Nitrogen-limitation exacerbates the impact of ultraviolet radiation on the coccolithophore Gephyrocapsa oceanica.

Journal of photochemistry and photobiology. B, Biology

J Photochem Photobiol B. 2021 Nov 23;226:112368. doi: 10.1016/j.jphotobiol.2021.112368. Epub 2021 Nov 23.

To investigate effects of UV radiation (UVR, 280-400 nm) on coccolithophorids under nutrient-limited conditions, we grew Gephyrocapsa oceanica to determine its resilience to consecutive daily short-term exposures to +UVR (irradiances >295 nm) under a range of nitrate availabilities (100,...

Novel amphibian-derived antioxidant peptide protects skin against ultraviolet irradiation damage.

Journal of photochemistry and photobiology. B, Biology

Given the adverse impact of ultraviolet irradiation on human skin, as well as currently limited interventions, the discovery of new molecules with anti-photodamage potency remains critical. In this research, we obtained a new bioactive peptide (named OS-LL11, amino acid...

Investigating the cellular responses of osteosarcoma to cisplatin by confocal Raman microspectroscopy.

Journal of photochemistry and photobiology. B, Biology

Wang H, Li J, Qin J, Li J, Chen Y, Song D, Zeng H, Wang S.

J Photochem Photobiol B. 2021 Nov 19;226:112366. doi: 10.1016/j.jphotobiol.2021.112366. Epub 2021 Nov 19.

Confocal Raman Microspectroscopy (CRM) was employed to clarify the cellular response of cisplatin in osteosarcoma (OS) cells with different dosages and incubation times. The K7M2 mouse osteosarcoma cells were treated by cisplatin in 0 μM (UT group), 20 μM...

Production and viscosity of Xanthan Gum are increased by LED irradiation of X. campestris cultivated in medium containing produced water of the oil industry.

Journal of photochemistry and photobiology. B, Biology

Crugeira PJL, de Almeida PF, Sampaio ICF, Soares LGP, Moraga Amador DA, Samuel IDW, Persheyev S, Silveira L, Pinheiro ALB.
PMID: 34801926
J Photochem Photobiol B. 2021 Nov 12;226:112356. doi: 10.1016/j.jphotobiol.2021.112356. Epub 2021 Nov 12.

Oil recovery is a challenge and microbial enhanced oil recovery is an option. We theorized that the use of produced water (PW) with photo-stimulation could influence both production and viscosity of Xanthan gum. This study aimed at the evaluation...
