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 ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The Effect of Increased UV-B Radiation on the Terrestrial Ecosystem

Turkish Journal of Agriculture: Food Science and Technology, 2019
Against rapidly developing industry and increasing population, natural resources on earth are getting destroyed. One of the most important adverse effects on the environment is perhaps the depletion of ozone layer which protects the earth from harmful ...

Solar ultraviolet-B radiation and vitamin D: a cross-sectional population-based study using data from the 2007 to 2009 Canadian Health Measures Survey [PDF]

, 2012
Background: Exposure to solar ultraviolet-B (UV-B) radiation is a major source of vitamin D3. Chemistry climate models project decreases in ground-level solar erythemal UV over the current century.

Photosystems activities and polypeptide composition of Cyamopsis tetragonoloba and Vigna mungo thylakoids as affected by exclusion of solar UV radiation

Biologia Plantarum, 2010
The impacts of solar UV (280-400 nm) radiation on photosynthetic activities and polypeptide composition of thylakoids of cluster bean (Cyamopsis tetragonoloba L, UV-B sensitive) and black gram (Vigna mungo L., UV-B resistant) plants were compared.

Photoreceptors UVR8 and phytochrome B cooperate to optimize plant growth and defense in patchy canopies [PDF]

, 2015
Light is a critical source of information for plants. Plants use the phytochromes (particularly phyB) to detect light signals associated with the proximity of competitors.

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.
