Abstract
Background/Aims: Gastroprokinetic agents are used for patients with
postoperative ileus (POI), and the Japanese traditional herbal medicine daikenchuto (DKT)
is one such agent used in the clinical setting. POI is caused by inflammation. DKT and
rikkunshito have anti-inflammatory abilities in addition to their gastroprokinetic
effects. The efficacy of Kampo formulations, including hangekobokuto (HKT), in patients
with POI has been reported recently. Several authors have described the efficacy of
honokiol, the primary component of Magnoliae Cortex, in HKT in mouse
models of POI. We therefore analyzed the effect of HKT on POI model mice to determine the
similarities in the mechanism of action between HKT and DKT. Methods: HKT was administered orally to each mouse before and after
intestinal manipulation was performed on the distal ileum. The gastrointestinal transit
in vivo, leukocyte infiltration, and levels of inflammatory mediators,
such as cytokines and chemokines, were analyzed. Results: HKT significantly inhibited the infiltration of neutrophils and
macrophages and led to the recovery of delayed intestinal transit. In addition, it
significantly decreased inducible nitric oxide synthase (iNOS) as well as honokiol levels,
suggesting anti-inflammatory activity. However, it did not inhibit the increase in levels
of interleukin (IL)-1beta and IL-6, which are related to iNOS induction. In contrast, HKT
increased levels of nerve growth factor (NGF) and suppressed those of nuclear factor-κB
(NFκB), which are related to iNOS induction, suggesting the possibility of a neuronal
anti-inflammatory mechanism. Conclusions: HKT exerted a POI-relieving effect similar to DKT in a murine
POI model, and findings suggest that it may exert its anti-inflammatory activity through
NGF.

Abstract
Upper gastrointestinal (GI) motility is affected by various drugs and diseases. However, changes in upper GI motility during these conditions are not well understood, as there are few quantitative in vivo methods that assess small intestinal motility in mice. Ultrasonography is a noninvasive method for imaging and evaluating the condition of the abdominal organs. The aim of the present study was to establish a novel method for evaluating small intestinal motility by using ultrasonography in mice. We measured GI motility with and without loperamide, an antidiarrheal medication, by intestinal transit using an orally administered dye, a 13C-octanoic acid breath test, and ultrasonography. Locomotion activity of the duodenal wall was used for quantifying the GI motility observed via ultrasonography. Our results showed that upper GI transit was significantly delayed by loperamide. The 13C-octanoic acid breath test revealed decreased gastric emptying in loperamide-treated mice. Through ultrasonography, large peristaltic movements were observed in the duodenum of the control mice. In contrast, after treatment with loperamide, these peristaltic movements were suppressed, and the duodenal lumen was enlarged, suggesting decreased duodenal motility. In accordance with these results, quantifiable locomotion activity was also significantly decreased. In conclusion, ultrasonography is an effective in vivo method to quantify small intestinal motility in mice.

Abstract
Zingiberis processum rhizoma (ZPR) is a major active component of daikenchuto (DKT), which induces anti-inflammatory action by inhibiting macrophage infiltration. However, it is unclear whether ZPR is related to DKT-induced anti-inflammatory action via a reduction of neutrophil infiltration against postoperative ileus (POI). In this study, we orally administered individual herbal components of DKT to mice four times before and after intestinal manipulation (IM). The anti-inflammatory action of each crude drug was evaluated by histochemical analysis of relevant molecules. The results showed that treatment with all herbal components of DKT significantly inhibits neutrophil infiltration. This inhibition of neutrophil infiltration by ZPR was significantly reduced in 5-hydroxytryptamine receptor 4 (5-HT4R) knockout (KO) mice but not in alpha-7 nicotinic acetylcholine receptor (α7nAChR) KO mice. Also, transient receptor potential ankyrin 1 (TRPA1) and muscarinic acetylcholine receptor (mAChR) antagonists partly and significantly inhibited the amelioration of neutrophil infiltration by ZPR. Therefore, DKT-induced anti-inflammatory action, mediated by inhibition of neutrophil infiltration in POI, depends, in part, on the effects of ZPR. ZPR activates TRPA1 channels, possibly in enterochromaffin (EC) cells, to release 5-HT. This 5-HT stimulates 5-HT4R in the myenteric plexus neurons to release acetylcholine, which, in turn, activates mAChR to inhibit inflammation in POI.

