Abstract
Patients with cancer die from cardiac dysfunction second only to the disease itself. Cardiotoxicity caused by anticancer drugs has been emphasized as a possible cause; however, the details remain unclear. To investigate this mechanism, we treated rat cardiomyoblast H9c2 cells with sunitinib, lapatinib, 5-fluorouracil, and cisplatin to examine their effects. All anticancer drugs increased ROS, lipid peroxide, and iron (II) levels in the mitochondria and decreased glutathione peroxidase-4 levels and the GSH/GSSG ratio. Against this background, mitochondrial iron (II) accumulates through the unregulated expression of haem oxygenase-1 and ferrochelatase. Anticancer-drug-induced cell death was suppressed by N-acetylcysteine, deferoxamine, and ferrostatin, indicating ferroptosis. Anticancer drug treatment impairs mitochondrial DNA and inhibits oxidative phosphorylation in H9c2 cells. Similar results were observed in the hearts of cancer-free rats treated with anticancer drugs in vitro. In contrast, treatment with pterostilbene inhibited the induction of ferroptosis and rescued the energy restriction induced by anticancer drugs both in vitro and in vivo. These findings suggest that induction of ferroptosis and inhibition of oxidative phosphorylation are mechanisms by which anticancer drugs cause myocardial damage. As pterostilbene ameliorates these mechanisms, it is expected to have significant clinical applications.

Abstract
Anticancer agents are playing an increasing role in the treatment of gastric cancer (GC); however, novel anticancer agents have not been fully developed. Therefore, it is important to investigate compounds that improve sensitivity to the existing anticancer drugs. We have reported that pterostilbene (PTE), a plant stilbene, enhances the antitumor effect of low doses of sunitinib in gastric cancer cells accumulating mitochondrial iron (II) (mtFe) at low doses. In this study, we investigated the relationship between the mtFe deposition and the synergistic effect of PTE and different anticancer drugs. For this study, we used 5-fluorouracil (5FU), cisplatin (CPPD), and lapatinib (LAP), which are frequently used in the treatment of GC, and doxorubicin (DOX), which is known to deposit mtFe. A combination of low-dose PTE and these drugs suppressed the expression of PDZ domain-containing 8 (PDZD8) and increased mtFe accumulation and mitochondrial H2O2. Consequently, reactive oxygen species-associated hypoxia inducible factor-1α activation induced endoplasmic reticulum stress and led to apoptosis, but not ferroptosis. In contrast, 5FU and CDDP did not show the same changes as those observed with PTE and DOX or LAP, and there was no synergistic effect with PTE. These results indicate that the combination of PTE with iron-accumulating anticancer drugs exhibits a strong synergistic effect. These findings would help in developing novel therapeutic strategies for GC. However, further clinical investigations are required.

Abstract
[Purpose] Behavioral analysis is widely used in animal research. However, such analysis requires specialized equipment and can be difficult to perform. Therefore, this study aimed to explore and validate a simple behavioral analysis method. [Participants and Methods] For behavioral assessments, Wistar rats were placed in a rearing cage and videotaped from two directions: overhead and side view. The filmed videos were analyzed using ImageJ software to calculate the distance traveled and activity and inactivity times of the rats. Intraclass correlation coefficients 1 and 2 were calculated to examine the reliability of the behavioral analysis method. [Results] Intraclass correlation coefficients 1 and 2 for distance traveled and activity and inactivity times determined using the behavioral analysis method showed high reliability. [Conclusion] The behavioral analysis method validated in this study used inexpensive and easily accessible equipment and devices. The results show high correlation coefficients for the measurement of distance traveled and activity time performed by experimental animals, demonstrating the reliability of this simple method.

Abstract
[Purpose] The purpose of this study was to investigate the effects of glucose intake on physical function in a heart failure rat model. [Materials and Methods] Five-week-old male Wistar rats were used for this study. Monocrotalin (40 mg/kg) was administered intraperitoneally to rats to induce heart failure. The rats were divided into two groups, control and MCT; the MCT group was further classified according to glucose concentration (0%, 10%, and 50%). [Results] Glucose intake during heart failure prevented the loss of body weight, skeletal muscle, and fat mass. Myocardial metabolism in heart failure was enhanced by hypoxia, which in turn, enhanced the glycolytic system. [Conclusion] Glucose loading suppressed cardiac hypertrophy and improved physical function in the heart failure rat model.

