The human fungal pathogen Candida albicans is able to change its shape in response to various environmental signals. We analyzed the C. albicans BIG1 homolog, which might be involved in β-1,6-glucan...

Mutation rate and novel tt mutants of Arabidopsis thaliana induced by carbon ions.

Shikazono, Naoya, Yokota, Yukihiko, Kitamura, Satoshi, Suzuki, Chihiro, Watanabe, Hiroshi, Tano, Shigemitsu, ...

Irradiation of Arabidopsis thaliana by carbon ions was carried out to investigate the mutational effect of ion particles in higher plants. Frequencies of embryonic lethals and chlorophyll-deficient...

Elimination of atretic follicles from the mouse ovary: a TEM and immunohistochemical study in mice

INOUE, SATOKO, WATANABE, HIROSHI, SAITO, HIDEKAZU, HIROI, MASAHIKO, TONOSAKI, AKIRA

We examined numerous ovarian follicles from 32–35 d virgin mice by transmission electron microscopy and light microscopic immunohistochemistry. No macrophages were seen, but various stages of...

Relationship between NaF- and thapsigargin-induced endothelium-dependent hyperpolarization in rat mesenteric artery

Fukao, Mitsuhiro, Hattori, Yuichi, Sato, Atsushi, Liu, Ming-Yue, Watanabe, Hiroshi, Kim, Tran Quang, ...

In isolated rat mesenteric artery with endothelium, NaF caused slowly developing hyperpolarization. The hyperpolarizing effect was unchanged in the presence of NG-nitro-L-arginine (L-NOARG) and...

Antimicrobial Susceptibility and Genetic Characteristics of Streptococcus pneumoniae Isolates Indicating Possible Nosocomial Transmission Routes in a Community Hospital in Japan▿

Qin, Liang, Masaki, Hironori, Watanabe, Kiwao, Furumoto, Akitsugu, Watanabe, Hiroshi

A clinical study was designed to study Streptococcus pneumoniae isolates recovered from a community hospital in Japan from April 2001 to November 2002. A total of 73 isolates were defined as derived...

Regulation of anaphylactic responses by phosphatidylinositol phosphate kinase type I α

Sasaki, Junko, Sasaki, Takehiko, Yamazaki, Masakazu, Matsuoka, Kunie, Taya, Choji, Shitara, Hiroshi, ...

The membrane phospholipid phosphatidylinositol 4, 5-bisphosphate [PI(4,5)P2] is a critical signal transducer in eukaryotic cells. However, the physiological roles of the type I phosphatidylinositol...

Sodium channel β1 subunit mutations associated with Brugada syndrome and cardiac conduction disease in humans

Watanabe, Hiroshi, Koopmann, Tamara T., Le Scouarnec, Solena, Yang, Tao, Ingram, Christiana R., Schott, Jean-Jacques, ...

Brugada syndrome is a genetic disease associated with sudden cardiac death that is characterized by ventricular fibrillation and right precordial ST segment elevation on ECG. Loss-of-function...

Distributivity for a Monad and a Comonad

John Power, Hiroshi Watanabe

We give a systematic treatment of distributivity for a monad and a comonad as arises in incorporating category theoretic accounts of operational and denotational semantics, and in giving an...

Transport of LDL-derived cholesterol from the NPC1 compartment to the ER involves the trans-Golgi network and the SNARE protein complex

Urano, Yasuomi, Watanabe, Hiroshi, Murphy, Stephanie R., Shibuya, Yohei, Geng, Yong, Peden, Andrew A., ...

Mammalian cells acquire cholesterol mainly from LDL. LDL enter the endosomes, allowing cholesteryl esters to be hydrolyzed by acid lipase. The hydrolyzed cholesterol (LDL-CHOL) enters the...

Wnt/β-Catenin and noncanonical Wnt signaling interact in tissue evagination in the simple eumetazoan Hydra

Philipp, Isabelle, Aufschnaiter, Roland, Özbek, Suat, Pontasch, Stefanie, Jenewein, Marcell, Watanabe, Hiroshi, ...

In and evaginations of 2D cell sheets are major shape generating processes in animal development. They result from directed movement and intercalation of polarized cells associated with cell shape...
