Interpreting Photoactive Fluorescence Microscopy Measurements of Steady-State Actin Dynamics
Biophysical Journal, 1995A continuum model describing the steady-state actin dynamics of the cytoskeleton of living cells Has been
developed to aid in the interpretation of photoactivated fluorescence experiments. In a simplified cell geometry, the model
assumes uniform concentrations of cytosolic and cytoskeletal actin throughout the cell and no net growth of either pool. The
spatiotemporal evolution of the fluorescent actin population is described by a system of two coupled linear partial-differential
equations. An analytical solution is found using a Fourier-Laplace transform and important limiting cases relevant to the
design of experiments are discussed. The results demonstrate that, despite being a complex function of the parameters, the
fluorescence decay in photoactivated fluorescence experiments has a biphasic behavior featuring a short-term decay
controlled by monomer diffusion and a long-term decay governed by the monomer exchange rate between the polymerized
and unpolymerized actin pools. This biphasic behavior suggests a convenient mechanism for extracting the parameters
governing the fluorescence decay from data records. These parameters include the actin monomer diffusion coefficient,
filament turnover rate, and ratio of polymerized to unpolymerized actin

MOTOR UNIT FIRINGS DURING VOLUNTARY ISOMETRIC RAMP AND BALLISTIC CONTRACTIONS IN HUMAN VASTUS MEDIALIS MUSCLE
Intra-muscular electromyographic (EMG) signals in vastus medialis muscle were decomposed into their constituent motor unit action potential trains using a specially designed quadrifilar wire electrode during voluntary isometric ramp and ballistic contractions. Five male adults participated in our experiments as subjects and performed ramp trapezoidal, ramp triangular, and ballistic contractions. By using a newly developed wire electrode, intra-muscular EMG signals were successfully decomposed into the individual motor unit action potential trains. The firing behaviors analyzed by the decomposition technique were consistent with previous studies on small muscles. This new quadrifilar wire electrode is potentially a useful tool for detecting intra-muscular electromyographic signals in large limb muscles such as the vastus medialis

Anatomy Of The Upper Airway And Its Growth In Childhood
Because several craniofacial anomalies are related to the narrow upper airway, for example narrow maxilla or retruded mandible, orthodontists and oral and maxillofacial surgeons are involving diagnosis and treatment of paediatric obstructive sleep apnoea. The knowledge of anatomy of the upper airway and its growth change in childhood is crucial for both clinical and research purposes.published_or_final_versio
