Young masculinities across five European countries : performing under pressure

© 2019 Informa UK Limited, trading as Taylor & Francis Group. We present an analysis of young masculinities based on young peoples’ perspectives derived from a project on sexual bullying. Our qualitative data are based on 41 focus groups with 253 young people (male and female) aged 13–18 across five European countries (Bulgaria, Italy, Latvia, Slovenia and England) as well as questionnaire responses. The data were analysed using thematic analysis (Braun, V., and V. Clarke. 2006. “Using Thematic Analysis in Psychology.” Qualitative Research in Psychology 3 (2): 77–101). Our analysis pointed to the prevalence of sexist and homophobic behaviours among young men, who were themselves concerned with their ‘masculine’ reputations by appearing physically tough, (hetero)sexually active and emotionally closed. The young women in our sample also depicted many young men as immature, naïve and superficial. At the same time, the young men were portrayed as more calm, rational and resilient compared to their female counterparts, with young men insisting that any ‘problematic’ or ‘bullying’ behaviour amounted to harmless fun. Our analysis suggests that young men are performing gender and sexuality under the influence of conventional norms which prioritise homosociality, humour and status, which shy away from challenging sexist or homophobic practices, and which inhibit reporting themselves as victims of bullying. The implications for young masculinities and social change are discussed

Safety and immunogenicity of a bivalent cytomegalovirus DNA vaccine in healthy adult subjects.

BACKGROUND: VCL-CB01, a candidate cytomegalovirus (CMV) DNA vaccine that contains plasmids encoding CMV phosphoprotein 65 (pp65) and glycoprotein B (gB) to induce cellular and humoral immune responses and that is formulated with poloxamer CRL1005 and benzalkonium chloride to enhance immune responses, was evaluated in a phase 1 clinical trial. METHODS: VCL-CB01 was evaluated in 44 healthy adult subjects (22 CMV seronegative and 22 CMV seropositive) 18-43 years old. Thirty-two subjects received 1- or 5-mg doses of vaccine on a 0-, 2-, and 8-week schedule, and 12 subjects received 5-mg doses of vaccine on a 0-, 3-, 7-, and 28-day schedule. RESULTS: Overall, the vaccine was well tolerated, with no serious adverse events. Local reactions included mild to moderate injection site pain and tenderness, induration, and erythema. Systemic reactions included mild to moderate malaise and myalgia. All reactions resolved without sequelae. Through week 16 of the study, immunogenicity, as measured by enzyme-linked immunosorbant assay and/or ex vivo interferon (IFN)-gamma enzyme-linked immunospot assay, was documented in 45.5% of CMV-seronegative subjects and in 25.0% of CMV-seropositive subjects who received the full vaccine series, and 68.1% of CMV-seronegative subjects had memory IFN-gamma T cell responses at week 32. CONCLUSION: The safety and immunogenicity data from this trial support further evaluation of VCL-CB01

Contrastive prosody and the subsequent mention of alternatives during discourse processing

Linguistic research has long viewed prosody as an important indicator of information structure in intonationally rich languages like English. Correspondingly, numerous psycholinguistic studies have shown significant effects of prosody, particularly with respect to the immediate processing of a prosodically prominent phrase. Although co-reference resolution is known to be influenced by information structure, it has been less clear whether prosodic prominence can affect decisions about next mention in a discourse, and if so, how. We present results from an open-ended story continuation task, conducted as part of a series of experiments that examine how prosody influences the anticipation and resolution of co-reference. Overall results from the project suggest that prosodic prominence can increase or decrease reference to a saliently pitch-accented phrase, depending on additional circumstances of the referential decision. We argue that an adequate account of prosody’s role in co-reference requires consideration of how the processing system interfaces with multiple levels of linguistic representation

The Ligand Binding Domain of GCNF Is Not Required for Repression of Pluripotency Genes in Mouse Fetal Ovarian Germ Cells

In mice, successful development and reproduction require that all cells, including germ cells, transition from a pluripotent to a differentiated state. This transition is associated with silencing of the pluripotency genes Oct4 and Nanog. Interestingly, these genes are repressed at different developmental timepoints in germ and somatic cells. Ovarian germ cells maintain their expression until about embryonic day (E) 14.5, whereas somatic cells silence them much earlier, at about E8.0. In both somatic cells and embryonic stem cells, silencing of Oct4 and Nanog requires the nuclear receptor GCNF. However, expression of the Gcnf gene has not been investigated in fetal ovarian germ cells, and whether it is required for silencing Oct4 and Nanog in that context is not known. Here we demonstrate that Gcnf is expressed in fetal ovarian germ cells, peaking at E14.5, when Oct4 and Nanog are silenced. However, conditional ablation of the ligand-binding domain of Gcnf using a ubiquitous, tamoxifen-inducible Cre indicates that Gcnf is not required for the down-regulation of pluripotency genes in fetal ovarian germ cells, nor is it required for initiation of meiosis and oogenesis. These results suggest that the silencing of Oct4 and Nanog in germ cells occurs via a different mechanism from that operating in somatic cells during gastrulation.Howard Hughes Medical InstituteNational Institutes of Health (U.S.) (2R01HG00257-20)National Human Genome Research Institute (U.S.) (2R01HG00257-20

Noise-Aided Logic in an Electronic Analog of Synthetic Genetic Networks

We report the experimental verification of noise-enhanced logic behaviour in an electronic analog of a synthetic genetic network, composed of two repressors and two constitutive promoters. We observe good agreement between circuit measurements and numerical prediction, with the circuit allowing for robust logic operations in an optimal window of noise. Namely, the input-output characteristics of a logic gate is reproduced faithfully under moderate noise, which is a manifestation of the phenomenon known as Logical Stochastic Resonance. The two dynamical variables in the system yield complementary logic behaviour simultaneously. The system is easily morphed from AND/NAND to OR/NOR logi

Zebrafish Tmem230a cooperates with the Delta/Notch signaling pathway to modulate endothelial cell number in angiogenic vessels

During embryonic development, new arteries, and veins form from preexisting vessels in response to specific angiogenic signals. Angiogenic signaling is complex since not all endothelial cells exposed to angiogenic signals respond equally. Some cells will be selected to become tip cells and acquire migration and proliferation capacity necessary for vessel growth while others, the stalk cells become trailer cells that stay connected with pre-existing vessels and act as a linkage to new forming vessels. Additionally, stalk and tip cells have the capacity to interchange their roles. Stalk and tip cellular responses are mediated in part by the interactions of components of the Delta/Notch and Vegf signaling pathways. We have identified in zebrafish, that the transmembrane protein Tmem230a is a novel regulator of angiogenesis by its capacity to regulate the number of the endothelial cells in intersegmental vessels by co-operating with the Delta/Notch signaling pathway. Modulation of Tmem230a expression by itself is sufficient to rescue improper number of endothelial cells induced by aberrant expression or inhibition of the activity of genes associated with the Dll4/Notch pathway in zebrafish. Therefore, Tmem230a may have a modulatory role in vessel-network formation and growth. As the Tmem230 sequence is conserved in human, Tmem230 may represent a promising novel target for drug discovery and for disease therapy and regenerative medicine in promoting or restricting angiogenesis
