Diversity and compositions of the Lactobacillus, Streptococcus, and Bifidobacterium group in the feces of six healthy, actively racing horses (Thoroughbreds) were analyzed by using PCR-denaturing gradient gel electrophoresis (DGGE) and real-time PCR with primer sets specific for each group. PCR-DGGE analysis of the feces showed that Lactobacillus equi, Lactobacillus johnsonii, a phylogenetic relative of Lactobacillus salivarius, a phylogenetic relative of Lactobacillus gastricus, and Weissella confusa were predominant in almost all of the feces tested, and Streptococcus bovis/Streptococcus equinus was predominant in the Streptococcus group. The Bifidobacterium group was not detected by single-PCR but atypical species of the group were found in three of the six Thoroughbreds tested by nested-PCR. Calculation and estimation of lactic acid bacteria and bifidobacteria revealed that lactic acid bacteria were predominant in the feces and bifidobacteria were minor. These results indicate that the community of lactic acid bacteria and bifidobacteria in horse feces are unique because of the presence of specific species for horse feces and a minority of the Bifidobacterium group. Repeated tests of the feces from the same horse over 3 months showed that the diversity and composition of lactic acid bacteria and bifidobacteria in the feces was basically stable throughout the test period.

Alzheimer’s disease (AD) is the most common neurodegenerative disorder, characterized by progressive neuronal loss with amyloid β-peptide (Aβ) plaques. Despite several drugs currently used to treat AD, their beneficial effects on AD progress remains under debate. Here, we established a rapid in vivo screening system using Drosophila AD models to assess the neuroprotective activities of medicinal plants that have been used in traditional Chinese medicine. Among 23 medicinal plants tested, the extracts from five plants, Coriandrum sativum, Nardostachys jatamansi, Polygonum multiflorum (P. multiflorum), Rehmannia glutinosa, and Sorbus commixta (S. commixta), showed protective effects against the Aβ42 neurotoxicity. We further characterized the neuroprotective activity of ethanol extracts from P. multiflorum and S. commixta. Aβ42-expressing flies that we used showed AD neurological phenotypes, such as decreased survival and motility and increased cell death and reactive oxygen species level. However, feeding these flies extracts from P. multiflorum or S. commixta showed strong suppression of such phenotypes. Similar results were observed in human cells, so that the treatment of P. multiflorum and S. commixta extracts increased the viability of Aβ-treated SH-SY5Y cells. Moreover, 2, 3, 5, 4'-tetrahydroxystilbene-2-O-β-D-glucoside, one of the main constituents of P. multiflorum, also showed similar protective activity against Aβ42 cytotoxicity in both Drosophila and human cells. Taken together, our results suggest that both P. multiflorum and S. commixta have therapeutic potential for the treatment of neurodegenerative diseases, such as AD.

This paper examines the sociological factors in the in-situ conservation of traditional varieties of sorghum in the Yamato Highlands, Nara prefecture. In village A, red sorghum is still grown to color red bean rice, an auspicious food used in celebrations. A village enterprise dedicated to food processing plays a key role in red sorghum production. Elderly females grow this crop to dye other products bright red, the color favored by fellow villagers. In the adjacent village B, which has no enterprises, the same red sorghum is grown by some households but strictly for domestic consumption. In both cases, social relations based on reciprocity within the neighborhood and family are important factors in maintaining this kind of traditional food and crop.

This study was to investigate the effects of exercise experienced in youth on the genital function from menarche to menopause. One thousand and seven females after menopause aged from 45 to 88 completed the questionnaires. The results were as follows.1) The age of menarche became significantly younger as years went on.2) Females who had exercised in youth was significantly ahead of those who had not exercised in youth in menarche. The age of menarche was significantly earlier in more exercised group than in less exercised group.3) The frequency of pregnancy and delivery became significantly lower as years wore on.4) Although the period from menarche to menopause tended to get longer, there were no effects of the exercise experienced in youth on it.5) There were no effects of the exercise experienced in youth on the age of menopause and menopausal disorder.

