Abstract
Safflower (Carthamus tinctorius L.) seeds have long been clinically used in Korea to promote bone formation and prevent osteoporosis. However, the beneficial effect has not been scientifically evaluated. Thus, in the present study we investigated whether phytoestrogen rich safflower seeds reduce bone loss in ovariectomized rats. Female Sprague-Dawley rats were subjected to bilateral ovariectomy or sham surgery. One week after the operation, ovariectomized rats were either fed a diet containing defatted safflower seeds or injected with 17b-estradiol (E2) for 4 weeks. As expected, ovariectomy resulted in a dramatic reduction in trabecular bone mass of the proximal tibia, increase in deposition of marrow fat, and in uterine atrophy. E2 treatment almost completely prevented bone loss as well as marrow adiposity, as examined by scanning electron microscopy and histomorphometry. Safflower seeds partially prevented ovariectomy-induced bone loss and slightly reduced marrow adiposity. Safflower seeds, in contrast to E2, exerted very weak uterotrophic action. In an attempt to elucidate the underlying mechanisms, effect of polyphenolic compounds extracted from safflower seeds on proliferation of osteoblast-like cells was also assessed in vitro. The mixed polyphenolic compounds stimulated growth of ROS 17/2.8 osteoblast-like cells in a dose-dependent manner (5-100 mg/ml), as potently as E2 and genistein. The present data provide the first direct in vivo evidence that safflower seeds have a protecting effect on bone loss caused by estrogen deficiency, without substantial effect on the uterus. The beneficial effect of safflower seeds may be mediated, at least in part, by the stimulating effect of polyphenolic compounds on proliferation of osteoblasts.

Abstract
Identified pi(+/-), K(+/-), p, and (-)p transverse momentum spectra at midrapidity in sqrt[s(NN)] = 130 GeV Au+Au collisions were measured by the PHENIX experiment at RHIC as a function of collision centrality. Average transverse momenta increase with the number of participating nucleons in a similar way for all particle species. Within errors, all midrapidity particle yields per participant are found to be increasing with the number of participating nucleons. There is an indication that K(+/-), p, and (-)p yields per participant increase faster than the pi(+/-) yields. In central collisions at high transverse momenta (p(T) > or =2 GeV/c), (-)p and p yields are comparable to the pi(+/-) yields.

Abstract
Two-pion correlations in square root[s(NN)] = 130 GeV Au+Au collisions at RHIC have been measured over a broad range of pair transverse momentum k(T) by the PHENIX experiment at RHIC. The k(T) dependent transverse radii are similar to results from heavy-ion collisions at square root[s(NN)] = 4.1, 4.9, and 17.3 GeV, whereas the longitudinal radius increases monotonically with beam energy. The ratio of the outwards to sidewards transverse radii (R(out)/R(side)) is consistent with unity and independent of k(T).

Abstract
Transverse momentum spectra of electrons from Au+Au collisions at square root[s(NN)] = 130 GeV have been measured at midrapidity by the PHENIX experiment at the Relativistic Heavy Ion Collider. The spectra show an excess above the background from photon conversions and light hadron decays. The electron signal is consistent with that expected from semileptonic decays of charm. The yield of the electron signal dN(e)/dy for p(T) > 0.8 GeV/c is 0.025+/-0.004(stat)+/-0.010(syst) in central collisions, and the corresponding charm cross section is 380+/-60(stat)+/-200(syst) microb per binary nucleon-nucleon collision.

Abstract
We report the observation of the decay mode B(+/-) --> p(-)pK(+/-)based on an analysis of 29.4 fb(-1) of data collected by the Belle detector at KEKB. This is the first example of a b-->s transition with baryons in the final state. The p(-)p mass spectrum in this decay is inconsistent with phase space and is peaked at low mass. The branching fraction for this decay is measured to be B(B+/--->p(-)pK+/-) = [4.3(+1.1)(-0.9)(stat)+/-0.5(syst)]x 10(-6). We also report upper limits for the decays B(0)-->p(-)pK(S) and B(+/-)-->p(-)p pi(+/-).

