    Notes: SiO2 thin films prepared by rapid thermal oxidation (RTO) and in situ steam generation (ISSG) were characterized by infrared spectroscopy (IR) with gradient etching preparation and grazing incidence x-ray reflectometry. The IR spectra of the RTO films show a lower wave number shift as the film thickness decreases. On the other hand, the IR spectra of the ISSG film produced by the addition of 5% hydrogen did not show such large peak shifts. This means that the 5% hydrogen ISSG film has a very low concentration of lower wave number components that exhibit Si–O stretching mode. These are responsible for defect structures including dangling bonds and/or oxygen deficient defects near the SiO2/Si interface. © 2002 American Institute of Physics.

    Notes: : Hydroperoxides and n-hexanal of soymilk made at different temperatures in the soybean grinding process were investigated. Both hydroperoxides and n-hexanal showed maximum amounts at 30°C, 37.78 μmol/g, and 1.94 mg/g, respectively. However, at 3°C and 80°C, amounts of hydroperoxides were about half of that at 30°C. N-hexanal showed high correlation with hydroperoxides except for at 80°C. It suggests that controlling the grinding temperature is effective to reduce hydroperoxidation and off-flavor content. Protein solubility an important index of soymilk, was decreased as the temperature increased. Grinding soybeans at low temperature is considered an economical method to produce soymilk having less off-flavor and high protein.

    Notes: Forty patients with solar urticaria, 16 male and 24 female, were examined personally during the past 25 years. The median age at onset of symptoms was 32 years, ranging from 13 to 76 years. Most commonly (45%) solar urticaria first appeared during the third decade. The mean duration of the disease was 3·6 years at presentation. The action spectrum was found in the visible light range in 24 patients (60%), in the ultraviolet (UV) A range in four, in the UVB in four, from the UVA to UVB in three, from the UVA to visible light in one and in a broad range from UVB to visible light in four patients. An inhibition spectrum was detected in 13 of 19 patients (68%), occurring at longer wavelengths than the action spectrum in 12 of these cases. The augmentation spectrum was found in only four of 14 patients (29%) examined. Twenty-four of 31 patients (77%) developed an urticarial reaction to autologous serum, which had been previously irradiated in vitro at the action spectrum for that patient. In a single patient, solar urticaria was caused by a drug, namely chlorpromazine. In two patients, polymorphic light eruption occurred in association with solar urticaria. No single modality of treatment was satisfactory, but combined use of antihistamines, sunbathing, psoralen UVA photochemotherapy and/or sunscreening agents partially suppressed the symptoms.

    Notes: The rockmover wrasse Novaculichthys taeniourus was observed using coral fragments for mound construction on the reefs of Kuchierabu-jima Island, Japan. The wrasse heaped between four and 71 pieces of coral fragments on each sand mound, and dived into the mound just before sunset. Coral fragments may facilitate the retention of sleeping sites under competition with other sand-diving wrasses.

    Intra-abdominal synovial sarcoma: a clinicopathological study (2004)

    Notes: Aims : To evaluate a series of synovial sarcomas arising in the abdomen, pelvic cavity, or retroperitoneum. Synovial sarcoma is rare within the abdomen. In this location, it can be confused with other biphasic tumours and with other spindle and round cell sarcomas.Methods and results : Cases were retrieved from archives. There were 11 intra-abdominal tumours among 300 synovial sarcomas in two referral practices (3.7%). Three were pelvic (two midline, one sidewall) and eight were retroperitoneal. They occurred in six males and five females aged from 25 to 75 years (mean 49 years, median 46 years), and ranged in diameter from 65 to 470 mm (mean 210 mm, median 150 mm). Six examples were biphasic, five were monophasic and seven had poorly differentiated areas. Monophasic tumours displayed at least one epithelial marker. One biphasic tumour had a SYT-SSX2 fusion gene. Seven sarcomas were high-grade and four of intermediate grade malignancy. Follow-up data were available in 10 patients. In all but one case, tumour recurred or metastasized within the abdomen. The pelvic sarcomas also metastasized outside the abdomen. Eight of 10 patients (80%) died of disease with survival from 4 to 36 months (mean 17 months, median 18 months). Two patients were alive with disease at 43 and 48 months.Conclusions : Synovial sarcomas rarely arise within the abdomen and pelvis. They occur mainly in middle age, attain a large size, are difficult to excise and recur locally. Pelvic tumours metastasize distantly. Retroperitoneal tumours remain confined to the abdomen and, unlike synovial sarcomas elsewhere, do not metastasize remotely, although mortality is high.

