Degradation of heterocyclic aromatic amines in oil under storage and frying conditions and reduction of their mutagenic potential.
2007
Heterocyclic aromatic amines (HAA) were systematically studied concerning their partition behavior in water/oil-systems and their thermostability in different animal derived fats and vegetable oils. Partitioning of IQx-compounds and PhIP in water/oil systems was found to depend on the polarity defined by the molecular structure and on the pH-value of the aqueous phase. In particular, beta-carbolines norharman and harman showed a significant strong lipophilic character at alkaline pH. After heating in frying fats at 130 degrees C, contents of IQx compounds and PhIP were reduced by more than 40% and after heating at 180 degrees C less than 10% of the HAA initial concentration was recovered. B…
Assessment of Salmonella and Listeria monocytogenes level in ready-to-cook poultry meat: Effect of various high pressure treatments and potassium lac…
2014
International audience; The objective of this study was to develop a probabilistic model in order to determine the contamination level of Salmonella and Listeria monocytogenes in ready-to-cook poultry meat, after a high pressure (HP) treatment. The model included four steps: i) Reception of raw meat materials, mincing and mixing meat, ii) Partitioning and packaging into 200-g modified atmosphere packs, iii) High pressure treatment of the meat, and iv) Storage in chilled conditions until the end of the shelf-life. The model excluded the cooking step and consumption at consumer's home as cooking practices and heating times are highly variable. The initial contamination level of Salmonella and…
Skin cancer screening – better safe than sorry
2020
Skin cancer is the most common type of cancers. In Latvia, on average there are approximately 200 new melanoma and 1300 non-melanoma cancer cases per year. Non-melanoma cancers are: Basal Cell Carcinoma, Squamous Cell Carcinoma and others. It is essential to discover skin cancer at an early stage when it is treatable. For this reason, a reliable, non-invasive and quantitative skin cancer screening method is necessary in order to discover skin cancer as early as possible and to help physicians such as general practitioners and dermatologists assign patients to the best treatment as soon as possible. In this article, the current skin cancer incidence as well as the screening situation in Latv…
Effect of thermal treatments on vitality and physical characteristics of bean, chickpea and lentil
2012
Thermal disinfestation treatments are relatively easy to apply, leave no chemical residues and may have some fungicidal activity. However, temperature and time combinations required to kill insect pests may meet or exceed those that reduce the viability of seeds, nutrients content, shelf life or technological characteristics. The aim of this study was to investigate the effect of thermal treatments (different temperature and time combinations) on physical and biological characteristics of bean, chickpea and lentil. Seed samples of common bean, chickpea and lentil were treated at low (12, 24 or 48 h at −18 °C) or high (30, 60 or 90 min at 60 °C) temperature. Seed germination, mean germinatio…
Grammatica della ricetta, retorica della cucina
2021
Cooking is - precisely - more a practical know-how than a form of theoretical knowledge. Much like swimming, driving a car, riding a bike, talking. All things that you don't learn in books or lessons but by doing them, putting them into practice with assiduity, courage, stubbornness. As long as it is the body itself that acquires the ways, the techniques, the rules. Of course, in the kitchen scientific and technical knowledge, theoretical knowledge, history, culture, traditions also count for a lot. But when it comes to rolling out a pastry, flipping an omelette, kneading a pizza dough (to limit ourselves to very elementary preparations), what counts is manual dexterity, a clinical eye, the…
ANFORE E CERAMICHE COMUNI E DA FUOCO DA THERMAE HIMERAEAE (SICILIA) E DAL SUO HINTERLAND
2014
This report, part of a wider project involving the ancient landscapes of Himera and Thermae, presents the archaeological and archaeometric results on Late Roman amphorae and coarse/cooking wares from Termini Imerese. The aim is also to illustrate the distribution of the same types of Roman pottery in the hinterland of Thermae, where the Dept. of Cultural Heritage of Palermo University has carried out intensive surveys (from 1982, published from 1988 until 2009). A good documentation of African amphorae, coarse/cooking wares, produced both in Byzacena and Zeugitana, and also local amphorae and coarse/cooking wares and Pantellerian ware, have been found both in Thermae and in the hinterland, …
Thermae Himeraeae (Sicilia) e il suo hinterland: dalla documentazione ceramica alle dinamiche del popolamento in età imperiale
2014
This paper presents the archaeological and archaeometric results about roman amphorae, coarse/cooking wares and TSA from Termini Imerese (NW Sicily), and the relationships with distribution of same pottery in the hinterland of ancient city, where in the last thirty years the Dept. of Cultural Heritage of University of Palermo have carried out extensive surveys (San Leonardo, Torto and Northern Imera valleys). The research starts up typological and archaeometric studies published in the nineties of last century, now part of a new interdisciplinary program with CNR-IBAM (Catania) and CNRS (Aix-en-Provence). A good documentation of African amphorae, coarse/cooking wares, produced both in Byzac…
Transarterial chemoembolization and sorafenib in patients with intermediate-stage hepatocellular carcinoma: time to enter routine clinical practice?
2015
According to the guidelines of the European Association for the Study of the Liver (EASL), patients affected from hepatocellular carcinoma (HCC) can be classified according to the Barcelona Clinic Liver Cancer (BCLC) staging system. This classification system divides HCC patients in five stages (0, A, B, C and D) on the basis of a number of prognostic and treatment- related variables such as tumor status and liver function. A specific treat ment approach is then proposed for each of the above-mentioned stages. Transarterial chemoembolization (TACE) is recommended as first-line therapy in the treatment of patients with intermediate-stage (BCLC-B class) HCC [1]. The efficacy of this procedure…
Survival analysis of proposed BCLC-B subgroups in hepatocellular carcinoma patients
2013
Background & Aims The BCLC-staging system is used to facilitate treatment decisions in patients with hepatocellular carcinoma (HCC). Owing to the observed clinical heterogeneity of the intermediate stage BCLC-B, a subclassification was proposed taking Child–Pugh score and extended criteria for transplantation into account. Analysis of the prognostic significance of a proposed subclassification of the BCLC-B score in a European cohort of HCC patients. Methods Eight hundred and eighty four consecutive HCC patients were retrospectively analysed. Patients with stage BCLC-B were grouped according to the proposed subclassification. Baseline patient and tumour characteristics, therapy and overall …
Two large steps forward, one small step back
2018
In 2017, the FDA approved regorafenib and nivolumab for the treatment of patients with hepatocellular carcinoma following prior sorafenib treatment, opening the door for an effective systemic second-line therapy in advanced disease. By contrast, the addition of sorafenib to transarterial chemoembolization with drug-eluting beads did not improve progression-free survival in the intermediate disease stage.
