Patients with symptoms of cerebral ischemia are often evaluated with non-invasive carotid artery testing. An abnormal carotid Doppler ultrasound frequency shift pattern of early systolic flutter (ESF) was demonstrated by auscultation and velocity wave form analysis in patients with normal carotid bifurcations. Ten of these patients were studied with echocardiography (echo) and eight had mitral ...

The motion vector prediction (MVP) is an important part of video coding. In the original median predictor, if the neighbor blocks of current block are intramode coded, their motion vectors (MVs) will be set to zeros for MVP of current block. This is not very precise for sequences with strong motion. This paper propose an improved motion vector prediction (MVP) scheme for H.264. In the proposed ...

OBJECTIVES To better establish the clinical features, natural history, clinical management, and rehabilitation implications of dysautonomia after traumatic brain injury, and to highlight difficulties with previous nomenclature. METHODS Retrospective file review on 35 patients with dysautonomia and 35 sex and Glasgow coma scale score matched controls. Groups were compared on injury details, CT...

The study by Wilcken and Hickey' in Circulation and the accompanying editorial comment by Devereux2 indicated that mitral valve prolapse (MVP) leads to severe mitral regurgitation (MR) much more frequently in men than in women. Both studies seemed to attribute the sex difference to higher blood pressure in men than women, as suggested by Roberts.3 However, Roberts' conclusion that the number of...

OBJECTIVE This study explored the prevalence of panic disorder and other psychiatric disorders in young Han Chinese males with mitral valve prolapse (MVP). With the factors of age, sex, and ethnicity controlled, the specific role of MVP in panic disorder was analyzed. METHODS Subjects with chest pain aged between 18 and 25 years were assessed with the echocardiograph for MVP and the Chinese v...

Vaults are evolutionary highly conserved ribonucleoproteins particles with a hollow barrel-like structure. The main component of vaults represents the 110 kDa major vault protein (MVP), whereas two minor vaults proteins comprise the 193 kDa vault poly(ADP-ribose) polymerase (vPARP) and the 240 kDa telomerase-associated protein-1 (TEP-1). Additionally, at least one small and untranslated RNA is ...

BACKGROUND The outcome of mitral valve prolapse (MVP) is controversial, with marked discrepancies in reported complication rates. METHODS AND RESULTS We conducted a community study of all Olmsted County, Minn, residents first diagnosed with asymptomatic MVP between 1989 and 1998 (N=833). Diagnosis, motivated by auscultatory findings (n=557) or incidental (n=276), was always confirmed by echoc...

Mitral valve prolapse (MVP) is the most common valve anomaly and the most frequent cause of isolated mitral insuffi ciency. MVP has a mostly benign course and prognosis in childhood; however, complications, such as severe mitral regurgitation, infectious endocarditis, pulmonary embolism, arrhythmia and sudden death, occur more often in elderly people, demonstrating the need for prompt diagnosti...

BACKGROUND Mitral valve repair is preferred over prosthetic replacement. We surgically repaired mitral valve with degenerated sclerotic lesion and demonstrated mid-term results. METHODS Mitral valve plasty (MVP) was performed with several procedures including ring annuloplasty, leaflet slicing and decalcification. RESULTS There were 19 males and 19 females with a mean age of 67 ± 12 y.o (n ...
