High Mitochondrial Genome Diversity and Intricate Population Structure of in Kyushu, Japan.

Mitogenomic diversity and genetic population structure of the pinewood nematode (PWN) Bursaphelenchus xylophilus inhabiting Kyushu, Japan were analyzed. A method for performing long PCR using single nematodes and sequencing nematode mitochondrial genomes individually is presented here. About 8 kb (∼55%) of the complete mitochondrial genome was successfully obtained from 285 individuals collected from 12 populations.

[A case of small intestinal GIST maintained as a long stable disease by imatinib mesylate 400 mg/day, alternate-day administration for 2 weeks followed by a 2 week interval].

Unlabelled: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. The recent molecular-targeted therapies (imatinib and sunitinib) have improved the treatment of GIST remarkably. However, it would be ideal if the amount of these drugs could be adjusted according to each patient because they have various side effects and are very expensive.

Isolation and characterization of tetranucleotide microsatellite loci in Pinus massoniana (Pinaceae).

Premise Of The Study: Tetranucleotide microsatellite markers were developed for the first time in Pinus massoniana Lamb. to facilitate studies of population and conservation biology in this species.

Methods And Results: Ten tetranucleotide microsatellite primer pairs were developed using dual suppression PCR.

Improved AFLP protocol using dual-suppression PCR and its application to species with large genomes.

To improve the amplified fragment length polymorphism assay, dual-suppression PCR was introduced into the preamplification step of the assay. The dual-suppression PCR blocked completely the amplification of fragments with the same sequence (Bsp1407I-Bsp1407I or NlaIII-NlaIII) at both ends and amplified selectively fragments with different adaptor sequences (Bsp1407I-NlaIII) at each end. Two protocols, referred to as A and B, were established for species with medium- and large-sized genomes, respectively.

Ribosomal DNA haplotype distribution of Bursaphelenchus xylophilus in Kyushu and Okinawa islands, Japan.

Ribosomal DNA region sequences (partial 18S, 28S and complete ITS1, 5.8S, and ITS2) of the pinewood nematode (Bursaphelenchus xylophilus) were obtained from DNA extracted directly from wood pieces collected from wilted pine trees throughout the Kyushu and Okinawa islands, Japan. Either a 2569bp or 2573bp sequence was obtained from 88 of 143 samples.

[A case of severe hand-foot syndrome caused by capecitabine].

A 55-year-old woman underwent total mastectomy and axillary lymphnode dissection in 2001. Widespread lymphnode metastasis was found histologically (26/33). Neither PgR nor ER was positive.

[Method of levofolinate.5-FU administration by hepatic arterial infusion therapy for hepatic metastasis from colorectal cancer].

Hepatic arterial infusion chemotherapy with levofolinate (l-leucovorin) and fluorouracil regimen was performed using an implanted port system on unresectable hepatic metastasis patients with colorectal cancer. A comparative study was performed on two groups in which the levofolinate was administered arterially or intravenously. Levofolinate 200-250 mg/m(2) was infused for two hours intra-arterially or intravenously, and 5-FU 400-600 mg/m(2) was administered as a bolus in midinfusion.

Prognostic factors and scoring system for survival in colonic perforation.

Background/aims: No ideal and generally accepted prognostic factors and scoring systems exist to determine the prognosis of peritonitis associated with colonic perforation. This study was designed to investigate prognostic factors and evaluate the various scoring systems to allow identification of high-risk patients.

Methodology: Between 1996 and 2003, excluding iatrogenic and trauma cases, 26 consecutive patients underwent emergency operations for colorectal perforation and were selected for this retrospective study.

Sequence characterized amplified region markers tightly linked to the mating factors of Lentinula edodes.

Detecting the mating types in shiitake, Lentinula edodes (Berk.) Pegler, is important for making progress in the breeding of this mushroom and determining the compatibility of the pair to cross. Shiitake is a tetrapolar fungus with two unlinking mating factors, A factor and B factor.