Abstract
[Purpose] To assess the effects of continuous rehabilitation on intensive care unit-acquired weakness in a patient who underwent open-heart surgery. [Participant and Methods] This case report describes a 78-year-old female patient who developed intensive care unit-acquired weakness after open-heart surgery. She underwent cardiac surgery, via a thoracotomy, for valvular disease and angina pectoris. Her Medical Research Council sum score at the time of rehabilitative intervention was 28 points, indicating intensive care unit-acquired weakness. Rehabilitation was continued, and the patient's physical function was evaluated over time. [Results] Continuous rehabilitation improved the patient's grip strength, knee extension muscle strength, 6-minute walk test performance, and Short Physical Performance Battery score. [Conclusion] Although few reports have been published on rehabilitation for patients with intensive care unit-acquired weakness, our case suggests that appropriate rehabilitative intervention according to the severity of the condition and continuous rehabilitation may improve the patients' activities of daily living and physical function.

Abstract
5-aminolevulinic acid (ALA) is used for tumor-targeting phototherapy because it is converted to protoporphyrin IX (PPIX) upon excitation and induces phototoxicity. However, the effect of ALA on malignant cells under unexcited conditions is unclear. This information is essential when administering ALA systemically. We used sarcoma cell lines that usually arise deep in the body and are rarely exposed to light to examine the effects of ALA treatment under light (daylight lamp irradiation) and dark (dark room) conditions. ALA-treated human SW872 liposarcoma cells and human MG63 osteosarcoma cells cultured under light exhibited growth suppression and increased oxidative stress, while cells cultured in the dark showed no change. However, sphere-forming ability increased in the dark, and the expression of stem-cell-related genes was induced in dark, but not light, conditions. ALA administration increased heme oxygenase 1 (HO-1) expression in both cell types; when carbon monoxide (CO), a metabolite of HO-1, was administered to sarcoma cells via carbon-monoxide-releasing molecule 2 (CORM2), it enhanced sphere-forming ability. We also compared the concentration of biliverdin (BVD) (a co-product of HO-1 activity alongside CO) with sphere-forming ability when HO-1 activity was inhibited using ZnPPIX in the dark. Both cell types showed a peak in sphere-forming ability at 60–80 μM BVD. Furthermore, a cell death inhibitor assay revealed that the HO-1-induced suppression of sphere formation was rescued by apoptosis or ferroptosis inhibitors. These findings suggest that in the absence of excitation, ALA promotes HO-1 expression and enhances the stemness of sarcoma cells, although excessive HO-1 upregulation induces apoptosis and ferroptosis. Our data indicate that systemic ALA administration induces both enhanced stemness and cell death in malignant cells located in dark environments deep in the body and highlight the need to pay attention to drug delivery and ALA concentrations during phototherapy.

Abstract
Water gas shift reaction of carbon monoxide (CO) with membrane reactors should be a promising method for hydrogen mass-production because of its high CO conversion, high hydrogen purity and low carbon dioxide emission. For developing such membrane reactors, we need hydrogen permselective membranes with high hydrogen permeance with order of 10−6 mol m−2 s−1 Pa−1 at 573 K and high steam durability. In this study, we have optimized the kind of substrates, precursors, vapor concentration, and chemical vapor deposition (CVD) time using the counter-diffusion CVD method for developing such membranes. The developed membrane prepared from hexamethyldisiloxane has a hydrogen permeance of 1.29 × 10−6 mol m−2 s−1 Pa−1 at 573 K and high steam durability. We also conducted water gas shift reactions with membrane reactors installed the developed silica membranes. The results indicated that reactions proceed efficiently with the conversion around 95–97%, hydrogen purity around 94%, and hydrogen recovery around 60% at space velocity (SV) 7000.

