OBJECTIVE The purpose of this study was to examine the immediate effects of spinal manipulative therapy (SMT) on trunk proprioception in subjects with asymptomatic chronic low back pain (CLBP) and determine if those effects lasted 1 week. METHODS This unbalanced randomized controlled crossover design examined 33 subjects with CLBP. Proprioception was(More)
Cardiotonic glycosides are extracted mostly from leaves of Digitalis plants. Commercial production of bioactive secondary metabolites by traditional agriculture is an inefficient process and can be affected by climatic and soil conditions. Strategies, based on in vitro culture methods, have been extensively studied to improve the production of specific(More)
A new procedure has been developed for the in situ FT-IR determination of rosmarinic acid (RA) in suspension cultures of Lavandula officinalis. The method involves sample preparation on ZnSe crystals or microplates from silicon, and measuring absorbance spectra between 4000 and 700 cm(-1). First derivative spectra were analysed after normalisation using(More)
Submerged fermentation in a stirred bioreactor of the white rot fungus Cerrena unicolor C-139 was done at a 120-L scale in the presence of wheat bran as a cheap lignocellulosic substrate for fungus growth and laccase production. Enzyme monitoring showed that laccase production started after 2 days of cultivation, attaining a maximum activity of 416.4(More)
We show that a finite Markov exchangeable sequence of random variables with finite state space is a signed mixture of Markov chains. This is shown to partially generalize earlier work by Fortini et al. and Freedman under the added condition of stationarity. Associated statistical issues are discussed and a test of Markov exchangeability is proposed.
In the partially catabolically-derepressed mutant ofTrichoderma viride grown on lactose the excretion of cellulase into the medium started when the concentration of sugar in the medium decreased below 0.4 % and was preceded by a rapid transient increase of total ATP concentration in the culture. After reaching the maximum, the ATP level started to decrease(More)

The need for outcome assessment in stroke management is a critical part of specialized stroke unit development. The Comprehensive Assessment Toolbox for Stroke was developed for this reason. This study describes the implementation of the Toolbox across a medical system as part of a stroke center of excellence. Toolbox data were collected from 2002 to 2004.(More)
Calibration is a technique that is commonly used in science and engineering research that requires calibrating measurement tools for obtaining more accurate measurements. It is an important technique in various industries. In many situations, calibration is an application of linear regression, and is a good topic to be included when explaining and learning(More)
