EGGSHELL AND EGG CONTENT TRAITS IN PEKING DUCK EGGS FROM THE P44 RESERVE FLOCK RAISED IN POLAND [PDF]

open access: yes, 2007
The egg quality of Peking ducks was evaluated on three different dates (the beginning, peak, end) of the first egg laying period. During the laying period the following increases were noted: in egg weight (from 71.7 to 86.7 g), in length (from 61.9 to 65.

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.

Application of Conductivity Combined with Various Other Instrumental Analyses in the Detection of the Freshness and Yolk-to-White Ratio of Liquid Egg [PDF]

open access: yesShipin Kexue
This study established a rapid and efficient technique to detect the freshness and yolk-to-white ratio of liquid egg based on conductivity combined with salinity, total dissolved solids (TDS), pH, and color parameters. The results showed that during the

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 ...

Comparative Study of Microwave and Ultrasound-Assisted Extraction of Phosvitin From Egg Yolk. [PDF]

open access: yesFood Sci Nutr
Microwave‐assisted extraction produced phosvitin with greater purity and recovery compared to ultrasound‐based methods. An increase in microwave power and processing time was positively correlated with both phosvitin purity and HDL removal efficiency, as confirmed by FT‐IR analysis and SDS‐PAGE electrophoresis profiles.

Observations on the physiological development of trout eggs [Translation from: Roux. Arch. f. Entwicklungsmechanik der Organismen, 114. 771, 1929] [PDF]

open access: yes, 1929
The osmotic pressure of the perivitelline fluid and the yolk of trout (Salmo trutta) eggs were measured separately by the Drucker-Schrein method. The permeability of the egg membrane and the variations in the osmotic pressure of the eggs when placed in ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Incubation of penguin eggs [PDF]

open access: yes, 2003
The preservation of rare and endangered species of birds requires finding efficient, and above all successful, methods of breeding them in captivity. One strategy adopted is to remove eggs from the mother, making her lay more eggs, and then incubating ...
