Kinetic profiling an abundantly expressed planarian serotonergic GPCR identifies bromocriptine as a perdurant antagonist

International Journal for Parasitology: Drugs and Drug Resistance, 2016
The diversity and uniqueness of flatworm G protein coupled receptors (GPCRs) provides impetus for identifying ligands useful as tools for studying flatworm biology, or as therapeutics for treating diseases caused by parasitic flatworm infections.

Sensitivity of Planaria to Weak, Patterned Electric Current and the Subsequent Correlative Interactions with Fluctuations in the Intensity of the Magnetic Field of Earth

J, 2020
Some species of fish show highly evolved mechanisms by which they can detect exogenous electric and magnetic fields. The detection of electromagnetic fields has been hypothesized to exist in humans, despite the lack of specialized sensors.

Observations on food preference of Neotropical land planarians (Platyhelminthes), with emphasis on Obama anthropophila , and their phylogenetic diversification

Zoologia (Curitiba), 2017
: The food preference of Obama anthropophila Amaral, Leal-Zanchet & Carbayo, 2015, a species that seems to be spreading across Brazil’s human-modified environments, was investigated.

Sexual selection in a transparent worm : insights from fluorescent sperm [PDF]

, 2015
Sexual selection is a potent source of selection underlying the evolution of sexual dimorphism, reproductive strategies and mating systems. Although sexual selection was initially thought to occur exclusively at the pre-copulatory stage (e.g., contests ...

Complete mitogenome of the giant invasive hammerhead flatworm Bipalium kewense

Mitochondrial DNA. Part B. Resources, 2019
We determined the sequence of the complete mitogenome of Bipalium kewense, an invasive land flatworm with worldwide distribution. All 37 genes encoded on this 15,666-bp genome reside on the same DNA strand. Phylogenomic analyses of mitochondrial proteins

Stem cell heterogeneity drives the parasitic life cycle of Schistosoma mansoni

eLife, 2018
Schistosomes are parasitic flatworms infecting hundreds of millions of people. These parasites alternate between asexual reproduction in molluscan hosts and sexual reproduction in mammalian hosts; short-lived, water-borne stages infect each host ...

Identification of thioredoxin glutathione reductase inhibitors that kill cestode and trematode parasites. [PDF]

PLoS ONE, 2012
Parasitic flatworms are responsible for serious infectious diseases that affect humans as well as livestock animals in vast regions of the world. Yet, the drug armamentarium available for treatment of these infections is limited: praziquantel is the ...

Praziquantel use in aquaculture – Current status and emerging issues

International Journal for Parasitology: Drugs and Drug Resistance, 2022
Parasitic diseases are major constraints in fish mariculture. The anthelmintic praziquantel (PZQ) can effectively treat a range of flatworm parasites in a variety of fish species and has potential for broader application than its current use in the ...

A novel flatworm-specific gene implicated in reproduction in Macrostomum lignano [PDF]

, 2018
Free-living flatworms, such as the planarian Schmidtea mediterranea, are extensively used as model organisms to study stem cells and regeneration. The majority of flatworm studies so far focused on broadly conserved genes.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...
