A slow but steady nanoLuc: R162A mutation results in a decreased, but stable, nanoLuc activity
منشور في 2024"…However, questions related to its mechanism of interaction with the substrate, furimazine, as well as bioluminescence activity remain elusive. Here, we combined molecular dynamics (MD) simulation and mutational analysis to show that the R162A mutation results in a decreased but stable <u>bioluminescence </u>activity of NLuc in living cells and in vitro. …"

Performance evaluation of 3D-printed PLA composites doped with WE43 magnesium alloy for bone tissue engineering applications
منشور في 2025"…While a low Mg content (5 %) only slightly impacted the print quality and dimensions, higher Mg concentrations (10 % and 15 %) led to increased weight, rougher surfaces, dimensional shrinkage in height, and overall poorer formation quality. Adding WE43 alloy to PLA decreased the average pore sizes of the composites. …"

Indomethacin as a Rescue Therapy for Patent Ductus Arteriosus in Extremely Premature Infants after Failed Ibuprofen Treatment
منشور في 2023"…While most PDAs close after one 3-day course of either medicine, a repeat course may be necessary before considering surgical ligation for those who remain with hsPDAs. In our practice, we administer one or two courses of ibuprofen followed by a single course of indomethacin if the PDA has not shown closure or decrease in size on the echocardiogram (echo) exam. …"
