Abstract
During pregnancy, the maternal environment is critical for normal ontogeny and central nervous system development. Occasionally, prenatal exposure to environmental factors affects tissue architecture and functional development of the brain, which causes developmental disorders, including disorders of the autism spectrum. One of these environmental factors is the exposure to infectious diseases during pregnancy. In this study, we generated mice with infectious disease-induced inflammation by prenatal exposure to 200 μg/kg polyinosinic-polycytidylic acid sodium salt [Poly(I:C)] at embryonic day 12.5 and analyzed their phenotypes on 30-weeks-old. We attempted to detect abnormalities in spontaneous activity and social interaction, which may be indicators of developmental disorder-like behavioral abnormalities, in free-ranging behaviors in multiple rearing environments using multiple animal positioning systems and UMATracker in mice with fetal inflammation. Increased spontaneous activity and abnormal social interactions were observed in mice in the Poly(I:C)-treated group compared with those in the control group. Prenatal exposure to Poly(I:C) increased motor activity and decreased social interaction, and social behavior in prenatally treated mice in a multiple-individual rearing environment. Poly(I:C) exposure during the fetal period resulted in developmental disorder-like behavioral abnormalities, such as increased activity and abnormal social interactions, even after maturation in a multiple-individual rearing environment. This experimental method may provide a new way to analyze the behavior of mouse models of developmental disorders in a multiple-individual rearing environment, in which free-ranging behavior is possible.

Abstract
We have established a new method for allogeneic pancreatic islet (PI) transplantation: relatively low doses of irradiation followed by simultaneous transplantation of PIs and bone marrow cells (BMCs) via the portal vein (PV). In the present study, we have compared this method with intra-bone marrow (IBM)-bone marrow transplantation (BMT), and with a combination of both methods. Streptozotocin (STZ)-induced diabetic-recipient rats, Fischer 344 (F344, RT1A(l), RT1B(l)), were irradiated 1 day before transplantation. PIs of Brown Norway rats (BN, RT1A(n), RT1B(n)) were transplanted into the liver of the diabetic F344 rats via the PV. BMCs from BN rats were injected into the recipients' bone marrow (IBM), PV or intravenously (IV) or by a simultaneous combination of PV plus IBM (PV+IBM). We compared graft survival among the groups of '9 Gy+IBM'(10/10 accepted), '9 Gy+PV'(7/10 accepted), '9 Gy+IV'(0/7 accepted), '9 Gy+PV+IBM'(8/8 accepted), '8.5 Gy+IBM'(4/9 accepted), '8.5 Gy+PV'(0/7 accepted), '8.5 Gy+IV'(0/7 accepted), '8.5 Gy+PV+IBM'(9/12 accepted), '8 Gy+IBM'(2/10 accepted) and '8 Gy+PV+IBM'(2/8 accepted). As we reported previously, PV-BMT is more effective in inducing the acceptance of allogeneic PIs than IV-BMT. However, IBM-BMT requires less pretreatment than PV-BMT. (PV+IBM)-BMT was found to be the most effective in inducing the acceptance of allogeneic PIs. These results suggest that allogeneic PI-transplantation in conjunction with (PV+IBM)-BMT could become a viable strategy.

Abstract
Asterriquinone (ARQ) is an antitumor metabolite of Aspergillus terreus IFO 6123. In this study we synthesized several ARQ alkyl ethers and studied their cytotoxic activity against mouse leukemia P388 cells. The dissociation constant was also similar among the ARQ monoalkyl ethers. There was a good correlation between the hydrophobicity of ARQ monoalkyl ethers estimated by high performance liquid chromatography and the intracellular content accumulated for 60 min. ARQ monoalkyl ethers were cytotoxic, but ARQ dimethyl ether was not, as previously reported. The cytotoxicity of the ARQ monoalkyl ether derivatives was increased with extension of the alkyl chain length. The cytotoxicity was closely correlated with the intracellular content. The strongest ARQ derivative, ARQ monohexyl ether (ARQHex), formed more DNA-interstrand cross-links in the cells than ARQ. After treatment of P388 cells with ARQ and ARQHex for 6 h, a nucleosomal ladder pattern, as well as the appearance of degraded DNA, observed by flow cytometry, indicated that these compounds caused cellular apoptosis. Moreover, ARQ and ARQHex accumulated in the cells at the G1 phase of the cell cycle. These results indicated that ARQ monoalkyl ethers increased cytotoxicity, according to their membrane permeability based on the hydrophobicity, and they caused apoptotic cell death, as did ARQ.

