Serotonin stimulates Echinococcus multilocularis larval development [PDF]

open access: yesParasites & Vectors, 2021
AbstractBackgroundSerotonin is a phylogenetically ancient molecule that is widely distributed in most metazoans, including flatworms. In addition to its role as a neurotransmitter, serotonin acts as a morphogen and regulates developmental processes. Although several studies have focused on the serotonergic nervous system in parasitic flatworms, little ...

Developing retinotectal projection in larval goldfish [PDF]

open access: yesJournal of Comparative Neurology, 1989
AbstractThe retinotectal projection in larval goldfish was studied with the aid of anterograde filling of optic fibers with HRP applied to the retina. The results show that optic fibers have already reached the tectum and begun to form terminal arbors in newly hatched fish.

Head Capsule Widths as an Indicator of the Larval Instar of Codling Moth (Lepidoptera: Olethreutidae) [PDF]

open access: yes, 2017
Head capsule width was a reliable indicator of larval instar in a strain of Michigan codling moths, Cydia pomonella. Head capsules were 0.33, 0.50, 0.82, 1.18 and 1.55 mm in width from first to fifth instar respectively.

The Enigmatic Canal-Associated Neurons Regulate Caenorhabditis elegans Larval Development Through a cAMP Signaling Pathway. [PDF]

open access: yes, 2019
Caenorhabditis elegans larval development requires the function of the two Canal-Associated Neurons (CANs): killing the CANs by laser microsurgery or disrupting their development by mutating the gene ceh-10 results in early larval arrest. How these cells

Experimental Control and Characterization of Autophagy in Drosophila [PDF]

open access: yes, 2008
Insects such as the fruit fly Drosophila melanogaster, which fundamentally reorganize their body plan during metamorphosis, make extensive use of autophagy for their normal development and physiology.

Temporal scaling in C. elegans larval development. [PDF]

open access: yesProc Natl Acad Sci U S A, 2022
Significance An enduring mystery of development is how its timing is controlled, particularly for development after birth, where timing is highly flexible and depends on environmental conditions, such as food availability and diet.

Gonad index and larval development of the sand dollar Dendraster excentricus (Echinodermata; Echinoidea) in Baja California, Mexico

open access: yesCiencias Marinas, 2012
The sand dollar Dendraster excentricus has been extensively used in diverse studies in Baja California (Mexico). This study shows annual variations in the gonad index and describes larval development under laboratory conditions of D. excentricus. Over a

Assessment of Embryonic and Larval Development of Nile Tilapia under the Traditional and Re-Circulatory Thermostatic System in Relation to Climatic and Water Quality Variations

open access: yesAquaculture Journal, 2023
Embryonic and larval development of tilapia (Oreochromis niloticus) is very vulnerable to climate change. This study was conducted for an assessment of the embryonic and larval development of Nile tilapia in traditional hatchery and re-circulatory ...
