Real‐time identification of traffic conditions prone to injury and non‐injury crashes on freeways using genetic programming
Authors: Xu Chengcheng , Liu Pan , Wang Wei , Zhang Yin 
Published: March 2016

SummaryThis study applied the genetic programming (GP) model to identify traffic conditions prone to injury and property‐damage‐only (PDO) crashes in different traffic states on freeways. It was found that the traffic conditions prone to injury and PDO crashes can be classified into a high‐speed and a low‐speed traffic state. The random forest (RF) analyses were conducted to identify the contributing factors to injury and PDO crashes in these two traffic states. Four separate GP models were then developed to link the risks of injury and PDO crashes in two traffic states to the variables selected by the RF. An overall GP model was also developed for the combined dataset. It was found that the separate GP models that considered different traffic states and crash severity provided better predictive performance than the overall model, and the traffic flow variables that affected injury and PDO crashes were quite different across different traffic states. The proposed GP models were also compared with the traditional logistic regression models. The results suggested that the GP models outperformed the logistic regression models in terms of the prediction accuracy. More specifically, the GP models increased the prediction accuracy of injury crashes by 10.7% and 8.0% in the low‐speed and high‐speed traffic states. For PDO crashes, the GP models increased the prediction accuracy by 7.4% and 6.0% in the low‐speed and high‐speed traffic states. Copyright © 2016 John Wiley & Sons, Ltd.
Review: The HSP90 molecular chaperone—an enigmatic ATPase
Authors: Pearl Laurence H. 
Published: March 2016

ABSTRACTThe HSP90 molecular chaperone is involved in the activation and cellular stabilization of a range of ‘client’ proteins, of which oncogenic protein kinases and nuclear steroid hormone receptors are of particular biomedical significance. Work over the last two decades has revealed a conformational cycle critical to the biological function of HSP90, coupled to an inherent ATPase activity that is regulated and manipulated by many of the co‐chaperones proteins with which it collaborates. Pharmacological inhibition of HSP90 ATPase activity results in degradation of client proteins in vivo, and is a promising target for development of new cancer therapeutics. Despite this, the actual function that HSP90s conformationally‐coupled ATPase activity provides in its biological role as a molecular chaperone remains obscure. © 2016 Wiley Periodicals, Inc.

AbstractRadioimmunotherapy (RIT) after an induction phase with conventional chemoimmunotherapy became an attractive strategy of consolidation for patients with advanced follicular lymphoma: in particular, in many studies RIT was represented by yttrium‐90‐ibritumomab tiuxetan (90Y‐IT). Independently by the different front‐line treatment, updates on the long‐term follow‐up of these studies are needed because the disease course of follicular lymphoma is characterised by multiple relapses and progressively shorter durations of response. We report updated long‐term efficacy and toxicity results of a multicenter phase II study on sequential treatment with four cycles of fludarabine, mitoxantrone, and rituximab followed by 90Y‐IT as front‐line therapy for untreated patients with intermediate/high‐risk follicular lymphoma. With a median follow‐up of 84 months, only 19/49 (38.8%) complete response patients relapsed, yielding an estimated long‐term disease‐free survival of 62.6%. The 7‐year overall survival was 72.7%. Four (7.3%) second acute myeloid leukemia occurred, with a median time following RIT of 42 months. A relevant patients' responsiveness to subsequent therapies occurred: approximately 65% of relapsed patients obtained a good clinical response after the second‐line treatment. These data represented the first evidence of a real role even in the long period of 90Y‐IT after a fludarabine‐containing regimen plus rituximab in the treatment of high‐risk follicular lymphoma.

AbstractThe purpose of this study was to identify the optimal local treatment modalities for International Federation of Gynecology and Obstetrics (FIGO) stage I‐II small‐cell carcinoma of the cervix (SCCC), including cancer‐directed surgery (CDS) and/or radiotherapy (RT). The Surveillance Epidemiology and End Results (SEER) database was used to identify SCCC patients from 1988 to 2012, and analyzed using Kaplan–Meier survival and Cox regression proportional hazard methods to determine factors significant for cause‐specific survival (CSS) and overall (OS). A total of 208 patients of SCCC were enrolled. The median follow‐up time was 31 months. Fifty‐eight (27.9%) patients were treated with primary CDS, 88 (42.3%) patients underwent CDS combined with RT, and 62 (29.8%) patients were treated with primary RT. Univariate and multivariate analyses showed that local treatment modalities were independent prognostic factors for CSS and OS. Patients who had undergone CDS had better CSS and OS, compared with patients who had been treated with combined CDS and RT or RT alone. The 5‐year CSS and OS of entire group was 49.8% and 46.4%, respectively. The 5‐year CSS in the groups of patients receiving CDS, CDS combined with RT, and RT alone were 67.9%, 49.7%, and 32.6%, respectively (P < 0.001). The 5‐year OS in patients treated with CDS, CDS combined with RT, and RT alone were 64.9%, 46.2%, and 28.8% (P < 0.001). Primary surgery was associated with improved CSS and OS for FIGO stage I and lymph node negative disease. Primary surgery is the most effective local treatment for FIGO stage I‐II SCCC, as adjuvant RT or radical RT does not improve survival compared to radical surgery, especially in patients with FIGO stage I and lymph node negative disease.
The Conformational Variability of FimH: Which Conformation Represents the Therapeutic Target?