Abstract
BACKGROUND We previously reported that Daikenchuto (DKT), a gastrointestinal prokinetic Japanese herbal (Kampo) medicine used for the treatment of postoperative ileus (POI), has characteristic potent anti-inflammatory activity. This effect may be partly mediated by the activation of α7 nicotinic acetylcholine receptor (nAChR). In this study, we identified the specific herbs in DKT that induce anti-inflammatory action. METHODS The herbal components of DKT were individually administered orally to each mouse four times before and after intestinal manipulation (IM) was carried out on the distal ileum. The anti-inflammatory activity of each crude drug was subsequently evaluated using immunohistochemical analyses of relevant molecules. KEY RESULTS Treatment with Zingiberis Siccatum Rhizoma (ZSR) but not the other components inhibited the infiltration of cluster of differentiation 68 (CD68)-positive macrophages as effectively as DKT treatment. Selective α7nAChR antagonists, such as methyllycaconitine citrate, or transient receptor potential ankyrin 1 (TRPA1) antagonists, such as HC-030031, significantly inhibited the amelioration of macrophage infiltration by ZSR. The inhibition of macrophage infiltration by ZSR was abolished in both α7nAChR and 5-hydroxytryptamine 4 receptor (5-HT4 R) knockout mice. CONCLUSIONS & INFERENCES Daikenchuto-induced anti-inflammatory activity, which was mediated by inhibiting macrophage infiltration in POI, is dependent on the effects of ZSR. Zingiberis Siccatum Rhizoma activates TRPA1 channels possibly in enterochromaffin (EC) cells to release 5-HT, which stimulates 5-HT4 R in the myenteric plexus neurons to release ACh, which in turn activates α7nAChR on macrophages to inhibit inflammation in POI.

Abstract
Background Kososan, a Kampo (traditional Japanese herbal) medicine, has been used for the therapy of depressive mood in humans. However, evidence for the antidepressant efficacy of kososan and potential mechanisms are lacking. Recently, it has been recognized that stress triggers neuroinflammation and suppresses adult neurogenesis, leading to depression and anxiety. Here, we examined whether kososan extract affected social behavior in mice exposed to chronic social defeat stress (CSDS), an animal model of prolonged psychosocial stress, and neuroinflammation induced by CSDS. Methods In the CSDS paradigm, C57BL/6J mice were exposed to 10 min of social defeat stress from an aggressive CD-1 mouse for 10 consecutive days (days 1–10). Kososan extract (1.0 g/kg) was administered orally once daily for 12 days (days 1–12). On day 11, the social avoidance test was performed to examine depressive- and anxious-like behaviors. To characterize the impacts of kososan on neuroinflammation and adult neurogenesis, immunochemical analyses and ex vivo microglial stimulation assay with lipopolysaccharide (LPS) were performed on days 13–15. Results Oral administration of kososan extract alleviated social avoidance, depression- and anxiety-like behaviors, caused by CSDS exposure. CSDS exposure resulted in neuroinflammation, as indicated by the increased accumulation of microglia, the resident immune cells of the brain, and their activation in the hippocampus, which was reversed to normal levels by treatment with kososan extract. Additionally, in ex vivo studies, CSDS exposure potentiated the microglial pro-inflammatory response to a subsequent LPS challenge, an effect that was also blunted by kososan extract treatment. Indeed, the modulatory effect of kososan extract on neuroinflammation appears to be due to a hippocampal increase in an anti-inflammatory phenotype of microglia while sparing an increased pro-inflammatory phenotype of microglia caused by CSDS. Moreover, reduced adult hippocampal neurogenesis in defeated mice was recovered by kososan extract treatment. Conclusions Our findings suggest that kososan extract prevents a social avoidant behavior in socially defeated mice that is partially mediated by the downregulation of hippocampal neuroinflammation, presumably by the relative increased anti-inflammatory microglia and regulation of adult hippocampal neurogenesis. Our present study also provides novel evidence for the beneficial effects of kososan on depression/anxiety and the possible underlying mechanisms.

