We analyzed clinical usefulness of the high resolution imaging system in a hybrid operation room (OR) for posterior lumbar interbody fusion. A total of 17 patients with lumbar spondylolisthesis between February 2014 and August 2016 were included. Multi-axis imaging system in a hybrid OR was used in 12 patients (hybrid OR group); the conventional C-arm fluoroscopy, in 5 patients (C-arm group). T...

conclusions: use of ginger was effective at decreasing postoperative nausea. ginger could be used as a safe antiemetic drug at post operation. results: mean nausea score at 2 hours post operation was significantly lower in the experimental group (p= 0.04). mean nausea score at 4 and 6 hours post operation was lower in the experimental group; however, there was no significant difference between ...

background: we investigated the effects of cigarette smoking in non-per os (npo) period on volume and ph of gastric contents in smoker male patients. methods: in a prospective cohort study, 86 male smoker patients undergoing elective non-abdominal surgery under general anesthesia, were surveyed. they were npo for at least 8-12 hrs. prior to surgery without direction to smoking. then they were d...

In the last decade quantum cascade lasers (QCLs) have become the most widely used source of mid-infrared radiation, finding large scale applications because of their wide tunability and overall high performance. However far-infrared (terahertz) QCLs have lagged behind in terms of performance and impact due to the inability so far of achieving room temperature operation. Here we review recent re...

Erbium-doped fiber is a gain medium exhibiting homogeneous line broadening at room temperature, while a semiconductor optical amplifier has a dominant feature of inhomogeneous line broadening. In this work, a semiconductor optical amplifier is incorporated into the cavity of an erbium-doped fiber ring laser to form a hybrid gain medium. Theoretical analysis shows that such a gain medium support...

opiates such as morphine are one of the most effective classes of medication prescribed to treat both acute and chronic pain.they act to suppress pain through mu-receptor activation on primary afferent nerve fibers, dorsal horn neurons and supraspinal pain center neorons. when morphine is administered epidurally, it diffuses to the cord substance, producing analgesia [1],the aim of this study w...

Photonic crystal slab enables us to form an ultrasmall laser cavity with a modal volume close to the diffraction limit of light. However, the thermal resistance of such nanolasers, as high as 10(6) K/W, has prevented continuous-wave operation at room temperature. The present paper reports on the first successful continuous-wave operation at room temperature for the smallest nanolaser reported t...

We have used a two-dimensional drift-diffusion simulator, augmented by including accurate low-field mobility curves obtained by the Monte Carlo method, to study the operation of SiC MOSFETs both at room and high temperatures. A comparison with Si MOSFETs at room temperature is performed. Although drain current was higher in Si MOSFETs, SiC MOSFETs showed lower saturation conductance values. The...

Let PSL2(R) be a cocompact arithmetic triangle group, i.e. a triangle Fuchsian group that arises from the unit group of a quaternion algebra over a totally real number eld. We introduce CM points de ned on the Shimura curve quotient XC = nH, and we algorithmically apply the Shimura reciprocity law to compute these points and their Galois conjugates so as to recognize them as purported algebraic...
