Programmed cell death 1 (PD-1) receptor-ligand interaction is a major pathway that is often hijacked by tumors to suppress immune control. Immunoscore (IS), a combinational index of CD3 and CD8 tumor-infiltrating lymphocyte (TIL) density in the tumor's center and...

Impact force measurement of a spherical body dropping onto a water surface.

The Review of scientific instruments

Araki R, Takita A, Ishima T, Kawashima H, Pornsuwancharoen N, Punthawanunt S, Carcasona E, Fujii Y.
PMID: 25085174
Rev Sci Instrum. 2014 Jul;85(7):075108. doi: 10.1063/1.4878629.

We propose a method for measuring the impact force of a spherical body dropping onto a water surface. The velocity of the center of gravity of a metal spherical body, in which a cube corner prism is embedded so...

Downregulation of miR-186 is associated with metastatic recurrence of gastrointestinal stromal tumors.

Oncology letters

Niinuma T, Kai M, Kitajima H, Yamamoto E, Harada T, Maruyama R, Nobuoka T, Nishida T, Kanda T, Hasegawa T, Tokino T, Sugai T, Shinomura Y, Nakase H, Suzuki H.
PMID: 29113198
Oncol Lett. 2017 Nov;14(5):5703-5710. doi: 10.3892/ol.2017.6911. Epub 2017 Sep 08.

Although dysregulation of microRNAs (miRNAs/miRs) is a common feature of human malignancies, its involvement in gastrointestinal stromal tumors (GISTs) is not fully understood. The present study aimed to identify the miRNAs that perform a role in GIST metastasis. miRNA...

Voronoi space division of a polymer: topological effects, free volume, and surface end segregation.

The Journal of chemical physics

Tokita N, Hirabayashi M, Azuma C, Dotera T.
PMID: 15267311
J Chem Phys. 2004 Jan 01;120(1):496-505. doi: 10.1063/1.1629678.

In order to investigate the topological effects of chain molecules, united-atom molecular dynamics simulations of a 500-mer polyethylene linked by 50 hexyl groups (a grafted polymer having 52 ends) are carried out and analyzed in terms of Voronoi space...

n-type organic field-effect transistors with very high electron mobility based on thiazole oligomers with trifluoromethylphenyl groups.

Journal of the American Chemical Society

Ando S, Murakami R, Nishida J, Tada H, Inoue Y, Tokito S, Yamashita Y.
PMID: 16248617
J Am Chem Soc. 2005 Nov 02;127(43):14996-7. doi: 10.1021/ja055686f.

Novel thiazole oligomers and thiazole/thiophene co-oligomers with trifluoromethylphenyl groups were developed as n-type semiconductors for OFETs. They showed excellent n-type performances with high electron mobilities. A 5,5'-bithiazole with trifluoromethylphenyl groups forms a closely packed two-dimensional columnar structure leading to...

Weak values of electron spin in a double quantum dot.

Physical review letters

Romito A, Gefen Y, Blanter YM.
PMID: 18352406
Phys Rev Lett. 2008 Feb 08;100(5):056801. doi: 10.1103/PhysRevLett.100.056801. Epub 2008 Feb 05.

We propose a protocol for a controlled experiment to measure a weak value of the electron's spin in a solid state device. The weak value is obtained by a two step procedure--weak measurement followed by a strong one (postselection),...

Self-organization of decaying surface corrugations: a numerical study.

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

Bonito A, Nochetto RH, Quah J, Margetis D.
PMID: 19518406
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 May;79(5):050601. doi: 10.1103/PhysRevE.79.050601. Epub 2009 May 11.

We study numerically the interplay of surface topography and kinetics in the relaxation of crystal surface corrugations below roughening in two independent space dimensions. The kinetic processes are isotropic diffusion of adatoms across terraces and attachment-detachment of atoms at...

Unusual swelling of HPC in toluene forming a microspherical domain structure that causes Christiansen scattering coloration.

Langmuir : the ACS journal of surfaces and colloids

Edo S, Okoshi K, Kang S, Tokita M, Kaneko T, Watanabe J.
PMID: 19731958
Langmuir. 2010 Feb 02;26(3):1743-6. doi: 10.1021/la902698f.

The unusual swelling behavior of hydroxypropyl cellulose (HPC) by toluene is described. At temperatures as high as 100 degrees C, toluene molecules can enter the HPC film up to the weight fraction of 55%; however, they are segregated from...

Curvature analysis reveals new functions for ethylene signalling pathway in shape determination of seed poles and root apices.

Plant signaling & behavior

Tocino A, Cervantes E.
PMID: 19513223

IN MATHEMATICS, CURVATURE IS AN IMPORTANT MAGNITUDE IN THE DESCRIPTION OF PLANE CURVES: it represents the rate of change of direction of a curve with respect to distance along the curve. By looking at root tips of Arabidopsis, we...

Strain sensitivity and durability in p-type and n-type organic thin-film transistors with printed silver electrodes.

Scientific reports

PMID: 23788235
Sci Rep. 2013;3:2048. doi: 10.1038/srep02048.

Mechanical flexibility and compatibility of printing processes are key advantage that organic electronic devices have over conventional inorganic devices. However, one of the major remaining issues for organic devices is insufficient mechanical durability of printed electrodes. Here we have...

We have synthesized a new photochromic compound that exhibits unusual negative photochromism, in which the stable colored species photochemically converts into the metastable colorless species via a short-lived radical. This compound has a 1,1'-binaphthyl moiety bridging the two diphenylimidazole...
