High Pressure Processing Impact on Alternariol and Aflatoxins of Grape Juice and Fruit Juice-Milk Based Beverages.

2021

High-pressure processing (HPP) has emerged over the last 2 decades as a good alternative to traditional thermal treatment for food safety and shelf-life extension, supplying foods with similar characteristics to those of fresh products. Currently, HPP has also been proposed as a useful tool to reduce food contaminants, such as pesticides and mycotoxins. The aim of the present study is to explore the effect of HPP technology at 600 MPa during 5 min at room temperature on alternariol (AOH) and aflatoxin B1 (AFB1) mycotoxins reduction in different juice models. The effect of HPP has also been compared with a thermal treatment performed at 90 °C during 21 s. For this, different juice models, or…

Limited survey for the occurrence of aflatoxins in cereals and poultry feeds from Rabat, Morocco

2007

Fifty eight (58) samples of cereals for human consumption (20 corn flour, 17 wheat flour) and poultry feeds (n=21) purchased from popular markets of Rabat in Morocco were analyzed for aflatoxins (AF) by HPLC with immunoaffinity column (IAC) clean-up and fluorimetric detection. The incidence of AF in corn, wheat flour and poultry feeds was about 80, 17.6 and 66.6% respectively. High contamination levels were found in corn and poultry feeds samples. Levels of contamination of analyzed samples with AFB1 ranged from 0.23 to 11.2, 0.03 to 0.15 and 0.05 to 5.38 ng/g for corn, wheat and poultry feeds respectively. Results showed also that the contamination of 10% of samples of corn was higher than…

Aspetti tipo-cronologici e archeometrici delle ceramiche africane nel territorio di Cignana (Naro, AG, Sicilia)

2020

Il progetto di ricerca, condotto in cotutela tra l'Università di Palermo e Aix-Marseille Université, si basa sullo studio delle ceramiche africane importate in Sicilia tra la fine del I e il VII secolo d.C.. La ricerca si basa sui frammenti - tutte le classi incluse - raccolti dal gruppo di ricerca di Palermo durante le ricognizioni archeologiche nei dintorni della villa romana di Cignana (Agrigento) e nell'entroterra di Termini Imerese (Palermo). L'approccio multidisciplinare archeologico ed archeometrico, condotto in collaborazione con diversi specialisti di queste discipline, ha permesso di definire l'origine delle diverse produzioni e di riflettere sulla loro circolazione in Sicilia, in…

A method for screening diacetyl and acetoin-producing bacteria on agar plates

1994

A simple method for screening bacteria for diacetyl and acetoin production was developed. This method is based on the ability of diacetyl and acetoin to form a red insoluble complex with α-naphthol in the presence of creatine. Addition of carboxymethyl-cellulose containing calcium citrate in the medium allowed discrimination between citrate utilizing and non-utilizing bacteria.

Extraprostatic Spindle Cell Stromal Tumor of the Prostate: Case Report

2007

Several benign and malignant nonepithelial and stromal-like lesions arise in the prostate. Because such lesions are rare, their recognition is essential, because treatment and prognosis depend on an adequate pathohistologic classification. We report a case of an 83-year-old man with a stromal tumor of the prostate of uncertain malignant potential (STUMP). He presented with urinary retention and rectal constipation. On bimanual examination, a rectally and suprapubically palpable mass was found. Imaging studies revealed a 12 x 8 cm pararectal inhomogeneous mass of uncertain origin compressing rectum and urethra. The tumor was resected by a retropubic approach and examined immunohistochemicall…

Atrial Fibrillation Is Associated with a Marker of Endothelial Function and Oxidative Stress in Patients with Acute Myocardial Infarction

2015

International audience; Background Atrial fibrillation (AF), whether silent or symptomatic, is a frequent and severe complication of acute myocardial infarction (AMI). Asymmetric dimethylarginine (ADMA), an endogenous eNOS inhibitor, is a risk factor for endothelial dysfunction. We addressed the relationship between ADMA plasma levels and AF occurrence in AMI.Methods 273 patients hospitalized for AMI were included. Continuous electrocardiographic monitoring (CEM) !48 hours was recorded and ADMA was measured by High Performance Liquid Chromatography on admission blood sample.Results The incidence of silent and symptomatic AF was 39(14%) and 29 (11%), respectively. AF patients were markedly o…
