Abstract
PCR-RFLP based on the translation elongation factor 1α (TEF) gene was developed to identify Fusarium fujikuroi in the Fusarium (Gibberella) fujikuroi species complex. Ninety-three strains, most of which were obtained from various sources in Japan, were identified as F. fujikuroi and their capability to produce fumonisin was investigated using an in vitro assay. Fumonisin production was detected in 50 strains isolated from maize, strawberry, wheat, and rice, whereas it was undetectable in 43 strains derived from rice seeds and rice seedlings carrying the bakanae disease, and from unknown sources. A single nucleotide polymorphism in the TEF gene (T618G) correlated with the ability to synthesize fumonisin.

Abstract
Fusarium oxysporum f. sp. fragariae is a fungal pathogen causing Fusarium wilt on strawberry. Polymerase chain reaction (PCR) primers that can discriminate F. oxysporum f. sp. fragariae from nonpathogenic F. oxysporum would greatly assist pathogen identification. In order to develop a molecular diagnostic tool for this pathogen, transposable elements in the pathogen were characterized and used for designing a specific set of PCR primers. Portions of the transposable elements Fot3, Han, Hop, Hornet1, and Skippy were detected in all 33 strains of F. oxysporum f. sp. fragariae tested by PCR, whereas Foxy was detected in 32 strains and Impala sequences were detected in 30 strains. Two types of sequences were detected for Hop, two types for Impala, and three types for Skippy. The genomic region between Han and Skippy was amplified by an inter-retrotransposon amplified polymorphism technique, and PCR primers (FofraF and FofraR) to specifically identify F. oxysporum f. sp. fragariae were designed from this region. The developed PCR primers discriminated F. oxysporum f. sp. fragariae strains from nonpathogenic F. oxysporum strains and five other formae speciales. Conidia of F. oxysporum f. sp. fragariae could be detected in brown lowland-type soil by PCR using the primers. After preculturing the soil sample on FoG2 medium, 1 × 102 conidia/g of soil could be detected; without preculturing, 1 × 103 conidia/g of soil were detected.

Abstract
In this letter, we advocate recognizing the genus Fusarium as the sole name for a group that includes virtually all Fusarium species of importance in plant pathology, mycotoxicology, medicine, and basic research. This phylogenetically guided circumscription will free scientists from any obligation to use other genus names, including teleomorphs, for species nested within this clade, and preserve the application of the name Fusarium in the way it has been used for almost a century. Due to recent changes in the International Code of Nomenclature for algae, fungi, and plants, this is an urgent matter that requires community attention. The alternative is to break the longstanding concept of Fusarium into nine or more genera, and remove important taxa such as those in the F. solani species complex from the genus, a move we believe is unnecessary. Here we present taxonomic and nomenclatural proposals that will preserve established research connections and facilitate communication within and between research communities, and at the same time support strong scientific principles and good taxonomic practice.

Abstract
Phytophthora nicotianae and P. cactorum cause Phytophthora rot of strawberry. A duplex real-time PCR technique for simultaneous detection and quantification of the two pathogens was developed. Species-specific primers for P. nicotianae and P. cactorum were designed based on the internal transcribed spacer regions (ITS) of rDNA and the ras-related protein gene Ypt1, respectively. TaqMan probes were labeled with FAM for P. nicotianae and HEX for P. cactorum. Specificities were demonstrated using 52 isolates, including various soil-borne pathogens. Sensitivities for P. nicotianae and P. cactorum DNAs were 10 fg and 1 pg, respectively. The technique was applied to naturally infested soil and root samples; the two pathogens were detected and the target DNA concentrations were quantified. Significant correlations of DNA quantities in roots and the surrounding soils were found. The minimum soil DNA concentration predicting the development of disease symptoms was estimated as 20 pg (g soil)(-1). In three strawberry greenhouses examined, the target DNA concentrations ranged from 1 to 1,655 pg (g soil)(-1) for P. nicotianae and from 13 to 233 pg (g soil)(-1) for P. cactorum. The method proved fast and reliable, and provides a useful tool to monitor P. nicotianae and P. cactorum in plants or soils.

