Abstract
A 7-year-old boy presented with adrenal insufficiency. He subsequently developed venous thrombosis in the limbs and was diagnosed with primary antiphospholipid syndrome (PAPS) based on clinical and laboratory parameters. Both adrenals were normal on imaging. He required thrombolysis and anticoagulation. The progressive course of PAPS was controlled with methylprednisolone. There are few reports of PAPS in pediatric patients, and associated adrenal involvement is rare. The unusual presentation, course and management of the patient and of four other reported children with adrenal insufficiency heralding manifestation of PAPS are discussed.

Abstract
CONTEXT Prediction of metastases of oral squamous cell carcinoma (OSCC) using incisional biopsy. AIMS To assess the efficacy of nuclear morphometry in predicting the nodal metastases of OSCC and to compare manual and computer-based image analyses. MATERIALS AND METHODS Sixteen cases of moderately differentiated squamous cell carcinoma (8 with metastasized lymph nodes and 8 node-negative cases) were examined using manual and computer-based image analyses. Nuclear area, perimeter, circular rate, larger to shorter axis ratio, and coefficient of variance of nuclear area (NACV) were calculated from 100 nuclei of the processed incisional biopsy specimen. STATISTICAL ANALYSIS The parameters were compared between the node positive and negative cases using Student's t test and with the level of lymph node involved using ANOVA test and Bonferroni's post hoc assessment. Manual and computer-based image analyses were compared by Spearman's correlation. RESULTS A significant variation between the node positive and negative groups was observed with respect to circular rate (P = 0.031) and NACV (P = 0.036). The nuclear area (P = 0.009), perimeter (P = 0.0001), circularity (P = 0.045), and larger to shorter diameter ratio (LS ratio) (P =0.02) were significantly different in the levels of the nodes involved. There was good a correlation between manual and computer-based analyses (Spearman's rho, 0.616-0.824) in nuclear size parameters and the circular rate had a negative correlation (-0.118, P = 0.664). Nuclear circularity was better assessed by computer-based analysis. CONCLUSION Preoperative morphometric assessment of the nuclear features may detect early cellular changes and thus, are useful in predicting nodal metastases in OSCC.

Abstract
ABSTRACTThe orientation dependence of phase separation has been examined in detail in InGaAsP layers grown by liquid phase epitaxy on (001), (110), (111)In and (123) InP substrates. It is shown that phase separation is two-dimensional in nature and does not occur along the growth direction for the cases examined. Further, phase separation takes place along the soft directions lying in the growth plane. These results very strongly suggest that phase separation evolves at the surface while the layer is growing.CuPt-type ordering characteristics of InGaAsP layers are presented. In addition, the Influence of growth temperature and growth rate on domain sizes have been investigated in GaInP2 layers. A model has been proposed to rationalize the formation of domains and involves steps present on the surface. Results suggest that ordering like phase separation occurs at the surface while the layers is being deposited. It is inferred that the two microstructural features evolve concomitantly at the surface during layer growth.

Abstract
ABSTRACTDuring the early stages of lattice mismatch epitaxy, island growth is observed in several systems. The evolution of this morphology is attributed to a large value of the substrate/layer interface energy. Origins of misfit and threading dislocations are also considered. Nucleation of misfit dislocations could occur either from steps present on surfaces of islands or from substrate/island edges. Arms of glide loops terminating at the surface in the first case form threading segments in the layer, whereas the coalescence of islands in which misfit dislocations are not aligned with respect to each other lead to threading dislocations in the second case. Existing approaches for lowering threading dislocation densities are also evaluated. A novel approach involving controlled, self-assembly of islands is presented to achieve the preceding objective.

Abstract
Kaposi's sarcoma (KS) is a multifocal neoplastic proliferation of endothelial cells predominantly involving skin and other organs. HIV-associated Kaposi's sarcoma has been rarely reported from India. A 38-year-old male presented with persistent swelling on the left lower limb for one year along with multiple erythematous to dusky papules and plaques of one and half months duration and swelling and black discoloration of right lower limb for one month. Cutaneous examination revealed numerous skin colored and erythematous papules and plaques distributed on the left lower limb on the anteromedial aspect and verrucous plaque on the left sole. Multiple erythematous, grouped papules were present over the soft palate. Skin biopsy showed numerous slit like spaces dissecting into the collagen of the upper and mid-dermis along with 'promontory sign' suggestive of Kaposi's sarcoma. Patient was found to be HIV-positive by ELISA test.

