The effects of assisted hatching on the hatching process and implantation [PDF]

Human Reproduction, 1996
The rationale for assisted hatching Among the numerous reasons that could explain the low implantation rate of embryos used for in-vitro fertilization (IVF), an impairment of in-vivo hatching has been proposed as a possible cause of implantation failure by Cohen et aI. (1990a).

Extended hatching periods in the subantarctic lithodid crabs Lithodes santolla and Paralomis granulosa (Crustacea: Decapoda: Lithodidae) [PDF]

, 2003
Temporal pattern of hatching was studied in the subantarctic lithodid crabs Lithodes santolla (Molina) and Paralomis granulosa (Jaquinot) from the Argentine Beagle Channel.

Hatching mechanisms of nematodes

, 1981
Investigations of nematode hatching have concentrated on the parasitic forms, especially on synchronization between host and parasite life-cycles which, in some species, is so close that the parasite is dependent on the host for the hatching stimulus ...

Results of experimental studies on suppressing the growth of micromycetes (fam. Saprolegniaceae) on egg membranes of embryos of russian sturgeon and beluga in the incubation period

Известия ТИНРО, 2022
For successful development of aquaculture, fish farms have to be provided by effective means and methods to prevent and treat diseases of fish. Many drugs are limited for using in aquaculture, so the influence of each particular drug or chemical ...

The contribution of differential hatching success to the fitness of species and interspecific hybrids

, 2007
Resting egg banks of microcrustaceans have been used to reconstruct the evolutionary and ecological history of species. However, recent studies provided evidence for a discrepancy between dormant propagules in the sediment and the planktonic population ...

The potato-eelworm hatching factor

, 1958
The hatching factor from potato root diffusate has many of the properties of eclepic acid from tomato root and Solanum nigrum (Russell, Todd & Waring, 1949), as well as the same biological activity.

Ontogenesis from Embryo to Juvenile in Threadsail Filefish, Stephanolepis cirrhifer

Animals
The threadsail filefish, Stephanolepis cirrhifer, is an economically important marine species. However, wild catches have sharply decreased over the past 20 years, causing S. cirrhifer to be added to the IUCN Red List of Threatened Species.

The Effects of Salinity and pH on Fertilization, Early Development, and Hatching in the Crown-of-Thorns Seastar

Diversity, 2017
Understanding the influence of environmental factors on the development and dispersal of crown-of-thorns seastars is critical to predicting when and where outbreaks of these coral-eating seastars will occur.

Light-dependent transcriptional events during resting egg hatching of the rotifer Brachionus manjavacas

, 2015
Rotifer resting eggs often have to endure harsh environmental conditions during the diapause phase. They are stimulated by light to hatch. In order to study the hatching mechanism, we observed resting eggs and measured their transcriptional expression ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
