Effects of ultraviolet radiation on metabolic rate and fitness of Aedes albopictus and Culex pipiens mosquitoes [PDF]

PeerJ, 2018
Natural and anthropogenic changes (e.g., land use change, pollution) will alter many environmental factors in the coming years, including the amount of solar radiation reaching the earth’s surface.

Variation of Saturn's UV aurora with SKR phase [PDF]

, 2010
peer reviewedIt is well known that a wide range of kronian magnetospheric phenomena, including the Saturn kilometric radiation (SKR), exhibit oscillations near the planetary rotation period.

The sensitivity of sunflower (Helianthus annuus L.) plants to UV-B radiation is altered by nitrogen status

Ciência Rural, 2018
: Interaction effects between nitrogen and UV-B radiation were studied in sunflower (Helianthus annuus L. variety IAC-Iarama) plants grown in a greenhouse under natural photoperiod conditions.

Terrestrial ecosystems, increased solar ultraviolet radiation and interactions with other climatic change factors

, 2007
Based on research to date, we can state some expectations about terrestrial ecosystem response as several elements of global climate change develop in coming decades.

Effect of solar and artificial UV radiation on photosynthetic performance and carbonic anhydrase activity in intertidal macroalgae from southern Spain

Ciencias Marinas, 2009
The effect of UV radiation on photosynthetic rate and carbon uptake, estimated as carbonic anhydrase activity, was studied by incubating intertidal algae, Fucus spiralis (Phaeophyta) and Ulva olivascens (Chlorophyta), under both artificial and solar ...

Balancing the solar irradiance needs: optimising growth in sphagnum palustre through tailored UV-B effects

BMC Plant Biology
Background The carbon sequestration potential and water retention capacity of peatlands are closely linked to the growth dynamics of Sphagnum mosses. However, few studies have focused on the response of Sphagnum moss growth dynamics to UV-B radiation ...

Response of barley and pea crops to supplementary UV-B radiation. [PDF]

, 1999
Four cultivars of winter barley (Hordeum vulgare L.) and two cultivars of combining pea (Pisum sativum L.) were grown in the field in the UK (52°N) and irradiated under banks of UV-B lamps in 1994/95 (barley) and 1996 (pea).

UV-B exposure, ROS, and stress: inseparable companions or loosely linked associates?

, 2013
Ultraviolet-B (UV-B) radiation has long been perceived as a stressor. However, a conceptual U-turn has taken place, and UV-B damage is now considered rare.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