Abstract
Oligonucleotide-based arrays are increasingly becoming useful tools for the analysis of gene expression and single-nucleotide polymorphism. Here, we report a method that allows the direct immobilization of thiolated oligonucleotides onto an epoxy-activated glass surface via a stable thioether linkage under microwaves. The described chemistry efficiently immobilizes the probes via terminal thiol groups with uniform spot morphology. The thioether linkage could endure repeated PCR-like heat cycling with only 2.5% loss after 20 cycles, indicating that the chemistry can be used in integrated PCR/microarray devices. The highlighting feature of the proposed method is that the detection limit for the probe concentration can be reduced to 0.25 microM with 20-mer oligonucleotides. The efficiency of the projected method (approximately 33%) indicates its advantage over the existing standard methods, viz., NTMTA (approximately 9.8%), epoxide-amine (approximately 9.8%) and disulfide (approximately 1.7%). The constructed microarrays were validated through the detection of base mismatches and bacterial meningitis. These features make the projected strategy ideal for manufacturing oligonucleotide arrays and detection of mismatches and bacterial diseases.

Abstract
Pain during areteriovenous fistula (AVF) cannulation remains a common problem in hemodialysis (HD) patients. This study was undertaken to assess the effect of cryotherapy on pain due to arteriovenous fistula puncture in hemodialysis patients. A convenience sample of 60 patients (30 each in experimental and control groups) who were undergoing hemodialysis by using AVF, was assessed in a randomized control trial. Hemodialysis patients who met the inclusion criteria, were randomly assigned to experimental and control groups using a randomization table. Objective and subjective pain scoring was done on two consecutive days of HD treatment (with cryotherapy for the experimental and without cryotherapy for the control group). The tools used were a questionnaire examining demographic and clinical characteristics, an observation checklist for assessing objective pain behavior, and a numerical rating scale for subjective pain assessment. Descriptive statistics were used as deemed appropriate. Chi square, two-sample and paired t-tests, the Mann Whitney test, Wilcoxon's signed rank test, the Kruskal Wallis test, and Spearman's and Pearson's correlations were used for inferential statistics. We found that the objective and subjective pain scores were found to be significantly (P = 0.001) reduced within the experimental group with the application of cryotherapy. This study highlights the need for adopting alternative therapies such as cryotherapy for effective pain management in hospital settings.

Abstract
To understand the role of hypoxia-inducible factor (HIF)-2alpha in regulating sensitivity of renal cancer cells to tumor necrosis factor-related apoptosis inducing ligand (TRAIL)-induced apoptosis, we transfected wild-type and mutant von Hippel Lindau (VHL) proteins into TRAIL-sensitive, VHL-negative A498 cells. We find that wild-type VHL, but not the VHL mutants S65W and C162F that do not degrade HIF proteins, cause TRAIL resistance. Knock down of the HIF-2alpha protein by RNA interference (short hairpin RNA) blocked TRAIL-induced apoptosis, decreased the level of TRAIL receptor (DR5) protein and inhibited the transcription of DR5 messenger RNA. By using luciferase constructs containing the upstream region of the DR5 promoter, we demonstrate that HIF-2alpha stimulates the transcription of the DR5 gene by activating the upstream region between -448 and -1188. Because HIF-2alpha is thought to exert its effect on gene transcription by interacting with the Max protein partner of Myc in the Myc/Max dimer, small interfering RNAs to Myc were used to lower the levels of this protein. In multiple renal cancer cell lines decreasing the levels of Myc blocked the ability of HIF-2alpha to stimulate DR5 transcription. PS-341 (VELCADE, bortezomib), a proteasome inhibitor used to treat human cancer, increases the levels of both HIF-2alpha and c-Myc and elevates the level of DR5 in renal cancer, sensitizing renal cancer cells to TRAIL therapy. Similarly, increasing HIF-2alpha in prostate and lung cancer cell lines increased the levels of DR5. Thus, in renal cancer cell lines expressing HIF-2alpha, this protein plays a role in regulating the levels of the TRAIL receptor DR5.

