Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

open access: yesBiological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Avaliação de óleos, carvão vegetal e vitamina E no desempenho e nas concentrações lipídicas do sangue e dos ovos de poedeiras Evaluation of oil, vegetal charcoal and E vitamin on performance and on blood and egg lipid concentrations of laying hens

open access: yesRevista Brasileira de Zootecnia, 2010
Foram estudados os efeitos de duas fontes de óleo vegetal, de carvão e de vitamina E sobre o desempenho e os níveis lipídicos do sangue e dos ovos de poedeiras comerciais. Utilizaram-se poedeiras Lohmann Brown e Lohmann LSL com 58 semanas de idade.

Engineered Carbon Dots as Multifunctional Nanoplatforms for Next‐Generation High‐Performance Advanced Batteries

open access: yesCarbon Energy, EarlyView.
Herein, we mainly summarize the characteristics of the main types of carbon dots (CDs), analyze the strategies for improving advanced batteries' performance via incorporating CDs, comprehensively summarize recent applications of CDs in the main components (electrode, electrolyte, and separator) of advanced batteries, and propose the technical ...

Ultrastructural characteristics of yolk in the chicken egg. Mechanisms for yolk absorption and its digestion by the yolk sac at different stages of embryonic development.

open access: yes, 1994
An ultrastructural study using electron microscopy was undertaken of yolk and yolk sac to elucidate digestive mechanisms and to gather evidence to further substantiate the belief that intracellular digestion of yolk takes place in yolk sac epithelial ...

Engineering Mechanically Adaptive Nanonetworks for Long‐Life and High‐Capacity Silicon Anode Batteries

open access: yesCarbon Energy, EarlyView.
ABSTRACT Silicon anodes, with a theoretical capacity of ~3860 mAh g−1, offer more than ten times the lithium storage of graphite but suffer from large volume expansion during lithiation, leading to particle fracture, electrical disconnection, and unstable solid–electrolyte interphases (SEIs). In this study, we present a rheology‐guided materials design

Yolk Pigmenters

open access: yes, 1972
Commercial quantities of deeply pigmented egg yolk are used by certain food manufacturers to give desirable yellow color to some of their products. Yellow com and alfalfa meal are the major natural sources of the yellow pigments (xanthophylls) found in ...

Yolk sac histology.

open access: yes, 2014
(A) On day E8.5, Haematoxylin and Eosin (H&E) staining and α-SMA immunohistochemistry show comparable integrity, erythrocyte filling, α-SMA staining of the mesodermal layer of homozygous asTFKI and wt yolk sacs. (B) On day E9.5, erythrocyte content, wall

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

open access: yesCytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Age-related patterns of yolk androgen deposition in spotless starlings [dataset]

open access: yes, 2019
Female birds can influence offspring development by adjusting egg size or by a differential allocation of egg resources. Such maternal effects can be expected to be shaped by natural selection, given the costs connected to the allocation of maternal ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...
