Abstract
We present results of a search for D0-D(-)0 mixing and a measurement of R(D), the ratio of doubly Cabibbo-suppressed decays to Cabibbo-favored decays, using D0-->K+pi- decays from 57.1 fb(-1) of data collected near sqrt[s]=10.6 GeV with the BABAR detector at the PEP-II collider. At the 95% confidence level, allowing for CP violation, we find the mixing parameters x('2)<0.0022 and -0.056<y(')<0.039, and the mixing rate R(M)<0.16%. In the limit of no mixing, R(D)=[0.357+/-0.022(stat)+/-0.027(syst)]% and the CP-violating asymmetry A(D)=0.095+/-0.061(stat)+/-0.083(syst).

Abstract
With a sample of approximately 89 x 10(6) B(-)B pairs collected with the BABAR detector, we perform a search for B meson decays into pairs of charmless vector mesons (phi, rho, and K*). We measure the branching fractions, determine the degree of longitudinal polarization, and search for CP violation asymmetries in the processes B+-->phiK(*+), B0-->phiK(*0), B+-->rho(0)K(*+), and B+-->rho(0)rho(+). We also set an upper limit on the branching fraction for the decay B0-->rho(0)rho(0).

Abstract
We present measurements of the branching fractions of the decays B+-->eta'K+ and B0-->eta'K0. For B0-->eta(')K(0)(S) we also measure the time-dependent CP-violation parameters S eta'(K(0)(S)) and C eta'(K(0)(S)), and for B+-->eta'K+ the time-integrated charge asymmetry A(ch). The data sample corresponds to 88.9 x 10(6) BB pairs produced by e(+)e(-) annihilation at the Upsilon(4S). The results are B(B+-->eta'K+)=(76.9+/-3.5+/-4.4) x 10(-6), B(B0-->eta'K0)=(60.6+/-5.6+/-4.6) x 10(-6), S eta'(K(0)(S))=0.02+/-0.34+/-0.03, C eta'(K(0)(S))=0.10+/-0.22+/-0.04, and A(ch)=0.037+/-0.045+/-0.011.

Abstract
We present a measurement of time-dependent CP asymmetries and an updated determination of the CP-odd fraction in the decay B0-->D(*+)D(*-) using a data sample of 88x10(6)BB pairs collected by the BABAR detector at the PEP-II B Factory at SLAC. We determine the CP-odd fraction to be 0.063+/-0.055(stat)+/-0.009(syst). The time-dependent CP asymmetry parameters Im(lambda(+)) and /lambda(+)/ are determined to be 0.05+/-0.29(stat)+/-0.10(syst) and 0.75+/-0.19(stat)+/-0.02(syst), respectively. The standard model predicts these parameters to be -sin(2beta and 1, respectively, in the absence of penguin diagram contributions.

Limits on D0-macro D0 mixing and CP violation from the ratio of lifetimes for decay to K-pi+, K-K+, and pi- pi+. PHYSICAL REVIEW LETTERS 2003; 91:121801.

Abstract
We present a measurement of D0-macro D0 mixing parameters using the ratios of lifetimes extracted from samples of D0 mesons decaying to K-pi(+), K-K+, and pi(-)pi(+). Using 91 fb(-1) of data collected by the BABAR detector at the PEP-II asymmetric-energy B Factory, we obtain a value Y=[0.8+/-0.4(stat.)(+0.5)(-0.4)(syst.)]%, which, in the limit of CP conservation, corresponds to the mixing parameter y=Delta Gamma/2 Gamma. Using the difference in lifetimes of D0 and macro D0 mesons, we obtain the CP-violation parameter Delta Y=[-0.8+/-0.6(stat.)+/-0.2(syst.)]%.

Abstract
We report a study of the B meson decays, B+ --> J/psiphiK+, B0 --> J/psiphiK(0)(S), B0 --> J/psiphi, B0 --> J/psieta, and B0 --> J/psieta' using 56 x 10(6) B(-)B events collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II e(+)e(-) asymmetric-energy storage ring. We measure the branching fractions B(B+ --> J/psiphiK+)=(4.4+/-1.4(stat)+/-0.5(syst))x 10(-5) and B(B0 --> J/psiphiK(0)(S))=(5.1+/-1.9(stat)+/-0.5(syst))x 10(-5), and set upper limits at 90% confidence level for the branching fractions B(B0 --> J/psiphi)<9.2 x 10(-6), B(B0 --> J/psieta)<2.7 x 10(-5), and B(B0 --> J/psieta')<6.3 x 10(-5).

Abstract
We present the first study of the time-dependent CP-violating asymmetry in B0-->J/psi pi(0) decays using e(+)e(-) annihilation data collected with the BABAR detector at the Upsilon(4S) resonance during the years 1999-2002 at the PEP-II asymmetric-energy B Factory at SLAC. Using approximately 88 x 10(6) BB; pairs, our results for the coefficients of the cosine and sine terms of the CP asymmetry are C(J/psi pi(0))=0.38+/-0.41(stat)+/-0.09(syst) and S(J/psi pi(0))=0.05+/-0.49(stat)+/-0.16(syst).

