Abstract
Although machine learning (ML) has shown promise across disciplines, out-of-sample generalizability is concerning. This is currently addressed by sharing multi-site data, but such centralization is challenging/infeasible to scale due to various limitations. Federated ML (FL) provides an alternative paradigm for accurate and generalizable ML, by only sharing numerical model updates. Here we present the largest FL study to-date, involving data from 71 sites across 6 continents, to generate an automatic tumor boundary detector for the rare disease of glioblastoma, reporting the largest such dataset in the literature (n = 6, 314). We demonstrate a 33% delineation improvement for the surgically targetable tumor, and 23% for the complete tumor extent, over a publicly trained model. We anticipate our study to: 1) enable more healthcare studies informed by large diverse data, ensuring meaningful results for rare diseases and underrepresented populations, 2) facilitate further analyses for glioblastoma by releasing our consensus model, and 3) demonstrate the FL effectiveness at such scale and task-complexity as a paradigm shift for multi-site collaborations, alleviating the need for data-sharing.

Abstract
Purpose: 1) To Understand the male to female ratio prevailing in the organization 2) To Understand how effective are women development initiatives in organizations from a women’s perspective to determine if they will be appreciated and perceived as positive by the women. 3) To understand if the presence of women leaders in the organization leads to better engagement. 4) To understand, as suggested by research, are women leaders warmer and more male leaders more aggressive? Research Methodology: Sample - The sample size would be 50 men and women from all over India belonging to different age groups between 25-50 and are currently working in various corporations • Primary Research: In-Depth Interview, Survey • Secondary research: literature review • Analysis of the collected data Practical Implications: This will help identify why, even though there is awareness about the importance of having women leaders, the initiatives were taken for their development have not contributed significantly. This paper will help understand if these initiatives are enough in the given culture of the organization that has pre-defined norms and expectations from a woman’s standpoint of view. Originality: This research will mainly focus on the view of women about development initiatives in the organization.

Abstract
UNLABELLED The incident of End stage renal disease (ESRD) is rising rapidly worldwide. Renal transplant is the best modality of treatment, offering a better quality of life and mortality benefit, as compared with long-term dialysis. Very few patients have a live renal transplant donor, for rest, a decreased donor renal transplant is the only alternative. Deceased donor renal transplantation (DDRT) programs are only available at few government centers of India, constituting less than 5% of the total renal transplants. MATERIAL The patients who had undergone DDRT at our center from February 2015 to February 2021 were registered in the study. The following data were recorded for all patients; age, sex, duration of ESRD, cold ischemia time, type of induction, nadir and follow -up creatinine, hemoglobin, urinary protein and complications. All recipients were followed up and investigated in the outpatient department on a regular basis as per the standard guidelines till death or graft loss, whichever is earlier. Post transplant renal allograft function was measured using serum creatinine and other parameters. OBSERVATION During the study period 51 DDRTs were done. There were 40 male and 11 female patients. The mean age was 39.9 ± 9.8 years. The most common cause of ESRD in recipients was chronic glomerulonephritis (CGN) in 92.1 % (47). Amongst the patients, 41 (80.3%) survived, while 10 (19.6%) died post-transplant. Out of ten, 6 recipients died due to early sepsis (<3 months) and 4 died due to late sepsis (>3 months). Acute rejection was present in 17.6 % of patients. Mean post- transplant creatinine in recipients with functioning graft at discharge was 1.54 mg/dl. Graft failure was present in 7 patients out of which 2 were alive at the time of writing this paper and were on maintenance dialysis. Two patients died with a functioning graft. Delayed graft function (DGF) was seen in 13.7% (n=7) of recipients. The causes of DGF in our study included transplant renal artery thrombosis (n=2), Antibody-Mediated Rejection (n=3), mixed rejection (n=1) and Acute cellular rejection (n=1). Among those who had DGF, graft loss was seen in 57.2% (n=4). CONCLUSION In our study, the patient survival and graft survival have been better as compared to previous studies and also the number of recipients with delayed graft function have been low. Deceased donor renal transplantation is a practical treatment modality which can drastically improve longevity and quality of life.

