Ultrastructural characteristics of non-matured and in vitro matured oocytes collected from pre-pubertal and adult domestic cat ovaries
(2009-07-01)
The present study describes the ultrastructural characteristics of cat oocytes before maturation and after 12- and 24-h in vitro maturation (IVM). Oocytes were recovered from pre-pubertal and adult queen ovaries after ...

Endothelial and inducible nitric oxide synthases in oocytes of cattle
(ELSEVIER SCIENCE BV, 2009)
Nitric oxide (NO) is a chemical messenger generated by the activity of the nitric oxide synthases (NOS). The NOS/NO system appears to be involved in oocyte maturation, but there are few studies on gene expression and protein ...
Role of arachidonic acid cascade in Rhinella arenarum oocyte maturation
(Cambridge University Press, 2015-08)
There are no studies that document the production of prostaglandins (PGs) or their role in Rhinella arenarum oocyte maturation. In this study, we analysed the effect of arachidonic acid (AA) andprostaglandins (PGs) on ...
Treatment with roscovitine and butyrolactone i prior to in vitro maturation alters blastocyst production
(2019-01-01)
SummaryThis study evaluated the effects of oocyte meiosis inhibitors roscovitine (ROS) and butyrolactone I (BL-I) on in vitro production of bovine embryos. Bovine oocytes were maintained in pre in vitro maturation (pre-IVM) ...
Chronic periodontitis and pre-term labour in Brazilian pregnant women: an association to be analysed

Late seed maturation improves the preservation of seedling emergence during storage in soybean(1)
(Abrates-assoc Brasileira Technologia Sementes, 2018-04-01)
Long-term survival during dry storage or longevity is a pre-requisite to avoid deterioration, leading to loss of vigor. Longevity is routinely evaluated by the ability to germinate after storage. It increases progressively ...
Maternal and neonatal interleukin-1 receptor antagonist genotype and pregnancy outcome in a population with a high rate of pre-term birth
(WILEY-BLACKWELL, 2008)
Problem We evaluated associations between a length polymorphism in intron 2 of the gene coding for IL-1ra (gene symbol IL1RN) and pregnancy outcome in a population with a high rate of preterm birth. Method of study Subjects ...
