Radiation Damage Mechanisms of Monolayer-Protected Nanoparticles via TEM Analysis
(American Chemical Society, 2017-11-19)
In this work, it is shown that thiol-protected Au nanoparticles (AuNPs@SR) of approximately 3.4 nm size suffered unexpectedly high radiation damage under standard transmission electron microscopy (TEM) operating conditions. ...
Dynamics of potentially protective compounds in Rhodophyta species from Patagonia (Argentina) exposed to solar radiation
(Elsevier Science Sa, 2004-07)
The impact of solar radiation upon potentially protective compounds (i.e., UV-absorbing compounds and carotenoids) was assessed in four Rhodophyte species from Patagonia (i.e., Ceramium sp. Lyngbye, Corallina officinalis ...
Black stem by Phoma macdonaldii affected ecophysiological components that determine grain yield in sunflower (Helianthus annuus L.)
(Elsevier Science, 2014-03)
Black stem (BS) of sunflower (Helianthus annuus L.) by Phoma macdonaldii has been reported in many production areas of the world associated to losses in grain yield. Their symptoms could be confounded with natural leaf ...
Protective effect of an antithyroid compound against γ-radiationinduced damage in human colon cancer cells
(Springer, 2014-04)
We have previously reported the radioprotective effect of propylthiouracil (PTU) on thyroid cells. The aim of the present study was to analyze whether tumor cells and normal cells demonstrate the same response to PTU. Human ...
Effects of solar radiation on the Patagonian Rhodophyte, Corallina officinalis (L.).
(Springer, 2003-12)
Experiments were conducted in Patagonian waters (Argentina) to assess the impact of solar radiation (PAR, 400– 700 nm, and UVR, 280–400 nm) upon two strains of the red alga Corallina officinalis Linnaeus, characteristic ...
Effects of sun exposure and vegetation cover on Woodpecker nest orientation in subtropical forests of South America
(Springer Tokyo, 2019-09-11)
Variations in the orientation behavior of Woodpecker nests can be due to environmental factors such as latitude as well as local climate conditions. In this study, the orientations of dot-fronted Woodpecker nesting cavities ...
Apigenin produced by maize flavone synthase I and II protects plants against UV-B-induced damage
(Wiley Blackwell Publishing, Inc, 2019-02)
Flavones, one of the largest groups of flavonoids, have beneficial effects on human health and are considered of high nutritional value. Previously, we demonstrated that maize type I flavone synthase (ZmFNSI) is one of the ...
The conchocelis of porphyra haitanensis (rhodophyta) is protected from harmful UV radiation by the covering calcareous matrix
(Wiley Blackwell Publishing, Inc, 2009-12)
Previous study has shown that Porphyra conchocelis is sensitive to high levels of PAR (400–700 nm) as well as ultraviolet radiation (UVR: 280–400 nm), resulting in high inhibition of photosynthesis. However, little is known ...
Catalases of the polyextremophylic Andean isolate Acinetobacter sp. Ver 3 confer adaptive response to H2O2 and UV radiation
(Wiley Blackwell Publishing, Inc, 2020-03)
The polyextremophilic strain Acinetobacter sp. Ver3 isolated from high-altitude Andean lakes exhibits elevated tolerance to UV-B radiation and to pro-oxidants, a feature that has been correlated to its unusually high ...
Patterns of nest orientation in the Golden billed Saltator (Saltator aurantiirostris) in central Argentina
(Neotropical Ornithological Society, 2018-08-17)
In birds, nest location defines the microclimatic conditions for the development of eggs and nestlings. In general, direct solar radiation and wind are the main determinants of bird nest orientation patterns. In this study, ...
