PMID: 18969816
Talanta. 2005 Jan 30;65(2):430-6. doi: 10.1016/j.talanta.2004.06.034.

A fluorescence immunoassay for human IgG (Ag) was developed using a pH-sensitive polymer prepared by thermal initiation or redox initiation polymerization as a carrier. In the competitive immunoassay, appropriate quantity of Ag was immobilized on the polymer and the...

Interfacial forces and Marangoni flow on a nematic drop retracting in an isotropic fluid.

Journal of colloid and interface science

Yue P, Feng JJ, Liu C, Shen J.
PMID: 16122548
J Colloid Interface Sci. 2005 Oct 01;290(1):281-8. doi: 10.1016/j.jcis.2005.04.018.

Nematic-isotropic interfaces exhibit novel dynamics due to anchoring of the liquid crystal molecules on the interface. The objective of this study is to demonstrate the consequences of such dynamics in the flow field created by an elongated nematic drop...

New technique in hepatic parenchymal transection for living related liver donor and liver neoplasms.

HPB : the official journal of the International Hepato Pancreato Biliary Association

Gruttadauria S, Doria C, Vitale CH, Mandala' L, Magnone M, Fung JJ, Marino IR.
PMID: 18333059
HPB (Oxford). 2004;6(2):106-9. doi: 10.1080/13651820410025093.

BACKGROUND: Many different surgical techniques have been described for hepatic parenchymal transection. A retrospective analysis of perioperative mortality, length of hospitalization and blood transfused during operation in two patient groups undergoing liver resection was carried out. In group A,...

PdEDTA held in an ionic liquid brush as a highly efficient and reusable catalyst for Suzuki reactions in water.

The Journal of organic chemistry

Wei JF, Jiao J, Feng JJ, Lv J, Zhang XR, Shi XY, Chen ZG.
PMID: 20560571
J Org Chem. 2009 Aug 21;74(16):6283-6. doi: 10.1021/jo900481y.

An efficient and reusable catalyst with PdEDTA immobilized in an ionic liquid brush and a green procedure have been developed for coupling aryl iodides and bromides with phenylboronic acid. These reactions were conducted in water under aerobic conditions with...

A novel gene required for male fertility and functional CATSPER channel formation in spermatozoa.

Nature communications

Chung JJ, Navarro B, Krapivinsky G, Krapivinsky L, Clapham DE.
PMID: 21224844
Nat Commun. 2011 Jan 11;2:153. doi: 10.1038/ncomms1153.

Calcium signalling is critical for successful fertilization. In spermatozoa, capacitation, hyperactivation of motility and the acrosome reaction are all mediated by increases in intracellular Ca(2+). Cation channels of sperm proteins (CATSPERS1-4) form an alkalinization-activated Ca(2+)-selective channel required for the...

3-(2-Thioxo-1,3-dithiol-4-ylsulfan-yl)-propane-nitrile.

Acta crystallographica. Section E, Structure reports online

Zhao BT, Ding JJ, Qu GR.

Acta Crystallogr Sect E Struct Rep Online. 2008 Oct 04;64:o2078. doi: 10.1107/S1600536808031711.

The title compound, C(6)H(5)NS(4), consists of a planar 2-thioxo-1,3-dithiol-4-ylsulfanyl unit [maximum deviation from the ring plane = 0.0325 (2) Å], with a cyano-ethyl-sulfanyl substituent in the 4-position. In the crystal structure, weak inter-molecular C-H⋯S hydrogen bonds together with S⋯N...

Kaposi's sarcoma in two primary liver allograft recipients occurring under FK506 immunosuppression.

Clinical transplantation

Clin Transplant. 1993 Jan 01;7:188-194.

Of 1463 liver allograft recipients receiving the combination of FK506 and steroids as their primary immunosuppressive regimen, 2 patients developed Kaposi's sarcoma. Although previously described as a complication of organ transplantation, this is the first case report of Kaposi's...

Wavelength-tunable and pulse-width variable Fourier domain mode-locking lasers.

Optics letters

Opt Lett. 2011 Dec 15;36(24):4752-4. doi: 10.1364/OL.36.004752.

In this study, wavelength-tunable and pulse-width variable Fourier domain mode-locking lasers were developed with a repetition rate of 60.9 kHz. A spectral laser tuning range of over 100 nm was achieved by tuning the offset voltage to a fiber...

Two-dimensional orthogonal DCT expansion in trapezoid and triangular blocks and modified JPEG image compression.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society
