Task-Modulated Corticocortical Synchrony in the Cognitive-Motor Network Supporting Handwriting

2019

Abstract Both motor and cognitive aspects of behavior depend on dynamic, accurately timed neural processes in large-scale brain networks. Here, we studied synchronous interplay between cortical regions during production of cognitive-motor sequences in humans. Specifically, variants of handwriting that differed in motor variability, linguistic content, and memorization of movement cues were contrasted to unveil functional sensitivity of corticocortical connections. Data-driven magnetoencephalography mapping (n = 10) uncovered modulation of mostly left-hemispheric corticocortical interactions, as quantified by relative changes in phase synchronization. At low frequencies (~2–13 Hz), enhanced …

Sexual behaviors in male sex workers in Spain: Modulating factors

2013

This study analyzed how the culture of origin, educational level, sexual orientation, and experience of male sex workers may mediate their commercial sexual behaviors. A total of 100 Spanish agency male sex workers were interviewed. Most of them were young men, Latin American, homosexual, and had middle-level education. Our results showed that cultural differences and sexual orientation could influence male sex workers when engaging in sexual behaviors with their clients. Social and health projects with male sex workers may have to take into account sexual myths and taboos related to sexual orientation and cultural differences.

Mutations in the gene encoding the basal body protein RPGRIP1L, a nephrocystin-4 interactor, cause Joubert syndrome.

Peters, T.A./0000-0001-8443-5500; van Beersum, Sylvia E.C./0000-0002-4552-2908; Cremers, Frans/0000-0002-4954-5592; Roepman, Ronald/0000-0002-5178-8163 WOS: 000247619800019 PubMed: 17558407 Protein- protein interaction analyses have uncovered a ciliary and basal body protein network that, when disrupted, can result in nephronophthisis ( NPHP), Leber congenital amaurosis, Senior- Loken syndrome ( SLSN) or Joubert syndrome ( JBTS)(1-6). However, details of the molecular mechanisms underlying these disorders remain poorly understood. RPGRIP1- like protein ( RPGRIP1L) is a homolog of RPGRIP1 ( RPGR-interacting protein 1), a ciliary protein defective in Leber congenital amaurosis(7,8). We show t…

Perioperative nonspecific histamine release : a new classification by aetiological mechanisms and evaluation of their clinical relevance

1993

As a consequence of the performance of a randomized controlled clinical trial on perioperative histamine release and cardiovascular and respiratory disturbances, several types of increases in plasma histamine had to be distinguished instead of only two which existed at the beginning of the study: drug-induced allergic and pseudoallergic reactions. First of all, the new classification by aetiology (clinical epidemiology) was derived from a meta-analysis (secondary analysis) of the most recent literature. According to that histamine release in the perioperative period has several, different causes and is involved in several, different disease manifestations. A clear distinction (classificatio…

Desires and intentions for fatherhood: A comparison of childless gay and heterosexual men in Germany.

2018

The present study explores the motivation for fatherhood in a sample of childless German gay and heterosexual men aged 18 to 40 years (N = 628 + 638). Referring to the theory of planned behavior (TPB), three potential predictors were considered: the individual's attitude toward having children, perceived attitudes of significant others toward fatherhood, and anticipated parental self-efficacy. Regarding fathering motivation, the general desire to become a father was differentiated from the more concrete fathering intention. Level- and structure-oriented analyses were combined in an innovative way. Consistent with previous research, gay participants reported weaker fathering desires and inte…

Diffuse Type of Giant-Cell Tumor of Tendon Sheath: An Ultrastructural Study of Two Cases With Cytogenetic Support

2002

Two cases of the diffuse type of giant-cell tumor of the tendon sheath (GCTTS) are described. Both tumors arose in the vicinity of large joints of the lower extremity, showing similar clinical and radiological features. Histologically, a proliferation of polygonal mononuclear cells was seen, together with osteoclastlike giant cells, foam cells, and siderophages. The tumors were poorly delineated, displaying an infiltrative pattern into the neighboring soft tissues. Immunohistochemically, strong expression of vimentin, neuron-specific enolase, A1-antitrypsin, and CD68 was found in both mono- and multinucleated tumor cells. At the ultrastructural level, mononuclear cells revealed a diverse mo…

Polymorphism of C'3 in German, Bulgarian, Iranian and Angola population

1973

Using agarose gel electrophoresis, C'3 was typed in 4 populations. The gene frequencies of the common allele C'3S in these 4 populations were Germans (0.8071), Bulgarians (0.8149), Iranians (0.7920) and Angola (0.9532). The results are discussed.

That Man Behind the Curtain: Investigating the Sexual Online Dating Behavior of Men Who Have Sex With Men but Hide Their Same-Sex Sexual Attraction i…

2016

This study investigates how men who have sex with men (MSM) use chat and dating sites based on theories of stigma-related offline behavior and online self-disclosure. We hypothesize that hidden MSM (those who self-label as heterosexual or who hide their same-sex sexual attraction from family, friends, acquaintances, or a female romantic partner) differ from open MSM in how they behave on gay chat and dating sites and in offline gay venues. Drawing on a survey of 12,002 MSM, we show that hidden MSM tend to mask their identity on gay chat and dating sites while avoiding offline gay venues. They also focus more strongly on online sexual activities (e.g., masturbating during online chats) when …

Differences in Visual Attention Patterns to Sexually Mature and Immature Stimuli Between Heterosexual Sexual Offenders, Nonsexual Offenders, and Nono…

2018

Men, whether gynephilic or androphilic, show both early and late attention toward adults and not toward children. We examined early and late visual attention to sexually mature versus immature stimuli in four groups of heterosexual men: sexual offenders against children (SOAC = 18), sexual offenders against adults (SOAA = 16), nonsexual offenders (NSO = 18), and nonoffending men (NOM = 19). We simultaneously presented adult and child stimuli and measured time to first fixation, number of first fixations, total duration of fixation, and fixation count to four areas of interest: entire body, then face, chest, and pelvis. We found a significant interaction where only SOAC tended to fixate more…
