Devices made from stretchable electronic materials could be incorporated into clothing or
attached directly to the body. Such materials have typically been prepared by engineering …

Bilirubin, the end product of heme catabolism in mammals, is generally regarded as a
potentially cytotoxic, lipid-soluble waste product that needs to be excreted. However, it is shown …

… Yukiya Yamamoto, Yukiya Yamamoto … We also thank Dr Kazuhito Yamamoto for technical
advice and Ms Yoko Kudo and Ms Yoko Tagawa for secretarial and technical assistance. …

Single-photon sources have recently been demonstrated using a variety of devices, including
molecules 1 , 2 , 3 , mesoscopic quantum wells 4 , colour centres 5 , trapped ions 6 and …

We describe a four-state atomic system that absorbs two photons, but does not absorb one
photon. As a switch, in the ideal limit, it operates at an energy cost of one photon per …

The discovery of the enhancement of Raman scattering by molecules adsorbed on nanostructured
metal surfaces is a landmark in the history of spectroscopic and analytical techniques. …

NF-κB in defense and disease ing lymphocyte activation (8). The chemotherapeutic agent
etoposide also increases NF-κB levels and thereby induces A1/Bfl-1, which prevents …

… The cyclization of alkenes, allenes, and alkynes bearing Y−Z at an appropriate position of
the carbon chain (section 4) is classified under category 2. The two processes, C−C and C …

To estimate the minimal gene set required to sustain bacterial life in nutritious conditions, we
carried out a systematic inactivation of Bacillus subtilis genes. Among ≈4,100 genes of the …

The present study was conducted to evaluate the validity and reproducibility of noninvasive
brachial-ankle pulse wave velocity (baPWV) measurements and to examine the alteration of …
