Probing molecular bond-length using molecular-frame photoelectron angular distributions.

The molecular-frame photoelectron angular distributions (MFPADs) in O 1s photoemission from CO molecule were measured. Patterns due to photoelectron diffractions were observed in the MFPADs. The polarization-averaged MFPADs were compared with theoretical calculation and were found to be useful in determining the molecular bond-length, which is a component to determine molecular structures.

Formation of hot hydrogen atoms from superexcited states of acetylene.

The cross sections for the formation of the H(2) and H(2) atoms, and , respectively, in photoexcitation of CH were obtained in an absolute scale for studying formation and decay of superexcited states in the extreme ultraviolet range. Several superexcited states of CH including multiply excited states were found in the curve of the cross sections as a function of the incident photon energy. The same states seem to contribute to the variation in the cross sections as well, which can be ascribed to the non-adiabatic transitions between the 2 and 2 channels.

Identification of sialyl oligosaccharides including an oligosaccharide nucleotide in colostrum of an addax (Addax nasomaculatus) (Subfamily Antelopinae).

Mammalian milk/colostrum usually contains milk oligosaccharides along with the predominant lactose. Although milk oligosaccharides of a variety of Bovidae species including cow, sheep and goat have been characterized, those of the addax, an Antelopinae species of the Bovidae, have not as yet been clarified. In this study, several sialyl oligosaccharides were purified from a sample of addax colostrum and characterized as follows: Neu5Ac(α2-8)Neu5Ac(α2-3)Gal(β1-4)Glc, Neu5Gc(α2-8)Neu5Gc(α2-3)Gal(β1-4)Glc, Neu5Ac(α2-3)Gal(β1-4)Glc, Neu5Ac(α2-6)Gal(β1-4)GlcNAc, Neu5Gc(α2-3)Gal(β1-4)Glc, Neu5Gc(α2-6)Gal(β1-4)Glc, Neu5Gc(α2-6)Gal(β1-4)GlcNAc.

Yersiniosis due to infection by Yersinia pseudotuberculosis 4b in captive meerkats (Suricata suricatta) in Japan.

Two meerkats (Suricata suricatta) housed in the same zoological garden in Japan died due to Yersinia pseudotuberculosis serotype 4b infection. Gross and microscopic lesions included necrotizing enteritis and enlargement of the spleen and liver with multifocal necrosis. Inflammatory cells, primarily neutrophils, and nuclear debris were associated with clusters of Gram-negative bacilli.

Paternity testing using microsatellite DNA markers in captive Adélie penguins (Pygoscelis adeliae).

We investigated the paternity of 39 Adélie penguins (Pygoscelis adeliae) hatched at the Port of Nagoya Public Aquarium between 1995 and 2005 breeding seasons using microsatellite DNA markers. Among the 13 microsatellite marker loci tested in this study, eight markers amplified and were found to be polymorphic in the colony's founders of the captive population (n = 26). Multiple marker analysis confirmed that all the hatchlings shared alleles with their social fathers and that none of them were sired by any male (all males ≥4 years old in the exhibit tank during each reproductive season; n = 9-15) other than the one carrying out parental duties, except in the case of two inbred hatchlings whose half-sibling parents shared the same father.

Daily ingestion of grains of paradise (Aframomum melegueta) extract increases whole-body energy expenditure and decreases visceral fat in humans.

We reported previously that a single ingestion of an alcohol extract of grains of paradise (GP, Aframomum melegueta), a species of the ginger family, increases energy expenditure (EE) through the activation of brown adipose tissue, a site of sympathetically mediated metabolic theromogenesis. The present study aimed to examine a daily ingestion of GP extract on whole-body EE and body fat in humans. Whole-body EE and body fat content were measured before and after daily oral ingestion of GP extract (30 mg/d) for 4 wk in 19 non-obese female volunteers aged 20-22 y in a single-blind, randomized, placebo-controlled, crossover design.

Cross sections for the formation of H(n = 2) atom via superexcited states in photoexcitation of methane and ammonia.

The absolute cross sections for the formation of the H(2s) and H(2p) atoms, σ2s and σ2p, respectively, in photoexcitation of CH4 and NH3 were measured in the range of the incident photon energy 15-48 eV for studying superexcited states of the molecules. The same superexcited states were found to contribute to the σ2s and σ2p cross sections. It was concluded that the non-adiabatic transitions play a significant role during the dissociation of the superexcited states and ionic states.

Intussusception secondary to anaphylactic reaction to salmon roe (ikura).

Anaphylactic food reaction often involves gastrointestinal symptoms, such as vomiting and abdominal pain, but to date, there have been no publications documenting the association between food hypersensitivity and intussusception. Herein is reported the case of a 2-year-old boy with intussusception accompanied by anaphylactic food reaction. The patient without known allergies complained of severe abdominal pain following ingestion of salmon roe for the first time.

Maculopapular rash in the convalescent phase of Kawasaki disease: case series and literature review.

Unlabelled: Intravenous immunoglobulin (IVIG) is currently the standard treatment for Kawasaki disease (KD). Although IVIG therapy is generally well tolerated, several minor adverse reactions have been reported. We report a patient with KD treated with IVIG, who developed a cutaneous reaction in the convalescent phase (approximately 10 days after therapy).

Practical method to derive nonlinear response functions of cameras for scientific imaging.