Abstract
A mixture of two monoterpenes was obtained as the opisthonotal gland secretion from unidentified Histiogaster sp. A096 (Acari: Acaridae), and their structures were elucidated to be (4E)-dehydrocitrals [(2E,4E)- and (2Z,4E)-3,7-dimethyl-2,4,6-octatrienals] by GC/MS, GC/FT-IR, UV and 1H-NMR spectra. Both isomers of (4E)-dehydrocitral prepared by syntheses in 4 steps from 3-methyl-2-butenal with 34.2% yields (based on the ylide) were separated by column chromatography into the (2E,4E)- and (2Z,4E)-3,7-dimethyl-2,4,6-octatrienal. Mass spectra together with GC retention times of the purified natural (4E)-dehydrocitrals were identical with those of synthetic (2E,4E)-3,7-dimethyl-2,4,6-octatrienal and (2Z,4E)-3,7-dimethyl-2,4,6-octatrienal. The geometry at the 2-C position of both synthetic (4E)-dehydrocitrals was confirmed by NOESY analyses. This is the first identification of (4E)-dehydrocitrals from the animal kingdom.

Abstract
To discover the relationship between a leaf-rolling moth and the fungi densely covering its cocoons, the rolled nest leaves were collected in two districts in Japan and antibacterial properties of the fungi were examined. Cocoons and fungi isolated from the nest were classified into 5 categories by the growth stages of the insects, and 7 categories based on taxonomic properties and pigment productivity, respectively. The dominant genus was Penicillium in each location. However, the composition of the fungal categories was different and seemed to depend on their circumstances. From all cocoons with larvae, the strains that belonged to the same fungal category and produced the same antibiotic (deoxyherqueinone) were isolated. From these results, the species-specific relationship between the insect and fungi or fungal products was considered to be not extremely tight, and it was suggested the period of the larval spinning of the cocoon is a key stage of this unique relationship.

Abstract
BACKGROUND AND AIMS Mucinous gastric carcinoma (MUC) is relatively a rare subtype of gastric carcinoma, and there has been considerable controversiy over the prognosis of this type of carcinoma. In this study we tried to analyze the clinicopathological differences between MUC and other types of gastric carcinoma (non-MUC) and determine whether MUC is associated with a worse prognosis than non-MUC. MATERIAL AND METHODS We reviewed 645 patients with pathologically confirmed gastric cancer who underwent gastrectomy in our facility during the period from 1975 through 1997. Among them, 20 patients (3.1%) had gastric carcinoma with (MUC), and 625 patients had it without extracellular mucin (non-MUC). In addition, we classified MUC into two groups (well-differentiated type; 7 cases and poorly differentiated type; 9 cases) and analyzed the differences between them. RESULTS The MUC tumors were more often located in the lower and the upper third of the stomach (MUC: 55% and 25%, non-mUC: 41% and 18%, respectively). The patients with MUC had more serosal invasion (t3 plus t4; MUC: 45%, non-MUC: 18%), more-invasive carcinoma (Type 3 plus 4; MUC: 60%, non-MUC: 36%) and more lymph-node involvement (MUC: 45%, non-MUC: 38%) than the patients with non-MUC. The patients with MUC were more advanced in stage at the time of diagnosis (Stage III plus IV; MUC: 50%, non-MUC: 26%) and had a higher peritoneal dissemination rate (MUC: 30%, non-MUC: 12%) and a lower curability rate (MUC: 60%, non-MUC: 78%) than the patients with non-MUC. The mean size of tumors in MUC (7.4 cm) was larger than that of non-MUC (5.5 cm). Therefore, the overall 5-year survival rate for MUC patients (33%) was lower than that for non-MUC patients (64%). There were no significant differences between well-differentiated and poorly differentiated subtypes of MUC except for the curability and peritoneal dissemination rates. CONCLUSIONS The overall survival rate for patients with MUC was worse than that for patients with non-MUC. The poor prognosis was correlated with more advanced stage at diagnosis and more frequent serosal invasion. These results suggest the need to diagnose patients with MUC in the early stage of cancer and that in the case of the advanced stage, wide excision of the surrounding tissues and aggressive lymph-node dissection will be needed.

