Contraction of heart muscle is triggered by calcium binding to the actin-containing thin filaments but modulated by structural changes in the myosin-containing thick filaments. We used phosphorylation of the myosin regulatory light chain (cRLC) by the cardiac isoform of its specific kinase to elucidate mechanisms of thick filament-mediated contractile regulation in demembranated trabeculae from...

Background and Aim: Several methods have been suggested to measure gingival thick-ness. This study aimed to assess the reliability of visual assessment of facial gingival biotype of maxillary and mandibular teeth with or without using a periodontal probe in comparison with direct measurement. Materials and Methods: Sixty-seven healthy patients (25 women and 42 men) with a total of 100 hopele...

In the fall 2009 issue of Teaching Ethics C.E. Harris wrote an article with a question as the title, “Is Moral Theory Useful in Practical Ethics?” which he answered in the affirmative.1 In Harris’ article he considers two moral theories. “For utilitarianism the purpose of morality is to promote human well-being, and moral principles and judgments should be evaluated in terms of their effectiven...

It was not me who coined the term “ narrative bioethics.” I discovered the term in the title of a dissertation, written by a young theologian, Katrin Bentele, which dealt with ethical dilemmas in doing research on Parkinson (Bentele, 2007). She concluded her dissertation with a quotation out of my book, which has the title, in English, “Deep in the brain” (Dubiel, 2009). This book, in which I d...

Photospheric abundances are presented for 27 elements from carbon to europium in 181 F-G dwarfs from a differential LTE analysis of high-resolution and high signalto-noise spectra. Stellar effective temperatures (Teff) were adopted from an infrared flux method calibration of Strömgren photometry. Stellar surface gravities (g) were calculated from Hipparcos parallaxes and stellar evolutionary tr...

What implications does a dirty-handed politician‟s assertion that dirty hands are necessary for certain political achievements have on our understanding of the relationship between political actors and the political community? The problem of dirty hands, as described in Michael Walzer‟s “Political Action: The Problem of Dirty Hands,” occurs when a political actor finds that he must transgress o...

This 2-article series offers a conceptual, historical, and moral analysis of the practice of triage. Part I distinguishes triage from related concepts, reviews the evolution of triage principles and practices, and describes the settings in which triage is commonly practiced. Part II identifies and examines the moral values and principles underlying the practice of triage.
