Microglial GPR35 Ameliorates Epileptogenesis and Neuroinflammation via PDGFA Domain 2 Signaling

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
Activation of microglial G protein–coupled receptor 35 (GPR35) by L‐kynurenic acid (L‐Kyna) initiates a platelet‐derived growth factor A (PDGFA)–dependent phosphoinositide 3‐kinase–protein kinase B (PI3K–AKT) signaling cascade that dampens hippocampal neuroinflammation, thereby restraining epileptogenesis, lowering seizure susceptibility, and ...

A Sketch of a Sirenia: Meros Theory [PDF]

open access: yes
This sketch of a perhaps future 'Elementary Theory of the Category of Mereological Sums (including Mereological Wholes and Parts)' relates to my previous papers "The Topos of Emergence" and "Intelligible Gunk". I assert that for successfully categorizing

Morphology, morphometry and ultrastructure of the Amazonian manatee (Sirenia: Trichechidae) spermatozoa

open access: yesZoologia (Curitiba), 2010
This study describes the morphological, morphometric and ultrastructural characteristics of the Amazonian manatee Trichechus inunguis (Natterer, 1883) spermatozoon. The spermatozoa were obtained from a urine sample of an adult T.

Fast ripple‐delta coupling as an early biomarker for post‐traumatic epileptogenesis in repetitive brain injury

open access: yesEpilepsia Open, Volume 11, Issue 2, Page 409-421, April 2026.
Abstract Objective Traumatic brain injury (TBI) can induce posttraumatic epilepsy (PTE), but early biomarkers for epileptogenesis are lacking. We aimed to investigate electrographic biomarkers before and during posttraumatic seizure development. Methods We used a repetitive diffuse TBI model in mice with continuous video‐EEG monitoring up to 4½ months ...

Calponin‐3 is associated with epilepsy through the regulation of astrocyte activity

open access: yesBrain Pathology, Volume 36, Issue 2, March 2026.
Increased calponin‐3 expression correlates with astrocyte activation in epileptic mice, modulating adenosine metabolism regulators ADK and ENT1. Calponin‐3 overexpression increased susceptibility to epileptic seizures, while its downregulation reduces spontaneous recurrent seizures, identifying it as a potential therapeutic target for epilepsy ...

Foods and feeding habits of wild and captive Sirenia

open access: yes, 1981
The Sirenia along with the elephants and hyraxes form the Super‐Order Paenungulata. They are the only fully aquatic mammalian herbivores and are represented by three species of manatees (Trichechidae), the dugong and the now extinct, Steller's sea cow ...

The epizoic diatom Campylodiscus cf. clypeus (Bacillariophyta: Surirellaceae), a new symbiont of the Caribbean manatee in Mexico

open access: yesCaldasia, 2018
Observations on the epizoic interaction between diatoms and marine mammals have been conducted mostly in cetaceans and are scarce in sirenians. By scraping the skin surface, the samples of biofilm were collected of a captive male Caribbean manatee in ...
