PMID: 24822436
Guang Pu Xue Yu Guang Pu Fen Xi. 2014 Feb;34(2):542-7.

In the present paper both the partial least squares (PLS) method and the calibration curve (CC) method are used to quantitatively analyze the laser induced breakdown spectroscopy data obtained from the standard alloy steel samples. Both the major and...

Combined feedforward and model-assisted active disturbance rejection control for non-minimum phase system.

PMID: 27167989
ISA Trans. 2016 Sep;64:24-33. doi: 10.1016/j.isatra.2016.04.020. Epub 2016 May 08.

Control of the non-minimum phase (NMP) system is challenging, especially in the presence of modelling uncertainties and external disturbances. To this end, this paper presents a combined feedforward and model-assisted Active Disturbance Rejection Control (MADRC) strategy. Based on the...

Contrast-enhanced ultrasound aids in the detection of prostate rhabdomyosarcoma: A case report and literature review.

Oncology letters

Guo LH, Xu HX, Fu HJ, Sun LP, Liu BJ.
PMID: 26622705
Oncol Lett. 2015 Sep;10(3):1541-1544. doi: 10.3892/ol.2015.3449. Epub 2015 Jul 01.

Prostate sarcoma is a rare malignancy with an extremely poor prognosis. The extremely low morbidity and atypical clinical symptoms contribute to a missed diagnosis. The typical features of prostate sarcoma in transrectal ultrasound (US) and magnetic resonance imaging, such...

Ligand-activated PPARδ modulates the migration and invasion of melanoma cells by regulating Snail expression.

American journal of cancer research

Ham SA, Yoo T, Hwang JS, Kang ES, Lee WJ, Paek KS, Park C, Kim JH, Do JT, Lim DS, Seo HG.
PMID: 25520859
Am J Cancer Res. 2014 Nov 19;4(6):674-82. eCollection 2014.

Peroxisome proliferator-activated receptor (PPAR) δ is implicated in the carcinogenesis of several types of cancer. However, the therapeutic efficacy of PPARδ ligands against cancer progression is unclear. Here, we showed that PPARδ modulates the migration and invasion of melanoma...

Modeling Protein Loop Structure by Cyclic Coordinate Descent-based Approach.

Journal of computational biology : a journal of computational molecular cell biology

Li H, Sun L, Luo S, Xia X, Lyu Q.
PMID: 26675269
J Comput Biol. 2016 Feb;23(2):123-136. doi: 10.1089/cmb.2015.0145. Epub 2015 Dec 16.

In both predicting protein loop structure and flexible areas in a docking interface, modeling local loop conformation plays a vital role. We address the challenge with a topological manipulation method based on the cyclic coordinate descent (CCD) algorithm. The...

Isolation, purification and properties of an R-phycocyanin from the phycobilisomes of a marine red macroalga Polysiphonia urceolata.

PloS one

Wang L, Qu Y, Fu X, Zhao M, Wang S, Sun L.
PMID: 24992364
PLoS One. 2014 Jul 03;9(7):e101724. doi: 10.1371/journal.pone.0101724. eCollection 2014.

Phycobilisomes were prepared from a marine red macroalga Polysiphonia urceolata (P. urceolata) by sucrose step-gradient ultracentrifugation. From the prepared phycobilisomes, an R-phycocyanin was isolated by gel filtration on Sephadex G-150 and then purified by ion exchange chromatography on DEAE-Sepharose...

Endovascular Therapy in Strokes with ASPECTS 5-7 May Result in Smaller Infarcts and Better Outcomes as Compared to Medical Treatment Alone.

Interventional neurology

Interv Neurol. 2015 Oct;4(1):30-7. doi: 10.1159/000438775. Epub 2015 Sep 18.

INTRODUCTION: Intra-arterial therapy (IAT) for large vessel occlusion strokes (LVOS) has been increasingly utilized. The benefit of IAT in patients with midrange Alberta Stroke Program Early Computed Tomography Score (ASPECTS) remains to be established.MATERIALS AND METHODS: This was a...

Albert-Lembert versus hybrid-layered suture in hand sewn end-to-end cervical esophagogastric anastomosis after esophageal squamous cell carcinoma resection.

Journal of thoracic disease

Feng F, Sun L, Xu G, Hong L, Yang J, Cai L, Li G, Guo M, Lian X, Zhang H.
PMID: 26716030
J Thorac Dis. 2015 Nov;7(11):1917-26. doi: 10.3978/j.issn.2072-1439.2015.11.09.

BACKGROUND: Hand sewn cervical esophagogastric anastomosis (CEGA) is regarded as preferred technique by surgeons after esophagectomy. However, considering the anastomotic leakage and stricture, the optimal technique for performing this anastomosis is still under debate.METHODS: Between November 2010 and September...

Optimal disturbance rejection for PI controller with constraints on relative delay margin.

ISA transactions

Sun L, Li D, Lee KY.
PMID: 27038886
ISA Trans. 2016 Jul;63:103-111. doi: 10.1016/j.isatra.2016.03.014. Epub 2016 Mar 30.

Performance optimization with robustness constraints is frequently encountered in process control. Motivated by the analytical difficulties in dealing with the conventional robustness index, e.g., maximum sensitivity, we introduce the relative delay margin as a good alternative, which gives much...
