Surface Physicochemical Properties of Globulin-P Amaranth Protein
(American Chemical Society, 2004)
Nitric oxide is required for the auxin-induced activation of NADPH-dependent thioredoxin reductase and protein denitrosylation during root growth responses in arabidopsis
(Oxford University Press, 2015-06)
Background and Aims: Auxin is the main phytohormone controlling root development in plants. This study uses pharmacological and genetic approaches to examine the role of auxin and nitric oxide (NO) in the activation of ...
Sunflower storage proteins are transported in dense vesicles that contain proteins homologous to the pumpkin vacuolar sorting receptor PV 72
(Pontificia Universidad Católica de Valparaíso, 2006-06)
Storage proteins are transported to a special storage compartments in seeds by Golgi dependent or independent pathways depending on the plant species. The aim of this work was to study the sunflower storage protein transport ...
Chloroplasts as a nitric oxide cellular source: Effect of reactive nitrogen species on chloroplastic lipids and proteins
(American Society of Plant Biologist, 2006-11)
Nitric oxide (NO) generation by soybean (Glycine max var. ADM 4800) chloroplasts was studied as an endogenous product assessed by the electron paramagnetic resonance spin-trapping technique. Nitrite and L-arginine (Arg) ...
Gelation of cowpea proteins by high hydrostatic pressure
(Elsevier, 2020-07)
The gelation of isolated cowpea protein induced by high hydrostatic pressure (HHP, 400 or 600 MPa) was studied in terms of rheological behavior, texture, color, water holding capacity (WHC), scanning electron microscopy ...
Characterization of Junín virus particles inactivated by a zinc finger-reactive compound
(Elsevier Science, 2009-07)
Our previous studies reported the inhibitory action against arenaviruses of antiretroviral zinc finger-reactive compounds provided by the National Cancer Institute (USA). These compounds were able to inactivate virions as ...
Meta-analytic evidence for increased low-grade systemic inflammation and oxidative stress in hypothyroid patients: Can levothyroxine replacement therapy mitigate the burden?
(Springer, 2020-09)
Purpose: This series of meta-analyses were aimed to elucidate the impact of hypothyroidism on low-grade systemic inflammation and oxidative stress assessed by C-reactive protein (CRP) and malondialdehyde (MDA) respectively; ...
Photochemistry of tyrosine dimer: when an oxidative lesion of proteins is able to photoinduce further damage
(Royal Society of Chemistry, 2019-04)
The tyrosine dimer (Tyr2), a covalent bond between two tyrosines (Tyr), is one of the most important modifications of the oxidative damage of proteins. This compound is increasingly used as a marker of aging, stress and ...
Free radical-operated proteotoxic stress in macrophages primed with lipopolysaccharide
(Elsevier Science Inc., 2012-07)
The free-radical-operated mechanism of death of activated macrophages at sites of inflammation is unclear, but it is important to define it in order to find targets to prevent further tissue dysfunction. A well-defined ...
Expression of a plastid-targeted flavodoxin decreases chloroplast reactive oxygen species accumulation and delays senescence in aging tobacco leaves
(Frontiers Research Foundation, 2018-07)
Leaf senescence is a concerted physiological process involving controlled degradation of cellular structures and reallocation of breakdown products to other plant organs. It is accompanied by increased production of reactive ...
