Nonparametric density estimation from data with a mixture of Berkson and classical errors
Authors: Delaigle Aurore 
Published: January 2010

AbstractThe author considers density estimation from contaminated data where the measurement errors come from two very different sources. A first error, of Berkson type, is incurred before the experiment: the variableXof interest is unobservable and only a surrogate can be measured. A second error, of classical type, is incurred after the experiment: the surrogate can only be observed with measurement error. The author develops two nonparametric estimators of the density ofX, valid whenever Berkson, classical or a mixture of both errors are present. Rates of convergence of the estimators are derived and a fully data‐driven procedure is proposed. Finite sample performance is investigated via simulations and on a real data example.
Marginally restricted sequential D‐optimal designs
Authors: López‐Fidalgo Jesús , Martín‐Martín Raul , Wiens Douglas P. 
Published: January 2010

AbstractIn many experiments, not all explanatory variables can be controlled. When the units arise sequentially, different approaches may be used. The authors study a natural sequential procedure for “marginally restricted” D‐optimal designs. They assume that one set of explanatory variables (x1) is observed sequentially, and that the experimenter responds by choosing an appropriate value of the explanatory variable x2. In order to solve the sequential problem a priori, the authors consider the problem of constructing optimal designs with a prior marginal distribution for x1. This eliminates the influence of units already observed on the next unit to be designed. They give explicit designs for various cases in which the mean response follows a linear regression model; they also consider a case study with a nonlinear logistic response. They find that the optimal strategy often consists of randomizing the assignment of the values of x2.
On diagnostic checking of the autoregressive conditional intensity model
Authors: Kwok Sai Man Simon , Li Wai Keung 
Published: January 2010

AbstractThe autoregressive conditional intensity model proposed by Russell (1998) is a promising option for fitting multivariate high frequency irregularly spaced data. The authors acknowledge the validity of this model by showing the independence of its generalized residuals, a crucial assumption of the model formulation not readily recognized by researchers. The authors derive the large‐sample distribution of the autocorrelations of the generalized residual series and use it to construct a goodness‐of‐fit test for the model. Empirical results compare the performance of their test with other off‐the‐shelf tests such as the Ljung–Box test. They illustrate the use of their test with transaction records of the HSBC stock.
Weighted quantile regression with nonelliptically structured covariates
Authors: Salibián‐Barrera Matías , Wei Ying 
Published: January 2010

AbstractAlthough quantile regression estimators are robust against low leverage observations with atypically large responses (Koenker & Bassett 1978), they can be seriously affected by a few points that deviate from the majority of the sample covariates. This problem can be alleviated by downweighting observations with high leverage. Unfortunately, when the covariates are not elliptically distributed, Mahalanobis distances may not be able to correctly identify atypical points. In this paper the authors discuss the use of weights based on a new leverage measure constructed using Rosenblatt's multivariate transformation which is able to reflect nonelliptical structures in the covariate space. The resulting weighted estimators are consistent, asymptotically normal, and have a bounded influence function. In addition, the authors also discuss a selection criterion for choosing the downweighting scheme. They illustrate their approach with child growth data from Finland. Finally, their simulation studies suggest that this methodology has good finite‐sample properties.

AbstractBACKGROUND:The incidence of pelvic fractures and associated risk factors was determined in women treated with curative‒intent radiotherapy for cervical cancer.METHODS:The records of 516 women treated with curative‒intent radiotherapy for cervical cancer between 2001 and 2006 at the University of Texas M. D. Anderson Cancer Center were reviewed. Among these, 300 patients had at least 1 post‐treatment computed tomography scan or magnetic resonance imaging study available for review, and they comprised our study population. All imaging studies were re‐reviewed by a single radiologist to evaluate for fractures.RESULTS:Pelvic fractures were noted in 29 of 300 patients (9.7%). Fracture sites included sacrum (n = 24; 83%), sacrum and pubis (n = 3; 10%), iliac crest (n = 1; 3%), and sacrum and acetabulum (n = 1; 3%). Thirteen patients (45%) were symptomatic, with pain being the most common presenting symptom. The median time from the completion of radiotherapy to the detection of fractures on imaging studies was 14.1 months (range, 2.1‐63.1 months), with 38% of patients diagnosed within 1 year and 83% diagnosed within 2 years of completing therapy. The median age of the patients at diagnosis was higher in the women who developed a fracture compared with the women who did not (56.5 years vs 46.7 years; P = .04). A higher number of women with a fracture were postmenopausal (62% vs 37%; P = .03). The median body mass index was lower in the women who had a fracture (26.0 kg/m2 vs 28.0 kg/m2; P = .03).CONCLUSIONS:Pelvic fractures were detected in a substantial proportion of women after radiotherapy for cervical cancer. Bone mineral density screening and pharmacologic intervention should be considered in these women. Cancer 2010. © 2010 American Cancer Society.