Abstract
Alzheimer's disease (AD) is a global health concern owing to its complexity, which often poses a great challenge to the development of therapeutic approaches. No single theory has yet accounted for the various risk factors leading to the pathological and clinical manifestations of dementia-type AD. Therefore, treatment options targeting various molecules involved in the pathogenesis of the disease have been unsuccessful. However, the exploration of various immunotherapeutic avenues revitalizes hope after decades of disappointment. The hallmark of a good immunotherapeutic candidate is not only to remove amyloid plaques but also to slow cognitive decline. In line with this, both active and passive immunotherapy have shown success and limitations. Recent approval of aducanumab for the treatment of AD demonstrates how close passive immunotherapy is to being successful. However, several major bottlenecks still need to be resolved. This review outlines recent successes and challenges in the pursuit of an AD vaccine.

Abstract
Serum prostatic specific antigen (PSA) and serum testosterone levels share an undefined relationship with each other, with many conflicting studies showing both positive and negative correlation between them. Our aim was to assess association between serum PSA and serum testosterone in healthy men with normal testosterone levels and men with partial androgen deficiency (PADAM). A cross sectional study was conducted at a teaching hospital setting where serum testosterone and aging male symptom scale (AMS) scores along with PSA were studied in 255 men (> 50 years) with and without PADAM. Mean total testosterone and serum PSA was 9.35 ± 1.33 nmol/L, 1.96 ± 0.76 ng/mL in males with PADAM and 15.30 ± 1.95 nmol/L, 1.85 ± 0.73 ng/mL respectively in males without PADAM. No significant relationship was observed between serum PSA and serum testosterone levels among healthy males irrespective of PADAM in the study population. We suggest, there is no need to adjust PSA values for biopsy decisions according to testosterone levels.

Abstract
Paraneoplastic cerebellar degeneration (PCD) is a rare disorder that is associated with lung or gynecological malignancies and Hodgkin lymphoma. Neurologic symptoms are commonly the initial presenting sign leading to the diagnosis of an underlying malignancy. We are presenting an Asian male with progressive lower extremity weakness with EBV-positive nasopharyngeal carcinoma (NPC) and anti-Yo antibodies. Peculiarly, transient diffuse leptomeningeal enhancement is seen on MR imaging. This is the first report of PCD associated with NPC and thus illustrates that PCD embodies a boarder set of disease than previously described.

Abstract
Posttransplant lymphoproliferative disorder (PTLD) is reported in 1%–3% among pediatric renal allograft recipients. We report the experience of PTLD among pediatric renal allograft recipients at a pediatric nephrology center in North India. Four cases of PTLD were identified from among records of 95 pediatric renal allograft recipients over a period of 21 years. Constitutional and localizing symptoms were present in three patients each. The diagnosis was suggested on positron emission tomography in three patients and confirmed by histopathology in all. Sites affected included tonsils, cervical lymph nodes, duodenum, and para-aortic lymph nodes in one patient each. The lymphocytic infiltrate was polymorphic in three patients and monomorphic in one. Immunostaining suggested B-cell origin in all patients. There was evidence of Epstein–Barr virus infection in only one patient. The patients were successfully managed with reduction of immunosuppression (in all), rituximab (in 3), and excision of affected tissue (in 1). Over a follow-up period of 30–88 months, there were no episodes of disease recurrence or allograft rejection, and renal function was preserved.

Abstract
IgG4-related disease (IgG4-RD) is a multisystemic mass forming immune-mediated disease entity, commonly creating confusion and diagnostic challenges. We present a case of a 25-year-old female who presented with bilateral orbital masses, lymphadenopathy, paraspinal and renal masses, which clinicoradiologically simulated lymphoma. The lymph node biopsy revealed interfollicular sheets of plasma cells creating confusion with Castleman's disease and marginal zone lymphoma. The orbital biopsy revealed ductular destruction, periductular plasma cells, and fibrosis, mimicking Sjogren's syndrome and Castleman's disease. However, the correlation of the clinical features with histopathological findings, IgG4 immunopositivity, and serum studies helped in clinching the diagnosis. This case presents an uncommon combination of clinical features infrequently reported in literature. Furthermore, and more importantly, it highlights the need to keep a differential of IgG4-RD in mind, to aid early and correct treatment of the disease.

