Accuracy of liquid‐based cytology
Authors: Confortini Massimo , Bergeron Christine , Desai Mina , Negri Giovanni , Palma Paolo Dalla , Montanari Gioia , Pellegrini Antonella , Ronco Guglielmo 
Published: June 2010

AbstractBACKGROUND:In the New Technologies for Cervical Cancer Screening (NTCC) randomized controlled trial, no significant increase in the sensitivity of liquid‐based cytology (LBC) was observed compared with conventional cytology. Both were interpreted by cytologists who had limited previous LBC experience. The objective of the current study was to assess whether different results could be expected with experienced LBC interpreters.METHODS:A stratified, random sample of 818 LBC slides from the NTCC study was obtained. These slides were reviewed blindly and independently by 3 international experts who did not participate in the NTCC. The sensitivity and specificity of external experts were estimated for cervical intraepithelial neoplasia grade 2 or greater (CIN2+) and for CIN3+ histology, and the differences were compared with the sensitivity and specificity of the original cytologic interpretation using cutoffs of atypical squamous cells of undetermined significance (ASCUS) and low‐grade squamous intraepithelial lesion (LSIL).RESULTS:With the endpoint of CIN2+ histology, the difference in sensitivity between external experts and the original interpretation was −5.3 (95% confidence interval [CI], −16.0 to 5.4) with ASCUS as the cutoff and 3.8 (95% CI, −8.2 to 15.8) with LSIL as the cutoff. External experts had slightly lower specificity using ASCUS as the cutoff (−3.4; 95% CI, −3.9 to −2.9) and LSIL as the cutoff (−0.7; 95% CI, −1.0 to −0.4).CONCLUSIONS:The accuracy of the external experts' interpretation was similar to that of the original interpretation. Therefore, the current results indicated that LBC is not expected to increase sensitivity even if it is used by interpreters who have extensive experience with this technique.

A computationally efficient method for assessing muscle function during human locomotion
Authors: Lin Yi‐Chung , Kim Hyung Joo , Pandy Marcus G. 
Published: June 2010

AbstractWhen a muscle is activated, it contracts, develops force, and, by virtue of a lever arm, exerts a torque about one or more of the joints it spans. Dynamic coupling in a multi‐joint system ensures that a muscle can simultaneously accelerate all the joints in the body, even those it does not span. The overall goal of the present study was to develop an accurate and computationally efficient method for quantifying muscle function during human locomotion. Our specific aims were first to assess the accuracy of the method by comparing its results against reference data reported in the literature; and second to demonstrate the application of the method in the study of leg‐muscle function in walking and running. The method is based on using a pseudo‐inverse to decompose the ground reaction force, enabling each muscle's contribution to the acceleration of any point on the body to be found at each instant of the gait cycle. One of the most appealing features of the pseudo‐inverse method is that it can be applied either to data generated from a computer simulation or to measurements obtained from a gait experiment. The pseudo‐inverse method is also roughly three orders of magnitude faster than an alternative approach based on perturbation analysis, which is commonly used to assess muscle function in human gait. The results show that the pseudo‐inverse method is able to accurately reproduce reference data reported for normal walking. Predictions of leg‐muscle function in walking and running are also consistent with findings reported previously by others. Copyright © 2010 John Wiley & Sons, Ltd.
Universal biquad filter topology using low‐voltage current mirrors
Authors: Laoudias Costas , Psychalinos Costas 
Published: June 2010

SUMMARYA single input multiple output biquad filter topology realized using current mirrors as active elements is introduced in this manuscript. The proposed topology simultaneously realizes all the standard transfer functions of a biquad filter without modifying its structure. Some attractive characteristics offered by the proposed topology are the employment of only grounded capacitors as passive elements, the electronic adjustment of the resonant frequency, and the capability for operation under a low‐voltage environment. The operation of the proposed topology has been validated through simulation results, where the most important performance factors have been evaluated in the case of a bandpass filter transfer function.

