Quantum Maxwell's demon in thermodynamic cycles.

Physical review. E, Statistical, nonlinear, and soft matter physics

Dong H, Xu DZ, Cai CY, Sun CP.
PMID: 21797303
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):061108. doi: 10.1103/PhysRevE.83.061108. Epub 2011 Jun 08.

We study the physical mechanism of Maxwell's demon (MD), which helps do extra work in thermodynamic cycles with the heat engine. This is exemplified with one molecule confined in an infinitely deep square potential with a movable solid wall....

Somatic embryogenesis and plant regeneration in cultured immature inflorescences of Setaria italica.

Plant cell reports

Xu ZH, Wang DY, Yang LJ, Wei ZM.
PMID: 24253473

Young inflorescence explants of Setaria italica in culture showed high capacity for regenerating plantlets through somatic embryogenesis. Embryogenic callus formation was initiated from the explants cultured on Murashige and Skoog's medium with 2 mg/l 2,4-D and 0.2-0.5 mg/l KT...

The loss-of-function of DNA methyltransferase 1 by siRNA impairs the growth of non-small cell lung cancer with alleviated side effects via reactivation of RASSF1A and APC .

Hypermethylation of tumor suppressor genes (TSGs) promoters by DNA methyltransferase (DNMT) can be observed in almost all cancers which represent a hallmark of carcinogenesis, including lung cancer. DNMT inhibitors (e.g.5-Aza-CR/CdR) reactivate TSGs to exert anti-cancer activity and have been...

The catalytic cycles of palladium-catalyzed silylation of aryl iodides, which are initiated by oxidative addition of hydrosilane or aryl iodide through three different mechanisms characterized by intermediates R

Rhodium-catalyzed synthesis of 1,2-dihydropyridine by a tandem reaction of 4-(1-acetoxyallyl)-1-sulfonyl-1,2,3-triazole.

Chemical communications (Cambridge, England)

Dai H, Yu S, Cheng W, Xu ZF, Li CY.
PMID: 28513654
Chem Commun (Camb). 2017 Jun 13;53(48):6417-6420. doi: 10.1039/c7cc02521a.

A tandem reaction of 4-(1-acetoxyallyl)-1-sulfonyl-1,2,3-triazole including formation of α-imino rhodium carbene, 1,2-migration of an acetoxy group and six electron electrocyclic ring closure was reported. The migration of the OAc group with excellent chemoselectivity was the crucial process, leading to...

Expression of hepatocyte growth factor and c-Met is characteristic of α-fetoprotein-producing colorectal adenocarcinoma: A report of three cases.

Oncology letters

Li J, Liu Y, Xu JH, Xu ZP, Zheng S, Ding KF.
PMID: 26870275
Oncol Lett. 2016 Jan;11(1):731-734. doi: 10.3892/ol.2015.3964. Epub 2015 Nov 24.

α-fetoprotein (AFP)-producing colorectal adenocarcinoma is rare and typically not well recognized. In the present study, 3 cases of AFP-producing colorectal cancer are described. All 3 of these cases demonstrated increased levels of blood AFP associated with disease progression. Only...

Contrast-Enhanced Ultrasound for the Characterization of Hepatocellular Carcinoma and Intrahepatic Cholangiocarcinoma.

Liver cancer

Liu GJ, Wang W, Lu MD, Xie XY, Xu HX, Xu ZF, Chen LD, Wang Z, Liang JY, Huang Y, Li W, Liu JY.
PMID: 26779444
Liver Cancer. 2015 Dec;4(4):241-52. doi: 10.1159/000367738. Epub 2015 Oct 21.

PURPOSE AND METHODS: The ability of contrast-enhanced ultrasound (CEUS) to differentiate between hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) is still controversial. We reviewed the CEUS imaging of 819 patients (HCC=546, ICC=273) with an established pathological diagnosis. The enhancement...

Pulmonary enteric adenocarcinoma with pancreatic metastasis: A case report.

Oncology letters

Sun WW, Xu ZH, Wang CF, Wu F, Cao JM, Cui PJ, Huang W, Jin XL, Li B, Chen KM, Gao BL, Hu JA.
