Mechanisms of growth inhibition of primary prostate epithelial cells following gamma irradiation or photodynamic therapy including senscence, necrosis, and autophagy, but not apoptosis [PDF]

open access: yes, 2015
In comparison to more differentiated cells, prostate cancer stem-like cells are radioresistant, which could explain radio-recurrent prostate cancer. Improvement of radiotherapeutic efficacy may therefore require combination therapy.

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Towards a long-term record of solar total and spectral irradiance [PDF]

open access: yesJournal of Atmospheric and Solar-Terrestrial Physics, 2011, Volume 73, Issue 2-3, p. 223-234, 2009
The variation of total solar irradiance (TSI) has been measured since 1978 and that of the spectral irradiance for an even shorter amount of time. Semi-empirical models are now available that reproduce over 80% of the measured irradiance variations. An extension of these models into the more distant past is needed in order to serve as input to climate ...

Pursuing the precision study for Color Glass Condensate framework in forward single hadron productions [PDF]

open access: yesEPJ Web of Conferences
The forward single hadron production process is an important benchmark process for investigating the emergent properties of gluon saturation or the dense gluon system. We present our recent work [1] in which we improve the prediction accuracy of the next-

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair

open access: yesFEBS Letters, EarlyView.
miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Photoactivation of trans diamine platinum complexes in aqueous solution and effect on reactivity towards nucleotides [PDF]

open access: yes, 2010
We show that UVA irradiation (365 nm) of the Pt-IV complex trans,trans,trans-[(PtCl2)-Cl-IV(OH)(2)(dimethylamine) (isopropylamine)] (1), induces reduction to Pt-II photoproducts.

Brucella NyxA and NyxB dimerization enhances effector function during infection

open access: yesFEBS Letters, EarlyView.
Brucella abortus thrives inside cells thanks to the translocation of effector proteins that fine‐tune cellular functions. NyxA and NyxB are two effectors that destabilize the nucleolar localization of their host target, SENP3. We show that the Nyx proteins directly interact with each other and that their dimerization is essential for their function ...

Effect of Gamma Irradiation on Depolymerization and Property Changes of Gum Tragacanth

open access: yesInternational Journal of Biomaterials
High-energy nonthermal processes (irradiation) are an interesting technique for depolymerization. Gum tragacanth (GT) is a heteropolysaccharide composed of various sugars that are beneficial in the food and pharmaceutical industries.
