Theoretical Study of Network Formation and Mechanical Properties of Physical Gels with a Well-Defined Junction Structure.

The journal of physical chemistry. B

Ozaki H, Koga T.
PMID: 27431804
J Phys Chem B. 2016 Aug 11;120(31):7745-53. doi: 10.1021/acs.jpcb.6b05183. Epub 2016 Aug 01.

A statistical-mechanical theory of thermoreversible gelation considering loops for the system consisting of bifunctional polymer units carrying A functional groups and trifunctional units carrying B functional groups at their ends is constructed. We obtain the sol-gel transition line and...

Diffuse amyloid goiter (AG) is an entity characterized by the deposition of amyloid in the thyroid gland. AG may be associated with either primary or secondary amyloidosis. Secondary amyloidosis is rarely caused by inflammatory bowel diseases. Secondary amyloidosis is...

Two closely related species differ in their regional genetic differentiation despite admixing.

AoB PLANTS

Schmidt L, Fischer M, Oja T.
PMID: 29479408
AoB Plants. 2018 Jan 29;10(1):ply007. doi: 10.1093/aobpla/ply007. eCollection 2018 Feb.

Regional genetic differentiation within species is often addressed in evolutionary ecology and conservation biology. Here, we address regional differentiation in two closely related hybridizing taxa, the perennial sedges

Field performance and cytology of protoplast-derived rice (Oryza sativa): high yield and low degree of variation of four japonica cultivars.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Ogura H, Kyozuka J, Hayashi Y, Koba T, Shimamoto K.
PMID: 24240226
Theor Appl Genet. 1987 Sep;74(5):670-6. doi: 10.1007/BF00288869.

Protoplast-derived rice plants of four Japanese cultivars, Nipponbare, Fujisaka 5, Norin 14 and Iwaimochi were individually cultivated in a submerged paddy field. They exhibited more stems, which resulted in more panicles than respective control plants. Other characteristics of protoplast-derived...

Coexistence of ordered and disordered phases in a nearly symmetric diblock copolymer near an order-disorder transition point.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Koga T, Koga T, Hashimoto T.
PMID: 11969941
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Aug;60(2):R1154-7. doi: 10.1103/physreve.60.r1154.

We investigated the phase behavior near the order-disorder transition (ODT) temperature in a nearly symmetric diblock copolymer, using ultra-small-angle x-ray scattering method. In a narrow temperature range very close to the ODT temperature, we observed the scattering profiles that...

An alternative synthetic route of [3(5)](1,2,3,4,5)cyclophane, and structural properties of multibridged [3(n)]cyclophanes and their charge-transfer complexes in the solid state.

Journal of the American Chemical Society

Yasutake M, Koga T, Sakamoto Y, Komatsu S, Zhou M, Sako K, Tatemitsu H, Onaka S, Aso Y, Inoue S, Shinmyozu T.
PMID: 12188678
J Am Chem Soc. 2002 Aug 28;124(34):10136-45. doi: 10.1021/ja012363k.

To develop an improved synthetic route to [3(6)](1,2,3,4,5,6)cyclophane (CP) 2, a more practical synthetic route to [3(5)](1,2,3,4,5)CP 3 than the original one was developed, which started from [3(2)](1,3)CP 7 via [3(4)](1,2,4,5)CP 5. The fundamental structural parameters of [3(n)]CPs (n...

Immunohistochemical analysis of connexin43 expression in infertile human testes.

Acta histochemica et cytochemica

Matsuo Y, Nomata K, Eguchi J, Aoki D, Hayashi T, Hishikawa Y, Kanetake H, Shibata Y, Koji T.
PMID: 17653298
Acta Histochem Cytochem. 2007 Jul 03;40(3):69-75. doi: 10.1267/ahc.07001.

Connexin43 (Cx43) is abundantly expressed in mammalian testes and implicated in the regulation of cell-to-cell interaction between germ cells and Sertoli cells, which is essential to the normal process of spermatogenesis. In the present study, we investigated the relation...

Supercritical fluid processing of polymer thin films: an X-ray study of molecular-level porosity.

Advances in colloid and interface science

Koga T, Jerome J, Rafailovich MH, Chu B, Douglas J, Satija S.
PMID: 17239334
Adv Colloid Interface Sci. 2006 Dec 21;128:217-26. doi: 10.1016/j.cis.2006.11.020. Epub 2007 Jan 17.

This paper reviews our recent experimental results that address the effects of solvent density inhomogeneities in supercritical carbon dioxide (scCO(2)) on polymer thin film processing. The key phenomenon is excess sorption of CO(2) molecules into polymer thin films even...

Bounds to average interelectronic angles in Hartree-Fock theory of atoms.

The Journal of chemical physics

Koga T, Matsuyama H.
PMID: 15260754
J Chem Phys. 2004 Aug 01;121(5):2016-9. doi: 10.1063/1.1767518.

The average interelectronic is the expectation value of the angle thetaij (0 < or = thetaij < or = pi) subtended by the position vectors ri and rj of a pair of electrons i and j. In the Hartree-Fock...
