Indirect genetic effects and sexual conflicts: partner genotype influences multiple morphological and behavioural reproductive traits in a flatworm [PDF]

open access: yes, 2017
The expression of an individual's phenotypic traits can be influenced by genes expressed in its social partners. Theoretical models predict that such indirect genetic effects (IGEs) on reproductive traits should play an important role in determining the ...

Substrate for Thyroid Hormone Synthesis: Biochemistry, Evolution, and Physiology

open access: yesThe FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Two proposed sequence of events for thyroxine formation in patients expressing mutant thyroglobulin. (A) (1) TSH stimulation drives expression of misfolded TG. (2) Unremitting ER stress. (3) Stress‐induced cell death. (4) Dead thyrocytes release their contents. (5) The contents become iodinated. (6) Forming thyroxine.

A novel biological activity of praziquantel requiring voltage-operated Ca2+ channel beta subunits: subversion of flatworm regenerative polarity.

open access: yesPLoS Neglected Tropical Diseases, 2009
BackgroundApproximately 200 million people worldwide harbour parasitic flatworm infections that cause schistosomiasis. A single drug-praziquantel (PZQ)-has served as the mainstay pharmacotherapy for schistosome infections since the 1980s.

Classical transmitters and their receptors in flatworms

open access: yesParasitology, 2005
The flatworm nervous system employs a wide repertoire of neuroactive substances, including small chemical messengers, the so called classical transmitters, and several types of neuropeptides. A large body of research accumulated over four decades has provided a wealth of information on the tissue localization and effects of these substances, their ...

The Oyster Industry of Eastern Mexico [PDF]

open access: yes, 1997
Mexico has an oyster industry of substantial size, ranking about sixth in the world. In 1993, among the top ten oyster producers, Korea, Japan, the United States, China, and France ranked ahead of Mexico, while the Philippines, Australia, Canada, and New

Light-sheet microscopy for everyone? Experience of building an OpenSPIM to study flatworm development. [PDF]

open access: yes, 2016
Background: Selective plane illumination microscopy (SPIM a type of light-sheet microscopy) involves focusing a thin sheet of laser light through a specimen at right angles to the objective lens.

Conservation and diversification of small RNA pathways within flatworms

open access: yesBMC Evolutionary Biology, 2017
Background Small non-coding RNAs, including miRNAs, and gene silencing mediated by RNA interference have been described in free-living and parasitic lineages of flatworms, but only few key factors of the small RNA pathways have been exhaustively ...

Neuropeptide signalling systems in flatworms

open access: yesParasitology, 2005
Two distinct families of neuropeptides are known to endow platyhelminth nervous systems – the FMRFamide-like peptides (FLPs) and the neuropeptide Fs (NPFs). Flatworm FLPs are structurally simple, each 4–6 amino acids in length with a carboxy terminal aromatic-hydrophobic-Arg-Phe-amide motif. Thus far, four distinct flatworm FLPs have been characterized,
