 2012-12)
Programmed cell death (PCD) occurs in plants, animals and several branches of unicellular eukaryotes as a part of developmental and/or defense processes. Caspase proteases are universal mediators of animal apoptosis, a ...
Stem canker caused by Phomopsis spp. induces changes in polyamine levels and chlorophyll fluorescence parameters in pecan leaves
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021-06)
Pecan plants are attacked by the fungus Phomopsis spp. that causes stem canker, a serious and emerging disease in commercial orchards. Stem canker, which has been reported in several countries, negatively affects tree ...

Involvement of hnRNP A1 in the matrix metalloprotease-3-dependent regulation of Rac1 pre-mRNA splicing
(Wiley-liss, Div John Wiley & Sons Inc, 2012-07)
Rac1b is an alternatively spliced isoform of the small GTPase Rac1 that includes the 57-nucleotide exon 3b. Rac1b was originally identified through its over-expression in breast and colorectal cancer cells, and has ...
The relationship between oxygen consumption and body acceleration in a range of species
(Elsevier Science Inc, 2009-02)
The ability to measure the energy expenditure of free-ranging animals is of great importance but the techniques available each have their limitations. Recently, as an alternative to more established techniques, an integrated ...
Phospholipid changes in Rhinella arenarum embryos under different acclimation conditions to copper
(Elsevier Science Inc, 2016-11)
We report phospholipid changes in Rhinella arenarum embryos after applying three acclimation protocols to copper between 40 and 420 ng L− 1. The lower and higher acclimation treatments resulted in embryos' enhanced resistance ...
Phytomodulatory effects of silver nanoparticles on Corchorus olitorius: Its antiphytopathogenic and hepatoprotective potentials
(Elsevier France-editions Scientifiques Medicales Elsevier, 2019-03)
This study has reported the effects of biogenic silver nanoparticles (AgNPs) using cocoa pod extract on physiological tolerance indices, antioxidant activity and hepatoprotective potentials of Corchorus olitorius as well ...
Precipitation with poly acrylic acid as a trypsin bioseparation strategy
(Elsevier, 2009-09)
Precipitation of enzymes with reversible soluble-insoluble polymers is a simple approach which can be easily scaled up. This work reports investigations aiming at verifying the existence of specific interactions and complex ...
Preparation, characterization and activity of CuZn and Cu2 superoxide dismutase mimics encapsulated in mesoporous silica
(Elsevier Science Inc, 2020-06)
Encapsulation of three superoxide dismutase (SOD) functional mimics, [CuZn(dien)2(μ-Im)(ClO4)2]ClO4 (1), [Cu2(dien)2(μ-Im)(ClO4)2]ClO4 (2) (Im = imidazolate, dien = diethylenetriamine), and [CuZn(salpn)Cl2] (3) (H2salpn = ...
Zinc(II) phthalocyanines as photosensitizers for antitumor photodynamic therapy
(Pergamon-Elsevier Science Ltd, 2019-09)
Photodynamic therapy (PDT) is a highly specific and clinically approved method for cancer treatment in which a nontoxic drug known as photosensitizer (PS) is administered to a patient. After selective tumor irradiation, ...