Measurements of the branching fractions and bounds on the charge asymmetries of charmless three-body charged B decays. PHYSICAL REVIEW LETTERS 2003; 91:051801.

Abstract
We present measurements of branching fractions and charge asymmetries for charmless B-meson decays to three-body final states of charged pions and kaons. The analysis uses 81.8 fb(-1) of data collected at the Upsilon(4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. We measure the branching fractions B(B+-->pi(+)pi(-)pi(+))=(10.9+/-3.3+/-1.6)x10(-6), B(B+-->K+pi(-)pi(+))=(59.1+/-3.8+/-3.2)x10(-6), and B(B+-->K+K-K+)=(29.6+/-2.1+/-1.6)x10(-6) and provide 90% C.L. upper limits for other decays. We observe no charge asymmetries for these modes.

Abstract
We present results for the branching fractions and charge asymmetries in B+/--->h(+/-)pi(0) (where h(+/-)=pi(+/-),K+/-) and a search for the decay B0-->pi(0)pi(0) using a sample of approximately 88 x 10(6) BBmacr; pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure B(B+/--->pi(+/-)pi(0))=(5.5(+1.0)(-0.9)+/-0.6)x10(-6), where the first error is statistical and the second is systematic. The B+/--->pi(+/-)pi(0) signal has a significance of 7.7sigma including systematic uncertainties. We simultaneously measure the K+/-pi(0) branching fraction to be B(B+/--->K+/-pi(0))=(12.8(+1.2)(-1.1)+/-1.0)x10(-6). The charge asymmetries are Api(+/-)(pi(0))=-0.03(+0.18)(-0.17)+/-0.02 and AK+/-(pi(0))=-0.09+/-0.09+/-0.01. We place a 90% confidence-level upper limit on the branching fraction B(B0-->pi(0)pi(0)) of 3.6 x 10(-6).

Abstract
We have observed a narrow state near 2.32 GeV/c(2) in the inclusive D(+)(s)pi(0) invariant mass distribution from e(+)e(-) annihilation data at energies near 10.6 GeV. The observed width is consistent with the experimental resolution. The small intrinsic width and the quantum numbers of the final state indicate that the decay violates isospin conservation. The state has natural spin-parity and the low mass suggests a J(P)=0(+) assignment. The data sample corresponds to an integrated luminosity of 91 fb(-1) recorded by the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)e(-) storage ring.

Evidence for B+-->J/psip(-)Lambda; and search for B0-->J/psip(-)p. PHYSICAL REVIEW LETTERS 2003; 90:231801.

Abstract
We have performed a search for the decays B+-->J/psip(-)Lambda; and search for B0-->J/psip(-)p. in a data set of (88.9+/-1.0) x 10(6) Upsilon(4S) decays collected by the BABAR experiment at the PEP-II e(+)e(-) storage ring at the Stanford Linear Accelerator Center. Four charged B candidates have been observed with an expected background of 0.21+/-0.14 events. The corresponding branching fraction is (12(+9)(-6)) x 10(-6), where statistical and systematic uncertainties have been combined. The result can be interpreted as a 90% confidence level (C.L.) upper limit of 26 x 10(-6). We also find one B0 candidate, with an expected background of 0.64+/-0.17 events, implying a 90% C.L. upper limit of 1.9 x 10(-6).

Measurement of the branching fraction, and bounds on the CP-violating asymmetries, of neutral B decays to D*+/- D-/+. PHYSICAL REVIEW LETTERS 2003; 90:221801.

Abstract
We present measurements of the branching fraction and CP-violating asymmetries for neutral B decays to D(*+/-)D-/+. The measurement uses a data sample of approximately 88x10(6) Upsilon(4S)-->BBmacr; decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)-e(-) collider. By fully reconstructing the D(*+/-)D-/+ decay products, we measure the branching fraction to be (8.8+/-1.0+/-1.3)x10(-4) and the time-integrated CP-violating asymmetry between the rates to D(*-)D+ and D(*+)D- to be A=-0.03+/-0.11+/-0.05. We also measure the time-dependent CP-violating asymmetry parameters to be S(-+)=-0.24+/-0.69+/-0.12, C(-+)=-0.22+/-0.37+/-0.10 for B-->D(*-)D+ and S(+-)=-0.82+/-0.75+/-0.14, C(+-)=-0.47+/-0.40+/-0.12 for B-->D(*+)D-. In each case, the first error is statistical and the second error is systematic.

Measurement of the Cabibbo-Kobayashi-Maskawa matrix element V(ub) with B-->rhoenu decays. PHYSICAL REVIEW LETTERS 2003; 90:181801. [PMID: 12785997 DOI: 10.1103/physrevlett.90.181801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2002] [Indexed: 05/24/2023]
Abstract
We present a measurement of the branching fraction for the rare decays B-->rhoenu and extract a value for the magnitude of V(ub), one of the smallest elements of the Cabibbo-Kobayashi-Maskawa quark-mixing matrix. The results are given for five different calculations of form factors used to para-metrize the hadronic current in semileptonic decays. Using a sample of 55 x 10(6) BB meson pairs recorded with the BABAR detector at the PEP-II e(+)e(-) storage ring, we obtain B(B0-->rho(-)e(+)nu)=(3.29+/-0.42+/-0.47+/-0.55) x 10(-4) and |V(ub)|=(3.64+/-0.22+/-0.25(+0.39)(-0.56)) x 10(-3), where the uncertainties are statistical, systematic, and theoretical, respectively.