Abstract
Dust seeds that germinate by obtaining nutrients from symbiotic fungi have evolved independently in orchids and 11 other plant lineages. The fungi involved in this 'mycoheterotrophic' germination have been identified in some orchids and non-photosynthetic Ericaceae, and proved identical to mycorrhizal fungi of adult plants. We investigated a third lineage, the Pyroleae, chlorophyllous Ericaceae species whose partial mycoheterotrophy at adulthood has recently attracted much attention. We observed experimental Pyrola asarifolia germination at four Japanese sites and investigated the germination pattern and symbiotic fungi, which we compared to mycorrhizal fungi of adult plants. Adult P. asarifolia, like other Pyroleae, associated with diverse fungal species that were a subset of those mycorrhizal on surrounding trees. Conversely, seedlings specifically associated with a lineage of Sebacinales clade B (endophytic Basidiomycetes) revealed an intriguing evolutionary convergence with orchids, some of which also germinate with Sebacinales clade B. Congruently, seedlings clustered spatially together, but not with adults. This unexpected transition in specificity and ecology of partners could support the developmental transition from full to partial mycoheterotrophy, but probably challenges survival and distribution during development. We discuss the physiological and ecological traits that predisposed to the repeated recruitment of Sebacinales clade B for dust seed germination.

Abstract
OBJECTIVES The purpose of this study was to evaluate the optimal upper threshold levels of a number of individuals and determine the most suitable upper threshold. METHODS A phantom model and ten patients were used in this study. The phantom was made of acrylic resin and urethane resin and had nine pillar-shaped air spaces. The subjects were ten female patients with jaw deformities who were not affected by respiratory disease. The optimal threshold levels were determined using the "calculation of CT value disparities" (CCTD) technique, which we devised. In other words, the mean CT values along two lines (air space and soft tissue) were calculated and the optimal threshold level was determined as the level that produced the maximum difference between the CT values measured inside and outside of the air-space border. RESULTS The optimal upper threshold levels of the nine phantom holes calculated using the CCTD technique in the front-on standing position and side-on standing position were -434 HU and -456 HU, respectively. The optimal upper threshold level of the ten patients calculated using the CCTD technique was -472 HU. The true threshold level of each patient was defined as the optimal threshold level calculated using the CCTD technique. The mean threshold level was defined as -472 HU. The absolute differences between the volume measurements obtained with these two measures were considered. Therefore, the no error values were -460 HU and -470 HU. CONCLUSIONS We consider that the most suitable upper threshold level for extracting the airway is from -460 HU to -470 HU.

Abstract
AIMS Using the HbA(1c) level to define diabetes has several advantages and these advantages also apply to define a high-risk group. However, the risk of diabetes increases as HbA(1c) increases and a certain degree of arbitrariness in the cut-off for the high risk group is unavoidable. The aim of this study was to determine the HbA(1c) cut-off for defining a high-risk group that corresponds to the fasting plasma glucose cut-off by comparing the risk of diabetes against the fasting plasma glucose and HbA(1c) levels in the Japanese population. METHODS A retrospective cohort study was conducted using data from annual health examinations performed in Omiya city. A total of 11,271 subjects between the ages of 40 and 79 years without diabetes at baseline were followed for up to 7 years. According to the new diagnostic criteria, diabetes was defined as an fasting plasma glucose level ≥ 7 mmol/l or an HbA(1c) level ≥ 48 mmol/mol (≥ 6.5%) or a self-report. The HbA(1c) cut-off corresponding to the fasting plasma glucose cut-off was determined using the incidence, hazard ratio, and a receiver operating characteristic analysis. RESULTS Eight hundred and sixty subjects developed diabetes. The incidence, hazard ratio, and receiver operating characteristic analysis all indicated that an HbA(1c) cut-off of 39 mmol/mol (5.7%) corresponded to an fasting plasma glucose level of 5.6 mmol/l. CONCLUSIONS Our results suggested that the HbA(1c) cut-off for high-risk of diabetes should be 39 mmol/mol (5.7%), consistent with the American Diabetes Association recommendation. Further research is needed to determine whether our results are applicable to other populations.