Abstract
OBJECTIVE The purpose of this article was to study and clarify the features of Chinese herb nephropathy (CHN) in Japan. PATIENTS AND METHODS The subjects consisted of patients diagnosed as having CHN in Saiseikai Nakatsu Hospital and of those reported in the literature in Japan. We investigated the clinical and histological features of CHN patients in Japan and compared them with the Belgian cases. RESULTS The remarkable differences were as follows: (1) high prevalence in males compared with Belgian cases, (2) Fanconi syndrome was found in most cases, (3) no patients had malignant tumors in the urinary tract. In addition, the ascribed Chinese medicines in Japan were divided into three groups: 'Tenshin-toki-shigyaku-ka-gosyuyu-syokyo-to', 'Boui-ougi-to', and others. CONCLUSION CHN in Japan has some characteristics distinguished from Belgian nephropathy. One hypothesis is a susceptibility to aristolochic acids (AAs), which is considered to be a causative agent, may be different among races. Another is that there could be some other toxic substances affecting the clinical findings although they are not identified at present. Further studies must be undertaken to clarify these differences.

Abstract
BACKGROUND In Japan the patients with Chinese herbs nephropathy (CHN), aristolochic acids-(AAs) associated renal failure, often present Fanconi syndrome. The aim of this study was to investigate the pattern of aminoaciduria in patients with AAs-induced Fanconi syndrome and to clarify whether it is different from other Fanconi syndromes reported in the literature. SUBJECTS AND METHODS The subjects consisted of 4 patients with Fanconi syndrome due to AAs. We studied biochemical data and urinary excretion of amino acids in the 4 patients. Amino acids in their urine were analyzed by high performance liquid chromatography (HPLC). RESULTS Three out of 4 patients showed in common very increased excretion ofproline, hydroxyproline and citruline. Last patient showed the very increased levels of proline and valine. Regarding glycine, which is considered to belong to the same group as imino acid and to be shared with high-affinity transport system ofproline, there was not very increased excretion. CONCLUSION These findings suggest that AAs would predominantly affect the low-affinity transport system of proline in the brushborder membrane of proximal tubules because the low-affinity system is considered not to be shared with glycine transport.

Abstract
The oviposition response of the Rutaceae-feeding swallowtail butterfly, Papilio bianor, was induced by a methanolic extract from leaves of its major host, Orixa japonica. Several components were responsible for this oviposition response. One of the stimulants was isolated and identified as (-)-2-C-methyl-D-erythrono-1,4-lactone. The compound was inactive alone, but elicited oviposition behavior when mixed with other fractions.

Abstract
A unique protein of 23 kDa (Jf23) was found in the tarsus of the female swallowtail butterfly, Atrophaneura alcinous. Jf23 has 38% identity with a bilin-binding protein, which was found in the cabbage butterfly, Pieris brassicae, and which has two consensus sequences in common with the members of the lipocalin family, suggesting that it is a binding protein for lipophilic ligands. Western blot analysis showed that Jf23 was expressed only in the female, and not in the male. Electrophysiological response of the female tarsi was stimulated by methanolic extract of their host plant, Dutchman's pipe (Aristolochia debilis). The stimulated response was depressed by the presence of Jf23 antiserum. These results suggest that Jf23 is one of the chemosensory signaling proteins, which plays one or more roles in female butterfly oviposition.

Abstract
BACKGROUND We encountered two cases of Chinese herb-induced Fanconi syndrome in Japan. One component of the chinese medicine was "Kan-mokutsu" (Aristolochia manshuriensis) in which aristolochic acids (AAs) were detected. METHODS Renal biopsy showed flattening of proximal tubular epithelial cells and paucicellular interstitial fibrosis without glomerular lesions, all of which were in accordance with Chinese herb nephropathy (CHN). To date, many cases of CHN have been reported mainly as progressive renal failure in western countries. RESULTS However, our cases were different from those in that they presented Fanconi syndrome. The detected AAs in our cases consisted of aristolochic acid (AA)-I, II and D. In contrast, in Belgium, the incriminated agent was Aristolochia fangchi which consisted of AA-I, B, C, and aristolactum. CONCLUSION These findings could indicate that different components of AAs could cause different clinical lesions, or that the amount of ingested AAs might reflect clinical pictures, that is to say, our patients took lower volume of Chinese herbs and might be in an early stage of CHN. Furthermore, it is likely that susceptibility to this substance may be different among races. CHN would include two clinical aspects: subacute renal failure and adult-onset Fanconi syndrome. It is important to bear in mind that CHN could present Fanconi syndrome.

