Biocompatible Germanium-Doped Hydroxyapatite Nanoparticles for Promoting Osteogenic Differentiation and Antimicrobial Activity Open
Hydroxyapatite (HAp) has been the main protagonist in the quest for an ideal biomaterial for regenerative medicine over the last half a century. To control its properties, this material has commonly been doped with chemical elements other …

Curcumin as a Perspective Protection for Retinal Pigment Epitheliumduring Autophagy Inhibition in the Course of Retinal Degeneration Open
Defective autophagy in the retinal pigment epithelium (RPE) is involved in retinal degeneration, mostly in the course of age-related macular degeneration (AMD), which is an increasingly prevalent retinal disorder, eventually leading to bli…

Combined pulses of light and sound in the retina with nutraceuticals may enhance the recovery of foveal holes Open
The present manuscript stems from evidence, which indicates that specific wavelength produce an activation of the autophagy pathway in the retina. These effects were recently reported to synergize with the autophagy-inducing properties of …

Noradrenergic substrates sensing light within brainstem reticular formation as targets for light-induced behavioral and cardiovascular plasticity Open
The occurrence of pure light exerts a variety of effects in the human body, which span from behavioral alterations, such as light-driven automatic motor activity, cognition and mood to more archaic vegetative functions, which encompass mos…

Pulsed blue light inactivates two strains of human coronavirus Open
Emerging evidence suggests that blue light has the potential to inactivate viruses. Therefore, we investigated the effect of 405 nm, 410 nm, 425 nm and 450 nm pulsed blue light (PBL) on human alpha coronavirus HCoV-229 E and human beta cor…

Structural membrane changes induced by pulsed blue light on methicillin-resistant Staphylococcus aureus (MRSA) Open
These signs of bacterial inactivation at a dose deliberately selected to be sub-lethal supports our previous finding that rapid depolarization of bacterial cell membrane and disruption of cellular function comprise another mechanism underl…

Understanding the antimicrobial activity of selected disinfectants against methicillin-resistant Staphylococcus aureus (MRSA) Open
Disinfectants and biocidal products have been widely used to combat Methicillin-resistant Staphylococcus aureus (MRSA) infections in homes and healthcare environments. Although disruption of cytoplasmic membrane integrity has been document…

Blue 470 nm light suppresses the growth of <i>Salmonella enterica</i> and methicillin‐resistant <i>Staphylococcus aureus</i> (MRSA) in vitro Open
Background and Objective Emerging evidence suggests that blue light can photo‐inactivate some bacteria of clinical importance. Consequently, we tested the hypothesis that 470 nm light can suppress growth of two recalcitrant bacteria, MRSA …

Whole-Genome Sequence for Methicillin-Resistant Staphylococcus aureus Strain ATCC BAA-1680 Open
We report here the whole-genome sequence of the USA300 strain of methicillin-resistant Staphylococcus aureus (MRSA), designated ATCC BAA-1680, and commonly referred to as community-associated MRSA (CA-MRSA). This clinical MRSA isolate is c…

Optimization of the antimicrobial effect of blue light on methicillin-resistant<i>Staphylococcus aureus</i>(MRSA)<i>in vitro</i> Open
The bactericidal effect of blue light can be optimized to yield 100% bacterial growth suppression, but with relatively high fluences for dense bacterial cultures, such as 7 × 10(6) CFU/ml.
