BACKGROUND Advanced age is associated with left ventricular (LV) remodeling and impaired diastole. The association among aging, mitral leaflet closure (EF slope), cardiac structures, and diastolic indices in an asymptomatic Taiwanese population is largely unknown. METHODS We studied 8103 asymptomatic participants (49.5 ± 11.6 years, 38.2% women) from a health evaluation cohort (2004-2012) in ...

conclusions gated spect mpi has a good correlation with echocardiography for the measurement of left ventricular ef, edv, and esv in patients with severe heart failure. however, the absolute values of these functional parameters from echocardiography and gated spect mpi measured with different software packages should not be used interchangeably. results a good correlation was found between ech...

We measured right and left ventricular ejection fracttion (EF) from high frequency time-activity curves obtained during the initial passage of an intravenous bolus of 99mTc (Sn) pyrophosphate. In 22 normal controls right ventricular EF averaged 0.52 +/- 0.04 (SD). In 24 acute anterior or lateral infarction patients right ventricular EF was normal (0.56 +/- 0.10), while left ventricular EF was r...

In this paper we study the implications of the recent high precision measurement of (g−2)μ by BNL [1] on new heavy physics beyond the SM. The effect of two d=6 operators on the anomalous magnetic momment of the muon is considered and the new physics contribution to aμ reported by BNL has been used to put bounds on the scale associated with these operators.

Applied behavior analysis (ABA) is a science and, therefore, involves progressive approaches and outcomes. In this commentary we argue that the spirit and the method of science should be maintained in order to avoid reductionist procedures, stifled innovation, and rote, unresponsive protocols that become increasingly removed from meaningful progress for individuals diagnosed with autism spectru...

salivary gland involvement is one of the radioiodine therapy complications. salivary gland scintigraphy in quantitative mode can accurately evaluate salivary gland function. methods: salivary gland scintigraphy was performed with tc-99m pertechnetate, at the time of iodine therapy as a basic study and then 3 weeks and 3 months afterwards. ejection fraction (ef) of parotid and submandibular glan...

Decline in executive functioning (EF) is a hallmark of cognitive aging. We have previously reported that faster vagal recovery from cognitive challenge is associated with better EF. This study examined the association between vagal recovery from cognitive challenge and age-related differences in EF among 817 participants in the Midlife in the U.S. study (aged 35-86). Cardiac vagal control was m...
