RESUMEN
BACKGROUND: Somatoform disorders are frequently resistant to treatment. This study aimed to determine the utility of the Minnesota Multifaceted Personality Inventory (MMPI) in predicting the prognosis of somatoform disorders. METHODS: Overall, 125 patients diagnosed with somatoform disorders between January 1, 2013 and December 31, 2017 in the psychiatric department of Fukushima Medical University Hospital were included. Patients with positive outcomes were identified based on a subjective estimation regarding (1) pain and (2) social functions, including activities of daily living. They were divided into the improved group (IG) and the non-improved group (NIG). Each factor was then descriptively compared between the two groups, and the sensitivity and specificity were determined. RESULTS: The NIG had significantly higher scores but only on the Hy scale. Thus, the optimal Hy scale cutoff score was calculated. The cutoff point was 73.5, with a sensitivity of 55.7% and a specificity of 71.7%. CONCLUSION: An MMPI Hy scale score higher than a cutoff value of 73.5 predicts a poor response to conventional supportive psychotherapy or drug therapy in patients with somatoform disorders. This cutoff point may be used as an important index for selecting treatment for somatoform disorders.

The genus Pyelosomum consists of parasitic flukes occurring primarily in marine turtles; Pyelosomum cochlear Looss 1899 is the only species of this genus that parasitizes the urinary bladder. In this study, we detected flukes in the urinary bladders of 20 of 88 green sea turtles (Chelonia mydas) harvested in the Ogasawara Islands, in the Northwest Pacific Ocean. We identified the flukes as P. cochlear based on detailed morphological observations and comparisons of morphometric measurements of the species reported previously. Nucleotide sequences of nuclear ribosomal 18S and 28S regions and the mitochondrial cytochrome c oxidase subunit 1 (COI) region were determined for the flukes. The 18S and 28S phylogenetic trees revealed that the species of the superfamily Pronocephaloidea, including P. cochlear, constituted a single clade, but the species of the family Pronocephalidae did not constitute a single taxon. These findings suggest that Pronocephalidae is a paraphyletic group. The COI sequences of P. cochlear exhibited high genetic diversity, suggesting that they would be useful markers to understand the genetic structure of the parasite and its evolutionary relationship with the host turtle populations. This is the first study to provide the nucleotide sequences of Pyelosomum species; these data will be available for further molecular studies of this genus and its related taxa.

The superfamily Cosmocercoidea comprises three families: Cosmocericidae, Kathlaniidae and Atractidae. Information on the nucleotide sequences of the Cosmocercoidea is quite limited, and the molecular classification of the whole superfamily has been slow to progress. The genus Grassenema of the family Atractidae is a parasitic nematode group that occurs in the digestive tract of hyraxes and includes three species: Grassenema procaviae, G. dendrohyraci, and G. hyracis. The type species of the genus, G. procaviae, was isolated from the digestive tract of Cape hyraxes (Procavia capensis) and has the potential to cause gastric ulcers. Although G. procaviae is a common parasite of Cape hyraxes, no genetic information for the parasite is currently available. In this study, we obtained the first genomic sequences of G. procaviae and performed detailed morphological observations. Furthermore, molecular phylogenetic analysis was performed, and the taxonomic position of the parasite was evaluated using 18S and 28S rDNA sequences. Those data will be useful for molecular identification of G. procaviae and future phylogenetic analysis within the Atractidae.

Trematodes of the genus Rhytidodoides are parasitic in marine turtles. Of the already known species, Rhytidodoides similis Price, 1939, occurs especially in the gall bladder. In this study, we surveyed 73 green sea turtles (Chelonia mydas) in the Ogasawara Islands, Japan, and detected Rhytidodoides sp. from the gall bladders of 18 turtles. A detailed morphological analysis revealed that the forebody of Rhytidodoides sp. differed slightly in shape from that of R. similis. There has been no information on DNA sequences of the family Rhytidodidae. A molecular phylogeny based on 28S rDNA sequences of Rhytidodoides sp. and related taxa suggested that the Rhytidodidae is sister to the other families of Echinostomatoidea. The intraspecific diversity of Rhytidodoides sp. was examined by using DNA sequences of mitochondrial cytochrome c oxidase subunit 1 gene (COI). The population genetic features of the COI haplotypes demonstrated that Rhytidodoides sp. is highly diverse in the Ogasawara Islands. The DNA sequences determined in this study will contribute to the species identification of congeners and the taxonomic reconsideration of the Echinostomatoidea.

We reported before that silica hollow spheres (microcapsules) are prepared by interfacial reaction method that W/O emulsion with the aqueous solution of sodium silicate and n-hexane solution of Tween 80 and Span 80 is combined with another aqueous solution of silica precipitant such as NH(4)HCO(3) and NH(4)Cl. This procedure using W/O/W emulsion fabricates the hollow structures of silica particles directly, and additional steps such as the removal of core parts, that are often essential for the preparation of hollow particles via core-shell materials, are not required. When biomacromolecules such as protein and nucleic acid are mixed in the aqueous solution of sodium silicate, these macromolecules can be encapsulated into the microcapsules. We succeeded the direct encapsulation of bovine serum albumin (BSA) and duplex DNA. Most of encapsulated BSA and DNA cannot be released from the microcapsules without the destruction of microcapsule shell. These microcapsule materials encapsulating biomacromolecules will be applied to biotechnologies such as immobilized enzyme and so on.

OBJECTIVE: To elucidate the impacts of nuclear plant accidents on neighboring medical centers, we investigated the operations of our hospital within the first 10 days of the Great East Japan Earthquake followed by the Fukushima Daiichi nuclear power plant accident. METHODS: Data were extracted from medical records and hospital administrative records covering 11 to 20 March 2011. Factual information on the disaster was obtained from public access media. RESULTS: A total of 622 outpatients and 241 inpatients were treated. Outpatients included 43 injured, 6 with cardiopulmonary arrest, and 573 with chronic diseases. Among the 241 inpatients, 5 died, 137 were discharged, and the other 99 were transferred to other hospitals. No communication methods or medical or food supplies were available for 4 days after the earthquake. Hospital directors allowed employees to leave the hospital on day 4. All 39 temporary workers were evacuated immediately, and 71 of 239 full-time employees remained. These employees handled extra tasks besides patient care and patient transfer to other hospitals. Committed effective doses indicating the magnitude of health risks due to an intake of radioactive cesium into the human body were found to be minimal according to internal radiation exposure screening carried out from July to August 2011. CONCLUSIONS: After the disaster, hospitals located within the evacuation zone of a 30-km radius of the nuclear power plant were isolated. Maintenance of the health care system in such an event becomes difficult.

Polyamines such as spermidine (Spd) and spermine (Spm), produced by aminopropyltransferase (Apt), play roles in cell growth and differentiation. A sensitive and simple fluorometric high-performance liquid chromatographic determination for Apt activity of spermidine synthase (Spdsyn) and spermine synthase (Spmsyn) was developed in order to examine cellular functions of polyamine synthesis. The derivatization procedure for methylthioadenosine (MTA) produced from decarboxylated S-adenosylmethionine by Apt was the reaction with 2-chloroacetaldehyde to give fluorescent 1, N(6)-etheno methylthioadenosine. The reaction conditions for derivatization were optimized. A calibration curve was established, ranging from 0.01 to 25 pmol. Quantification of derivatized MTA was confirmed to be identical to Spd or Spm production. The developed method determined Spdsyn and Spmsyn activities in HepG2 cells treated with oleic acid as a cellular lipid accumulation model.
