Anomalous Pauli electron states for magnetic fields with tails (2007)

P. Exner, M. Hirokawa, O. Ogurisu

We consider a two-dimensional electron with an anomalous magnetic moment, g? 2, interacting with a nonzero magnetic field B perpendicular to the plane which gives rise to a flux F. Recent results...

A model of interband radiative transitions (2000)

Dittrich, J., Exner, P., Hirokawa, M.

We consider a simple model which is a caricature of a crystal interacting with a radiation field. The model has two bands of continuous spectrum and the particle can pass from the upper one to the...

Analysis of discordant test results among five second-generation assays for anti-hepatitis C virus antibodies also tested by polymerase chain reaction-RNA assay and other laboratory and clinical tests for hepatitis.

Nakagiri, I, Ichihara, K, Ohmoto, K, Hirokawa, M, Matsuda, N

The diagnostic performances of five commercially available second-generation assays for anti-hepatitis C virus antibody, two enzyme-linked immunosorbent assays, one enzyme immunoassay, and two...

Lithium associated autoimmune thyroiditis.

Shimizu, M, Hirokawa, M, Manabe, T, Shimozuma, K, Sonoo, H, Harada, T

A case of autoimmune thyroiditis after long term treatment with lithium is described in a 29 year old Japanese woman with manic depression. Positive serum antithyroglobulin and antimicrosomal...

Beta 2 microglobulin haemodialysis related amyloidosis: distinctive gross features of gastrointestinal involvement.

Shimizu, M, Manabe, T, Matsumoto, T, Monobe, Y, Hirokawa, M, Moriya, T, ...

Two cases of beta 2 microglobulin amyloidosis following long term haemodialysis found during necropsy are reported. The patients were 59 and 65 year old Japanese men, respectively. In both cases,...

Histological assessment of chronic pancreatitis at necropsy.

Shimizu, M, Hirokawa, M, Manabe, T

AIMS: To evaluate the histological criteria used to diagnose chronic pancreatitis; and to assess interobserver variation among general pathologists. METHODS: Forty five cases of chronic pancreatitis...

Intraepithelial haemorrhage of the oesophagus: a terminal event in haematological disorders.

Shimizu, M, Matsumoto, T, Hirokawa, M, Monobe, Y, Iida, M, Manabe, T

AIMS: To investigate the clinicopathological findings in cases with intraepithelial haemorrhage of the oesophagus (IHO). METHODS: Necropsy records and the histopathology findings in the oesophagus...

Signal transduction by B7/BB1 expressed on activated T lymphocytes: cross-linking of B7/BB1 induces protein tyrosine phosphorylation and synergizes with signalling through T-cell receptor/CD3.

Hirokawa, M, Kitabayashi, A, Kuroki, J, Miura, A B

We report here that B7/BB1 molecules expressed on activated T lymphocytes are involved in signal transduction. Anti-B7/BB1 monoclonal antibody (mAb) enhanced allogeneic proliferative responses...

Direct measurement of acid permeation into rat oesophagus

Tanaka, S, Chu, S, Hirokawa, M, Montrose, M H, Kaunitz, J D

Background and aims: The early responses of the oesophageal mucosa to acid perfusion may predict subsequent pathology. Mucosal responses to luminal acid may result either from acid permeating through...

Lymphokine activity production in graft-versus-host reactions across minor histocompatibility antigen barriers.

Hirokawa, M, Takatsu, H, Ohshima, A, Chubachi, A, Kudo, K, Niitsu, H, ...

Activated T cells responding to murine minor histocompatibility antigens (HA) were characterized according to the patterns of lymphokine activity production. Although B10.D2/nSN and BALB/c are...

Transmural pressure induces IL-6 secretion by intestinal epithelial cells

KISHIKAWA, H, MIURA, S, YOSHIDA, H, HIROKAWA, M, NAKAMIZO, H, HIGUCHI, H, ...

Although intestinal epithelial cells (IECs) are known as an important source for IL-6, it is not known whether mechanical forces affect IL-6 production. We investigated how transmural pressure...

Reexamination of Stackelberg Leadership: Fixed Supply Contracts Under Demand Uncertainty

Hirokawa, M., Sasaki, D.

This paper shows an endogenous Stackelberg leader-follower relation that stems purely from commitment, not from chronological order of entry. We consider a symmetric duopoly game with a priori demand...

Endogenously Asynchronous Entries Into an Uncertain Industry

Hirokawa, M, Sasaki, D.

In the presence of demand uncertainty, a priori identical firms may voluntarily choose asynchronous timing of entries. We formulate a duopoly model where two firms compete during many marketing...

Endogenous Co-Leadership When Demand Is Unknown.

Hirokawa, M., Sasaki, D.

Consider an oligopolistic industry where demand uncertainty resolves after at least one firm has engaged in production. Those firms who produce first behave as simultaneous leaders (co-leaders),...

Skewed T cell receptor repertoire of Vδ1+ γδ T lymphocytes after human allogeneic haematopoietic stem cell transplantation and the potential role for Epstein–Barr virus-infected B cells in clonal restriction

Fujishima, N, Hirokawa, M, Fujishima, M, Yamashita, J, Saitoh, H, Ichikawa, Y, ...

The proliferation of Vδ1+ γδ T lymphocytes has been described in various infections including human immunodeficiency virus (HIV), cytomegalovirus (CMV) and malaria. However, the antigen...

Takano, T, Ito, Y, Hirokawa, M, Yoshida, H, Miyauchi, A

Frequency of a BRAFV600E mutation in anaplastic thyroid carcinoma, which is thought to be derived mainly from papillary carcinoma by multi-step carcinogenesis, is much lower than that in papillary...
