Influence of infrastructure on water quality and greenhouse gas dynamics in urban streams
Authors: Smith Rose M. , Kaushal Sujay S. , Beaulieu Jake J. , Pennino Michael J. , Welty Claire 
Published: June 2017

Abstract. Streams and rivers are significant sources of nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) globally, and watershed management can alter greenhouse gas (GHG) emissions from streams. We hypothesized that urban infrastructure significantly alters downstream water quality and contributes to variability in GHG saturation and emissions. We measured gas saturation and estimated emission rates in headwaters of two urban stream networks (Red Run and Dead Run) of the Baltimore Ecosystem Study Long-Term Ecological Research project. We identified four combinations of stormwater and sanitary infrastructure present in these watersheds, including: (1) stream burial, (2) inline stormwater wetlands, (3) riparian/floodplain preservation, and (4) septic systems. We selected two first-order catchments in each of these categories and measured GHG concentrations, emissions, and dissolved inorganic and organic carbon (DIC and DOC) and nutrient concentrations biweekly for 1 year. From a water quality perspective, the DOC : NO3− ratio of streamwater was significantly different across infrastructure categories. Multiple linear regressions including DOC : NO3− and other variables (dissolved oxygen, DO; total dissolved nitrogen, TDN; and temperature) explained much of the statistical variation in nitrous oxide (N2O, r2 =  0.78), carbon dioxide (CO2, r2 =  0.78), and methane (CH4, r2 =  0.50) saturation in stream water. We measured N2O saturation ratios, which were among the highest reported in the literature for streams, ranging from 1.1 to 47 across all sites and dates. N2O saturation ratios were highest in streams draining watersheds with septic systems and strongly correlated with TDN. The CO2 saturation ratio was highly correlated with the N2O saturation ratio across all sites and dates, and the CO2 saturation ratio ranged from 1.1 to 73. CH4 was always supersaturated, with saturation ratios ranging from 3.0 to 2157. Longitudinal surveys extending form headwaters to third-order outlets of Red Run and Dead Run took place in spring and fall. Linear regressions of these data yielded significant negative relationships between each gas with increasing watershed size as well as consistent relationships between solutes (TDN or DOC, and DOC : TDN ratio) and gas saturation. Despite a decline in gas saturation between the headwaters and stream outlet, streams remained saturated with GHGs throughout the drainage network, suggesting that urban streams are continuous sources of CO2, CH4, and N2O. Our results suggest that infrastructure decisions can have significant effects on downstream water quality and greenhouse gases, and watershed management strategies may need to consider coupled impacts on urban water and air quality.

Published: June 2017

Introduction: Prostate vaporization technology is becoming a standard of care for treatment of moderate, symptomatic benign prostatic hyperplasia (BPH). We compared two transurethral prostatevaporization technologies with respect to cost, efficiency, efficacy, safety, and surgical team satisfaction.Methods: Fifty-five patients meeting standardized symptom criteria for BPH were randomized to either Olympus Plasma ButtonTM or Biolitec EVOLVE® diode laser vaporization. Primary outcome of cost with secondary outcomes of clinical efficacy, resection time, surgical team satisfaction, and safety were analyzed. Followup was carried out at six and 12 weeks. Patient factors included baseline, as well as six- and 12-week International Prostate Symptom Score (IPSS) with quality of life (QoL) scores. We recorded surgical team satisfaction with a Likert-style survey investigating ease of set-up, reliability, efficiency, and ability to reach desired endpoint. All complications or side effects detected within three months and the resulting management were included in the cost analysis.Results: Mean cost per patient was $3418 for the Olympus group and $4564 for Biolitec (p<0.05). Surgical vaporization time was significantly less for the Olympus group, 24.3 vs. 33.5 minutes(p<0.05). Surgical and nursing staff preferred the Olympus device (p<0.05). IPPS symptom improvement and complication rates were similar between groups. Patients in the Biolitec arm had more intraoperative bleeding episodes requiring conversion to monopolar transurethral resection of the prostate (TURP) (three vs. none).Conclusions: In a head-to-head randomized trial, Olympus Plasma Button transurethral vaporization was more cost-effective, faster, and preferred by surgical staff when compared to Biolitetec Diode Laser vaporization. Both devices showed similar safety and efficacy.
Advances in basic science methodologies for clinical diagnosis in female stress urinary incontinence

