Abstract
The invariant differential cross section for inclusive neutral-pion production in p+p collisions at sqrt[s]=200 GeV has been measured at midrapidity (|eta|<0.35) over the range 1<p(T) less, similar 14 GeV/c by the PHENIX experiment at the Relativistic Heavy Ion Collider. Predictions of next-to-leading order perturbative QCD calculations are consistent with these measurements. The precision of our result is sufficient to differentiate between prevailing gluon-to-pion fragmentation functions.

Abstract
We report evidence for the decay mode B-->phiphiK based on an analysis of 78 fb(-1) of data collected with the Belle detector at KEKB. This is the first example of a b-->sssss transition. The branching fraction for this decay is measured to be B(B+/--->phiphiK+/-)=(2.6(+1.1)(-0.9)+/-0.3)x10(-6) for a phiphi invariant mass below 2.85 GeV/c(2). Results for other related charmonium decay modes are also reported.

Abstract
The topography and the course of the facial artery were investigated in 47 Korean cadavers. The final branch of the facial artery was the lateral nasal branch in 44.0% whereas it was the angular branch in 36.3% of the cases. In 54.5% of the cases, the facial artery ended symmetrically. According to previous studies, variations in the distribution pattern of the facial artery have been regarded as racial difference. However, in this study we showed that the diverse pattern of the facial artery distribution demonstrates individual variation rather than racial difference. The superior and inferior labial arteries on the right side were more dominant than those on the left. The average distance between the branching points for the inferior alar branch and for the lateral nasal branch was 15.9 mm, and it was 25.2 mm between the points for the superior labial branch and for the inferior alar branch. The branching point of the inferior labial branch was 30.9 mm apart on average from that of the superior labial branch. The courses of the facial arteries showed no significant differences based on either laterality or gender.

Abstract
A solitary plasmacytoma occurring in the mandible of a 15-year-old Korean male 6 years after renal transplantation is reported. The tumour presented as a hyperplastic gingival overgrowth in the right madibular molar area. Histology and immunohistochemistry revealed plasmacytoma and monoclonality of the kappa chain and IgG. In situ hybridization for Epstein-Barr virus encoded RNA (EBER) showed positive signals in the tumour cells. The tumour regressed after reducing the immunosuppressive agents with concurrent radiotherapy. The patient remains in a stable condition with normal renal functions after 7 years without recurrence. This case confirms that Epstein-Barr virus associated B-lymphoproliferative disorders are still a major complication of immunosuppression.

Abstract
Commonly, the nerve branches from the anterior mandibular nerve trunk pass between the roof of infratemporal fossa and the superior head of lateral pterygoid. However, varied courses of the mandibular nerve branches can be frequently observed. The purpose of this study was to clarify the positional relationships and the clinical relevance of the course variations of the branches of the anterior mandibular nerve trunk with reference to the surrounding anatomical structures. Thirty-six hemi-sectioned heads were studied in detail. In 20 cases, the posterior deep temporal nerve had a common trunk with the masseteric nerve and was then divided anteriorly (15 cases) or posteriorly (five cases). In 16 cases, the posterior deep temporal nerve arose from the mandibular nerve trunk independently. Based on the branching patterns of the middle deep temporal nerve, type A (one twig of the middle deep temporal nerve) was most frequent and occurred in 41.7%. Similarly, type B (two twigs), type C (three twigs) and type D (four twigs) were observed in 36.1%, 16.7%, and 5.5%, respectively. The twigs of the middle deep temporal nerve, which pierced the muscle fibers of the superior head of lateral pterygoid, were found in 21 cases (58.3%). Cases in which the middle deep temporal nerve pierced through all areas of the superior head were most frequent (56.5%). These results suggest that the piercing patterns of the middle deep temporal nerve show there is a possibility that it may be compressed during the actions of the superior head of lateral pterygoid.

Abstract
FK506 is a newly developed potent immunosuppressant for preventing rejection after organ transplantation. However, FK506 can induce central nervous system toxicity. Until now the pathogenic mechanism of FK506 neurotoxicity was unclear. We report the findings of diffusion-weighted MRI and apparent diffusion coefficient (ADC) mapping of a FK506 neurotoxicity patient who showed increased signal intensities in both parieto-occipital lobes on T(2) weighted images, diffusion-weighted images and ADC maps. These findings suggest that a vasogenic oedema rather than a cytotoxic oedema may play a pivotal role in FK506 neurotoxicity pathogenesis.

