Prematuration of bovine oocytes with butyrolactone I reversibly arrests meiosis without increasing meiotic abnormalities after in vitro maturation
(ELSEVIER IRELAND LTD, 2009)
Objectives: Asynchrony between nuclear and cytoplasmic maturation, and possibly damage to the oocyte meiotic spindle, limits the application of in vitro maturation (IVM) in assisted reproduction. Several studies have ...
The p75(NTR) neurotrophin receptor is required to organize the mature neuromuscular synapse by regulating synaptic vesicle availability
(2019)
The coordinated movement of organisms relies on efficient nerve-muscle communication at the neuromuscular junction. After peripheral nerve injury or neurodegeneration, motor neurons and Schwann cells increase the expression ...
Ultrastructural and biochemical evidence for the presence of mature steroidogenic acute regulatory protein (StAR) in the cytoplasm of human luteal cells
(ELSEVIER IRELAND LTD, 2005-10-20)
The distribution of the steroidogenic acute regulatory protein (StAR) inside thecal and granulosa-lutein cells of human corpus luteum 9 (CL) was assessed by immunoelectron microscopy. We found greater levels of StAR ...
THE HYPOPHYSEAL-TESTICULAR AXIS AND SEX ACCESSORY-GLANDS FOLLOWING CHEMICAL SYMPATHECTOMY WITH GUANETHIDINE OF PRE-PUBERTAL TO MATURE RATS

Nop53p interacts with 5.8S rRNA co-transcriptionally, and regulates processing of pre-rRNA by the exosome
(WILEY-BLACKWELL, 2008)
In eukaryotes, pre-rRNA processing depends on a large number of nonribosomal trans-acting factors that form intriguingly organized complexes. One of the early stages of pre-rRNA processing includes formation of the two ...
Physiological parameters related to oocyte nuclear differentiation for the improvement of IVM/IVF outcomes in women and cattle
(2021-01-01)
In vitro maturation (IVM) has been applied in numerous different contexts and strategies in humans and animals, but in both cases it represents a challenge still far from being overcome. Despite the large dataset produced ...
Estudo crítico da avaliação da maturidade fetal pela citologia do líquido âmnico: comparação com outros métodos
(Faculdade de Saúde Pública da Universidade de São Paulo, 1975-09-01)
Through amniocentesis carried ou in 90 high-risk pregnant women a critical study of the citology of the amniotic fluid by the Nile-blue sulphate method was undertaken. The results were compared with those obtained by using ...
Characterization and control of oocyte large-scale chromatin configuration in different cattle breeds
(Elsevier B.V., 2020-01-01)
Differences in reproductive physiology between cattle breeds may help to explain distinct responses to assisted reproductive techniques and to define breed-specific protocols with improved efficiency. Germinal vesicle (GV) ...
Comparative reproductive biology of pre-, imaginal, and neotenic castes of the Asian termite Coptotermes gestroi (Blattaria, Isoptera, Rhinotermitidae)
(Cambridge Univ Press, 2022-05-20)
The Asian subterranean termite Coptotermes gestroi is a worldwide structural pest, although its reproductive biology has been poorly investigated due to a cryptic habit and occurrence of polycalic nests. In this study, we ...
