Jin RB, Takeoka M, Takagi U, Shimizu R, Sasaki M.
PMID: 25791212
Sci Rep. 2015 Mar 20;5:9333. doi: 10.1038/srep09333.

Entanglement swapping at telecom wavelengths is at the heart of quantum networking in optical fiber infrastructures. Although entanglement swapping has been demonstrated experimentally so far using various types of entangled photon sources both in near-infrared and telecom wavelength regions,...

OBJECTIVE: To investigate the efficacy of multioverlapping therapy using a polysaccharide nanosheet having 75-nm thickness for sealing and stopping massive venous hemorrhage.METHODS: The hydrostatic durability of the polysaccharide nanosheet was evaluated in vitro when secured to an incised silicon...

Thermally Tunable Hydrogels Displaying Angle-Independent Structural Colors.

Angewandte Chemie (International ed. in English)

Ohtsuka Y, Seki T, Takeoka Y.
PMID: 26503915
Angew Chem Int Ed Engl. 2015 Dec 14;54(51):15368-73. doi: 10.1002/anie.201507503. Epub 2015 Oct 27.

We report the preparation of thermally tunable hydrogels displaying angle-independent structural colors. The porous structures were formed with short-range order using colloidal amorphous array templates and a small amount of carbon black (CB). The resultant porous hydrogels prepared using...

Pancreatectomy and splenectomy for a splenic aneurysm associated with segmental arterial mediolysis.

World journal of gastrointestinal surgery

Matsuda Y, Sakamoto K, Nishino E, Kataoka N, Yamaguchi T, Tomita M, Kazi A, Shinozaki M, Makimoto S.
PMID: 26015853
World J Gastrointest Surg. 2015 May 27;7(5):78-81. doi: 10.4240/wjgs.v7.i5.78.

Segmental arterial mediolysis (SAM) is characterized by intra-abdominal, retroperitoneal bleeding or bowel ischemia, and the etiology is unknown. A 44-year-old man complaining of abdominal pain was admitted to our hospital. He had been admitted for a left renal infarction...

Recurrent syncope in two patients with a sigmoid-shaped interventricular septum and no left ventricular hypertrophy.

Journal of arrhythmia

We report a wavelength division multiplexed time-bin entangled photon pair source in telecom wavelength using a 10 μm radius Si ring resonator. This compact resonator has two add ports and two drop ports. By pumping one add port by...

Noble-gas-rich chondrules in an enstatite meteorite.

Nature

PMID: 11518959
Nature. 2001 Aug 23;412(6849):795-8. doi: 10.1038/35090520.

Chondrules are silicate spherules that are found in abundance in the most primitive class of meteorites, the chondrites. Chondrules are believed to have formed by rapid cooling of silicate melt early in the history of the Solar System, and...

A highly cis-selective synthesis of 2-ethynylaziridines by intramolecular amination of chiral bromoallenes: improvement of stereoselectivity based on the computational investigation.

Journal of the American Chemical Society

Ohno H, Ando K, Hamaguchi H, Takeoka Y, Tanaka T.
PMID: 12487601
J Am Chem Soc. 2002 Dec 25;124(51):15255-66. doi: 10.1021/ja0262277.

The base-mediated intramolecular amination of bromoallenes having an axial chirality is described. The treatment of (4S,aR)-4-alkyl-4-[N-(arylsulfonyl)amino]-1-bromobuta-1,2-dienes with NaH in DMF affords 2,3-cis-2-ethynylaziridines in good to excellent selectivity (2,3-cis:trans = 92:8-99:1). The reaction of (4S,aS)-bromoallenes with NaH/DMF also gives 2,3-cis-2-ethynylaziridines...
