    Notes:
    Abstract This work describes the purification and characterization of a trypsin-like enzyme with fibrinolytic activity present in the abdomen of Haematobia irritans irritans (Diptera: Muscidae). The enzyme was purified using a one-step process, consisting of affinity chromatography on SBTI-Sepharose. The purified protease showed one major active proteinase band on reverse zymography with 0.15% gelatin, corresponding to a molecular mass of 25.5 kDa, with maximum activity at pH 9.0. The purified trypsin-like enzyme preferentially hydrolyzed synthetic substrates with arginine residue at the P1 position. The K m values determined for three different substrates were 1.88 × 10−4, 1.28 × 10−4, and 1.40 × 10−4 M for H-α-benzoyl-Ile-Glu-Gly-Arg-p-nitroanilide (S2222), dl-Ile-Pro-Arg-p-nitroanilide (S2288), and DL-Phe-Pip-Arg-p-nitroanilide (S2238), respectively. The enzyme was strongly inhibited by typical serine proteinase inhibitors such as SBTI (soybean trypsin inhibitor, K i = 0.19 nM) and BuXI (Bauhinia ungulata factor Xa inhibitor, K i = 0.48 nM), and less inhibited by LDTI (leech-derived tryptase inhibitor, K i = 1.5 nM) and its variants LDTI 2T and 5T (0.8 and 1.5 nM, respectively). The most effective inhibitor for this protease was r-aprotinin (r-BPTI) with a K i value of 39 pM. Synthetic serine protease inhibitors presented only weak inhibition, e.g., benzamidine with K i = 3.0 × 10−4 M and phenylmethylsulfonyl fluoride (PMSF) showed traces of inhibition. The purified trypsin-like enzyme also digested natural substrates such as fibrinogen and fibrin net. The protease showed higher activity against fibrinogen and fibrin than did bovine trypsin. These data suggest that the proteolytic enzyme of H. irritans irritans is more specific to proteins from blood than are the vertebrate digestive enzymes. This enzyme's characteristics may be an adaptation resulting from the feeding behavior of this hematophagous insect.

    Notes:
    We have studied the differences in the temperature dependence of exchange anisotropy of PdPtMn/CoFeB, NiFe, and NiFeTa bilayers to understand the role of ordering temperatures. The three different ferromagnetic layers [Curie temperatures: TCNiFeTa(400 °C)〈TCNiFe(570 °C)〈TCCoFeB(1040 °C)] exchange biased by the same antiferromagnet [Néel temperature: TNPdPtMn(600 °C)] showed significantly different behavior: the exchange bias field was monotonically decreasing with temperature for the CoFeB and showed distinct, broad peak for NiFe and NiFeTa at a lower temperature before it decreased above 200 °C. The temperature dependence of exchange anisotropy, calculated from the measured exchange bias field and saturation magnetization, was also different for the three bilayers as a result of the differences in Hua and MFM. The results could be understood by the modified thermal fluctuation aftereffect model, which includes the temperature dependence of the ferromagnetic magnetization and the assumption that the ordering temperature of the ferromagnetic film is different at the interface with antiferromagnet from the rest of the ferromagnetic film due to the exchange coupling with a material with high Néel temperature. © 2000 American Institute of Physics.

    A new facility using 6 MeV/n heavy-ion beams is described along with preliminary results of its applications to biophysical investigations. The beams are obtained at the terminal of the injector linac installed in the heavy-ion medical accelerator in Chiba. Various ion species (He–Xe) having different charge states are accelerated to the same velocity, which is suitable for comparing the charge effects of heavy ions. An attempt has been made for investigations of the track structure by using pBR322 plasmid DNA and spores as targets. Newly constructed equipment with the molecular beam source (H2O) placed on this beam line is also described. © 1996 American Institute of Physics.

    A new accelerator facility and two irradiation methods using 6 MeV/n heavy-ion beams are described along with preliminary results concerning their applications to biophysical investigations. The beams are obtained from the injector linac installed at the Heavy Ion Medical Accelerator in Chiba. Various ion species (He–Xe) having different charge states are accelerated to the same velocity, which is suitable for comparing the charge effects of heavy ions in the high linear energy transfer region. An attempt has been made to test the usefulness of the apparatus for studying track structure by using pBR322 plasmid DNA and spores as targets in vacuum. Newly constructed equipment with a molecular-beam source (water vapor) placed on this beam line is also described. © 1996 American Institute of Physics.

    Notes:
    The specific lattice location of Zn in CdTe single crystals has been investigated by ion-channeling methods combined with particle-induced x-ray emission. Observing the asymmetry effects of channeling dips around the [110] axis and analyzing the asymmetry factors for host atoms and doped Zn atoms, it is revealed that almost all Zn atoms occupy the Cd sublattice sites, and Zn-doped CdTe crystals grown by vertical Bridgman methods appear to be almost completely free from the segregation of doped Zn atoms.

    An extremely low-threshold current of 6 mA in cw mode at 22 °C was achieved in 1.55-μm InGaAsP/InP buried heterostructure distributed feedback lasers with a first-order grating and a normal cavity length of 300 μm. These lasers exhibited an average differential efficiency of 30% total at 4 mW without any coating on the facets, and a T0 (25–70 °C) value of 55 K. A spectral linewidth as low as 8 MHz at cw mode was obtained. The lasers showed high-speed pulse modulation response to 2.4 Gb/s (NRZ).
