Background:  There is no consensus on the best surgical treatment in Kienböck disease. We compared the shortterm outcomes of radial shortening osteotomy and capitate shortening osteotomy in patients affected with this disease.  Methods:  In a retrospective study of 21 patients with Lichtman stage IIIA of Kienböck disease, 12 patients with an average follow up of 3.2 ± 0.6 years had radial short...

background: limited resources for adult stem cells necessitate their in vitro culture prior to clinical use. investigating mitochondrial dna (mtdna) and telomere shortening has proved to be important indications of stem cell validity. this study was designed to investigate these indicators in multiple passages of three adult stem cell lines which were produced in our stem cell laboratory. metho...

The aim of this study was to investigate the relationship between compensatory shortening and coarticulation in German tense and lax vowels in trochees and iambs and to determine whether this relationship was influenced by prosodic accentuation. Speakers produced near minimal pairs differing in vowel tensity in monosyllabic and disyllabic words (both trochees and iambs) in accented and deaccent...

This study investigates whether the stress foot is a planned timing unit in American English, by examining the durational characteristics of the foot in three different prosodic contexts i) within an intermediate phrase, ii) across an intermediate phrase and iii) across an intonational phrase. The results show that as the number of syllables in a foot increases, the duration of the foot increas...

Background Cardiovascular magnetic resonance (CMR) is the gold standard to measure right ventricular ejection fraction (RVEF). Longitudinal shortening is historically known to be the predominant part of its global systolic function and less attention has been paid to the transversal contraction. The aim of this study was to evaluate RV transverse motion in a large cohort of patients referred fo...

KEY POINTS This paper describes a novel model that allows exploration of matrix-induced cardiomyocyte adaptations independent of the passive effect of matrix rigidity on cardiomyocyte function. Detachment of adult cardiomyocytes from the matrix enables the study of matrix effects on cell shortening, Ca2+ handling and myofilament function. Cell shortening and Ca2+ handling are altered in cardiom...

Impaired shortening deactivation of cardiac myocytes could sustain myocardial contraction, preserving ejection fraction at the expense of diastolic dysfunction. We examined the relationship between first-phase ejection fraction (EF1), the fraction of left ventricular volume ejected from the start of systole to the time of the first peak in left ventricular pressure (corresponding to the time of...

The effect of coronary artery bypass grafts on left ventricular performance was evaluated by analyzing preoperative (preop) and postoperative (postop) biplane left ventriculograms of 37 patients who were restudied at a mean of 13 months after operation. Eighty-two percent of the grafts were patent. Segmental wall shortening and segmental shortening velocities (mea Vcf) in the anterior, inferior...
