Absence of Light Exposure Increases Pathogenicity of Pseudomonas aeruginosa Pneumonia-Associated Clinical Isolates

Biology, 2021
Pseudomonas aeruginosa can alter its lifestyle in response to changes in environmental conditions. The switch to a pathogenic host-associated lifestyle can be triggered by the luminosity settings, resorting to at least one photoreceptor which senses ...

DNA-Interactive and Damage Study with meso-Tetra(2-thienyl)porphyrins Coordinated with Polypyridyl Pd(II) and Pt(II) Complexes

Molecules, 2023
We report the DNA-binding properties of three porphyrins with peripheral thienyl substituents (TThPor, PdTThPor and PtTThPor). The binding capacity of each porphyrin with DNA was determined by UV-Vis and steady-state fluorescence emission spectroscopy ...

The effect of a topically-applied cosmetic oil formulation on striae distensae

South African Family Practice, 2009
Background: Stretch marks or striae distensae are tears in the dermis, above which the epidermis remains intact. Striae result from rapid expansion of the underlying tissue, e.g. during puberty, pregnancy or rapid weight gain. The prevalence of striae is

Regulation of monocot and dicot plant development with constitutively active alleles of phytochrome B

Plant Direct, 2020
The constitutively active missense allele of Arabidopsis phytochrome B, AtPHYBY276H or AtYHB, encodes a polypeptide that adopts a light‐insensitive, physiologically active conformation capable of sustaining photomorphogenesis in darkness.

Phytochrome B and REVEILLE1/2-mediated signalling controls seed dormancy and germination in Arabidopsis

Nature Communications, 2016
Seed dormancy prevents germination under adverse environmental conditions. Here the authors show that the RVE1 and RVE2 transcription factors suppress biosynthesis of the germination-promoting hormone GA and act downstream of phytochrome signalling to ...

Effects of Low-Level Artificial Light at Night on Kentucky Bluegrass and an Introduced Herbivore

Frontiers in Ecology and Evolution, 2021
Increasing evidence suggests that artificial light at night (ALAN) can negatively impact organisms. However, most studies examine the impacts of ALAN on a single species or under high levels of artificial light that are infrequent or unrealistic in urban

Experimental Techniques to Assess Coral Physiology in situ Under Global and Local Stressors: Current Approaches and Novel Insights

Frontiers in Physiology, 2021
Coral reefs are declining worldwide due to global changes in the marine environment. The increasing frequency of massive bleaching events in the tropics is highlighting the need to better understand the stages of coral physiological responses to extreme ...

Effects of Glyphosate-Based Herbicide on Primary Production and Physiological Fitness of the Macroalgae Ulva lactuca

Toxics, 2022
The use of glyphosate-based herbicides (GBHs) worldwide has increased exponentially over the last two decades increasing the environmental risk to marine and coastal habitats. The present study investigated the effects of GBHs at environmentally relevant

Lactoferrin Has a Therapeutic Effect via HIF Inhibition in a Murine Model of Choroidal Neovascularization

Frontiers in Pharmacology, 2020
BackgroundLactoferrin, a type of glycoprotein, is contained in exocrine fluids such as tears, breast milk, sweat, and saliva, and is known to have anti-microbial, antioxidant, and anti-cancer effects. In the ophthalmological field, topical administration
