Rotational resonance for a heteronuclear spin pair under magic-angle spinning in solid-state NMR.

The Journal of chemical physics

Kamihara T, Takegoshi K.
PMID: 28433023
J Chem Phys. 2017 Apr 21;146(15):154202. doi: 10.1063/1.4980156.

Rotational resonance (R2) is one of the widely applied techniques in solid-state NMR for recoupling a homonuclear dipolar interaction under magic-angle spinning (MAS). R2 occurs as the result of interference between the difference of the chemical shifts and MAS....

Aneurysm growth after late conversion of thoracic endovascular aortic repair.

SAGE open medical case reports

Kasahara H, Hayashi I, Haijima N.
PMID: 27489673
SAGE Open Med Case Rep. 2015 Jan 08;3:2050313X14565422. doi: 10.1177/2050313X14565422. eCollection 2015.

A 69-year-old man underwent thoracic endovascular aortic repair of a descending aortic aneurysm. Three years later, he developed impending rupture due to aneurysmal expansion that included the proximal landing zone. Urgent open surgery was performed via lateral thoracotomy, and...

Genetic association between G protein-coupled receptor kinase 6/β-arrestin 2 and dopamine supersensitivity psychosis in schizophrenia.

Neuropsychiatric disease and treatment

Oda Y, Kanahara N, Kimura H, Watanabe H, Hashimoto K, Iyo M.
PMID: 26251601
Neuropsychiatr Dis Treat. 2015 Jul 29;11:1845-51. doi: 10.2147/NDT.S86042. eCollection 2015.

BACKGROUND/AIM: Dopamine supersensitivity psychosis (DSP), clinically characterized by unstable and severe psychosis or tardive dyskinesia and often categorized as treatment-resistant schizophrenia, is promoted by long-term antipsychotic treatment. An upregulation of the dopamine D2 receptor caused by antipsychotic(s) is involved...

Heterozygous Polg mutation causes motor dysfunction due to mtDNA deletions.

Annals of clinical and translational neurology

Fuke S, Kametani M, Yamada K, Kasahara T, Kubota-Sakashita M, Kujoth GC, Prolla TA, Hitoshi S, Kato T.
PMID: 25540805
Ann Clin Transl Neurol. 2014 Nov;1(11):909-20. doi: 10.1002/acn3.133. Epub 2014 Oct 22.

OBJECTIVE: Mutations in nuclear-encoded mitochondrial DNA (mtDNA) polymerase (POLG) are known to cause autosomal dominant chronic progressive external ophthalmoplegia (adCPEO) with accumulation of multiple mtDNA deletions in muscles. However, no animal model with a heterozygous Polg mutation representing mtDNA...

Arylation of diorganochalcogen compounds with diaryliodonium triflates: metal catalysts are unnecessary.

Organic letters

Racicot L, Kasahara T, Ciufolini MA.
PMID: 25493925
Org Lett. 2014 Dec 19;16(24):6382-5. doi: 10.1021/ol503177q. Epub 2014 Dec 10.

Diaryliodonium triflates transfer an aryl group to the chalcogen atom of organic sulfides, selenides, and tellurides (but not ethers), in the absence of transition-metal catalyst, simply upon heating in chloroform or dichloroethane solution.

Ciliochoroidal Detachment Following Scleral Buckling Surgery for Rhegmatogenous Retinal Detachment.

Japanese journal of ophthalmology

Kawahara S, Nagai Y, Kawakami E, Ida RY, Takeuchi M, Uyama M.
PMID: 11094196
Jpn J Ophthalmol. 2000 Nov 01;44(6):692-693. doi: 10.1016/s0021-5155(00)00255-0.

Purpose and Methods: We observed the peripheral choroid, ciliary body, and depth of the anterior chamber by ultrasound biomicroscopy (UBM) in 31 eyes with rhegmatogenous retinal detachment before and after scleral buckling surgery. Scleral encircling was performed in 11...

Hepatitis C virus (HCV) genotype 1b sequences from fifteen patients with hepatocellular carcinoma: the 'progression score' revisited.

Hepatology research : the official journal of the Japan Society of Hepatology

Takahashi K, Iwata K, Matsumoto M, Matsumoto H, Nakao K, Hatahara T, Ohta Y, Kanai K, Maruo H, Baba K, Hijikata M, Mishiro S.
PMID: 11348851
Hepatol Res. 2001 Jun;20(2):161-171. doi: 10.1016/s1386-6346(00)00141-8.

The genome of hepatitis C virus (HCV) associated with hepatocellular carcinoma (HCC) may have some characteristics which would barely be found in those of HCV from asymptomatic carriers (ASC). We analyzed 15 HCC patients who were infected with HCV...

Double-chelation-assisted Rh-catalyzed intermolecular hydroacylation.

Organic letters

[reaction: see text] Rh-Catalyzed intermolecular hydroacylation between salicylaldehydes and 1,5-hexadienes proceeded under remarkably mild reaction conditions to afford a mixture of iso- and normal-hydroacylated products in good yields. The experiments using deuterated salicylaldehyde-d revealed that "double chelation" of salicylaldehyde...

First Isolation and Characterization of Sodium and Potassium Tellurocarboxylates: Structural Analysis of Te-Alkyl Telluroester.
