OBJECTIVE To assess the cost-effectiveness and cost-utility of Spinal Cord Stimulation (SCS) in patients with failed back surgery syndrome (FBSS) refractory to conventional medical management (CMM). MATERIALS AND METHODS We conducted an observational, multicenter, longitudinal ambispective study, where patients with predominant leg pain refractory to CMM expecting to receive SCS+CMM were recr...

INTRODUCTION Transplantation of bone marrow stromal cells (BMSCs) or Schwann cells (SCs) can increase axonal regeneration in peripheral nerve injuries. Based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury. We pursued to evaluate the effects of BMSCs and SCs co-transplantat...

Most of the isolates of Bordetella bronchiseptica obtained by this laboratory possessed a characteristic colonial morphology when grown on Bordet- Gengou agar (BGA) at 37 degrees C. The colonies appeared domed (Dom+) with a smooth colonial surface (Scs+) and a clear zone of hemolysis ( Hly +). From these Dom+ Scs+ Hly + BGA colony types arose flat (Dom-), smooth colonial surface (Scs+) and nonh...

Without Focal Adhesion Kinase (FAK), developing murine Schwann cells (SCs) proliferate poorly, sort axons inefficiently, and cannot myelinate peripheral nerves. Here we show that FAK is required for the development of SCs when their basal lamina (BL) is fragmentary, but not when it is mature in vivo. Mutant SCs fail to spread on fragmentary BL during development in vivo, and this is phenocopied...

Rapid development of tissue engineering techniques has led to the possibility of treating central nervous injuries with Schwann cells (SCs). However, certain characteristics of SCs, such as a low proliferation ability, greatly restrict their use. The aim of the present study was to investigate whether SCs differentiated from adipose‑derived stem cells (ADSC‑SCs) could used to promote functional...

-The trustworthiness of safety critical system (SCS) is very important. To assess their trustworthiness depends on data from test. In order to ensure the reliability and validity of test data, especially for such complex SCS, development of test languages is inevitable trend for automatic test of SCS. As general test language for SCS should be independent of specific equipment, in the paper typ...

S U M M A R Y We infer shear attenuation in the lower mantle by using the method of instantaneous frequency matching to calculate differential t∗ between core-reflected ScS and direct S (δt∗ScS−S). The instantaneous frequency at the envelope peak of a seismic phase is related to the average Fourier spectral frequency of that phase. To estimate δt∗ScS−S for a given trace, we first calculate the ...

BACKGROUND Spinal cord stimulation (SCS) has been shown to provide pain relief in painful diabetic polyneuropathy (PDPN). As the vasculature system plays a great role in the pathophysiology of PDPN, a potential beneficial side-effect of SCS is peripheral vasodilation, with high frequency (HF) SCS in particular. We hypothesize that HF-SCS (500 Hz), compared with conventional (CON) or low frequen...

Stem-like cells may be integral to the development and maintenance of human cancers. Direct proof is still lacking, mainly because of our poor understanding of the biological differences between normal and cancer stem cells (SCs). Using the ErbB2 transgenic model of breast cancer, we found that self-renewing divisions of cancer SCs are more frequent than their normal counterparts, unlimited and...