Published: June 2017

We provide an overview of advanced imaging techniques currently being explored to gain greater understanding of the complexity of stress urinary incontinence (SUI) through better definition of structural anatomic data. Two methods of imaging and analysis are detailed for SUI with or without prolapse: (1) open magnetic resonance imaging with or without the use of reference lines, and (2) 3D reconstruction of the pelvis using MRI. An additional innovative method of assessment includes the use of near infrared spectroscopy (NIRS), which uses noninvasive photonics in a vaginal speculum to objectively evaluate pelvic floor muscle (PFM) function as it relates to SUI pathology. Advantages and disadvantages of these techniques are described. The recent innovation of open-configuration magnetic resonance imaging allows images to be captured in sitting and standing positions, which better simulates states that correlate with urinary leakage and can be further enhanced with 3D reconstruction. By detecting direct changes in oxygenated muscle tissue, the NIRS vaginal speculum is able to provide insight into how the oxidative capacity of the PFM influences SUI. The small number of units able to provide patient evaluation using these techniques and their cost and relative complexity are major considerations, but if such imaging can optimize diagnosis, treatment allocation, and selection for surgery enhanced imaging techniques may prove to be a worthwhile and cost-effective strategy for assessing and treating SUI.
Diagnostic Algorithm of Common Mature B-Cell Lymphomas by Immunohistochemistry
Authors: Wang Huan-You , Zu Youli 
Published: June 2017

Context.—Different types of mature B-cell lymphomas, including plasma cell neoplasms, exhibit distinct immunohistochemical profiles, which enable them to be correctly diagnosed. However, except for rare examples of lymphoma-specific immunohistochemistry, such as cyclin D1 in mantle cell lymphoma and annexin A1 in hairy cell leukemia, immunohistochemical profiles of mature B-cell lymphomas overlap and lack specificity.Objectives.—To systemically review immunohistochemical features associated with commonly encountered mature B-cell lymphomas based on the presence or absence of CD5 and CD10; to review the immunophenotypic profile of plasma cells derived from plasma cell myelomas and B-cell lymphomas; and to review a group of rare, aggressive B-cell lymphomas with antigen expression features of plasma cells.Data Sources.—Published and PubMed-indexed English literature was reviewed.Conclusions.—Although the presence or absence of CD5 and CD10 expression should be included in the initial immunohistochemistry screening panel for mature B-cell lymphomas, appropriate and judicial use of other B-cell antigens is necessary to ensure correct diagnoses. Furthermore, although the status of CD5 and CD10 expression is associated with certain prototypes of B-cell lymphomas, their expression is not specific. Plasma cells from plasma cell neoplasias and B-cell lymphomas exhibit overlapping but relatively distinct immunophenotypes; thus, a panel of immunohistochemical markers (CD19, CD45, CD56, and CD117) can be employed for their proper identification. Lastly, CD138 staining results are almost always positive in a group of aggressive B-cell lymphomas with plasmablastic features, including plasmablastic plasma cell myeloma, plasmablastic lymphoma, and ALK-1+ large B-cell lymphoma.
Les consommateurs perçoivent-ils le prix des produits du commerce équitable comme étant juste ?
Authors: Dekhili Sihem , Coulibaly Mantiaba , Dufeu Ivan 
Published: June 2017

Le principe de prix juste constitue l’un des piliers du commerce équitable (CE) depuis ses origines. Dans la littérature, cette question est généralement abordée sous l’angle des producteurs, avec le regard de l’analyste ou du chercheur : sont-ils rémunérés correctement pour leur travail ? La présente recherche, qui s’appuie sur des entretiens menés auprès de consommateurs français, se propose d’explorer la justice liée au prix en se plaçant de leur point de vue : le prix qu’ils paient pour les produits issus du CE leur semble-t-il juste ? En nous appuyant sur la théorie de l’équité, nous avons observé que les individus, dans leur perception de la justice liée au prix, ne mobilisent pas de mécanisme comparatif. Ils adoptent souvent des discours qui relèvent des principes de la justice distributive au sens d’Aristote en s’intéressant notamment à la répartition des prix et des marges dans les filières de CE. Dans ce contexte, la perception de la justice liée au prix est conditionnée par la confiance accordée aux organisations intervenant dans ces filières.

Published: June 2017

Dans cet article nous développons une recherche approfondie sur les déterminants de la motivation entrepreneuriale des mampreneurs en contexte français.Les résultats de notre étude montrent que les dimensions motivationnelles des mampreneurs françaises sont diverses et non mutuellement exclusives. Au-delà de la conciliation travail-famille, la recherche de satisfaction, d’indépendance et de reconnaissance professionnelle sont des facteurs importants de motivation entrepreneuriale pour ces mères entrepreneures. Ils sont cependant conditionnés par des facteurs contextuels perçus au moment de la décision de création et qui sont susceptibles d’évoluer dans le temps. Cet article propose alors un modèle de la motivation entrepreneuriale des mampreneurs qui inclut la prise en compte de différentes strates motivationnelles qui combinent des facteurs psychologiques, économiques et environnementaux.

