Local is not always better: the impact of climate information on values, behavior and policy support

In the current research, we experimentally examined the effect of providing local or global information about the impacts of climate change on individuals’ perceived importance of climate change and on their willingness to take action to address it, including policy support. We examined these relationships in the context of individuals’ general value orientations. Our findings, from 99 US residents, suggest that different kinds of climate information (local, global, or none) interact with values vis-à-vis our dependent variables. Specifically, while self-transcendent values predict perceived importance and pro-environmental behavior across all three information conditions, the effect on policy support is less clear. Furthermore, we detected a “reactance effect” where individuals with self-enhancing values who read local information thought that climate change was less important and were less willing to engage in pro-environmental behavior and support policy than self-enhancing individuals in the other information conditions. These results suggest that policy makers and public communicators may want to be cognizant of their audience’s general value orientation. Local information may not only be ineffective but may also prove counterproductive with individuals whose value orientations are more self-enhancing than self-transcendent

Prostate response to prolactin in sexually active male rats

BACKGROUND: The prostate is a key gland in the sexual physiology of male mammals. Its sensitivity to steroid hormones is widely known, but its response to prolactin is still poorly known. Previous studies have shown a correlation between sexual behaviour, prolactin release and prostate physiology. Thus, here we used the sexual behaviour of male rats as a model for studying this correlation. Hence, we developed experimental paradigms to determine the influence of prolactin on sexual behaviour and prostate organization of male rats. METHODS: In addition to sexual behaviour recordings, we developed the ELISA procedure to quantify the serum level of prolactin, and the hematoxilin-eosin technique for analysis of the histological organization of the prostate. Also, different experimental manipulations were carried out; they included pituitary grafts, and haloperidol and ovine prolactin treatments. Data were analyzed with a One way ANOVA followed by post hoc Dunnet test if required. RESULTS: Data showed that male prolactin has a basal level with two peaks at the light-dark-light transitions. Consecutive ejaculations increased serum prolactin after the first ejaculation, which reached the highest level after the second, and started to decrease after the third ejaculation. These normal levels of prolactin did not induce any change at the prostate tissue. However, treatments for constant elevations of serum prolactin decreased sexual potency and increased the weight of the gland, the alveoli area and the epithelial cell height. Treatments for transient elevation of serum prolactin did not affect the sexual behaviour of males, but triggered these significant effects mainly at the ventral prostate. CONCLUSION: The prostate is a sexual gland that responds to prolactin. Mating-induced prolactin release is required during sexual encounters to activate the epithelial cells in the gland. Here we saw a precise mechanism controlling the release of prolactin during ejaculations that avoid the detrimental effects produced by constant levels. However, we showed that minor elevations of prolactin which do not affect the sexual behaviour of males, produced significant changes at the prostate epithelium that could account for triggering the development of hyperplasia or cancer. Thus, it is suggested that minute elevations of serum prolactin in healthy subjects are at the etiology of prostate abnormal growth

Synthetic Double-Stranded RNAs Are Adjuvants for the Induction of T Helper 1 and Humoral Immune Responses to Human Papillomavirus in Rhesus Macaques

Toll-like receptor (TLR) ligands are being considered as adjuvants for the induction of antigen-specific immune responses, as in the design of vaccines. Polyriboinosinic-polyribocytoidylic acid (poly I:C), a synthetic double-stranded RNA (dsRNA), is recognized by TLR3 and other intracellular receptors. Poly ICLC is a poly I:C analogue, which has been stabilized against the serum nucleases that are present in the plasma of primates. Poly I:C12U, another analogue, is less toxic but also less stable in vivo than poly I:C, and TLR3 is essential for its recognition. To study the effects of these compounds on the induction of protein-specific immune responses in an animal model relevant to humans, rhesus macaques were immunized subcutaneously (s.c.) with keyhole limpet hemocyanin (KLH) or human papillomavirus (HPV)16 capsomeres with or without dsRNA or a control adjuvant, the TLR9 ligand CpG-C. All dsRNA compounds served as adjuvants for KLH-specific cellular immune responses, with the highest proliferative responses being observed with 2 mg/animal poly ICLC (p = 0.002) or 6 mg/animal poly I:C12U (p = 0.001) when compared with immunization with KLH alone. Notably, poly ICLC—but not CpG-C given at the same dose—also helped to induce HPV16-specific Th1 immune responses while both adjuvants supported the induction of strong anti-HPV16 L1 antibody responses as determined by ELISA and neutralization assay. In contrast, control animals injected with HPV16 capsomeres alone did not develop substantial HPV16-specific immune responses. Injection of dsRNA led to increased numbers of cells producing the T cell–activating chemokines CXCL9 and CXCL10 as detected by in situ hybridization in draining lymph nodes 18 hours after injections, and to increased serum levels of CXCL10 (p = 0.01). This was paralleled by the reduced production of the homeostatic T cell–attracting chemokine CCL21. Thus, synthetic dsRNAs induce an innate chemokine response and act as adjuvants for virus-specific Th1 and humoral immune responses in nonhuman primates

