Abstract
AIM To investigate whether 4 weeks of oral supplementation with coenzyme Q10 (CoQ10) would increase its concentration in skeletal muscle, and affect aerobic power (VO2max) and oxygen consumption during submaximal exercise in healthy, physically active men. METHODS Six volunteers with an average (+/-SD) age of 29.7+/-7.2 years and VO2max of 39.4+/-8.5 mL.kg-1.min-1, participated in a single-blind trial. The experiment consisted of 4 2-week phases, in the order of placebo run-in, CoQ10 supplementation (150 mg daily), CoQ10 (150 mg) plus vitamin E (1,000 IU daily), and placebo wash-out. A three-stage cycle economy test (4 minutes at each of 50, 100, and 150 watts), followed by a VO2max test (25 watts increment every minute till exhaustion), were performed prior to the supplementation and at the end of each phase. Blood samples were taken pre and post each VO2max test, and biopsy samples were obtained from the vastus lateralis muscle pre and post the 4 weeks of CoQ10 supplementation. RESULTS The plasma CoQ10 concentration was significantly elevated by the supplementation (P<0.05), however, it did not vary significantly pre and post each exercise test (P>0.05). The muscle CoQ10 concentration, VO2max ventilatory threshold, exercise economy and oxygen deficit showed no significant changes in response to the supplementation. CONCLUSION It was speculated that the non-significant effects of supplementation in healthy, non CoQ10-deficient men could be due to either that the mitochondrial membrane is normally saturated with CoQ10, or that the selected exercise testing protocol and variables were not sensitive enough to detect the effects.

Abstract
Selective inhibition of the BCR/ABL tyrosine kinase by imatinib has become a first-line therapy for chronic myelogenous leukemia (CML). However, BCR/ABL-positive progenitors often persist despite treatment, and relapse associated with resistance to imatinib has been described in many patients with advanced disease. Drug efflux by P-glycoprotein (P-gp), as well as point mutations in BCR/ABL oncoprotein, has been implicated in the mechanism of resistance to imatinib. In this study, we established a murine transplantation model of CML-like myeloproliferative disease using Mdr1a/1b-null mice and analyzed the effects of loss of P-gp on resistance to imatinib. We found that mice transplanted with Mdr1a/1b-null bone marrow (BM) that had been transduced with a BCR/ABL retroviral vector displayed similar responses to imatinib, compared with those transplanted with BCR/ABL-transduced wild-type BM. In the absence of P-gp, the incidence and latency of disease in secondary recipients was not changed in imatinib-treated mice, relative to wild-type controls. Furthermore, K562 cells engineered to overexpress P-gp remained sensitive to imatinib-induced growth inhibition and cell death. Together, our findings suggest that P-gp expression in hematopoietic stem cells does not significantly contribute to imatinib resistance in CML.

Abstract
New measurements are presented for charged hadron azimuthal correlations at midrapidity in Au+Au collisions at (square root)s(NN) = 62.4 and 200 GeV. They are compared to earlier measurements obtained at (square root)s(NN) = 130 GeV and in Pb + Pb collisions at (square root)s(NN) = 17.2 GeV. Sizeable anisotropies are observed with centrality and transverse momentum (pT) dependence characteristic of elliptic flow (upsilon2). For a broad range of centralities, the observed magnitudes and trends of the differential anisotropy, upsilon2(pT), change very little over the collision energy range (square root)s(NN) = 62-200 GeV, indicating saturation of the excitation function for upsilon2 at these energies. Such a saturation may be indicative of the dominance of a very soft equation of state for (square root)s(NN) approximately 60-200 GeV.

Abstract
The first measurement of direct photons in Au + Au collisions at (square root)S(NN) = 200 GeV is presented. The direct photon signal is extracted as a function of the Au + Au collision centrality and compared to next-to-leading order perturbative quantum chromodynamics calculations. The direct photon yield is shown to scale with the number of nucleon-nucleon collisions for all centralities.

Abstract
The development of dyskinesias and other motor complications greatly limits the use of levodopa therapy in Parkinson's disease (PD). Studies in rodent models of PD suggest that an important mechanism underlying the development of levodopa-related motor complications is alterations in striatal NMDA receptor function. We examined striatal NMDA receptors in the MPTP-lesioned primate model of PD. Quantitative immunoblotting was used to determine the subcellular abundance of NR1, NR2A and NR2B subunits in striata from unlesioned, MPTP-lesioned (parkinsonian) and MPTP-lesioned, levodopa-treated (dyskinetic) macaques. In parkinsonian macaques, NR1 and NR2B subunits in synaptosomal membranes were decreased to 66 +/- 11% and 51.2 +/- 5% of unlesioned levels respectively, while the abundance of NR2A was unaltered. Levodopa treatment eliciting dyskinesia normalized NR1 and NR2B and increased NR2A subunits to 150 +/- 12% of unlesioned levels. No alterations in receptor subunit tyrosine phosphorylation were detected. These results demonstrate that altered synaptic abundance of NMDA receptors with relative enhancement in the abundance of NR2A occurs in primate as well as rodent models of parkinsonism, and that in the macaque model, NR2A subunit abundance is further increased in dyskinesia. These data support the view that alterations in striatal NMDA receptor systems are responsible for adaptive and maladaptive responses to dopamine depletion and replacement in parkinsonism, and highlight the value of subtype selective NMDA antagonists as novel therapeutic approaches for PD.