Tuberculous pericarditis
Authors: Kutoloski Karen S. , Salvucci Thomas J. , Dennis Charles 
Published: June 2017

Abstract
A patient with a 5-month history of pericardial effusion and unsuccessful steroid treatment was found at pericardial exploration to have thickened pericardium adhered to the heart. After anterior pericardiectomy, histologic examination revealed severe granulomatous pericarditis resulting from infection with Mycobacterium tuberculosis. Despite the pericardiectomy and antituberculous therapy, the patient continued to have symptoms, including bilateral pleural effusions, 4 days after discharge from the hospital. After a second exploration (after echocardiography revealed decreased left ventricular function and hemodynamic findings showed persistent constriction), anterior and posterior cardiectomy was deemed necessary. Pleural effusion did not recur, and the patient was discharged with antituberculous drug therapy. This rare extrapulmonary form of tuberculosis can have an insidious or sudden onset, and diagnosis is complicated by false-negative tuberculin tests, nonspecific radiographic and echocardiographic findings, and timeconsuming bacteriologic culture. Previous high mortality with the disease has been decreased to approximately 40% by the advent of antituberculous drug therapy. The still significant mortality reflects the difficulty in early diagnosis and the serious effects of pericardial effusion and constriction.
Phenotypic variation in dorsal fin morphology of coastal bottlenose dolphins (Tursiops truncatus) off Mexico

Published: June 2017

Geographic variation in external morphology is thought to reflect an interplay between genotype and the environment. Morphological variation has been well-described for a number of cetacean species, including the bottlenose dolphin (Tursiops truncatus). In this study we analyzed dorsal fin morphometric variation in coastal bottlenose dolphins to search for geographic patterns at different spatial scales. A total of 533 dorsal fin images from 19 available photo-identification catalogs across the three Mexican oceanic regions (Pacific Oceann = 6, Gulf of Californian = 6 and, Gulf of Mexicon = 7) were used in the analysis. Eleven fin shape measurements were analyzed to evaluate fin polymorphism through multivariate tests. Principal Component Analysis on log-transformed standardized ratios explained 94% of the variance. Canonical Discriminant Function Analysis on factor scores showed separation among most study areas (p < 0.05) with exception of the Gulf of Mexico where a strong morphometric cline was found. Possible explanations for the observed differences are related to environmental, biological and evolutionary processes. Shape distinction between dorsal fins from the Pacific and those from the Gulf of California were consistent with previously reported differences in skull morphometrics and genetics. Although the functional advantages of dorsal fin shape remains to be assessed, it is not unlikely that over a wide range of environments, fin shape may represent a trade-off among thermoregulatory capacity, hydrodynamic performance and the swimming/hunting behavior of the species.
Discrimination factors of carbon and nitrogen stable isotopes in meerkat feces
Authors: Montanari Shaena 
Published: June 2017

Stable isotope analysis of feces can provide a non-invasive method for tracking the dietary habits of nearly any mammalian species. While fecal samples are often collected for macroscopic and genetic study, stable isotope analysis can also be applied to expand the knowledge of species-specific dietary ecology. It is somewhat unclear how digestion changes the isotope ratios of animals’ diets, so more controlled diet studies are needed. To date, most diet-to-feces controlled stable isotope experiments have been performed on herbivores, so in this study I analyzed the carbon and nitrogen stable isotope ratios in the diet and feces of the meerkat (Suricata suricatta), a small omnivorous mammal. The carbon trophic discrimination factor between diet and feces (Δ13Cfeces) is calculated to be 0.1 ± 1.5‰, which is not significantly different from zero, and in turn, not different than the dietary input. On the other hand, the nitrogen trophic discrimination factor (Δ15Nfeces) is 1.5 ± 1.1‰, which is significantly different from zero, meaning it is different than the average dietary input. Based on data generated in this experiment and a review of the published literature, carbon isotopes of feces characterize diet, while nitrogen isotope ratios of feces are consistently higher than dietary inputs, meaning a discrimination factor needs to be taken into account. The carbon and nitrogen stable isotope values of feces are an excellent snapshot of diet that can be used in concert with other analytical methods to better understand ecology, diets, and habitat use of mammals.
Acacia wollarensis (Fabaceae, Mimosoideae sect. Botrycephalae), a distinctive new species endemic to the Hunter Valley of New South Wales, Australia
Authors: Bell Stephen , Driscoll Colin 
Published: June 2017

Acacia wollarensis (Fabaceae, Mimosoideae sect. Botrycephalae), a new and restricted species from the upper Hunter Valley of New South Wales, is described and illustrated. The new taxon has affinities to Acacia fulva and the rare A. chrysotricha, but differs from these most prominently in the densely white-setose rachis and pinnules. At present, the new taxon is known only from two populations and under IUCN guidelines qualifies
as vulnerable, but is not under immediate threat.
Robust adaptive output‐feedback control for a class of nonlinear systems with hysteresis compensation controller
Authors: Zhang Xiuyu , Li Zhi , Su Chun‐Yi , Lin Yan 
Published: June 2017