We developed a practical method to derive response functions that convert the amount of incident light to the counts of analog-to-digital conversion (A/D) of cameras for scientific imaging. In this method, we need a mechanism to accurately control the amount of incident light into cameras just within a limited dynamic range and at a limited number of steps. A variable brightness light source, which supplies the incident light into cameras, is also necessary, but we do not need to know its accurate brightness.

An evaluation of protein intake for metabolic demands and the quality of dietary protein in rats using an indicator amino acid oxidation method.

Currently, protein requirements are generally determined based on nitrogen balance studies, but there are a variety of limitations associated with this method. The indicator amino acid oxidation (IAAO) method, with a theoretical base that differs widely from the nitrogen balance method, was developed as an alternative method for humans. The objective of the present study was to evaluate protein intakes for metabolic demands and protein quality, using protein itself, in rats employing the IAAO technique with L-[1-(13)C]phenylalanine.

Dietary polyunsaturated fatty acids slow the progression of diabetic nephropathy in streptozotocin-induced diabetic rats.

Diabetic nephropathy is associated with lipid deposits in the kidney. We hypothesized that a diet containing polyunsaturated fatty acids (PUFAs) could ameliorate pathogenesis of diabetic kidney diseases associated with lipid depositions in the kidneys. We examined if the pathogenesis and progression of diabetic nephropathy are affected by the type of dietary fat using streptozotocin (45 mg/kg body weight, intravenous)-induced diabetic rats (5-week-old male Sprague-Dawley rats).

Application of a simple asynchronous mechanical light chopper to multielectron coincidence spectroscopy.

A simple asynchronous mechanical light chopper, based on modification of a turbo-molecular pump, has been developed to extend the interval between light pulses in single bunch operation at the Photon Factory storage ring. A pulse repetition rate of 80 kHz was achieved using a cylinder rotating at 48000 rpm, with 100 slits of 80 microm width. This allows absolute timing of particles up to 12.

Large pressure effect on the angular distribution of two Lyman-alpha photons emitted by an entangled pair of H(2p) atoms in the photodissociation of H2.

The angular distribution of two Lyman-alpha photons, i.e., the probability density that two Lyman-alpha photons are emitted in given directions, in the photodissociation of a hydrogen molecule have been measured at the hydrogen gas pressures of 0.

Site-specific fragmentation caused by core-level photoionization in F(3)SiCH(2)CH(2)Si(CH(3))(3) vapor: comparison between Si:1s and 2p photoionizations by means of photoelectron-photoion-photoion triple-coincidence spectroscopy.

Site-specific fragmentation caused by Si:1s and 2p core-level photoionizations in F(3)SiCH(2)CH(2)Si(CH(3))(3) vapor was studied by energy-selected-photoelectron photoion-photoion triple-coincidence spectroscopy. The difference between the chemical shifts of the two Si sites is larger for the 1s ionization than for the 2p (2s) ionization. The fragmentation caused by the Si:1s ionization is more violent than that caused by the Si:2p ionization.

Inner-shell excitation spectroscopy and fragmentation of small hydrogen-bonded clusters of formic acid after core excitations at the oxygen K edge.

Inner-shell excitation spectra and fragmentation of small clusters of formic acid have been studied in the oxygen K-edge region by time-of-flight fragment mass spectroscopy. In addition to several fragment cations smaller than the parent molecule, we have identified the production of HCOOH.H+ and H3O+ cations characteristic of proton transfer reactions within the clusters.

Long-term monitoring of the succession of a microbial community in activated sludge from a circulation flush toilet as a closed system.

The microbial diversity and community succession of a circulation flush toilet were investigated by terminal restriction fragment length polymorphism and cloning analyses. Clonal libraries of 16S rRNA gene on day 3 and day 127 were constructed. On day 3, 102 clones were sequenced; Proteobacteria and Bacteroidetes accounted for 27% and 45%, respectively.

Macrolide-resistant Mycoplasma pneumoniae (MR M. pneumoniae) has been isolated from clinical specimens in Japan since 2000. A comparative study was carried out to determine whether or not macrolides are effective in treating patients infected with MR M.

[Isolation of pancreatic lipase activity-inhibitory component of spirulina platensis and it reduce postprandial triacylglycerolemia].

In the process of investigating the hypolipidemic effects of Spirulina platensis, we found that the aqueous extract of S. platensis may inhibit the intestinal absorption of dietary fat by inhibiting pancreatic lipase activity. The aqueous extract of S.

Successful removal of p-quinone with chitosan in an aqueous phase in relation to degree of deacetylation.

Phenol oxidant is successfully removed by using chitosan particles in the aqueous phase. Removal of p-quinone by chitosan from crab shells was investigated kinetically from molecular weight (MW) of chitosan, deacetylation degree (DD) and reaction temperature. The rate constant assuming first-ordered reaction on removal of p-quinone in aqueous phase primarily depended on the MW of chitosan, not on the DD.

Characterization and molecular analysis of macrolide-resistant Mycoplasma pneumoniae clinical isolates obtained in Japan.

In recent years, Mycoplasma pneumoniae strains that are clinically resistant to macrolide antibiotics have occasionally been encountered in Japan. Of 76 strains of M. pneumoniae isolated in three different areas in Japan during 2000 to 2003, 13 strains were erythromycin (ERY) resistant.
