Protective effects of extracellular vesicle‐like nanoparticles derived from Cannabis sativa adventitious roots against UVB‐induced damage in human keratinocytes

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Cannabis sativa root‐derived extracellular vesicle‐like nanoparticles (CA‐NPs) were isolated from adventitious root cultures and subjected to physicochemical characterization. Upon UVB exposure, keratinocytes exhibited increased ROS generation, apoptosis and MAPK activation, leading to oxidative stress and skin damage.

Effect of heme oxygenase-1 gene promoter polymorphism on cancer risk by histological subtype: A prospective study in arseniasis-endemic areas in Taiwan

open access: yes, 2017
Heme oxygenase (HO)-1 is upregulated by many stressful stimuli, including arsenic. A GT-repeat ((GT)n) polymorphism in the HO-1 gene promoter inversely modulates the levels of HO-1 induction. Previous HO-1 (GT)n polymorphism studies in relation to cancer

Induction of Heme Oxygenase By a Carbon Monoxide-Releasing Molecule

open access: yes, 2007
We have recently demonstrated that heme oxygenase is expressed in both healing wounds and in pressure ulcers. Heme oxygenase has been shown to have important cytoprotective functions in myocardial ischemia-reperfusion injury and organ allograft survival.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Optimization of photobiomodulation therapy for spinal cord injury: A review

open access: yesPhotochemistry and Photobiology, EarlyView.
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

The ferrous verdoheme-heme oxygenase complex is six-coordinate and low-spin

open access: yes, 2005
A biosynthetic and enzymatic method was developed for the preparation of 13C-labeled verdoheme, which permits the 13C NMR spectroscopic characterization of this elusive intermediate in the heme oxidation path catalyzed by the enzyme heme oxygenase.

Understanding exosomes in regenerative dentistry

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Biochemical properties and bioactivities of carbon monoxide-releasing molecules (CO-RMs).

open access: yes, 2006
Carbon monoxide (CO), synonymous of the "silent killer", is rapidly emerging as an important and versatile mediator of physiological processes. The study of CO has been hampered by the lack of a means to simulate its release biologically.
