Spatial Metabolomics Reveals the Multifaceted Nature of Lamprey Buccal Gland and Its Diverse Mechanisms for Blood-Feeding

open access: yesCommunications Biology, 2023
Lampreys are blood-sucking vampires in marine environments. From a survival perspective, it is expected that the lamprey buccal gland exhibits a repository of pharmacologically active components to modulate the host’s homeostasis, inflammatory and immune

Characteristics of the population of Lampetra fluviatilis (L.) entering the Drwęca and Grabowa rivers (North Poland) [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1995
The size, length/weight relationship, sex ration and gonadosomatic index of the autumn and spring upstream run populations of the river lamprey have been studied.

Persistence of skin marks on killer whales (Orcinus orca) caused by the parasitic sea lamprey (Petromyzon marinus) in Iceland [PDF]

open access: yes, 2011
Lampreys have long been thought to be a cetacean ectoparasite, due to the observation of round marks on the skin of whales caught during whaling operations.

Origin of serpin-mediated regulation of coagulation and blood pressure. [PDF]

open access: yesPLoS ONE, 2014
Vertebrates evolved an endothelium-lined hemostatic system and a pump-driven pressurized circulation with a finely-balanced coagulation cascade and elaborate blood pressure control over the past 500 million years.

Expression of Urocortin 3 mRNA in the Central Nervous System of the Sea Lamprey Petromyzon marinus

open access: yesBiology, 2021
In this study, we analyzed the organization of urocortin 3 (Ucn3)-expressing neuronal populations in the brain of the adult sea lamprey by means of in situ hybridization.

Bifurcations in valveless pumping techniques from a coupled fluid-structure-electrophysiology model in heart development [PDF]

open access: yes, 2017
We explore an embryonic heart model that couples electrophysiology and muscle-force generation to flow induced using a $2D$ fluid-structure interaction framework based on the immersed boundary method.

Monitoring anadromous fish populations in a context of habitat fragmentation and commercial exploitation

open access: yesFrontiers in Marine Science, 2015
River Mondego represents a stronghold for anadromous fish species highly interesting from conservation and socioeconomic views, like sea lamprey (Petromyzon marinus L.), allis shad (Alosa alosa L.) and twaite shad (Alosa fallax Lacépède, 1800).

Unravelling the functional development of vertebrate pathways controlling gaze

open access: yesFrontiers in Cell and Developmental Biology, 2023
Animals constantly redirect their gaze away or towards relevant targets and, besides these goal-oriented responses, stabilizing movements clamp the visual scene avoiding image blurring. The vestibulo-ocular (VOR) and the optokinetic reflexes are the main

Thyroid and endostyle development in cyclostomes provides new insights into the evolutionary history of vertebrates

open access: yesBMC Biology, 2022
Background The endostyle is an epithelial exocrine gland found in non-vertebrate chordates (amphioxi and tunicates) and the larvae of modern lampreys.

Circuits regulating pleasure and happiness:the evolution of reward-seeking and misery-fleeing behavioral mechanisms in vertebrates

open access: yesFrontiers in Neuroscience, 2015
The very first free-moving animals in the oceans over 540 million years ago must have been able to obtain food, territory and shelter, as well as reproduce.
