Effect of replacing sucrose with tagatose and isomaltulose in Mandarin orange marmalade on rheology, colour, antioxidant activity, and sensory properties

The aim of this study was to make mandarin orange marmalades, in which sucrose is replaced by sweeteners, such as tagatose and isomaltulose, which are non-cariogenic and have a low glycemic index. Analyses of rheology, colour, antioxidant activity, microbiology, and sensory properties were carried out on marmalades on their first day, and after 90, 180, and 360 days of storage. The results showed that marmalades made with healthy sweeteners had a less elastic character and were thinner in consistency than those made with sucrose. Lightness was shown to be highest in mandarin orange marmalades made with tagatose, although colour was stable for 180 days to one year of storage. Tagatose also enhanced the antioxidant activity of these marmalades. All marmalades were microbiologically stable. Finally, marmalades made with tagatose alone scored the highest for global acceptance and intention of buying by consumers

Prevention through design: The effect of European Directives on construction workplace accidents

Workplace accidents still occur with distressing frequency, particularly in construction. Industrialized countries have become increasingly aware of this situation and have adopted policies to attempt to deal with this issue. Such policies have led to the development of new laws and regulations with a view to improving workplace conditions. This paper first analyzes policies regarding accident prevention in the European Union, as initially stipulated in the European Framework Directive 89/391/EEC, and more specifically in Directive 92/57/EEC, on the implementation of minimum safety and health requirements at temporary or mobile construction sites, concentrating on prevention through design. Whilst designers previously had some responsibilities for reducing risk under common law provisions in many countries, this directive was the first explicit legislation to enforce particular duties upon them. The adaptation of the provisions in this directive to the national legislation of EU member countries is also studied. The second section of the paper analyzes the incidence rate of workplace accidents in the construction sector in each country from the year when these regulations came into force until the present time. Based on the evolution of these accident rates, the paper postulates the extent to which European policies have contributed to accident prevention in construction. It is now more than a decade since this legislation has been in force which provides a suitable period for a reflective analysis on it is impact

The impact of occupational health and safety regulations on prevention through design in construction projects: perspectives from Spain and the United Kingdom

BACKGROUND: Since the mid-1990s, Prevention through Design (PtD) has become increasingly prevalent in the built environment. The acceptance of PtD has largely been due to the removal or reduction of risks during the execution phase of construction projects. European States have had the added impetus of national legislation. OBJECTIVE: This paper analyzes the influence of European Union Directive 92/57/EEC on occupational safety and health injury prevention in the project design phase. METHODS: Qualitative methods comprised individual semi-structured interviews and focus groups with a panel of experts. Sixty individuals from construction and related professions (architects, engineers, constructors, developers, and other construction experts) answered 17 key questions to establish national perceptions of the effectiveness of Directive 92/57/EEC in Spain and the United Kingdom (UK). RESULTS: The implementation of PtD in the project design phase in the UK is clearer since the regulations explicitly state the obligations of project designers as well as those of the coordinator. Interviews with Spanish experts show that, in Spain, the prevention culture is less frequently realized. CONCLUSIONS: The most significant differences between the European Directive and national regulations which influence PtD are linked to the Health and Safety Coordinator, and Health and Safety documents

p53 Aberrations do not predict individual response to fludarabine in patients with B-cell chronic lymphocytic leukaemia in advanced stages Rai III/IV

Abnormalities of p53 have been associated with short survival and non-response to therapy in chronic lymphocytic leukaemia (CLL). We have evaluated the rate of response to fludarabine as first-line therapy in 54 patients with advanced stage CLL, analysing the cytogenetic profile, aberrations in p53, including the methylation status of its promoter, and the immunoglobulin heavy-chain variable-region (IGVH) mutation status. According to the advanced stage of the disease in this series, 75% of patients presented genetic aberrations associated with poor prognosis: del(17p) and/or del(11q), and no-mutated IGVH genes. Ten patients (18.5%) had methylation in the promoter region of p53. Eighty-three per cent of patients treated achieved a response, with a high rate of complete remission (47.6%). Although we found a significant correlation between failures and the presence of p53 aberrations (P = 0.0065), either with methylation (P = 0.018) or deletion (P = 0.015), 64% of the patients with aberrations in this gene responded to treatment (11/17), suggesting that fludarabine induces high remission rates, even in these patients. This is the first time that the significance of p53 promoter methylation status is described in this pathology, and our data support that this epigenetic phenomenon could be involved in the pathogenesis and clinical evolution of CLL