Abstract
BACKGROUND AND AIMS Preliminary studies have shown that naringin has a potent lipid-lowering effect and antioxidant capacity in high-cholesterol diet fed animals. Accordingly, the present study was conducted to investigate the effect of naringin on hypercholesterolemic subjects. METHODS A hypercholesterolemic group (n=30) and healthy control group (n=30) were established based on the plasma cholesterol levels in the subjects, then all subjects received naringin (400mg/capsule/day) with regular meals for a period of 8 weeks. RESULTS In the hypercholesterolemic subjects, naringin supplementation was found to lower the plasma total cholesterol by 14% and low-density lipoprotein cholesterol concentrations by 17%, while the plasma triglyceride and high-density lipoprotein cholesterol concentrations remained unaffected. The apolipoprotein B levels in the hypercholesterolemic subjects were significantly lowered after naringin treatment, yet no change was observed in the apolipoprotein A-1 levels. The erythrocyte superoxide dismutase and catalase activities in the hypercholesterolemic group were significantly increased, whereas the glutathione peroxidase activity and plasma TBARS levels were not different from the baseline measurements. Meanwhile, naringin supplementation had no affect on plasma lipids, apolipoproteins, and TBARS levels or antioxidant enzyme activities in the control group. CONCLUSIONS Therefore, these data suggest that naringin may play an important role in lowering plasma cholesterol and regulating the antioxidant capacity in hypercholesterolemic subjects.

Abstract
We report the first observation of the charmless vector-vector decay process B-/+-->rho(-/+)rho(0). The measurement uses a 78 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric e(+)e(-) collider operating at the Upsilon(4S) resonance. We obtain a branching fraction of B(B-/+-->rho(-/+)rho(0))=[31.7+/-7.1(stat)+3.8-6.7(syst)]x10(-6). An analysis of the rho helicity-angle distributions gives a longitudinal polarization fraction of Gamma(L)/Gamma=0.95+/-0.11(stat)+/-0.02(syst). We also measure the direct-CP-violating asymmetry A(CP)(B-/+-->rho(-/+)rho(0))=0.00+/-0.22(stat)+/-0.03(syst).

Abstract
STUDY DESIGN Case report OBJECTIVE To examine the resolution of holocord myelopathy based on the hypothesis of altered cerebrospinal fluid (CSF) dynamics. SETTING Seoul National University Hospital, Seoul, Korea. METHOD We describe a case of thoracic stenosis with holocord myelopathy, which suggests an alternative mechanism for the myelopathy. RESULT Decompression of the thoracic stenosis resulted in the resolution of holocord myelopathy. CONCLUSION Myelopathy may be caused by altered CSF dynamics and this type of myelopathy seems to be interstitial edema. Improvement of altered CSF flow dynamics could resolve this type of myelopathy.

Abstract
Acupuncture is useful in treating the nausea and vomiting related to chemotherapy, adult postoperative surgery pain and postoperative dental pain. We obtained single-photon emission computed tomography (SPECT) brain perfusion images of six patients with middle cerebral artery occlusion obtained before and after acupuncture and compared the changes in regional cerebral blood flow (rCBF) to those in normal control. Images were obtained before and after acupuncture at six traditional acupoints (LI 4, 10, 11, 15 and 16 and TE5) in the affected arm. The baseline image was subtracted from the postacupuncture image, to produce a subtraction image displaying only voxels with values >2 SD from the mean and those voxels were coregistered to the baseline SPECT or T2-weighted MRI. Similar images were obtained before and after acupuncture of eight normal volunteers. Statistical parametric mapping with a threshold of P =0.001 and a corrected P of 0.05 was performed for group comparison between postacupuncture and baseline SPECT. Focally increased CBF was seen in all patients especially in the hypoperfused zone surrounding the ischaemic lesion, the ipsilateral or contralateral sensorimotor area, or both. Normal subjects showed increased rCBF mainly in the parahippocampal gyrus, premotor area, frontal and temporal areas bilaterally and ipsilateral globus pallidus. Acupuncture stimulation after stroke patients appears to activate perilesional or use-dependent reorganised sites and might be a way of looking at brain reorganisation.