Relationship of glucose regulation to changes in weight: a systematic review and guide to future research
Authors: Chiu Ching‐Ju , Wray Linda A. , Beverly Elizabeth A. 
Published: June 2010

AbstractAlthough weight gain and obesity are risk factors for poor glucose regulation, the relationship, if any, of glucose regulation to changes in weight is not well understood. The purpose of this study was to conduct a systematic review of research examining the relationship of glucose regulation to changes in weight in human‐based studies and to provide guidelines for future research in this area. We searched electronic databases and reference sections of relevant articles, including both diabetic and non‐diabetic populations, to locate all the literature published before February 2010, and then conducted a systematic review across studies to compare the research designs and findings. The 22 studies meeting our criteria for review generally supported the relationship of glucose regulation to changes in weight. Three studies reported that poor glucose regulation is associated with weight gain; 12 studies concluded that poor glucose regulation is associated with weight loss; 5 showed complex relationships depending on age, sex, or race/ethnicity; and 2 suggested no relationship. The diverse findings may imply that the direction (negative or positive) of the relationship may depend on specific conditions. More research focused on different subpopulations may provide more definitive information supplemental to the current preliminary findings. Recommendations regarding future research in this particular area are provided in the discussion. Copyright © 2010 John Wiley & Sons, Ltd.
Preferential flows and travel time distributions: defining adequate hypothesis tests for hydrological process models
Authors: Beven Keith J. 
Published: June 2010

AbstractThis introduction to the second annual review issue of Hydrological Processes tries to put the collection of papers on preferential flows and travel time distributions into a more general context of testing models as hypotheses about how catchment systems function. It is suggested that, because of the possibilities of non‐stationary and epistemic errors in both data and models, such tests could be carried out within a rejectionist limits‐of‐acceptability framework. The principles and difficulties of hypothesis testing within these particular research areas are discussed. An important point to take from this discussion is that the use of a formal testing framework, and the consequent rejection of models as hypotheses after allowing for uncertainties in the data, is the starting point for developing better theories and data sets.

A methodology for ecosystem-scale modeling of selenium
Authors: Presser Theresa S , Luoma Samuel N 
Published: June 2010

Abstract
The main route of exposure for selenium (Se) is dietary, yet regulations lack biologically based protocols for evaluations of risk. We propose here an ecosystem-scale model that conceptualizes and quantifies the variables that determine how Se is processed from water through diet to predators. This approach uses biogeochemical and physiological factors from laboratory and field studies and considers loading, speciation, transformation to particulate material, bioavailability, bioaccumulation in invertebrates, and trophic transfer to predators. Validation of the model is through data sets from 29 historic and recent field case studies of Se-exposed sites. The model links Se concentrations across media (water, particulate, tissue of different food web species). It can be used to forecast toxicity under different management or regulatory proposals or as a methodology for translating a fish-tissue (or other predator tissue) Se concentration guideline to a dissolved Se concentration. The model illustrates some critical aspects of implementing a tissue criterion: 1) the choice of fish species determines the food web through which Se should be modeled, 2) the choice of food web is critical because the particulate material to prey kinetics of bioaccumulation differs widely among invertebrates, 3) the characterization of the type and phase of particulate material is important to quantifying Se exposure to prey through the base of the food web, and 4) the metric describing partitioning between particulate material and dissolved Se concentrations allows determination of a site-specific dissolved Se concentration that would be responsible for that fish body burden in the specific environment. The linked approach illustrates that environmentally safe dissolved Se concentrations will differ among ecosystems depending on the ecological pathways and biogeochemical conditions in that system. Uncertainties and model sensitivities can be directly illustrated by varying exposure scenarios based on site-specific knowledge. The model can also be used to facilitate site-specific regulation and to present generic comparisons to illustrate limitations imposed by ecosystem setting and inhabitants. Used optimally, the model provides a tool for framing a site-specific ecological problem or occurrence of Se exposure, quantify exposure within that ecosystem, and narrow uncertainties about how to protect it by understanding the specifics of the underlying system ecology, biogeochemistry, and hydrology.

Estimating sediment quality thresholds to prevent restrictions on fish consumption: Application to polychlorinated biphenyls and dioxins–furans in the Canadian Great Lakes

