Maternal lipid profile during early pregnancy and birth weight: A retrospective study
IntroductionElevated maternal serum lipid concentrations have been related to an adverse intrauterine environment and lead to abnormal birth weight.ObjectiveIn this study, we aimed to explore the association between maternal lipid profiles during early ...

MicroRNA Signaling in Embryo Development [PDF]
Expression of microRNAs (miRNAs) is essential for embryonic development and serves important roles in gametogenesis. miRNAs are secreted into the extracellular environment by the embryo during the preimplantation stage of development. Several cell types secrete miRNAs into biological fluids in the extracellular environment.

The development of the cloaca in the human embryo [PDF]
Abstract Subdivision of cloaca into urogenital and anorectal passages has remained controversial because of disagreements about the identity and role of the septum developing between both passages. This study aimed to clarify the development of the cloaca using a quantitative 3D morphological approach in human embryos of 4–10 post ...

Response of the Developing Embryo to Light
Abstract INTRODUCTION Attempts by this laboratory to grow chick embryos outside the shell were met with limited success (Boone, 1963). Among the environmental factors altered by the in vitro method of growing embryos was exposure to light. Boone (1969) found that average livability was 3.7 and 2.7 days in black painted and ordinary beakers ...

An in vitro stem cell model of human epiblast and yolk sac interaction
Human embryogenesis entails complex signalling interactions between embryonic and extra-embryonic cells. However, how extra-embryonic cells direct morphogenesis within the human embryo remains largely unknown due to a lack of relevant stem cell models ...

Neuron development in human embryos [PDF]
Human Biology Mammalian fertility depends on the secretion of gonadotropin-releasing hormone (GnRH) from a population of specialized neurons residing in the hypothalamus. During embryogenesis, these neurons develop at the olfactory placodes, and they subsequently migrate to the brain.

ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated.
