Two types of HKT transporters with different properties of Na+ and K+ transport in Oryza sativa.

Tomoaki Horie, Kumi Yoshida, Hideki Nakayama, Kenji Yamada, Shigetoshi Oiki, Atsuhiko Shinmyō
The Plant journal : for cell and molecular…
2001

It is thought that Na+ and K+ homeostasis is crucial for salt-tolerance in plants. To better understand the Na+ and K+ homeostasis in important crop rice (Oryza sativa L.), a cDNA homologous to the… (More)

CD25+CD4+ T cells in human cord blood: an immunoregulatory subset with naive phenotype and specific expression of forkhead box p3 (Foxp3) gene.

Yasushi Takahata, Akihiko Nomura, +6 authors Toshiro Hara
Experimental hematology
2004

OBJECTIVE To address the role of cord blood (CB) CD25+CD4+ T cells, the gene expressions and function of this subset were analyzed. MATERIALS AND METHODS CD25+CD4+ T cells fractionated from CB of… (More)

Global Gaussian approach for scene categorization using information geometry

Hideki Nakayama, Tatsuya Harada, Yasuo Kuniyoshi
2010 IEEE Computer Society Conference on Computer…
2010

Local features provide powerful cues for generic image recognition. An image is represented by a “bag” of local features, which form a probabilistic distribution in the feature space. The problem is… (More)

Improvement of glutathione production by metabolic engineering the sulfate assimilation pathway of Saccharomyces cerevisiae

Kiyotaka Y. Hara, Kentaro Kiriyama, Akiko Inagaki, Hideki Nakayama, Akihiko Kondo
Applied Microbiology and Biotechnology
2011

Glutathione (GSH) is a valuable tri-peptide that is widely used in the pharmaceutical, food, and cosmetic industries. Glutathione is produced industrially by fermentation using Saccharomyces… (More)

Control of signalling properties of human somatostatin receptor subtype-5 by additional signal sequences on its amino-terminus in yeast.

Yusuke Iguchi, Jun Ishii, +5 authors Akihiko Kondo
Journal of biochemistry
2010

The yeast Saccharomyces cerevisiae is known as an available host for human G-protein-coupled receptor (GPCR) ligand screening. Although several types of yeast signal sequences (SS) attached with the… (More)

Annotation order matters: Recurrent Image Annotator for arbitrary length image tagging

Jiren Jin, Hideki Nakayama
ICPR 2016
2016

Automatic image annotation has been an important research topic in facilitating large scale image management and retrieval. Existing methods focus on learning image-tag correlation or correlation… (More)

Characteristic expression of aryl hydrocarbon receptor repressor gene in human tissues: organ-specific distribution and variable induction patterns in mononuclear cells.

Junko Yamamoto, Kenji Ihara, +6 authors Toshiro Hara
Life sciences
2004

To investigate the expression of aryl hydrocarbon receptor repressor (AhRR) and related molecules in various tissues and the effects of aromatic hydrocarbons (AHs) on their expression, we developed a… (More)

Enhanced production of 2,3-butanediol by engineered Bacillus subtilis

Ranjita Biswas, Masaru Yamaoka, +4 authors Akihiko Kondo
Applied Microbiology and Biotechnology
2011

Production of 2,3-butanediol by Bacillus subtilis takes place in late-log or stationary phase, depending on the expression of bdhA gene encoding acetoin reductase, which converts acetoin to… (More)

Multimodal Gesture Recognition Using Multi-stream Recurrent Neural Network

In this paper, we present a novel method for multimodal gesture recognition based on neural networks. Our multi-stream recurrent neural network (MRNN) is a completely data-driven model that can be… (More)

Enzymatic glutathione production using metabolically engineered Saccharomyces cerevisiae as a whole-cell biocatalyst

Hideyo Yoshida, Kiyotaka Y. Hara, +6 authors Akihiko Kondo
Applied Microbiology and Biotechnology
2011

We developed a novel enzymatic glutathione (GSH) production system using Saccharomyces cerevisiae as a whole-cell biocatalyst, and improved its GSH productivity by metabolic engineering. We… (More)