Abstract
We report evidence for the decays B0-->D(+)(s)pi(-) and B0-->D(-)(s)K+ and the results of a search for B0-->D(*+)(s)pi(-) and B0-->D(*-)(s)K+ in a sample of 84 x 10(6) upsilon(4S) decays into BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring. We measure the branching fractions B(B0-->D(+)(s)pi(-))=[3.2+/-0.9(stat)+/-1.0(syst)] x 10(-5) and B(B0-->D(-)(s)K+)=[3.2+/-1.0(stat)+/-1.0(syst)] x 10(-5). We also set 90% C.L. limits B(B0-->D(*+)(s)pi(-))<4.1 x 10(-5) and B(B0-->D(*-)(s)K+)<2.5 x 10(-5).

Abstract
We present a measurement of the branching fraction for the decay of the neutral B meson into the final state J/psipi(+)pi(-). The data set contains approximately 56 x 10(6) BB pairs produced at the Upsilon(4S) resonance and recorded with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring. The result of this analysis is B(B0-->J/psipi(+)pi(-))=(4.6+/-0.7+/-0.6) x 10(-5), where the first error is statistical and the second is systematic. In addition, we measure B(B0-->J/psirho(0))=(1.6+/-0.6+/-0.4) x 10(-5).

Abstract
We present measurements of branching fractions and CP-violating asymmetries for two-body neutral B meson decays to charged pions and kaons based on a sample of about 88x10(6) Upsilon(4S)-->BB decays. From a time-independent fit we measure the charge-averaged branching fractions B(B0-->pi+pi-)=(4.7+/-0.6+/-0.2)x10(-6), B(B0-->K+pi-)=(17.9+/-0.9+/-0.7)x10(-6), and the direct CP-violating charge asymmetry A(Kpi)=-0.102+/-0.050+/-0.016 [-0.188,-0.016], where the ranges in square brackets indicate the 90% confidence intervals. From a time-dependent fit we measure the B0-->pi+pi- CP-violating parameters S(pipi)=0.02+/-0.34+/-0.05 [-0.54,+0.58] and C(pipi)=-0.30+/-0.25+/-0.04 [-0.72,+0.12].

Measurement of the CP asymmetry amplitude sin2beta with B0 mesons. PHYSICAL REVIEW LETTERS 2002; 89:201802.

Abstract
We present results on time-dependent CP asymmetries in neutral B decays to several CP eigenstates. The measurements use a data sample of about 88 x 10(6) Upsilon(4S)-->B(-)B decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We study events in which one neutral B meson is fully reconstructed in a final state containing a charmonium meson and the other B meson is determined to be either a B(0) or B(-0) from its decay products. The amplitude of the CP asymmetry, which in the standard model is proportional to sin2beta, is derived from the decay-time distributions in such events. We measure sin2beta=0.741+/-0.067(stat)+/-0.034(syst) and |lambda|=0.948+/-0.051(stat)+/-0.030(syst). The magnitude of lambda is consistent with unity, in agreement with the standard model expectation of no direct CP violation in these modes.

Abstract
We report a measurement of the branching fraction of the decay B0-->D(*+)D(*-) and of the CP-odd component of its final state using the BABAR detector. With data corresponding to an integrated luminosity of 20.4 fb (-1) collected at the Upsilon(4S) resonance during 1999-2000, we have reconstructed 38 candidate signal events in the mode B0-->D(*+)D(*-) with an estimated background of 6.2+/-0.5 events. From these events, we determine the branching fraction to be B(B0-->D(*+)D(*-))=[8.3+/-1.6(stat)+/-1.2(syst)]x10(-4). The measured CP-odd fraction of the final state is 0.22+/-0.18(stat)+/-0.03(syst).

Abstract
The B(0) lifetime was measured with a sample of 23 million BB pairs collected by the BABAR detector at the PEP-II e(+)e(-) storage ring during 1999 and 2000. Events from the semileptonic decay B(0)-->D(*-)l(+)nu(l) have been selected with a partial reconstruction method in which only the charged lepton and the slow pi from the D*--->D(0)pi(-) decay are reconstructed. The result is tau(B(0)) = 1.529+/-0.012(stat)+/-0.029(syst) ps.

Abstract
We present results from a search for the flavor-changing neutral current decays B-->Kl(+)l(-) and B-->K(*)l(+)l(-), where l(+)l(-) is either an e(+)e(-) or mu(+)mu(-) pair. The data sample comprises 22.7 x 10(6) Upsilon(4S)-->B(-)B decays collected with the BABAR detector at the PEP-II B Factory. We obtain the 90% C.L. upper limits B(B-->Kl(+)l(-))<0.51 x 10(-6) and B(B-->K(*)l(+)l(-))<3.1 x 10(-6), close to standard model predictions for these branching fractions. We have also obtained limits on the lepton-family-violating decays B-->Ke+/-mu(-/+) and B-->K(*)e(+/-)mu(-/+).

