Long-term survival of pathogenic and sanitation indicator bacteria in experimental biowaste composts
2005
ABSTRACT For economic, agricultural, and environmental reasons, composting is frequently used for organic waste recycling. One approach to limiting the potential risk from bacterial food-borne illnesses is to ensure that soil amendments and organic fertilizers are disinfected. However, more knowledge concerning the microbiological safety of composted substrates other than sludge and manure is necessary. Experimental in-vessel biowaste composts were used to study the survival of seeded Listeria monocytogenes , Salmonella enterica subsp. enterica serotype Enteritidis, and Escherichia coli . Four organic waste mixtures, containing various proportions of paper and cardboard, fruits and vegetabl…

PLLA biodegradable scaffolds for angiogenesis via Diffusion Induced Phase Separation (DIPS)
2008
A critical obstacle in tissue engineering is the inability to maintain large masses of living cells upon transfer from the in vitro culture conditions into the host in vivo. Capillaries, and the vascular system, are required to supply essential nutrients, including oxygen, remove waste products and provide a biochemical communication “highway”. For this reason it is mandatory to manufacture an implantable structure where the process of vessel formation – the angiogenesis – can take place. In this work PLLA scaffolds for vascular tissue engineering were produced by dip-coating via Diffusion Induced Phase Separation (DIPS) technique. The scaffolds, with a vessel-like shape, were obtained by p…
A COMPOSITE PLLA SCAFFOLD FOR REGENERATION OF COMPLEX TISSUES
2010
A composite biodegradable scaffold incorporating an integrated network of synthetic blood vessels was designed and prepared, in line with the requirements of a scaffold effectively supporting the regeneration of highly vascularized tissues. In other words, this composite scaffold should allow the regeneration of complex injured tissue (e.g. dermis) and, at the same time, favour the development of a vascular network on its inner, i.e. a 3D polymeric scaffolds embedding synthetic blood vessel-like structures for nutrient supply and metabolite removal. PLLA assures a high degree of biocompatibility and a low level of inflammation response upon implantation, while the embedded tubular vessel-li…
Efectos de un programa de intervención (PHS) para la mejora de los hábitos saludables en la primera adolescencia
2015
Background: it is vital to monitor and promote healthy lifestyle habits in early adolescence, as it is a time of changes when future lifestyle habits are formed. Methods: a study was conducted to find out the effects of a Healthy Habits Program (HHP) in children between the ages of 10 and 12 years (N = 158). The study included an intervention group (IG) (n = 90), which participated in the HHP for 8 months, and a control group (CG) (n = 100). In order to assess healthy habits in these children we used the Inventory of Healthy Habits (IHH), the reliability of which was previously evaluated (N = 134). Results: the IHH obtained good reliability, Interclass Correlation Coefficient (range .506 - …

Temporal Series Analysis on Avoidable Mortality for the Assessment of an Intervention Program in a Hospital
2017
Background: Avoidable mortality (AM) is one of the most important health indicators (HI) and represents the quality of care in a hospital.Objective: This study measured the efficacy of a training program for a hospital healthcare staff to reduce AM.Methods: This epidemiological study on community intervention analyzed time-series data on HI by semesters from 2008 to 2015. The pre-intervention phase was examined from January 2008 to December 2014; the intervention phase was investigated in the first semester of 2015; and the post-intervention phase was examined in the second semester of 2015.Results: Resindicate a series with a rising tendency until the 14th semester and a pronounced descent…
Tracking multiple pathways of waste from a northern bluefin tuna farm in a marine-coastal area.
2011
Aquaculture of bluefin tuna in Mediterranean coastal waters has generated growing concern about the negative environmental effects. In the present isotopic study we examined the dispersal and fate of organic matter derived from a Mediterranean tuna farm in the surrounding environment. An overall enrichment in the heavy nitrogen isotope was found in the feed and in farmed tunas, indicating the input of isotopically traceable organic matter in the system. Waste was clearly traceable in the water column up to 1000 m from the cages, while only slight accumulation occurred in the sediment just below the cages. Waste was isotopically shown also to contribute to the diet of demersal and benthopela…