Abstract
Lamivudine-induced HBeAg seroconversion may not be durable in Korean patients with hepatitis B virus (HBV) infection. It is unknown whether virological response during lamivudine treatment affects the post-treatment outcome. We retrospectively analysed 124 consecutive HBeAg-positive chronic hepatitis B (CHB) patients treated with lamivudine. Lamivudine was given at a dose of 100 mg per day. HBV DNA levels in sera obtained before and during therapy were measured by the Digene Hybrid Capture II assay and Digene Ultrasensitive Hybrid Capture II assay, respectively. HBeAg seroconversion was achieved in 42 of the 124 patients (33.8%) treated with lamivudine. Mean duration of treatment in HBeAg seroconverters was 12.86 +/- 4.44 months. During the follow-up period, the cumulative relapse rates at 3 months and 6 months post-treatment in 42 patients with HBeAg seroconversion were 40.5% and 57.4%, respectively. Among 31 seroconverted patients whose sera were available at the second month of treatment, HBV DNA remained at > 4.7 x 103 genomes/mL in 15 patients and decreased to < 4.7 x 103 genomes/mL in the remaining 16 patients. HBV DNA levels at the second month of treatment was not related with relapse after discontinuation of treatment (66.7% vs. 43.8%, P= 0.2). At the time of HBeAg seroconversion, HBV DNA remained at > 4.7 x 103 genomes/mL in five patients and decreased to < 4.7 x 103 genomes/mL in the remaining 37 patients. Relapse rates were increased in patients who remained at > 4.7 x 103 genomes/mL compared with patients with HBV DNA levels < 4.7 x 103 genomes/mL (100% vs. 51.4%, P < 0.001). Thus, monitoring of serum HBV DNA at the time of HBeAg seroconversion may be helpful for predicting relapse in patients with lamivudine-induced HBeAg seroconversion.

Abstract
OBJECTIVE To investigate the diagnostic value of serum insulin-like growth factor-I (IGF-I) and insulin-like growth factor-binding protein-3 (IGFBP-3) measurements in adult patients with acromegaly and GH deficiency (GHD). METHODS Serum IGF-I and IGFBP-3 levels were measured in 39 active acromegalic patients, 34 adult patients with GHD and 150 healthy adults. Disease activity in patients with acromegaly was confirmed by nadir GH levels during an oral glucose tolerance test (OGTT). Among patients with acromegaly, 15 had not been treated previously and 24 had been treated but not cured. GHD in adults was diagnosed by an insulin tolerance test (ITT). Among patients with GHD, 15 were aged 20-40 years (9 men and 6 women) and 19 were aged over 40 years (9 men and 10 women). One hundred and fifty healthy subjects were recruited as a control group. To compare the individual serum IGF-I and IGFBP-3 levels of patients with the results of the gold standard, we calculated age- and sex-corrected standard deviation scores (SDS) for individual IGF-I and IGFBP-3 levels. The sensitivities of serum IGF-I and IGFBP-3 measurements for the disease diagnosis were analyzed using the mean +/- 2 SD of the values of healthy control subjects as a diagnostic cutoff, defining 95% specificity. RESULTS The mean IGF-I and IGFBP-3 SDS levels were significantly higher in active acromegalic patients, both untreated and treated but not cured, than in the control subjects (p < 0.05). The sensitivities of serum IGF-I and IGFBP-3 measurements for the diagnosis of acromegaly were 97.4 and 81.8%, respectively. In untreated patients with acromegaly, the sensitivities of serum IGF-I and IGFBP-3 measurements for the diagnosis of disease were 100 and 100%, while these were 95.8 and 72.7% in treated patients with acromegaly. In adult patients with GHD, the mean IGF-I and IGFBP-3 SDS were significantly lower than those of the control subjects (IGF-I, -2.2 +/- 0.8 vs. 0.0 +/- 1.0 SDS, p < 0.0001); IGFBP-3, -1.7 +/- 1.2 vs. 0.0 +/- 1.0 SDS, p < 0.0001), but there was a considerable overlap between GHD in adults and the controls. In all patients with GHD, the sensitivities of serum IGF-I and IGFBP-3 measurements were 64.7 and 52.9%, respectively. In the group of women aged 20-40 years, the sensitivity of IGF-I measurement for the diagnosis of GHD was 100%, although the number of patients was only 6. CONCLUSION Both serum IGF-I and IGFBP-3 measurements are comparable to an oral glucose tolerance test in patients with untreated acromegaly, but in acromegalic patients that have undergone surgery and/or radiotherapy, serum IGF-I is more valuable for determining disease activity than serum IGFBP-3. Serum IGF-I and IGFBP-3 measurements are not valuable for the diagnosis of GHD in adults, but in women aged 20-40 years serum IGF-I measurement appears to be useful in the diagnosis of GHD.