Abstract
Sediment quality thresholds (SQTs) are used by a variety of agencies to assess the potential for adverse impact of sediment-associated contaminants on aquatic biota, typically benthic invertebrates. However, sedimentary contaminants can also result in elevated fish contaminant levels, triggering consumption advisories that are protective of humans. As such, SQTs that would result in fish concentrations below consumption advisory levels should also be considered. To illustrate how this can be addressed, we first calculate biota sediment accumulation factors (BSAFs) for polychlorinated biphenyls (total PCB) and polychlorinated dioxins–furans (PCDD/Fs) in the Canadian Great Lakes using measured lake sediment and fish tissue concentrations in 4 fish species, namely, lake trout, whitefish, rainbow trout, and channel catfish. Using these BSAFs and tissue residue values for fish consumption advisories employed by the Ontario Ministry of the Environment (OMOE, Canada), we derive fish consumption advisory-based SQTs (fca-SQTs) that are likely to result in fish tissue residues that are safe to eat without restriction. The PCDD/Fs fca-SQTs ranged from 6 to 128 pg toxic equivalents (TEQ)/g dry weight (dw) and were above the Canadian Council of the Ministers of the Environment (CCME) threshold effect level (TEL) of 0.85 pg TEQ/g dw. In contrast, the total PCB fca-SQTs ranged from 1 to 60 ng/g dw and were generally below the CCME's TEL of 34.1 ng/g and OMOE's lowest effect level (LEL) of 70 ng/g; however, they were consistent with the OMOE's no effect level (NEL) of 10 ng/g. The fca-SQTs derived using the BSAF as well as food chain multiplier (FCM) approach for a smaller scale system (Hamilton Harbour in Lake Ontario) corresponded well with average lakewide Lake Ontario fca-SQTs. This analysis provides approximate sediment concentrations necessary for reducing fish consumption advisories for each of the Canadian Great Lakes and emphasizes the impacts of historical lake sediment contamination on fish advisories. We believe that this approach merits consideration in sediment guideline development. Integr Environ Assess Manag 2010;6:641–652. © 2010 SETAC
FGFs in endochondral skeletal development
Authors: Degnin Catherine R. , Laederich Melanie B. , Horton William A. 
Published: June 2010

AbstractThe mammalian skeleton developments and grows through two complementary pathways: membranous ossification, which gives rise to the calvarial bones and distal clavicle, and endochondral ossification, which is responsible for the bones of the limbs, girdles, vertebrae, face and base of the skull and the medial clavicle. Fibroblast growth factors (FGFs) and their cognate FGF receptors (FGFRs) play important roles in regulating both pathways. However, the details of how FGF signals are initiated, propagated and modulated within the developing skeleton are only slowly emerging. This prospect will focus on the current understanding of these events during endochondral skeletal development with special attention given to concepts that have emerged in the past few years. J.

Oxidative stress‐induced attenuation of thrombospondin‐1 expression in primary rat astrocytes
Authors: Chen Jen‐Kun , Zhan Yan‐Jie , Yang Chung‐Shi , Tzeng Shun‐Fen 
Published: June 2010

AbstractAstrocytes, the major glial population in the central nervous system (CNS), can secrete thrombospondin (TSP)‐1 that plays the role in synaptogenesis and axonal sprouting during CNS development and tissue repair. However, little is known about the regulation of TSP‐1 expression in astrocytes under oxidative stress condition. Here, a hypoxic mimetic reagent, cobalt chloride (CoCl2), was used to initiate hypoxia‐induced oxidative stress in primary rat astrocytes. CoCl2 at the concentration range of 0.1–0.5 mM was found to cause no significant cell death in primary rat astrocytes. However, CoCl2 at 0.2–0.5 mM increased intracellular reactive oxygen species (ROS) levels and glyceraldehyde 3‐phosphate dehydrogenase (GAPDH) gene expression that is known as a hallmark for oxidative damage. We further found that TSP‐1 mRNA expression in astrocytes was inhibited dose‐ and time‐dependently by CoCl2. TSP‐1 mRNA levels were increased in CoCl2‐exposed astrocytes in the presence of the inhibitors (U0126 and PD98059) of mitogen‐activated protein kinase/extracellular signal‐regulated kinases (MAPK/ERK), when compared to that detected in the culture only exposed to CoCl2. Moreover, the inhibition in TSP‐1 mRNA expression by CoCl2 was blocked by the addition of the potent antioxidant, N‐acetylcysteine (NAC). Thus, we conclude that CoCl2 inhibits TSP‐1 mRNA expression in astrocytes via a ROS mechanism possibly involving MAPK/ERK. This inhibition may occur after CNS injury and impair the supportive function of astrocytes on neurite growth in the injured CNS tissues. J. Cell. Biochem. 112: 59–70, 2011. © 2010 Wiley‐Liss, Inc.
