Cryopreservation of spermatozoa plays a significant role in reproductive medicine and fertility preservation. Chicken egg yolk is used as an extender in cryopreservation of human spermatozoa using glycerol egg yolk citrate (GEYC) buffered medium. Even though 50% survival of spermatozoa is generally achieved with this method, the risk of high levels of endotoxins and transmission pathogens from ...
Shell eggs were irradiated and the physico-chemical, and functional properties of egg yolk and white were determined. The color of egg yolk was not affected, but the viscosity of egg white was dramatically lowered and became watery by irradiation. The foam capacity and foam stability of egg white were significantly decreased due to protein oxidation by irradiation. However, the texture characte...
This retrospective study included 133 children aged between 2 and 16 years with elevated serum food-specific immunoglobulin E (IgE), including 59 children clinically diagnosed with atopic dermatitis (AD) and 74 children clinically diagnosed with atopic disease without AD (asthma, allergic rhinitis, or both). Six common serum food-specific IgEs were detected by the Pharmacia ImmunoCAP test, incl...
BACKGROUND Evidence is conflicting as to whether the bioavailability of food folates is influenced by the extent of their conjugation. OBJECTIVE The objective was to compare the bioavailability of 3 representative food folate sources with various degrees of glutamylation-ie, egg yolk, spinach, and yeast, whose polyglutamyl folate content measured 0%, 50%, and 100%, respectively. DESIGN In a...
Current paradigms may substantially underestimate the complexity of reptilian sex determination. In previous work, we have shown that the sex of a hatchling lizard (Bassiana duperreyi, Scincidae) does not depend entirely on its genes (XX versus XY sex chromosomes); instead, low nest temperatures can override genotype to produce XX as well as XY males. Our experimental studies now add a third me...
As with traditional feed grains, the form in which flax seed is fed impacts egg production and hen performance (Choi et al. 1986, Vilarino et al. 1996). Flax seed form also affects the amount of omega-3 polyunsaturated fatty acid (PUFA) incorporated into the egg. Differences in the omega-3 content of eggs from laying hens fed whole versus milled flax seed have been reported, with many researche...
BACKGROUND Intraduodenal bile salts exert negative feedback control on postprandial gall bladder emptying. AIMS We wished to examine whether a similar control mechanism occurs in the fasting state. METHODS Intraduodenal bile salt depletion was achieved by 12 g of cholestyramine. Thereafter, in study A (seven subjects), the effects on gall bladder volume (by ultrasound) and antroduodenal mot...
Background: Intraduodenal bile salts exert negative feedback control on postprandial gall bladder emptying. Aims: We wished to examine whether a similar control mechanism occurs in the fasting state. Methods: Intraduodenal bile salt depletion was achieved by 12 g of cholestyramine. Thereafter, in study A (seven subjects), the effects on gall bladder volume (by ultrasound) and antroduodenal moti...
Direct plating of stool specimens on selective (Clostridium botulinum isolation) and nonselective (egg yolk agar) media was evaluated as an aid in confirming infant botulism. C. botulinum was isolated from 13 of 14 culture-positive specimens with C. botulinum isolation and from 8 of 14 egg yolk agar. No lipase reaction was seen on plates of 31 culture-negative specimens.
Double-yolked (DY) and single-yolked (SY) duck eggs (n = 1318 for both) were candled and weighed on Days (d) 2, 8, 12, 15, 19, 22 and 25 of incubation and yolk/embryo position was recorded on d2, d8 and at post-mortem. From d8 only eggs with live fertile yolk(s) remained in the incubator. On d2, 99.39% of yolks in DY eggs were in the adjacent position and by d8 yolk positions changed to paralle...
