Posttraumatic stress disorder among earthquake survivors of the Wenchuan area (Sichuan, China)
2014
Background : On May 12, 2008, an earthquake with a power of 8.0 M on the Richter scale occurred in the Wenchuan County of Sichuan Province in southwest China, which was unprecedented in magnitude and aftermath. Approximately 70,000 people were killed and nearly 20,000 went missing. The earthquake caused a wide number of mental and physical health outcomes among survivors, and posttraumatic stress disorder (PTSD) was one of the most commonly studied. Methods : We conducted a systematic overview to assess research achievements about PTSD in the past 6 years after the Wenchuan earthquake, including symptoms and risk factors about PTSD among Wenchuan earthquake survivors, as well as research de…
The Urban Built Environment, Walking and Mental Health Outcomes Among Older Adults: A Pilot Study
2020
The benefits of walking in older age include improved cognitive health (e.g., mental alertness, improved memory functioning) and a reduced risk of stress, depression and dementia. However, research capturing the benefits of walking among older people in real-time as they navigate their world is currently very limited. This study explores cognitive health and well-being outcomes in older people as they walk in their local neighborhood environment. Residents from an independent living facility for older people (mean age 65, n = 11) walked from their home in two dichotomous settings, selected on the basis of significantly different infrastructure, varying levels of noise, traffic and percentag…
Pressure inactivation kinetics of Enterobacter sakazakii in infant formula milk
2007
Survival curves of Enterobacter sakazakii inactivated by high hydrostatic pressure were obtained at four pressure levels (250, 300, 350, and 400 MPa), at temperatures below 30 degrees C, in buffered peptone water (BPW; 0.3%, wt/vol) and infant formula milk (IFM; 16%, wt/vol). A linear model and four nonlinear models (Weibull, log-logistic, modified Gompertz, and Baranyi) were fitted to the data, and the performances of the models were compared. The linear regression model for the survival curves in BPW and IFM at 250 MPa has fitted regression coefficient (R2) values of 0.940 to 0.700, respectively, and root mean square errors (RMSEs) of 0.770 to 0.370. For the other pressure levels, the lin…
The Risk Society: Towards a new modernity
2009
The present review discusses one of the pioneer projects authored by Ulrich Beck, regarding risk perception issues, which was originally titled Risikogesellshaft, Auf dem weg in eine andere Moderne or in English The society of risk, towards a new modernity. This review is part of a broader project related to a Social Psychology doctoral thesis on fears of travelling in urban circumstances.
Patient outcomes in two steroid-free regimens using tacrolimus monotherapy after daclizumab induction and tacrolimus with mycophenolate mofetil in li…
2008
Introduction. Long-term steroid administration may predispose liver transplant recipients to infectious and metabolic complication. Maintaining effective immunoprophylaxis while minimizing the negative consequences of steroid therapy could be a key factor in improving clinical outcomes.Methods. Six hundred two patients were randomized to receive tacrolimus (TAC) immunosuppression with a single-steroid bolus and two doses of daclizumab (DAC) or mycophenolate mofetil (MMF).Results. The incidence of biopsy-proven acute rejection was 19.7% in the TAC/DAC group and 16.2% in the TAC/ MMF group (ns). Three-month patient and graft survival were similar. Steroid use at month-3 was low at 5.5% in the…
Food Processing and Foodborne Illness
2015
Food processing means manipulation of raw materials from plants or animals into food. Since agriculture and animal husbandry were established postharvest procedures were necessary to preserve for a longer time the increasing food supplies coming from the fields and domesticated animals. Food is one of the best culture medium for a lot of microorganisms and preventing food spoilage caused by enzymes and microorganisms is crucial. Deterioration of food is caused mainly by three natural processes: 1. Oxidation – vegetables after harvesting or meat after animal slaughtering get in contact with the oxygen in the air that makes them rancid and unpleasant. 2. Enzyme action – all food contains natu…
Development of a green fluorescent tagged strain of Aspergillus carbonarius to monitor fungal colonization in grapes.
2011
An enhanced green fluorescent protein has been used to tag an OTA-producing strain of Aspergillus carbonarius (W04-40) isolated from naturally infected grape berries. Transformation of the fungus was mediated by Agrobacterium tumefaciens. The most efficient transformation occurred when the co-cultivation was done with 104 conidia due to higher frequency of resistance colonies (894 per 104 conidia) and lower background obtained. To confirm the presence of the hph gene in hygromycin resistant colonies, 20 putative transformants were screened by PCR analysis. The hph gene was identified in all the transformants. Variation on the expression levels of the eGFP was detected among the transformant…
Highly sensitive monoclonal antibody-based immunoassays for the analysis of fluopyram in food samples
2019
Monoclonal antibody-based techniques have become a useful analytical technology in the agro-food sector. Nowadays, residues of the recently registered fungicide fluopyram are increasingly being found in quality control programs. In the present study, novel chemical derivatives of this pesticide were prepared and specific and high-affinity monoclonal antibodies to fluopyram were raised for the first time. Moreover, immunoassays to fluopyram were developed in two alternative enzyme-linked immunosorbent assay formats, using homologous and heterologous assay conjugates, with limits of detection below 0.05 µg L−1. The optimized immunoassays were applied to the analysis of fluopyram in fortified …

A survey to evaluate safety in protected crops in western Sicily
2017
Protected crops in the Mediterranean area has reached advanced production systems, but they should solve environmental, energy and money problems. The greenhouse, in fact, is a system characterized by high energy inputs with a reduced environmental sustainability compared to extensive farming and intensive open field. In Sicily, the area dedicated to annual greenhouse cultivation is 8,200 ha with a total number of farms greater than 6,000; although the sector is of great importance in the Sicilian economy, issues as workplace, food and environmental safety are often overlooked. A survey was carried out with the aim of identifying the possibilities to improve environmental, work and food saf…
