ABSTRACT
Resumen El objetivo de este artículo es el de explorar el papel que juega, en la actualidad, la irrupción de la mediación tecnológica de la información y la comunicación en la configuración de nuevos contextos para la relación sexual. En concreto, hemos explorado una práctica determinada, el cruising, entre hombres jóvenes que tienen sexo con hombres contactado a través de las e-citas. Se ha apostado por la metodología cualitativa con la intención de recopilar los discursos sobre sexualidad, riesgos y salud que se generan y construyen entre el grupo de iguales. Según extraemos de nuestro estudio, el nuevo marco que confiere esta tecnología estaría caracterizado por (a) una mayor accesibilidad a dichas prácticas, (b) una mayor difusión de estas, (c) una mayor inmediatez de acceso a las propuestas, (d) la anticipación de lo que será ofrecido en la cita, (e) acceso anónimo que permite propuestas más atrevidas y (f) una apertura mayor a la diversidad de usuarios. Todos estos elementos confluyen en un cuadro que nos lleva a considerar una organización social renovada de la práctica sexual.
Resumo O objetivo deste artigo é explorar o papel que a irrupção da mediação tecnológica da informação e da comunicação desempenha na definição de novos contextos para a relação sexual. Em particular, explora-se uma determinada prática, o cruising entre os homens jovens que fazem sexo com homens contatados via e- encontros. Nossa aposta foi pela metodologia qualitativa, com a intenção de recolher os discursos sobre a sexualidade, a saúde e os riscos que são gerados e construídos entre o grupo de pares. De acordo com o nosso estudo, o novo quadro que oferece essa tecnologia seria marcado por: (a) uma maior acessibilidade a essas práticas; (b) uma maior divulgação das mesmas, bem como (c) um maior imediatismo de acesso para as propostas; (d) a antecipação do que vai ser oferecido no encontro; (e) acesso anônimo que permite propostas mais ousadas; e (f) uma maior abertura para a diversidade de usuários. Todos esses elementos convergem em um contexto que leva-nos a considerar uma nova organização social da prática sexual.
Abstract This article addresses the rapidly growing use of information and communication technologies in mediating new settings for sexual relations. The specific focus is on cruising among young men who have sex with men via e-dating. The study used a qualitative methodology with peer group discussions on sexuality, health, and risk. The new framework provided by technology is marked by (a) increased access to these practices, (b) greater dissemination of them, (c) greater immediacy of encounters, (d) anticipation of what will be offered during dates, (e) anonymous access, allowing bolder proposals, and (f) openness to a wider range of users. These elements converge in a framework that indicates a new social organization of sexual practice.

Orthopalladation of the phenyl ring in the cyclopalladated complex [Pd{C,N-pyl-SCHC(O)Ph}(µ-X)]2 (pyl = 2-pyridyl, X = Cl; 1·Cl) occurs upon reacting it with AgOAc (1 : 2) in MeCN to give the pincer complex [Pd{C,C,N-pyl-SCHC(O)C6H4-2}(NCMe)] (2). The nature of the base and X plays a key role because palladation neither occurs with other bases nor when AgOAc is the base and X is Br, in which case 1·OAc is obtained. In addition, complex 2 is not obtained upon refluxing 1·OAc in MeCN. Complex 2 affords complexes [Pd{C,C,N,S-pyl-SCHC(O)C6H4-2}]n, [Pd{C,C,N-pyl-SCHC(O)C6H4-2}L] (L = PPh3, (t)BuNC, XyNC) or Me4N[Pd{C,C,N-pyl-SCHC(O)C6H4-2}Cl] upon acetonitrile loss, or its replacement by neutral or anionic ligands, respectively. Some such complexes act as metallaligands towards AgClO4 or [PdCl2(NCPh)2] giving rise to heterodinuclear [{Pd{C,C,N-pyl-SCHC(O)C6H4-2}(PPh3)}{Ag(PPh3)}]ClO4 or homodinuclear [{Pd{C,C,N-pyl-SCHC(O)C6H4-2}(Cl)}{Pd(µ-Cl)}]2, [{Pd{C,C,N-pyl-SCHC(O)C6H4-2}(Cl)}{Pd(Cl)(PPh3}] complexes. Some derivatives of complexes 1 were also obtained.
ABSTRACT
BACKGROUND: Platelet function of patients with subarachnoid hemorrhage (SAH) may play an important part in both rebleeding and delayed cerebral ischemia, but little is known about aggregation pathways during the acute phase of stroke. Analgesics are used regularly in the first days after bleeding, and some can potentially inhibit the cyclooxygenase (COX) enzyme. We examined the platelet function of patients with SAH in order to describe their basal situation and determine whether the administration of intravenous nonsteroidal antiinflammatory drugs (NSAIDs) affected platelet aggregation. METHODS: Arachidonic acid (AA)-induced aggregation and the platelet function analyzer (PFA)-100 test with collagen/epinephrine cartridges were used to study a group of SAH patients that was treated with dexketoprofen and dipyrone and to compare them to patients that had received no analgesia. RESULTS: Ninety-six consecutive SAH patients prospectively enrolled in platelet studies. Twenty-seven patients were taking NSAIDs (10 on dexketoprofen and 17 on dipyrone), and there were 15 cases in the control group. AA-induced aggregation was 10% ± 3.2% for NSAIDs (mean ± standard error), specifically 17.2% ± 7% for dexketoprofen and 5.7% ± 1% for dipyrone. Aggregation in the control group was 72.4% ± 6% (P = .001). Both analgesics slowed the platelet plug formation during the PFA-100 test, with closure times of 237.2 ± 25 seconds for dexketoprofen and 198.4 ± 22 seconds for dipyrone and 138.1 ± 21 seconds in controls (P = .02). CONCLUSIONS: The administration of COX-inhibiting analgesics leads to an hypoaggregability state in the first days of SAH. Further insight into their impact on complications such as rebleeding and delayed cerebral ischemia is needed in order to optimize the headache treatment of SAH.
