The role of banned substance residue analysis in the control of dietary supplement contamination
Authors: Judkins Catherine MG , Teale Philip , Hall David J 
Published: September 2010

AbstractThe potential for contaminated dietary supplements to result in a failed doping test remains a concern for athletes, trainers, and sporting authorities despite improvements to regulatory guidelines. Previous surveys of readily available supplements confirm that many are contaminated with steroids and stimulants prohibited for use in elite sport. Suggested responses to this issue include the complete avoidance of all supplements. Many athletes, however, use nutritional supplements to achieve effective training and also to ensure that daily nutritional requirements are met (e.g. recommended levels of vitamins and minerals). This ensures that the use of supplements is and will remain the norm for a range of sports. As a result, an alternative approach of rigorous testing of materials destined for use by elite athletes has been introduced in several countries. While the testing of final product for banned substances may help mitigate the problem, it will not help to remove the underlying issue of contamination. In this article we describe an alternative approach that uses appropriate quality assurance procedures backed up by testing to remove sources of contamination. The decrease in the incidence of contamination amongst supplement companies adopting such a system is explained, and contrasted with the relatively high incidences of contamination found in products that are not part of a quality system. These findings are of key importance to both supplement manufacturers and those involved in advising athletes about supplement use. Copyright © 2010 John Wiley & Sons, Ltd.

Influence of water flux and redox conditions on chlorobenzene concentrations in a contaminated streambed
Authors: Schmidt Christian , Martienssen Marion , Kalbus Edda 
Published: September 2010

AbstractSignificant natural attenuation may occur on the passage of groundwater plumes through streambed sediments because of the transition from anaerobic to aerobic conditions and an increased microbial activity. Varying directions and magnitudes of water flow in the streambed may enhance or inhibit the supply of oxygen to the streambed and thus influence the redox zoning. In a field study at a small stream in the industrial area of Bitterfeld‐Wolfen, we observed the variability of hydraulic gradients, streambed temperatures, redox conditions and monochlorobenzene (MCB) concentrations in the streambed over the course of 5 months. During the observation period, the hydrologic conditions changed from losing to gaining. Accordingly, the temperature‐derived water fluxes changed from recharge to discharge. Redox conditions were highly variable between − 170 and 368 mV in the shallow streambed at a depth of 0·1 m below the streambed surface. Deeper in the streambed, at depths of 0·3 m and 0·5 m, the redox conditions were more stable between − 198 and − 81 mV and comparable to those typically found in the aquifer. MCB concentrations in the streambed at 0·3 and 0·5 m depth increased with increasing upward water flux. The MCB concentrations in the shallow streambed at 0·1 m depth appeared to be independent of the hydrologic conditions suggesting that degradation of MCB may have occured.

AbstractBackground and ObjectivesBiopsy of Cloquet's node (CN) during groin dissection has been used to indicate need for pelvic dissection. With earlier detection of microscopic regional disease in the era of sentinel node biopsy (SNB), frequency of positive CN may be so low that routine biopsy is unwarranted.MethodsPatients with positive groin SNB from 2000 to 2008 were identified from two centers. Cases where CN was identified at completion node dissection were selected. Lymphoscintigraphic, surgical, pathologic, and recurrence data were reviewed.ResultsCN was identified in 53 cases. Median age was 44.5 years (range 7–77); median Breslow depth, 1.98 mm (range 0.5–25.0); % Clark's level IV/V, 90%; and % ulceration, 41.5%. Fifty (94.3%) underwent groin dissection alone; three others underwent concomitant pelvic dissection. Two (3.8%) patients had positive CN; both had additional indications for pelvic dissection. Delayed pelvic recurrence rate was 2/53 (3.8%); both patients had negative CN. In the three patients treated with concurrent groin and pelvic dissection, CN reflected pelvic nodal status in two cases; the third had pelvic metastases despite negative CN.ConclusionsAfter positive SNB, disease involvement of CN is rare. Patients with positive biopsies of CN in the SNB era appear likely to have additional indications for pelvic dissection, minimizing utility of CN biopsy. Routine intraoperative sampling of CN may not be warranted during groin dissection for positive SNB. J. Surg. Oncol. 2010;102:315–320. © 2010 Wiley‐Liss, Inc.
A quick diagnostic test for NMR receiver gain compression
Authors: Mo Huaping , Harwood John S. , Raftery Daniel 
Published: September 2010

AbstractModern NMR spectrometers require receivers to work within their linear ranges to maintain high fidelity line shape and peak integration. For better sensitivity, the receiver gain has to be optimized to detect dilute analytes; however, gain compression needs to be avoided. Here, we explore if and how linear receiver performance can be achieved for a couple of representative gain settings on a spectrometer. In the case of slight receiver gain compression, not only will the peak integral be attenuated but a very small line‐shape change can also be observed. Hence, we can resort to resonance integration and line‐shape analysis for gain compression diagnosis. As such, NMR signals, regardless of their observed amplitude difference in frequency domain, can be accurately compared in quantitative analysis. Copyright © 2010 John Wiley & Sons, Ltd.