Abstract
Asterriquinone (ARQ) is an antitumor metabolite of Aspergillus terreus IFO 6123. ARQ is a quinone compound and the mechanism of its antitumor action was compared with that of its analog ARQDMe which was dimethylated at the dihydroxy benzoquinone moiety, and adriamycin (ADR). The cytotoxicity of ARQ against P388 cells was less than that of ADR, and ARQDMe showed hardly any cytotoxicity. ARQ and ADR formed DNA-interstrand cross links (ISC) in P388 cells in a concentration while the ISC index by ARQDMe was very low even at 10 microM. P388 cells treated with ARQ and ADR for 18 hours showed, dose-dependently, nucleosomal ladder formation as well as the appearance of degraded DNA. Difference between the action of ARQ and ADR were observed by flow cytometric cell cycle analysis. ARQ caused the cells to accumulate at the G1 phase of the cell cycle, while use of ADR led to arrest in the G2/M phase. ARQDMe never caused apoptotic changes or cell cycle alterations. These results indicate that ARQ intercalates in the genomic DNA, causes G1 arrest, and leads to apoptotic cell death, this suggests that the dihydroxybenzoquinone moiety of the compound is essential to elicit these actions.

Abstract
Four new metabolites (1-4) were isolated from mycelium of Aspergillus terreus IFO 6123 producing asterriquinone (ARQ). The structures of 1 and 2 were shown to be 3,6-bis[1-(1,1-dimethyl-2-propenyl)-1H-indol-3-yl]-furo[3,2-b]furan- 2,5-dione (asterridinone) and 2,5-bis[1-(1,1-dimethyl-2-propenyl)-1H-indol-3- yl]-3-acetoxy-6-hydroxy-2,5-cyclohexadiene-1,4-dione (ARQ monoacetate), respectively, by the chemical and spectral data. Compounds 3 and 4 were identified with known asterriquinone isomers, 2-[1-(1,1-dimethyl-2-propenyl)-1H-indol-3-yl]-5-[2-(3-methyl-2-butenyl)- 1H-indol-3-yl]-3,6-dihydroxy-2,5-cyclohexadiene-1,4-dione (isoARQ) and 2,5-bis[2-(3-methyl-2-butenyl)-1H-indol-3-yl]-3,6-dihydroxy- 2,5-cyclohexadiene-1,4-dione (neoARQ), respectively.

Abstract
ST segment elevation in right precordial leads is thought to be good predictor of right ventricular involvement in patients with acute inferior myocardial infarction. This view, however, is rapidly disappearing. Therefore, using QRS changes in body surface potential maps in the chronic phase, we have attempted to differentiate patients with or without right ventricular involvement. Thirty patients with chronic inferior myocardial infarction (2 or more months after onset) were studied, in whom 87 unipolar ECGs and right ventriculograms were recorded. The patients were then divided into three groups depending on the locations of their abnormal QRS potentials (-2SD area) exceeding the normal range (mean -2SD). In group A, the -2SD area was located predominantly on the right inferior chest, in group B on the left inferior chest, and in group N on both the right and left inferior chests equally. The results showed that group A had a lower right ventricular ejection fraction (RVEF) compared with group B (A, 40 +/- 7%; B, 53 +/- 10%; p less than .001), while there was no difference in left ventricular ejection fraction between the two groups (49 +/- 11% and 49 +/- 11%, respectively). Moreover, right ventricular asynergy occurred in 14 of the 18 patients (78%) of group A but in only one of the 10 patients (10%) of group B. Group N was presumed to be intermediate between groups A and B.(ABSTRACT TRUNCATED AT 250 WORDS)