Abstract
Abstract
Background A large proportion of subjects with type 2 diabetes mellitus (T2DM) in India are non-obese. Asian-Indian subjects with diabetes have been shown to have low vitamin D levels. Whether low vitamin D levels and T2DM in Asian-Indians is attributable to the associated obesity as in caucasians is unclear. Hence we studied the association of vitamin D levels and T2DM in Asian-Indians with or without obesity.
Methods Total of 213 subjects were recruited in four groups, group 1-Non-obese diabetic, group 2-Non-obese non-diabetic, group 3-Obese diabetic and group 4-Obese non-diabetic. Subjects recruited under various groups were matched for age and sex. Anthropometry, skin-fold thickness, fasting and postprandial plasma glucose, HbA1c, fasting insulin, lipids and vitamin D levels were measured in all study subjects and were compared between the groups.
Results Mean age of study population was 41.23±7.43 years. Mean BMI in groups 1,2,3 and 4 was 21.34±1.41, 20.53±2.27, 27.72±2.94 and 27.62±3.37 kg/m2 respectively. Overall 64.3% study subjects had vitamin D deficiency and 27.7% had insufficient vitamin D levels. Significantly lower vitamin D levels were found in diabetic groups 1 and 3 compared to non-diabetic groups 2 and 4. No significant difference was observed in vitamin D levels between groups 1 and 3. Similarly, no significant difference was observed in vitamin D levels between groups 2 and 4. Vitamin D levels did not show any significant correlation with BMI, waist or body fat.
Conclusion Vitamin D levels do not appear to be related to obesity in diabetic as well non-diabetic Asian-Indian individuals.

Abstract
BACKGROUND Effect of anaesthesia and surgery on cell-free DNA (cfDNA) is not known. Given that surgical stress augments inflammation and injury, we hypothesized that levels of cfDNA will fluctuate during perioperative period. Therefore, in this study serial perioperative cfDNA concentration was measured in donors and recipients undergoing living donor liver transplantation (LDLT). METHODS Baseline, post-induction, intraoperative and post-operative plasma cfDNA levels were evaluated in 21 donors and recipients each, by Sytox green method. In addition, qPCR was performed in a subset of samples. RESULTS Baseline cfDNA levels were higher in recipients (37.62 ng/ml) than in donors (25.49 ng/ml). A decrease in cfDNA was observed following anaesthesia induction in both recipients (11.90 ng/ml) and donors (10.75 ng/ml). When the kinetics of the cfDNA was monitored further, an increase was noted intraoperatively in donors (46.18 ng/ml) and recipients (anhepatic phase: 56.25 ng/ml, reperfusion phase: 54.36 ng/ml). cfDNA levels remained high post-operatively. One recipient who developed post-operative sepsis had the highest cfDNA level (94.72 ng/ml). CONCLUSION Plasma cfDNA levels are high in recipients indicative of liver injury. Lower cfDNA levels following induction may be attributed to the subduing effect of anaesthetic agents on cell death. High cfDNA levels seen in intra- and post-operative phases reflect cellular trauma and inflammation. This similar pattern of fluctuation of cfDNA level in donors and recipients is suggestive of its possible utility as a surgical stress marker. In addition, comparable cfDNA levels in anhepatic and reperfusion phase reflect less ischemia reperfusion injury during LDLT.

Abstract
We describe two types of waveguides (type I and depressed cladding) inscribed in lithium niobate using a variable repetition rate (200 kHz-25 MHz), 270 fs duration fiber laser. The type I modification-based waveguides have propagation losses in the range from 1.2 to 10 dB/cm at 1550 nm, depending on experimental parameters. These waveguides are not permanent; they deteriorate over time. Such deterioration of waveguides can be slowed down from 30 days to 100 days by pre-annealing the samples and by writing at a 720 kHz laser repetition rate. The propagation losses measured at 1550 nm show significant improvement for pre-annealed samples. The depressed cladding-inscribed waveguides are permanent, but the propagation loss depends on the number of damage tracks. A track separation of ∼1 μm between adjacent damage tracks yields the lowest propagation loss of 0.5 dB/cm at 1550 nm for a 40 μm diameter waveguide. We observe multimode guidance for sizes in the range of 20-80 μm in these waveguide structures at 1550 nm. Their crystalline nature is found to remain intact, as inferred from second-harmonic generation within the waveguide region.

