The clinical diagnosis of cutaneous melanoma always calls for histological confirmation. In addition to the recognition of the classic aspects of the neoplasm, immunohistochemistry is determinant, in particular in the assessment of the size of the replicative compartment. Generally, the proliferation rate is indicative of the neoplastic progression and is related to the clinical growth rate of the neoplasm. It allows to distinguish high risk melanomas showing a high growth rate from those of lower malignancy associated with a restricted growth rate. In melanoma, the recruitment and progression of neoplastic cells in the cell cycle of proliferation have lost some of their controls that are normally processed by a series of key regulatory molecules. In addition, the apoptotic pathway counteracting any hyperproliferative activity is released of the dependency of specific regulated molecular mechanisms. This review summarizes the current knowledge on key molecular components involved in the deregulation of the growth fraction, cell proliferation and apoptosis in melanocytic neoplasms. The implication of cyclins and of the mitogen-activated protein kinase pathways are scrutinized. The involvement of neoplastic stem cells in the metastatic process is also discussed. [less ▲]

Bluetongue is a non-contagious disease that affects domestic and wild ruminants. Since its spreading to Northern Europe in 2006, this viral epizooty caused considerable economical losses on the ovine and bovine livestock. The biological vectors of the bluetongue virus (BTV) are biting midges belonging to the genus Culicoides. Many elements still remain unknown about their biology, physiology, ecology and distribution. This study shows that these biting midges are much more abundant on farm level than in the nearby meadows; these last ones nevertheless present a much more specifi c diversity. So possibility of migration between the meadow and the farm is voiced for the C. chiopterus and C. dewulfi species. Females are much more represented than males for the farm and the meadow alike. The physiology observation of these ones is realized throughout the study. [less ▲]

Reproductive experience has significant effects on the brain, behavior and hormone profiles of the mother. Recent work has demonstrated that primiparous rats exhibit decreased dendritic arborizations in the hippocampus, and enhanced hippocampus-dependent spatial memory performance at the time of weaning compared to nulliparous and, to a lesser degree, multiparous rats. Interestingly, enhanced spatial learning and reduced dendritic arbors are seen in nulliparous female rats exposed to chronic stress or repeated corticosterone administration. Based on these observations, we hypothesized that corticosterone may be altered in primiparous rats compared to multiparous and nulliparous rats. The present study investigated whether the levels of circulating corticosterone and its binding protein, corticosteroid binding globulin (CBG), are altered with reproductive experience and pup-exposure during late pregnancy and the postpartum. Total serum corticosterone and CBG were assayed from five groups; multiparous, primiparous, nulliparous, primip-no-pups, and sensitized rats during gestation (days 14 and 19) and the postpartum period (days 1, 5, 14, 21, and 35). Results show that primiparous rats had significantly elevated total corticosterone on postpartum day 1. In addition, primiparous and multiparous rats had significantly lower CBG throughout the postpartum period than all other groups, with primiparous rats exhibiting lower levels than multiparous rats during mid-lactation. These data suggest that free corticosterone is elevated in both primiparous and multiparous dams and is elevated to a greater degree in primiparous compared to multiparous dams during lactation. Corticosterone and CBG levels were positively correlated with specific maternal behaviors during the first week postpartum in parturient rats, but not in sensitized rats, suggesting a role for corticosterone in the modulation of maternal behavior in parturient rats alone.

Nanometer-sized titanium dioxide (TiO2) particles were prepared on carbon substrates by reactive direct-current magnetron sputtering. By performing measurements with high resolution electron microscopes, the mean nanoparticle diameter and the coverage fraction of the substrate by the nanoparticles (NPs) were measured at 19 nm and 30%, respectively. Moreover, electron diffraction analysis showed that the TiO2 NPs' crystalline structure on the carbon substrate was a mixture of anatase and rutile. Finally,we provided information on the TiO2 initial growth stage: crystalline NPs were formed after deposition of amorphous nanoparticles on the substrate and heating. [less ▲]

Optimizing decisions on an ensemble of incomplete disturbance trees and aggregating their first stage decisions has been shown as a promising approach to (model-based) planning under uncertainty in large continuous action spaces and in small discrete ones. The present paper extends this approach and deals with large but highly structured action spaces, through a kernel-based aggregation scheme. The technique is applied to a test problem with a discrete action space of 6561 elements adapted from the NIPS 2005 SensorNetwork benchmark. [less ▲]

Studies leading to a better understanding of the mechanisms involved in the communication between soil microorganisms and root system can potentially lead to improved fertility management strategies. Up to now, the characterization of such interactions has been mainly focused on root exsudates but volatile organic compounds (VOC) also play a role as chemical messengers in positive interactions occurring in the rhizosphere. We aim to better understand the VOC-mediated chemical ecophysiology of soil. Wheat (Triticum aestivum L.) was chosen in this project based on its importance for food production and industrial applications. [less ▲]