Abstract
The anisotropy parameter (v(2)), the second harmonic of the azimuthal particle distribution, has been measured with the PHENIX detector in Au+Au collisions at sqrt[s(NN)]=200 GeV for identified and inclusive charged particle production at central rapidities (|eta|<0.35) with respect to the reaction plane defined at high rapidities (|eta|=3-4 ). We observe that the v(2) of mesons falls below that of (anti)baryons for p(T)>2 GeV/c, in marked contrast to the predictions of a hydrodynamical model. A quark-coalescence model is also investigated.

Abstract
We report on the yield of protons and antiprotons, as a function of centrality and transverse momentum, in Au+Au collisions at sqrt[s(NN)]=200 GeV measured at midrapidity by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider. In central collisions at intermediate transverse momenta (1.5<p(T)<4.5 GeV/c) a significant fraction of all produced particles are protons and antiprotons. They show a centrality-scaling behavior different from that of pions. The pmacr;/pi and p/pi ratios are enhanced compared to peripheral Au+Au, p+p, and e(+)e(-) collisions. This enhancement is limited to p(T)<5 GeV/c as deduced from the ratio of charged hadrons to pi(0) measured in the range 1.5<p(T)<9 GeV/c.

Abstract
In order to validate the use of the stem bark of Catalpa ovata G. Don. (Bignoniaceae) as an anti-inflammatory drug in the traditional Korean medicine, we have investigated the effects of the methanol extract of this folk medicine on the productions of tumor necrosis factor-alpha (TNF-alpha) and nitric oxide (NO) on RAW 264.7 macrophages activated with the endotoxin lipopolysaccharide. The extract inhibited the productions of TNF-alpha and NO with significant decreases in mRNA levels of TNF-alpha and inducible NO synthase, suggesting that the stem bark of Catalpa ovata may have therapeutic potential in the control of inflammatory disorders.

Abstract
Transverse momentum spectra of charged hadrons with p(T)<8 GeV/c and neutral pions with p(T)<10 GeV/c have been measured at midrapidity by the PHENIX experiment at BNL RHIC in d+Au collisions at sqrt[s(NN)]=200 GeV. The measured yields are compared to those in p+p collisions at the same sqrt[s(NN)] scaled up by the number of underlying nucleon-nucleon collisions in d+Au. The yield ratio does not show the suppression observed in central Au+Au collisions at RHIC. Instead, there is a small enhancement in the yield of high momentum particles.

Abstract
Transverse momentum spectra of neutral pions in the range 1<p(T)<10 GeV/c have been measured at midrapidity by the PHENIX experiment at BNL RHIC in Au+Au collisions at sqrt[s(NN)]=200 GeV. The pi(0) multiplicity in central reactions is significantly below the yields measured at the same sqrt[s(NN)] in peripheral Au+Au and p+p reactions scaled by the number of nucleon-nucleon collisions. For the most central bin, the suppression factor is approximately 2.5 at p(T)=2 GeV/c and increases to approximately 4-5 at p(T) approximately 4 GeV/c. At larger p(T), the suppression remains constant within errors. The deficit is already apparent in semiperipheral reactions and increases smoothly with centrality.

Abstract
The blood partition of KR-31378 between plasma and blood cells and the factors influencing the binding of the drug to 4% human serum albumin (HSA) using an equilibrium dialysis technique were evaluated. KR-31378 reached an equilibrium rapidly between plasma and blood cells of rabbit blood. The equilibrium plasma/blood cells concentration ratios were independent of initial rabbit blood concentrations of KR-31378, 1, 10 and 50 microg/ml; the values were in the range of 1.42-2.33. It took approximately 12-h incubation to reach an equilibrium between plasma and isotonic Søresen phosphate buffer of pH 7.4 containing 3% dextran ('the buffer'). The binding of KR-31378 to 4% HSA was dependent on HSA concentrations (the binding values were 25.3 and 32.0% for HSA concentrations of 2 and 5%, respectively), incubation temperature (the binding values were 48.8, 29.0 and 25.8% for 4, 22 and 37 degrees C, respectively), pHs of isotonic Sørensen phosphate buffer containing 3% dextran (the binding values were 17.7, 20.6, 22.8, 25.6 and 29.5% for buffer pHs of 5.8, 6.4, 7.0, 7.4 and 8.0, respectively) and alpha-1-acid glycoprotein (AAG) concentrations (the binding values were 25.6, 29.9, 34.4 and 50.3% for AAG concentrations of 0, 0.08, 0.16 and 0.32%, respectively).

