I Don\u27t Want to Hear About Your Dick : Communicatively Managing Stigma Surrounding Foreskin Restoration

Goffman (1963) defined stigma as an individual being unable to receive social acceptance because of a specific characteristic by being marked based on a characteristic, which can visible or invisible. This study examined how men undergoing foreskin restoration communicatively manage the stigma associated with restoring their foreskin. Through 13 interviews, I was able to thematically code using Meisenbach’s (2010) stigma management communication typology which served as an excellent theoretical fit. My results suggest that men undergoing foreskin restoration deploy several sub-strategies to manage stigma, as well as utilize multiple strategies simultaneously. Furthermore, my results indicate the possibility of new stigma management strategies as well as the concept of forced disclosure, which would make an excellent addition to the previously mentioned typology

Broadband enhancement of the magneto-optical activity of hybrid Au loaded Bi:YIG

We unravel the underlying near-field mechanism of the enhancement of the magneto-optical activity of bismuth-substituted yttrium iron garnet films (Bi:YIG) loaded with gold nanoparticles. The experimental results show that the embedded gold nanoparticles lead to a broadband enhancement of the magneto-optical activity with respect to the activity of the bare Bi:YIG films. Full vectorial near- and far-field simulations demonstrate that this broadband enhancement is the result of a magneto-optically enabled cross-talking of orthogonal localized plasmon resonances. Our results pave the way to the on-demand design of the magneto-optical properties of hybrid magneto-plasmonic circuitry.Comment: 6 Pages, 3 Figure

Anaplasma phagocytophilum Infection in Ixodes ricinus, Bavaria, Germany

Anaplasma phagocytophilum DNA was detected by real-time PCR, which targeted the msp2 gene, in 2.9% of questing Ixodes ricinus ticks (adults and nymphs; n = 2,862), collected systematically from selected locations in Bavaria, Germany, in 2006. Prevalence was significantly higher in urban public parks in Munich than in natural forests

Outbreak of leptospirosis among triathlon participants in Germany, 2006

<p>Abstract</p> <p>Background</p> <p>In August 2006, a case of leptospirosis occurred in an athlete after a triathlon held around Heidelberg and in the Neckar river. In order to study a possible outbreak and to determine risk factors for infection an epidemiological investigation was performed.</p> <p>Methods</p> <p>Participants of the triathlon were contacted by e-mail and were asked to fill out a standardized questionnaire. In addition, they were asked to supply a serum sample for laboratory diagnosis of leptospirosis. A confirmed case patient was defined as a clinical case (i.e. fever and at least one additional symptom suggestive for leptospirosis) with at least two of the following tests positive: ELISA IgM, latex agglutination testing, or microscopic agglutination testing. Rainfall and temperature records were obtained.</p> <p>Results</p> <p>A total of 142 of 507 triathletes were contacted; among these, five confirmed leptospirosis cases were found. Open wounds were identified as the only significant risk factor for illness (p = 0.02). Heavy rains that preceded the swimming event likely increased leptospiral contamination of the Neckar River.</p> <p>Discussion</p> <p>This is the first outbreak of leptospirosis related to a competitive sports event in Germany. Among people with contact to freshwater, the risk of contracting leptospirosis should be considered by health care providers also in temperate countries, particularly in the summer after heavy rains.</p

Imaging cytoplasmic cAMP in mouse brainstem neurons

<p>Abstract</p> <p>Background</p> <p>cAMP is an ubiquitous second messenger mediating various neuronal functions, often as a consequence of increased intracellular Ca²⁺levels. While imaging of calcium is commonly used in neuroscience applications, probing for cAMP levels has not yet been performed in living vertebrate neuronal tissue before.</p> <p>Results</p> <p>Using a strictly neuron-restricted promoter we virally transduced neurons in the organotypic brainstem slices which contained pre-Bötzinger complex, constituting the rhythm-generating part of the respiratory network. Fluorescent cAMP sensor Epac1-camps was expressed both in neuronal cell bodies and neurites, allowing us to measure intracellular distribution of cAMP, its absolute levels and time-dependent changes in response to physiological stimuli. We recorded [cAMP]_ichanges in the micromolar range after modulation of adenylate cyclase, inhibition of phosphodiesterase and activation of G-protein-coupled metabotropic receptors. [cAMP]_ilevels increased after membrane depolarisation and release of Ca²⁺from internal stores. The effects developed slowly and reached their maximum after transient [Ca²⁺]_ielevations subsided. Ca²⁺-dependent [cAMP]_itransients were suppressed after blockade of adenylate cyclase with 0.1 mM adenylate cyclase inhibitor 2'5'-dideoxyadenosine and potentiated after inhibiting phosphodiesterase with isobutylmethylxanthine and rolipram. During paired stimulations, the second depolarisation and Ca²⁺release evoked bigger cAMP responses. These effects were abolished after inhibition of protein kinase A with H-89 pointing to the important role of phosphorylation of calcium channels in the potentiation of [cAMP]_itransients.</p> <p>Conclusion</p> <p>We constructed and characterized a neuron-specific cAMP probe based on Epac1-camps. Using viral gene transfer we showed its efficient expression in organotypic brainstem preparations. Strong fluorescence, resistance to photobleaching and possibility of direct estimation of [cAMP] levels using dual wavelength measurements make the probe useful in studies of neurons and the mechanisms of their plasticity. Epac1-camps was applied to examine the crosstalk between Ca²⁺and cAMP signalling and revealed a synergism of actions of these two second messengers.</p
