Abstract The adult brain contains niches of neural stem cells that continuously add new neurons to selected circuits throughout life. Two have been extensively studied in various mammalian species including humans, the subventricular zone lateral ventricles and subgranular hippocampal dentate gyrus. Recently, studies conducted mainly rodents identified a third neurogenic niche hypothalamus. In order evaluate whether cell also exists hypothalamus we performed multiple immunofluorescence...
We investigated the presence and diversity of cetaceans in Mediterranean Sea, analysing data collected by 32 different research units, over a period 15 years (2004–2018), shared on common web-GIS platform named Intercet. used encounter rate, species prevalence, Shannon index as parameters for analysis. The results show that cetacean diversity, context basin, is generally quite low when compared with eastern Atlantic, few species, namely striped dolphin, bottlenose fin whale, sperm dominate...
Abstract Sources of data other than those derived from conventional research protocols may contribute valuable information to fill gaps in knowledge about cetacean occurrences and diversity a given area help address conservation issues. The performance method examine communities based on presence records systematically shared photographs videos posted by boaters maritime operators social media (e.g. YouTube Facebook) combined with patchy distributed visual/acoustic collected researchers has...
Reproduction is safeguarded by multiple, often cooperative regulatory networks. Kisspeptin signaling, via KISS1R, plays a fundamental role in reproductive control, primarily regulation of hypothalamic GnRH neurons. We disclose herein pathway for direct kisspeptin actions astrocytes that contributes to central modulation. Protein-protein-interaction and ontology analyses proteomic profiles after stimulation revealed glial/astrocyte markers are regulated mice. This glial-kisspeptin was...
The common bottlenose dolphin is a cosmopolitan species that can be found worldwide in all oceans except polar and sub-polar waters. This wide distribution associated with certain level of morphological variation, which seems consistent the presence globally distributed pelagic/offshore ecotype several coastal/inshore ecotypes along continental shelf. In Mediterranean Sea, regularly occurring second most sighted cetacean after striped dolphin. According to some studies, more closely related...

Background The Mediterranean subpopulation of fin whale Balaenoptera physalus (Linnaeus, 1758) has recently been listed as Vulnerable by the IUCN Red List threatened species. species is also in need strict protection under Habitat Directive and one indicators for assessment Good Environmental Status MSFD. Reference values on population abundance trends are needed order to set threshold assess conservation status population. Methods Yearly summer monitoring using ferries platform opportunity...
In summer 2010 and 2011, weekly cetacean surveys were undertaken in “passing mode”, using ferries as platform of opportunity, along the “fixed line transect” between Catania Civitavecchia (Southern Italy). Of 20 species cetaceans confirmed for Mediterranean sea, 8 sighted within survey period: 7 represented by subpopulations (Balaenoptera physalus, Physeter macrocephalus, Stenella coeruleoalba, Delphinus delphis, Grampus griseus, Tursiops truncatus Ziphius cavirostris) one considered visitor...
Abstract In the adult mammalian brain, astrocytes are proposed to be major Sonic Hedgehog (Shh)-responsive cells. However, sources of Shh molecule mediating activation pathway still poorly characterized. The present work investigates distribution and phenotype cells expressing mRNA in mouse brain. Using single-molecule fluorescent situ hybridization (smfISH), we report much broader expression transcripts almost all brain regions than originally reported. We identify HuC/D + neuronal...
Astrocytes are glial cells proposed as the main Sonic hedgehog (Shh)-responsive in adult brain. Their roles mediating Shh functions still poorly understood. In hypothalamus, astrocytes support neuronal circuits implicated regulation of energy metabolism. this study, we investigated impact genetic activation signaling on hypothalamic and characterized its effects We analyzed distribution gene transcripts pathway (Ptc, Gli1, Gli2, Gli3) using single molecule fluorescence situ hybridization...
In the mature rodent brain, Sonic Hedgehog (Shh) signaling regulates stem and progenitor cell maintenance, neuronal glial circuitry brain repair. However, sources distribution of Shh mediating these effects are still poorly characterized. Here, we report in adult mouse a broad expression pattern recognized by specific monoclonal C9C5 antibody subset (11–12%) CC1+ oligodendrocytes that do not express carbonic anhydrase II. These cells also Olig2 Sox10, two oligodendrocyte lineage-specific...
Adult neurogenesis, a striking form of neural plasticity, is involved in the modulation social stimuli driving reproduction. Previous studies on adult neurogenesis have shown that this process significantly modulated around puberty female mice. Puberty critical developmental period triggered by increased secretion gonadotropin releasing hormone (GnRH), which controls activity hypothalamic-pituitary-gonadal axis (HPG). Secretion HPG-axis factors at participates to refinement circuits govern...
The loggerhead turtle is the most common sea species in Mediterranean Sea. Despite relevant research efforts, information of its distribution still scarce, particularly open where they may be exposed to different threats among which marine litter great concern. Here we investigated turtles and floating macro (FMML) Sardinia Channel Strait Sicily, a key area central Sea, by using 7 years data collected experienced observers aboard passenger ferries along commercial routes. high-risk exposure...