Territorio, lugares y salud : redimensionar lo espacial en salud pública

RESUMEN: El propósito de este escrito es avanzar en la lectura del proceso de salud-enfermedad en clave territorial. La teorización sobre el vínculo salud y ambiente debe extenderse desde las tipologías médicas, y su énfasis en la distribución del riesgos ambientales (físico, biológico, químico), hacia el reconocimiento de la producción social y subjetiva de los territorios. Para avanzar en esta teorización la salud pública debe enriquecerse con la integración de nociones propias de las ciencias sociales como la apropiación del espacio, territorio-territorialidades y lugares. Además, ha de orientarse desde una mirada escalar hacia los microterritorios, pues es en el escenario de los territorios locales y en los lugares cotidianos de la vida, donde se concretan los modos de vivir, de enfermar y de construir salud

Elinsiirron saaneen nuoren siirtyminen lasten ja nuorten hoitotyöstä aikuisten terveyspalveluiden käyttäjäksi

Opinnäytetyömme tarkoituksena on kuvata saumaton, hoitoon sitoutumista tukeva hoitopolku nuoren elinsiirtopotilaan siirtyessä lasten ja nuorten hoitotyöstä aikuisten terveyspalvelujen käyttäjäksi. Työmme on osa lasten ja nuorten hoitotyön osaamisen tulevaisuuden hanketta. Hankkeen tarkoituksena on uusien toimintakäytäntöjen luominen, verkostomaisen työskentelyn vahvistaminen, sekä saumattomien hoitopolkujen kehittäminen. Hankkeessa yhteistyökumppaneina ovat HYKS Naisten- ja lastentautien tulosyksikkö, Metropolia ammattikorkeakoulun Hoitotyön koulutusohjelma ja Tampereen yliopiston Hoitotieteen laitos. Työssämme keskitymme potilaan siirtymävaiheen solmukohtiin, kuvaamme nykyisen hoitopolun ja pyrimme löytämään näkökulmia sekä toimintamalleja, jotka antaisivat nuorelle, hänen perheelleen sekä hoitoyksikölle valmiuksia siirtymisprosessin vaiheisiin. Työssämme keskitymme nuorten kehittymishaasteisiin ja pyrimme kartoittamaan nuorten hoitomyönteisyyttä ja vastaanottavaisuutta edistäviä keinoja ja välineitä. Opinnäytetyömme aihe on uusi hoitotieteellisen tutkimuksen kohde ja löytämämme materiaali on luonteeltaan täsmällistä, tuoretta ja vastaa hyvin työmme edistymisen vaateisiin. Käytimme työssämme kvantitatiivista tutkimusmenetelmää. Tutkimustyön tarve sekä prosessin kehittäminen potilaan tarpeita vastaavaksi tällä hoitotyön saralla on erittäin tärkeää. Kansainvälisesti siirtymisessä koetaan haastavimmaksi prosessin alkamisen äkillisyys, riittämätön tiedonkulku lasten ja aikuisten puolen välillä ja tätä kautta hoidon jatkuvuuden kankeus. Toisin sanoen siirtymiseen valmistavien toimintojen aikaistaminen, kirjallinen informaatio ja sujuvampi yhteistyö palveluiden tarjoajien välillä, ovat suurimmat kehittymishaasteet

Public Real Estate Assets and the Metropolitan Strategic Plan in Italy. The Two Cases of Milan and Cagliari

The process of economic transition from the old to the new economy produces significant effects also on cities and territories. The change in the production cy-cles has led to numerous and significant phenomena of delocalization and conse-quent abandonment of buildings and infrastructures, according to the markets. In Italy, starting from the 70s, the divestment of industrial areas and the more recent Federalism Law have increased the interest on reuse of public properties as an act proper to municipal urban planning. However, the public real estate management (PREM) and the choice of new urban functions to be assigned represents a diffi-cult challenge still today, at all levels of government, including that of the Metro-politan Cities (MCs), established by the Delrio Law. MCs, which define devel-opment strategies in a medium-term period through the Metropolitan Strategic Plan (SP), represent a great opportunity to integrate PREM and public policies objectives. Within this framework, the aim of the present study is to evaluate meaning and roles recognized to the public assets in the SP drawn up by the Met-ropolitan City of Milan (MCM) - Lombardy Region - and in the ongoing SP of the Metropolitan City of Cagliari (MCC) - Sardinia Region. The qualitative and quantitative analysis of the two case studies allows authors to make considera-tions on the multiple roles that public real estate can play in the context of strate-gic planning to pursue sustainable development of territories
