A spontaneous non-pathogenic variant (Cong:1-2) derived from Fusarium oxysporum f. sp. conglutinans (Cong: 1-1), a causal agent of cabbage yellows, carries biocontrol activity for cabbage yellows. We found a GMC oxidoreductase (ODX1) among the proteins expressed much more in Cong:1-2 than Cong:1-1 by 2D-DIGE comparison. GMC oxidoreductases have been(More)
Recent empirical studies reveal that effectiveness of aid on growth is ambiguous. This paper considers aid proliferation-excess aid investment relative to recurrent cost-as a potential cause that undermines aid effectiveness, because aid projects can only produce sustainable benefits when sufficient recurrent costs are disbursed. We consider the donor's(More)
Plants in clusters are often more productive than those located in non-clusters. This has been explained by agglomeration effects that improve productivity of all plants in a region. However, recent theoretical development of trade and spatial economic theories with heterogeneous firms has shed light on another channel of productivity improvement in(More)
Diphtheria-tetanus-acellular pertussis vaccine (DTaP) developed in Japan is now widely used worldwide. DTaP is safer than the diphtheria-tetanus-whole-cell pertussis vaccine (DTwP) and has fewer severe side effects, but local reactions such as redness, swelling, and induration are still reported. The pathophysiological mechanism of these reactions is(More)
We performed two courses of interferon-beta (IFN-beta) to a child with chronic hepatitis C. A complete response was not obtained by the first interferon treatment, however, the results of the second treatment differed from those of the first. Hepatitis C virus (HCV)-RNA remained negative and both aspartate aminotransferase and alanine aminotransferase(More)
We encountered a case which proved to be a mixed infection of herpes simplex virus (HSV) type 1 and type 2 in retrospective terms by in situ hybridization (ISH) and polymerase chain reaction (PCR). The case was a male. The gestational age was 39 weeks and 2 days. The birth body weight was 3024 g. A fever developed from the age of 6 days and he was admitted(More)
The lasing performance of single-cavity and double-cavity Tm, Ho:YLF lasers was measured experimentally. The maximum, single-longitudinal mode output power for the double-cavity laser was 30 mW, whereas for the single-cavity laser it was 7 mW. We determined the frequency stabilities to be 600 Hz for a single-cavity laser and 300 Hz for a double-cavity(More)
We report a familial clustering case of hepatitis delta. All of the members of this family had evidence of past infection of hepatitis B. We investigated the hepatitis delta, three of the members had positive serological hepatitis delta markers. We assayed by polymerase chain reaction the primers corresponding to hepatitis delta antigen. The results of(More)
Anti varicella-zoster virus (VZV) antibodies were detected by an immune adherence hemagglutination (IAHA) test, and were compared with the CF test, IFA test and ELISA test, respectively. Type O, Rh-positive RBC for IAHA was obtained from five healthy volunteers. All five RBCs had sufficient sensitivity as the indicator cell. Optimum incubation temperature(More)
In 1995 an investigation was made for VP4 regions of coxsackie virus A16 (CA16) RNA sequence from hand-foot-mouth disease patients in eastern district of Shizuoka Prefecture. Subjects were seven patients who were diagnosed as hand-foot-mouth disease due to CA16 at the Ohashi Pediatric Clinic in Susono City. Throat swabs of patients were extracted to RNA.(More)