Shapes of the 192,190^{192,190}Pb ground states from beta decay studies using the total absorption technique

The beta decay of $^{192,190}$Pb has been studied using the total absorption technique at the ISOLDE(CERN) facility. The beta-decay strength deduced from the measurements, combined with QRPA theoretical calculations, allow us to infer that the ground states of the $^{192,190}$Pb isotopes are spherical. These results represent the first application of the shape determination method using the total absorption technique for heavy nuclei and in a region where there is considerable interest in nuclear shapes and shape effects

Update on the effects of antioxidants on diabetic retinopathy : In vitro experiments, animal studies and clinical trials

Current therapies for diabetic retinopathy (DR) incorporate blood glucose and blood pressure control, vitrectomy, photocoagulation, and intravitreal injections of anti-vascular endothelial growth factors or corticosteroids. Nonetheless, these techniques have not been demonstrated to completely stop the evolution of this disorder. The pathophysiology of DR is not fully known, but there is more and more evidence indicating that oxidative stress is an important mechanism in the progression of DR. In this sense, antioxidants have been suggested as a possible therapy to reduce the complications of DR. In this review we aim to assemble updated information in relation to in vitro experiments, animal studies and clinical trials dealing with the effect of the antioxidants on DR

Self-care practices of primary health care patients diagnosed with chronic heart failure : A cross-sectional survey

Funding: This study was granted by the Official College of Nurses of Barcelona (Spain) (PR-2079 /15)Chronic heart failure patients require self-care behaviors and active monitoring of signs and symptoms to prevent worsening. Most patients with this condition are attended in primary healthcare centers. This study aimed to evaluate the endorsement of and adherence to self-care behaviors in primary health care patients with chronic heart failure. We conducted a multicenter cross-sectional study. We randomly included chronic heart failure patients from 10 primary healthcare centers in the Barcelona metropolitan area (Spain). Patients completed the European Heart Failure Self-Care Behaviour Scale, a health literacy questionnaire. Differences between groups were studied using ANOVA tests. We included 318 patients with a mean age of 77.9 years, mild limitations in functional activity New York Heart Association scale (NYHA) II = 51.25%), and a low health literacy index of 79.6%. The endorsement of self-care behaviors was low in daily weighing (10.66%), contacting clinicians if the body weight increased (22.57%), and doing physical exercise regularly (35.58%). Patients with lower educational levels and a worse health literacy had a lower endorsement. The screening of individual self-care practices in heart failure patients might improve the clinician follow-up. We suggest that primary healthcare clinicians should routinely screen self-care behaviors to identify patients requiring a closer follow-up and to design and adapt rehabilitation programs to improve self-care

Factors structuring microbial communities in highly impacted coastal marine sediments (Mar Menor lagoon, SE Spain)

Coastal marine lagoons are environments highly vulnerable to anthropogenic pressures such as agriculture nutrient loading or runoff from metalliferous mining. Sediment microorganisms, which are key components in the biogeochemical cycles, can help attenuate these impacts by accumulating nutrients and pollutants. The Mar Menor, located in the southeast of Spain, is an example of a coastal lagoon strongly altered by anthropic pressures, but the microbial community inhabiting its sediments remains unknown. Here, we describe the sediment prokaryotic communities along a wide range of environmental conditions in the lagoon, revealing that microbial communities were highly heterogeneous among stations, although a core microbiome was detected. The microbiota was dominated by Delta- and Gammaproteobacteria and members of the Bacteroidia class. Additionally, several uncultured groups such as Asgardarchaeota were detected in relatively high proportions. Sediment texture, the presence of Caulerpa or Cymodocea, depth, and geographic location were among the most important factors structuring microbial assemblages. Furthermore, microbial communities in the stations with the highest concentrations of potentially toxic elements (Fe, Pb, As, Zn, and Cd) were less stable than those in the non-contaminated stations. This finding suggests that bacteria colonizing heavily contaminated stations are specialists sensitive to change
