Nine Different Glucose-6-phosphate Dehydrogenase (G6PD) Variants in a Malaysian Population with Malay, Chinese, Indian and Orang Asli (Aboriginal Malaysian) Backgrounds (2008)

Wang, Jichun, Luo, Enjie, Hirai, Makoto, Arai, Meiji, Isa, Zaleha Mohamed, ...

The Malaysian people consist of several ethnic groups including the Malay, the Chinese, the Indian and the Orang Asli (aboriginal Malaysians). We collected blood samples from outpatients of 2...

Seven Different Glucose-6-phosphate Dehydrogenase Variants Including a New Variant Distributed in Lam Dong Province in Southern Vietnam. (2007)

Matsuoka, Hiroyuki, Thuan, Dang Thi Vinh, Van Thien, Huynh, Kanbe, Toshio, Jalloh, Amadu, Hirai, Makoto, ...

We conducted a survey for glucose-6-phosphate dehydrogenase (G6PD) deficiency using blood samples from male outpatients of a local hospital in southern Vietnam. Most of the samples were from the Kinh...

Anti-malarial activity of leaf-extract of hydrangea macrophylla, a common Japanese plant. (2006)

Kamei, Kiseko, Matsuoka, Hiroyuki, Furuhata, Syun-ichi, Fujisaki, Ryu-ichi, Kawakami, Tomotaka, Mogi, Seiji, ...

To find a new anti-malarial medicine derived from natural resources, we examined the leaves of 13 common Japanese plants in vitro. Among them, a leaf-extract of Hydrangea macrophylla, a common...

Estimation of the sporozoite rate of malaria vectors using the polymerase chain reaction and a mathematical model. (2006)

Harada, Masakazu, Ishikawa, Hirofumi, Matsuoka, Hiroyuki, Ishii, Akira, Suguri, Setsuo

We developed a sensitive polymerase chain reaction (PCR) method for the detection of Plasmodium falciparum DNA from mosquitoes collected in the field. Plasmodium falciparum was detected from 15.2% of...

Effects of Mating on Oogenesis Induced by Amino Acid Infusion, Amino Acid Feeding, or Blood Feeding in the Mosquito Anopheles stephensi (Diptera: Culicidae) (2003)

Keikichi Uchida, Atsuko Moribayashi, Hiroyuki Matsuoka, Tsutomu Oda

Hemocoel infusion of an amino acid mixture at a concentration of 7.5% and 10% (wt:vol) for 24 h rarely activated ovarian development in either mated or unmated females of Anopheles stephensi Liston....

Induction of Oogenesis in Mosquitoes (Diptera: Culicidae) by Infusion of the Hemocoel with Amino Acids (2001)

Keikichi Uchida, Tsutomu Oda, Hiroyuki Matsuoka, Atsuko Moribayashi, Daijiro Ohmori, Yuki Eshita, ...

As done previously with adult females of Culex pipiens pallens Coquillett, a mixture of 17 amino acids was infused into the hemocoel of females of seven anautogenous and one autogenous mosquito...

Sequence Diversity and Linkage Disequilibrium within the Merozoite Surface Protein-1 (Msp-1) Locus of Plasmodium falciparum: A Longitudinal Study in Brazil (2001)

WEBER L. RIBEIRO, KARIN KIRCHGATTER, GERHARD WUNDERLICH, HIROYUKI MATSUOKA, KAZUYUKI TANABE, ...

The merozoite surface protein-1 (MSP-1) is a major vaccine candidate for the asexual blood stage of malaria. We examined both the extent of sequence diversity in block 17, the 3′ end of Msp-1 gene...

Sequence Variation in the T-Cell Epitopes of the Plasmodium falciparum Circumsporozoite Protein among Field Isolates Is Temporally Stable: a 5-Year Longitudinal Study in Southern Vietnam

Jalloh, Amadu, Van Thien, Huynh, Ferreira, Marcelo U., Ohashi, Jun, Matsuoka, Hiroyuki, Kanbe, Toshio, ...

In an effort to decipher the nature and extent of antigen polymorphisms of malaria parasites in a setting where malaria is hypomesoendemic, we conducted a 5-year longitudinal study (1998 to 2003) by...