Abstract
The lifetimes of the B(0) and B- mesons are extracted from 29.1 fb(-1) of data collected with the Belle detector at the KEK B factory. A fit to the decay length differences of neutral and charged B meson pairs, measured in events where one of the B mesons is fully reconstructed in several hadronic modes, yields tau(B(0)) = 1.554+/-0.030(stat)+/-0.019(syst) ps, tau(B-) = 1.695+/-0.026(stat)+/-0.015(syst) ps, and tau(B-)/tau(B(0)) = 1.091+/-0.023(stat)+/-0.014(syst).

Abstract
We report a measurement of the D0-D macro(0) mixing parameter y(CP) using 23.4 fb(-1) of data collected near the Upsilon(4S) resonance with the Belle detector at KEKB. y(CP) is measured from the lifetime difference of D0 mesons decaying into the K(-)pi(+) state and the CP-even eigenstate K(-)K(+). We find y(CP) = (-0.5+/-1.0(+0.7)(-0.8))x10(-2), where the first error is statistical and the second is systematic, corresponding to a 95% confidence interval -0.030<y(CP)<0.020.

Abstract
Fibroblasts play an important role in the repair and remodelling processes following injury. Prostaglandin D2 (PGD2) is a potent mediator in inflammatory processes. In this study, the effect of the PGD2 on human foetal lung fibroblasts (HFL-1) chemotaxis induced by human plasma fibronectin (HFn) was investigated using the blindwell chamber technique. PGD2 inhibited HFL-1 chemotaxis to HFn (20 microg x mL(-1)) by 20.8 +/- 3.8% (p<0.05). Checkerboard analysis of HFn-directed migration confirmed that PGD2 inhibited both chemotaxis and chemokinesis. The effect of PGD2 was concentration-dependent and the inhibitory effect diminished with time. The PGD2 receptor (DP) agonist BW245C (500 nM) had a similar effect, inhibiting chemotaxis to 39.4 +/- 6.3%. The inhibitory effects of both PGD2 and BW245C on HFL-1 chemotaxis were blocked by the DP receptor antagonist AH6809 (2 microM). The inhibitory effect of PGD2 on fibroblast chemotaxis was also blocked by the cyclic adenosine monophosphate (cAMP)-dependent protein kinase (PKA) inhibitor, KT5720, suggesting a DP receptor-initiated, cAMP-dependent effect mediated by PKA. Prostaglandin D2 appears to inhibit fibroblast chemotaxis, perhaps by modulating the rate of fibroblast migration. Such an effect may contribute to regulation of the wound healing response following injury in asthma patients.

Abstract
1. Transcription factors such as NF-kappa B provide powerful targets for drugs to use in the treatment of cancer. In this report parthenolide (PT), a sesquiterpene lactone of herbal remedies such as feverfew (Tanacetum parthenium) with NF-kappa B inhibitory activity, markedly increased the degree of human leukaemia HL-60 cell differentiation when simultaneously combined with 5 nM 1 alpha,25-dihydroxyvitamin D(3) (1,25-(OH)(2)D(3)). PT by itself did not induce HL-60 cell differentiation. 2. Cytofluorometric analysis indicated that PT stimulated 1,25-(OH)(2)D(3)-induced differentiation of HL-60 cells predominantly into monocytes. 3. Pretreatment of HL-60 cells with PT before the 1,25-(OH)(2)D(3) addition also potentiated the 1,25-(OH)(2)D(3)-induced HL-60 cell differentiation in both a dose- and a time-dependent manner, in which the enhanced levels of cell differentiation closely correlated with the inhibitory levels of NF-kappa B binding activity by PT. 4. In contrast, santonin, a sesquiterpene lactone without an inhibitory activity of NF-kappa B binding to the kappa B sites, did not enhance the 1,25-(OH)(2)D(3)-induced HL-60 cell differentiation. 5. In transfection experiments, PT enhanced 1,25-(OH)(2)D(3)-induced VDRE-dependent promoter activity. Furthermore, PT restored 1,25-(OH)(2)D(3)-induced VDRE-dependent promoter activity inhibited by TNF-alpha, an activator of NF-kappa B signalling pathway. 6. These results indicate that PT strongly potentiates the 1,25-(OH)(2)D(3)-induced HL-60 cell differentiation into monocytes via the inhibition of NF-kappa B activity and provide evidence that inhibition of NF-kappa B activation can be a pre-requisite to the efficient entry of promyelocytic leukaemia cells into a differentiation pathway.

