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. …"

The Impact of Learning Computer Programming on the Development of High School Students Cognitive Abilities in the UAE
منشور في 2019"…Twelve cognitive abilities were studied in a mixed-methods research; induction, general sequential reasoning, quantitative reasoning, memory span, working memory, visualization, speed rotation, closure speed, flexibility of closure, visual memory, spatial scanning, and serial perceptual integration. additionally, the researcher had studied students’ choices, perceptions, and classroom practices and linked them to their cognitive style indices. The results revealed that students demonstrated a significant improvement in their induction, quantitative reasoning, closure speed, visual memory, and serial perceptual integration cognitive abilities. furthermore, students demonstrated confidence and positive attitude toward learning programming. however, students’ awareness of the usefulness of learning programming and their motivation to learn it was not evident. there was no significant impact of gender on students’ choices of studying programming. on another hand, students’ cognitive style index who chose to study programming was more analytic than intuitive. yet, male students were more analytic than females. …"

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. …"

Revisiting high-density lipoprotein cholesterol in cardiovascular disease: Is too much of a good thing always a good thing?
منشور في 2024"…Despite the correlation between low high-density lipoprotein cholesterol (HDLC) and heightened CVD risk, HDL-raising therapies have yet to showcase significant clinical benefits. Furthermore, evidence from epidemiological and genetic studies reveals that not only low HDL-C levels, but also very high levels of HDL-C are linked to increased risk of CVD. …"
