Hyperbaric Oxygen Increases Mitochondrial Biogenesis and Function with Oxidative Stress in HL-1 Cardiomyocytes Open
Hyperbaric oxygen (HBO 2 ) therapy has been used to treat various pathological conditions, including carbon monoxide poisoning and ischemia-reperfusion injury. However, the molecular mechanisms underlying these therapeutic effects remain u…

Comparative study of laser-induced spalling behavior on concrete blocks with different water/binder ratios Open
To investigate the effect of the water/binder (W/B) ratio on laser-induced explosive spalling, laser scabbling experiments on concrete blocks were performed. The level of porosity in concrete, which is significantly influenced by the W/B r…

Effect of silica fume content in concrete blocks on laser-induced explosive spalling behavior Open
This experimental study investigated the effect of silica fume mixed in concrete blocks on laser-induced explosion behavior. We used a 5.3 kW fiber laser as a thermal source to induce explosive spalling on a concrete surface blended with a…

Effect of moisture content and mix proportion of concrete on efficiency of laser scabbling Open
Laser scabbling is one of the options that can be used for removal of contaminated concrete when decommissioning and dismantling of nuclear power plant. Laser scabbling can be advantageous for such purpose because laser can transmit throug…

Wavelength-tunable few-cycle pulses in visible region generated through soliton-plasma interactions Open
We numerically investigate the generation of wavelength-tunable few-cycle pulses in the visible spectral region through soliton-plasma interactions. We found that in a He-filled single-ring photonic crystal fiber (SR-PCF), soliton-plasma i…

Spectral tomographic analysis of Bremsstrahlung X-rays generated in a laser-produced plasma Open
A new approach is proposed to analyze Bremsstrahlung X-rays that are emitted from laser-produced plasmas (LPP) and are measured by a stack type spectrometer. This new method is based on a spectral tomographic reconstruction concept with th…

Palmitate induces ER calcium depletion and apoptosis in mouse podocytes subsequent to mitochondrial oxidative stress Open
Pathologic alterations in podocytes lead to failure of an essential component of the glomerular filtration barrier and proteinuria in chronic kidney diseases. Elevated levels of saturated free fatty acid (FFA) are harmful to various tissue…