Abstract
Panniculitis may result due to various etiologies. In post-transplant immunosuppressed patients infection is the foremost cause of panniculitis. We present 2 cases of fungal panniculitis in renal transplant recipients. The first patient presented with non-tender firm erythematous plaques on the left thigh. Biopsy showed panniculitis with cryptococci. Subsequent investigations revealed the presence of cryptococcal antigens in the blood, urine, and bronchoalveolar lavage fluid. There was no evidence of cryptococcal meningitis. The second patient complained of subcutaneous nodules on the trunk and right thigh. Biopsy of one of the nodules showed panniculitis with histoplasma. This patient had been treated earlier (inadequately) for disseminated histoplasmosis. Both the cases responded well to conventional amphotericin B therapy. Their renal functions remained stable.

Abstract
INTRODUCTION Steroid-induced osteoporosis is a major problem after organ transplantation. There is considerable evidence that bisphosphonates are effective in decreasing osteoporosis. AIM This prospective study was carried out to see the effects of bisphosphonates on bone mineral density (BMD) after successful renal transplantation. MATERIAL AND METHODS Fifty consecutive patients of successful renal transplantation were randomized into two groups. Group A (n = 27) received 35 mg/wk of Alendronate for 6 months after transplantation. Group B (n = 23) did not receive Alendronate and served as a control. Both groups underwent a pretransplant baseline dual-energy X-ray absorptiometry (DEXA) scan of their hips and lumber spines. Both groups received oral calcium and vitamin D supplement. Both groups were matched for the regimen and dose of immunosuppressive drugs. BMD was measured at 3 months and 6 months after transplantation. RESULTS Both groups showed a decline in BMD in early months posttransplantation. However, the 6-month DEXA scans showed a significant rise in BMD in group A as compared to group B. CONCLUSION Bisphosphonates appear to have a beneficial effect on steroid-induced bone loss.

Abstract
A facile and efficient method for direct immobilization of phosphorylated oligonucleotides on an epoxy-activated glass surface is described. The new immobilization strategy has been analyzed for its performance in DNA microarray under both microwave and thermal conditions. It reflects high immobilization efficiency ( approximately 23%), and signal-to-noise ratio ( approximately 98) and resulted in high hybridization efficiency ( approximately 36%) in comparison to those obtained with standard methods, viz., NTMTA ( approximately 9.76%) and epoxide-amine ( approximately 9.82%). The probes immobilized through the new strategy were found to be heat-stable, since the performance of microarray decreased by only approximately 7% after subjecting it to 20 PCR-like heat cycles, suggesting that the chemistry could be used in integrated PCR/microarray devices. The immobilization of probes following the proposed chemistry resulted in spots of superior quality in terms of spot morphology, spot homogeneity, and signal reproducibility. The constructed microarrays have been successfully used for the discrimination of nucleotide mismatches. In conclusion, these features make the new immobilization strategy ideal for facile, efficient, and cost-effective manufacturing of DNA microarrays.

Abstract
BACKGROUND Success of modern transplantation is in large part due to the successful development of effective immunosuppressive agents. The safety and efficacy of tacrolimus in transplantation is well established. However, tacrolimus (Pan Graf, Panacea Biotec Ltd, India) has only been available in India for the last 2 years. This study was conducted to assess the safety and efficacy of tacrolimus in live related kidney transplantation. We report an initial experience of tacrolimus as de novo therapy in a live related renal transplantation program. MATERIALS AND METHODS One hundred one consecutive recipients of a live renal allograft were commenced on triple immunosuppression consisting of tacrolimus, mycophenolate mofetil or azathioprine, and steroids. The dose of tacrolimus was adjusted to keep trough levels at 10-12 ng/mL in the first 3 months, 8-10 ng/mL in the next 3 months, and 5-8 ng/mL thereafter. All patients were followed up for a period ranging from 4 weeks to 24 months. The effect of this regimen on the incidence of graft rejection, graft survival, patient survival, and new-onset diabetes mellitus was evaluated. Any evidence of graft dysfunction was evaluated using a graft biopsy. RESULTS There were 89 male and 12 female patients with mean age of 32.08 years. The incidence of acute rejection was 3.96%; 21.05% developed new-onset diabetes mellitus. Six patients were diabetic prior to transplantation and 9 patients were hepatitis C virus (HCV)-positive; 77.7% of HCV-positive patients and 15.1% of HCV-negative patients developed posttransplantation diabetes mellitus. The patient survival rate at the current follow-up was 92.07%. No graft was lost due to rejection. CONCLUSION Tacrolimus is a safe and effective immunosuppressant in live related renal transplantation.

