An Incidentally Detected Synthetic Fiber Embedded in the Corneal Stroma: A Report of a Rare Case

Tatsuya Mimura, Daisuke Hasegawa, Satoko Kujiraoka, Naoyuki Matsumoto

Corneal foreign bodies (CFBs) are typically caused by the penetration of external materials such as metallic particles, concrete fragments, or plant matter into the corneal tissue and are usually accompanied by intense pain or a foreign-body sensation. We report an extremely rare …

Lignocellulose molecular assembly and deconstruction properties of lignin-altered rice mutants

Andri Fadillah Martin, Yuki Tobimatsu, Pui Ying Lam, Naoyuki Matsumoto et autres

Bioengineering approaches to modify lignin content and structure in plant cell walls have shown promise for facilitating biochemical conversions of lignocellulosic biomass into valuable chemicals. Despite numerous research efforts, however, the effect of altered lignin chemistry on the supramolecular assembly of lignocellulose …

Altered lignocellulose chemical structure and molecular assembly in CINNAMYL ALCOHOL DEHYDROGENASE-deficient rice

Andri Fadillah Martin, Yuki Tobimatsu, Ryosuke Kusumi, Naoyuki Matsumoto et autres

Abstract Lignin is a complex phenylpropanoid polymer deposited in plant cell walls. Lignin has long been recognized as an important limiting factor for the polysaccharide-oriented biomass utilizations. To mitigate lignin-associated biomass recalcitrance, numerous mutants and transgenic plants that produce lignocellulose with reduced …

OsCAldOMT1 is a bifunctional O-methyltransferase involved in the biosynthesis of tricin-lignins in rice cell walls

Pui Ying Lam, Yuki Tobimatsu, Naoyuki Matsumoto, Shiro Suzuki et autres

Lignin is a phenylpropanoid polymer produced in the secondary cell walls of vascular plants. Although most eudicot and gymnosperm species generate lignins solely via polymerization of p-hydroxycinnamyl alcohols (monolignols), grasses additionally use a flavone, tricin, as a natural lignin monomer to generate …

Observation of the Tarsus Joint in the Mop-3/Bmal-1 Gene Knock-out Mouse Using ^|^ldquo;In vivo^|^rdquo; Micro-CT: Influence of Diet and Sex on Calcification of the Tendon of the Tarsus Joint

Yukiko Kai, K Matsumoto, Shigeo Kameoka, Shuuji Arai et autres

Objective of this study is to investigate whether diet or sex influences calcification of the tendon in the Mop-3/Bmal-1 gene knock-out mouse (Bmal-1 knock-out mouse) by comparing “in vivo” micro-computed tomography imaging, soft-tissue X-ray imaging, and histologic evaluation as the ‘gold standard’.23 …

Correlation between histopathological image and radiographic image pattern in fibro-osseous lesions in relation to bone complexity and distribution

Masao Araki, Shoji Kawashima, Naoyuki Matsumoto, Shun Nishimura et autres

OBJECTIVES: This study examined correlations between radiographic patterns and the shape of osteoid tissue formations, as determined histopathologically. METHODS: 20 cases of fibro-osseous lesions were investigated, comprising 5 radiographic patterns: focal (n = 3), target (n = 6), lucent (n = 4), …

Multiple cleavage sites for polymeric immunoglobulin receptor

Masatake Asano, Nobuko Takenouchi‐Ohkubo, Naoyuki Matsumoto, Yoshitaka Ogura et autres

Human polymeric immunoglobulin receptor (pIgR) was expressed in baby hamster kidney (BHK) cells using a recombinant vaccinia virus transfection system. Cleavage of pIgR on the cell surface was partially inhibited by the proteinase inhibitor, leupeptin. We addressed the question whether some particular …

Choriocarcinoma of the Mandible Developing after Odontogenic Keratocyst Excision

Naoyuki Matsumoto, Mitsuhiko Matsumoto, Takayoshi Tanaka, Hiroshi Tanaka et autres

We describe an unusual case of metastatic choriocarcinoma of the mandible. Sixteen months after odontogenic keratocyst excision, the tumor was found growing in the left molar region of the mandible, the same site of the previously enucleated odontogenic keratocyst. Histopathological examination revealed …
