Increasing temperature and productivity change biomass, trophic pyramids and community‐level omega‐3 fatty acid content in subarctic lake food webs
2021
Climate change in the Arctic is outpacing the global average and land-use is intensifying due to exploitation of previously inaccessible or unprofitable natural resources. A comprehensive understanding of how the joint effects of changing climate and productivity modify lake food web structure, biomass, trophic pyramid shape and abundance of physiologically essential biomolecules (omega-3 fatty acids) in the biotic community is lacking. We conducted a space-for-time study in 20 subarctic lakes spanning a climatic (+3.2 degrees C and precipitation: +30%) and chemical (dissolved organic carbon: +10 mg/L, total phosphorus: +45 mu g/L and total nitrogen: +1,000 mu g/L) gradient to test how temp…
Evaluation of the efficacy of a new insecticide paint against malaria vectors
2015
La malaria continúa siendo un problema de salud pública global. Se calcula que en el mundo hay 3.300 millones de personas en 97 países y territorios que corren el riesgo de padecer el paludismo, y que para 1.200 millones ese riesgo es elevado (WHO, 2014). El control de la malaria a gran escala está altamente basado en al control del vector, principalmente mediante el uso de mosquiteras tratadas con insecticidas de larga duración (LLINs), y en menor medida, el Rociamiento Residual Intradomiciliario. Todos los tratamientos recomendados de LLINs y la mayoría del Rociamiento Residual Intradomiciliario se basan en el uso de piretroides. La creciente resistencia de los vectores de malaria a los p…
Elämänlaatu päihdeongelmaisen läheisellä
2010
Tutkimuksen tarkoituksena oli selvittää päihdeongelmaisten henkilöiden läheisten elämänlaatua. Tutkittavat olivat Minnesota-hoidon perushoidossa olevien päihdeongelmaisten täysi-ikäisiä läheisiä (n = 41), joiden elämänlaatua tutkittiin Maailman terveysjärjestön (WHO) WHOQOL-BREF-kyselyllä ja läheissuhteen etäisyyden kyselyllä. Tutkimuksen tavoitteena oli tutkia läheisten yleistä elämänlaatua ja terveystyytyväisyyttä sekä fyysistä, henkistä ja sosiaalista elämänlaatua ja elämänlaadun ympäristöulottuvuutta. Lisäksi tarkasteltiin yleisen elämänlaadun ja terveystyytyväisyyden yhteyttä elämänlaadun ulottuvuuksiin sekä läheisen taustatietojen ja läheissuhteen etäisyyden yhteyttä koettuun elämänla…

The association of the availability of offline gay scenes and national tolerance of homosexuality with gay and bisexual men's sexual online dating be…
2020
Abstract Based on a uses and gratifications perspective on media use, in this paper I analyze the important role played by dating sites for men who have sex with men (MSM) in their efforts to find offline sexual partners. To do so, I conducted two quantitative surveys. In Study 1, I compared the online dating behavior of 12,328 MSM from Germany and Austria with the availability of offline sexual gay venues and how frequently MSM visit such venues. In Study 2, I used a global sample of 30,789 MSM to compare the frequency and recency of online dates of men living in countries that support male homosexuality and those in countries that criminalize it. The findings suggest that MSM-specific dat…
Absolute targets for HCV elimination and national health policy paradigms: Foreseeing future requirements
2021
The World Health Organization (WHO) targets for eliminating HCV by 2030 may be overambitious for many high-income countries. Recent analyses (ie, data from 2017 to 2019) show that only 11 countries are on track for meeting WHO’s elimination targets. For a country to be truly on track, it is important that the majority of infected individuals be identified and treated. There is still a need for country and population-specific evaluations within the different HCV screening and treatment strategies available, in order to assess their cost-effectiveness and sustainability and support an evidence-based policy for HCV elimination. Any health policy model is affected by the diversity and quality o…
Dependence of T-lymphocyte activation on the extent of cellular damage
2010
Mechanically damaged cells release intracellular substances, resulting in the activation of CD4- and CD8-positive T-lymphocytes. The goal of this investigation was to quantify and compare fractions of activated CD4- and CD8-positive T-lymphocytes, based on the quantity of damaged cells in a given blood sample. Blood samples were mechanically stressed by vortexing intensely. Subsequently, different quantities of distressed blood samples were mixed with samples of fresh, whole blood. Afterwards, the extent of CD4- and CD8-positive T-cell activation was examined in the mixture by flow cytometry. Sine-like curves of T-cell activation were observed for both CD4- (T-helper mediated) and CD8- (cyt…
The seroepidemiology of pertussis in Australia during an epidemic period
2006
Studying the epidemiology of pertussis and impact of differing vaccine schedules is difficult because of differing methods of case ascertainment. The advent of internationally standardized serological diagnosis for recent infection has allowed comparison of age-specific pertussis infection among European countries and was applied in Australia at the time of a major national epidemic. In 1997 and 1998, a nationally representative serum bank using residual sera from diagnostic laboratories was established. Measurement of pertussis toxin (PT) IgG level was conducted by a reference laboratory using an enzyme-linked immunosorbent assay standardized for a number of European countries. A titre of …
El papel desempeñado por los programas país de la Organización Mundial de la Salud en el desarrollo de la virología en España, 1951-1975
2020
Abstract Within the framework of recent historiography about the role of the World Health Organization (WHO) in modernizing public health and the multifaceted concept of global health, this study addresses the impact of the WHO’s “country programs” in Spain from the time it was admitted to this organization in 1951 to 1975. This research adopts a transnational historical perspective and emphasizes attention to the circulation of health knowledge, practices, and people, and focuses on the Spain-0001 and Spain-0025programs, their role in the development of virology in Spain, and the transformation of public health. Sources include historical archives (WHO, the Spanish National Health School),…
The Effectiveness of Physical Exercise on Bone Density in Osteoporotic Patients
2018
Physical exercise is considered an effective means to stimulate bone osteogenesis in osteoporotic patients. The authors reviewed the current literature to define the most appropriate features of exercise for increasing bone density in osteoporotic patients. Two types emerged: (1) weight-bearing aerobic exercises, i.e., walking, stair climbing, jogging, and Tai Chi. Walking alone did not appear to improve bone mass; however it is able to limit its progressive loss. In fact, in order for the weight-bearing exercises to be effective, they must reach the mechanical intensity useful to determine an important ground reaction force. (2) Strength and resistance exercises: these are carried out with…