Abstract
Shrub-induced soil property spatial heterogeneity is common in arid and semi-arid ecosystems and aids desertified land restoration. However, the effectiveness of this technique may rely on the plant species used and the habitat conditions present. To assess the degree to which planting two native species, Haloxylon salicornicum and Calligonum polygonoides, facilitates degraded land restoration, soil and herbaceous plant community properties were measured 7 years after planting. Soil samples were extracted at two depths (0-5 and 5-20 cm) from three sub-habitats, i.e., under the shrub canopy, from alleys between shrubs and from the open area. Shrub planting increased the quantity of silt + clay content (30-39 %); enhanced water holding capacities (24-30 %); increased the levels of organic carbon (48-69 %), available nitrogen (31-47 %), available phosphorus (32-41 %), and electrical conductivity (21-33 %); and decreased the pH (7-12 %) and bulk density levels (5-6 %) in the surface layer of soils beneath the canopy. Soil property changes were more significant at the surface (0-5 cm) than in the deeper layer (5-20 cm), and were more pronounced under H. salicornicum than under C. polygonoides. Furthermore, the density and biomass levels of herbaceous plants were 1.1 to 1.2 and 1.4 to 1.6 times greater, respectively, in the shrub alleys than in open area. H. salicornicum induced more robust soil amelioration and herbaceous plant facilitative properties than did C. polygonoides. Artificially planting these shrubs may thus be employed to restore degraded areas of arid regions.

Abstract
Structural, magnetic, specific heat, and dielectric studies were carried out on Y substituted (30 at. %) GdMnO(3) compound as a function of temperature. Anomalies occur at ~41 and 18 K, in the specific heat measurements and are ascribed to paramagnetic, to sinusoidal incommensurate antiferromagnetic transition (ICAFM) and ICAFM to commensurate antiferromagnetic transitions, respectively. Changes in the lattice parameters across these temperatures indicate magneto-elastic coupling present in the compound. However, in the dielectric measurements, an anomaly at 18 K alone is observed and is ascribed to a ferroelectric transition, giving rise to spontaneous ferroelectric ordering at low temperatures. This observation is supported by an anomaly in lattice parameters, across the transition temperature. From the frequency dependent dielectric studies, a strong coupling between Gd(3+) and Mn(3+) magnetic sublattices is inferred and Y substitution results in substantial changes in the relaxation process compared to that of GdMnO(3).

Abstract
Spin valves have revolutionized the field of magnetic recording and memory devices. Spin valves are generally realized in thin film heterostructures, where two ferromagnetic (FM) layers are separated by a nonmagnetic conducting layer. Here, we demonstrate spin-valve-like magnetoresistance at room temperature in a bulk ferrimagnetic material that exhibits a magnetic shape memory effect. The origin of this unexpected behavior in Mn(2)NiGa has been investigated by neutron diffraction, magnetization, and ab initio theoretical calculations. The refinement of the neutron diffraction pattern shows the presence of antisite disorder where about 13% of the Ga sites are occupied by Mn atoms. On the basis of the magnetic structure obtained from neutron diffraction and theoretical calculations, we establish that these antisite defects cause the formation of FM nanoclusters with parallel alignment of Mn spin moments in a Mn(2)NiGa bulk lattice that has antiparallel Mn spin moments. The direction of the Mn moments in the soft FM cluster reverses with the external magnetic field. This causes a rotation or tilt in the antiparallel Mn moments at the cluster-lattice interface resulting in the observed asymmetry in magnetoresistance.

Abstract
BACKGROUND Tobacco use is a serious public health challenge in several regions of the world, including India. Increasingly, steps are being taken at policy level to curb the problem. AIM This study was done to find out the determinants of tobacco use so that effective intervention programs can be designed and implemented for the prevention and cessation of this growing pandemic. METHODS A community-based cross-sectional study was done adapting Global Youth Tobacco Survey questionnaire prepared by the Centre for Disease Control, Atlanta, among youth (15-24 years). Patterns of smoking and their determinants were calculated using univariate and multivariate analyses. RESULTS Prevalence of current smoking among youth was 20.4% (95% confidence interval: 16.9-23.9%). Male sex, smoking peers, cigarette advertisements, and feeling comfortable in social gatherings were significant determinants for smoking after adjusting for all explanatory variables. CONCLUSION Strict enforcement of regulations pertaining to cigarette advertisements in any form, enabling environment and community interventions focusing on parents and peers are required for effective control of tobacco problem among youth in India.