Abstract
The purpose of this study was to evaluate the topography of the nerve distribution on the two heads of the lateral pterygoid and to clarify their morphological-functional correlations. The nerve distribution on the lateral pterygoid was studied in 24 hemi-sectioned heads. Both heads of the lateral pterygoid were innervated from the mandibular nerve branches, but with various nerve distribution patterns. The nerves innervating the superior head of the lateral pterygoid originated from the buccal nerve only in 45.8% of cases. In contrast, the nerves innervating the inferior head of the lateral pterygoid originated from both the buccal and mandibular nerve trunk in 58.3% of cases. In the seven distribution categories of the mandibular nerve branches, both the superior and inferior heads of the lateral pterygoid had a common source of nerve innervation in only 20.8% of cases, the buccal nerve. In contrast, in 45.9% of cases, additional nerve twigs from the mandibular nerve trunk were distributed on the inferior head of the lateral pterygoid. In summary, besides the buccal nerve described in anatomy textbooks, the nerve branches that originated directly from the mandibular nerve trunk innervated the lateral pterygoid.

Abstract
OBJECTIVE To investigate the in vitro effects of dehydroepiandrosterone (DHEA) on human osteoarthritic chondrocytes. DESIGN Chondrocytes isolated from human osteoarthritic knee cartilage were three-dimensionally cultured in alginate beads, except for cell proliferation experiment. Cells were treated with DHEA in the presence or absence of IL-1beta. The effects on chondrocytes were analyzed using a 3-(4,5-dimethylthiazol-2yl)-5-(3-carboxymethoxy-phenyl)-2-(4-sulfophenyl)-2H-tetrazolium inner salt (MTS) assay (for chondrocyte proliferation), a dimethylmethylene blue (DMB) assay (for glycosaminoglycan (GAG) synthesis), and an indole assay (for DNA amount). Gene expressions of type I and II collagen, metalloproteinase-1 and -3 (MMP-1 and -3), and tissue inhibitor of metalloproteinase-1 (TIMP-1) as well as the IL-1beta-induced gene expressions of MMP-1 and -3 were analyzed by reverse transcription-polymerase chain reaction (RT-PCR). The protein synthesis of MMP-1 and -3 and TIMP-1 was determined by Western blotting. RESULTS The treatment of chondrocytes with DHEA did not affect chondrocyte proliferation or GAG synthesis up to 100 micro M of concentration. The gene expression of type II collagen increased in a dose-dependent manner, while that of type I decreased. DHEA suppressed the expression of MMP-1 significantly at concentrations exceeding 50 micro M. The gene expression of MMP-3 was also suppressed, but this was without statistical significance. The expression of TIMP-1 was significantly increased by DHEA at concentrations exceeding 10 micro M. The effects of DHEA on the gene expressions of MMP-1 and -3 were more prominent in the presence of IL-1beta, in which DHEA suppressed not only MMP-1, but also MMP-3 at the lower concentrations, 10 and 50 micro M, respectively. Western blotting results were in agreement with RT-PCR, which indicates that DHEA acts at the gene transcription level. CONCLUSIONS Our study demonstrates that DHEA has no toxic effect on chondrocytes up to 100 micro M of concentration and has an ability to modulate the imbalance between MMPs and TIMP-1 during OA at the transcription level, which suggest that it has a protective role against articular cartilage loss.

Abstract
cDNA clones for two of the yolk proteins, YP1 and YP2, produced by the fat body of the moth, Hyphantria cunea, were sequenced and found to be homologous to the follicular epithelium yolk proteins of pyralid moths. Both cDNA clones coded for polypeptides of 290 residues and the deduced amino acid sequence identity between YP1 and YP2 was very high (79.0%). Analysis of the secondary structure of the predicted polypeptides suggests that YP1 and YP2 do not form heteromeric proteins because of differences in secondary structure due to the lack of alpha helices in YP1. Northern blot analysis showed that the transcripts for YP1 (1.2 kb) and YP2 (1.1 kb) were present primarily in the female fat body with only trace levels detectable in the ovary of the adult female. In a developmental study, the YP1 and YP2 transcripts were first detectable in 10-day-old pupae and increased into the adult stage. These results suggest that the YP1 and YP2 genes in H. cunea have been recruited to replace the vitellogenin gene as the primary source of yolk proteins. During this process they have acquired a modified pattern of expression that is different from homologous genes reported in pyralid moths. The assessment of the evolution of proteinaceous yolk in these moths should serve as an excellent model for the evolution of gene recruitment.