Abstract
Accelerated release of potassium (K), magnesium (Mg) and phosphorus (P) from surplus activated sludge (SAS) was investigated to develop a new system for the recovery of the elements. Anaerobic cultivation of SAS during 24 h released 78% of K and about 50% of Mg and P from SAS more effectively compared to aerobic cultivation (K: 40%, Mg: 15%, P: 15%). Furthermore, the addition of sodium acetate as an organic carbon source remarkably accelerated the release of K, Mg and P from SAS under anaerobic condition. However, no increase in the maximum release efficiencies was observed. The elements released from SAS could be transferred to separate liquid with the existing mechanical thickener and be recovered as MgKPO4 by some additional process. Furthermore, the removal of the elements from SAS would inhibit the formation of struvite causing the blockage of sludge transport pipe after anaerobic digestion process of thickened sludge.

Abstract
Onset of the cancer mesenchymal program is closely associated with cancer malignancy and drug resistance. Among the different epithelial–mesenchymal transition (EMT)-associated transcriptional factors, ZEB1 has a key role in inducing the mesenchymal phenotypes and stem cell-like properties of different breast cancer cells. ARF6 and its effector AMAP1 are frequently overexpressed in breast cancer cells, and promote invasion, metastasis and drug resistance. EPB41L5 is induced during EMT, and mediates the disruption of E-cadherin-based cell–cell adhesion and the promotion of focal adhesion dynamics. Here we show that EPB41L5 is an integral component of the ARF6-based pathway, which is induced by ZEB1. We found that EPB41L5 is expressed at high levels in malignant breast cancer cells and binds to AMAP1. ZEB1 induced EPB41L5 both in cancer cells and normal cells. This relationship was recaptured with The Cancer Genome Atlas RNASeq data set, and correlated with the poor outcome of the patients. In contrast, diversified events, such as tumor growth factor β1 stimulation, expression of SNAI1 and TP53 mutation, can each cause the induction of ZEB1 and EPB41L5, depending on the cellular context. Our results demonstrated that the ZEB1-EPB41L5 axis is at the core of the cancer mesenchymal program that drives ARF6-based invasion, metastasis and drug resistance of significant populations of primary breast cancers, and is tightly correlated with the poor outcomes of patients.

Abstract
To reduce labor for superovulation treatment by twice-daily intramuscular (im) administration of FSH for more than 3 to 4 days, we investigated the superovulatory responses of Japanese Black cows to porcine FSH (pFSH) used as a single subcutaneous (sc) administration at two different doses in two different volumes of saline. In experiment 1, 20 Armour units (AU) of pFSH dissolved in either 10 mL (treatment A; n = 14) or 50 mL (treatment B; n = 14) of saline was administered subcutaneously in the neck region. In experiment 2, 30 AU of pFSH dissolved in either 10 mL (treatment C; n = 15) or 50 mL (treatment D; n = 15) of saline was administered subcutaneously in the neck region. The control animals in experiment 1 (n = 14) and experiment 2 (n = 15) received 20 AU of pFSH administered intramuscularly twice daily in decreasing doses for more than 3 days. In experiment 1, mean (±SEM) numbers of CL (15.4 ± 2.5, 18.1 ± 3.4, and 17.2 ± 2.6), total number of ova and embryos (12.9 ± 1.4, 15.9 ± 3.5, and 16.2 ± 2.8), and transferable embryos (7.5 ± 2.0, 10.4 ± 2.8, and 8.0 ± 2.1) did not differ among treatments A, B, and control. In experiment 2, mean (±SEM) numbers of CL (20.5 ± 4.3, 20.4 ± 2.7, and 20.1 ± 3.4), total number of ova and embryos (21.7 ± 4.2, 17.3 ± 3.4, and 16.5 ± 3.2), and transferable embryos (8.1 ± 1.6, 9.3 ± 2.2, and 9.5 ± 1.9) did not differ among treatments C, D, and control. Although there were no differences in serum pFSH concentrations among the three treatments at each of the time points in experiment 1, in experiment 2, the serum pFSH concentration at 6 and 8 hours after pFSH administration in treatment C (3.1 ± 0.8, 2.7 ± 0.5 ng/mL, mean ± SEM) was significantly greater (P < 0.05) than in the control (0.7 ± 0.1, 1.1 ± 0.2 ng/mL). At 10 hours after administration, the pFSH concentration had decreased and there were no differences among the three treatments at subsequent time points. These results suggest that increasing the volume of saline or the dose of pFSH does not affect the absorption pattern of pFSH administered as a single sc administration. In conclusions, single sc administration of pFSH at a dose of 20 or 30 AU dissolved in 10 or 50 mL of saline is able to induce a superovulatory response comparable with that obtained by twice-daily im administration in Japanese Black cows.

