Reflex UroVysion testing in suspicious urine cytology cases
Authors: Ferra Susana , Denley Ryan , Herr Harry , Dalbagni Guido , Jhanwar Suresh , Lin Oscar 
Published: January 2009

AbstractBACKGROUND:UroVysion is a US Food and Drug Administration–approved fluorescence in situ hybridization (FISH) probe set for use in the detection of recurrent urothelial carcinoma and in patients with hematuria. The objective of the current study was to evaluate the usefulness of UroVysion as a reflex test in patients with a suspicious urine cytology diagnosis. The rationale was that a more aggressive workup might be indicated in patients with a suspicious cytology diagnosis and positive UroVysion test.METHODS:The study population included 161 urine specimens diagnosed as suspicious over a period of 12 months. The sensitivity, specificity, negative predictive value (NPV), and positive predictive value (NPV) were calculated based on the histologic and cystoscopic correlation.RESULTS:The results using the reporting criteria suggested by the manufacturer demonstrated a sensitivity of 68.3%, a specificity of 39.7%, a PPV of 56.8%, and a NPV of 51.9%. The results using the presence of any cytogenetic abnormality as a positive FISH test demonstrated a sensitivity of 82.9%, a specificity of 21.7%, a PPV of 54.8%, and an NPV of 51.7%.CONCLUSIONS:A negative UroVysion test did not rule out the presence of low‐grade or high‐grade urothelial carcinoma in urine specimens diagnosed as suspicious. The use of less strict criteria dramatically increased the sensitivity of UroVysion FISH; however, there was a marked decrease in specificity noted. The results in this current study appear to indicate that a more aggressive workup of patients with a suspicious cytology, positive UroVysion result, and negative cystoscopic evaluation is not currently justified.

Cloning and immunoreactivity of the 5‐HT1Mac and 5‐HT2Mac receptors in the central nervous system of the freshwater prawn Macrobrachium rosenbergii

Published: January 2009

AbstractBiogenic amines are implicated in several mental disorders, many of which involve social interactions. Simple model systems, such as crustaceans, are often more amenable than vertebrates for studying mechanisms underlying behaviors. Although various cellular responses of biogenic amines have been characterized in crustaceans, the mechanisms linking these molecules to behavior remain largely unknown. Observed effects of serotonin receptor agonists and antagonists in abdomen posture, escape responses, and fighting have led to the suggestion that biogenic amine receptors may play a role in modulating interactive behaviors. As a first step in understanding this potential role of such receptors, we have cloned and fully sequenced two serotonin receptors, 5‐HT1Mac and 5‐HT2Mac, from the CNS of the freshwater prawn Macrobrachium rosenbergii and have mapped their CNS immunohistochemical distribution. 5‐HT1Mac was found primarily on the membranes of subsets of cells in all CNS ganglia, in fibers that traverse all CNS regions, and in the cytoplasm of a small number of cells in the brain and circum‐ and subesophageal ganglia (SEG), most of which also appear to contain dopamine. The pattern of 5‐HT2Mac immunoreactivity was found to differ significantly; it was found mostly in the central neuropil area of all ganglia, in glomeruli of the brain's olfactory lobes, and in the cytoplasm of a small number of neurons in the SEG, thoracic, and some abdominal ganglia. The observed differences in terms of localization, distribution within cells, and intensity of immunoreactive staining throughout the prawn's CNS suggest that these receptors are likely to play different roles.

Non‐structure‐specific intensity measure parameters and characteristic period of near‐fault ground motions
Authors: Yang Dixiong , Pan Jianwei , Li Gang 
Published: January 2009

AbstractThis paper focuses on the effects of long‐period pulse of near‐fault ground motions on the structural damage potential. Two sets of near‐fault ground motion records from Chi‐Chi, Taiwan earthquake and Northridge earthquake with and without distinct pulse are selected as the input, and the correlation analysis between 30 non‐structure‐specific intensity measure parameters and maximum inelastic displacements and energy responses (input energy and hysteretic energy) of bilinear single degree of freedom systems are conducted. Based on the frequency characteristic of near‐fault ground motions with remarkable long‐period components, two intensity indices are proposed, namely, the improved effective peak acceleration (IEPA) and improved effective peak velocity (IEPV). In addition a new characteristic period of these ground motions is defined based on IEPA and IEPV. Numerical results illustrate that the intensity measure parameters related to ground acceleration present the best correlation with the seismic responses for rigid systems; the velocity‐related and displacement‐related parameters are better for medium‐frequency systems and flexible systems, respectively. The correlation curves of near‐fault ground motions with velocity pulse differ from those of ground motions without pulse. Moreover, the improved parameters IEPA and IEPV of near‐fault impulsive ground motions enhance the performance of intensity measure of corresponding conventional parameters, i.e. EPA and EPV. The new characteristic period based on IEPA and IEPV can better reflect the frequency content of near‐fault ground motions. Copyright © 2009 John Wiley & Sons, Ltd.
Working with youth on LGBT issues: why Gay–Straight Alliance advisors become involved
Authors: Valenti Maria , Campbell Rebecca 
Published: January 2009

