Sendai five years on: reflections on the role of international law in the creation and reduction of disaster risk

This article offers a critical examination of the position of the Sendai Framework for Disaster Risk Reduction 2015-2030 within international law. It is argued that any interrogation into the role of international law must begin not with existing disaster risk reduction (DRR) laws and policies, but rather with an enquiry into the nature of disaster risk and the role of international law in its creation and reduction. It is demonstrated how, while areas such as international human rights law can be utilized to enforce obligations in support of DRR, other areas – in particular international investment law – actively work to undermine DRR efforts. In order for international law to be a productive tool in the reduction of disaster risk international lawyers must engage with critical work in disaster studies in order to explore the role that the former has played – and can play – in creating and addressing hazards, vulnerabilities and capacities

Identification and characterization of Rhipicephalus (Boophilus) microplus candidate protective antigens for the control of cattle tick infestations

The cattle ticks, Rhipicephalus (Boophilus) spp., affect cattle production in tropical and subtropical regions of the world. Tick vaccines constitute a cost-effective and environmentally friendly alternative to tick control. The recombinant Rhipicephalus microplus Bm86 antigen has been shown to protect cattle against tick infestations. However, variable efficacy of Bm86-based vaccines against geographic tick strains has encouraged the research for additional tick-protective antigens. Herein, we describe the analysis of R. microplus glutathione-S transferase, ubiquitin (UBQ), selenoprotein W, elongation factor-1 alpha, and subolesin (SUB) complementary DNAs (cDNAs) by RNA interference (RNAi) in R. microplus and Rhipicephalus annulatus. Candidate protective antigens were selected for vaccination experiments based on the effect of gene knockdown on tick mortality, feeding, and fertility. Two cDNA clones encoding for UBQ and SUB were used for cattle vaccination and infestation with R. microplus and R. annulatus. Control groups were immunized with recombinant Bm86 or adjuvant/saline. The highest vaccine efficacy for the control of tick infestations was obtained for Bm86. Although with low immunogenic response, the results with the SUB vaccine encourage further investigations on the use of recombinant subolesin alone or in combination with other antigens for the control of cattle tick infestations. The UBQ peptide showed low immunogenicity, and the results of the vaccination trial were inconclusive to assess the protective efficacy of this antigen. These experiments showed that RNAi could be used for the selection of candidate tick-protective antigens. However, vaccination trials are necessary to evaluate the effect of recombinant antigens in the control of tick infestations, a process that requires efficient recombinant protein production and formulation systems

Observational study of hypertension in Matelica, Italy (Matelica hypertension study)

This study summarizes the results of an epidemiological investigation carried out on the occasion of the Second World Hypertension Day (May 13, 2006) in the city of Matelica in the Region of the Marches, Central Italy. In all, 518 subjects (298 males, average age 52.3 years; 220 females, average age 55 years) with either diagnosed hypertension or who were thought to be normotensive had arterial blood pressure measured. Other cardiovascular risk factors and the costs of pharmacological treatment for hypertension were assessed as well. In 72.46% of examined subjects, arterial blood pressure levels averaged > or =140-90 mmHg if non-diabetic and > or =130-80 mmHg if diabetics. A total of 48.14% of individuals assumed in anamnesis to be normotensive had arterial blood pressure levels higher than the above values and were therefore found to have hypertensive values. The cost of anti-hypertensive treatment in the area of Matelica averages Euro 543.7/patient/year. The present data, which are in line with those of other epidemiological studies performed in Italy, confirm the view that arterial hypertension control in Italy is still largely unsatisfactory. This observation should stimulate both health and specific medical measures to counter the risk of complications of arterial hypertension in aged populations, such as those present in the territory examined