Abstract
Neisseria gonorrhoeae and Chlamydia trachomatis are the two most common bacterial sexually transmitted infections that manifest primarily as urethritis in males and endocervicitis in females, though the infection may be asymptomatic especially in women. Since complications may occur in untreated symptomatic and asymptomatic infected individuals, early diagnosis and treatment of infected individuals is required to prevent severe sequelae and spread of these diseases. Recently molecular amplification assays like Polymerase Chain Reaction (PCR) and Ligase Chain Reaction (LCR) have been found to be highly sensitive and specific methods for detection of N. gonorrhoeae and C. trachonmatis not only in urethral and cervical specimens but also in urine. The objective of this study was to screen male and female Sexually Transmitted Disease (STD) clinic attenders, with and without symptoms suggestive of urethritis and cervicitis for presence of N. gonorrhoeae and C. trachomatis using a multiplex PCR based assay, to compare its performance with culture for N. gonorrhoeae and Direct Fluorescent Antibody (DFA) staining for C. trachomatis and also to compare the efficacy of PCR test performed on urine and genital swab specimens collected from this high risk group. Genital specimens and urine was collected from STD clinic attenders. N. gonorrhoeae and C. trachomatis was detected in genital specimens by culture and DFA respectively. Multiplex PCR was used to detect N. gonorrhoeae and C. trachomatis infection in both genital and urine specimens. Among men with urethritis, N. gonorrhoeae was detected in 70% by culture and 77% by PCR, while C. trachomatis as detected in 7.5% by DFA and 17.5% by PCR. Among females with endocervicitis, N. gonorrhoeae was detected in 7.7% by culture and 30.7% by PCR, while C. trachomatis was detected in 7.7% by DFA and in 15.4% by PCR. None of the asymptomatic males were positive for N. gonorrhoeae and C. trachomatis by conventional methods, while 43.9% were positive for N. gonorrhoeae and 7.5% for C. trachomatis by PCR. Fifty per cent of asymptomatic women were positive for C. trachomatis by PCR alone. We encountered PCR positive but culture/DFA negative results and also PCR negative but culture/DFA positive results. In view of this a single PCR test cannot be used for diagnosis and treatment of N. gonorrhoeae and C. trachomatis infection unless confirmed by a second test.

Abstract
The microbial dynamics expressed in terms of culturable microbial populations i.e. bacteria, fungi, actinomycetes and Azotobacter were measured after 33 years of continuous application of mineral fertilizers and amendments to an acid alfisol. The bacterial, fungal and Azotobacter populations were maximum in plots treated with mineral fertilizers and FYM (100%NPK+FYM) while actinomycetes population was maximum in mineral fertilizes and lime treated plots (100%NPK+Lime). The bacterial population decreased and fungal population increased with increasing levels of NPK i.e. from 50% to 150%NPK. Bacillus species of bacteria and Gliocladium, Aspergillus and Rhizopus species of fungi were the main dominating culturable microorganisms in all the treatments. The FYM and lime amended plots sustained crop productivity and microbial populations at higher levels than rest of the mineral fertilizer treatments. The nitrogenous fertilizers alone had the most deleterious effect on crop productivity and the biological soil environment.

Abstract
PURPOSE To test the hypothesis that advanced stages of pelvic organ prolapse can result in a functional obstruction of the urethra, we studied the effects of manual prolapse reduction on urodynamic and urethral electromyographic parameters in women with stage III and IV pelvic organ prolapse. MATERIALS AND METHODS Women with advanced pelvic organ prolapse undergoing clinical multichannel urodynamics with concentric needle electromyography of the urethra were invited to participate in this institutional review board approved study. Women underwent filling cystometry and electromyography with prolapse everted and with prolapse reduced. Women were randomized to cystometry order (reduced vs everted). All subjects underwent a third study with prolapse reduction. Maximum urethral closure pressure and quantitative electromyography of the striated urethral sphincter were determined at maximum cystometric capacity. During the pressure flow study voiding parameters, including urethral electromyography quieting, were determined. The nonparametric paired sign test was used to evaluate differences in urodynamic parameters and quantitative electromyography with pelvic organ prolapse reduced and unreduced. Results were considered significant at the 5% level. RESULTS The 31 participants had mean age of 60 years (range 36 to 78) and 83% were white. There were no clinically significant differences in maximum cystometric capacity, voided volume, maximal flow and detrusor pressure at maximal flow or time to maximal flow between the reduced and everted prolapse states. Prolapse reduction resulted in a clinically and statistically significant decrease in maximum urethral closure pressure (-31%) but it had no impact on quantitative urethral electromyography. CONCLUSIONS These findings demonstrate that, although prolapse reduction significantly decreases maximum urethral closure pressure, it does not alter intrinsic neuromuscular activity of the striated urethral sphincter. Prolapse reduction does not alter any other filling or pressure flow parameter.

