The combined impact of cold smoking and natural antioxidants on quality and shelf life of dolphinfish (Coryphaena hippurus) fillets

2019

This study aimed to produce new value-added products from dolphinfish (Coryphaena hippurus) as fillets when using cold smoking combined with natural antioxidants, obtained from Halocnemum strobilaceum a plant belonging to halophytes. The fillet treatments were controlled (untreated), immersed in standard brine (STD), treated with NaCI and antioxidant before freezing (Aox-pre) and treated with NaCl and antioxidant after thawing (Aox-post). The quality of dolphinfish fillets was assessed using sensory, biochemical, microbiological, and technological parameters. Treating fillets with antioxidants before freezing and cold smoking (Aox-pre) enhanced significantly the shelf life, as well as impro…

Antibacterial PEGylated Solid Lipid Microparticles for Cosmeceutical Purpose: Formulation, Characterization, and Efficacy Evaluation

2020

The development of efficacious means of delivering antioxidant polyphenols from natural sources for the treatment of skin diseases is of great interest for many cosmetic and pharmaceutical companies. Resveratrol (RSV) and Limonene (LIM) have been shown to possess good anti-inflammatory and antibacterial properties against Staphylococcus aureus infections responsible for many skin disorders, such as acne vulgaris. In this study, solid lipid microparticles are designed as composite vehicles capable of encapsulating a high amount of trans-RSV and enhancing its absorption through the stratum corneum. A microparticulate system based on mixture of PEGylate lipids, long-chain alcohols and LIM is a…

B1 Was the Ancestor B Chromosome Variant in the Western Mediterranean Area in the Grasshopper Eyprepocnemis plorans.

2014

We analyzed the distribution of 2 repetitive DNAs, i.e. ribosomal DNA (rDNA) and a satellite DNA (satDNA), on the B chromosomes found in 17 natural populations of the grasshopper Eyprepocnemis plorans plorans sampled around the western Mediterranean region, including the Iberian Peninsula, Balearic Islands, Sicily, and Tunisia. Based on the amount of these repetitive DNAs, 4 types of B variants were found: B 1 , showing an equal or higher amount of rDNA than satDNA, and 3 other variants, B 2 , B 24 and B 5 , bearing a higher amount of satDNA than rDNA. The variants B 1 and B 2 varied in size among populations: B 1 was about half the size of the X chromosome in Balearic Islands, but two-thir…

Importance of Propionibacterium acnes hemolytic activity in human intervertebral discs: A microbiological study

2018

Most patients with chronic lower back pain (CLBP) exhibit degenerative disc disease. Disc specimens obtained during initial therapeutic discectomies are often infected/colonized with Propionibacterium acnes, a Gram-positive commensal of the human skin. Although pain associated with infection is typically ascribed to the body's inflammatory response, the Gram-positive bacterium Staphylococcus aureus was recently observed to directly activate nociceptors by secreting pore-forming α-hemolysins that disrupt neuronal cell membranes. The hemolytic activity of P. acnes in cultured disc specimens obtained during routine therapeutic discectomies was assessed through incubation on sheep-blood agar. T…

Phylogeny of Salicornioideae (Chenopodiaceae): Diversification, biogeography, and evolutionary trends in leaf and flower morphology

2006

Chenopodiaceae-Salicomioideae (14-16 gen./c. 90 spp.) are distributed worldwide in coastal and inland saline habitats. Most of them are easy to recognize by their succulent-articulated stem with strongly reduced leaves and by flowers aggregated in dense, thick spike-shaped thyrses. ITS and the atpB-rbcL spacer were sequenced for 67 species representing 14 genera of Salicomioideae and analysed with maximum parsimony and maximum likelihood, a fossil-calibrated molecular clock using the penalized likelihood method, and lineage through time plots. The evolution of stem, leaf, and flower morphology was traced using MacClade. Both molecular markers indicate that the monophyletic Salicomioideae or…

Histological evaluation of bone repair using beta-Tricalcium Phosphate

2010

Objectives: The aim of the present study was to evaluate bone repair in defects induced in the cranium of Wistar rats using ?-tricalcium phosphate. Study Design: In this research, we used 30 rats, randomly distributed in three groups of 10 animals (G1, G2 and G3), corresponding respectively to time of histological evaluation (7, 15 and 30 days). This was a paired study, a defect being induced in the parietal bone on either side of the median sagittal suture of the animals, being the left-hand side the experimental subgroup (filled by biomaterial) and the right control. The histological evaluation was performed by means of light microscopy. The collected data were submitted to the Fisher Exa…

The Impact of Environmental Conditions on Efficiency of Host Plant DNA Barcoding for Polyphagous Beetles.

2015

Recently, several papers were published dealing with host plant identification for selected species of insects, including beetles. These studies took advantage of the DNA barcoding approach and generally showed that it is possible to identify diet composition from plant DNA present in insect guts. However, none of these studies considered how the impact of environmental conditions affected the likelihood of insect feeding and, therefore, the presence of host plant DNA that could be amplified and sequenced. In the present study, individuals of the polyphagous weevil Centricnemus leucogrammus (Germar, 1824) (Curculionidae: Entiminae) were used to test the hypothesis that harsh environmental c…

Chloracne after release of TCDD at Seveso, Italy

1981

ABSTRACT The paper deals with clinical and epidemiological findings concerning persons showing skin lesions after release of TCDD at Seveso. A positive association was observed between geographical distribution of cases and levels of soil contamination. Gastro-intestinal tract impairments were more frequently observed in children with chloracne than in children from the same areas showing no skin lesions. To date, no major immunological involvement has been observed in samples of children exposed to TCDD.

La juridicisation de l’activité syndicale durant le Front populaire (CGT, CFTC, CSPF)

2014

National audience; Dans l’histoire du mouvement ouvrier, le Front populaire constitue un tournant puisque les syndicats tendent à s’affirmer en tant que véritables acteurs sociaux grâce à une représentativité nouvellement acquise dans le cadre d’une expérience unique d’un syndicalisme de masse. La signature des accords Matignon et les différentes dispositions juridiques qui suivent - loi sur la conciliation et l’arbitrage du 31 décembre 1936 et création de la Cour supérieure d’arbitrage en 1938 - ouvrent un chantier considérable en termes de droit du travail qui nécessite un investissement important des militants syndicaux désormais impliqués dans des procédures nouvelles (délégués-ouvriers…
