Developmental Biology, 2000 A lesson learned from modern developmental biology is the striking degree of conservation of strategies and molecules used to program developmental events in species as diverse as insects, birds, amphibians, and mammals. Nonetheless, mammals retain distinctions with regard to the strategies used to protect and nourish their offspring during development,

On the multiple generations of planetary embryos [PDF]
, 2022 Global models of planet formation tend to begin with an initial set of planetary embryos for the sake simplicity. While this approach gives valuable insights on the evolution of the initial embryos, the initial distribution itself is a bold assumption.

In vitro production of bovine embryos derived from individual donors in the Corral® dish [PDF]
, 2017 Background: Since the identity of the embryo is of outmost importance during commercial in vitro embryo production, bovine oocytes and embryos have to be cultured strictly per donor.

Effects of pregnancy on neuromyelitis optica spectrum disorder and predictors of related attacks
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1918-1925, December 2022., 2022 Abstract Objective Our study aimed to investigate the influence of pregnancy on the course of neuromyelitis optica spectrum disorders (NMOSD) and to explore the independent predictors of pregnancy‐related attacks. Methods We performed a retrospective study of patients with NMOSD based on the Wingerchuk 2006 or the revised Wingerchuk 2015 criteria ...

On the interaction of pebble accreting embryos with the gaseous disc: importance of thermal forces [PDF]
, 2023 A planetary embryo embedded in a gaseous disc can grow by pebble accretion while subjected to a gravitational force from the disc that changes its orbital elements. Usually, that force is considered to arise from the Lindblad and corotation resonances with the embryo. However, more important contributions exist for low-mass planets.

Proceedings of the National Academy of Sciences, 2011 Generation of transgenic mice by pronuclear DNA injection into fertilized eggs has been well-established for over 30 y (1). However, it remains a rather crude approach: injected sequences randomly insert as concatamers, they can be mutagenic, and they have variable expression depending on the site of integration, a phenomenon called position effects ...

Brain magnetic resonance imaging predictors in anti‐N‐methyl‐D‐aspartate receptor encephalitis
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1974-1984, December 2022., 2022 Abstract Objective Brain magnetic resonance imaging (MRI) findings in anti‐N‐methyl‐D‐aspartate receptor (NMDAR) encephalitis are nonspecific and rarely have obvious associations with clinical characteristics and outcomes. This study aimed to comprehensively describe the MRI features of patients with NMDAR encephalitis, examine their associations with ...
