Incubation of penguin eggs [PDF]

, 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 ...

The influence of different salinity conditions on egg buoyancy and development and yolk sac larval survival and morphometric traits of Baltic Sea sprat (Sprattus sprattus balticus Schneider) [PDF]

, 2009
The small pelagic sprat (Sprattus sprattus) is a key ecologic player in the Baltic Sea. However, there is long-term variability in recruitment which is thought to be influenced by fluctuations in abiotic and biotic conditions experienced during the early

Effect of the ratio of dietary n-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid on broiler breeder performance, egg quality, and yolk fatty acid composition at different breeder ages.

Poultry Science, 2014
When added to the feed of broiler breeder hens, dietary polyunsaturated fatty acids (FA) can be incorporated into the yolk and therefore become available to the progeny during their early development.

A Comparative Evaluation of Exoenzyme Production, Biofilm Development, and Cell Surface Hydrophobicity in Dominant Genotypes of Candida albicans

Journal of Clinical Laboratory Analysis, EarlyView.
Schematic overview of virulence trait assessment in Candida albicans clinical isolates. ABSTRACT Background Candida albicans exhibits significant genotypic diversity, and genotypes A and C are the most predominant clinical isolates. The aim of this study was to evaluate the virulence traits of these genotypes, focusing on exoenzyme production, biofilm ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Four-way regulation of mosquito yolk protein precursor genes by juvenile hormone-, ecdysone-, nutrient-, and insulin-like peptide signaling pathways. [PDF]

, 2014
Anautogenous mosquito females require a meal of vertebrate blood in order to initiate the production of yolk protein precursors by the fat body. Yolk protein precursor gene expression is tightly repressed in a state-of-arrest before blood meal-related ...

In vitro radionuclide labeling characteristics of blenderized tube feeds for quantitative gastric motility assessment

JPGN Reports, EarlyView.
Abstract Gastric emptying scintigraphy (GES) using technetium‐99m‐sulfur colloid (99mTc‐SC) is an important tool for evaluating feeding intolerance. Stable 99mTc‐SC binding to the solid component of the meal is imperative for accurate result interpretation.

Symptoms of egg yolk‐associated food protein‐induced enterocolitis syndrome appear following prolonged cessation

JPGN Reports, EarlyView.
Abstract Food protein‐induced enterocolitis syndrome (FPIES) is a nonimmunoglobulin E (IgE)‐mediated food allergy. Most patients with solid FPIES experience a period of asymptomatic intake of the causative foods before onset. This study aimed to elucidate the pattern of egg yolk (EY) ingestion that triggers FPIES.

Egg Yolk Protective Effect in Boar Spermatozoa Cooled at 5ºC

Scientific Papers Animal Science and Biotechnologies, 2023
Nowadays, many boar reproduction researches are directed to improve extenders and to increase cold shock protection of semen. Little research is focused on the influence of egg yolk combined with alternative cold shock protective media.