AbstractThis phenomenological qualitative study explores motivation for citizen participation in a local context by exploring the experiences of Gay‐Straight Alliance (GSA) club advisors from public high schools. Fourteen advisors from one midwestern state were randomly recruited for participation. Inductive and deductive qualitative analyses elucidated themes and subthemes surrounding the motivation for becoming an advisor. Two major themes that emerged were a protective attitude toward lesbian, gay, bisexual, and transgender (LGBT) youth, a personal connection with sexual minority people/issues. It became clear that deciding to become a GSA advisor was not necessarily an easy decision. Therefore, the decision‐making process was analyzed, elucidating themes surrounding worries (possible lack of credibility, fear of job loss, and being accused of recruiting youth to the ‘gay lifestyle’) and security (tenure or protections against being fired, and being married). Limitations and implications for future research and practice are discussed. © 2009 Wiley Periodicals, Inc.

AbstractPurpose.To determine the safety and efficacy of real‐time, sonographic‐guided, random percutaneous needle biopsy of the liver in a tertiary medical center.Method.From an IRB‐approved biopsy database, all patients who had random liver biopsy performed over a 24‐month period were selected. In 350 patients, 539 random percutaneous needle biopsies of the liver were performed under real‐time sonographic visualization. The following were recorded from the electronic medical record: patient demographics, indication for biopsy procedure; radiologist's name; needle type and gauge and number of passes; use and amount of IV sedation or anesthesia; adequacy of the specimen; and complications following the procedure.Result.Of 539 biopsies, 378 (70%) biopsy procedures were performed on liver transplant recipients. Of the biopsy procedures in nontransplant patients, 81/161 (50%) concurrently underwent biopsy of a focal liver mass. An 18‐gauge automated core biopsy needle was used in 536/539 (99%). Median number of passes per biopsy procedure was 1 (mean, 1.7; range, 1–6). Sedation using midazolam and fentanyl was used in 483/539 (90%). There were only 8 inadequate specimens (1.5%, [2.3, upper 95% confidence limit, fully described in Statistical Analysis]). Complications were identified in 11/539 biopsy procedures (2.0%, [2.6, upper 95% confidence limit]): 5 with severe postprocedural pain, 3 with symptomatic hemorrhage, 2 with infection, and 1 with a rash. There were no sedation‐related complications and no deaths related to the procedure.Conclusion.Real‐time, sonographic‐guided, random core‐needle liver biopsy is a safe and highly effective procedure. © 2009 Wiley Periodicals, Inc.

Effects of scoparone on dopamine biosynthesis and L‐DOPA‐induced cytotoxicity in PC12 cells

Published: January 2009

AbstractThe effects of scoparone on dopamine biosynthesis and L‐DOPA‐induced cytotoxicity in PC12 cells were investigated. PC12 cells treated with scoparone at concentrations of 100–200 μM showed a 128–136% increase in dopamine levels over the course of 24 hr. Scoparone significantly increased the secretion of dopamine into the culture medium. Under the same conditions, the activities of tyrosine hydroxylase (TH) and aromatic L‐amino acid decarboxylase (AADC) were enhanced by treatment with 200 μM scoparone for 6–48 hr, but the activity of TH was regulated for a longer period than that of AADC. The intracellular levels of cyclic AMP and Ca2+ were increased by treatment with 200 μM scoparone. The levels of TH mRNA and the phosphorylation of cyclic AMP‐response element‐binding protein (CREB) were also significantly increased by treatment with 200 μM scoparone. In addition, scoparone at a concentration of 200 μM stimulated the activities of cyclic AMP‐dependent protein kinase (PKA), protein kinase C (PKC), and Ca2+/calmodulin kinase II (CaMK II). Finally, pretreatment with 200 μM scoparone reduced the cytotoxicity induced by L‐DOPA (20–100 μM) at 24 hr. These results suggest that scoparone enhances dopamine biosynthesis by regulating TH activity and TH gene expression, which is mediated by the PKA, CREB, PKC, and CaMK II pathways, and protects cells from L‐DOPA‐induced cytotoxicity by inducing cyclic AMP‐PKA systems in PC12 cells. © 2009 Wiley‐Liss, Inc.
Decreased antioxidant enzyme activity and increased mitochondrial DNA damage in cellular models of Machado‐Joseph disease

