Cryopreservation of boar semen is continually researched in reproductive technologies and genetic resource banking in breed conservation. For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of spermatozoa indicates active metabolism, membrane integrity and fertilizing capacity. Recently, polymorphisms reported to be significant association with sperm MOT. This study was conducted to evaluate the SNP in the coding region of ESR1 (g.672C>T inexon 1) as a positional controlling for motility and kinematic characteristics of post-thawed boar semen. To results,The g.672C>T was significantly associated with frozen semen motility and kinematic characteristics. g.158 T>C SNP was high significantly associated with MOT, VCL, VSL and VAP Also, the SNP was low significantly associated with ALH.Therefore, we suggest that theSNP in the coding region of ESR1 (g.672C>T in exon 1) may be used as a molecular marker for Duroc boar Post-thawed semen quality.

Estrogen receptor 2 (ESR2) is involved in oestrogen-related apoptosis in cell cycle spermatogenesis but their effects have not yet confirmed in pig. Therefore, this study was performed to investigatetheir association with semen motility and kinematic characteristics. DNA samples from 126 Duroc pigs with records of sperm motility and kinematic characteristics [Total motile spermatozoa (MOT), Curvilinear velocity(VCL), Straight-line velocity(VSL), the ratio between VSL and VCL(LIN), Amplitude of Lateral Head displacement(ALH)] were used in present study. A single nucleotide polymorphism (g.35547A>G) was associated with MOT, VCL, VAP and ALH in Duroc population (p < 0.05). Therefore, we suggest that the porcine ESR2 may be used as a molecular marker for Duroc boar semen quality, although its functional effect was not clear yet. These results will improve the understanding of the functions of the ESR2 in spermatogenesis within the reproductive tracts, and will shed light on ESR2 as a candidate gene in the selection of good sperm quality boars.

Atrial fibrillation is the most common cardiac arrhythmia, and electrical cardioversion for atrial fibrillation contributes to the formation of systemic thromboembolism. In particular, the increase in the occurrence of thromboembolic events is associated with postcardioversion atrial and atrial appendage "stunning". Most thromboembolic events after cardioversion were found in the cerebral artery. In this case, the patient had a thromboembolism in the brachial artery region, which has not been reported in literature reviews. We describe the first case of brachial arterial thromboembolism which occurred 3 days after cardioversion of atrial fibrillation, and was completely resolved by thrombolytic therapy.
