The aim of this in vitro study was to analyze the effect of photobiomodulation therapy (PBMT) on the proliferation and undifferentiating status of stem cell from human exfoliated deciduous teeth (SHEDs). PBMT was carried out with an aluminum gallium indium phosphide (InGaAlP) diode laser in contact and punctual mode (continuous wave, 660 nm, 20 mW, 0.028 cm2, and average energy densities of 1 (1 s),...
Seasonal coat colour change is an important adaptation to seasonally changing environments but the evolution of this and other circannual traits remains poorly understood. In this study, we use gene expression to understand seasonal coat colour moulting in wild snowshoe hares (Lepus americanus). We used hair colour to follow the progression of the moult, simultaneously sampling skin from three moulting...
Burkholderia cepacia complex bacteria are opportunistic pathogens, causing severe lung infections in cystic fibrosis patients. Many clinical isolates produce the exopolysaccharide cepacian, believed to be an infection persistence determinant. Little is known about cepacian biosynthesis regulation, but our studies showed the importance of post-translational mechanisms mediated by tyrosine phosphorylation,...
