This paper illustrates the design of a nonlinear filter for edge-enhancing smoothing of multiplicative noise using a morphology-based filter structure. This filter is called the Minimum Coefficient of Variation (MCV) filter. The coefficient of variation is the ratio of the standard deviation of a random process to its mean. For an image corrupted only by stationary multiplicative noise, the coe...

BACKGROUND AND PURPOSE There are several reports that have studied the effects of hyperbaric oxygen (HBO) on cerebral blood flow (CBF). However, most of the reports have been of animal experiments, and human studies are few so far. The aim of this study is to clarify the relationship between HBO and CBF in humans. METHODS Middle cerebral arterial blood flow velocity (MCV) was measured using t...

Viral latency, in which a virus genome does not replicate independently of the host cell genome and produces no infectious particles, is required for long-term virus persistence. There is no known latency mechanism for chronic small DNA virus infections. Merkel cell polyomavirus (MCV) causes an aggressive skin cancer after prolonged infection and requires an active large T (LT) phosphoprotein h...

In addition to the previously characterized viruses BK and JC, three new human polyomaviruses (Pys) have been recently identified: KIV, WUV, and Merkel Cell Py (MCV). Using an ELISA employing recombinant VP1 capsid proteins, we have determined the seroprevalence of KIV, WUV, and MCV, along with BKV and JCV, and the monkey viruses SV40 and LPV. Soluble VP1 proteins were used to assess crossreact...

BACKGROUND Transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve (MCV) system might represent an alternative to conventional redo surgery in older high-risk patients with a failing aortic valve bioprosthesis. METHODS AND RESULTS Symptomatic patients with failing aortic valve bioprosthesis, aged ≥65 years with a logistic EuroSCORE ≥10 % were considered for treatment. Loc...

The present study was designed to establish the role of Gamma-glutamyl transpeptidase (gamma-GT) and mean corpuscular volume (MCV) in alcoholic liver disease (ALD). Serum gamma-GT, total and direct bilirubin, albumin, total protein, AST, ALT and ALP were assayed by standard methods in a clinical chemistry autoanalyser. MCV, Hb, PCV and RBC were measured by an automated cell counter. Activity of...

ued. During 2006–2014, the incidence of meningococcal disease caused by vaccine-covered serogroups among US military recipients of MCV-4 fell to 0.146 per 100,000 person-years, whereas MPVS-4–related incidence did not change (M.P. Broderick, pers. comm.). Furthermore, through July 2016, the US military has not seen a case from a covered serogroup since 2011 among recipients of MCV-4. Even with ...

The mean corpuscular volume (MCV) of blood after storage for up to 24 days under various temperature conditions in ethylene diamine tetracetic acid, acid citrate dextrose, citrate phosphate dextrose, and Alsever's solution was measured using the Coulter S. Storage of blood overnight at 23 degrees centigrade increased the MCV, while there was no significant change after similar storage at 4 degr...
