2H-NMR as a Practical Tool for Following MOF Formation: A Case Study of UiO-66.

Developing the mechanism for MOF formation is crucial for the rapid development of new materials. This work demonstrates that Deuterium-NMR spectroscopy is the optimal inter-laboratory methodology for understanding the in-situ kinetics of metal-organic framework (MOF) formation. This method is facile, affordable, and allows for the isolation and monitoring of individual reagents by using one deuterated component while the remaining components are protonated.

Department of Management and Marketing, Notre Dame University Louaize, Zouk Mosbeh, Lebanon.
Purpose: This study aims to examine the relationships between organizational culture, employee loyalty, trust and job satisfaction within the Lebanese health-care sector. It addresses the critical need to improve employee retention and organizational performance in a context marked by economic instability and political uncertainty. By analyzing data from 270 health-care professionals, the study aims to explore how different aspects of organizational culture - such as transparency, supportiveness and ethical leadership - affect employee trust and satisfaction.

Asymmetric cell division (ACD) allows daughter cells of a polarized mother to acquire different developmental fates. In , the Wnt/β-catenin Asymmetry (WβA) pathway regulates many embryonic and larval ACDs; here, a Wnt gradient induces an asymmetric distribution of Wnt signaling components within the dividing mother cell. One terminal nuclear effector of the WβA pathway is the transcriptional activator SYS-1/β-catenin.

β-tubulin isotypes exhibit similar sequences but different activities, suggesting that limited sequence divergence is functionally important. We investigated this hypothesis for TUBB3/β3, a β-tubulin linked to aggressive cancers and chemoresistance in humans. We created mutant yeast strains with β-tubulin alleles that mimic variant residues in β3 and find that residues at the lateral interface are sufficient to alter microtubule dynamics and response to microtubule targeting agents.

Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN.
Purpose: To advance our understanding of disease-specific articulatory impairment patterns in speakers with dysarthria, this study investigated the articulatory performance of the tongue and jaw in speakers with differing neurological diseases (Parkinson's disease [PD], amyotrophic lateral sclerosis, multiple sclerosis, and Huntington's disease).
Method: Fifty-seven speakers with dysarthria and 30 controls produced the sentence "Buy Kaia a kite" five times. A three-dimensional electromagnetic articulography was used to record the articulatory movements of the posterior tongue and jaw.