SummaryIn this paper, a robust adaptive output‐feedback dynamic surface control scheme is proposed for a class of single‐input single‐output nonlinear systems preceded by unknown hysteresis with the following features: (1) a hysteresis compensator is designed in the control signal to compensate the hysteresis nonlinearities with only the availability of the output of the control system; (2) by estimating the norm of the unknown parameter vector and the maximum value of the hysteresis density function, the number of the estimated parameters is reduced, which implies that the computational burden is greatly reduced; (3) by introducing the initializing technique, the initial conditions of the state observer and adaptive laws of unknown parameters can be properly chosen, and the arbitrarily small
norm of the tracking error is achieved. It is proved that all the signals in the closed‐loop system are ultimately uniformly bounded and can be arbitrarily small. Simulation results show the validity of the proposed scheme.
Observer‐based nonlinear feedback decentralized neural adaptive dynamic surface control for large‐scale nonlinear systems
Authors: Gao Shigen , Dong Hairong , Ning Bin 
Published: June 2017

SummaryThis paper presents a nonlinear gain feedback technique for observer‐based decentralized neural adaptive dynamic surface control of a class of large‐scale nonlinear systems with immeasurable states and uncertain interconnections among subsystems. Neural networks are used in the observer design to estimate the immeasurable states and thus facilitate the control design. Besides avoiding the complexity problem in traditional backstepping, the new nonlinear feedback gain method endows an automatic regulation ability into the pioneering dynamic surface control design and improvement in dynamic performance. Novel Lyapunov function is designed and rigorous stability analysis is given to show that all the closed‐loop signals are kept semiglobally uniformly ultimately bounded, and the output tracking errors can be guaranteed to converge to sufficient area around zero, with the bound values characterized by design parameters in an explicit manner. Simulation and comparative results are shown to verify effectiveness.

Published: June 2017

AbstractAn approach has been developed for the practical synthesis of two different, structurally robust, pseudoenantiomeric amino Tf‐amido organocatalysts with acis‐1,2‐cyclohexanediamine structure. These pseudoenantiomeric organocatalysts, which are very useful for the practical synthesis of both enantiomeric aldol products, are easily prepared from commercially availablecis‐4‐cyclohexene‐1,2‐dicarboxylic acid in a four‐step sequence. The Diels–Alder strategy of 2‐alkyl‐1,3‐butadiene and maleic anhydride would provide a general approach to the facile synthesis of various pseudoenantiomeric organocatalysts.
N‐Terminally Truncated Amyloid‐β(11–40/42) Cofibrillizes with its Full‐Length Counterpart: Implications for Alzheimer's Disease

Published: June 2017

AbstractAmyloid‐β peptide (Aβ) isoforms of different lengths and aggregation propensities coexist in vivo. These different isoforms are able to nucleate or frustrate the assembly of each other. N‐terminally truncated Aβ(11–40) and Aβ(11–42) make up one fifth of plaque load yet nothing is known about their interaction with full‐length Aβ(1–40/42). We show that in contrast to C‐terminally truncated isoforms, which do not co‐fibrillize, deletions of ten residues from the N terminus of Aβ have little impact on its ability to co‐fibrillize with the full‐length counterpart. As a consequence, N‐terminally truncated Aβ will accelerate fiber formation and co‐assemble into short rod‐shaped fibers with its full‐length Aβ counterpart. This has implications for the assembly kinetics, morphology, and toxicity of all Aβ isoforms.

Published: June 2017

One‐pot and three components C‐S bond formation reactions in thioethers and S‐aryl‐carbamodithioates have been catalyzed by a copper heterogeneous nano‐catalyst supported on modified AlPO4 under different reaction conditions. The above‐mentioned nano‐catalyst has been characterized by various techniques such as SEM, TEM, AFM, XRD, FT‐IR, UV–Vis, CV, BET, TGA, ICP and XPS spectrometry and its particle size was estimated to be between 60–110 nm. Finally, the reusability of the catalyst up to ten cycles without any significant leaching is one of the outstanding properties of the catalyst.

Published: June 2017

ABSTRACTThe synthesis of bromo derivatives cardanolic novolac resins (BCNR) using infrared, thermogravimetric analysis, differential scanning calorimetry, gel permeation chromatography, nuclear magnetic resonance 1H and 13C methods was studied. The mechanism of thermal degradation of BCNR is proposed. It is shown, that particleboards manufactured using PU‐(BCNR) as an adhesive are materials with enhanced flame retardant properties, meeting the requirements of P7 class to EN 312 (especially durable moisture‐resistant particleboards) and the requirements of the emission class Super E0. The bromine in the structure of the cardanol‐containing polyurethane binder allows achieving both high physical and mechanical characteristics of the particleboards and resistance to flame. © 2017 Wiley Periodicals, Inc.
