Article Synopsis
  • The study focuses on the cryopreservation of testicular tissue and sperm in bulls, examining how these processes impact sperm quality and cell viability, as well as the expression of the PARP-1 gene.
  • Testes were collected from 20 bulls, and sperm was frozen using liquid nitrogen, with testicular tissue treated with cryoprotectants like DMSO and EG before freezing.

Article Synopsis
  • The study evaluated how Biodentine and NeoPutty reacted in terms of color stability and solubility when exposed to various irrigation solutions like EDTA and chlorhexidine.
  • Results showed that Biodentine changed color more than NeoPutty, especially when immersed in chlorhexidine and sodium hypochlorite, while both materials had similar solubility levels.
  • The findings suggest that NeoPutty is better for aesthetic applications, and using HEDP as an irrigant is beneficial due to its lower impact on solubility and discoloration.

In this study we used ivabradine (IVA), a hyperpolarization-activated cyclic nucleotide-gated (HCN) channel blocker, to identify its effect on spike-wave discharges (SWDs); and aimed to determine the role of IVA on the effects of T-type calcium channel blocker NNC 55-0396, GABA receptor agonist muscimol and antagonist bicuculline in male WAG/Rij rats. After tripolar electrodes for electrocorticogram (ECoG) recordings were placed on the WAG/Rij rats' skulls, 5, 10, and 20 mg/kg IVA were intraperitoneally administered for 7 consecutive days and ECoG recordings were obtained on days 0, 3, 6, and 7 for three hours before and after injections. While acute injection of 5, 10, and 20 mg/kg IVA did not affect the total number and the mean duration of SWDs, subacute administration (7 days) of IVA decreased the SWDs parameters 24 hours after the 7 injection.
