Divergence insufficiency associated with high myopia.

Clinical ophthalmology (Auckland, N.Z.)

Kohmoto H, Inoue K, Wakakura M.
PMID: 21311651
Clin Ophthalmol. 2010 Dec 22;5:11-6. doi: 10.2147/OPTH.S14759.

PURPOSE: Divergence insufficiency is generally regarded as a neurological event. While high myopia is not a well-known cause of divergence insufficiency, we frequently encounter divergence insufficiency in high-myopia patients. Thus, the purpose of this study was to report detailed...

Indium-Catalyzed [2 + 2] Cycloaddition of Allylsilanes to Internal Alkynones.

Organic letters

Okamoto K, Shimbayashi T, Tamura E, Ohe K.
PMID: 26584237
Org Lett. 2015 Dec 04;17(23):5843-5. doi: 10.1021/acs.orglett.5b03065. Epub 2015 Nov 19.

We have developed an indium-catalyzed [2 + 2] cycloaddition of allylsilanes to alkynones leading to selective cyclobutenone formation. The resulting cyclobutenones were readily converted to the oxidized products by Tamao-Fleming oxidation or the ring-opened products by an electrocyclic reaction.

Radical-polar crossover reactions of vinylboron ate complexes.

Science (New York, N.Y.)

Kischkewitz M, Okamoto K, Mück-Lichtenfeld C, Studer A.
PMID: 28254937
Science. 2017 Mar 03;355(6328):936-938. doi: 10.1126/science.aal3803.

Vinyl boronic esters are valuable substrates for Suzuki-Miyaura cross-coupling reactions. However, boron-substituted alkenes have drawn little attention as radical acceptors, and the radical chemistry of vinylboron ate complexes is underexplored. We show here that carbon radicals add efficiently to...

Large Parosteal Lipoma without Periosteal Changes.

Plastic and reconstructive surgery. Global open

Aoki S, Kiyosawa T, Nakayama E, Inada C, Takabayashi Y, Sumi Y, Doumoto T, Aizawa T, Azuma R.
PMID: 25674368
Plast Reconstr Surg Glob Open. 2015 Feb 06;3(1):e287. doi: 10.1097/GOX.0000000000000254. eCollection 2015 Jan.

Parosteal lipoma is a rare tumor, accounting for approximately 0.3% of all lipomas. Bony lesions are often found in patients with this tumor (59.2%), making the differential diagnosis of malignant tumors important. Our case was a 64-year-old male patient...

Endoscopy-Guided Evaluation of Duodenal Mucosal Permeability in Functional Dyspepsia.

Clinical and translational gastroenterology

Ishigami H, Matsumura T, Kasamatsu S, Hamanaka S, Taida T, Okimoto K, Saito K, Minemura S, Maruoka D, Nakagawa T, Katsuno T, Fujie M, Arai M.
PMID: 28383567
Clin Transl Gastroenterol. 2017 Apr 06;8(4):e83. doi: 10.1038/ctg.2017.12.

OBJECTIVES: The pathophysiology of functional dyspepsia (FD) is not fully understood. Impaired duodenal mucosal integrity characterized by increased mucosal permeability and/or low-grade inflammation was reported as potentially important etiologies. We aimed to determine the utility of a recently developed...

On the effects of substitution, intercalation, non-stoichiometry and block layer concept in TiS2 based thermoelectrics.

Physical chemistry chemical physics : PCCP

Guilmeau E, Maignan A, Wan C, Koumoto K.
PMID: 26343362
Phys Chem Chem Phys. 2015 Oct 14;17(38):24541-55. doi: 10.1039/c5cp01795e.

TiS2 based layered sulfides have recently received increasing interest from the thermoelectric community. Due to its layered structure, the TiS2 compound with its enormous capacity for chemical substitution and intercalation offers different means to optimize the thermoelectric response through...

Hypomagnesemia during pediatric orthotopic liver transplantation.

Journal of anesthesia

Sato T, Okamoto K, Ogata K, Kurose M, Sadanaga M, Board J.
PMID: 28921196
J Anesth. 1994 Mar;8(1):36-39. doi: 10.1007/BF02482751.

We evaluated the incidence and severity of serum magnesium (Mg) abnormality along with other electrolyte and acid-base disturbances before and during the course of orthotopic liver transplantation (OLT) in pediatric patients. Serum Mg, Na, K, ionized Ca, pH, and...

Proposal for new diagnostic criteria for DIC from the Japanese Society on Thrombosis and Hemostasis.

Thrombosis journal

Disseminated intravascular coagulation (DIC) is a serious disease that, in the presence of underlying disease, causes persistent, generalized, marked coagulation activation. Early treatment based on an appropriate diagnosis is very important for improving patients' prognosis, to which end diagnostic...

Dielectric Mismatch Mediates Carrier Mobility in Organic-Intercalated Layered TiS2.

Nano letters

The dielectric constant is a key parameter that determines both optical and electronic properties of materials. It is desirable to tune electronic properties though dielectric engineering approach. Here, we present a systematic approach to tune carrier mobilities of hybrid...

Triphenylphosphine ligand-protected Au9 clusters deposited onto titania nanosheets show three different atomic configurations as observed by scanning transmission electron microscopy. The configurations observed are a 3-dimensional structure, corresponding to the previously proposed Au9 core of the clusters, and two...