Abstract
The Duopath Verotoxin test (Merck KgaA, Darmstadt, Germany) is a newly developed immunochromatographic test for the confirmation of Shiga toxin (Stx)-producing Escherichia coli (STEC) strains from food products. This test detects both Stx 1 (Stx1)-positive and Stx2-positive samples individually with the same device. By modification of the original protocol, the present study evaluated its performance and feasibility for clinical application with human stool samples, consisting of 41 frozen samples known to contain STEC isolates (O157:H7 and non-O157 serotypes) and 250 fresh specimens. The test specimens were polymyxin B extracts of colony sweeps taken from overnight sorbitol-MacConkey agar cultures of stools containing STEC isolates and other bacteria. All 41 frozen STEC-positive stool samples were positive by the Duopath Verotoxin test, as were 2 fresh stool samples with culture-confirmed STEC O157 infection. Thus, 100% sensitivity and no false-positive results were obtained when the Premier EHEC assay (Meridian Bioscience, Cincinnati, Ohio) was used as the "gold standard." The Duopath Verotoxin test is simple to perform and easy to interpret, providing a turnaround time of 24 h. Despite its original intended use, the Duopath Verotoxin test has a great potential for clinical application.

Abstract
1. The effects of chemical agents on the metabolism of the antihistamine drug astemizole were investigated to evaluate drug-drug interactions. 2. Chemical inhibitors of astemizole O-demethylation were screened using the small intestinal and liver microsomes from rabbit as an animal model for the first-pass metabolism of humans. In the rabbit small intestine, astemizole O-demethylation was clearly inhibited by ebastine, arachidonic acid, alpha-naphthoflavone, ketoconazole, tranylcypromine, troglitazone and terfenadine. 3. In humans, these inhibitors also reduced microsomal astemizole O-demethylation in both the small intestine and liver. However, the inhibition rate of almost all these chemicals were clearly greater in the small intestine than in the liver. Thus, a different contribution of cytochrome p450 in each tissue is suggested. 4. All the chemicals inhibited astemizole O-demethylation in recombinant CYP2J2 microsomes. The results suggest that CYP2J2 is involved in astemizole O-demethylation in both the human small intestine and liver; however, the contribution in the liver is lower than in the small intestine. The effects of the CYP2J2 inhibitors during first-pass metabolism may be more important in the small intestine than in the liver. Since all the inhibition profiles of astemizole O-demethylation were different in the liver and small intestine, involvement of another p450 in astemizole O-demethylation in human liver may be speculated. 5. In the rabbit microsomal systems, the same metabolites found in humans were qualitatively detected and the inhibition profiles of the chemical agents in the microsomes resembled that of humans.

Abstract
We report the first observation of the charmless hyperonic B decay, B0-->pLambda(pi)(-), using a 78 fb(-1) data sample recorded on the Upsilon(4S) resonance with the Belle detector at KEKB. The measured branching fraction is B(B0-->pLambda(pi)(-))=(3.97(+1.00)(-0.80)+/-0.56)x10(-6). Searches for B0-->pLambda(K)- and pSigma(0)pi(-) yield no significant signals and we set 90% confidence-level upper limits of B(B0-->pLambda(K)-)<8.2x10(-7) and B(B0-->pSigma(0)pi(-))<3.8x10(-6).

Abstract
We report on a search for B(0)-->D(*0)K(*0) decays based on 85 x 10(6) BB events collected with the Belle detector at KEKB. The B(0)-->D0K(0) and B(0)-->D0K(*0) decays have been observed for the first time with the branching fractions B(B(0)-->D0K(0))=(5.0(+1.3)(-1.2)+/-0.6)x10(-5) and B(B(0)-->D0K(*0))=(4.8(+1.1)(-1.0)+/-0.5)x10(-5). No significant signal has been found for the B(0)-->D(*0)K*0) and B(0)-->D(*0)K(*0) decay modes, and upper limits at 90% C.L. are presented.