Abstract
We report the results of a search for T and CP violation in B0-B-0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B Factory. The asymmetry between l+l+ and l-l- events allows us to compare the probabilities for B-0-->B0 and B0-->B-0 oscillations and thus probe T and CP invariance. Using a sample of 23 x 10(6) BB- pairs, we measure a same-sign dilepton asymmetry of A(T/CP) = [0.5+/-1.2(stat)+/-1.4(syst)]%. For the modulus of the ratio of complex mixing parameters p and q, we obtain q/p = 0.998+/-0.006(stat)+/-0.007(syst).

Abstract
Flavor oscillations of neutral B mesons have been studied in e+e- annihilation data collected with the BABAR detector at center-of-mass energies near the upsilon(4S) resonance. The data sample used for this purpose consists of events in which one B0 meson is reconstructed in a hadronic decay mode, while the flavor of the recoiling B0 is determined with a tagging algorithm that exploits the correlation between the flavor of the heavy quark and the charges of its decay products. From the time development of the observed mixed and unmixed final states, we determine the B0-B-0 oscillation frequency deltamd to be 0.516+/-0.016(stat)+/-0.010(syst) ps-1.

Abstract
The B0-B-0 oscillation frequency has been measured with a sample of 23 x 10(6) BB- pairs collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we select events in which both B mesons decay semileptonically and use the charge of the leptons to identify the flavor of each B meson. A simultaneous fit to the decay time difference distributions for opposite- and same-sign dilepton events gives deltamd = 0.493+/-0.012(stat)+/-0.009(syst) ps-1.

Abstract
The penicillamine (Pen) self-assembled monolayer (SAM) modified gold electrode (Pen/Au) is demonstrated to catalyze the electrochemical response of dopamine (DA) by cyclic voltammetry. A pair of well-defined redox waves was obtained and the calculated standard rate constant (k(s)) is 3.88 x 10(-3) cm/s at the self-assembled electrode. The electrode reaction is a quasi-reversible process. The oxidation peak of DA can be used to determine the concentration of DA. The peak current and the concentration of DA are a linear relationship in the range of 2.0 x 10(-5) M to 8.0 x 10(-4) M. The detection limit is 4.0 x 10(-6) M. By ac impedance spectroscopy the apparent electron transfer rate constant (k(app)) of Fe(CN)(3-)/Fe(CN)(4-) at the Pen/Au electrode was obtained as 2.08 x 10(-5) cm/s. The Pen SAM was characterized with X-ray photoelectron spectroscopy (XPS), grazing angle FT-IR spectroscopy and contact angle goniometer.

Abstract
OBJECTIVE To further study the renal damage of Sjögren's syndrome (SS) and its clinical and pathologic characteristics with biopsy and recent technology. METHODS 84 patients of SS with renal impairment from 1993 to 1999 were analyzed by routine, immunoassay, tubular function and biopsy examination. RESULTS 55 of the 84 cases presented with renal tubular acidosis (RTA), 5 with diabetes insipidus and 3 with hypokalemic paralysis. Glomerulopathy occurred in 22 cases (nephrotic syndrome 12, glomerulonephritis 10) and mild renal failure (RF) was found in 14. 69.1% of the patients had hypergamma-globulinemia. 64.3% and 44.1% of the patients showed positive anti SS-A and anti SS-B. In 37 renal biopsy specimens 21 showed chronic interstitial nephritis (CIN) with extensive lymphoplasmic cell infiltration and tubular atrophy. 10 of the 37 specimens revealed lupus nephritis (LN, type III and IV) and 5 mesangial proliferative glomerulonephritis (MsPGN). With immunofluorescence tests, no positive findings were seen in most of the specimens, but deposition of IgA, IgM or C(3) was seen in some patients. IgG deposits in the interstitial lymphoplasmic cells were found in 1 patient. 25 patients were treated with prednisone combined with cytoxan (CTX). In 14 patients with renal failure, serum creatinine level returned to normal after treatment. CONCLUSION Renal impairment may be the presenting or predominant feature in SS. The major clinical manifestations are RTA and GN. Treatment with prednisone may decrease the infiltration of lymphoplasmic cells in the interstitium, improve the renal function and correct RTA.

Abstract
OBJECTIVE To study the mechanism of cataractogenesis. METHODS Tissue culture was used to study the cataractous lenses of rats induced by sodium selenite or galactose. At the early stage, the content of nonprotein sulfhydryl (NP-SH), protein sulfhydryl (P-SH), non-soluble disulfide bond, malonaldehyde (MDA) and the activities of glutathione peroxidase (GSH-PX), glutathione reductase (GSSG-R) and glutathione-S-transferase (GSH-S) were measured in the cataractous lenses, and they were compared with that of the normal lenses. RESULTS The two kinds of material could all induce cataract in rats, sodium selenite being more potent. In the early period of culture (lenses were transparent), NP-SH and P-SH were decreased, while disulfide and MDA were increased, the activity of GSH-PX rose obviously, that of GSH-S also had a tendency of rise, however, the activity of GSSG-R had no obvious changes. CONCLUSIONS Rat lens opacity may occur after the lens is cultured in vitro with the addition of sodium selenite or galactose, and biochemical changes may develop in the lens at the early period of culture (lenses are transparent).

