Apoptosis resistance in tumor cells.

Cytotechnology

Mashima T, Seimiya H, Chen Z, Kataoka S, Tsuruo T.
PMID: 19002800
Cytotechnology. 1998 Sep;27(1):293-308. doi: 10.1023/A:1008058031511.

Various antitumor agents induce apoptotic cell death in tumor cells. Since the apoptosis program in tumor cells plays a critical role in the chemotherapy-induced tumor cell killing, it is suggested that the defect in the signaling pathway of apoptosis...

Discrimination of rubber-based pressure sensitive adhesives by size exclusion chromatography.

Forensic science international

Kumooka Y.
PMID: 17052877
Forensic Sci Int. 2007 Aug 24;171(1):5-8. doi: 10.1016/j.forsciint.2006.09.005. Epub 2006 Oct 18.

In this report, three pairs of rubber-based pressure sensitive adhesives were analyzed by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), attenuated total reflectance Fourier transform infrared spectrometry (ATR/FT-IR) and size exclusion chromatography (SEC). The size exclusion chromatograph was equipped with a refractive...

Training in laparoscopic renal surgery, in a few weeks of intense exposure.

Journal of pediatric urology

Hennayake S, Jayawardhena D, Kumara S, Sakelaris G.
PMID: 18947555
J Pediatr Urol. 2005 Aug;1(4):295-9. doi: 10.1016/j.jpurol.2005.01.010. Epub 2005 Mar 19.

OBJECTIVES: Laparoscopic renal surgery has only recently become popular in the UK and, still, only a handful of pediatric urologists are offering the laparoscopic approach to their patients; therefore, there are only limited places available for training in this...

Probing molecular structure at interfaces for comparison with bulk solution behavior: water/2-propanol mixtures monitored by vibrational sum frequency spectroscopy.

Journal of the American Chemical Society

Kataoka S, Cremer PS.
PMID: 16620125
J Am Chem Soc. 2006 Apr 26;128(16):5516-22. doi: 10.1021/ja060156k.

The orientation of the isopropyl group at the liquid/vapor interface in 2-propanol/water binary mixtures was studied by vibrational sum frequency spectroscopy. The CH(3) stretch modes of the two methyl groups were used to determine the molecule's orientation by employing...

Evidence of Reentrance of Glycolate Carbon into the Photosynthetic Carbon Reduction Cycle in Photosynthesizing Euglena gracilis Z.

Plant physiology

Yokota A, Asama K, Kitaoka S.
PMID: 16667715
Plant Physiol. 1990 Sep;94(1):388-91. doi: 10.1104/pp.94.1.388.

Aminooxyacetate induced excretion of glycolate from air-grown cells of Euglena gracilis in both air and 1% CO(2) atmospheres. The rate of the excretion reached 70% of the photosynthetic rate in the air on a carbon basis, and was 10%...

Differences between the internal energy depositions induced by collisional activation and by electron transfer of W(CO)6(2+) ions on collision with Ar and K targets.

The Journal of chemical physics

Hayakawa S, Kitaguchi A, Kameoka S, Toyoda M, Ichihara T.
PMID: 16784287
J Chem Phys. 2006 Jun 14;124(22):224320. doi: 10.1063/1.2204598.

Doubly charged tungsten hexacarbonyl W(CO)(6) (2+) ions were made to collide with Ar and K targets to give singly and doubly charged positive ions by collision-induced dissociation (CID). The resulting ions were analyzed and detected by using a spherical...

Production of inhibitory polyclonal antibodies against cytochrome P450s.

Drug metabolism and pharmacokinetics

Ng PS, Imaoka S, Hiroi T, Osada M, Niwa T, Kamataki T, Funae Y.
PMID: 15618732
Drug Metab Pharmacokinet. 2003;18(3):163-72. doi: 10.2133/dmpk.18.163.

Nine different antibodies against P450 isoforms were prepared using purified cytochrome P450s (P450) expressed in E. coli. Purified isozymes were injected into rabbits to raise specific antibody. The resulting antibodies were characterized for their specificity and sensitivity through each...

Hierarchical cluster analysis as a tool for preliminary discrimination of ATR-FT-IR spectra of OPP acrylic and rubber-based adhesives.

Forensic science international

Kumooka Y.
PMID: 19481889
Forensic Sci Int. 2009 Aug 10;189(1):104-10. doi: 10.1016/j.forsciint.2009.04.025. Epub 2009 May 29.

It is difficult to discriminate colorless and transparent oriented poly(propylene) (OPP) packaging tapes by the physical measurements of the backings. They are normally discriminated by the analysis of the adhesives. In the present study acrylic and rubber-based adhesives of...

[Use experience and problems in the optimization of intensity modulated radiation therapy (IMRT)--Focus on head & neck].

Ariji T, Ueda T, Kitoh S, Goka T, Kameoka S, Kohno R, Nishio T, Kawashima M.
PMID: 20953103
Nihon Hoshasen Gijutsu Gakkai Zasshi. 2010 Aug 20;66(8):879-84. doi: 10.6009/jjrt.66.879.

We present the main points of the optimization in IMRT. The skin surface of the planned target volume was reduced by a few millimeters, in view of the limitations of a calculation grid in accurately estimating the influence of...

Nanometer-sized domains in Langmuir-Blodgett films for patterning SiO2.

Langmuir : the ACS journal of surfaces and colloids

Kataoka S, Takeuchi Y, Endo A.
PMID: 20369867