    Notes: Primary rhabdoid tumour of the lung is rare, and histological and biological characteristics have not been fully documented. We describe three cases of primary lung rhabdoid tumour, all associated with adenocarcinoma, and investigate the histological features and biological characteristics.〈section xml:id="abs1-2"〉〈title type="main"〉Methods and resultsThree cases were obtained from a total 902 cases of surgically removed primary lung tumours between 1986 and 1998. The rhabdoid cells were found to occupy about 50–90% of each tumour. All of the tumours had nonrhabdoid adenocarcinoma foci in the centre of the tumours. Transition between the adenocarcinomatous and rhabdoid components was demonstrated. Detailed immunohistochemical studies were carried out. The epithelial markers, cytokeratins and epithelial membrane antigen (EMA), were strongly expressed in rhabdoid and adenocarcinomatous components. Furthermore, surfactant apoprotein A was positive in both components in one case, but myoglobin, MyoD and HHF35 were not expressed. Vimentin was strongly and diffusely stained in all cases. The neuroendocrine markers, chromogranin A (all cases), neuron-specific antigen (NSE) (two cases) and CD56 (one case) were occasionally positive in only a small number of the rhabdoid tumour cells. GM-CSF was positively stained in one case, and the dedifferentiated characteristics of the rhabdoid cells was suggested. Proliferative cell nuclear antigen (PCNA) was strongly demonstrated in the rhabdoid tumour cells (all cases). To gain better understanding the highly proliferative characteristics of the tumours, p53 gene (exons 5–8) mutation was examined by DNA sequencing analysis; mutation of the p53 DNA was not detected. Overexpression of p53 protein was also not demonstrated in all cases. HPV6 was demonstrated in one case by PCR method and also non-isotopic in-situ hybridization (NISH). Two cases died in a short period of time (3 years and 4 months, respectively).〈section xml:id="abs1-3"〉〈title type="main"〉ConclusionThe rhabdoid cells in these three cases were considered to represent the dedifferentiated components of the accompanying adenocarcinoma. Dedifferentiated characteristics (neuroendocrine markers, GM-CSF, vimentin, and the aggressive behaviour) were evident.

    Notes: Abstract  Activating missense mutations in the Arg 201 codon of the gene encoding the α subunit of Gs, the G protein that stimulates cAMP formation, have been recognized as the cause of many endocrine diseases, McCune-Albright syndrome and isolated fibrous dysplasia of bone. On the other hand, intramuscular myxomas with fibrous dysplasia, so-called Mazabraud’s syndrome, have been sporadically reported, but it has not been confirmed whether intramuscular myxoma, with or without fibrous dysplasia, is associated with the Gsα mutations. We investigated the presence of the Gsα mutations in intramuscular myxomas with or without fibrous dysplasia by a PCR-SSCP assay, using formalin-fixed, paraffin-embedded tissues. In five of the six intramuscular myxomas (three with and two without fibrous dysplasia), point mutations were detected as aberrant bands by SSCP, which were confirmed by a subsequent sequence analysis (three Arg to His and two Arg to Cys). This result suggests that the Gsα mutations are related to tumorigenesis in intramuscular myxoma and that intramuscular myxoma is one of the diseases induced by abnormal Gsα protein.

    Notes: Abstract  We report a case of chordoma containing a spindle cell sarcomatoid component with a gradual transition from conventional chordoma. Immunohistochemically, many tumor cells in both conventional chordoma and sarcomatoid components were positive for cytokeratins (AE1/AE3, CAM5.2) and epithelial membrane antigen as well as vimentin. This report provides a rare example of sarcomatoid chordoma. Familiarity with this type of bone tumor should help to avoid confusion with dedifferentiated chordoma and other spindle cell sarcomas or carcinomas.
