: The avian eggshell membrane (ESM) is stabilized by extensive cross-linkages, making the identification of its protein constituents technically challenging. Herein, we applied various extraction/solubilization conditions followed by proteomic analysis to characterize the protein constituents of ESM derived from the unfertilized chicken eggs. The egg white and eggshell proteomes (including previous published work) were determined and compared to ESM to identify proteins that are relatively or highly specific to ESM...

Methylmercury (MeHg) readily crosses the blood brain barrier and is a known neuro-toxicant. MeHg accumulation in the brain causes histopathological alterations, neurobehavioral changes, and impairments to cognitive motor functions in mammalian models. However, in birds the neurotoxic effects of MeHg on the developing pre-hatching brain and consequent behavioral alterations in adult birds have not received much attention. Moreover, passerine birds are poorly represented in MeHg neurotoxicology studies in comparison to other avian orders...

The presence of microorganisms on the eggshell surface is a factor of consideration in determining egg quality. These microorganisms can contribute to egg spoilage and can infect the egg. In this study, 18 morphotypes of microorganisms were isolated from eggshells. Morphological, biochemical, physiological and molecular analyses were used to identify these morphotypes into 7 species; Bacillus drentensis, Staphylococcus arlettae, Stap. cohnii, Stap. kloosii, Stap. saprophyticus, Stap. sciuri and Stap. xylosus...

Thyroid hormone (TH) disrupting compounds are potentially important environmental contaminants due to their possible adverse neurological and developmental effects on both humans and wildlife. Currently, the most successful bio-analytical method to detect and evaluate TH disruptors, which target the plasma transport of TH in environmental samples, is the radio-ligand thyroxine-transthyretin (T4-TTR) binding assay. Yet, costly materials and tedious handling procedures prevent the use of this assay in high throughput analysis that is nowadays urgently demanded in environmental quality assessment...

Aphelinus asychis Walker (Hymenoptera: Aphelinidae) is a solitary koinobiont endoparasitoid, which parasitizes the green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae). Host discrimination is the ability of a parasitoid to distinguish between unparasitized and parasitized hosts, so parasitoids can avoid wasting eggs and time. We determined the influence of host density (5, 10, 15, 20, and 25 aphids per experienced parasitoid during a 24-h period) on egg distribution, and tested the effects of different time intervals (0, 24, 48, and 72 h) between successive ovipositions on host discrimination between unparasitized and self- or conspecific-parasitized aphids...

Resource allocation to reproduction is a primary physiological concern for individuals, and can vary with age, environment, or a combination of both factors. In this study we quantified the impact of environment and individual age on the reproductive output of female oysters Crassostrea virginica. We determined the relative fecundity, egg total lipid content, and overall and omega-3/omega-6 (ω3/ω6) fatty acid signatures (FAS) of eggs spawned by female oysters over a 2-year period (n = 32 and n = 64). Variation was quantified spatially and ontogenetically by sampling young and old oyster populations from two rivers in Chesapeake Bay, totaling four collection sites...

Optimizing cryopreservation protocols for nondomestic felids contributes to the successful development of assisted reproduction techniques and genetic resource banking. In this study, we describe a simple cryopreservation procedure for African lion (Panthera leo) ejaculates, which was tested with different packaging options and different sperm numbers per dose. By applying urethral catheterization and electroejaculation, 17 ejaculates with greater than 20% motile and greater than 5% progressively motile sperm were collected...

This study was designed to investigate the effects of an equilibration period up to 96 hours and three extenders (AndroMed, OPTIXcell, and Triladyl) on the quality of cryopreserved bull semen and to evaluate, whether an extension of the equilibration time to 72 hours does affect fertility in the field. One ejaculate of 17 bulls was collected and divided into three equal aliquots and diluted, respectively, with the three extenders. Each aliquot was again divided into five parts and equilibrated for 4, 24, 48, 72, and 96 hours before freezing in an automatic freezer...

The cryopreservation of germ cells is a major tool for the propagation of animals with desired genetic traits. Although cryopreservation of spermatozoa in some animals is effective, its effectiveness is variable. For example, cryopreservation efficiency of buffalo bull spermatozoa remains very poor. In this study, we evaluated sperm DNA damage and ultrastructure in buffalo bull spermatozoa vitrified in the presence or absence of cholesterol-loaded cyclodextrins (CLC). Our results showed that cryopreserved buffalo spermatozoa had elevated levels of deteriorated plasma and mitochondrial membranes, which are the likely causes of DNA damage after vitrification...

INTRODUCTION: The influence of vowels on the frequency region where registration events in male voices usually occur (passaggio) has not yet been clarified. Particularly, for tenors who frequently have to sing across the passaggio, it might be assumed that the vowel quality has an influence on the stability of phonation. METHODS: In this investigation, six professionally trained Western classical tenors performed a glide from A3 (220 Hz) to A4 (440 Hz) and were recorded using high-speed videoendoscopy at 20,000 fps via transnasal flexible endoscopy...

Over the past two decades we have been debating the question of whether the age of commencement of complementary feeding affects the risk of developing food allergy. We ate up the notion that delayed introduction of more allergenic foods in early childhood, would help overcome the increasing rates of food allergy, then we promptly spat it out again despite limited evidence. Recently high-quality randomised controlled trial evidence has given us the confidence to swallow the concept that allergenic foods, like egg and peanut, should be given to infants...

BACKGROUND: Celiac disease (CD) is a gluten-triggered autoimmune disorder of the small intestine. A lifelong gluten-free diet (GFD) is the only approved treatment; however, strict adherence is difficult and many suffer from inadvertent gluten exposure. Oral egg yolk anti-gliadin antibody (AGY) is a novel treatment to neutralize gluten and may improve the efficacy of the GFD. AIMS: To determine the safety, tolerability, and potential efficacy of AGY in patients with CD...

The possibility of complete replacement of egg proteins with whey protein concentrate (WPC) and improvement in quality by different emulsifiers was evaluated. Three emulsifiers, including polyglycerol ester (PGE), distilled mono glyceride (DMG) and lecithin were used to bake eggless cakes, containing 8% (w/w) WPC. The response surface analysis was applied to study the effect of emulsifiers on the eggless cake properties. The emulsifiers, individually and interactively, improved the properties of the eggless cakes significantly...
