Abstract
Date palm fruit has been considered for centuries as an ancient nutritional constituent in the human diet. Recently, global trade in dates increased at an average that, simultaneously, will be accompanied by an increase in date palm byproducts. Supported by date phytochemicals and their health benefits, the aim of this work is to evaluate for the first time the presence of special metabolites of plant called phytoprostanes (PhytoPs) in five different varieties of the Phoenix dactylifera L. pulps and pits using a microLC-ESI-QTrap-MS/MS methodology. Results obtained showed the interest of using these matrices as potential sources of several PhytoPs (ent-16-B1-PhytoP; ent-9-L1-PhytoP; and epimers of ent-16-F1t-PhytoP and of 9-F1t-PhytoP). The variation in concentration between different varieties and different DPF parts was also evaluated. Results obtained will help to unravel the biological activities associated with DPF consumption that could be related to these bioactive metabolites.

Abstract
The prevalence of Fasciola hepatica infection in the snail Galba truncatula was studied for the first time in Algeria using Multiplex PCR. A total of 722 individuals were collected from 11 typical habitats (temporary ponds, road ditches and puddles) distributed in five localities of the El Tarf province, known for endemicity of fascioliasis. Snails were divided in 75 groups and DNA extraction was performed using Chelex® (Biorad, Nazareth Eke). Two primers were used, the first is specific for 124 bp DNA fragment of Fasciola sp and the second one represents the ITS-2 lymnaeids sequence (500-600 bp). The prevalence of the infection was estimated to be 46.66% for pools (35/75 were positive). The bursting out of the pools show that 75 snails were carriers of F. hepatica which gives an overall infection rate of about 10.74%. The results of snails infection according to their sizes showed significant differences in the studied size classes, thus snails of big sizes were the most infected. Based on these data, epidemiological implication of Multiplex PCR as a fully reliable technique to highlight high risks periods of fasciolosis will be of a great interest.

Abstract
The mechanisms leading to skeletal limb muscle dysfunction in chronic obstructive pulmonary disease (COPD) have not been fully elucidated. Exhausted muscle regenerative capacity of satellite cells has been evocated, but the capacity of satellite cells to proliferate and differentiate properly remains unknown. Our objectives were to compare the characteristics of satellite cells derived from COPD patients and healthy individuals, in terms of proliferative and differentiation capacities, morphological phenotype and atrophy/hypertrophy signalling, and oxidative stress status. Therefore, we purified and cultivated satellite cells from progressively frozen vastus lateralis biopsies of eight COPD patients and eight healthy individuals. We examined proliferation parameters, differentiation capacities, myotube diameter, expression of atrophy/hypertrophy markers, oxidative stress damages, antioxidant enzyme expression and cell susceptibility to H2O2 in cultured myoblasts and/or myotubes. Proliferation characteristics and commitment to terminal differentiation were similar in COPD patients and healthy individuals, despite impaired fusion capacities of COPD myotubes. Myotube diameter was smaller in COPD patients (P = 0.015), and was associated with a higher expression of myostatin (myoblasts: P = 0.083; myotubes: P = 0.050) and atrogin-1 (myoblasts: P = 0.050), and a decreased phospho-AKT/AKT ratio (myoblasts: P = 0.022). Protein carbonylation (myoblasts: P = 0.028; myotubes: P = 0.002) and lipid peroxidation (myotubes: P = 0.065) were higher in COPD cells, and COPD myoblasts were significantly more susceptible to oxidative stress. Thus, cultured satellite cells from COPD patients display characteristics of morphology, atrophic signalling and oxidative stress similar to those described in in vivo COPD skeletal limb muscles. We have therefore demonstrated that muscle alteration in COPD can be studied by classical in vitro cellular models.

Abstract
313 sheep were examined in 1996 to assess the importance and seasonal evolution of Oestrus ovis infection in the Algerian region of El-Tarf. Prevalence was found to be 67.4%. The larval burden was 18 larvae by infected sheep. The prevalence was higher in older sheep than in lambs; intensity was similar. The different larval stages were found all along the year in sheep with prevalence ranging from 33.1 to 80.5% for L1, 9.7 to 43.9% for L2 and 8.4 to 23.0% for L3. The sheep were the least infected in winter (prevalence from 35.7 to 44% and intensity seven to ten larvae per sheep). The highest infection was found during the warm season (spring to autumn, prevalence from 62 to 90% and intensity ranging from 15 to 25). This larval evolution profile suggested the existence of one long cycle (November-April) and possibly two shorts cycles (May-October). This epidemiological pattern is similar to that in Morocco but was slightly different from the situation in Tunisia where the winter cycle was apparently of lesser importance.
