Androgens are essential for epithelial cell recovery after efferent duct ligation in the initial segment of the mouse epididymis†
- Biology, MedicineBiology of Reproduction
BCs are the first to show recovery after EDL, followed by PCs; androgen stimulation during the peripubertal and postpubertal periods is essential for epithelial repair after injury in the mouse epididymis.
Genomic-Morphogenetic Correlations and Evolutionary Trajectories of Bilateria
- BiologyPaleontological Journal
This work examines a correlation node that includes various types of organization of clustered (initially) Hox genes, early embryogenesis type, cellular developmental resources, thereby determining alternative evolutionary trajectories of various Bilateria taxa.
Embryonic/fetal mortality and intrauterine growth restriction is not exclusive to the CBA/J sub-strain in the CBA × DBA model
- Medicine, BiologyScientific reports
The embryonic/fetal mortality and IUGR phenotype is not exclusive to CBA/J female mouse, and CBA-CaH females can be substituted to provide a model for the assessment of novel therapeutics.
Modification of Gene Expression of Connexins in the Rat Corpus Epididymis by Estradiol Benzoate or Flutamide Exposure at the Early Neonatal Age
- Biology, MedicineDevelopment & reproduction
Findings imply that expression of most Cx isoforms present in the corpus epididymis would be transcriptionally regulated by actions of androgen and/or estrogen during postnatal period.
Aberrant Expression of Connexin Isoforms in the Corpus Epididymis of the Adult Rat by Exposure to Estradiol Benzoate or Flutamide at the Weaning Age
- BiologyDevelopment & reproduction
It is demonstrated that exposure to steroidal compounds at the early developmental age alters expression of Cx isoforms in the adult corpus epididymis.

The Role of Leukemia Inhibitory Factor (LIF) and Other Cytokines in Regulating Implantation in Mammals
- BiologyAnnals of the New York Academy of Sciences
It has long been recognized that the cells that comprise the endometrium of the uterus, the glandular and luminal epithelium, the stroma and hemopoietic cells, undergo a well described series of proliferation and differentiative changes in anticipation of implantation.
Relation between semen quality and fertility: a population-based study of 430 first-pregnancy planners
- MedicineThe Lancet
5-methylcytosine-DNA glycosylase activity is present in a cloned G/T mismatch DNA glycosylase associated with the chicken embryo DNA demethylation complex.
- BiologyProceedings of the National Academy of Sciences of the United States of America
Deletion mutations indicate that G/T mismatch and 5-MCDG activities share the same areas of the N- and C-terminal parts of the protein.
From egg to embryo: a peripatetic journey.
This review will briefly highlight the topics that were presented during the Biennial Joint Meeting of the UK Fertility Societies at Warwick University in April 2005.
Air pollution and mutations in the germline: are humans at risk?
- Biology, Environmental ScienceHuman Genetics
Research should be primarily focused upon the direct measurement of mutation frequencies at repetitive DNA loci in human male germ cells as a function of air pollution exposure, large-scale epidemiology studies of inherited disorders and tandem-repeat associated genetic conditions and air pollution, and the characterization of mutational mechanisms at hypervariable tandem- repeat loci.
Sperm DNA integrity assessment in prediction of assisted reproduction technology outcome.
- MedicineHuman reproduction
DFI can be used as an independent predictor of fertility in couples undergoing IUI and all infertile men should be tested with SCSA as a supplement to the standard semen analysis, when DFI exceeds 30%, ICSI should be the method of choice.
Utility of the sperm chromatin structure assay as a diagnostic and prognostic tool in the human fertility clinic.
- BiologyHuman reproduction
Based on logistic regression, spermatozoa with denatured DNA (cells outside the main population, COMP alpha t) were the best predictor for whether a couple would not achieve pregnancy.
“Physiologic ICSI”: Hyaluronic acid (HA) favors selection of spermatozoa without DNA fragmentation and with normal nucleus, resulting in improvement of embryo quality
A2A adenosine receptor stimulation enhances arginase I expression in macrophages resulting in a phenotypically unique macrophage
Background. Macrophages traditionally are grouped into two distinct categories, classically (exposed to LPS or Th1 cytokines) or alternatively (exposed to Th2 cytokines) activated macrophages.…
