Anthraquinone Production by Cell Suspension Cultures of Rubia akane Nakai.

Bioscience, biotechnology, and biochemistry

Mizutani H, Hashimoto O, Nakashima R, Nagai J.
PMID: 27393171
Biosci Biotechnol Biochem. 1997 Jan;61(10):1743-4. doi: 10.1271/bbb.61.1743.

The effects of various plant growth regulators and nutrients on cell growth and anthraquinone production in cell suspension cultures of Rubia akane Nakai were investigated. Use of an optimized medium resulted in a two-fold increase in the anthraquinone content....

Evaluation of channel capacities of OAM-based FSO link with real-time wavefront correction by adaptive optics.

Li M, Cvijetic M, Takashima Y, Yu Z.
PMID: 25607082
Opt Express. 2014 Dec 15;22(25):31337-46. doi: 10.1364/OE.22.031337.

We have evaluated the channel capacity of OAM-based FSO link under a strong atmospheric turbulence regime when adaptive optics (AO) are employed to correct the wavefront phase distortions of OAM modes. The turbulence is emulated by the Monte-Carlo phase...

Development of n-type cobaltocene-encapsulated carbon nanotubes with remarkable thermoelectric property.

Scientific reports

Fukumaru T, Fujigaya T, Nakashima N.
PMID: 25608478
Sci Rep. 2015 Jan 22;5:7951. doi: 10.1038/srep07951.

Direct conversion from heat to electricity is one of the important technologies for a sustainable society since large quantities of energy are wasted as heat. We report the development of a single-walled carbon nanotube (SWNT)-based high conversion efficiency, air-stable...

OBJECTIVES: Adenocarcinoma is known to be associated with ulcerative colitis, but the diagnosis is sometimes challenging, both clinically and pathologically.METHODS AND RESULTS: We present a case of extremely well-differentiated adenocarcinoma associated with ulcerative colitis, in which preoperative diagnosis was...

Limitations in the spectral method for graph partitioning: Detectability threshold and localization of eigenvectors.

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

Kawamoto T, Kabashima Y.
PMID: 26172750
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Jun;91(6):062803. doi: 10.1103/PhysRevE.91.062803. Epub 2015 Jun 08.

Investigating the performance of different methods is a fundamental problem in graph partitioning. In this paper, we estimate the so-called detectability threshold for the spectral method with both un-normalized and normalized Laplacians in sparse graphs. The detectability threshold is...

Concentrations of Radiocesium in Local Foods Collected in Kawauchi Village after the Accident at the Fukushima Dai-ichi Nuclear Power Station.

Scientific reports

Orita M, Nakashima K, Hayashida N, Endo Y, Yamashita S, Takamura N.
PMID: 27334847
Sci Rep. 2016 Jun 23;6:28470. doi: 10.1038/srep28470.

We evaluated the current concentrations of radiocesium in local foods collected in Kawauchi Village, which is located less than 30 km from Fukushima Daiichi Nuclear Power Station, to minimize public anxiety regarding internal radiation exposure through the consumption of...

Therapeutic efficacy of bone marrow-derived mononuclear cells in diabetic polyneuropathy is impaired with aging or diabetes.

Journal of diabetes investigation

Kondo M, Kamiya H, Himeno T, Naruse K, Nakashima E, Watarai A, Shibata T, Tosaki T, Kato J, Okawa T, Hamada Y, Isobe K, Oiso Y, Nakamura J.
PMID: 25802721
J Diabetes Investig. 2015 Mar;6(2):140-9. doi: 10.1111/jdi.12272. Epub 2014 Sep 11.

AIMS/INTRODUCTION: Recent studies have shown that cell transplantation therapies, such as endothelial precursor cells, bone marrow-derived mononuclear cells (BM-MNCs) and mesenchymal stem cells, are effective on diabetic polyneuropathy through ameliorating impaired nerve blood flow in diabetic rats. Here, we...

γ-Independent through-space hetero-nuclear correlation between spin-1/2 and quadrupolar nuclei in solids.
