BACKGROUND AND PURPOSE Transfusion-transmitted virus (TTV), a recently discovered DNA virus, was first identified in patients with non-A to -G hepatitis following blood transfusion. Transmission is generally via the parenteral route but recent data suggest that TTV can also be transmitted by the fecal-oral route. METHODS This cross-sectional study was conducted in March 2005 and included 324 ...

background and aims: recently, a novel dna virus was isolated from the serum of a patient with post-transfusion non a-g hepatitis and named tt virus. the aim of this study was to determine the prevalence tt virus among cirrhotic patients due to hepatitis b & c in infection ahwaz. methods: the prevalence of ttv infection was studied in 41 patients with liver cirrhosis. ttv dna was detected by se...

In late 2005, a postweaning, high mortality syndrome spread rapidly through finishing barns in swine dense areas of the United States. Diagnostic investigations consistently detected porcine circovirus type 2 (PCV2) from diseased tissues. Subsequent genetic analysis revealed that the infectious agent was a PCV2 type termed "PCV2b". Prior to late 2004, only the PCV2a type, but not PCV2b, had bee...

A new type of fluorescent sensor has been developed from a perylene based molecule, N,N0-dideoxythymidine-3,4,9,10-perylene-tetracarboxylic diimide (TT-PTCDI); the strong, highly selective binding between the thymine ligand (T) and Hg ion enables efficient sensing of mercury ions based on a fluorescence quenching mechanism, which is primarily caused by metalcoordination induced molecular aggreg...

We investigated lower-extremity isometric tremor Approximate Entropy (irregularity), torque steadiness and rate of force development (RFD) and their associations to muscle activation strategy during isometric knee extensions in patients with Parkinson's disease (PD). Thirteen male patients with idiopathic PD and 15 neurologically healthy matched controls performed isometric maximal contractions...

Infection with Torque teno viruses (TTVs) is not restricted to humans. Different domestic and wild animal species are naturally infected with species-specific TTVs worldwide. Due to the global spread of the infection, it is likely that essentially all animals are naturally infected with species-specific TTVs, and that co-evolution of TTVs with their hosts probably occurred. Although TTVs are po...