Abstract
To address the claim that the Leningrad-Zagreb (L-Z) mumps vaccine strain is causally associated with aseptic meningitis, a prospective, post-marketing safety study was conducted with a measles-mumps-rubella vaccine (MMR) (TRESIVAC(R); Serum Institute of India Ltd., Pune, India), which uses the L-Z strain as its mumps component in Egypt. In all, 453 119 children (65 423 children aged 16-24 months and 329 211 children aged 5-7 years) received MMR. The control groups which, as a result of local health regulations, were slightly younger than vaccinees, comprised 12 253 and 46 232 children, respectively. Using questionnaires, the parents recorded solicited local, systemic and neurological adverse events for up to 42 days post-vaccination. All data were analysed externally on an intention-to-treat basis by individuals not participating in the study. Local and/or systemic reactions were reported in a small percentage of participants, with pain, fever and parotitis being the most common signs among vaccinees in both age groups. No case of aseptic meningitis, encephalitis, anaphylaxis or convulsions was observed in any participant. Thus, in this series of more than 450 000 Egyptian children, the L-Z mumps vaccine strain in this vaccine did not cause aseptic meningitis. The vaccine is considerably cheaper than Western competitors and a valid alternative to other MMR vaccines.

Abstract
In ultraperipheral relativistic heavy-ion collisions, a photon from the electromagnetic field of one nucleus can fluctuate to a quark-antiquark pair and scatter from the other nucleus, emerging as a rho{0}. The rho{0} production occurs in two well-separated (median impact parameters of 20 and 40 F for the cases considered here) nuclei, so the system forms a two-source interferometer. At low transverse momenta, the two amplitudes interfere destructively, suppressing rho{0} production. Since the rho{0} decays before the production amplitudes from the two sources can overlap, the two-pion system can only be described with an entangled nonlocal wave function, and is thus an example of the Einstein-Podolsky-Rosen paradox. We observe this suppression in 200 GeV per nucleon-pair gold-gold collisions. The interference is 87%+/-5%(stat.)+/-8%(syst.) of the expected level. This translates into a limit on decoherence due to wave function collapse or other factors of 23% at the 90% confidence level.

Abstract
Three-particle azimuthal correlation measurements with a high transverse momentum trigger particle are reported for pp, d+Au, and Au+Au collisions at sqrt[s_{NN}]=200 GeV by the STAR experiment. Dijet structures are observed in pp, d+Au and peripheral Au+Au collisions. An additional structure is observed in central Au+Au data, signaling conical emission of correlated charged hadrons. The conical emission angle is found to be theta=1.37+/-0.02(stat)-0.07+0.06(syst), independent of p_{ perpendicular}.

Abstract
We measure directed flow (v_{1}) for charged particles in Au+Au and Cu+Cu collisions at sqrt[s_{NN}]=200 and 62.4 GeV, as a function of pseudorapidity (eta), transverse momentum (p_{t}), and collision centrality, based on data from the STAR experiment. We find that the directed flow depends on the incident energy but, contrary to all available model implementations, not on the size of the colliding system at a given centrality. We extend the validity of the limiting fragmentation concept to v_{1} in different collision systems, and investigate possible explanations for the observed sign change in v_{1}(p_{t}).

Abstract
We report precision measurements of the Feynman x (xF) dependence, and first measurements of the transverse momentum (pT) dependence, of transverse single-spin asymmetries for the production of pi0 mesons from polarized proton collisions at sqrt[s] = 200 GeV. The xF dependence of the results is in fair agreement with perturbative QCD model calculations that identify orbital motion of quarks and gluons within the proton as the origin of the spin effects. Results for the pT dependence at fixed xF are not consistent with these same perturbative QCD-based calculations.

Abstract
We report a new STAR measurement of the longitudinal double-spin asymmetry A(LL) for inclusive jet production at midrapidity in polarized p + p collisions at a center-of-mass energy of sqrt[s]=200 GeV. The data, which cover jet transverse momenta 5<p(T)<30 GeV/c, are substantially more precise than previous measurements. They provide significant new constraints on the gluon spin contribution to the nucleon spin through the comparison to predictions derived from one global fit to polarized deep-inelastic scattering measurements.

Abstract
We report the first measurement of the opening angle distribution between pairs of jets produced in high-energy collisions of transversely polarized protons. The measurement probes (Sivers) correlations between the transverse spin orientation of a proton and the transverse momentum directions of its partons. With both beams polarized, the wide pseudorapidity (-1< or = eta < or = +2) coverage for jets permits separation of Sivers functions for the valence and sea regions. The resulting asymmetries are all consistent with zero and considerably smaller than Sivers effects observed in semi-inclusive deep inelastic scattering. We discuss theoretical attempts to reconcile the new results with the sizable transverse spin effects seen in semi-inclusive deep inelastic scattering and forward hadron production in pp collisions.

