Reference jitter values for concentric needle electrodes in voluntarily activated extensor digitorum communis and orbicularis oculi muscles.

The aim of this study was to estimate normal jitter in voluntarily activated extensor digitorum communis (EDC) and orbicularis oculi (OOc) muscles using a disposable concentric needle electrode (CNE). The EDC of 67 normal subjects (22 males and 45 females, mean age 35.5 +/- 10.2 years) and the OOc of 50 normal subjects (13 males and 37 females, mean age 37.9 +/- 9.6 years) were studied. Jitter ...

Quantification of microspheres appearance in brain vessels: implications for residual flow velocity measurements, dose calculations, and potential drug delivery.

BACKGROUND AND PURPOSE Characteristics of ultrasound-activated gaseous microspheres (muS) reflective of their size and quantities are needed for future dose-escalation and drug delivery trials. METHODS A double-blind, interobserver-validated analysis of multi-gate power-motion Doppler microS traces included large (>8 micro) microS from agitated saline injections in the right-to-left shunt (RL...

Antibody reactive with Peptostreptococcus micros in the sera of patients with periodontal disease.

Subgingival plaque samples were cultured for the isolation of Peptostreptococcus micros from individuals with and without chronic periodontitis. Humoral antibody from each person reacted with P. micros in an indirect fluorescent-antibody test, but not all of the sera reacted in a passive hemolysis test. No correlations were observed between the presence of antibody reactive with P. micros and t...

Strong effects of molecular topology on diffusion of entangled DNA molecules.

When long polymers such as DNA are in a highly concentrated state they may become entangled, leading to restricted self-diffusion. Here, we investigate the effect of molecular topology on diffusion in concentrated DNA solutions and find surprisingly large effects, even with molecules of modest length and concentration. We measured the diffusion coefficients of linear and relaxed circular molecu...
