In-water lidar simulations: the ALADIN ADM-Aeolus backscattered signal at 355 nm.

The Lidar Ocean Color (LiOC) Monte Carlo code has been developed to simulate the in-water propagation of the lidar beam emitted by the ALADIN ADM-Aeolus instrument in the ultraviolet (UV) spectral region (∼ 355 nm). To this end, LiOC accounts for reflection/transmission processes at the sea surface, absorption and multiple scattering in the water volume, and reflection from the sea bottom. The water volume components included in the model are pure seawater, Chlorophyll-a concentration (Chl-a), Colored Dissolved Organic Matter (CDOM), and/or a generic absorbing species.

Morphological phenotyping of the aging cochlea in inbred C57BL/6N and outbred CD1 mouse strains.

Morphological mouse phenotyping plays a pivotal role in the translational setting and even more in the area of auditory research, where mouse is a central model organism due to the evolutionary genetic relationship and morpho-functional analogies with the human auditory system. However, some results obtained in murine models cannot be translated to humans due to the inadequate description of experimental conditions underlying poor reproducibility. We approach the characterization of the aging process of the mouse cochlea in animals up to 18 months of age belonging to two of the most used outbred (CD1) and inbred (C57BL/6N) strains.

Olfactory and gustatory chemical sensor systems in the African turquoise killifish: Insights from morphology.

Smell and taste are extensively studied in fish species as essential for finding food and selecting mates while avoiding toxic substances and predators. Depending on the evolutionary position and adaptation, a discrete variation in the morphology of these sense organs has been reported in numerous teleost species. Here, for the first time, we approach the phenotypic characterization of the olfactory epithelium and taste buds in the African turquoise killifish (Nothobranchius furzeri), a model organism known for its short lifespan and use in ageing research.

Immunolocalization of Two Neurotrophins, NGF and BDNF, in the Pancreas of the South American Sea Lion and Bottlenose Dolphin .

In this study, we have investigated the immunolocalization of NGF (Nerve Growth Factor) and BDNF (Brain-Derived Neurotrophic Factor) in the pancreas of two species of marine mammals: (common bottlenose dolphin), belonging to the order of the Artiodactyla, and (South American sea lion), belonging to the order of the Carnivora. Our results demonstrated a significant presence of NGF and BDNF in the pancreas of both species with a wide distribution pattern observed in the exocrine and endocrine components. We identified some differences that can be attributed to the different feeding habits of the two species, which possess a different morphological organization of the digestive system.