Abstract
Current evidence strongly indicates that reactive oxygen species (ROS) and reactive nitrogen species (RNS) are widely implicated in the inflammatory process. However, mechanistic information is not readily available on the extent to which ROS/RNS contributes to the proinflammatory states of the aging process. The involvement of the underlying inflammation during the aging process and the molecular delineation of anti-inflammatory action of calorie restriction (CR) is described. Age-related upregulations of NF-kappaB, IL-beta, IL-6, TNFalpha, cyclooxygenase-2, and inducible NO synthase are all attenuated by CR. The suppression of the NF-kappaB activation was accomplished by blocking the dissociation of inhibitory IkappaBalpha and IkappaBbeta by CR. These findings provide underlying molecular insights into the anti-inflammatory action of CR in relation to the aging process. Based on these and other available data, it is suggested that the "Inflammation Hypothesis of Aging" supports the molecular basis of the inflammatory process as a plausible cause of the aging process.

Abstract
The production of prompt J/psi, psi(2S), chi(c1), and chi(c2) is studied using a 32.4 fb(-1) data sample collected with the Belle detector at Upsilon(4S) and at 60 MeV below the resonance. The yield of prompt J/psi mesons in the Upsilon(4S) sample is compatible with that of continuum production; we set an upper limit B(Upsilon(4S)-->J/psiX) < 1.9 x 10(-4) at the 95% confidence level, and find sigma(e(+)e(-)-->J/psiX) = 1.47 plus/minus 0.10 plus/minus 0.13 pb. The cross sections for prompt psi(2S) and direct J/psi are measured. The J/psi momentum spectrum, production angle distribution, and polarization are studied.

We report the first observation of color-suppressed B( 0)-->D(0)pi(0), D(*0)pi(0), D0eta, and D0omega decays, and evidence for B( 0)-->D(*0)eta and D(*0)omega. The branching fractions are B(B( 0)-->D0pi(0)) = (3.1 +/- 0.4 +/- 0.5)x10(-4), B(B( 0) -->D(*0)pi(0)) = (2.7(+0.8+0.5)(-0.7-0.6))x10(-4), B(B( 0) --> D0eta) = (1.4(+0.5)(-0.4) +/- 0.3)x10(-4), B(B( 0) --> D0omega) = (1.8 +/- 0.5(+0.4)(-0.3))x10(-4), and we set 90% confidence level upper limits of B(B( 0) --> D(*0)eta)<4.6 x 10(-4) and B(B( 0)-->D(*0)omega)<7.9 x 10(-4). The analysis is based on a data sample of 21.3 fb(-1) collected at the Upsilon(4S) resonance by the Belle detector at the KEKB e(+)e(-) collider.

Abstract
Numerous reports exist upon clinical viewpoints of the four cervical cutaneous nerves. Unfortunately, a detailed description of the cervical cutaneous nerves has not yet been published. For this reason, administering effective anaesthesia to a particular nerve branch is difficult. The aim of this study was to clarify the anatomical knowledge about the emerging patterns of the cervical cutaneous nerves in the superficial neck using 35 Korean cadavers (22 male, 13 female). Four cervical cutaneous nerve branches penetrating the fascia of the posterior border of the sternocleidomastoid muscle (SCM) were classified into seven types based on the locations of their nerve emergence. Among these, the separated type (L-G-T-S) was the most frequent (50%). followed by the L-G x T-S type (20.3%), in which the great auricular nerve (G) and the transverse cervical nerve (T) emerged at the same level on the posterior SCM border.

Abstract
Using a sample of 31.3x10(6) BB pairs collected with the Belle detector at the Upsilon(4S) resonance, we make the first observation of the charged B meson decay to chi(c0) and a charged kaon. The measured branching fraction is B(B+-->chi(c0)K+) = (6.0(+2.1)(-1.8)+/-1.1)x10(-4), where the first error is statistical, and the second is systematic.

Abstract
We report a search for the flavor-changing neutral current decay B-->K(*)l+l- using a 29.1 fb(-1) data sample accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB e+e- storage ring. We observe the decay process B-->Kl+l-(l = e, mu), for the first time, with a branching fraction of B(B-->Kl+l-) = (0.75(+0.25)(-0.21)+/-0.09)x10(-6).

Abstract
Transverse momentum spectra for charged hadrons and for neutral pions in the range 1 GeV/c<p(T)<5 GeV/c have been measured by the PHENIX experiment at RHIC in Au+Au collisions at root square[s(NN)] = 130 GeV. At high p(T) the spectra from peripheral nuclear collisions are consistent with scaling the spectra from p+p collisions by the average number of binary nucleon-nucleon collisions. The spectra from central collisions are significantly suppressed when compared to the binary-scaled p+p expectation, and also when compared to similarly binary-scaled peripheral collisions, indicating a novel nuclear-medium effect in central nuclear collisions at RHIC energies.

