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...

BACKGROUND: An extraordinary hermaphrodite of dioecious willows provides us an opportunity to examine the inheritance of sex expression and the magnitude of inbreeding depression using a progeny assay of the hermaphrodite.RESULTS: We indentified 165 progeny of an open-pollinated hermaphrodite...

PhytoKeys. 2016 Jun 15;(65):47-55. doi: 10.3897/phytokeys.65.6726. eCollection 2016.

A new species of Hamamelidaceae, Eustigma honbaense H.Toyama, Tagane & V.S.Dang, sp. nov., is described from Hon Ba Nature Reserve, Vietnam. This species is similar to Eustigma oblongifolium Gardner & Champ., but differs from it in having entire leaves,...

The Neurocognitive Basis for Impaired Dual-Task Performance in Senior Fallers.

Frontiers in aging neuroscience

Nagamatsu LS, Hsu CL, Voss MW, Chan A, Bolandzadeh N, Handy TC, Graf P, Beattie BL, Liu-Ambrose T.
PMID: 26903862
Front Aging Neurosci. 2016 Feb 09;8:20. doi: 10.3389/fnagi.2016.00020. eCollection 2016.

Falls are a major health-care concern, and while dual-task performance is widely recognized as being impaired in those at-risk for falls, the underlying neurocognitive mechanisms remain unknown. A better understanding of the underlying mechanisms could lead to the refinement...

Hydrocortisone enhances the barrier properties of HBMEC/ciβ, a brain microvascular endothelial cell line, through mesenchymal-to-endothelial transition-like effects.

Fluids and barriers of the CNS

Furihata T, Kawamatsu S, Ito R, Saito K, Suzuki S, Kishida S, Saito Y, Kamiichi A, Chiba K.
PMID: 25763180
Fluids Barriers CNS. 2015 Mar 05;12:7. doi: 10.1186/s12987-015-0003-0. eCollection 2015.

BACKGROUND: Because in vitro blood-brain barrier (BBB) models are important tools for studying brain diseases and drug development, we recently established a new line of conditionally immortalized human brain microvascular endothelial cells (HBMEC/ciβ) for use in such models. Since...

Pattern stability and trijunction motion in eutectic solidification.

Physical review. E, Statistical, nonlinear, and soft matter physics

Akamatsu S, Plapp M, Faivre G, Karma A.
PMID: 12366091
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Sep;66(3):030501. doi: 10.1103/PhysRevE.66.030501. Epub 2002 Sep 03.

We demonstrate by both experiments and phase-field simulations that lamellar eutectic growth can be stable for a wide range of spacings below the point of minimum undercooling at low velocity, contrary to what is predicted by existing stability analyses....

Isolation of an inclusion complex of naphthol and its benzoate as an intermediate in the solvent-free benzoylation reaction of naphthol.

Organic & biomolecular chemistry