AbstractBACKGROUNDWe examined whether human epidermal growth factor‐2(HER‐2) overexpression could be a useful marker of outcome after hormone therapy in patients with M1b prostate cancer (PC).SUBJECTS AND METHODSThe subjects were 102 patients who were diagnosed with M1b PC at Aichi Medical University Hospital. HER‐2 expression was determined by immunohistochemical (IHC) staining using initial needle biopsy specimens for diagnosis. The results were classified into four grades (0, 1+, 2+, 3+), and scores of 1+ or greater were considered overexpression and defined as positive.RESULTSThe results showed a rating of 0 in 72 subjects, 1+ in 10, 2+ in 14, and 3+ in 6; 30 subjects (29.4%) were classified as HER‐2 positive. Comparison of clinical data of HER‐2 positive and negative subjects obtained at baseline revealed many of the subjects with high‐grade tumors by Gleason score were HER‐2 positive (P = 0.030). The prostate‐specific antigen (PSA) relapse was observed in 76 subjects and cause‐specific death occurred in 44. A significant difference was observed only in the item HER‐2 (negative vs. positive) by multivariate Cox proportional hazard analysis. The 5‐year PSA relapse‐free rate was 0% in subjects with HER‐2 positive (26/30), and 43.9% in subjects with HER‐2 negative (50/72, P = 0.0192). The 5‐year cause‐specific survival rate was 40.9% in subjects with HER‐2 positive (30/102), and 67.3% in subjects with HER‐2 negative (72/102, P = 0.0301).CONCLUSIONHER‐2 overexpression as determined by IHC staining using needle biopsy specimens for diagnosis with M1b PC is a significant prognostic factor for PSA relapse after hormone therapy and unfavorable outcome.

Magnetic characterization of Bi2FeMnO6 film grown on (100) SrTiO3 substrate
Authors: Zhao Hongyang , Kimura Hideo , Cheng Zhenxiang , Wang Xiaolin , Ozawa Kiyoshi , Nishida Takashi 
Published: September 2010

AbstractSingle phase Bi2FeMnO6 films on (100) SrTiO3 substrate were fabricated using a pulsed laser deposition method through optimization of the preparation conditions. The magnetic moment is 0.30μB at 5 K in the magnetic field of 1 T, indicating that B site cations of Fe and Mn are disordered in the sample. The zero‐field‐cooling (ZFC) and field‐cooling (FC) magnetization curves measured from 2 K to 400 K coincide at 360 K. This is consistent with the observation that hysteresis disappears at 360 K, revealing the antiferromagnetic transition at this temperature. A spin‐glass‐like behaviour was observed at low temperature (∼100 K) with a cusp of 25 K. Mn shows multiple valence states in the film. It is possibly because Mn2+ and Mn4+ could decrease the Jahn–Teller effect from Mn3+ in the film which results in less lattice distortion. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Biomimetic Synthesis of Gelatin Polypeptide-Assisted Noble-Metal Nanoparticles and Their Interaction Study
Authors: Liu Ying , Liu Xiaoheng , Wang Xin 
Published: September 2010

AbstractHerein, the generation of gold, silver, and silver–gold (Ag–Au) bimetallic nanoparticles was carried out in collagen (gelatin) solution. It first showed that the major ingredient in gelatin polypeptide, glutamic acid, acted as reducing agent to biomimetically synthesize noble metal nanoparticles at 80°C. The size of nanoparticles can be controlled not only by the mass ratio of gelatin to gold ion but also by pH of gelatin solution. Interaction between noble-metal nanoparticles and polypeptide has been investigated by TEM, UV–visible, fluorescence spectroscopy, and HNMR. This study testified that the degradation of gelatin protein could not alter the morphology of nanoparticles, but it made nanoparticles aggregated clusters array (opposing three-dimensional α-helix folding structure) into isolated nanoparticles stabilized by gelatin residues. This is a promising merit of gelatin to apply in the synthesis of nanoparticles. Therefore, gelatin protein is an excellent template for biomimetic synthesis of noble metal/bimetallic nanoparticle growth to form nanometer-sized device.
Influence of dietary modifications on the blood pressure response to antihypertensive medication

