right-sided heart thrombus is a life-threatening condition that necessitates immediate therapy. detection of right-sided heart thrombus is usually via transthoracic echocardiography. generally, thrombolysis is considered a treatment of choice, but there is currently no consensus about the optimal therapeutic choice. we present a case of multiple right atrial thrombi with concurrent mobile and b...

Vibration characteristics of a self-oscillating two-layer vocal fold model with left-right asymmetry in body-layer stiffness were experimentally and numerically investigated. Two regimes of distinct vibratory pattern were identified as a function of left-right stiffness mismatch. In the first regime with extremely large left-right stiffness mismatch, phonation onset resulted from an eigenmode s...

Scaly-sided Merganser is a globally endangered species restricted to eastern Asia. Estimating its population is difficult and considerable gap exists between populations at its breeding grounds and wintering sites. In this study, we built a species distribution model (SDM) using Maxent with presence-only data to predict the potential wintering habitat for Scaly-sided Merganser in China. Area un...

By means of an analysis on evanescent waves in left-handed materials (LHM), we show that within a slab of such a medium, sandwiched between two positive refraction media, there is amplification of evanescent waves in ideal lossless, dispersiveless media; however, contrary to previous claims, this is limited to a finite width of the slab so that it prevents their restoration and perfect focusing...

background and objective: sleep-disordered breathing (sdb) is associated with increased morbidity and mortality in patients with heart failure (hf). we assessed the prevalence and the pattern of sdb in hf patients who were candidates for heart transplantation. materials and methods: twenty heart transplantation patients with ventricular ejection-fraction < 25% were recruited consecutively in a ...

Shortage of donors enhances harvesting of borderline hearts. When such organs fail, a ventricular assist device may salvage the patient waiting for either recovery or for retransplantation. We describe a series of 12 patients who required circulatory support following orthotopic heart transplantation, with the use of four different devices. Four patients survived. The aim of this study is to de...

We constructed a prototype of an electrolarynx whereof the fundamental frequency (hereafter pitch for simplicity) can be adjusted by an up-down or left-right finger movement, and carried out some comparison experiments on its operation. As a result, we found that the left-right finger movement could operate the device more simply and in a shorter time. In both cases, in the prototype electrolar...

Although the number of available donor hearts severely limits the epidemiologic impact of heart transplantation on patients with heart failure, patients with end-stage heart failure unresponsive to medical management currently have no other viable alternatives. Destination therapy with a ventricular assist device is the closest toward approaching clinical reality but has been plagued with probl...

Amyloidosis is a rare disorder characterized by the deposition of amorphous, extracellular, insoluble fibrillar protein in various tissues of the body. Pulmonary hypertension usually occurs in the last stages of the disease with co-existing left ventricular failure. Amyloidosis causing pulmonary hypertension in a patient with no evidence of left ventricular failure is rarely mentioned in litera...
