The effects on the redox properties of modifying the molecular skeleton of neutral bis-2-(4-dimethylamino)pyridinylidene electron donors, derived from 4-dimethylaminopyridine (4-DMAP), have been explored, by varying two parameters: (i) the length of a polymethylene chain linking the two pyridine-derived rings and (ii) the nature of the nitrogen substituents on the 4 and 4' positions of the prec...
A proper alignment of the ultrasound beam to the aortic or pulmonary outflow tracts is essential to acquire accurate signals. This study aimed to investigate the influence of different positions on the acquisition of Doppler signals using a noninvasive transcutaneous Doppler ultrasound. This was a prospective observational crossover study. Two operators performed hemodynamics measurements on ea...
An all-against-all protein structure comparison using the Combinatorial Extension (CE) algorithm applied to a representative set of PDB structures revealed a gallery of common substructures in proteins (http://cl.sdsc.edu/ce.html). These substructures represent commonly identified folds, domains, or components thereof. Most of the subsequences forming these similar substructures have no signifi...
ABSTRACT This article analyzes how niche parties may utilize a strategy of policy shifting to garner additional voters. It leverages unique opportunity in which Costa Rican political party released two different versions its manifesto at moments during single election cycle. rare uncovers the shifted from having hard conservative stance on social issues, such as abortion, moderating and centeri...
purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...
This study aims at evaluating spinal alignment during sleep by combining personalized human models with mattress indentation measurements. A generic surface model has been developed that can be personalized based on anthropometric parameters derived from silhouette extraction. Shape assessment of the personalized surface models, performed by comparison with 3-D surface scans of the trunk, showe...