Abstract
BACKGROUND Daikenchuto (DKT), a gastrointestinal prokinetic Japanese herbal medicine, is prescribed for patients with postoperative ileus (POI) and adhesive bowel obstruction following abdominal surgery. Several mechanisms for the amelioration of POI by DKT have been suggested; however, it has remained unclear whether DKT shows anti-inflammatory effects in POI. In the present study, we investigated the effects of DKT in a mouse POI model and attempted to clarify the detailed mechanisms of action. METHOD Intestinal manipulation (IM) was applied to the distal ileum of mice. DKT was administered orally to the animals 4 times before and after IM. Gastrointestinal transit in vivo, leukocyte infiltration, cytokine mRNA expression and gastrointestinal motility were analyzed. We also investigated the effects of the α7nAChR antagonist methyllycaconitine citrate (MLA) on the DKT-mediated ameliorative action against POI, and we studied the effects of DKT on inflammatory activity in α7nAChR knockout mice. RESULTS DKT treatment led to recovery of the delayed intestinal transit induced by IM. DKT significantly inhibited the infiltration of neutrophils and CD68-positive macrophages, and inhibited mRNA expressions of TNF-α and MCP-1. MLA significantly reduced the anti-inflammatory action of DKT, and the amelioration of macrophage infiltration by DKT was partially suppressed in α7nAChR knockout mice. CONCLUSIONS In conclusion, in addition to the gastrointestinal prokinetic action, DKT serves as a novel therapeutic agent for POI characterized by its anti-inflammatory potency. The DKT-induced anti-inflammatory activity may be partly mediated by activation of α7nAChR.

Abstract
Our objective was to evaluate the temporal evolution of mercury exposure in two riverside communities, Barreiras and São Luiz do Tapajós, downstream of gold mining areas in the Tapajós basin, Brazilian Amazon. The quantification of mercury in hair sample was made by atomic absorption spectrophotometry in the period between 1994 and 2010. In São Luiz do Tapajós the mercury exposure varied, in log units, from the peak of 1.21 ± 0.03 μg/g in 1996 to 1.16 ± 0.07 μg/g in 2007. Mercury exposure in Barreiras varied, in log units, from 1.25 ± 0.04 μg/g in 1994 to 1 ± 0.03 μg/g in 2010, peaking in 1995 at 1.25 ± 0.06 μg/g. Total mercury concentration found in both communities had no statistical differences across the years (p > 0.05) and they were higher than non-mercury exposed communities in Brazil and in South America. We concluded that the mercury exposure in the Tapajós basin is more than regulatory levels or higher than the general population.

Abstract
Perillae Herba (a leaf of Perilla frutescens) has been prescribed as one of the component herbs in certain Kampo (Japanese herbal) medicines that are used clinically for the improvement of depressive mood. l-Perillaldehyde (PAH) is a major component in the essential oil containing in Perillae Herba, but its antidepressant-like effect has not been reported. To clarify the antidepressant-like effect of PAH, the inhaled effect of PAH on stress-induced depression-like model mice prepared by subjection to a combination of forced swimming and chronic mild stresses was investigated. The degree of the depression-like state was measured by the animal's duration of immobility using a forced swimming test. Inhalation of PAH (0.0965 and 0.965 mg/mouse/day, 9 days) significantly shortened the duration of immobility of the depression-like model mice and did not affect locomotor activity. However, another odor substance, cinnamaldehyde containing in Cinnamomi Cortex, exhibited no reduction in the immobility. The reduction in the immobility induced by the inhalation of PAH was prevented on anosmia-induced mice prepared by intranasal irrigation with zinc sulfate. These results suggest that the inhalation of PAH shows antidepressant-like activity through the olfactory nervous function.

