    Notes: Abstract. Background: Although a specific syndrome of the uterus didelphys, obstructive hemivagina, and ipsilateral renal agenesis had been reported in gynecologic literatures, it is not familiar to radiologists. We introduce this syndrome with radiological, especially MR findings. Methods: Imaging findings and medical records of seven patients with this syndrome were retrospectively reviewed. Results: MR clearly demonstrated uterus didelphys with obstructed hemivagina in six of the seven patients. A remaining one showed uterus didelphys with left-sided hematometra and hematosalpinx who had undergone vaginal septum incision prior to the MR. We could also recognize ipsilateral renal agenesis in all five patients, in whom renal areas were examined on MR. After vaginal septum resection, symptoms disappeared in six patients. We could observe the disappearance of the obstructive complications with MR in three patients. Conclusions: MR can do much for the early diagnosis and the prevention against further complications of this condition because it can demonstrate the müllerian duct anomaly complicated with obstructed hemivagina in detail and even ipsilateral renal agenesis.

    Notes: Abstract Angiomyolipoma is a benign mesenchymal tumor that has been reported frequently in the kidney but rarely in the liver. In the present study, we present four cases of hepatic angiomyolipoma with different radiologic appearances, discuss differential diagnosis, and review previously reported cases. One of our cases was followed for 8 years. Computed tomography (plain, enhanced, and dynamic study), magnetic resonance imaging (T1-weighted spin echo, T2-weighted spin echo, and dynamic study), ultrasonography, and angiography were performed in all cases. Although different radiologic appearances were observed in the tumors, based on different proportions of fat, blood vessels, and muscle, three cases were diagnosed as angiomyolipoma. In one case, it was quite difficult to make radiologic diagnosis; hepatocellular carcinoma with fatty metamorphosis in part was most likely suspected, but histopathological examination revealed angiomyolipoma with few fat elements. In the present study, early and prolonged enhancement of the lesion with the special pattern of time density/intensity curve was significant for angiomyolipoma, and we suggest that preoperative radiologic diagnosis of the lesion is possible in most of the cases. However, it can be quite difficult to distinguish angiomyolipoma from some hepatocellular carcinomas with fatty metamorphosis.

    Phylogenetic relationships among species of Calyptogena (Bivalvia: Vesicomyidae) collected around Japan revealed by nucleotide sequences of mitochondrial genes (1995)

    Notes: Abstract Phylogenetic relationships among the seven species of deep-sea giant clams Calyptogena (Bivalvia: Vesicomyidae) collected around Japan were examined using parts of nucleotide sequences of mitochondrial genes for cytochrome oxidase I (COI) and cytochrome oxidase III (COIII) and the encoded amino acid sequences. The seven species were C. soyoae (Sagami Bay), C. fausta (Suruga Bay), C. kaikoi (Nankai Trough), C. nautilei (Nankai Trough), C. phaseoliformis (Japan Trench), C. solidissima (Minami-Ensei Knoll, Okinawa Trough) and Calyptogena sp. (Iheya Ridge, Okinawa Trough). A clear phylogenetic split was observed between one group of three species (C. kaikoi, C. phaseoliformis and C. fausta) and the remaining species. This clustering corresponds to the two previously described subgenera within the genus Calyptogena (Calyptogean and Ectenagena) with the exception of the placement of C. nautilei, which had been placed in the subgenus Ectenagena. Genetic distances between two haplotypes of C. soyoae were 0.043 for the COI region and 0.055 for the COIII region, and three amino acid substitutions were detected with the COIII region. Calyptogena sp. from the Iheya Ridge could be distinguished from one of the two haplotypes (type A) of C. soyoae by only a single nucleotide substitution, a result that suggests that Calyptogena sp. of the Iheya Ridge diverged from C. soyoae after the two haplotypes had diverged, and it is now isolated from C. soyoae in Sagami Bay.

    Genetic relationships of pilchards (genus: Sardinops) with anti-tropical distributions (1996)

    Notes: Abstract The pilchards (genus Sardinops), one of the major components of the world's harvest of fishes, is distributed sporadically in the temperate zone on a global scale. Mitochondrial DNA variation in 95 pilchards from nine worldwide localities in five current systems was examined using ten restriction enzymes. Although several opinions have been proposed on the global population structure of the genus Sardinops, our results clearly rejected the hypothesis of gene flow among geographically distant populations on a global scale. Results indicate that the Japanese pilchards and the Australian and South African pilchards were derived from the eastern Pacific populations, following the speciation of Sardinops in the Pacific, after the formation of the Isthmus of Panama. An intermixing of the northeastern and southeastern Pacific populations during the Pleistocene glacial maxima is suggested from their genetic affinities.

