For this study, we fabricated transparent Mn-doped tin oxide (MTO)/Ag/MTO films with refractive index-matching layer on a polyethylene terephthalate (PET) substrate. The hybrimer indexmatching layer containing TIP (Titanium isopropoxide) in hydroxy terminated PDMS (PDMS-OH) matrix was placed between the MTO/Ag/MTO multilayer and PET substrate. MTO and Ag were deposited by using RF/DC magnetron sputtering at room temperature, whereas a hybrimer mixture was spin-coated on the PET substrate after adjusting the molar ratios between the TIP and PDMS-OH.

However, pEpiSCs and piPSCs have been technically much harder to culture than mouse embryonic stem cells, showing problematic properties such as spontaneous differentiation and apoptosis after cryopreservation. Therefore, we demonstrated that Y-27632 as a Rho-associated coiled-coil containing kinase inhibitor could prevent dissociated pEpiSCs and piPSCs from undesirable differentiation and apoptosis in cryopreservation protocols.

We assessed the accuracy of an automated, cartridge-based molecular assay for the detection, directly from sputum specimens, of Mycobacterium tuberculosis with resistance to fluoroquinolones, aminoglycosides, and isoniazid.
Methods: We conducted a prospective diagnostic accuracy study to compare the investigational assay against phenotypic drug-susceptibility testing and DNA sequencing among adults in China and South Korea who had symptoms of tuberculosis.
Thiocyanate is present in gold mine tailings waters in concentrations up to 1000mgL and this has a serious environmental impact by not allowing water reuse in the flotation of gold ore. This significantly increases the consumption of fresh water and the amount of wastewater discharged in tailings dams. At the same time thiocyanate in tailings waters often leads to groundwater contamination.

Missionaries built schools and hospitals and effectively used them for evangelism. In the 20th century when Social Gospel Movement was expanding, medical work has been recognized as a significant mission service in and by itself.

Doctors of the past trained under the Japanese colonial system lived and worked as liberalists. More than half of these doctors who were in North Korea defected to South Korea after the country was liberated.

Improving cardiac function may have beneficial effects on cognition; however, no controlled intervention studies have examined this possibility. Cardiac resynchronization therapy (CRT) is one intervention that has been shown to increase cardiac function.
