Increasing global temperature and sea-level rise have led to concern about expansions in the distribution and prevalence of complex-lifecycle parasites (CLPs). Indeed, numerous environmental variables can influence the infectivity and reproductive output of many pathogens. Digenean trematodes are CLPs with intermediate invertebrate and definitive vertebrate hosts. Global warming and sea ...

Mollusks are the most morphologically disparate living animal phylum, they have diversified into all habitats, and have a deep fossil record. Monophyly and identity of their eight living classes is undisputed, but relationships between these groups and patterns of their early radiation have remained elusive. Arguments about traditional morphological phylogeny ...

Abstract Recent progress in animal welfare legislation relating to invertebrates has provoked interest in methods for the anesthesia of cephalopods, for which different approaches to anesthesia have been tried but in most cases without truly anesthetizing the animals. For example, several workers have used muscle relaxants or hypothermia as forms ...

Angiostrongylus vasorum, a parasite of the cardiorespiratory system in canids, has a heteroxenous biological cycle in which the intermediate hosts are terrestrial and aquatic mollusks. Generally, canids become infected by ingesting the intermediate host or paratenic hosts, such as amphibians, that contain infective larvae (L3). However, there are no reports ...

Bacteria play many important roles in animal digestive systems, including the provision of enzymes critical to digestion. Typically, complex communities of bacteria reside in the gut lumen in direct contact with the ingested materials they help to digest. Here, we demonstrate a previously undescribed digestive strategy in the wood-eating marine ...

Inflammation and cancer are related pathologies acting synergistically to promote tumor progression. In both, hematogenous metastasis and inflammation, P-selectin participates in interactions involving tumor cells, platelets, leukocytes, and endothelium. Heparin has been shown to inhibit P-selectin and as a consequence it blunts metastasis and inflammation. Some heparin analogues obtained from ...

The mollusk shell nacre layer integrates mineral phases with macromolecular components such as intracrystalline proteins. However, the roles performed by intracrystalline proteins in calcium carbonate nucleation and subsequent post-nucleation events (e.g., organization of mineral deposits) in the nacre layer are not known. We find that AP7, a nacre intracrystalline C-RING ...

Dehydroepiandosterone (DHEA), the most abundant steroid in humans, affects multiple cellular functions of the endocrine, immune and nervous systems. However, up to quite recently no receptor has been described specifically for it while most of its physiological actions have been attributed to its conversion to either androgens or estrogens. DHEA ...

Organotin compounds, such as tributyltin (TBT) and triphenyltin (TPT), are typical environmental contaminants and suspected endocrine-disrupting chemicals because they cause masculinization in female mollusks. In addition, previous studies have suggested that the endocrine disruption by organotin compounds leads to activation of peroxisome proliferator-activated receptor (PPAR)γ and retinoid X receptor (RXR). ...

BackgroundWith more than 100,000 living species, mollusks are the second most diverse metazoan phylum. The current taxonomic classification of mollusks recognizes eight classes (Neomeniomorpha, Chaetodermomorpha, Polyplacophora, Monoplacophora, Cephalopoda, Gastropoda, Bivalvia, and Scaphopoda) that exhibit very distinct body plans. In the past, phylogenetic relationships among mollusk classes have been contentious due ...

Cephalochordates, the sister group of tunicates plus vertebrates, have been called "living fossils" due to their resemblance to fossil chordates from the Cambrian. The genome of the cephalochordate Branchiostoma floridae shares remarkable synteny with vertebrates and is free from whole genome duplication. We performed RNA sequencing (RNA-Seq) from larvae and ...
