Angiotensin-converting enzyme insertion/deletion polymorphism and gastric cancer: a systematic review and meta-analysis.

International journal of clinical and experimental medicine

Gan L, Liu X, Wu Z, Huang M, Zhang X, Guo W.
PMID: 26131166
Int J Clin Exp Med. 2015 Apr 15;8(4):5788-93. eCollection 2015.

Previous case-control studies on the association of the angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism with gastric cancer were controversial. A meta-analysis was conducted to further evaluate the association between polymorphism in the ACE gene I/D and gastric cancer....

Nanoscale. 2014 Sep 21;6(18):10516-23. doi: 10.1039/c4nr02308k. Epub 2014 Aug 04.

We report a new method for controlling H- and J-stacking in supramolecular self-assembly. Graphene nanosheets act as structure inducers to direct the self-assembly of a versatile organic dye, perylene into two distinct types of functional nanostructures, i.e. one-dimensional nanotubes...

Methane adsorption and dissociation on iron oxide oxygen carriers: the role of oxygen vacancies.

Physical chemistry chemical physics : PCCP

Cheng Z, Qin L, Guo M, Fan JA, Xu D, Fan LS.
PMID: 27265327
Phys Chem Chem Phys. 2016 Jun 28;18(24):16423-35. doi: 10.1039/c6cp01287f. Epub 2016 Jun 06.

We performed ab initio DFT+U calculations to explore the interaction between methane and iron oxide oxygen carriers for chemical looping reaction systems. The adsorption of CH4 and CHx (x = 0-3) radicals on α-Fe2O3(001), and the influence of oxygen...

Towards large dynamic range and ultrahigh measurement resolution in distributed fiber sensing based on multicore fiber.

Optics express

Dang Y, Zhao Z, Tang M, Zhao C, Gan L, Fu S, Liu T, Tong W, Shum PP, Liu D.
PMID: 29041702
Opt Express. 2017 Aug 21;25(17):20183-20193. doi: 10.1364/OE.25.020183.

Featuring a dependence of Brillouin frequency shift (BFS) on temperature and strain changes over a wide range, Brillouin distributed optical fiber sensors are however essentially subjected to the relatively poor temperature/strain measurement resolution. On the other hand, phase-sensitive optical...

Characterization of New Ent-kaurane Diterpenoids of Yunnan Arabica Coffee Beans.

Natural products and bioprospecting

Chu R, Wan LS, Peng XR, Yu MY, Zhang ZR, Zhou L, Li ZR, Qiu MH.

Five new ent-kaurane diterpenoids, named mascaroside III-V (1-3), and 20-nor-cofaryloside I-II (4-5), together with seven known diterpenoids, were isolated from methanol extracts of the green coffee beans of Yunnan Arabica Coffee. Their chemical structures were elucidated by extensive spectroscopic...

Domino-Like Intercellular Delivery of Undecylenic Acid-Conjugated Porous Silicon Nanoparticles for Deep Tumor Penetration.