Plasma nitriding treatment is very effective for the hardening of precision metal parts. Especially, high density plasma nitriding can efficiently generate a high density ion with installed hollow cathode, which decreases the damage of the workpiece. As a result, the parts can be cleaned, etched, heated, and nitrided effectively. In this study, an improvement of surface integrity of stainless steel SUS440C is experimentally investigated by nitriding. The experimental analysis made it clear that the surface hardness of workpiece increased due to the generation of nitrided layer even under the low temperature condition like 513K. The nitrided layer was hardened with an increase of process temperature and process time, until a maximum surface hardness of 1700HV.

We have developed a multimedia information system for railroad passengers, that can retrieve graphics and full-color images as well as alphanumeric data. This system consists of a host computer, user terminals, and workstations for creating and editing information pages. These components are linked through a high-speed Ethernet LAN. The user terminals requires high-speed response, so JPEG compression is used in full-color images to reduce the time required to transmit images from the host computer.In September 1993, experimental user terminals were set up in Kintetsu Namba Station, Uehonmachi Station and Abenobashi Station. The tourist information on the Shima Spain Village and Ise-Shima National Park provided by these user terminals has been highly evaluated by users.

The dose of a transdermal fentanyl patch is proportional to its application site area. Therefore, the absorption of fentanyl may decrease if the patch detaches, leading to insufficient analgesia. Sixteen healthy volunteers were enrolled in a study to investigate the appropriate application sites and clinical utility of three transdermal fentanyl patches available in Japan. Three placebos, Fentanyl 1-day (Fentos; Fen), Fentanyl 3-day (Durotep; Dur), and Generic Fentanyl 3-day (HMT) were administered using a crossover study design. The placebos were applied to 11 different sites, including both sides of the upper arm, abdomen, back, thigh, chest, and the middle of the chest. We determined the patch detachment area and incidence of patch-induced itching every 24 h and evaluated differences between each application site using the Wilcoxon signed-rank test. Significant patch detachment was observed on the abdomen and upper arms with Fen, on the abdomen and chest with Dur, and on the chest with HMT compared with that at other sites (p<0.005). Although no significant difference in itching was observed between regions when administering Fen, itching significantly increased on the chest and back when using Dur and on the abdomen when using HMT as compared with that at other sites (p<0.05). Our results indicate that the three transdermal Fen patches exhibit different adhesive properties and local adverse events, indicating that the application site should be cautiously selected for each patch type.

We herein present a rare case of Actinomyces turicensis bacteremia that was caused by pyometra. The patient was successfully treated with transvaginal drainage and antibiotic therapy. A literature review in MEDLINE showed that there have been only 8 previously reported cases of A. turicensis bacteremia. This infection frequently occurs in patients with visceral abscesses, and blood culture examinations usually reveal a polymicrobial pattern. However, the prognosis of such patients has been reported to generally be benign. Due to difficulties in performing bacterial identification and the wide-spectrum clinical pictures associated with this bacteremia, no comprehensive understanding of the clinical features of each Actinomyces species has yet been established.

The author has studied nerve growth factor (NGF) and its family of neurotrophic factors (neurotrophins) for over 40 years. During the first 20 years, my laboratory established a highly sensitive enzyme immunoassay for NGF and analyzed the regulatory mechanism of NGF synthesis in cultured primary cells. Fibroblast cells cultured from peripheral organs such as the heart and astrocytes from the brain produced a substantial amount of NGF in a growth-dependent manner. Furthermore, synthesis of NGF in these cells could be upregulated by catechol compounds including catecholamines. This observation might explain a physiological relation between the level of NGF mRNA and the density of innervation in the peripheral sympathetic nervous systems. Over the subsequent 20 years, my laboratory investigated the physiological functions of neurotrophic factors, including neurotrophins, during development or post-injury and found that brain-derived neurotrophic factor (BDNF) plays a role in the formation of the laminar structure of the cerebral cortex. In addition, my laboratory discovered that endogenous glial cell line-derived neurotrophic factor (GDNF) contributes to the amelioration of motor activity after spinal cord injury. Therefore we aimed to develop low-molecular weight compounds that generate neurotrophic factor-like intracellular signals to protect or ameliorate neurological/psychiatric diseases. 2-Decenoic acid derivatives and other similar molecules could protect or ameliorate in animal models of mood disorders such as depression and enhance recovery from spinal cord injury-induced motor paralysis. Compounds that can generate neurotrophin-like signals in neurons are expected to be developed as therapeutic drugs for certain neurological or psychiatric disorders.
