reelin is an extracellular matrix neuroprotein which plays important roles during development and maturation of cerebellum. in the postnatal cerebellum, reelin is synthesized by cerebellar granule cells and secreted to extracellular matrix. this secreted protein modulates adult synaptic function, neurotransmitter release and regulates plasticity. exercise has beneficial effects on central nervo...

Sieck, Gary C., and Michael Regnier. Invited Review: Plasticity and energetic demands of contraction in skeletal and cardiac muscle. J Appl Physiol 90: 1158–1164, 2001.—Numerous studies have explored the energetic properties of skeletal and cardiac muscle fibers. In this mini-review, we specifically explore the interactions between actin and myosin during cross-bridge cycling and provide a conc...

The cardiac extracellular matrix (ECM) is a complex architectural network consisting of structural and nonstructural proteins, creating strength and plasticity. The nonstructural compartment of the ECM houses a variety of proteins, which are vital for ECM plasticity, and can be divided into 3 major groups: glycoproteins, proteoglycans, and glycosaminoglycans. The common denominator for these gr...

The effects of classical conditioning on frequency receptive fields (RFs) in the ventral, tonotopic part of the guinea pig (Cavia porcellus) medial geniculate ventral body (MGv) during cardiac conditioning to a single tone frequency were studied. Associative frequency-specific plasticity, in which the RF was returned to the frequency of the conditioned stimulus (CS), developed if the CS frequen...

t-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. this usually happens when the monitoring lead displays a tall t wave, which is also sharp. r wave sensing algorithms of the devices do not sense t wave because the slow rate of the t wave is much less than that of the r wave. but the slow rate of t waves may change with time and also beca...

One of the new research fields in plasticity is related to choosing a proper non-associated flow rule (NAFR), instead of the associated one (AFR), to predict the experimental results more accurately. The idea of the current research is derived from combining von Mises and Tresca criteria in the places of yield and plastic potential surfaces in rate-independent plasticity.  This idea is implemen...
