As discussed above, a substitute for Scarb1 attenuated models could be the Pdzk1−/− mouse models, since Pdzk1−/− mice have a 95% liver specific reduction in SCARB1 protein levels and do not have fertility abnormalities.
4 Some of the effects of welding on health include photokeratitis or arc eye, metal fume fever, decrease in lung function, pneumoconiosis, asthma, photodermatitis and fertility abnormalities.
They are inter-fertile, but inter-specific crosses aimed at recombination of of genes underlying their complementary agronomic performance have generally resulted in difficulties such as reduced fertility, cytological abnormalities and distorted segregation in the F 2 generation.
Using extant dec-1 mutations in conjunction with genetically engineered dec-1 transgenes, we show that, although all three dec-1 proproteins, fc106, fc125, and fc177, are required for female fertility, gross morphological abnormalities in the eggshell are observed only in the absence of fc177.
The fungicide vinclozolin induces fertility problems and abnormalities in rats for at least four subsequent generations.
The other stallions had 65 75% morphologically normal spermatozoa with a low incidence of individual abnormalities: fertility rates varied from 50 to 78%.
The case for understanding the impact of EDCs on reproduction is enlightening because of the long-standing literature for diminished fertility and reproductive abnormalities in wildlife, laboratory animals, and human populations.
This is another wild diploid potato species of hybrid origin, as supported by the results of Raimondi et al. [ 3] and the low pollen fertility and meiotic abnormalities reported herein.
The co-existence of a systemic metabolic disorder, associated malformations or dysmorphic features would lower the threshold for investigation as would a family history of consanguinity, stillbirths, multiple miscarriages, fertility problems, genital abnormalities, hernias, delayed puberty, genital surgery, unexplained deaths and the need for steroid replacement.
Models in other species also implicate telomere-independent dysfunction associated with dyskerin: partial loss-of-function mutations in the Drosophila DKC1 homologue gene mfl result in reduced body size, developmental delay, reduced female fertility and morphological abnormalities in the ovaries characteristic of apoptosis [59].
The UI group included women that were unable to conceive after 2 years with routine investigations of fertility showing no abnormality.
