Cryopreservation of spermatozoa is a pivotal tool in assisted reproduction, and studies aiming to establish optimal freezing/thawing protocols are essential enhance sperm survival. The objectives the present study were (1) compare cryoprotective efficiency three different glycerol concentrations (3%, 5%, 7%) on basis post-thaw quality (2) investigate whether incidence morphologically abnormal fresh samples related cryodamage sensitivity. Semen was collected from six tomcats using an...
Autophagy is a lysosomal degradation pathway that removes protein aggregates and damaged organelles maintaining cellular integrity. It seems to be essential for cell survival during stress, starvation, hypoxia, consequently the placenta implantation development. Preeclampsia (PE) multisystemic disorder characterized by onset of hypertension associated or not with proteinuria other maternal complications. Considering play an important role in pathogenesis PE, objective present study was...
Equine infectious anemia virus (EIAV) is a persistent lentivirus that causes equine (EIA). In Brazil, EIAV endemic in the Pantanal region, and euthanasia not mandatory this area. All of complete genomic sequences from field viruses are North America, Asia, Europe, only proviral available. Sequences Brazilian currently available for gag LTR regions. Thus, present study aimed first time to sequence entire RNA naturally infected horses an area Brazil. plasma was used next-generation sequencing...
The occurrence of a high incidence sperm tail defects in male domestic cat resembling the known 'Dag-like' defect is reported. Sperm analyses were performed ejaculated samples collected by an artificial vagina and testicular epididymal cells after castration. following alterations observed using transmission electron microscope: heavily coiled tails containing several axonemal units enclosed same common cell membrane; aberrations main structure; swollen unevenly distributed mitochondria...
In mammalian species, oocyte activation is initiated by oscillations in the intracellular concentration of free calcium ([Ca(2+)]i), which are also essential to allow embryonic development. To date, evidence supporting hypothesis that a sperm factor responsible for initiating has been presented various species. Among possible candidates be active novel sperm-specific phospholipase C ζ (PLCζ), besides its testis-specific expression capable [Ca(2+)]i oscillations. this study, we investigated...
Considering the efficiency of steroidal anti-inflammatory drugs (SAIDs) in immunomodulation breeding-induced endometritis and possibility using these by intrauterine route instead parenteral application, present study aimed at evaluating effect SAIDs added to semen extender on equine sperm viability fertility. In experiment 1, 15 were individually a skim milk-based and, based results motility, dexamethasone was drug choice for subsequent trials. The fresh 24-hour cooled investigated 2. 3,...
Testosterone is a steroid hormone known to be critically involved in the initiation and maintenance of spermatogenesis. For this reason, objective study was investigate concentration testosterone blood seminal plasma their relationship sperm count domestic cat. Six adult mixed-breed male cats, exposed more than 12h natural light per day were used as semen donors. Semen collection performed during breeding season (October December) with at least 2-d interval all tomcats submitted on same day....
Post-breeding endometritis in mares is related to inflammatory process, which stimulated by the presence of sperm cells inside uterus. However, when this response takes persistent form, it becomes one most frequent causes sub-fertility and form usually occurs older than 14 years age. With efficiency shown nonsteroidal anti-inflammatory drugs immunomodulation uterine inflammation possibility increasing productivity these affected animals, study aimed evaluate impact dexamethasone systemically...