Abstract
The electroreduction of alkylaryldichlorosilane carried out with Mg cathode and anode in a single compartment cell gave high molecular weight poly(alkylarylsilane) (M(n) = 5200-31000, M(w)/M(n) = 1.4-1.8) in 5-79% yield. The effects of electrode material, monomer concentration, amount of supplied electricity, and ultrasound were investigated. This electroreductive method was also successfully applied to the synthesis of polygermanes, silane-geramane copolymers, and also poly[p-(disilanylene)phenylenes].

Abstract
BACKGROUND Xiao zhi ling (XZL), which consists of Chinese nutgalls and aluminium potassium sulphate, is used as a local injection for the treatment of internal haemorrhoids in China. It is also used for endoscopic sclerotherapy of oesophageal varices. To date, however, it has not been compared with other sclerosants with regard to its safety and efficacy. METHODS In the present study, the effect on the endothelium and the haemolytic and thrombosing effects of XZL were compared with those of 5% ethanolamine oleate and 1% polidocanol, using an endothelial cell line and red blood cells taken from rats and the dorsal marginal ear vein of rabbits. In addition, XZL was injected into the area surrounding varices in rats and its efficacy was studied endoscopically and histologically. RESULTS Xiao zhi ling reduced the size of varices in rats after causing severe damage in the injected region. Compared with the other two sclerosants, however, XZL had little effect on the endothelium and was the least haemolytic compound. Furthermore, XZL did not cause thrombosis in the injected vein of a rabbit. CONCLUSIONS These results suggest that XZL is another type of sclerosant with astringent rather than detergent properties. This compound should be used to treat oesophageal varices by paravariceal injection in smaller doses than 5% ethanolamine oleate and 1% polidocanol.

Abstract
Animal models resembling the human situation are very useful to investigate human disease. However, there has been no evidence of esophageal varices in rats with liver cirrhosis. In the present study, to determine whether intrahepatic portal hypertension produced by liver cirrhosis induces esophageal varices in rats, the esophagus was examined endoscopically in rat models of liver cirrhosis. All rats given carbon tetrachloride or thioacetamide and six of seven rats given a choline-deficient diet had esophageal varices or venous dilatation after 16 weeks of treatment, although the varices in one rat given carbon tetrachloride and in two rats given a choline-deficient diet were reduced from weeks 16 to 18. These findings suggest that timing is important when studying esophageal varices in rat models of liver cirrhosis. It is concluded that certain models of liver cirrhosis in rats could be used as models of esophageal varices due to intrahepatic portal hypertension.

Abstract
A 19-year-old female was referred to our hospital for azotemia and anemia. She had been taking a health food for atopic dermatitis for about three years. Urinalysis showed proteinuria, glycosuria and microscopic hematuria. Generalized aminoaciduria was observed. Moreover, severe anemia, azotemia, hypokalemia and hypophosphatemia were also observed. Renal biopsy specimen disclosed hypocellular interstitial fibrosis and degeneration of the proximal tubular epithelial cells. No remarkable changes were observed in the glomeruli. Aristolochic acid was detected in the health food. From these findings, she was diagnosed as having Chinese herbs nephropathy (CHN). Although consumption of the food intake was stopped, her renal function deteriorated rapidly. Previously, we reported that certain kinds of Chinese herbal drugs contain aristolochic acid and that the drugs should be prohibited if aristolochic acid is identified. However, we experienced a patient of CHN arising from traditional remedy, which was not proved to be safe. It should be awared that health foods may contain aristolochic acid.

Abstract
The effect of trypsin inhibitor (TI) in soybean on the prevention of cancer has been reported in animal studies. However, the actual intake of active TI in daily life is not known. In this experiment we measured TI activity in various soybean products and the effects of some factors of processing on the TI activity. Average TI activity in whole soybean was 4,819 U/100 g, and the average percentages of remaining activity in products against that of whole soybean were momen-tofu 2.5%, yose-tofu 3.4%, kinugoshi-tofu 4.3%, jyuten-tofu 7.9%, soymilk 13.0%, natto 0.7%, soy sauce 0.8% and miso 0.3%. By heating soymilk at 100 degrees C, TI activity decreased to 11% at 10 min and 5% at 20 min. After heating soymilk in a water-bath for 15 min at 75 and 100 degrees C, TI activity decreased to 35 and 12%, respectively. The TI activity of tofu was proportional to the remaining whey. The effects of chemicals used for the coagulation of soy protein and foam-removal on TI activity were little. The results suggest that soybean products retain 2.5-12.5% TI activity of the whole soybean and that humans are consuming some active TI in their daily lives.