Published: January 2010

AbstractBACKGROUND:Primary gliosarcoma (PGS) is a rare central nervous system tumor with limited experience reported in the literature. In the current study, the authors present a modern series of confirmed PGS cases treated in the era of magnetic resonance imaging (MRI), after the accepted glioblastoma management of resection, radiation, and temozolomide.METHODS:Using a retrospective review, patients with confirmed PGS were identified (1996‐2008). Cases were determined to be PGS by central pathology review using the 2007 World Health Organization criteria. Extensive chart review was performed to gather clinical and pathologic data on these cases.RESULTS:All but 1 patient had undergone a preoperative MRI, with 1 patient receiving a computed tomography scan due to a cardiac pacemaker. A total of 10 patients received radiotherapy with concurrent and adjuvant temozolomide chemotherapy, and 8 patients received radiotherapy alone or in combination with other chemotherapeutic agents. In 2 patients, the history of adjuvant treatment could not be confirmed. The overall median survival was 13.9 months (range, 2.2‐22.9 months). Patients with gliosarcomas resembling meningioma were found to have a significantly prolonged median survival compared with patients harboring gliosarcoma resembling glioblastoma multiforme (16 months vs 9.6 months; P = .011). However, no difference in survival was noted between patients who received concurrent radiotherapy and temozolomide compared with those who did not (10.4 months vs 13.9 months; P = .946).CONCLUSIONS:The results of the current study support previous hypotheses that there are 2 distinct types of PGS. The type mimicking the appearance of a meningioma appears to carry a significantly more favorable prognosis, most likely due to an increased chance at achieving macroscopic total resection.

Antiangiogenesis agents in the treatment of soft tissue sarcomas
Authors: Ganjoo Kristen , Jacobs Charlotte 
Published: January 2010

AbstractSoft tissue sarcomas (STSs) are a heterogeneous group of malignancies that includes >50 different subtypes, each with unique clinical and pathologic qualities. In general, there is a 50% cure rate, and most cures are achieved with complete surgical resection with or without radiation therapy. The results from chemotherapeutic agents for unresectable or metastatic disease have been disappointing with minimal long‐term benefit. New targeted and novel agents are needed to improve response and survival. Tumor angiogenesis has been an intense focus in cancer therapy over the past decade. Several of numerous antiangiogenesis agents have been developed, and many already have been approved for the treatment of both solid and liquid tumors. Certain STSs are highly vascular tumors that often demonstrate angiogenesis markers. The objective of this review was to evaluate these angiogenesis markers in defining the role of angiogenesis in the treatment of patients with STS. In addition, the authors conducted an in‐depth review of the results from using key antiangiogenesis agents in the treatment of STS. Cancer 2010. © 2010 American Cancer Society.
Ethnic and racial differences in patients with Ewing sarcoma
Authors: Worch Jennifer , Matthay Katherine K. , Neuhaus John , Goldsby Robert , DuBois Steven G. 
Published: January 2010

AbstractBACKGROUND:Ewing sarcoma (ES) was a malignant tumor of bone or soft tissue. One of the few risk factors for developing ES is race, with a higher incidence noted in populations of European rather than African or Asian ancestry. The goal of the current study was to evaluate racial and ethnic differences in presentation and overall survival (OS) among patients diagnosed with ES before age 40 years.METHODS:Data from the Surveillance, Epidemiology, and End Results database identified 1715 patients aged <40 years who were diagnosed with ES between 1973 and 2005. Racial and ethnic group differences were compared using chi‐square tests. OS was estimated by Kaplan‐Meier analysis and compared using log‐rank tests and Cox models.RESULTS:Black patients had significantly more soft‐tissue tumors compared with white non‐Hispanic patients (P <.0001). Asian and white Hispanic patients were found to have an intermediate frequency of soft‐tissue tumors that also differed from white non‐Hispanic patients (P <.0001). White Hispanic patients presented with a higher proportion of larger tumors compared with white non‐Hispanic patients (P = .042). Black patients tended to be older than white non‐Hispanic patients (P = .012). Sex, frequency of pelvic tumors, and metastatic status did not appear to differ by ethnicity or race. OS was found to differ according to race and ethnicity. Even after controlling for known confounders, OS was significantly worse for black, Asian, and white Hispanic patients compared with white non‐Hispanic patients (P = .0031, P = .0182, and P = .0051, respectively).CONCLUSIONS:Ethnic and racial differences in characteristics and outcomes of patients with ES do exist. Understanding the etiology of these differences will require further study. Cancer 2010. © 2010 American Cancer Society.