Abstract
We present first measurements of the phi-meson elliptic flow (v2(pT)) and high-statistics pT distributions for different centralities from radical sNN=200 GeV Au+Au collisions at RHIC. In minimum bias collisions the v2 of the phi meson is consistent with the trend observed for mesons. The ratio of the yields of the Omega to those of the phi as a function of transverse momentum is consistent with a model based on the recombination of thermal s quarks up to pT approximately 4 GeV/c, but disagrees at higher momenta. The nuclear modification factor (R CP) of phi follows the trend observed in the K S 0 mesons rather than in Lambda baryons, supporting baryon-meson scaling. These data are consistent with phi mesons in central Au+Au collisions being created via coalescence of thermalized s quarks and the formation of a hot and dense matter with partonic collectivity at RHIC.

Abstract
Efficacy of a herbal product of E. officinalis (fruit) (EO) has been evaluated against carbon tetrachloride (CCl4) and thioacetamide (TAA) induced changes in rat liver. Chronic treatment of CCl4 and TAA revealed abnormal histopathology indicative of pre-fibrogenic events. EO reversed such alterations with significant regenerative changes suggestive of its preventive role in prefibrogenesis of liver.

Abstract
The STAR collaboration at the BNL Relativistic Heavy-Ion Collider (RHIC) reports measurements of the inclusive yield of nonphotonic electrons, which arise dominantly from semileptonic decays of heavy flavor mesons, over a broad range of transverse momenta (1.2<p(T)<10 GeV/c) in p+p, d+Au, and Au+Au collisions at sqrt[s_{NN}]=200 GeV. The nonphotonic electron yield exhibits an unexpectedly large suppression in central Au+Au collisions at high p(T), suggesting substantial heavy-quark energy loss at RHIC. The centrality and p(T) dependences of the suppression provide constraints on theoretical models of suppression.

Abstract
We present the scaling properties of Lambda, Xi, and Omega in midrapidity Au+Au collisions at the Brookhaven National Laboratory Relativistic Heavy Ion Collider at sqrt[s_{NN}]=200 GeV. The yield of multistrange baryons per participant nucleon increases from peripheral to central collisions more rapidly than that of Lambda, indicating an increase of the strange-quark density of the matter produced. The strange phase-space occupancy factor gamma_{s} approaches unity for the most central collisions. Moreover, the nuclear modification factors of p, Lambda, and Xi are consistent with each other for 2<p_{T}<5 GeV/c in agreement with a scenario of hadron formation from constituent quark degrees of freedom.

Abstract
We report a measurement of the longitudinal double-spin asymmetry A(LL) and the differential cross section for inclusive midrapidity jet production in polarized proton collisions at square root of s = 200 GeV. The cross section data cover transverse momenta 5 < pT < 50 GeV/c and agree with next-to-leading order perturbative QCD evaluations. The A(LL) data cover 5 < pT < 17 GeV/c and disfavor at 98% C.L. maximal positive gluon polarization in the polarized nucleon.

Abstract
The STAR Collaboration at the Relativistic Heavy Ion Collider reports measurements of azimuthal correlations of high transverse momentum (pT) charged hadrons in Au+Au collisions at higher pT than reported previously. As (pT) is increased, a narrow, back-to-back peak emerges above the decreasing background, providing a clear dijet signal for all collision centralities studied. Using these correlations, we perform a systematic study of dijet production and suppression in nuclear collisions, providing new constraints on the mechanisms underlying partonic energy loss in dense matter.

Abstract
Transverse momentum spectra of pi+/-, p, and p up to 12 GeV/c at midrapidity in centrality selected Au + Au collisions at square root sNN=200 GeV are presented. In central Au + Au collisions, both pi +/- and p(p) show significant suppression with respect to binary scaling at pT approximately >4 GeV/c. Protons and antiprotons are less suppressed than pi+/-, in the range 1.5 approximately < pT approximately < 6 GeV/c. The pi-/pi+ and p/p ratios show at most a weak pT dependence and no significant centrality dependence. The p/pi ratios in central Au + Au collisions approach the values in p + p and d + Au collisions at pT approximately >5 GeV/c. The results at high pT indicate that the partonic sources of pi+/-, p, and p have similar energy loss when traversing the nuclear medium.

