Two Novel QTLs for the Harvest Index that Contribute to High-Yield Production in Rice (Oryza sativa L.).

Background: The harvest index (HI) is a measure of the biological success of forming harvestable products. However, our understanding of the genetic basis of HI in rice (Oryza sativa L.) is limited, because it is a complex trait consisting of various yield-related traits and physiological attributes.

Genetic variation of blast ( Cavara) resistance in rice ( L.) accessions widely used in Kenya.

A total of 47 rice accessions collected from Kenya were investigated the genetic variations and classified into two cluster groups, A and B, by polymorphism data of 65 simple sequence repeat (SSR) markers. Clusters A and B corresponded to Japonica and Indica Groups, respectively. The number of Japonica Group accessions was limited in comparison with those of the Indica Group.

Genetic variation in resistance to blast ( Cavara) in rice ( L.) germplasms of Bangladesh.

Genetic variation in blast resistance was clarified in 334 Bangladesh rice accessions from 4 major ecotypes (Aus, Aman, Boro and Jhum). Cluster analysis of polymorphism data of 74 SSR markers separated these accessions into cluster I (corresponding to the Japonica Group) and cluster II (corresponding to the Indica Group). Cluster II accessions were represented with high frequency in all ecotypes.

Genetic variation of root angle distribution in rice ( L.) seedlings.

We developed a new method of using seedling trays to evaluate root angle distribution in rice (. L), and found a wide genetic variation among cultivars. The seedling tray method can be used to evaluate in detail the growth angles of rice crown roots at the seedling stage by allocating nine scores (10° to 90°).

Identification of a low tiller gene from a new plant type cultivar in rice ( L.).

We characterized a rice introgression line, YTH34, harboring a chromosome segment from a New Plant Type (NPT) cultivar, IR65600-87-2-2-3, in the genetic background of an Indica Group elite rice cultivar, IR 64, under upland and irrigated lowland conditions in Japan. The number of panicles (as an indicator of tiller number) and number of spikelets per panicle of YTH34 were lower than those of IR 64 under irrigated lowland conditions, but both of those as well as culm length, panicle length, seed fertility, panicle weight, whole plant weight, and harvest index were dramatically reduced under upland conditions. And the low tiller of YTH34 was confirmed to start after the maximum tiller stage.

[A Case of Cardiac Arrest following Intra-articular Administration of Levobupivacaine during Total Knee Arthroplasty].

A 73-year-old woman with normal cardiac function underwent an elective total knee arthroplasty. After skin closure, levobupivacaine 225 mg was injected into the knee and 25 mg was injected subcutaneously. The patient recovered from general anesthesia 5 min after the surgery.

[Postoperative Analgesia in Peritonectomy for Patients with Peritoneal Surface Malignancy].

Background: We investigated the efficacy of postoperative analgesia in peritonectomy for patients with peritoneal surface malignancy, by comparing peripheral nerve block (PNB) with intravenous patient controlled analgesia (iv-PCA) group to patient controlled epidural analgesia (PCEA) group.

Methods: Forty one patients of PNB+iv-PCA group received ultrasound guided rectus sheath block (using 0.25% levobupivacaine 20 ml bilaterally) and posterior transversus abdominis plane block (30 ml bilaterally) after induction of anesthesia.

[Influence of remifentanil on postoperative pain with intravenous patient-controlled analgesia following total knee arthroplasty].

Background: There is a controversy about the development of acute opioid tolerance during remifentanil infusion for postoperative pain. We investigated whether intraoperative remifentanil infusion leads to rapid development of tolerance. We also investigated whether adjuvant analgesic is effective or not.

[Blood transfusion therapy for massive hemorrhage associated with scheduled peritonectomy for pseudomyxoma peritonei and peritoneal dissemination].

Background: The component therapy has been recommended for surgical hemorrhage. We investigated whether the component therapy was useful for surgical patients undergoing the scheduled peritonectomy for pseudomyxoma peritonei or peritoneal dissemination.

Methods: Twenty patients were divided into two groups (the component therapy for 7 patients and the early transfusion of flesh frozen plasma therapy for 13 patients).