Abstract
OBJECTIVE To explore the effect of anti-P-selectin monoclonal antibody (mAb) on renal ischemia/reperfusion (I/R) injury in rats. METHODS Renal function, renal histopathological changes, plasma P-selectin levels and renal P-selectin protein and mRNA expression were studied in a renal I/R injury rat models. Biochemical measurement, ELISA, Immunohistochemistry and Nested RT-PCR were used. RESULTS Renal function insufficiency and renal histopathological damage were much less in the anti-P-selectin mAb-treated group than the saline-treated group. Plasma P-selectin levels were lower and renal P-selectin protein and mRNA expression were down-regulated in the former group. CONCLUSION Anti-P-selectin mAb might be an efficient approach for the treatment of renal I/R injury.

Abstract
OBJECTIVE To evaluate the effects of therapeutic lamellar and penetrating keratoplasty for fungal corneal ulcer. METHODS Donor corneas preserved in pure glycerine or water-free calcium chloride were used in corneal transplantation for fungal corneal ulcers that were poorly responsive to the anti-fungal medical treatment, 5% iodine was used in lamellar keratoplasty to kill the fungi in the recipient bed, and diluted or original solution of fluconazole was used in penetrating keratoplasty to wash the anterior chamber. RESULTS In the lamellar keratoplasty group, there were 23 cases; 18 cases were cured with one surgery and 3 cases were cured after second surgery, the success rate being 91.3%. There were 2 cases with recurrence of corneal inflammation, and the lesion was controlled by penetrating keratoplasty. The penetrating keratoplasty group included 31 cases, of them, 27 cases were cured with one surgery and 4 eyes were enucleated due to recurrent corneal inflammation or refractive glaucoma. In the total 54 cases, the inflammation was controlled in 50 cases after therapeutic corneal transplantation, success rate being 92.6%. CONCLUSIONS For those fungal corneal ulcers that are poorly responsive to anti-fungus eye drops, it is recommended to perform lamellar keratoplasty if the ulcer is located in the anterior 1/2 stroma, the key points of surgery are to remove the affected tissue completely and cauterize the recipient bed with 5% iodine. For deep ulcers or nearly perforative or perforated ulcers, diluted or original solution of diflucan is used to wash the anterior chamber during penetrating keratoplasty, that can help to improve the success rate.

Abstract
OBJECTIVE To determine points of radiofrequency thermocoagulation of the posterior rami of the lumbar nerves and to choose an effective temperature at which the conduction of painful impulse can be blocked. METHODS The posterior rami of the lumbar nerves were dissected in 15 corpses of adults. The ultrastructure of nerve fibres, changes of sensary conduction velocity (SCV) and the waveform of the unmedullated fibres which conduct painful impulse (c wave) were observed after the sciatic nerves of rabbits were coagulated at various temperatures (60 degrees C, 70 degrees C, 80 degrees C, 90 degrees C). RESULTS "Transverse Process Root Area" and "Transverse Process Point" can be regarded as primary marks of thermocoagulation of the posterior rami of the lumbar nerves. Stimulation of square-wave can make the location more accurate. While the temperature of thermocoagulation reached 80 degrees C, none of painful afferent nerve fibres survived. CONCLUSIONS With accurate location and good control of temperature, radiofrequency thermocoagulation will be an effective therapy for the patients suffering from pain resulted from pathological changes of the posterior rami of the lumbar nerves.

The pleiotropic effects of retinoic acid (RA) in mammalian cells are mediated by two classes of proteins: the retinoic acid receptors (RAR) and cellular retinoic acid-binding proteins (CRABP-I and CRABP-II). Here we show that expression of CRABP-II, but not CRABP-I, markedly enhanced RAR-mediated transcriptional activation of a reporter gene in COS-7 cells. The equilibrium dissociation constants of complexes of CRABP-I or CRABP-II with RA were found to differ by 2-fold. It is thus unlikely that the distinct effects of the two proteins on transactivation stem from differential ligand-binding affinities. The mechanisms by which RA transfers from the CRABPs to RAR were thus investigated directly. The rate constant for movement of RA from CRABP-II, but not from CRABP-I, to RAR strongly depended on the concentration of the acceptor. The data suggest that transfer of RA from CRABP-I to RAR involves dissociation of the ligand from the binding protein, followed by association with the receptor. In contrast, movement of RA from CRABP-II to the receptor is facilitated by a mechanism that involves direct interactions between CRABP-II and RAR. These findings reveal a striking functional difference between CRABP-I and CRABP-II, and point at a novel mechanism by which the transcriptional activity of RA can be regulated by CRABP-II.

