Impact of higher temperatures on yolk sac absorption and early development in hybrid catfish between Clarias gariepinus and C. macrocephalus

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract Climate change has driven global temperature increases, resulting in severe heat waves, altered precipitation patterns, and extreme weather events. In April 2024, a massive die‐off of hybrid catfish larvae and fry occurred in Thai aquaculture farms, coinciding with elevated temperatures of air (37–41°C) and freshwater (30–32°C).

Embryonic and intracapsular larval development of Plicopurpura pansa (Gould, 1853) (Prosobranchia, Muricidae) under laboratory conditions

open access: yesCiencias Marinas, 2004
The embryonic development of the marine muricid Plicopurpura pansa (Gould, 1853) until hatching is described. Each female spawned about 150 egg capsules in a 10-week period.

Cell lineage of the Ilyanassa embryo: evolutionary acceleration of regional differentiation during early development. [PDF]

open access: yesPLoS ONE, 2009
Cell lineage studies in mollusk embryos have documented numerous variations on the lophotrochozoan theme of spiral cleavage. In the experimentally tractable embryo of the mud snail Ilyanassa, cell lineage has previously been described only up to the 29 ...

Structural Analysis of Embryonic Development of Embryos From the Crossing of Two Species of Siluriform

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Based on the need for knowledge about the biology of hybrid fish specimens currently being produced by commercial fish farmers, this study aimed to study the initial ontogenesis up to the fifth day after larval hatching of the Hybrid LP produced by crossing Leiarius marmoratus (♀) and Pseudoplatystoma reticulatum (♂), thus producing important data for ...

The emerging roles of UFMylation in the modulation of immune responses

open access: yesClinical and Translational Medicine, Volume 14, Issue 9, September 2024.
UFMylation regulates cGAS‐STING and RIG‐I pathways to defend pathogens. UFMylation regulates the PD‐1/PD‐L1 checkpoint. UFMylation component UFBP1 regulates the function of B cells. UFMylation regulates inflammation‐related pathways (e.g., TLRs and NF‐κB).

Biochemical characterization of three BLT receptors in zebrafish.

open access: yesPLoS ONE, 2015
The leukotriene B4 (LTB4) receptor 1 (BLT1) is a high affinity receptor for LTB4, a chemotactic and inflammatory eicosanoid. The LTB4 receptor 2 (BLT2) was originally identified as a low affinity receptor for LTB4, and, more recently, as a high affinity ...

Embryonic and larval development of yellow perch (Perca flavescens) and its sensitivity to incubation temperature

open access: yesJournal of Fish Biology, Volume 105, Issue 3, Page 735-751, September 2024.
Abstract The ontogenetic development in teleost fish is sensitive to temperature, and the developmental rate has a direct relationship with the environmental temperature within a species' thermal tolerance limit. Temperature determines time to and survival at hatching.

Developmental and genomic insight into the origin of the tardigrade body plan

open access: yesEvolution &Development, Volume 26, Issue 4, July 2024.
Three hypotheses for the homology of tardigrade segments to segments of other panarthropods. H, tardigrade head; T1‐T4, tardigrade trunk segment 1–trunk segment 4. Abstract Tardigrada is an ancient lineage of miniaturized animals. As an outgroup of the well‐studied Arthropoda and Onychophora, studies of tardigrades hold the potential to reveal ...

Requirement of Npc1 and availability of cholesterol for early embryonic cell movements in zebrafish[S]

open access: yesJournal of Lipid Research, 2011
Niemann-Pick disease, type C (NP-C), often associated with Niemann-Pick disease, type C1 (NPC1) mu­tations, is a cholesterol-storage disorder characterized by cellular lipid accumulation, neurodegeneration, and reduced steroid production.

Protocol for extracting live blastoderm cells from embryos of annual killifish

open access: yesSTAR Protocols, 2023
Summary: The implementation of in vitro approaches using undifferentiated embryonic cells from annual killifish to complement existing in vivo developmental studies has been hindered by a lack of efficient isolation techniques.
