Recent aflatoxin survey data in milk and milk products: A review

2017

Aflatoxin M1 (AFM1) occurrence in human and animal milk, infant formula, powdered milk, cheese and yoghurt represents a risk for health. The last four years (2010–2014) of data, as well as the most frequently and updated analytical methods applied for AFM1 quantification, are evaluated. Aflatoxin B1, considered the most potent toxic aflatoxin, is metabolised to form the monohydroxy derivative AFM1. This metabolized, expressed in the milk, is relatively stable, and it is not eliminated by heat treatments or pasteurisation, and thus represents a serious health concern.

Presence of mycotoxin in commercial infant formulas and baby foods from Italian market

2014

In this study a total of 75 commercially Italian samples of baby foods, including 13 infant formula milks (infant formula powders, ready-to-use preparation), 11 dairy products (cheese and yogurt), 25 cereal-based baby foods, 16 fruit and vegetables compotes, and 10 fruit and vegetables purees (composed of pear, peach, banana and for apple), were analyzed to provide an overview on mycotoxin presence. The presence was carried out by evaluating of 23 mycotoxins: ochratoxin-A (OTA), patulin (PAT), two aflatoxins (AFM1, AFB1), three zearalenones (ZONs), which include zearalenone (ZON) and its metabolites (α-zearalenol (α-ZOL) and β-zearalenol (β-ZOL)), nine trichothecenes: deoxynivalenol (DON), …

Le mode de financement et l'efficacité de la formation initiale des enseignants du primaire en Tunisie

1999

Actes des XIXè journées de l'AES; International audience; Depuis la réforme de 1991, la formation initiale des enseignants du primaire en Tunisie dure deux années au cours desquelles les élèves-enseignants sont astreints à un régime d'internat. Le financement de la formation des maîtres est assuré par les fonds publics, d'importantes aides sont octroyées aux élèves-enseignants. Leurs performances pédagogiques sont satisfaisantes, mais l'insertion des diplômés commence à être plus difficile.

Aggolomeration and New Firm Formation. Evidence from Italy

2013

Hedgehog signaling and primary cilia are required for the formation of adult neural stem cells.

2008

Neural stem cells that continue to produce neurons are retained in the adult hippocampal dentate gyrus. The mechanisms by which embryonic neural progenitors expand and transform into postnatal neural stem cells, an essential process for the continual production of neurons throughout life, remain unknown. We found that radial astrocytes, the postnatal progenitors in the dentate gyrus, failed to develop after embryonic ablation of ciliary genes or Smoothened (Smo), an essential component for Sonic hedgehog (Shh) signaling. Postnatal dentate neurogenesis failed in these mutant mice, and the dentate gyrus became severely hypotrophic. In contrast, expression of a constitutively active Smo (SmoM2…

Glutamate Activates Phospholipase D in Hippocampal Slices of Newborn and Adult Rats

1993

Phospholipase D (PLD) is activated by many neurotransmitters in a novel signal transduction pathway. In the present work, PLD activity was studied comparatively in hippocampal slices of newborn and adult rats. Basal PLD activity in adult rats was almost three times higher than in newborn rats. In newborn rats, L-glutamate and 1S,3R-1-aminocyclopentane-1,3-dicarboxylic acid (1S,3R-ACPD) time- and concentration-dependently enhanced the formation of [3H]phosphatidylpropanol ([3H]PP) and of [3H]phosphatidic acid in the presence of 2% propanol. N-Methyl-D-aspartate and kainate (both 1 mM) caused small, but significant increases (approximately 50%), whereas alpha-amino-3-hydroxy-5-methylisoxazole…

Why use long acting bronchodilators in chronic obstructive lung diseases? An extensive review on formoterol and salmeterol

2015

Abstract Long-acting β 2 -adrenoceptor agonists, formoterol and salmeterol, represent a milestone in the treatments of chronic obstructive lung diseases. Although no specific indications concerning the choice of one molecule rather than another are provided by asthma and COPD guidelines, they present different pharmacological properties resulting in distinct clinical employment possibilities. In particular, salmeterol has a low intrinsic efficacy working as a partial receptor agonist, while formoterol is a full agonist with high intrinsic efficacy. From a clinical perspective, in the presence of low β 2 -adrenoceptors availability, like in inflamed airways, a full agonist can maintain its b…
