Abstract
OBJECTIVE The present study aimed to clarify the structural recovery, and to compare the time course of morphological changes in trabeculae and the process of bone mass change in rat tibiae following temporary immobilization of hind limb by sciatic neurectomy or nerve freezing. METHODS In 11-week-old male Fischer 344 rats, 4-5 mm of the sciatic nerve was removed (neurectomy group) or frozen by 5-second application of a stainless steel rod immersed in liquid nitrogen (nerve-freezing group). Quantitative changes in cancellous bone were assessed by histomorphometry. RESULTS The results clarified that: trabecular bone volume (BV/TV) decreases until 3 weeks after denervation, and in the nerve-freezing group, it then increases from week 4, recovering to pre-surgery levels by week 10 (no recovery was seen in the neurectomy group); in the initial phase of bone atrophy, the decrease in BV/TV is more gradual in the nerve-freezing group than in the neurectomy group; and changes in trabecular architecture in the bone atrophy-recovery process are strongly associated with changes in trabecular thickness. CONCLUSION The findings suggested that after transient injury by nerve freezing and subsequent recovery of neuromuscular function, bone tissue undergoes recovery from bone loss, but that trabeculae may not show complete structural recovery.

Abstract
We developed a heat-processing method to enhance the antioxidant activity of koji. The superoxide anion scavenging activity (SOSA) and oxygen radical absorbance capacity (ORAC) of heat-processed koji (HP-koji) at 55 °C for 7 days were 4.9 times and 4.2 times, respectively, those of unheated koji. These results showed that heat processing effectively enhances the antioxidant activity of koji. Analysis of the antioxidant activities of koji subjected to a range of temperatures (45-75 °C) revealed that the SOSA is enhanced by heating at higher temperatures, which might be catalyzed by Maillard reaction, whereas the ORAC was enhanced by heating at lower temperatures, which might be catalyzed by an enzymatic reaction. Assuming these enhancements in antioxidant activities are contributed by both Maillard and enzyme reactions, we hypothesized that the antioxidant activity of HP-koji could be more effectively amplified by heating at a higher temperature after the progression of the enzymatic reaction at a moderate temperature. Therefore, we evaluated the effect of heating of koji in a stepwise manner, first at 55 °C for 2 days and then at 75 °C for 5days. The antioxidant activities of stepwise-heated HP-koji were higher than those of koji heated at either 55 °C or 75 °C. The SOSA and ORAC of stepwise-heated HP-koji were 94 times and 6 times, respectively, those of unheated koji. This result suggests that enzymatic reaction followed by Maillard reaction can effectively enhance the antioxidant activity of HP-koji. Thus, we developed a novel heat-processing method to enhance the antioxidant activity of koji.

Abstract
The intracellular beta-glucosidase from Kluyveromyces marxianus NBRC1777 (KmBglI) belongs to glycoside hydrolase family 3 and has a unique domain architecture. Selenomethionine-labelled KmBglI was purified and crystallized by the hanging-drop vapour-diffusion method using the purified enzyme at 30 mg ml(-1), 0.04 M potassium dihydrogen phosphate pH 5.1, 16%(w/v) PEG 8000 and 20%(v/v) glycerol. The crystal belonged to space group C2, with unitcell parameters a = 245.8, b = 148.7, c = 119.9 angstrom, beta = 112.9 degrees. Multiple-wavelength anomalous dispersion data were collected at 2.4 and 2.5 angstrom resolution. A tetramer was assumed to be present in the asymmetric unit, which gave a Matthews coefficient of 2.6 angstrom(3) Da(-1).

Abstract
AIM There is convergent evidence that exercise increases psychological well-being; however, the mechanism of this psychological effect of exercise is not yet completely understood. The purpose of this study was to examine the effects of aerobic exercise training on brain structure and psychological well-being in young adults. METHODS University students who had not regularly exercised were divided into training group (N.=15) and control group (N.=15). The training group performed a total 30 periods of aerobic exercise training, while the control group never performed. Whole-brain magnetic resonance imaging scans and mental health questionnaire examinations were performed before and after the exercise training period for all of the participants. A voxel-based morphometry (VBM) analysis was used to compare the changes in gray-matter volumes in the two groups. VBM is an objective whole-brain technique for characterization of regional cerebral volume and tissue concentration differences in structural magnetic resonance images. RESULTS The results of VBM analysis revealed no change in gray-matter volume in the training group, although the gray-matter volume of the left insula was significantly decreased in the control group after the exercise training period. The training group exhibited significant improvement in some scores on the mental health questionnaire after the exercise training period, compared with the control group. CONCLUSIONS These findings suggest that aerobic exercise training may inhibit gray-matter volume loss in the insula, and that a relationship may exist between preservation of insula gray-matter and improvement of psychological well-being by aerobic exercise training.

