Objective Cervical spinal cord stimulation (SCS) has been found to augment cerebral blood flow (CBF) in a number of animal models. However, the effective use of SCS is hampered by a lack of understanding of its mechanism(s) of action. In this paper, we focus on the sympathetic and parasympathetic effects of SCS on CBF. Method Sprague-Dawley rats were selected for the experimental series.The ani...

OBJECTIVE Secondary cytoreductive surgery (SCS) is reported to be beneficial for patients with recurrent epithelial ovarian carcinoma (EOC). The current study is to evaluate risk factors that would affect the surgical optimal resection rate and prognosis of recurrent EOC after SCS in Chinese patients. METHODS In our study, 44 patients with recurrent EOC treated with SCS at Shandong Cancer Hos...

OBJECTIVES Electrical spinal cord stimulation (SCS) is used to treat of chronic pain, obstructive arterial-related ischemia, and anginal pain. This study investigated cerebral blood perfusion, cerebrospinal fluid (CSF) catecholamine levels, and oxidative stress before and after cervical SCS in comatose patients. METHODS We evaluated cerebral blood perfusion, catecholamine (dopamine, norepinep...

_______________________________________________________________________________________ Abstract Selection accuracy for resistance to mastitis may be increased by combining somatic cell score (SCS) and udder type into an udder health index, using genetic parameter estimates among them. A multi-trait animal model was used to estimate genetic parameters among lactation average SCS and udder type ...

BACKGROUND AND AIM Spinal cord stimulation (SCS) is a last resort treatment for chronic pain consisting of an implantable pulse generator connected to leads placed in the epidural space of the spinal cord. Effective in reducing chronic pain, however, efficacy has been found to decrease over time. Psychological factors affecting outcome of SCS have been investigated through quantitative methods,...

OBJECTIVE To assess the impact of spinal cord stimulation (SCS) on the need for acute admissions for chest pain in patients with refractory angina pectoris. DESIGN Retrospective analysis of case records. PATIENTS 19 consecutive patients implanted for SCS between 1987 and 1997. All had three vessel coronary disease, and all were in New York Heart Association functional group III/IV. METHOD...

Transplantation of Schwann cells (SCs) is a promising therapeutic strategy for spinal cord repair. SCs introduced into lesions support axon regeneration, but because these axons do not exit the transplant, additional approaches with SCs are needed. Here, we transplanted SCs genetically modified to secrete a bifunctional neurotrophin (D15A) and chondroitinase ABC (ChABC) into a subacute contusio...

BACKGROUND/AIMS Schwann cells (SCs) which were demonstrated to be responsible for axonal myelination and ensheathing are widely studied and commonly used for cell transplantation to treat spinal cord injury (SCI). We performed this meta-analysis to summarize the effects of SCs versus controls for locomotor recovery in rat models of traumatic SCI. METHODS Studies of the BBB scores after transp...

Schwann cells (SCs), the glial cells of the peripheral nervous system, cover synaptic terminals, allowing them to monitor and modulate neurotransmission. Disruption of glial coverage leads to axon degeneration and synapse loss. The cellular mechanisms that establish and maintain this coverage remain largely unknown. To address this, we labeled single SCs and performed time-lapse imaging experim...

In this paper, the performance of cellular systems in which the base-stations (BS) are randomly placed (so-called shotgun cellular system, SCS) is studied. Previous results for a uniform 2-dimensional distribution of BS are generalized to non-uniform placement of BS in any dimension. The carrier-tointerference ratio (CIR) and the carrier-to-interference-plus-noise ratio (CINR) are analyzed for ...
