For a multiple-input-single-output (MISO) cooperative communication system, we consider a beamforming design problem by taking into account trust degrees between nodes. For given trust degrees, we design the optimal transmit beamformer in terms of an expected achievable rate as a linear combination of channel vectors w...
A parametric study of a 10.6-micro laser radar using heterodyne detection is presented. Returns from various noncooperative targets have been obtained at ranges of up to 8 km. The radar equipment uses an offset local oscillator frequency in order to avoid homodyne operation. Measurements of signal-to-noise ratio over a...
Intrinsically disordered proteins (IDPs) are important for health and disease, yet their lack of net structure precludes an understanding of their function using classical methods. Gas-phase techniques provide a promising alternative to access information on the structure and dynamics of IDPs, but the fidelity to which...

OBJECTIVE
To explore the signal transduction pathway mediated by thrombopoietin (TPO) in the inflammation model of microglia induced by lipopolysaccharide (LPS).
METHODS
The inflammation model of microglia BV2 cells was prepared by LPS of 0.5 and 1.0 μg/mL stimulation. The expression of TPO and ERK mRNA in BV2 cells was detected by real time quantitative PCR. Western blot was used to evaluate the expression of TPO and ERK protein in BV2 cells. TPO and IL-6 contents in the culture super...
RESULTS
LPS stimulation increased significantly the mRNA and protein expression of TPO and ERK in BV2 cells, especially at the concentration of 1.0 μg/mL for 12 hrs stimulation. There was a significant positive correlation between the mRNA and protein expression of TPO and ERK.
CONCLUSIONS
Signal transduction pathway of ERK1/2 participates in the activation of TPO in inflammatory injury of BV2 cells.Self-focusing and defocusing of the self-similar π-pulses in the gain media

BACKGROUND
Novel regional techniques, including the adductor canal block (ACB) and the local anesthetic infiltration between the popliteal artery and capsule of the knee (IPACK) block, provide an alternative approach for controlling pain following total knee arthroplasty (TKA). This study compared 3 regional techniques (femoral n...
METHODS
All patients had a continuous perineural infusion, either FNC block or ACB. Patients in the IPACK block groups also received a single injection 30-mL IPACK block of 0.25% ropivacaine. Pain scores and opioid consumption were recorded at postanesthesia care unit discharge and again at 8-hour intervals for 48 hours. Physi...
RESULTS
We found no significant differences in the 3 groups with regard to baseline patient demographics. Although we observed no differences in pain scores between the 3 groups, opioid consumption was significantly reduced in the FNC with IPACK group. Physical therapy performance was significantly better on POD 1 in the ACB w...
CONCLUSION
This study demonstrated that an IPACK block reduced opioid consumption by providing effective supplemental analgesia following TKA compared to the FNC-only technique. ACB with IPACK provided equivalent analgesia and improved physical therapy performance, allowing earlier hospital discharge.An End to the Yen to List

BACKGROUND
The management of spine metastases is an increasing concern for spine surgeons. Their treatment is mainly palliative with the goal to preserve or restore the patients' quality of life. Many minimally invasive techniques have been introduced with the aim to reduce the morbidity associated with more traditional open appr...
METHODS
In this prospective study, we included all patients who underwent the percutaneous placement of pedicle screws in our institution between January 2008 and June 2014, for the palliative treatment of a symptomatic thoracolumbar spine metastasis. All patients had a normal examination. Postoperative radiation therapy was p...
RESULTS
Forty-four patients have been included. There were 26 men and 18 women, with a mean age of 57.3 years (range 36-79 years). The mean operative time was 85 minutes (range 47-124 min), and the estimated blood loss was inferior to 100 mL in all cases. The mean length of hospital stay was 5.2 days (range 3-18 days). All pat...
CONCLUSIONS
As the treatment of spine metastases is largely palliative, minimally invasive techniques should be discussed first to limit the impact of surgery in critical patients. Long-segment percutaneous screw fixation followed by early radiation therapy, appears to be a safe and effective treatment option to ensure solid and d...