Abstract
BACKGROUND Little is known about long-term outcome of tacrolimus therapy for ulcerative colitis. Aim To evaluate long-term efficacy and safety of tacrolimus in Japanese patients with refractory ulcerative colitis. METHODS Twenty-seven patients with UC refractory to conventional therapy were administered tacrolimus with trough whole-blood levels of 10-15 ng/mL to induce remission and 5-10 ng/mL to maintain remission. Median treatment duration was 11 months (1-39 months) and median follow-up duration was 17 months (2-65 months). Evaluation of the clinical response was based on a modified Truelove-Witts severity index (MTWSI). RESULTS Tacrolimus produced a clinical response in 21 patients (77.8%), and remission was achieved in 19 of these 21 (70.4%) within 30 days. Overall cumulative colectomy-free survival was estimated as 62.3% at 65 months. In 18 of 19 patients treated with corticosteroids at the initiation of tacrolimus therapy, corticosteroids were discontinued or tapered. Adverse events were tremor (25.9%), renal function impairment (18.5%), infectious disease (14.8%), hot flashes (11.1%), hyperkalaemia (7.4%), headache (7.4%), epigastralgia (7.4%) and nausea (3.7%). No mortality occurred. CONCLUSION Long-term administration of tacrolimus appears to be an effective and well-tolerated treatment for Japanese patients with refractory ulcerative colitis.

Abstract
In the yeast Saccharomyces cerevisiae, glucose signals activate the production of cellular cAMP. This signaling pathway is called the cAMP-protein kinase A (PKA) pathway, which plays a major role in the regulation of cell growth, metabolism, and stress resistance. Extensive studies have been carried out to clarify the mechanism of this pathway, and many factors involved in the pathway have been identified such as small G proteins, the GDP-GTP exchange factor, adenylate cyclase, and PKA. Also, additional elements involved in this pathway have been evaluated in the last decade. A heterotrimeric G protein alpha subunit was identified as a mammalian Galpha homologue, and a G-protein-coupled receptor (GPCR), which initiates the signaling pathway in response to glucose addition, was identified. GPCR-Galpha was shown to function in a signaling pathway that acts parallel to small G proteins. These signaling pathways regulate cell growth and differentiation in response to nutrients.

Abstract
Candida albicans is a human fungal pathogen and has been extensively studied because of its clinical importance. Comprehensive gene analyses have, however, made little progress. This is because of the diploid and asexual characteristics of the fungus that hamper gene disruptions. In this study, we found that ultraviolet (UV) irradiation, as well as mutagen treatment, strongly stimulated loss of heterozygosity (LOH) in strains harboring artificially constructed heterozygosity. UV-induced LOH occurred more frequently in cells within the logarithmic phase of growth compared to those within the stationary phase of growth. This was observed at all loci tested on chromosome 7, except for a locus neighboring the centromere. C. albicans RAD52, whose orthologue in Saccharomyces cerevisiae was reported to be involved in DNA repair by homologous recombination, was shown to be required for UV-induced LOH. These results suggest that high efficiency LOH caused by UV irradiation could be a prominent tool for gene analyses in C. albicans.

Abstract
Phospholipids are major components of cellular membranes that participate in a range of cellular processes. Phosphatidic acid (PA) is a key molecule in the phospholipid biosynthetic pathway. In Saccharomyces cerevisiae, SLC1 has been identified as the gene encoding lysophosphatidic acid acyltransferase, which catalyzes PA synthesis. However, despite the importance of PA, disruption of SLC1 does not affect cell viability (Nagiec, M. M., Wells, G. B., Lester, R. L., and Dickson, R. C. (1993) J. Biol. Chem. 268, 22156-22163). We originally aimed to identify the acetyl-CoA:lyso platelet-activating factor acetyltransferase (lysoPAF AT) gene in yeast. Screening of a complete set of yeast deletion clones (4741 homozygous diploid clones) revealed a single mutant strain, YOR175c, with a defect in lysoPAF AT activity. YOR175c has been predicted to be a member of the membrane-bound O-acyltransferase superfamily, and we designated the gene LPT1. An Lpt1-green fluorescent protein fusion protein localized at the endoplasmic reticulum. Other than lysoPAF AT activity, Lpt1 catalyzed acyltransferase activity with a wide variety of lysophospholipids as acceptors, including lysophosphatidic acid, lysophosphatidylcholine, lysophosphatidylethanolamine, lysophosphatidylglycerol, lysophosphatidylinositol, and lysophosphatidylserine. A liquid chromatography-mass spectrometry analysis indicated that lysophosphatidylcholine and lysophosphatidylethanolamine accumulated in the Deltalpt1 mutant strain. Although the Deltalpt1 mutant strain did not show other detectable defects, the Deltalpt1 Deltaslc1 double mutant strain had a synthetic lethal phenotype. These results indicate that, in concert with Slc1, Lpt1 plays a central role in PA biosynthesis, which is essential for cell viability.

Abstract
Kluyveromyces marxianus NBRC1777 was identified as a thermotolerant yeast and was developed as a host for the expression of thermostable cellulase genes. The previously isolated genes for thermostable endo-beta-1,4-glucanase, cellobiohydrolase, and beta-glucosidase were introduced into the chromosome of K. marxianus and successfully expressed under the control of high-expression promoters. The recombinant K. marxianus expressing cellulase genes became able to grow in synthetic medium containing cellobiose or carboxymethyl-cellulose as the single carbon source. Moreover, the recombinant strain produced 43.4 g/L ethanol from 10% cellobiose. These results suggest that K. marxianus may afford a useful host system, which may be applicable to the simultaneous saccharification and fermentation and the foundation of cellulose consolidated bioprocessing.