Abstract
Peroxisome proliferator-activated receptors (PPAR alpha, beta, and gamma) are nuclear hormone receptors that play critical roles in regulating lipid metabolism. It is well established that PPARs are the targets for the hypolipidemic synthetic compounds known as peroxisome proliferators, and it has been proposed that various long-chain fatty acids and metabolites of arachidonic acid serve as the physiological ligands that activate these receptors in vivo. However, a persistent problem is that reported values of the equilibrium dissociation constants (Kds) of complexes of PPARs with these ligands are in the micromolar range, at least an order of magnitude higher than the physiological concentrations of the ligands. Thus, the identity of the endogenous ligands for PPAR remains unclear. Here we report on a fluorescence-based method for investigating the interactions of PPAR with ligands. It is shown that the synthetic fluorescent long-chain fatty acid trans-parinaric acid binds to PPARalpha with high affinity and can be used as a probe to monitor protein-ligand interactions by the receptor. Measurements of Kds characterizing the interactions of PPARalpha with various ligands revealed that PPARalpha interacts with unsaturated C:18 fatty acids, with arachidonic acid, and with the leukotriene LTB4 with affinities in the nanomolar range. These data demonstrate the utility of the optical method in examining the ligand-selectivity of PPARs, and resolve a long-standing uncertainty in understanding how the activities of these receptors are regulated in vivo.

Abstract
Gene transcription is often regulated by small ligands, enabling cells to respond to external and metabolic stimuli. Of particular interest are the mechanisms by which hydrophobic hormones modulate the transcriptional activities of proteins of the nuclear receptor superfamily. It was previously shown that, in the absence of ligand, the retinoid X receptor (RXRalpha) forms tetramers with a high affinity and a pronounced positive co-operativity such that tetramers become the receptor's predominant species tat concentrations as low as 60-70 nM. It was shown further that while RXR tetramers are remarkably stable in the absence of ligand, ligand-binding induces their rapid dissociation into smaller species, dimers and monomers. Here, the functional consequences of the self-association properties of RXR were studied by examining two point mutants of RXR that displayed aberrant oligomerization behaviors. One mutant, mRXRalpha-R321A, was found to form tetramers with a wild-type affinity, but these tetramers failed to dissociate upon ligand-binding. This mutant was found to be impaired in its ability to associate with the nuclear receptor co-activator p/CIP and to activate transcription in response to the RXR ligand 9-cis-retinoic acid. The other mutant, mRXRalpha-F318A, self-associated into dimers with a wild-type affinity, but was unable to form tetramers. This mutant displayed substantial transcriptional activity even in the absence of ligand. We previously proposed, based on in vitro studies that RXR acts as an auto-silencer by sequestering itself into tetramers, and that an important role for the ligand in activating this receptor is to release active species, dimers and monomers, from the transcriptionally inactive tetrameric pool. The observations reported here provide in-cell evidence in support of this model and indicate that ligand induced dissociation of tetramers is the first step in signalling by RXR.

Abstract
OBJECTIVE To investigate the incidence rate, pathologic changes, mechanisms and diagnostic methods in renal bone disease. METHODS The blood levels of carboxyterminal parpthyriod hormone (C-PTH), 1,25(OH)2D3, calcium and phosphate, aluminum in serum and bone tissue were measured. The bone biopsy and bone scan with 99m technetium methylene diphosphonate (99mTC-MDP) were performed in 51 uremic patients. RESULTS One hundred per cent of the patients had varying degree of pathologic changes in bone, in which 50.9% of the patients presented high-turnover bone disease, 7.8% of the patients presented low-turnover bone disease and 41.8% of the patients had mixed-type bone disease. The levels of serum C-PTH were predominently high in high-turnover bone disease while the levels of serum 1,25(OH)2D3 were significantly decreased in low-turnover bone disease. There was a high positive rate for the diagnosis of renal bone disease by bone scan with 99mTC-MDP. CONCLUSIONS The examination of bone pathology is the most valuable method for the diagnosis of renal bone disease. Bone scan with 99mTC-MDP has reference value when clinical conditions do not allow to make bone biopsy.

Abstract
OBJECTIVE To summarize the clinical and pathological findings of Alport syndrome (AS), detect the distribution of type IV collagen within basement membrane of patients with AS and evaluate the diagnostic value of indirect immunofluorescence (iIF) study of type IV collagen in AS. METHODS Fourteen patients belonging to 12 families were collected from January 1990 to June 1996. The clinical examinations include biochemical examination, audiometry and ocular examination. IIF technique was used to detect the location of chains of type IV collagen in 6 renal and 5 skin specimens from 8 Alport patients. RESULTS Among fourteen patients, 11 were male and 3 female (mean age 29.4 years). Microscopic hematuria was found in 13 patients, and recurrent gross hematuria in 7. All had proteinuria. Three patients presented nephrotic syndrome. Slowly progressive renal failure occurred in 10 of 11 males (11-39 years) and 1 female (40 years). Sensorineural deafness was observed in 9 patients particularly high frequency sound. Anterior lenticonus were presented in 2. Five families transmitted as X-linked dominant (XD) trait and 3 autosomal dominant, 3 autosomal recessive inheritance. In 7 renal biopsies, the findings by light microscopy mostly revealed focal and segmental sclerosis glomerulonephritis (4/7). The results of IF were negative in 4. Ultrastructural studies showed variable thickening, thinning of glomerular basement membrane (GBM) in 7 specimens with lamellation and basket wearing of GBM in 1. Using the iIF technique, the alpha 3, 4, 5 (IV) chains were observed to be absent within both GBM and EBM of 4 male XD-AS patients. Six patients were treated with hemodialysis, 2/6 with transplantation. CONCLUSION Alport syndrome (AS) is a heterogeneous hereditary disease characterized by progressive hematuric nephritis with or without sensorineural hearing loss and ocular defects. Ultrastructural alterations of GBM are helpful to the diagnosis of AS. IIF study suggests that type IV collagen in basement membrane of AS was abnormal and iIF study of type IV collagen chains distribution is useful for confirming the diagnosis of AS.

