Quantitative measures of postural tremor at the upper limb joints in patients with essential tremor.

Background: It is important to quantitatively assess tremor for accurate diagnosis and evaluation of the response to interventions in patients with essential tremor (ET).

Objective: The purpose of this study was to investigate the relationship between quantitative measures of postural tremor and clinical rating scale in patients with ET.

Methods: 18 ET patients performed a postural tremor task that required them to hold their arms outstretched parallel to the floor while wearing a gyro sensor based measurement system.

Purification, characterization and molecular cloning of Vibrio fluvialis hemolysin.

Hemolysin of Vibrio fluvialis (VFH) was purified from culture supernatants by ammonium sulfate precipitation and successive column chromatographies on DEAE-cellulose and Mono-Q. N-terminal amino acid sequences of the purified VFH were determined. The purified protein exhibited hemolytic activity on many mammalian erythrocytes with rabbit erythrocytes being the most sensitive to VFH.

Characterization of Vibrio mimicus phospholipase A (PhlA) and cytotoxicity on fish cell.

Vibrio mimicus is a typical strain of Vibrio cholerae and produces a phospholipase (PhlA) which shares a highly conserved amino acid sequence with the lecithinase (Lec) of V. cholerae. The recombinant protein (rPhlA) produced from the phlA gene of V.
