    Aging effect on nectar production in two clones of Asclepias syriaca

    In common milkweed ( Asclepias syriaca ), flower nectar volumes, concentration and sugar production varied according to the age of the sampled blossoms. In individual blossoms, nectar production peaked daily at 0800 hr. Peak production during the life of the flower occurred on the second day of flowering, 50 h after anthesis, and nectar production ceased after 120 h. The amount and quality of nectar were affected by microclimatic conditions and varied between clones. However, the same secretory patterns were found in all flowers studied. This age dependent nectar secretion combined with the sequential mode of flowering found on a single stem, results in substantial reward for extended periods to nectar feeders.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47744/1/442_2004_Article_BF00378227.pd

    Capacity shortfalls hinder the performance of marine protected areas globally

    Marine protected areas (MPAs) are increasingly being used globally to conserve marine resources. However, whether many MPAs are being effectively and equitably managed, and how MPA management influences substantive outcomes remain unknown. We developed a global database of management and fish population data (433 and 218 MPAs, respectively) to assess: MPA management processes; the effects of MPAs on fish populations; and relationships between management processes and ecological effects. Here we report that many MPAs failed to meet thresholds for effective and equitable management processes, with widespread shortfalls in staff and financial resources. Although 71% of MPAs positively influenced fish populations, these conservation impacts were highly variable. Staff and budget capacity were the strongest predictors of conservation impact: MPAs with adequate staff capacity had ecological effects 2.9 times greater than MPAs with inadequate capacity. Thus, continued global expansion of MPAs without adequate investment in human and financial capacity is likely to lead to sub-optimal conservation outcomes

    The effectiveness of mobile-health technologies to improve health care service delivery processes: a systematic review and meta-analysis.

    BACKGROUND: Mobile health interventions could have beneficial effects on health care delivery processes. We aimed to conduct a systematic review of controlled trials of mobile technology interventions to improve health care delivery processes. METHODS AND FINDINGS: We searched for all controlled trials of mobile technology based health interventions using MEDLINE, EMBASE, PsycINFO, Global Health, Web of Science, Cochrane Library, UK NHS HTA (Jan 1990-Sept 2010). Two authors independently extracted data on allocation concealment, allocation sequence, blinding, completeness of follow-up, and measures of effect. We calculated effect estimates and we used random effects meta-analysis to give pooled estimates. We identified 42 trials. None of the trials had low risk of bias. Seven trials of health care provider support reported 25 outcomes regarding appropriate disease management, of which 11 showed statistically significant benefits. One trial reported a statistically significant improvement in nurse/surgeon communication using mobile phones. Two trials reported statistically significant reductions in correct diagnoses using mobile technology photos compared to gold standard. The pooled effect on appointment attendance using text message (short message service or SMS) reminders versus no reminder was increased, with a relative risk (RR) of 1.06 (95% CI 1.05-1.07, I(2) = 6%). The pooled effects on the number of cancelled appointments was not significantly increased RR 1.08 (95% CI 0.89-1.30). There was no difference in attendance using SMS reminders versus other reminders (RR 0.98, 95% CI 0.94-1.02, respectively). To address the limitation of the older search, we also reviewed more recent literature. CONCLUSIONS: The results for health care provider support interventions on diagnosis and management outcomes are generally consistent with modest benefits. Trials using mobile technology-based photos reported reductions in correct diagnoses when compared to the gold standard. SMS appointment reminders have modest benefits and may be appropriate for implementation. High quality trials measuring clinical outcomes are needed.

    Abstract: One of the many great things about living in the Netherlands is the excellent standard of Dutch healthcare, rated as the best in Europe. The Netherlands tops the list of 34 nations in the 2012 Euro Health Consumer Index (the ‘industry standard’ of modern healthcare) and spends 11.9 percent of GDP on health, being the second only after the United States. Plus, almost all the doctors speak excellent English, making healthcare in the Netherlands very accessible to expats. The purpose of the research is to investigate the health sector in the Netherlands and to connect it to the European systems and global requirements. Methods. Conducted research was focused on analysis, comparison, deduction or induction methods. Medicine in the Netherlands is taught differently than in Europe, both in terms of the approach to the subject and timeline to qualification. A visitor to the Netherlands faces no special health risks, as the overall health conditions are excellent. No special inoculations are required. Any necessary immunization is available locally. Although Dutch law is strict about commercial processing, cooking, handling, and serving of foods, consumers are advised to show caution when using eggs and preparing poultry, as salmonella bacteria has been found in these products. Tap water is of excellent quality and safe to drink. Dutch medical care is of high quality and is comparable to the medical care one finds throughout Western Europe. Diagnostic laboratories and specialists in all fields of medicine are available. Hospitals are well-equipped, and maternity hospitals and many clinics are available. Most doctors and dentists speak English. Most medicines are available locally. They may not, however, be the same brand names as those used in the United States and prices are generally higher. Tourists should bring a supply of the medicine that they know they will need whilst abroad and provide proper documentation

    Abstract: The issue of medical cooperation raises many questions current and controversial, which are the focus of interest in socio-political and legal, such as debates on instruments to combat the high costs, the public health system, legislation aimed at ensuring health, tobacco consumption, alcohol, obesity and others. Public health legislation deals with the framework conditions, legal and social aspects of public health, protection and deployment the law of public health on tobacco. The aim of this study is to identify the degree to which economic freedom correlates with indicators of development, health and economic cooperation in medicine field. In this regard, we consider useful to investigate how the correlation indicators of policy Health – 2020 with global and European economic development. Research methods are located in estimating the degree of international cooperation in the medicine field through statistical methods, comparison, graphics, deduction or induction.The results allow to formulate a whole picture regarding international cooperation in the field of medicine, combating different diseases but human vices as obesity, tobacco use, alcohol etc. Facilitation of cooperation in research and innovation is the key to bridging the gap between research and demand in different countries and regions
