Climate change effects on grapevine physiology and biochemistry: Benefits and challenges of high altitude as an adaptation strategy
(Frontiers Media, 2022-04)
Grapevine berry quality for winemaking depends on complex and dynamic relationships between the plant and the environment. Winemakers around the world are demanding a better understanding of the factors that influence berry ...
Functional acclimation to solar UV-B radiation in Gunnera magellanica, a native plant species of southernmost Patagonia
(Wiley Blackwell Publishing, Inc, 2003-12)
The ecosystems of Tierra del Fuego (in southern Patagonia, Argentina) are seasonally exposed to elevated levels of ultraviolet-B radiation (UV-B: 280-315 nm), due to the passage of the 'ozone hole' over this region. In the ...
Ocean acidification exacerbates the effect of UV radiation on the calcifying phytoplankter Emiliania huxleyi
(American Society of Limnology and Oceanography, 2009-12)
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2 have been reported in the widespread coccolithophore Emiliania huxleyi. ...
Solar UV-B radiation affects leaf quality and insect herbivory in the southern beech tree Nothofagus antarctica
(Springer, 2004-03)
We examined the effects of solar ultraviolet-B (UV-B) radiation on plant-insect interactions in Tierra del Fuego (55°S), Argentina, an area strongly affected by ozone depletion because of its proximity to Antarctica. Solar ...
Effect of chronic UVR exposure on zooplankton molting and growth
(Elsevier, 2020-12)
Molting is a crucial physiological process in arthropods development, growth, and adult reproduction, where the chitinolytic enzyme chitobiase (CB) and the apoptosis process (caspase-3 activity) play crucial roles. Both ...
Arsenic (III) oxidation of water applying a combination of hydrogen peroxide and UVC radiation
(Royal Society Of Chemistry, 2011-09)
Arsenic is toxic to both plants and animals and inorganic arsenicals are proven carcinogens in humans. The oxidation of As(III) to As(V) is desirable for enhancing the immobilization of arsenic and is required for most ...
Probiotic effects on skin health: the case of photoprotection as a model of gut-skin dialog
(Springer Nature Switzerland AG, 2021)
The skin is the most external organ of our body, and it is constantly exposed to environmental challenges. In this way, ultraviolet radiation (UVr) contained within sunlight is one of the most important insults that our ...
UV-B affects the immune system and promotes nuclear abnormalities in pigmented and non-pigmented bullfrog tadpoles
(2018-03-01)
Ultra-Violet (UV) radiation is a stressor of the immune system and causes DNA damage. Leukocytes can change in response to environmental changes in anurans, making them an important biomarker of stressful situations. The ...
Text message reminders for improving sun protection habits: a systematic review
(Public Library of Science, 2020)
Background: Excessive exposure to ultraviolet radiation increases the risk of skin cancer and other conditions. SMS text reminders may be a useful tool to improve sun protection habits due to its massive reach, low cost, ...
Modeling the Infrared Reverberation Response of the Circumnuclear Dusty Torus in AGNs: The Effects of Cloud Orientation and Anisotropic Illumination
(IOP PUBLISHING LTD, 2017)
The obscuring circumnuclear torus of dusty molecular gas is one of the major components of active galactic nuclei (AGN). The torus can be studied by analyzing the time response of its infrared (IR) dust emission to variations ...
