Proteome of larval metamorphosis induced by epinephrine in the Fujian oyster Crassostrea angulata

open access: yesBMC Genomics, 2020
Background The Fujian oyster Crassostrea angulata is an economically important species that has typical settlement and metamorphosis stages. The development of the oyster involves complex morphological and physiological changes, the molecular mechanisms ...

Links between metamorphosis and symbiosis in holometabolous insects

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2019
Many animals depend on microbial symbionts to provide nutrition, defence or other services. Holometabolous insects, as well as other animals that undergo metamorphosis, face unique constraints on symbiont maintenance. Microbes present in larvae encounter

The Various Shapes of Innovation

open access: yesForum of Clinical Oncology, 2015
Background: Innovation is one of the most difficult words to define, especially when it comes to health technology. The aim of this article is to get a better understanding of the multi-dimensional facet of innovation, how this is valued by different ...

Vitro culture of axe-head glochidia in pink heelsplitter Potamilus alatus and mechanism of its high host specialists. [PDF]

open access: yesPLoS ONE, 2018
The basal media M199 or MEM was utilized in the classical method of vitro culture of glochidia where 1-5% CO2 was required to maintain stable physiological pH for completion of non-parasitic metamorphosis.

Geometric Metamorphosis [PDF]

open access: yes, 2011
Standard image registration methods do not account for changes in image appearance. Hence, metamorphosis approaches have been developed which jointly estimate a space deformation and a change in image appearance to construct a spatio-temporal trajectory smoothly transforming a source to a target image.

The Characteristic of Critical Genes in Neuroendocrine System and Their Regulation on Food Habit Transition and Metamorphosis of Veined Rapa Whelk Rapana venosa (Valenciennes, 1846)

open access: yesFrontiers in Marine Science, 2021
Metamorphosis is a critical developmental event in mollusks, and neuroendocrine system plays an essential role in this process. Rapana venosa is an economically important shellfish in China, but the artificial technology of R.

Do immune system changes at metamorphosis predict vulnerability to chytridiomycosis? An update

open access: yes, 2022
Amphibians are among the vertebrate groups suffering great losses of biodiversity due to a variety of causes including diseases, such as chytridiomycosis (caused by the fungal pathogens Batrachochytrium dendrobatidis and B. salamandrivorans).

Bivalves are NO different: nitric oxide as negative regulator of metamorphosis in the Pacific oyster, Crassostrea gigas [PDF]

open access: yes, 2020
Nitric oxide (NO) is presumed to be a regulator of metamorphosis in many invertebrate species, and although NO pathways have been comparatively well-investigated in gastropods, annelids and crustaceans, there has been very limited research on the effects

Increased insulin/insulin growth factor signaling advances the onset of metamorphosis in Drosophila. [PDF]

open access: yesPLoS ONE, 2009
Mechanisms by which attainment of specific body sizes trigger developmental transitions to adulthood (e.g. puberty or metamorphosis) are incompletely understood.

Teleost Metamorphosis: The Role of Thyroid Hormone

open access: yesFrontiers in Endocrinology, 2019
In most teleosts, metamorphosis encompasses a dramatic post-natal developmental process where the free-swimming larvae undergo a series of morphological, cellular and physiological changes that enable the larvae to become a fully formed, albeit sexually ...
