OBJECTIVE Beta-blocking therapy is the standard therapy in non-operated Marfan patients, however its efficacy after entire aortic replacement is unknown. The aim of this study was to describe the influence of (nearly) entire aortic replacement and beta-blocking therapy on blood pressure and wave reflections in Marfan patients. METHODS Four Marfan patients (mean age 31+/-3 years) and 8 age mat...

Acinar cell tumors of the pancreas are uncommon and they include acinar cell carcinomas, acinar cell cystadenocarcinomas and acinar cell cystadenomas (ACCs) (1-5). These tumors are composed of typical round or cylindrical cells with eosinophilic periodic acid stain (PAS)positive cytoplasmic granules. On immunohistochemical analysis, they express pancreatic enzymes, and electron microscopy demon...

JEL classification E52 This paper examines the credibility of the Federal Reserve's monetary targets using survey data on money growth forecasts to measure market expectations. The paper provides two main results. First, there is strong evidence that the monetary targets were credible over the 1978 to 1993 sample period, although credibility fell in the post-1985 period. Second, both the federa...

Parkinson disease (PD) is a neurodegenerative disease primarily characterized by cardinal motor manifestations and CNS pathology. Current drug therapies can often stabilize these cardinal motor symptoms, and attention has shifted to the other motor and nonmotor symptoms of PD that are resistant to drug therapy. Dysphagia in PD is perhaps the most important drug-resistant symptom because it lead...

BACKGROUND Little information is available on the joint effects of multiple impairments (coimpairments) on the risk of disability. Our aim was to study the joint effects of strength and balance impairments on severe walking disability. METHODS The data are from the baseline of the Women's Health and Aging Study (WHAS), a study of moderately to severely disabled women. A total of 1,002 women a...

To achieve higher economy of the original driving scheme with single motor and settled gear ratio, new configurations with different powertrain systems in front and rear axle were designed. Firstly, according to the power and torque required by a micro electric vehicle (mEV) in various drive cycles, the parameters of a small and high power motor were determined. Secondly, for schemeⅠwith dual m...

The neural network algorithm in this paper is applied to the ocean surface wind speed retrievals. Firstly, the Ku band backscattering coefficient (σKu) is considered as the input parameter to retrieve the wind speed and the retrieval precision reaches 1 m/s (root mean square error) for HY2 altimeter. Secondly, by introducing the Ku-band significant wave height (swhku), C-band backscattering coe...

Fuzzy clustering algorithm can not obtain good clustering effect when the sample characteristic is not obvious and need to determine the number of clusters firstly. For thi0s reason, this paper proposes an adaptive fuzzy kernel clustering algorithm. The algorithm firstly use the adaptive function of clustering number to calculate the optimal clustering number, then the samples of input space is...
