A morphological and mitochondrial assessment of Apis mellifera from Palermo, Italy
1998
A characterization of the honey bees from western Sicily (Palermo, Italy) is presented. Mor- phological comparisons to A. m. ligustica were made using data taken from honey bee populations from southeastern (Bari) and central (Emilia Romagna) Italy. The honey bees of the Palermo area have distinct morphological differences compared to the mainland honey bees. The mtDNA haplotype common in subspecies within the African lineage of A. mellifera predominated in the Sicilian honey bee samples (13 out of 16). These results suggest both the potential and the desirability to expend efforts to conserve A. m. sicula. © Inra/DIB/AGIB/Elsevier, Paris
Computer-assisted sperm analysis and reproductive science; a gift for understanding gamete biology from multidisciplinary perspectives
2018
The science of reproductive biology has been a source of fascination for centuries and has been marked both by important landmarks of discovery and influential, but persistent, errors of fact. The first century physician and philosopher, Galen of Pergamum, carried out empirical investigations on both humans and animals and proposed that conception required a combination of both male and female ‘principles’…
Long Term Culture of the A549 Cancer Cell Line Promotes Multilamellar Body Formation and Differentiation towards an Alveolar Type II Pneumocyte Pheno…
2016
Pulmonary research requires models that represent the physiology of alveolar epithelium but concerns with reproducibility, consistency and the technical and ethical challenges of using primary or stem cells has resulted in widespread use of continuous cancer or other immortalized cell lines. The A549 'alveolar' cell line has been available for over four decades but there is an inconsistent view as to its suitability as an appropriate model for primary alveolar type II (ATII) cells. Since most work with A549 cells involves short term culture of proliferating cells, we postulated that culture conditions that reduced proliferation of the cancer cells would promote a more differentiated ATII ce…

A prospective study of food variety seeking in childhood, adolescence and early adult life
2005
Publication Inra prise en compte dans l'analyse bibliométrique des publications scientifiques mondiales sur les Fruits, les Légumes et la Pomme de terre. Période 2000-2012. http://prodinra.inra.fr/record/256699; International audience; This prospective study of food variety seeking among children was conducted between 1982 and 1999, with a follow-up in 2001–2002. Two- to three-year-old children were given a free choice of lunch foods in a nursery canteen. Their food choices were recorded and used to calculate early variety seeking scores, globally and by food group (vegetables, animal products, dairy products, starchy foods and combined dishes). The same subjects (n=339) were contacted in 2…
PRELIMINARY DATA ON HYDROLYTIC ACTIVITY OF LACTIC ACID BACTERIA ON ß-LACTOGLOBULIN IN MILK
2014
β-Lactoglobulin (β-lg) is the major whey milk protein and it represents the main allergen in cow and sheep milk (1). Microbial fermentation produces some proteolytic enzymes and leads to the degradation of milk protein allergens. In this study, the results of a screening on the ability of lactic acid bacteria (LAB) isolated from typical Sicilian cheeses to reduce the β-lg are shown. This screening was carried out through an indirect competitive ELISA. The lactic acid fermentation was found to be suitable for decreasing milk immunoreactivity. Twenty three strains of cheese LAB, belonging to six genera (Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Pediococcus and Streptococcus), wer…
Mesophilic and thermophilic anaerobic co-digestion of rendering plant and slaughterhouse wastes.
2011
Co-digestion of rendering and slaughterhouse wastes was studied in laboratory scale semi-continuously fed continuously stirred tank reactors (CSTRs) at 35 and 55 °C. All in all, 10 different rendering plant and slaughterhouse waste fractions were characterised showing high contents of lipids and proteins, and methane potentials of 262-572 dm(3)CH(4)/kg volatile solids(VS)(added). In mesophilic CSTR methane yields of ca 720 dm(3) CH(4)/kg VS(fed) were obtained with organic loading rates (OLR) of 1.0 and 1.5 kg VS/m(3) d, and hydraulic retention time (HRT) of 50 d. For thermophilic process, the lowest studied OLR of 1.5 kg VS/m(3) d, turned to be unstable after operation of 1.5 HRT, due to ac…
Co-digestion of sewage sludge and sterilized solid slaughterhouse waste: Methane production efficiency and process limitations
2012
The rendering product of Category 2 and 3 Animal By-Products is known as sterilized mass (SM) and it is mainly composed of fat and proteins, making it interesting substrate for anaerobic digestion. Batch and semi-continuous laboratory experiments were carried out to investigate the effect of SM addition in co-digestion with sewage sludge on methane production and possible process limitations. Results showed that SM addition in the feed mixture up to 5% (w/w), corresponding to 68.1% of the organic loading, increased methane production 5.7 times, without any indication of process inhibition. Further increase of SM addition at 7.5% (w/w) caused methane production decrease and volatile solids r…
Methane potential of sterilized solid slaughterhouse wastes.
2012
Abstract The aim of the current study was to determine chemical composition and methane potential of Category 2 and 3 solid slaughterhouse wastes rendering products (SSHWRP) viz. melt, decanter sludge, meat and bone meal (MBM), technical fat and flotation sludge from wastewater treatment. Chemical analyses showed that SSHWRP were high in protein and lipids with total solids (TS) content of 96–99%. Methane yields of the SSHWRP were between 390 and 978 m3 CH4/t volatile solids (VS)added. Based on batch experiments, anaerobic digestion of SSHWRP from the dry rendering process could recover 4.6 times more primary energy than the energy required for the rendering process. Estonia has technologic…
Jugement de la couleur des carcasses en abattoir. Eléments d’objectivation de la notation experte de la couleur des viandes de gros bovins Charolais
2016
Evaluation of carcass color at the slaughterhouse Expert notation is the reference method for the evaluation of bovine meat color, notably for quality. A total of 140 Charolais carcasses were scored at the slaughterhouse on a color scale going from 1 (too light) to 5 (too dark). These expert scores were compared to three types of instrumental data (L*a*b / RVB referential; image shooting with image processing / chromameter). Amongst the instrumental measurements, the values obtained after image processing of the whole muscle seems to be better associated with the scores obtained for color by experts than the scores obtained with the chromameter for which the zone of the muscle analyzed is m…
