Myeloperoxidase (MPO) is a pro-oxidant enzyme associated with decreased motility in thawed equine semen. This study aimed to describe MPO concentration, activity and subunits in raw and thawed semen and to correlate these data with motilities in raw and thawed semen. Semen samples from five stallions were collected four times. Motilities were assessed in raw and thawed semen. MPO assays were performed in raw seminal plasma, raw sperm-rich pellet and thawed semen. Total and active MPO concentrations were, respectively, assayed by enzyme-linked immunosorbent assay and specific immunological extraction followed by enzymatic detection. MPO subunits present in semen were characterized by Western 3 blot. Purified active MPO was added in PBS and freezing extender to control its activity during freezing procedure. Differences between medians were determined using Kruskal– Wallis test, and correlations were determined using Spearman’s test for nonparametric data. Active MPO concentration was low in seminal plasma and thawed semen, but high in pellet (p = 0.0058), as the opposite relation was observed for total MPO concentration (p < 0.0001). In seminal plasma and post- thaw semen, inactive 86-kDa MPO precursor was mainly observed. Purified MPO activity was decreased in the extender (p = 0.0286). MPO activity in pellet was highly correlated with thawed progressive motility (r = 􏰑0.5576, p = 0.0086). Inac- tive MPO precursor and unknown low molecular weight inactive MPO precursor subunits explain low MPO activity in semen. Major MPO activity was observed in pellet, and post- thaw loss of activity is partially explained by MPO inactiva- tion in extender. Thawed semen motility was negatively correlated with MPO activity in pellet, becoming a potential freezability predictor. [less ▲]

The aim of this study is to characterize monovarietal virgin olive oils (VOOs) of new high-density plantings system of three cultivars (Arbequina, Arbosana and Koroneiki) which have been recently introduced in the eastern mediterranean region of Morocco. In this study, we have also conducted comparison between those monovarietal VOOs and olive oil of the local olive cultivar Picholine marocaine. Monovarietal VOOs characterization has been carried out by analysing several parameters, including quality index and olive oil stability to oxidation. Significant differences between the analysed olive oils were highlighted. They depend on cultivars and technological conditions of processing. We have noticed that Koroneiki olive oil have higher content of phenols (459.48 mg kg-1) and have the best value of oxidative stability (93.16 h). On the other hand Arbrosana’s VOO has low content of total phenols (260.85 mg kg-1) but it was distinguished by its higher content of alpha-tocopherol (460.07 mg kg-1). In addition, ten phenolic compounds present in virgin olive oils, were identified and quantitatively assessed by HPLC. Hydroxytyrosol, tyrosol, luteoline, pinoresinol and apigenin were the main phenolic compounds in those analyzed monovarietal VOOS. [less ▲]

In this paper we present new and review already existing landslide and earthquake data for a large part of the Tien Shan, Central Asia. For the same area, only partial databases for sub-regions have been presented previously. They were compiled and new data were added to fill the gaps between the databases. Major new inputs are products of the Central Asia Seismic Risk Initiative (CASRI): a tentative digital map of active faults (even with indication of characteristic or possible maximum magnitude) and the earthquake catalogue of Central Asia until 2009 that was now updated with USGS data (to May 2014). The new compiled landslide inventory contains existing records of 1600 previously mapped mass movements and more than 1800 new landslide data. Considering presently available seismo-tectonic and landslide data, a target region of 1200 km (E–W) by 600 km (N–S) was defined for the production of more or less continuous geohazards information. This target region includes the entire Kyrgyz Tien Shan, the South-Western Tien Shan in Tajikistan, the Fergana Basin (Kyrgyzstan, Tajikistan and Uzbekistan) as well as the Western part in Uzbekistan, the North-Easternmost part in Kazakhstan and a small part of the Eastern Chinese Tien Shan (for the zones outside Kyrgyzstan and Tajikistan, only limited information was available and compiled)...

Lignocellulosic biomass residues have attracted attention for the sustainable production of molecules for material and energetic use through biochemical conversion. Their recalcitrant structure prevents a broader use and asks for the development of sustainable techniques that can efficiently separate, recover and valorize the constituting components. In a cascading concept, residual streams of such processes can be further exploited in an attempt to valorize the largest possible fraction of the initial material. Three lignocellulosic substrates, namely dried sugar beet pulp, wheat bran and miscanthus straw, were upstream fractionated by steam explosion to extract the hemicellulose fraction. This study evaluated the valorization of the residual solid fraction through mixed acidogenic fermentation for the production of volatile fatty acids (VFA) as platform chemicals. Batch experiments have been conducted for the reference material (non-treated) and the solid fraction remaining after steam explosion, with and without the addition of an external mixed inoculum. Steam explosion residues contained less hemicellulose than the initial materials. The difference in the fermentation profile between steam explosion residues and non-treated substrates is dependent on the substrate. Maximum total VFA (tVFA) concentration was 18.8 gCOD/kgmixed_liquor, and maximum yield of chemical oxygen demand (COD) conversion into tVFAwas 33 % for the case of non-treated inoculated beet pulp.