Abstract
Measurements of the production of forward pi0 mesons from p + p and d + Au collisions at square root sNN=200 GeV are reported. The p + p yield generally agrees with next-to-leading order perturbative QCD calculations. The d + Au yield per binary collision is suppressed as eta increases, decreasing to approximately 30% of the p + p yield at eta =4.00, well below shadowing expectations. Exploratory measurements of azimuthal correlations of the forward pi0 with charged hadrons at eta approximately 0 show a recoil peak in p + p that is suppressed in d + Au at low pion energy. These observations are qualitatively consistent with a saturation picture of the low-x gluon structure of heavy nuclei.

Abstract
A new self-aligned robust method for coupling to whispering gallery modes (WGMs) of submicron microspheres utilizes their periodic arrangement without relying on nanopositioned external coupling devices. The microspheres are embedded in a nanostructured gold surface supporting delocalized plasmonic crystal modes that mediate the coupling, and can be tuned by the geometry. Detailed measurements of the angle- and orientation-dependent reflectivity reveal localized plasmonic WGMs whose energies scale with sphere diameter and agree closely with Mie calculations. Coupling between these plasmonic WGMs leads to mode splitting and the formation of plasmonic minibands of a controllable bandwidth.

Abstract
The safety and efficacy of tacrolimus in transplantation is well established. However, tacrolimus has only recently been available in India. We report an initial experience using tacrolimus as de novo therapy in a living related renal transplant program. Fifty-two consecutive recipients of living renal allografts were treated with tacrolimus, mycophenolate mofetil, or azathioprine and steroids. The dose of tacrolimus was adjusted to keep trough levels at 10 to 12 ng/mL in the first 3 months, 8 to 10 ng/mL in the next 3 months, and 5 to 8 ng/mL thereafter. Any evidence of graft dysfunction was evaluated by graft biopsy. The effect of this regimen on the lipid profile as well as the incidence of posttransplant diabetes mellitus was evaluated in an Indian population. All patients were followed for periods ranging from 6 to 72 weeks (mean = 29 weeks). The incidence of acute rejection was 3.84%; 17.3% developed posttransplant diabetes mellitus. Graft and patient survivals at the current follow-up were 100% and 96.26%. In conclusion, tacrolimus is a safe and effective immunosuppressant in a living related renal transplant program.

Abstract
INTRODUCTION Subclinical rejection (SCR) in a normally functioning renal allograft may have an impact on long-term graft outcome. SCR detection is best done by protocol biopsies in clinically normal grafts. METHODS We evaluated 20 stable living related renal allografts with protocol biopsies on days 7 and 90 posttransplant. SCR when detected was treated with a 3-day pulse of methylprednisolone therapy. The outcomes of these grafts were compared with 63 other clinically stable renal allografts that did not undergo protocol biopsies. RESULTS SCR was observed in 60% of cases. The patients who received antirejection therapy for SCR based on protocol biopsies showed better graft survival and mean serum creatinine values at the end of the follow-up period.

Kaposis sarcoma (KS) occurs as four types; classic, endemic, immunosuppression-associated, and AIDS-associated. The presence of KS-associated herpesvirus (human herpesvirus 8) DNA in the tissue samples of 95% of all variants of KS has confirmed its role in the aetiopathogenesis of KS. It is now believed that these clinical variants most likely represent different manifestations of the same pathological process. Our case represents the first case of classic KS from our region.

Abstract
Charged hadrons in [EQUATION: SEE TEXT] associated with particles of [EQUATION: SEE TEXT] are reconstructed in pp and Au+Au collisions at sqrt[sNN]=200 GeV. The associated multiplicity and p magnitude sum are found to increase from pp to central Au+Au collisions. The associated p distributions, while similar in shape on the nearside, are significantly softened on the awayside in central Au+Au relative to pp and not much harder than that of inclusive hadrons. The results, consistent with jet quenching, suggest that the awayside fragments approach equilibration with the medium traversed.