Abstract
BACKGROUND CC chemokine ligand (CCL) 18 is expressed by monocytes and dendritic cells (DCs), and has potent chemotactic activity for T cells, B cells and DCs. CCL18 expression is up-regulated in lesional skin of atopic dermatitis and bullous pemphigoid, suggesting its important roles in the development of these skin diseases. OBJECTIVE To investigate roles of CCL18 in cutaneous T-cell lymphoma (CTCL). METHODS The CCL18 messenger RNA (mRNA) expression in CTCL skin (n = 21) and in normal skin (n = 7) was examined by quantitative RT-PCR. CCL18 expression was also examined by immunohistochemistry. Serum CCL18 levels were measured in 38 patients with CTCL and 20 healthy controls by enzyme-linked immunosorbent assay. We also analysed correlation between serum CCL18 levels and other clinical and laboratory data. RESULTS The CTCL lesional skin contained higher levels of CCL18 mRNA than normal skin. CCL18 was expressed by dermal macrophages and DCs in CTCL skin. Serum CCL18 levels in patients with CTCL were significantly higher than those of healthy controls and correlated with types of skin lesions. They also significantly correlated with modified severity-weighted assessment scores, serum sIL-2R, LDH, IL-4, IL-10, IL-31, CCL17 and CCL26 levels. Patients with high serum levels of CCL18 showed significantly poor prognosis compared with those with low CCL18 levels. CONCLUSION CCL18 mRNA is up-regulated in CTCL lesional skin, and serum CCL18 levels are significantly increased and correlated with the severity of CTCL. These results suggest that CCL18 may be associated with the development of CTCL.

Abstract
AIMS To investigate the effects of the combined application of an N-acyl homoserine lactone (HSL) analog and antibiotics on biofilms of Porphyromonas gingivalis, a major pathogen of periodontal disease. METHODS AND RESULTS Antibiotics used were cefuroxime, ofloxacin and minocycline. A flow-cell model was used for biofilm formation. Samples were divided into four groups: control, analog-treated, antibiotic-treated and combined application groups. Biofilm cell survival was determined using adenosine triphosphate (ATP) bioluminescence and confocal laser microscopy (CLSM). In the combined application group, the ATP count in biofilm cells was significantly decreased compared with the antibiotic-treated group (Games-Howell test, P < 0·05). A combination of cefuroxime and the analog was most effective against the P. gingivalis biofilm. CLSM observations revealed that the proportion of dead cells was highest in the combined application group. CONCLUSIONS The combined application of the N-acyl HSL analog and antibiotics was effective at reducing the viability of P. gingivalis cells in biofilms. SIGNIFICANCE AND IMPACT OF THE STUDY The combined application of the N-acyl HSL analog and antibiotics may be successful for eradicating infections involving bacterial biofilms, such as periodontitis.

Abstract
We aimed to simultaneously detect two pathogens causing strawberry diseases, Phytophthora nicotianae and P. cactorum, by multiplex polymerase chain reaction (PCR), and to survey their occurrence in the main strawberry production areas of Japan. Due to the need to combine different primer pairs for multiplex PCR and the low specificity of published specific primers for P. nicotianae and P. cactorum, new species-specific primers for P. nicotianae and P. cactorum were designed based on the internal transcribed spacer regions of ribosomal DNA and the ras-related protein gene Ypt1, respectively. Specificity of the designed primers was demonstrated using 68 isolates, including Phytophthora spp., Pythium spp., and other soilborne pathogens. Multiplex PCR discriminated between P. nicotianae and P. cactorum in DNA mixtures of mycelia of the two species. Moreover, both species were detected in artificially and naturally infested soils, indicating that these markers can be used in diagnosis of strawberry diseases. For investigation of the geographic distribution of the two pathogens in Japan, soil samples were collected in 89 strawberry fields from eight prefectures (Gifu, Saga, Nara, Tochigi, Chiba, Shizuoka, Yamanashi, and Hokkaido) of Japan. The method that was developed was successfully applied to survey P. nicotianae and P. cactorum, and distribution of the two pathogens in strawberry plantings in Japan was determined.