Abstract
The retinoid X receptor (RXR), a nuclear receptor that is activated by 9-cis-retinoic acid (9cRA), can regulate transcription as a homodimer or as a heterodimer with numerous other receptors. It was previously shown that, in the absence of ligand, RXR self-associates into homotetramers which are transcriptionally silent, and that ligand-binding induces dissociation of RXR tetramers into active species, dimers and monomers. Here, the implications of tetramer formation by RXR for the ability of the receptor to heterodimerize with the retinoic acid and the vitamin D receptors (RAR and VDR) were studied. In addition, the effects of cognate ligands for RXR and for RAR and VDR on formation of the respective heterodimers were examined. The data indicate that RXR subunits that are sequestered in tetramers were not available for interactions with RAR or VDR and, consequently, that in the absence of a RXR ligand, only a small fraction of this receptor became involved in heterodimers. RXR-selective ligands led to tetramer dissociation, but also inhibited the formation of heterodimers, directing a significant fraction of RXR into homodimers. Ligand binding by either heterodimerization partner significantly stabilized the respective heterodimer. Thus, maximal heterodimerization was observed in the presence of both 9cRA, acting to release active RXR species from tetramers, and the partner's cognate ligand, acting to overcome the inhibitory effect of 9cRA on heterodimer formation. These observations suggest that, by modulating protein-protein interactions within homo- and hetero-oligomers of RXR, cognate ligands control the relative distribution of potential RXR-containing complexes, thereby determining the transcriptional pathways that may be invoked under particular conditions in vivo.

Abstract
PURPOSE To measure the tensile strength of the anterior and posterior lens capsules in eye-bank eyes and study the tensile strength of capsules dehydrated with hypertonic glucose solution. SETTING Tongren Hospital, Beijing, China. METHODS The in situ anterior and posterior capsules of 35 eye-bank eyes (Group 1) donated by healthy men aged 20 to 40 years (mean 27.1 years) were measured with a biomembrane strength device. Sixteen eyes (Group 2), from donors aged 20 to 37 years (mean 27.0 years) and similar to those in Group 1, were measured in the same way after the anterior and posterior capsules were exposed to glucose 50% solution for 15 minutes. RESULTS In Group 1, anterior and posterior capsule strength was 6.269 +/- 1.118 and 3.755 +/- 0.835 g, respectively (P < .01), and the correlation between the tensile strength of the anterior and posterior capsules was statistically significant (r = .94; P < .001). In Group 2, the strength of the capsules increased to 9.024 +/- 0.586 and 4.424 +/- 0.761 g, respectively, a finding that was statistically significantly different from that in Group 1 (P < .01 and .05, respectively. CONCLUSION The tensile strength of the anterior capsule was stronger than that of the posterior capsule under the experimental conditions. Glucose 50% solution has the potential to increase the tensile strength of anterior and posterior capsules.

Abstract
OBJECTIVE To examine the relationship between P-selectin expression and human glomerulonephritis. METHODS P-selectin expression was investigated in renal biopsies of glomerulonephritis patients (n = 133) by immunohistochemical and in situ hybridization analyses. They were divided into three groups based on the degrees of cells proliferation or sclerosis. Group I: histological lesions in glomeruli are mild (n = 23); Group II: glomerular cells proliferation is prominent (n = 91); Group III: glomerular sclerosis is severe (n = 19). The Kruskal-Wallis test, Chisquare test and Spearman's correlation were used in our study. RESULTS In normal controls, renal P-selectin expression was negative (n = 10). In glomerulonephritis, the up-regulated P-selectin expression on tubular epithelium was significantly higher than that on glomeruli and interstitium (P < 0.01). P-selectin was expressed predominantly on platelets in glomeruli, and glomerular P-selectin expression was more significantly up-regulated in Group II than in Group I or Group III (P < 0.05; and P < 0.01, respectively). There were strong correlations between the degree of tubulointerstitial lesions and the expression of P-selectin on tubular epithelium or within interstitium (rs = 0.395 and rs = 0.337, P < 0.01). Furthermore, P-selectin messenger RNA (mRNA) signals were also detected in the cytoplasm of glomerulus, tubular epithelial cells, interstitium and vascular endothelium. CONCLUSIONS P-selectin might mediate intraglomerular platelets aggregation, activation and leukocyte accumulation in the early stages of human proliferative glomerulonephritis. The up-regulation of P-selectin in interstitium was associated with interstitial fibrosis and tubular atrophy and may contribute to the progression of glomerulonephritis.