AbstractObjectiveThis paper examined the 12‐month rate of mental disorders and subsequent service use among Canadian seniors aged 65–79 and 80 and over and adults aged 20–49 and 50–64.MethodsThis is a secondary analysis of data [n = 33 695] of the population‐based Canadian Community Health survey, Cycle 1.2 (CCHS 1.2). Major Depressive Episodes (MDEs), specific Anxiety Disorders (AD) and Alcohol Abuse/Dependence rates were assessed.ResultsThe 12‐month rates for the two senior groups aged 65–79 and 80+ for MDEs, ADs, and Substance Dependence (SD) are 1.7% and 1.6%; 1.4% and 0.8%; and 0.1% and 0.0%, respectively. Seniors aged 65–79 and 80+ had significantly lower rates than adults aged 20–49 and 50–64 for all mental disorders and SD. Among the total sample, seniors aged 65–79 and 80+ had significantly lower utilization rates than adults aged 20–49 and 50–64 for all three provider categories (GP only, GP and Other Health Professional, Any Other Health Professional but GP). Females aged 65–79 and 80+ were less likely to have reported service use for mental health reasons as opposed to those females aged 20–49 and 50–64. Males aged 65–79 and 80+ were more likely to have reported having used mental health services in the past 12 months as opposed to males aged 20–49 and 50–64.ConclusionsThe presence of common mental disorders is lower in seniors as compared to younger adults. Age and gender influence mental health service utilization rates. Copyright © 2010 John Wiley & Sons, Ltd.

Published: January 2010

AbstractBackgroundAn improvement of retroviral infection has been postulated using a naturally occurring fragment of the abundant semen marker prostatic acidic phosphatase. This peptide, termed semen‐derived enhancer of virus infection (SEVI), promotes HIV attachment to the target cells.MethodsIn the present study, we examined whether SEVI would also enhance the infectivity of other viruses with different envelope proteins. We focused on retroviruses pseudotyped with envelopes that are commonly used for the genetic modification of cells, in particular, T cells and hematopoietic progenitor cells. Because the effect of SEVI is considered to be a result of its cationic properties, we compared SEVI with other cationic agents such as protamine sulfate and Polybrene.ResultsWe found that SEVI increases the efficiency of gene transfer for lentiviral and gammaretroviral vector constructs pseudotyped with VSV‐G, GALV, RD114 or foamy viral envelopes on hematopoietic and nonhematopoietic cell lines. On T cells, the transduction efficiency of GALV and RD114 pseudotyped vectors was significantly increased by SEVI. A significant increase of the gene transfer rate was also detected for foamy virally pseudotyped lentivirus on murine hematopoietic progenitor cells. No toxic effect of SEVI treatment was detected on any cell type tested, including human and murine hematopoietic stem/progenitor cells. When directly comparing the effect of SEVI with Polybrene or protamine sulfate, we show that the semen‐derived protein is more efficient in increasing the gene transfer rate.ConclusionsSEVI is a promising agent for promoting and improving gene transfer and may also be useful for clinical gene therapy studies.

Abstract
magnified imageCarbodiimide, obtained from aza‐Wittig reaction of iminophosphorane with 4‐fluorophenyl isocyanate, reacted with various nucleophiles under mild conditions to give a series of 2‐substituted‐3‐(4‐fluorophenyl)‐benzofuro [3,2‐d] pyrimidin‐4(3H)‐ones in satisfactory yield. Their structures were confirmed using NMR, EI‐Ms, IR, and elementary analysis, and compound 7b was further analyzed by single‐crystal. The preliminary bioassays indicated that these compounds showed moderate fungicidal activities against six kinds of fungi at a concentration of 50 mg/L. J. Heterocyclic Chem., 2010.

Published: January 2010

AbstractWe report the surface‐enhanced Raman scattering (SERS) effect from the apex of single‐crystalline Ag nanowires (NWs). We also fabricated tip‐enhanced Raman spectroscopy (TERS) tips by attaching individual Ag NWs to W wires by using the alternating current dielectrophoresis (AC‐DEP) method. The single‐crystalline Ag NW tips could overcome many of the shortcomings of conventional TERS tips. Most importantly, the results obtained from TERS using single‐crystalline metal NWs are very reproducible, and the tips are also reusable. This development represents a significant progress in making TERS a reliable optical characterization technique with nanometer spatial resolution. Copyright © 2010 John Wiley & Sons, Ltd.
Detection and analysis of cyclotrimethylenetrinitramine (RDX) in environmental samples by surface‐enhanced Raman spectroscopy
Authors: Hatab Nahla A. , Eres Gyula , Hatzinger Paul B. , Gu Baohua 
Published: January 2010

AbstractTechniques for rapid and sensitive detection of energetics such as cyclotrimethylenetrinitramine (RDX) are needed both for environmental and security screening applications. Here we report the use of surface‐enhanced Raman scattering (SERS) spectroscopy to detect traces of RDX with good sensitivity and reproducibility. Using gold (Au) nanoparticles (∼90–100 nm in diameter) as SERS substrates, RDX was detectable at concentrations as low as 0.15 mg/l in a contaminated groundwater sample. This detection limit is about two orders of magnitude lower than those reported previously using SERS techniques. A surface enhancement factor of ∼6 × 104 was obtained. This research further demonstrates the potential for using SERS as a rapid, in situ field screening tool for energetics detection when coupled with a portable Raman spectrometer.