Published: March 2016

AbstractFimH is a bacterial lectin found at the tips of type 1 pili of uropathogenic Escherichia coli (UPEC). It mediates shear‐enhanced adhesion to mannosylated surfaces. Binding of UPEC to urothelial cells initiates the infection cycle leading to urinary tract infections (UTIs). Antiadhesive glycomimetics based on α‐d‐mannopyranose offer an attractive alternative to the conventional antibiotic treatment because they do not induce a selection pressure and are therefore expected to have a reduced resistance potential. Genetic variation of the fimH gene in clinically isolated UPEC has been associated with distinct mannose binding phenotypes. For this reason, we investigated the mannose binding characteristics of four FimH variants with mannose‐based ligands under static and hydrodynamic conditions. The selected FimH variants showed individually different binding behavior under both sets of conditions as a result of the conformational variability of FimH. Clinically relevant FimH variants typically exist in a dynamic conformational equilibrium. Additionally, we evaluated inhibitory potencies of four FimH antagonists representing different structural classes. Inhibitory potencies of three of the tested antagonists were dependent on the binding phenotype and hence on the conformational equilibrium of the FimH variant. However, the squarate derivative was the notable exception and inhibited FimH variants irrespective of their binding phenotype. Information on antagonist affinities towards various FimH variants has remained largely unconsidered despite being essential for successful antiadhesion therapy.

Key Clinical MessagePosterior interosseous neuropathy should be considered in patients presenting with finger and wrist drop and no sensory deficit. Clinical and electrophysiological assessments are key to a diagnosis. MRI may disclose etiological information not available to clinical or neurophysiological assessment, and should be thought as a complementary diagnostic tool.
Kinetic Modeling of Dunaliella tertiolecta Growth under Different Nitrogen Concentrations

Published: March 2016

AbstractMathematical models are presented to describe the relationship between nitrogen consumption, biomass growth, and carotenoid production by the microalgae Dunaliella tertiolecta BE 003 grown under nitrogen‐limited and nonlimited conditions. The nitrogen uptake was modeled by an n‐order nitrogen‐catalyzed reaction. Three different expressions were proposed for the biomass‐specific growth rate. Carotenoid production was fitted using the Luedeking‐Piret equation. The nitrogen‐catalyzed expression proved to be adequate to model nitrogen uptake by D. tertiolecta over a wide range of nitrogen concentrations. Biomass expression must be improved to describe the cessation of growth when nitrogen is still available in the cultures. The Luedeking‐Piret expression successfully modeled the carotenoid production.
Intrinsic Iron‐Containing Multiwalled Carbon Nanotubes as Electro‐Fenton Catalyst for the Conversion of Benzene to Redox‐Active Surface‐Confined Quinones
Authors: Vishnu Nandimalla , Kumar Annamalai Senthil 
Published: March 2016

AbstractMultiwalled carbon nanotubes containing an iron impurity (2.1 wt %) (MWCNT‐Fe*) were used to modify a glassy carbon electrode (GCE/MWCNT‐Fe*), which was subsequently exploited for the electrochemical oxidation of benzene (BZ) to redox‐active and surface‐confined quinones (BZO) in H2O2 containing pH 2 HCl–KCl. Physicochemical and electrochemical characterization methods, such as transmission electron microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, UV/Vis spectroscopy, liquid chromatography coupled mass spectroscopy, and cyclic voltammetry studies with naked Fe3+/2+, catechol (CA), and hydroquinone (HQ), evidenced that, in the presence of H2O2, the intrinsic iron impurity in MWCNT‐Fe* follows the electro‐Fenton reaction to oxidize BZ to BZO (CA+HQ) on the surface of MWCNT‐Fe* (i.e. GCE/MWCNT‐Fe*@BZO). Electro‐catalytic oxidation of hydrazine was demonstrated as a model system for the application of the GCE/MWCNT‐Fe*@BZO catalyst.
