Which has more stem-cell characteristics: Müller cells or Müller cells derived from in vivo culture in neurospheres?.

American journal of translational research

Ji HP, Xiong Y, Zhang ED, Song WT, Gao ZL, Yao F, Sun H, Zhou RR, Xia XB.
PMID: 28337288
Am J Transl Res. 2017 Feb 15;9(2):611-619. eCollection 2017.

OBJECTIVE: Müller cells can be acquired from in vitro culture or a neurosphere culture system. Both culture methods yield cells with progenitor-cell characteristics that can differentiate into mature nervous cells. We compared the progenitor-cell traits of Müller cells acquired...

A Retina Inspired Model for Enhancing Visibility of Hazy Images.

Frontiers in computational neuroscience

Zhang XS, Gao SB, Li CY, Li YJ.
PMID: 26733857
Front Comput Neurosci. 2015 Dec 22;9:151. doi: 10.3389/fncom.2015.00151. eCollection 2015.

The mammalian retina seems far smarter than scientists have believed so far. Inspired by the visual processing mechanisms in the retina, from the layer of photoreceptors to the layer of retinal ganglion cells (RGCs), we propose a computational model...

Sapphire-based graphene saturable absorber for long-time working femtosecond lasers.

Optics letters

Xu SC, Man BY, Jiang SZ, Feng DJ, Gao SB, Chen CS, Liu M, Yang C, Zhang C, Bi D, Liu FY, Meng X.
PMID: 24784083
Opt Lett. 2014 May 01;39(9):2707-10. doi: 10.1364/OL.39.002707.

We report a long-time working femtosecond laser using metal-free sapphire-based graphene as a saturable absorber (SA). The sapphire-based graphene yielded excellent nonlinear saturable absorption properties and was demonstrated to be suitable as an SA for an ultrafast solid-state laser....

Expansion of myeloid-derived suppressor cells from peripheral blood decreases after 4-week antiviral treatment in patients with chronic hepatitis C.

Myeloid-derived suppressor cells (MDSCs) are one of the most important regulators of anti-tumor T-cell responses in cancers. This study aimed to investigate MDSCs in the peripheral blood of patients with chronic hepatitis C (CHC) before and after 4-week treatment...

Genetic alteration and misexpression of Polycomb group genes in hepatocellular carcinoma.

American journal of cancer research

Gao SB, Sun SL, Zheng QL, Zhang L, Zhu Y, Jin GH, Xue LX.
PMID: 26693053
Am J Cancer Res. 2015 Sep 15;5(10):2969-79. eCollection 2015.

Although the abnormal expression of Polycomb-group (PcG) proteins is closely associated with carcinogenesis and the clinicopathological features of hepatocellular carcinoma (HCC), the genetic mutation profile of PcG genes has not been well established. In this study of human HCC...

Fermi resonance is a phenomenon of molecular vibrational coupling and energy transfer occurred between different groups of a single molecule or neighboring molecules. Many properties of Fermi resonance under different external fields, the investigation method of Raman spectroscopy as...

Effect of osteopontin on the mRNA expression of ADAMTS4 and ADAMTS5 in chondrocytes from patients with knee osteoarthritis.

Experimental and therapeutic medicine

Gao SG, Zeng C, Song Y, Tian J, Cheng C, Yang T, Li H, Zhang FJ, Lei GH.
