Monosomic lines of Nicotiana tabacum are helpful to confirm the location of genes on specific chromosomes. In the cross N. nudicaulis and N. tabacum, hybrid seedlings express lethal symptoms, which are controlled by the S subgenome of N. tabacum. to identify the responsible chromosome, we needed to produce chromosome lacking lines (CLLs) of N. tabacum L. “Red Russian” and use them to cross with N. nudicaulis. From a cross of (N. tabacum × N. tomentosiformis) × N. tabacum, 380 BC1 individuals were obtained. Using a Haplo-Q line (a monosomic line lacking the single linkage group 11) and N. tabacum, we found that qPCR is a simple and reliable screening method for CLLs of N. tabacum. the marker Pt30342 is located on linkage group 11, and the -Ct value (Ct Actin - Ct Pt30342) was 2.0 for a disomic line and was 1.097 for a Haplo-Q line. By the use of flow cytometry, qPCR and chromosome counting together as a screening method, we identified 6 CLLs lacking 2 to 6 chromosomes. Compared with conventional methods, our method is a rapid technique for making and screening CLLs ofthe S or S/t subgenome of N. tabacum. Further, these CLLs will be useful to identify the location of two or more factors on chromosomes controlling a variety of genetic problems affecting breeding. Here, we only made CLLs of the S or S/t subgenome of N. tabacum. We will use the method established in this study to produce CLLs of the t subgenome of N. tabacum, and gather a full set of CLLs of N. tabacum. qPCR could also be applied to the identification of chromosome aberrations in other plants.

the aim of this study is to clarify factors related to premature death among Japanese professional baseball players by a case-control analysis. the subjects are two matching groups of 622 Japan Professional Baseball (JPB) league players, those deceased and those surviving. Cases and controls are matched by birth year. All players debuted on the first string between 1934 and 2003, and are listed in the Official Baseball Encyclopedia of Japan. to compare means and frequencies of characteristics between deceased and surviving groups, t-tests and chi-square tests were used. A logistic regression analysis was assessed contributions of each independent variable on death. Significant differences between deceased and surviving players were observed in this study;deceased players had higher body mass indexes and longer careers. Furthermore, logistic regression analysis confirmed that body mass index and career length were statistically significant determinants of death for baseball players. this is the first report to examine factors of death for professional baseball players except employing data attained from Major League Baseball.

假膜性结肠炎与过敏性紫癜的关系

世界核心医学期刊文摘（胃肠病学分册） 2005年第11期1卷 57-58页

A 79- year-old man was admitted because of cholecystitis that occurred about 40 days after sigmoidectomy had been performed for colonic cancer. though antibiotics improved his condition, the patient had hematochezia,diarrhea, and left lower abdominal pain. Colonoscopic findings showed multiple ring-like areas of redness and petechiae in the rectosigmoid colon and marked edema from the descending to the transverse colon. the patient then developed purpura on the extensor surfaces of the legs and bilateral gonalgia, and exacerbation of the hematochezia. A second colonos-copy (CS) showed multiple ring-like areas of redness and ecchymosis throughout the colon. the patient was diagnosed with Henoch-Sch nlein purpura (HSP), and the symptoms were attenuated after the administration of prednisolone. However, diarrhea recurred in about a week; stool culture confirmed Clostridium difficile, and a third CS revealed pseudomembranes throughout the colon. the patient was diagnosed with pseudomembranous colitis (PMC), and the administration of vancomycin attenuated the symptoms. In conclusion, we have reported a rare adult case of PMC that occurred during prednisolone treatment for HSP. the PMC may have been caused by changes in the intestinal bacterial flora after the sigmoidectomy and by the intestinal lesions of HSP, as well as by the administration of antibiotics after the sigmoidectomy and for the treatment of cholecystitis, and by the use of prednisolone for the treatment of the HSP.

在X射线暴高温高密度的环境中,18Ne(α,p)21Na很可能是由热CNO循环突破到rp过程的一个重要反应。到目前为止,人们测得的反应率还存在很大的不确定性。实验中用CRIB(CNS Radioactive Ion Beam separator)提供的21Na放射性束轰击8.8 mg/cm2的聚乙烯厚靶,利用放置在θlab=-14°,0°,14°处的3套硅条探测器望远镜阵列对反冲轻粒子进行鉴别和测量,测得在一段能区(Ex=5.5～9.2MeV)内21Na(p,p)21Na的激发函数。通过对21Na(p,p)共振弹性散射截面进行R矩阵拟合,得到了22Mg共振能级的自旋宇称以及质子宽度等信息,从而为计算18Ne(α,p)21Na反应率提供了实验参数。

the paper includes discussions on the important role of neutron and alpha configurations in proton-rich nuclei in nuclear astrophysics in terms of nucleosynthesis under extremely high-temperature hydrogenburning conditions. the νp-process, which is supposed to take place at the very early epoch of type II supernovae, has considerable neutrons and alphas together with protons. the alpha-induced reactions on proton-rich unstable nuclei in the light mass regions is expected to play a crucial role, but very few of them were investigated well yet because of the experimental difficulties. Specifically, I report our recent experimental effort for the breakout process from the pp-chain region,~7Be(α, γ)^(11)C(α,p)^(14)N under the νp-process. the neutron-induced reactions on proton-rich nuclei, which is even more a challenging subject, were investigated previously for very few nuclei. One possible experimental method is the trojan Horse Method(tHM). We successfully have applied tHM to the ^(18)F(n,α)^(14)N reaction study with an unstable beam of ^(18)F.

在核素图上,Z～56、N～80区域被认为是检验核结构理论。如 IBM 模型、壳模型等的理想区域另外,本区域也是磁转动(shears band)存在的候选核区之一。有别于形变核的电集体转动和一般球形核的单粒子激发,磁转动是一种产生高自旋态的新机制,已引起实验、理论两方面的兴浓厚地和关注。由于该区域的核很难用标准布居高自旋态的方法—融合蒸发反应和自发裂变产生,高激发态,特别是高自旋态数据很少,深部非弹反应可以产生稳定线附近的丰中子核,我们提出了利用深部非弹反应研究该区核激发的态实验建议。为了检验其可行性,先进行了探索性实验。

Osteosarcomas are primary malignant tumors that are characterized by the production of osteoid or immature bone. However they are the most common primary malignant tumor of bone in adolescents and young adults, the diagnosis of osteosarcoma is often delayed. It is because of the rarity of population, the variety of findings, nonspecific symptoms and so on. A 46-year-old male patient had left knee pain for 3 months without any symptoms in his right knee. At a nearby clinic, X-ray of his healthy side was taken by chance. the irregular bone formation was however seen in the metaphysis of the distal femur with spreading into the soft tissues. No abnormal findings were pointed out at his left side knee. A diagnosis of pleomorphic sarcoma was made by incisional biopsy. Pulmonary Ct showed multiple nodules which were considered as multiple lung metastases. He was diagnosed as right femoral sarcoma, clinical stage IV (t1N0M1a) by tNM classification. He underwent preoperative chemotherapy, followed by limb-saving operation. No preoperative complaints were found in his left knee. Final diagnosis of surgically resected specimen was osteoblastic osteosarcoma which showed neoplastic osteoid formation within pleomorphic malignant cells. However, osteosarcomas occurred in adult populations are sometimes occurred as a secondary neoplasms, he had a history of diabetes but no other medical history, such as radiation therapy for a solid cancer, Paget’s disease, other benign bone lesions or inherited conditions. As far as our knowledge, we believe that this is a first case report of asymptomatic incidental osteosarcoma.