Abstract
Ten alleles with length and nucleotide sequence variations were identified in the regulatory region of human tissue kallikrein gene. This present study aimed to study the polymorphisms of the regulatory region of human tissue kallikrein gene of the Chinese and investigate the relationship of the polymorphisms with essential hypertension. A case-control study was conducted in 200 hypertensive and 200 normotensive subjects of unrelated Chinese Han origin. All subjects were aged from 30 to 70 years and had no history of diabetes mellitus, kidney failure, or thyroid gland disease. The alleles were detected by polymerase chain reaction (PCR) and genotyping was performed with allele-specific oligonucleotide analysis (ASO). Data from the essential hypertensive and control subjects were statistically analysed by the Student's t-test and chi2-test. The age- and gender-matching of the groups were accurate. The case group and the control group were in Hardy-Weinberg equilibrium at this locus (cases, P=0.313; control subjects, P=0.457). There were nine alleles among the case and control groups, and the allele frequencies were found to be significantly different between cases and controls (chi2=25.701, P<0.001). The genotype frequencies were also significantly different (chi2=70.100, P<0.001) between these two groups. In conclusion, there are polymorphisms in the regulatory region of human tissue kallikrein gene in the Chinese Han people. Differences in both allele frequencies and genotype frequencies between these two groups have provided evidence towards the association of hypertension with the polymorphisms in this studied site.

Abstract
The production of deuterons and antideuterons in the transverse momentum range 1.1<p(T)<4.3 GeV/c at midrapidity in Au+Au collisions at square root of s(NN)=200 GeV has been studied by the PHENIX experiment at RHIC. A coalescence analysis, comparing the deuteron and antideuteron spectra with that of proton and antiproton, has been performed. The coalescence probability is equal for both deuterons and antideuterons and it increases as a function of p(T), which is consistent with an expanding collision zone. Comparing (anti)proton yields, p /p=0.73+/-0.01, with (anti)deuteron yields, d /d=0.47+/-0.03, we estimate that n /n=0.64+/-0.04. The nucleon phase space density is estimated from the coalescence measurement.

Abstract
The PHENIX experiment has measured midrapidity transverse momentum spectra (0.4<p(T)<4.0 GeV/c) of single electrons as a function of centrality in Au+Au collisions at sqrt[s(NN)]=200 GeV. Contributions from photon conversions and Dalitz decays of light neutral mesons are measured by introducing a thin (1.7% X0) converter into the PHENIX acceptance and are statistically removed. The subtracted nonphotonic electron spectra are primarily due to the semileptonic decays of hadrons containing heavy quarks, mainly charm at lower p(T). For all centralities, the charm production cross section is found to scale with the nuclear overlap function, T(AA). For minimum-bias collisions the charm cross section per binary collision is N(cc )/T(AA)=622+/-57(stat)+/-160(syst) microb.

Abstract
We report on charged hadron production in deuteron-gold reactions at sqrt[s(NN)]=200 GeV. Our measurements in the deuteron direction cover 1.4<eta<2.2, referred to as forward rapidity, and in the gold direction -2.0<eta<-1.4, referred to as backward rapidity, and a transverse momentum range p(T)=0.5-4.0 GeV/c. We compare the relative yields for different deuteron-gold collision centrality classes. We observe a suppression relative to binary collision scaling at forward rapidity, sensitive to low momentum fraction (x) partons in the gold nucleus, and an enhancement at backward rapidity, sensitive to high momentum fraction partons in the gold nucleus.

Abstract
AIMS To isolate endophytic Streptomyces strains from tomato and examine their antimicrobial activity. METHODS Endophytic Streptomyces strains were isolated using surface-sterilization methods and identified by morphological characteristics. Antimicrobial activities were measured by the agar plate sensitivity method. Antifungal activity in vivo was measured by seedling mortality in infested soils. RESULTS Twenty-one per cent of endophytic streptomycete isolates produced antibacterial metabolites and 41% produced antifungal metabolites in S medium. Sixty-five per cent of the most frequently isolated strains inhibited the growth of Rhizoctonia solani by the antibiosis assay but only 32% produced metabolites active against R. solani in S medium. Growth promotion and enhanced disease resistance of seedlings inoculated with Streptomyces sp. strain S30 were observed in tomato but not in cucumber seedlings. CONCLUSIONS Endophytic Streptomyces spp. strains were successfully isolated using stringent methods and strain S30 promoted growth and enhanced resistance to R. solani in tomato seedlings. SIGNIFICANCE AND IMPACT OF THE STUDY Endophytic streptomycetes showing antifungal activity in vitro and in vivo may indicate the potential for their use as biocontrol agents particularly of R. solani disease of tomato seedlings.

Abstract
Escherichia coli W3110 derivatives, strains SZ63 and SZ85, were previously engineered to produce optically pure D(-) and L(+)-lactate from hexose and pentose sugars. To expand the substrate range, a cluster of sucrose genes (cscR' cscA cscKB) was cloned and characterized from E. coli KO11. The resulting plasmid was functionally expressed in SZ63 but was unstable in SZ85. Over 500 mM D(-)-lactate was produced from sucrose and from molasses by SZ63(pLOI3501).

Abstract
We present a measurement of the double longitudinal spin asymmetry in inclusive pi(0) production in polarized proton-proton collisions at sqrt[s]=200 GeV. The data were taken at the Relativistic Heavy Ion Collider with average beam polarizations of 0.27. The measurements are the first in a program to study the longitudinal spin structure of the proton, using strongly interacting probes, at collider energies. The asymmetry is presented for transverse momenta 1-5 GeV/c at midrapidity, where next-to-leading-order perturbative quantum chromodynamic (NLO pQCD) calculations well describe the unpolarized cross section. The observed asymmetry is small and is compared to a NLO pQCD calculation with a range of polarized gluon distributions.
