Trial fermentations were performed using three experimental starter cultures with a view to selecting the most appropriate starter for use in the manufacture of Almagro eggplants. The lactic acid bacterial strains used in the starters had previously been isolated from spontaneous fermentations. The combined action of the obligate heterofermentative species Lactobacillus brevis and the facultative heterofermentative species L. plantarum yielded Almagro eggplants with sensory properties preferred ...

P system simulators are critical tools to enable them as formal modeling framework for real-life applications. Such simulators abstract the concept of P systems in various ways, depending on the needs of the users and the requirements of the specific application. We identify three main levels of abstraction: graphical user interfaces, simulation engines and parallel implementations. In this paper, we survey the state of the art at these levels and discuss the main challenges under consideration ...

In recent years, incremental sampling-based motion planning algorithms have been widely used to solve robot motion planning problems in high-dimensional configuration spaces. In particular, the Rapidly-exploring Random Tree (RRT) algorithm and its asymptotically-optimal counterpart called RRT* are popular algorithms used in real-life applications due to its desirable properties. Such algorithms are inherently iterative, but certain modules such as the collision-checking procedure can be parallelized ...

Arachidonic acid (ARA, 20:4n− 6) is essential for oysters and has been implicated in reproduction and immune response of different mollusk species, probably by modulating the levels of prostaglandins. We tested the effect of dietary ARA on reproduction, PGE2 levels, and some immune variables in Crassostrea corteziensis. Oysters were fed Isochrysis affinis galbana, clone Tahiti (T-iso) for three weeks, which has low ARA and high DHA (22:6n− 3) levels and that was supplemented with 0, 1 and 9% ARA-rich ...

We describe the quantitative and qualitative histology and histochemistry for a tropical oyster, C. corteziensis sampled in a coastal lagoon in Northwest, Mexico. Males were larger than immature oysters, with females presenting intermediate values. In this species, mature organisms were found most of the year, and there were at least two strong spawning periods, one in summer and the second in autumn. The presence of mature oocytes most of the year did not allow for differentiation of an annual ...

Fatty acid composition of cellular membranes can modify permeability and can modulate the activity of Na+/K+-ATPase. Although highly unsaturated fatty acids (HUFA) improve survival and osmoregulatory capacity to low salinities in penaeid shrimp, the possible mechanisms have not been established. For this purpose the influence of HUFA supplementation in diet (2.9 vs. 34% HUFA proportion to total fatty acids) on osmoregulatory responses of juvenile Litopenaeus vannamei submitted to an acute (15 h) or ...

Litopenaeus vannamei (Boone) grown in ponds are exposed to salinities of less than 5 g L−1 during inland shrimp culture or to more than 40 g L−1 from evaporation and reduced water exchange in dry, hot climates. However, dietary requirements for shrimp grown in low or high salinities are not well defined, particularly for fatty acids. Feeding shrimp postlarvae with highly unsaturated fatty acids (HUFA) enhances tolerance to acute exposure to low salinity, as a result of better nutritional status, or/ ...

Wild female Crassostrea corteziensis oyster (n = 245) were analyzed over one year to understand the main ecophysiological events associated to gonad development. Different indicators (mainly biochemical) were analyzed to infer: i) utilization and accumulation of energy reserves (e.g. neutral lipids, carbohydrates, proteins; vitellogenin), ii) membrane components provided by the diet as essential nutrients and indicative of cell proliferation (e.g. highly unsaturated fatty acids linked to phospholipids, ...

The aim of this study was to determine the optimal time in which the higher contents of PUFAs in juveniles of Artemia franciscana were obtained by the effect of enrichment with the tuna orbital oil emulsion. Six enrichment periods were evaluated: 3, 6, 9, 12, 15 and 18 h, in addition to a control treatment (0 h). The most abundant ...

Salinity in the oceans is changing due to climate change and global warming. Intense rainfalls and freshwater runoff decrease salinity along the coastal areas. In contrast, intense drought seasons and river damming have certainly increased salinity in lagoons and estuaries. Few studies have focused on aspects of the biology and culture of oyster Crassostrea corteziensis, but until now, physiological and immunological responses in this species have not been assessed under acute hypo- and hypersaline ...

Abstract This study examines the alignment of managers’ mental models with the strategy map provided by the balanced scorecard (BSC). By applying the cognitive maps technique to the managers of a printing firm, this work uses the distance ratio method to analyse managers’ different perceptions of the firm's resources and capabilities, as defined in the BSC. The results show a high degree of alignment between the individual manager’s mental models and of these mental models with the strategy map. ...

The lysophosphatidic acid LPA1 receptor has recently been involved in the adaptation of the hippocampus to chronic stress. The absence of LPA1 receptor aggravates the chronic stress-induced impairment of both hippocampal neurogenesis and apoptosis that were accompanied with hippocampus-dependent memory deficits. Apoptotic death and neurogenesis in the hippocampus are regulated by oxidative stress. In the present work, we studied the involvement of LPA1 receptor signaling pathway in the regulation ...

Most experimental procedures on molluscs are done after acclimatization of wild animals to lab conditions. Similarly, short-term acclimation is often unavoidable in a field survey when biological analysis cannot be done within the day of sample collection. However, acclimatization can affect the general physiological condition and particularly the immune cell responses of molluscs. Our aim was to study the changes in the hemocyte characteristics of the Pacific oyster Crassostrea gigas and the carpet ...
