BACKGROUND This study was proposed to evaluate a new method for autograft transplantation of liver tissue fragments (LTF) in the lung parenchyma and bronchus of dogs and to compare the results to find out if they are suitable sites for hepatocyte implantation or not. MATERIALS AND METHODS THE DOGS WERE RANDOMLY ASSIGNED INTO TWO CATEGORIES: LTF auto-transplantation to the lung parenchyma and ...

Glutamatergic synapses are highly modifiable, suiting them for key roles in processes such as learning and memory. At crayfish glutamatergic neuromuscular junctions, hyperpolarization and cyclic nucleotide-activated (HCN) ion channels mediate hormonal modulation of glutamatergic synapses and a form activity-dependent long-term facilitation (LTF) of synaptic transmission. Here, we show that a ne...

Low molecular weight thymic factor stimulates the suppressor function of T-lymphocytes, increases cAMP content (but not cGMP) in lymphocytes and inhibits histamine release from sensitized basophils. The mechanisms of LTF action are discussed.

In addition to a reduced number of feeders, which would simplify their integration in the cryostat tokamak, present study considers possibility reduce voltage during safety discharge toroidal field (TF) coils. A lowered ease manufacture TF coils and operational risks. Both aspects closely related time constant, determined by ratio LTF/Rd, where Rd is resistance dump resistor LTF inductance coil...

A new improved soft-feedback functional link artificial neural-network (ISFFLANN) based nonlinear channel equalizer is proposed in this paper. By using the functional expansion utilities, the ISF-FLANN does not need the hidden layers, which are existed in most of the multilayer perceptron network (MLP)-based equalizers. So the ISF-FLANN exhibits much simpler structure and thus requires less amo...

The contributions of the amygdaloid central nucleus (ACe) to the modulation of the amplitude of the nictitating membrane reflex (NMR) were determined. Experiment 1 demonstrated that low-level electrical stimulation of the ACe enhances the amplitude of the NMR when administered immediately preceding the elicitation of the reflex by an eyelid stimulus. In Experiment 2 the anterograde transport of...

Background Long-term forgetting (LTF) over days or weeks may be a sensitive early marker of Alzheimer’s disease (AD), useful for preclinical AD trials. We examined associations between LTF and markers brain pathology in individuals from the world’s largest kindred with autosomal dominant due to Presenilin-1 (PSEN1) E280A mutation. Methods A total 14 cognitively unimpaired PSEN1 mutation carrier...

Presynaptic I(h) channels become activated during a tetanus through membrane hyperpolarization resulting from Na(+) accumulation and electrogenic Na(+)/K(+) exchange. I(h) activation is obligatory for inducing long-term facilitation (LTF), a long-lasting synaptic strengthening. cAMP-induced synaptic enhancement also requires I(h) activation, and both processes are sensitive to actin depolymeriz...

Abstract In mainland China, approximately 86% of M≥7 earthquakes have occurred in the block boundary zone, which has been well explained by active theory. However, a few large within block, provides us with an opportunity to better study deformation Tibetan Plateau. The Litang Fault (LTF) is strike-slip fault Sichuan-Yunnan Active Block and produced 1948 M7.3 earthquake. We presented Holocene r...