Abstract
The objective of this study was to evaluate the superovulatory response to a single SC administration of pFSH (Antrin R-10) dissolved in saline in Japanese Black cattle. Forty Japanese Black cows were divided into 5 groups. All cows received a progesterone releasing intravaginal device (PRID) at a random stage of the oestrous cycle except the day of oestrus (Day 0). Superovulatory treatments were initiated on Day 4 with single SC administration of 20 AU pFSH dissolved in 10 mL of saline (Group A) or 50 mL of saline (Group B), or 30 AU pFSH dissolved in 10 mL of saline (Group C) or 50 mL of saline (Group D). Conventional superovulatory treatment (Group E) was also initiated on Day 4 with 20 AU pFSH in decreasing doses in IM administration twice a day for 3 days (5/5, 3/3, and 2/2 in the am/pm). Each administration was carried out in the neck region. For oestrus induction, all animals were treated with prostaglandin F2α (750 μg of cloprostenol) on Day 4, and then the PRID was removed on Day 6 in the morning. The GnRH (10 μg of buserelin) was administrated at 31 h after PRID removal to induce ovulations. The cows were artificially inseminated at 24 h after GnRH treatment, and embryos were recovered 7 days after the insemination. Blood samples were collected at 0, 2, 4, 6, 8, 10, 24, 31, 48, 55, 72, and 79 h after the first pFSH administration, and serum pFSH concentration was measured using time-resolved fluorescence immunoassay. Percentage data were arcsine transformed before analysis, and one-way ANOVA was used for statistical analysis (P < 0.05). There were no significant (P > 0.05) differences among groups in the number of corpus luteum, total number of ova/embryos, number of transferable embryos, and percentage of transferable embryos. The concentrations of pFSH in serum increased in all groups 2 h after each administration and reached a peak at 8 h in Groups A and C, at 10 h in Groups B, D, and E, and then in all groups it decreased gradually. The concentrations of pFSH in serum decreased to the base level (the level at 0 h) in Group A at 55 h and in Group C at 72 h after the first pFSH administration. At 79 h, serum pFSH was still detected in Groups B, D, and E. These results suggest that the single SC administration of 20 AU pFSH that is the same dose as the conventional treatment is able to induce a superovulatory response comparable to that of conventional treatment in Japanese Black cattle.

Abstract
Ostwald ripening has been broadly studied because it plays a determinant role in the evolution of cluster size during both chemical and physical synthesis of nanoparticles. This thermoactivated process causes large particles to grow, drawing material from the smaller particles, which shrink. However, this phenomenon becomes more complex when considering the coarsening of metallic alloy clusters. The present experimental and theoretical investigations show that the relative composition of CoPt nanoparticles can be strongly modified during high temperature annealing and displays a size-dependent behavior. This compositional change originates from the higher evaporation rate of Co atoms from the nanoparticles. More importantly, this effect is expected in all alloy clusters containing species with different mobilities.

Abstract
BACKGROUND Saireito consists of components of shosaikoto and goreisan. There are several reports of liver injury caused by shosaikoto and saireito, whereas cases caused by goreisan are rarely seen. PATIENT A 70-year-old woman suffered from sicca of the eyes and oral cavity that arose in 2003. In June 2004, we diagnosed her as having Sjögren syndrome on the basis of Schirmer's test, salivary scintigraphy, presence of anti-SS-A/Ro antibody, and subjective symptoms. Although a muscarinic agonist was commenced, her sicca symptoms did not improve. INTERVENTIONS In February 2008, 7.5 g/day of shosaikoto extract granules (for ethical use, Tsumura & Co., Tokyo, Japan) was introduced. Her symptoms and laboratory data did not change. The next month, the treatment was replaced by 9.0 g/day of saireito extract granules (for ethical use, Tsumura & Co., Tokyo, Japan). RESULTS After 10 weeks, elevation of liver enzymes was observed. On suspicion of drug-induced liver injury (DILI), saireito was withdrawn, and the patient's liver enzymes returned to normal the next month. Drug-induced lymphocyte stimulation tests (DLSTs) for saireito, shosaikoto, and goreisan were all positive. CONCLUSIONS The clinical course suggested allergy to the goreisan component of saireito. It is important to be aware of the limitation of DLST as a diagnostic tool for DILI, especially for herbal medicines.