Published: September 2010

Identifying dietary modifications that potentiate the blood pressure (BP)-lowering effects of antihypertensive medications and that are practical for free-living people may assist in achieving BP reduction goals. We assessed whether two dietary patterns were effective in lowering BP in persons on antihypertensive therapy and in those not on therapy. Ninety-four participants (38/56 females/males), aged 55·6 (sd 9·9) years, consumed two 4-week dietary regimens in random order (Dietary Approaches to Stop Hypertension (DASH)-type diet and low-Na high-K (LNAHK) diet) with a control diet before each phase. Seated home BP was measured daily for the last 2 weeks in each phase. Participants were grouped based on antihypertensive drug therapy. The LNAHK diet produced a greater fall in systolic BP (SBP) in those on antihypertensive therapy ( − 6·2 (sd 6·0) mmHg) than in those not on antihypertensive therapy ( − 2·8 (sd 4·0) mmHg) (P = 0·036), and this was greatest for those on renin–angiotensin system (RAS) blocker therapy ( − 9·5 (sd 6·4) mmHg) (interaction P = 0·007). The fall in SBP on the DASH-type diet, in those on therapy (overall − 1·1 (sd 6·2) mmHg; renin–angiotensin blocker therapy − 4·2 (sd 4·7) mmHg), was not as marked as that observed on the LNAHK diet. Dietary modifications are an important part of all hypertension management regimens, and a low-Na and high-K diet enhances the BP-lowering effect of antihypertensive medications, particularly those targeting the RAS.

Published: September 2010

Home ranges of seven Guiana dolphins (Sotalia guianensis) (Van Bénéden, 1864) were studied in the Cananéia estuary (~25°03′S 47°55′W), south-eastern Brazil. Boat-based observations were conducted from May 2000 to July 2003 in ~132 km2 of protected inner waters. The photo-identification technique was used to follow naturally marked individuals through time and space. From a total of 138 catalogued individuals, five males and two females presented 20+ sightings and were used for home range estimation. Sightings were plotted and analysed in a Geographic Information System (GIS). With the ‘Home Range Tools’ extension the fixed kernel density estimator with band width (smoothing parameter) chosen via least squares cross-validation was performed for each individual. The fixed kernel method was used to estimate the non-parametric utility distribution of each dolphin, keeping band width (h) constant for a data set. The first polygons created by these parameters had an amoeboid shape and in some cases more than one centre of activity. The 95% home range estimated outlines varied from 1.6 to 22.9 km2 (7.9 ± 8.3 km2). This large interval shows strong evidences on individual variation in S. guianensis' home ranges. Several individuals showed small home ranges when compared to other cetacean species. An overlap of home ranges of different sizes and shapes were observed for Guiana dolphins with large range movements. Centres of activity were concentrated in the main entrance of the Cananéia estuary. This was a first attempt to understand the way S. guianensis uses the Cananéia estuary and such data are essential for conservation and management purposes.
Structure of novel exocrine glands in Calanus species with notes on their possible function
Authors: Nishida Shuhei , Nonomura Takumi 
Published: September 2010

The structure of hitherto-unknown exocrine glands in the caudal rami of the pelagic copepods of the genus Calanus was investigated, together with the vertical, diel and seasonal variations in the occurrence of granules secreted from the glands. Zooplankton samples were collected in Sagami Bay by vertical tows of a net from 4 discrete layers at 250-m intervals in the upper 1000 m both day and night, with an additional seasonal sampling in the upper 200 m. The samples contained copepodids of Calanus sinicus (stages IV–VI), C. jashnovi (stages IV–V), and unidentified Calanus (stages I–III), which possessed the glands regardless of the developmental stage and sex. Each caudal ramus has an inner- and an outer gland each of which opens in a pore at the ventral base of a caudal seta. According to light microscopy the cavities of only the inner glands contained many transparent granules, some of which appeared to have been discharged to the environment. The granules were present regardless of day/night, depth, and season, with the maximum number of 52/copepod. The cells surrounding the inner cavity contained well-developed rough endoplasmic reticulum, mitochondria, Golgi-bodies, and secretory granules; the outer cavity contained granules of much lower density than those in the inner cavity. These observations rule out the possible functions of the glands for egg and sex pheromone production, and suggest most likely function is predator avoidance. However, neither has mechanical disturbance excited luminescence, nor has ultraviolet emission excited fluorescence, suggesting the secretion is non-luminescent. Alternative possible functions include secretion of defensive substances or substances that might enhance swarm formation. A survey of preserved copepod collections indicated presence of similar glands in Calanus helgolandicus, C. pacificus, Cosmocalanus darwinii, Mesocalanus tenuicornis, and Nannocalanus minor, suggesting evolution of the glands in the common ancestor of these species that comprise a monophyletic group within the Calanidae.
Factors Influencing AAC Usage by Individuals With Aphasia
Authors: Purdy Mary , Dietz Aimee 
Published: September 2010

Abstract
Instructing individuals with aphasia in the usage of AAC strategies and devices is a challenging endeavor. Not only does this population present with a wide range of linguistic impairments, but many individuals also demonstrate cognitive deficits, which may adversely affect communication. This paper will summarize the wide variety of cognitive deficits demonstrated by individuals with aphasia, specifically attention, memory and executive functioning problems. In addition, we will review the impact of these cognitive impairments on communicative competence. Finally, we will discuss an intervention, the Multimodality Communication Training Program (MCTP), designed to address the cognitive impairments that influence AAC intervention.