Abstract
Thirty-one patients with stage IIIA non-small cell lung cancer (NSCLC) were treated with preoperative concurrent chemoradiotherapy (CCRT) followed by surgery. The treatment protocol could not be completed in eight patients. The acute hematologic toxicities of grade III or IV occurred in 48.4%, (15/31) after the first chemotherapy cycle, and in 39.1% (9/23) after the second cycle. The most common non-hematologic toxicity was radiation esophagitis. Surgery was attempted in 23 patients and successful in 22 patients (resection rate = 71.0%. Pathologic complete response and down-staging were achieved in 13.6% (3/22) and 68.2% (15/22). The median survival period, 2-year overall survival, local control and disease-free survival rates of all 31 patients and of 22 patients who underwent surgery were 19 months, 37.2%, 49.1%, 35.5%, and 19 months, 43.2%, 51.8%, 25.6%, respectively. On the basis of our observations, preoperative CCRT followed by surgery for stage IIIA NSCLC has resulted in outcomes comparable with those in previous reports.

Abstract
Fibroblast production of extracellular matrix is crucial not only for normal tissue development and maintenance of tissue structure but also for the repair and remodeling processes after injury. Thromboxane A(2) (TXA(2)) is a potent mediator in inflammatory processes. The aim of this study was to investigate the effect of TXA(2) on chemotaxis of human fetal lung (HFL-1) fibroblasts induced by human plasma fibronectin or platelet-derived growth factor BB (PDGF-BB). By using the blindwell chamber technique, the TXA(2) agonist U-46619 alone had no chemotactic activity. However, U-46619 (200 nmol/L) stimulated HFL-1 fibroblast chemotaxis to human plasma fibronectin (20 microg/mL; 161.8% +/- 13.4%; P <.005) and to PDGF-BB (10 ng/mL; 188.5% +/- 7.0%; P <.005). Checkerboard analysis of human plasma fibronectin-directed migration confirmed that the TXA(2) agonist increased both chemotaxis and chemokinesis. The stimulatory effect of the TXA(2) agonist was concentration dependent and increased with time. Another agent known for stimulating the protein kinase C pathway, phorbol 12-myristate 13-acetate (10(-8) mol/L), had a similar effect, stimulating chemotaxis to fibronectin (146.2% +/- 8.6%). The stimulatory effect of the TXA(2) agonist on HFL-1 fibroblast chemotaxis was inhibited by the synthetic thromboxane receptor antagonist SQ29,548 (10(-5) mol/L) and the protein kinase C inhibitor calphostin (10(-7) mol/L). In summary, TXA(2) appears to stimulate fibroblast chemotaxis to fibronectin and PDGF, perhaps by modulating the rate of fibroblast migration. Such an effect may contribute to regulation of wound healing and the development of fibrotic disorders.

Abstract
Temperature dependent optical conductivities and dc resistivity of c-axis oriented superconducting (T(c) = 39.6 K) MgB2 films (approximately 450 nm) have been measured. The normal state ab-plane optical conductivities can be described by the Drude model with a temperature independent Drude plasma frequency of omega(p,D) = 13 600+/-100 cm(-1) or 1.68+/-0.01 eV. The normal state resistivity is fitted by the Bloch-Grüneisen formula with an electron-phonon coupling constant lambda(tr) = 0.13+/-0.02. The optical conductivity spectra below T(c) of these films suggest that MgB2 is a multigap superconductor.

Abstract
Nitric oxide (NO) has been considered as an important mediator in inflammatory phases and in loss of cartilage. In inflammatory arthritis, NO levels are correlated with disease activity and articular cartilage is able to produce large amounts of NO with the appropriate inducing factor such as cytokines. The old animals are shown to have a greater sensitivity to NO than young animals. This study evaluated the basal production of NO in normal and OA-affected chondroyctes from young and old patients and compared the levels of NO formation in response to IL-1beta. The results showed that the basal levels were 7-fold higher in old chondrocytes than those of young cells. However, the IL-1beta induced NO production was seen to decrease with age. Aminoguianidine (AG), a competitive inhibitor of iNOS, inhibited NO formation completely in both chondrocytes from young and old individuals. However, at the same concentration of AG it caused partial inhibition of NO and iNOS formation in chondrocytes from OA-affected individuals. In addition, although the IL-1beta induced NO production was much lesser than that of young chondrocytes, the inhibition of collagen production by IL-1beta was prominent in old chondrocytes and OA-affected chondrocytes. These results suggest that age-related differences in the regulation of NO production and collagen production, which may affect the ageing cells and osteoarthritic changes in some way.