Abstract
Kososan, a Kampo (Japanese herbal) medicine, has an antidepressive-like effect in behavioral animal models of depression and has been used clinically for the improvement of depressive mood. However, mechanism(s) underlying the antidepressive-like effect of kososan remain unknown. Previous studies showed that orexin-A (OX-A), a neuropeptide that is involved in feeding and arousal, exhibits an antidepressive-like property via hippocampal cell proliferation. Here, we used immunohistochemical analysis with bromodeoxyuridine (BrdU), a marker of proliferating cells, to investigate the effect of long-term treatment with kososan on the orexinergic system and on hippocampal cell proliferation. Oral administration of kososan (1.0 g/kg) or milnacipran (60 mg/kg), a serotonin and noradrenaline reuptake inhibitor, for 28 d led to an antidepressive-like effect in the stress-induced depression-like model mice and reversed the stress-induced decrease in the number of OX-A-positive cells in the lateral hypothalamic area. In addition, both kososan and milnacipran alleviated the stress-induced decrease in the number of BrdU-positive cells in the hippocampal dentate gyrus. Moreover, the antidepressive-like effect and the increase in cell proliferation and in the number of neuropeptide Y (NPY, which is closely associated with orexinergic system)-positive cells in the dentate gyrus induced by kososan were blocked by treatment with SB-334867, an orexin receptor 1 antagonist. These results suggest that kososan exerts an antidepressive-like effect via the improvement of the stress-induced decrease in hippocampal cell proliferation and that the mechanism underlying the antidepressive-like effect of kososan, but not of milnacipran, may be associated with the regulation of orexinergic and/or NPYergic transmission.

Abstract
Chemically ordered bimetallic nanoparticles are promising candidates for magnetic-storage applications. However, the use of sub-10 nm nanomagnets requires further study of possible size effects on their physical properties. Here, the effects of size and morphology on the order-disorder phase transition temperature of CoPt nanoparticles (T(C)(NP)) have been investigated experimentally, using transmission electron microscopy, and theoretically, with canonical Monte Carlo simulations. For 2.4-3-nm particles, T(C)(NP) is found to be 325-175 degrees C lower than the bulk material transition temperature, consistent with our Monte Carlo simulations. Furthermore, we establish that T(C)(NP) is also sensitive to the shape of the nanoparticles, because only one dimension of the particle (that is, in-plane size or thickness) smaller than 3 nm is sufficient to induce a considerable depression of T(C)(NP). This work emphasizes the necessity of taking into account the three-dimensional morphology of nano-objects to understand and control their structural properties.

Abstract
The objective of this study was to find optimal traits for inclusion in selection criteria by estimating genetic parameters for direct genetic, maternal genetic, and common environmental effects for growth traits before 60 d of age and for the number of teats under an open breeding population, and to evaluate genetic relationships for traits at 60 d of age. Records of 2,344 male and 2,204 female purebred Berkshire pigs were analyzed. For BW at 14 d of age and for weaning weight, the heritabilities of a direct genetic effect were greater than those of a maternal genetic effect. This result is contrary to previous results showing a gradual decrease in the maternal genetic effect and an increase in the direct genetic effect up to weaning. The positive genetic correlations between direct and maternal genetic effects for BW at 14 d of age and weaning weight are clearly contrary to other reports. This phenomenon seems to be caused by creep feeding begun just after the birth of the piglets and maintained throughout the preweaning period in this Berkshire population.

Abstract
Although abdominal bloating is one of the most bothersome symptoms experienced by patients with functional dyspepsia (FD), therapeutic drugs to relieve abdominal bloating have not been established. We investigated the Kampo (Chinese herbal) medicine, Hangekobokuto (Banxia-houpo-tang, HKT) for patients with FD from the standpoint of bowel gas retention. The bowel gas volume calculated from a plain abdominal radiogram (gas volume score, GVS) in FD patients was significantly higher than that in healthy subjects. Two week administration of HKT in the FD patients showed a significant decrease of GVS. Furthermore, gastrointestinal symptoms, especially symptoms of abdominal pain, indigestion and constipation, all of which are closely related to abdominal bloating, improved significantly in FD patients after the administration of HKT. These results suggest that HKT improves abdominal bloating accompanied by the reduction of bowel gas in FD patients.