Abstract
A pot trial was set up with nine soil types, each replicated five times, in randomized blocks, to investigate the effect of soil properties on the uptake of Al by soybean plants. The variance of the measurements was estimated using five replicates of each soil type. This then enabled the statistical significance of the difference between results for each soil type to be established. The analytical variance was determined by two analyses per pot. Systematic errors during the analytical procedure were estimated by the analysis of reagent blanks and CRMs. Analysis of variance (ANOVA) was used to estimate the proportions of total variance contributed by analysis, sampling and geochemistry. Robust statistics were required because of the high sensitivity of classical ANOVA to a small number of outlying values, due to either technical or geochemical causes. In the case study described here, traditional analytical quality control apparently gave a satisfactory result. However, the results from robust ANOVA showed that the sampling error was the limiting factor for this application. It is suggested that the environmental analyst must consider errors from procedures of both sampling and analysis of environmental samples.

Abstract
OBJECTIVE To reveal the incidence of MLL gene rearrangement and its clinical, features in acute myelomonocytic leukemia (M4) and acute monocytic leukemia (M5). METHODS 10 patients with M4 and 27 cases with M5 were studied with the Southern blot technique to detect MLL gene abnormalities. RESULTS 5 M5 patients were found to have MLL rearrangement, and these patients were characterized clinically by: (1) Younger at onset, (2) a higher white blood cell count (often > 100 x 10(9)/L), (3) frequent extramedullary involvement with hepatosplenomegaly and central nervous system leukemia (CNSL), and (4) a lower remission rate with a short survival time. CONCLUSION There is a high incidence of MLL rearrangement in M5, and this gene abnormality stands for a marker of poor prognosis.

Abstract
BACKGROUND We conducted a retrospective cohort study of lung cancer among silicotics in China's metallurgical industries. The study cohort consisted of 4372 male silicotics diagnosed and alive before 1 January 1980. The follow-up period was 1 January 1980 to 31 December 1989. RESULTS Standardized mortality ratios (SMR) of all deaths, all cancers, chronic bronchopneumonia, pneumonia and pulmonary heart disease, and pulmonary tuberculosis showed statistically significant excesses. The SMR for lung cancer for the total cohort was 237 (P < 0.01). When the total study cohort was divided into various categories by occupation (including iron ore mining, ore-sintering, refractory brick manufacturing, iron and steel smelting, and steel casting), significant excess lung cancer risk was observed among silicotics in all categories (SMR > 200, P < 0.01) except for casting (SMR = 157, P > 0.05). Excess lung cancer was not related to years since diagnosis of silicosis or years of exposure to silica. There was more than twofold excess lung cancer risk among both smoking (SMR = 257, P < 0.01) and non-smoking silicotics (SMR = 209, P < 0.01). Silicosis increased the risk of lung cancer.

Abstract
Both Hensen's node, the organizer center in chick embryo, and exogenous retinoic acid are known to induce limb duplication when grafted or applied to the host chick limb bud. Retinoic acid is known to be present in the node and has been proposed as the putative morphogen for chick limb development. Here, we report that Hensen's node from vitamin A-deficient quail embryo induces limb duplication in the host chick embryo similar to that induced by the node from vitamin A-sufficient control embryos. We also demonstrate that the expression of Sonic hedgehog (Shh), recently shown to be the mediator of polarizing activity in the chick limb bud, is not affected by the endogenous vitamin A status of the embryo. Furthermore, whole-mount in situ hybridization revealed asymmetry of Shh expression in the Hensen's node of both vitamin A-sufficient and -deficient quail embryos. Retinoids were not detectable in the eggs from which vitamin A-deficient embryos were obtained. Extracts from normal embryos induced a level of expression of reporter gene equivalent to the presence of 3.4 pg of active retinoids per embryo, while those from vitamin A-deficient embryos induced a baseline level of reporter gene expression similar to that of the controls. Our studies suggest that endogenous retinoic acid is not involved in Shh expression nor in regulating its asymmetry during normal early avian embryogenesis and support the current view that endogenous retinoic acid may not be a direct morphogen for limb bud duplication.

Abstract
Vitamin A is required to rescue the vitamin A-deficient quail embryo from early death, but the endogenous presence of bioactive retinoids has not been documented in these embryos. The analysis of 2000 pooled stage 5-8 normal quail embryos described here provides for the first time direct evidence for the presence of endogenous all-trans-retinoic acid (5 nM) and 3,4-didehydroretinoic acid (4 nM), signaling molecules known to be potent ligands for nuclear retinoic acid receptors. The demonstration of all-trans-retinal (80 nM), all-trans-retinol (100 nM), 3,4-didehydroretinol (200 nM), and retinyl esters (100 nM) suggests the capability of the early avian embryo to generate in situ the vitamin A-bioactive molecules required for development. Analysis of 2100 pooled stage 5-8 quail embryos from vitamin A-deficient eggs revealed no vitamin A-like molecules, supporting the evidence that links vitamin A deficiency in these embryos to abnormalities and early death.
