We isolated four W chromosome-derived bacterial artificial chromosome (W-BAC) clones from Bombyx mori BAC libraries by the polymerase chain reaction and used them as probes for fluorescence in situ hybridization (FISH) on chromosome preparations from B.

7. Moth sex chromatin probed by comparative genomic hybridization (CGH) - Sahara, Ken; Marec, František; Eickhoff, Ulrike; Traut, Walther; ??, ?
Comparative genomic hybridization (CGH) with a probe mixture of differently labeledgenomic DNA from females and males highlighted the W chromosomes in mitotic plates and the Wchromatin in polyploid interphase nuclei of the silkworm Bombyx mori, the flour moth Ephestiakuehniella, and the wax moth Galleria mellonella.

8. In vitro cultivation of spermatocysts to matured sperm in the silkworm Bombyx mori - Kawamura, Naoko; Sahara, Ken; ??, ?
Bombyx spermatogonia are bipotential, producing nucleate eupyrene sperm and anucleate apyrene sperm.

9. TTAGG Telomeric Repeats in Chromosomes of Some Insects and Other Arthropods - Sahara, Ken; Marec, František; Traut, Walther; ??, ?
We studied the occurrence of the TTAGG telomere repeats by fluorescence in situ hybridization (FISH)and Southern hybridization in ten insect species and two other arthropods.

10. Glucose and ecdysteroid increase apyrene sperm production in in vitro cultivation of spermatocysts of Bombyx mori - Kawamura, N.; Sahara, K.; Fugo, H.; ??, ?
Two types of sperm, nucleate eupyrene and anucleate apyrene, occur in the silkworm as in other lepidopteran species.

11. Ecochemical Studies of Interrelationships between Epiphytic Bacteria and Host Plants via Secondary Metabolites - HASHIDOKO, Yasuyuki; ??, ??
In physicochemically stressed soil, rhizosphere microflora often remedy such microenvironments within the rhizosphere in order to assist in the survival of the host, and some of the microfloral compositions behave as if they were symbionts.

12. Modulation of Rat Cecal Microbiota by Administration of Raffinose and Encapsulated Bifidobacterium breve - Dinoto, Achmad; Suksomcheep, Akarat; Ishizuka, Satoshi; Kimura, Hanae; Hanada, Satoshi; Kamagata, Yoichi; Asano, Kozo; Tomita, Fusao; Yokota, Atsushi; ??, ?
To investigate the effects of administration of raffinose and encapsulated Bifidobacterium breve JCM 1192T cells on the rat cecal microbiota, in a preclinical synbiotic study groups of male WKAH/Hkm Slc rats were fed for 3 weeks with four different test diets: basal diet (group BD), basal diet supplemented with raffinose (group RAF), basal diet supplemented with encapsulated B.

13. Development and assessment of a Real-Time PCR assay for the rapid and sensitive detection of a novel thermotolerant bacterium, Lactobacillus thermotolerans, in chicken feces - Selim, Abu Sadeque Md.; Assavanig, Apinya; Sone, Teruo; Boonkumklao, Piyanuch; Wada, Masaru; Yokota, Atsushi; ??, ?
A new real-time PCR assay was successfully developed using a TaqMan fluorescence probe for specific detection and enumeration of a novel bacterium, Lactobacillus thermotolerans, in chicken feces.