Abstract
AIMS To determine the sensitivity and specificity of the photopic negative response (PhNR) of the focal electroretinograms (ERG; focal PhNR) to detect glaucomatous eyes with different degrees of visual field defects. METHODS One-hundred and fourteen eyes of 114 patients with open angle glaucoma and 42 eyes of 42 normal controls were studied. The focal ERGs were elicited by a 15 degrees stimulus spot centred on the macula, and on the supero-temporal and on the infero-temporal areas of the macula. The receiver operating characteristic curves were determined to obtain optimal cut-off values. Eyes were classified as being glaucomatous when their focal PhNRs were less than the cut-off values in either retinal area (combined criterion). RESULTS The focal PhNR amplitudes were significantly reduced with an advance in the stage of glaucoma. In early glaucoma, the sensitivities of the PhNR measured for each retinal area ranged from 58.1% to 80.7%. The sensitivities were significantly increased to 90.6% and 96.9% for the focal PhNR amplitude and the focal PhNR/b-wave amplitude ratio, respectively, when the combined criterion was employed. The specificity was >90%. CONCLUSIONS Focal PhNRs have diagnostic ability in detecting early glaucoma with high sensitivity and specificity, especially when the combined criterion is used.

Abstract
In clinical and experimental settings, the (13)C breath test is performed to measure gastric emptying and has advantages of noninvasiveness and repeatability. We intended to apply the (13)C breath test method to mice with an easy-to-handle solid test meal that is more physiological than liquid meals. Male ddY mice were trained to eat (13)C-acetate-containing pellets as the solid test meal. Thirty minutes after administration of metoclopramide (0.3-3 mg/kg, p.o.) or atropine sulfate (0.3-3 mg/kg, i.p.), mice received the test meal and were placed in chambers. The (13)CO(2) levels in the expired air were measured and the maximum concentration (C(max); per thousand) and the time to reach the maximum concentration (T(max); min) were determined. Metoclopramide significantly and dose-dependently increased C(max) and decreased T(max). On the other hand, atropine sulfate significantly and dose-dependently decreased C(max) and increased T(max). The (13)C-acetate breath test using a solid test meal is sensitive enough to detect both enhanced and delayed gastric emptying of the reference drugs.

Abstract
The objective of this study was to estimate genetic parameters for growth and body composition traits at 60 d of age and at finish in a population of Berkshire pigs and to evaluate the effectiveness of selection at 60 d of age for meat productivity. A total of 4,548 purebred Berkshire (2,344 males and 2,204 females) pigs born between December 1994 and January 2005 were used in this study. The traits analyzed were BW at 60 d of age; daily BW gain from birth to finish, from weaning to 60 d, from weaning to finish, and from 60 d to finish; age at finish; backfat thickness at 60 d of age and at finish; loin eye area at 60 d of age (LEA60) and at finish; and the number of teats. The heritability estimates for BW at 60 d of age, daily BW gain from weaning to 60 d, backfat thickness at 60 d of age, and LEA60 were 0.22, 0.25, 0.49, and 0.22, respectively. The estimated common environmental effect for BW at 60 d of age, daily BW gain from weaning to 60 d, backfat thickness at 60 d of age, and LEA60 were 0.12, 0.13, 0.18, and 0.21, respectively. Therefore, the common environmental effect should be included in the model to analyze traits at 60 d of age. The positive genetic correlation between LEA60 and loin eye area at finish and the negative genetic correlation between LEA60 and backfat thickness at finish indicated that improvement of the ultrasonic loin eye area at 60 d of age may result in favorable correlated responses to the traits at finish, an increase in loin eye area, and a decrease in backfat thickness. In addition, genetic correlations of backfat thickness at 60 d of age with backfat thickness at finish and loin eye area at finish were found to be favorable, indicating that improvement of ultrasonic backfat thickness at 60 d of age may result in greater correlated responses to the traits at finish: an increase in loin eye area and a decrease in backfat thickness. Therefore, constructing a selection scheme that includes body composition traits at 60 d and traits at finish is practical for gaining a greater selection response.