Published: January 2009

AbstractMachado‐Joseph disease (MJD)/spinocerebellar ataxia type 3 (SCA3) is an autosomal dominant neurodegenerative disorder caused by polyglutamine expansion in the ataxin‐3 protein that confers a toxic gain of function. Because of the late onset of the disease, we hypothesize that the accumulated oxidative stress or/and defective antioxidant enzyme ability may be contributory factors in the pathogenesis of MJD. In this study, we utilized SK‐N‐SH and COS7 cells stably transfected with full‐length MJD with 78 polyglutamine repeats to examine any alterations in the antioxidant activity. We demonstrated a significant reduction in the ratio of GSH/GSSG and total glutathione content (GSH + 2× GSSG) in mutant MJD cells compared with the wild‐type cells under normal or stressful conditions. We also showed that both SK‐N‐SH‐MJD78 and COS7‐MJD78‐GFP cell lines have lower activities of catalase, glutathione reductase, and superoxide dismutase compared with the wild‐type cell lines. In addition, it is known that, when cells are under oxidative stress, the mitochondrial DNA is prone to damage. Our results demonstrated that mitochondrial DNA copy numbers are decreased in mutant cells and SCA3 patients' samples compared with the normal controls. Furthermore, the amount of common mitochondrial DNA 4,977‐bp deletion is higher in SCA3 patients compared with that in normal individuals. Overall, mutant ataxin‐3 may influence the activity of enzymatic components to remove O2− and H2O2 efficiently and promote mitochondrial DNA damage or depletion, which leads to dysfunction of mitochondria. Therefore, we suggest that the cell damage caused by greater oxidative stress in SCA3 mutant cells plays an important role, at least in part, in the disease progression. © 2009 Wiley‐Liss, Inc.
Complicated recessive dystonia parkinsonism syndromes
Authors: Schneider Susanne A. , Bhatia Kailash P. , Hardy John 
Published: January 2009

AbstractIn addition to pure PD and pure dystonic syndromes, there are a group of disorders with overlapping features. The differential diagnosis of these dystonia parkinsonism syndromes can be complex. In view of the growing list of recognized disorders and recent advances in genetics, we review the autosomal recessive forms of dystonia parkinsonism, summarizing clinical presentations, results of investigations, and response to treatment of gene‐proven cases. We concentrate on PANK2‐, PLA2G6‐, ATP13A2‐, FBX07, TAF1‐, and PRKRA‐associated neurodegeneration. Parkin, PINK1, and DJ‐1 are also briefly reviewed. © 2009 Movement Disorder Society
The effect of growth on stable nitrogen isotope ratios in subadult bone collagen
Authors: Waters‐Rist A. L. , Katzenberg M. A. 
Published: January 2009

AbstractStable nitrogen isotopes have been used to reconstruct infant feeding practices as nursing infants have elevated δ15N ratios compared with their mothers. However, infancy is also a time of rapid growth, which may alter nitrogen isotope diet‐to‐tissue spacing. Several studies have documented a decrease in δ15N during growth in tissues with relatively fast accretion rates. This study investigates the effect that the growth of long bones, via collagen accretion, has on δ15N ratios. Long bones from individuals aged seven to nineteen years were obtained from a protohistoric ossuary in Ontario, Canada. Analysis of juveniles and adolescents permitted the examination of growth in a group who were not also nursing. It is concluded that a nitrogen isotope growth effect is not detectable in bone collagen from juveniles and adolescents, because: (1) δ15N ratios are not significantly different among the epiphyses, metaphyses and diaphysis of a growing long bone; (2) δ15N ratios are not significantly different between faster‐growing versus slower‐growing metaphyses; and (3) δ15N ratios are not significantly different between bones (or areas of a bone) that are still undergoing growth, versus bones that have ceased growing. The relatively slow speed of collagen accretion may explain why a growth effect is not manifested. Ultimately this research lends support to the use of nitrogen isotopes from bone collagen for infant feeding reconstructions. Copyright © 2009 John Wiley & Sons, Ltd.
Diffusion and morphological properties of syndiotactic polypropylene (sPP) films
Authors: Yamashita Kohtaro , Fujiwara Narumi , Fujikawa Yuichiro , Nakaoki Takahiko , Chiu Wen‐Yen , Stroeve Pieter 
Published: January 2009

AbstractFour different fabrication procedures were used for casting thin films of syndiotactic polypropylene (sPP). A hot press system operated at 200°C and 30 MPa pressure was used to melt polypropylene powder and make the cast films. Different cooling procedures were used to anneal the films, including cooling in liquid nitrogen (LN), ice water, and air at room temperature (RT). The morphological and mass transfer properties of the films were studied with XRD, polarized optical microscopy, bulk flow, and diffusion experiments. All sPP films contained amorphous and crystalline phases. The crystalline phase was determined to be disordered Form I. The sPP films annealed with LN had the lowest crystallinity whereas the sPP films cooled in air at RT had the highest crystallinity. Diffusion of toluene in the films and comparison with Maxwell's equation indicated that the crystalline phase mass permeability is much lower than the amorphous phase, which causes films with low crystallinity to have a higher effective diffusion constant and permeability compared with high crystallinity films.
