Ankle clonus is common after spinal cord injury (SCI) and is attributed to loss of supraspinally mediated inhibition of soleus stretch reflexes and maladaptive reorganization of spinal reflex pathways. The maladaptive reorganization underlying ankle clonus is associated with other abnormalities, such as coactivation and reciprocal facilitation of tibialis anterior (TA) and soleus (SOL), which c...

Recent studies suggest a role for sleep and sleep problems in the etiology of attention deficit hyperactivity disorder (ADHD) and a recent model about the working mechanism of sensori-motor rhythm (SMR) neurofeedback, proposed that this intervention normalizes sleep and thus improves ADHD symptoms such as inattention and hyperactivity/impulsivity. In this study we compared adult ADHD patients (...

We have fabricated high quality sol-gel derived silicate and aluminoborosilicate thin films deposited on silicon substrates. From capacitance vs voltage measurements we observe low interface trap densities (<10H/cm2eV) and very low densities of slow interface state (<101~ 2) in most films investigated. We have been able to make significant improvements over previous sol-gel derived oxides on si...

A microfluidic chip that integrates a sol-gel derived affinity column with a microheater is developed. This microchip includes five electric heaters covered with patterned PMMA for individual heat elution from five sol-gels with target molecules. This study is the first to demonstrate the detection of proteinaptamer interactions on the sol-gel microfluidic system and further describes possible ...

Numerical study of the SOL in the T-11M with the use of a combination of edge and core plasma codes, SOL-DINA and DINA is carried out. Modeling results are compared with experiment for ohmic heating discharges with Li and Carbon limiter in T-11M tokamak. Temperatures, electron density and lithium distribution in SOL are compared. Values for anomalous radial diffusion coefficients of Li ions and...

1. Isometric and isotonic contractile parameters of the soleus (SOL) and medial gastrocnemius (MG) muscles of seven adult cats were studied. In addition, architectural characteristics of six contralateral pairs of these ankle extensors were determined. 2. The in situ peak isometric tetanic tension developed by the MG at the Achilles tendon is nearly 5 times (9,846 vs 2,125 g) that of the SOL mu...

Continuous intramuscular electromyograms (EMGs) were recorded from the soleus (Sol), medial gastrocnemius (MG), tibialis anterior (TA), and vastus lateralis (VL) muscles of Rhesus during normal cage activity throughout 24-h periods and also during treadmill locomotion. Daily levels of MG tendon force and EMG activity were obtained from five monkeys with partial datasets from three other animals...

Highlights 2  Single phase LaTi2Al9O19 (LTA) has been successfully synthesized by sol-gel method at relatively low temperature (1350 o C), something not previously investigated.  The sol-gel synthesized LTA shows good thermochemical stability up to 1500 o C.  Sol-gel synthesized LTA shows higher coefficients of thermal expansion than the solid state reaction synthesized LTA.  LTA is a face ...