    Notes: Abstract Objective: To evaluate the role of surfactant in the mechanism and treatment of acute lung injury caused by inhalation of fabric protector. Design: Prospective, randomized study. Setting: University laboratory. Interventions: In vitro experiment: a porcine surfactant suspension (10 mg · ml−1) was exposed to a fabric protector aerosolized with an ultrasonic nebulizer for 1 min. Minimum surface tension (γ min) was sequentially measured using pulsating bubble equipment. Animal experiment: 14 adult rats were anesthetized with pentobarbital and mechanically ventilated with pure oxygen. Then, all rats inhaled fabric protector aerosolized with the nebulizer for five breaths. Three hours after inhalation, the rats were randomly assigned to two groups: a surfactant group (n = 7), in which surfactant (100 mg · kg−1) was replaced, and a control group (n = 7), in which no substance was given. Measurements and results: In vitro experiment: exposure to fabric protector aerosol increased the mean γ min of the surfactant from 1.7 to 19.2 mN · m−1 (n = 5, p 〈 0.05). Animal experiment: the mean partial pressure of oxygen in arterial blood (PaO2) in all rats decreased from 62.8 to 17.1 kPa at 3 h after inhalation. The PaO2 in the surfactant group increased to 49.8 ± 11.1 (SD) kPa at 30 min after surfactant replacement (p 〈 0.05), while the PaO2 in the control group remained below 20 kPa. Conclusions: Impairment of surfactant is a factor involved in the development of acute lung injury caused by inhalation of fabric protector. Surfactant replacement may be therapeutic for such injuries.

    Notes: Abstract. In this study, the pulsed laser ablation of RuO2 and SrRuO3 (SRO) is investigated by observing the fluorescence from excited atoms in the plume by using a framing streak camera. Vaporization, phase explosion and boiling are suggested to play the main roles in the processes for the interaction between the laser beam and target. Collisions and adiabatic expansion are also suggested before particles move forward with shifted Maxwellian spatial distribution. In O2 pressure, numerous collisions between fast and slow atoms occur and result in the exchange of speeds. The structural and electrical (conductivity and work-function) properties of RuO2 and SRO thin films are measured. Epitaxial SRO growth was obtained at growth temperatures down to 350 °C. Ferroelectric and high- dielectric thin-film capacitors with RuO2 or SRO thin film electrode are also studied.

    Structure of a new alkaline serine protease (M-protease) from Bacillus sp. KSM-K16 (1995)

    Notes: An alkaline serine protease, M-protease, from Bacillus sp. KSM-K16 has been crystallized. Two morphologically different crystal forms were obtained. Crystal data of form 1: space group P212121, a = 47.3, b = 62.5, c = 75.6 Å, V = 2.23 × 105 Å3, Z = 4 and Vm = 2.09 Å3 Da−1. Crystal data of form 2: space group P212121, a = 75.82 (2), b = 57.79 (2), c = 54.19 (1) Å, V = 2.29 (2) × 105 Å3, Z = 4 and Vm = 2.15 Å3 Da−1. The crystal structure of M-protease in form 2 has been solved by molecular replacement using the atomic model of subtilisin Carlsberg (SBC) which is 60% homologous with M-protease, and refined to the crystallographic R-factor of 0.189 for 7004 reflections with Fo/σ(F) 〉 3 between 7 and 2.4 Å resolution. The final model of M-protease contains 1882 protein atoms, two calcium ions and 44 water molecules. The three-dimensional structure of M-protease is essentially similar to other subtilisins of known structure. The 269 Cα positions of M-protease have an r.m.s. difference of 1.06 Å with the corresponding positions of SBC. The crystal data of form 2 are close to those of SBC, though the structure determination of form 2 made it clear that it is not isomorphous to the crystal structure of SBC. The deletions of amino acids occur at the residues 36′ and 160′–163′ compared with SBC (numerals with primes show the numbering for SBC). The deletion of the four residues (160′–163′) may significantly affect the lack of isomorphism between M-protease and SBC.
