This study examined the effects of the porosity of catalytic bag-filter materials for applications to the SNCR (selective noncatalytic reduction)-SCR (selective catalytic reduction) hybrid process for highly treating nitrogen Oxides (NO) in the exhaust gas of a combustion process. A V₂O/TiO₂ catalyst was dispersed in a PTFE (poly-tetra-fluoro-ethylene) used as the catalytic bag-filter material to remove particulate matter and nitrogen oxides contained in the combustion exhaust gas. Macroporous alumina was added into a V₂O/TiO₂-dispersed PTFE to improve the catalytic activity of V₂O/TiO₂ dispersed in the PTFE material.

They prefer orthokeratology treatment more than wearing spectacles or having a refractive surgery for several reasons. However, there is little research on the effect of orthokeratology treatment on choroids.

Introduction: Massive suprachoroidal hemorrhage (SCH) that completely fills the vitreous cavity rarely resolves spontaneously. Even in cases with spontaneous resolution, long-term visual prognosis is disappointing due to retinal detachment or deterioration of preexisting ocular diseases. To the best of our knowledge, the first case of spontaneous resolution of massive SCH is reported with good long-term visual and anatomic outcome.

We report a case of diabetic papillopathy that demonstrated a resolution of optic disk swelling and rapid visual recovery when intravitreal ranibizumab was administered. A 51-year-old male presented with acute painless visual loss in his right eye. His vision was 20/320 in the right eye and 20/50 in the left eye.

Coronary artery fistulae are usually identified during invasive coronary angiographies. However, in this case, we made the early detection of coronary artery fistulae during non-invasive transthoracic echocardiography, by demonstrating diastolic multiple abnormal color Doppler flows on the entire left ventricular walls including left ventricular free wall, interventricular septum and apex, which were mimicking firecracker on the whole left ventricle. Fistulous communication from the coronary artery to the left ventricle is rare.