Abstract
We report on the first measurement of elliptic flow v2(pT) of multistrange baryons Xi- +Xi+ and Omega- + Omega+ in heavy-ion collisions. In minimum-bias Au+Au collisions at square root of s(NN)=200 GeV, a significant amount of elliptic flow, comparable to other nonstrange baryons, is observed for multistrange baryons which are expected to be particularly sensitive to the dynamics of the partonic stage of heavy-ion collisions. The pT dependence of v2 of the multistrange baryons confirms the number of constituent quark scaling previously observed for lighter hadrons. These results support the idea that a substantial fraction of the observed collective motion is developed at the early partonic stage in ultrarelativistic nuclear collisions at the Relativistic Heavy Ion Collider.

Abstract
We present the first measurement of pseudorapidity distribution of photons in the region 2.3 < or = eta < or = 3.7 for different centralities in Au+Au collisions at square root of (S(NN)) = 62.4 GeV. We find that the photon yield scales with the number of participating nucleons at all collision centralities studied. The pseudorapidity distribution of photons, dominated by pi0 decays, has been compared to those of charged pions, photons, and inclusive charged particles from heavy-ion and nucleon-nucleon collisions at various energies. The photon production has been shown to be consistent with the energy and centrality independent limiting fragmentation scenario.

Abstract
The cytosolic glutathione S-transferases are a family of structurally homologous enzymes with multiple functions, including xenobiotic detoxification, clearance of oxidative stress products, and modulation of cell proliferation and apoptosis signaling pathways. This wide-ranging functional repertoire leads to several possible therapeutic uses for isoform-specific GST inhibitors. These inhibitors may be used, in principle, to modulate tumor cell drug resistance, as sensitizers to therapeutically directed oxidative stress, to enhance cell proliferation and to augment anti-malarial drugs. With increasing knowledge of GST structural and function, rational design strategies and mechanism-based inhibitors have been exploited successfully. However, design of isoform specificity remains a significant challenge in GST inhibitor development. Strategies for further inhibitor design and their possible limitations, along with potential therapeutic uses, are summarized.

Abstract
Midrapidity open charm spectra from direct reconstruction of D0(D0)-->K-/+pi+/- in d+Au collisions and indirect electron-positron measurements via charm semileptonic decays in p+p and d+Au collisions at squareroot[sNN]=200 GeV are reported. The D0(D0) spectrum covers a transverse momentum (pT) range of 0.1<pT<3 GeV/c, whereas the electron spectra cover a range of 1<pT<4 GeV/c. The electron spectra show approximate binary collision scaling between p+p and d+Au collisions. From these two independent analyses, the differential cross section per nucleon-nucleon binary interaction at midrapidity for open charm production from d+Au collisions at BNL RHIC is dsigma(NN)cc/dy=0.30+/-0.04(stat)+/-0.09(syst) mb. The results are compared to theoretical calculations. Implications for charmonium results in A+A collisions are discussed.

Abstract
We report a rare case of an association of external enamel pearl with internal enamel pearl on the root of a molar. To the best of our knowledge, association of external and internal enamel pearls has not been previously reported. We discussed the histogenesis of enamel pearls and proposed that internal enamel pearl formation may be a continuation of formation of external enamel pearl.

Abstract
Insulin-dependent diabetes mellitus is associated with renal failure, diabetic retinopathy, neuropathy and vasculopathy. We report the first successful simultaneous pancreas-kidney transplant in India in a young diabetic with renal failure. The dual transplant has cured his diabetes and renal failure and has had a beneficial effect on his neuropathy, retinopathy and quality of life. Obstacles to dual transplant in India include a lack of suitable recipients and a cadaver donor programme that is still in its infancy.

Abstract
Results on high transverse momentum charged particle emission with respect to the reaction plane are presented for Au + Au collisions at square root s(NN)=200 GeV. Two- and four-particle correlations results are presented as well as a comparison of azimuthal correlations in Au + Au collisions to those in p + p at the same energy. The elliptic anisotropy v(2) is found to reach its maximum at p(t) approximately 3 GeV/c, then decrease slowly and remain significant up to p(t) approximately 7-10 GeV/c. Stronger suppression is found in the back-to-back high-p(t) particle correlations for particles emitted out of plane compared to those emitted in plane. The centrality dependence of v(2) at intermediate p(t) is compared to simple models based on jet quenching.
