Pigment-Dispersing Factor Is Involved in Age-Dependent Rhythm Changes in Drosophila melanogaster
- Y. Umezaki, T. Yoshii, T. Kawaguchi, C. Helfrich-Förster, K. Tomioka
- Biology, Medicine
- Journal of biological rhythms
- 1 December 2012
Most animals show rest/activity rhythms that are regulated by an endogenous timing mechanism, the so-called circadian system. The rhythm becomes weaker with age, but the mechanism underlying the… Expand
Sexual Interactions Influence the Molecular Oscillations in DN1 Pacemaker Neurons in Drosophila melanogaster
- Shiho Hanafusa, T. Kawaguchi, Y. Umezaki, K. Tomioka, T. Yoshii
- Biology, Medicine
- PloS one
- 18 December 2013
Circadian rhythms can synchronize to environmental time cues, such as light, temperature, humidity, and food availability. Previous studies have suggested that these rhythms can also be entrained by… Expand
Distribution of prolylhydroxyproline and its metabolites after oral administration in rats.
- T. Kawaguchi, P. N. Nanbu, M. Kurokawa

- Biological & pharmaceutical bulletin
- 1 March 2012
Prolylhydroxyproline (Pro-Hyp), which is derived from collagen hydrolysate, has been shown to be beneficial for skin and joint health. However, little is known about the distribution of Pro-Hyp in… Expand
Caenorhabditis elegans Responses to Specific Steroid Hormones
- N. Tominaga, K. Ura, +5 authors K. Arizono
- Biology
- 1 February 2003
In this paper, Caenorhabditis elegans (C. elegans) is proposed as a model organism for studying chemical effects over multiple generations. We investigated whether C. elegans responds to vertebrate… Expand

We investigate the gravitational and electromagnetic fields on the generalized Lagrange space endowed with the metricgij(x, y) = γij(x) + {1 + 1/n2(x, y)}yiyj. The generalized Lagrange spacesMm do… Expand
Characterization of Linear Poly(N-isopropylacrylamide) and Cloud Points in its Aqueous Solutions
- K. Kobayashi, S. Yamada, Kouta Nagaoka, T. Kawaguchi, Masashi Osa, Takenao Yoshizaki
- Chemistry
- 15 May 2009
The second virial coefficient A2 and intrinsic viscosity [η] were determined in methanol at 25.0 °C for poly(N-isopropylacrylamide) (PNIPA) samples synthesized by living anionic polymerization in the… Expand
Cloud Points in Aqueous Poly(N-isopropylacrylamide) Solutions
- T. Kawaguchi, Y. Kojima, Masashi Osa, Takenao Yoshizaki
- Chemistry
- 15 May 2008
The cloud point was determined for aqueous solutions of four kinds of poly(N-isopropylacrylamide) samples synthesized by radical polymerization in methanol, tert-butanol, benzene, and 1,4-dioxane by… Expand