Abstract
In 1993, Vanherweghem and his associates reported cases of rapidly progressive renal interstitial fibrosis in young women who were administered a slimming regimen including Chinese herbs. Subsequently, similar cases have been reported. In Japan, especially in the Kansai area, several cases of Chinese herbs nephropathy have already been reported. We experienced a patient suffering from Chinese herbs nephropathy (CHN), and further detected aristolochic acids from the Chinese herbs taken by the patient. Aristolochic acids are known to be causative agents of CHN. The danger of CHN should be noted as soon as possible and drugs containing aristolochic acids should be prohibited.

Abstract
Male Idea leuconoe butterflies release a complex mixture of volatiles from their pheromone glands (hairpencils) during courtship. The pheromone components geranyl methyl thioether (2), viridifloric beta-lactone (3) and 6-hydroxy-4-dodecanolide (10) have been synthesized for the first time. Therefore, the structural assignment of these new natural products could be proved. Related 7-hydroxy-5-alkanoides are also present in the extract. The volatiles are embedded in a lipidic, matrix with more than 150 components. This matrix consists of alkanes, alkenes, 2,5-dialkyltetrahydrofurans, secondary alkanols and alkenols as well as alkanones and alkenones. Several regioisomers of the oxidized hydrocarbons occur. The elucidation of double bond positions has been performed by MS using DMDS adducts.

Abstract
BACKGROUND Partial ligation of the portal vein has been shown to induce not only prehepatic portal hypertension but also esophageal varices in the rat. We developed an esophageal endoscopic system for endoscopic sclerotherapy of esophageal varices in rats. In the present study the efficacy of three sclerosing agents, 1% polidocanol, 5% ethanolamine oleate, and 99.5% ethanol, was compared, using this model. METHODS Sclerosing agents were injected paravariceally in 42 rats with partial portal vein ligation. Their efficacy was compared endoscopically and histologically. RESULTS Ethanol induced the most severe ulcers and subsequent stricture formation. The damage induced by 1% polidocanol was mild and healed quickly, whereas 5% ethanolamine oleate induced moderate damage. The varices disappeared because of fibrosis that developed after ulceration. CONCLUSIONS The results were consistent with the known properties of these three agents, suggesting that the esophageal endoscopic system for sclerotherapy in rats provides a useful method for experimental studies of sclerotherapy.

Abstract
Luehdorfia japonica Leech (Papilionidae, tribe Zerynthiini) is a swallowtail butterfly whose larvae feed exclusively on the plant genus Heterotropa (Aristolochiaceae). Luehdorfia japonica females were strongly stimulated to lay eggs on filter paper treated with a methanolic extract of the host plant leaves. The oviposition stimulant factor was composed of several water-soluble components. One of the oviposition stimulants was isolated from the leaves of Heterotropa aspera and identified as isorhamnetin 3-O-glucosyl-(1-->6)-galactoside-7-O-glucoside. This compound was inactive alone but induced the specific oviposition response from L. japonica females when tested as a mixture with other unidentified components.

Abstract
A new bio-antimutagen, petasiphenol [3-(3,4-dihydroxyphenyl)-2-oxopropyl caffeate] (1) was isolated from scapes of Petasites japonicum (AD50 = 95 micrograms/ml against UV-induced mutagenic E. coli WP2 B/r Trp-. Petasiphenol (1) and its isomer (2) were synthesized. The activity of 1 was observed in the presence of soybean oil (glyceride), although the isomer (2) did not show any activity in doses up to 300 micrograms/ml.

Abstract
A blend of ethyl trans-cinnamate, methyl 2-epijasmonate, methyl jasmonate, and (R)-(-)-mellein, identified from the hairpencils of male Oriental fruit moths, attracts sex pheromone-releasing females several centimeters away. The chemicals thereby duplicate the behavioral effect elicited by hairpencil-displaying males during courtship; the chemicals also produce the herbal scent emanating from the hairpencils.