Abstract
We report the measurements of Sigma(1385) and Lambda(1520) production in p+p and Au+Au collisions at sqrt[s{NN}]=200 GeV from the STAR Collaboration. The yields and the p(T) spectra are presented and discussed in terms of chemical and thermal freeze-out conditions and compared to model predictions. Thermal and microscopic models do not adequately describe the yields of all the resonances produced in central Au+Au collisions. Our results indicate that there may be a time span between chemical and thermal freeze-out during which elastic hadronic interactions occur.

Abstract
BACKGROUND The role of vascular endothelial growth factors (VEGFs) in intimal hyperplasia and atherogenesis remains unknown. Several studies have suggested that some members of the VEGF family reduce intimal hyperplasia, but others have proposed that VEGFs accelerate restenosis and atherosclerosis. This investigation conducted a comparative study with adenoviruses encoding different VEGFs in a rabbit carotid artery collar model of intimal hyperplasia in order to analyze the role of VEGFs in the formation of intimal hyperplasia. MATERIALS AND METHODS Intimal hyperplasia was induced in the carotid arteries of cholesterol fed New Zealand White rabbits using a silastic collar. Adenoviral vectors encoding VEGF-A, VEGF-B, VEGF-C, VEGF-C(DeltaNDeltaC), VEGF-D and VEGF-D(DeltaNDeltaC) were delivered to the adventitia using the collar as a gene delivery device. Adeno-LacZ was used as a control. RESULTS A significant (P < 0.01) increase in the intima/media ratio was observed in the arteries transduced with VEGF-A, VEGF-D and VEGF-D(DeltaNDeltaC). There was a significant increase in the number of proliferating cells in the adventitia, media and intima of the VEGF-A, VEGF-D and the VEGF-D(DeltaNDeltaC) transduced arteries. The majority of medial smooth muscle cells in these arteries had a synthetic phenotype. The presence of matrix metalloproteinase-2 (MMP-2) and MMP-9 in the VEGF-A, VEGF-D and the VEGF-D(DeltaNDeltaC) transduced arteries was significantly increased. A significant positive correlation was observed between adventitial angiogenesis and intimal hyperplasia. CONCLUSIONS Adventitial delivery of adenoviruses encoding VEGF-A, VEGF-D and VEGF-D(DeltaNDeltaC) increased intimal hyperplasia in the rabbit collar model. Adventitial angiogenesis correlated positively with the intimal hyperplasia. These results indicated that efficient adventitial production of VEGF-A, VEGF-D and VEGF-D(DeltaNDeltaC) can cause thickening of the inner layer of the artery in rabbits.

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
OBJECTIVE Fine needle aspiration cytology (FNAC) in combination with radiological examination has recently gained clinical recognition for evaluating skeletal lesions. We evaluated our experience with the use of FNA in diagnosing bone lesions with emphasis on areas of difficulty and limitations. MATERIALS AND METHODS Over a period of 5 years FNA was performed in 66 cases of bone lesions. Aspirations were done by cytopathologists using 22-gauge needle. Out of 66 cases unsatisfactory aspirate was obtained in 12 cases. Cytohistological correlation was available in 19 cases. RESULTS Adequate aspirates were categorized into neoplastic (27 cases) and non-neoplastic (27 cases) lesions. Of the 27 neoplastic aspirates, 20 were malignant (12 primary, 8 metastatic deposits) and 7 were benign. In the malignant group osteosarcoma was correctly diagnosed in 3 cases while other 3 were labeled as sarcoma NOS because of lack of osteoid. Metastatic deposits were sub-typed in 6 cases; from renal cell carcinoma (3 cases), proststic adenocarcinoma, follicular carcinoma thyroid, and squamous cell carcinoma. Neoplastic group comprised of 6 cases of cysts and 21 cases of chronic osteomyelitis. Thirteen cases were diagnosed as tuberculous osteomyelitis. CONCLUSIONS FNA is a frequent indication in metastases in the bone where distinct cytologic features can even identify an unknown primary. However, diagnosis of primary tumours of the bone is limited by precise subtyping of the tumours. FNA has emerged as a cost effective tool for initial diagnosis of both neoplastic and non-neoplastic lesions of the bone.

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.
