Vascular complications are serious problems after kidney transplantation. An aneurysm or rupture in a graft artery is a rare but potentially devastating complication, which may lead to renal function impairment, graft loss, or even death. In this paper, we present two rare vascular complications in the early postoperative course after renal transplantation from the same deceased donor. In the first case, a 49-year-old woman who had spontaneous graft arterial rupture 13 days after kidney transplantation presented with sudden distension in the right lower abdomen. In the second case, a 56-year-old woman recipient with a graft renal arterial pseudoaneurysm presented with decreased urine output and deteriorating renal function 32 days after transplantation. Immediate surgical repair was performed, and fibrin sealant was applied to strengthen the fragile renal arterial wall. Although the function of both graft kidneys recovered well after surgery, the first graft kidney was removed 2 months later because of repeated fungal and bacterial infections. Aggressive surgical reconstruction may preserve graft kidneys in patients with vascular complications after kidney transplantation, but recovery of the graft condition remains a demanding challenge in renal transplantation.

GmFT2a is a key gene in photoperiodic pathway of soybean. However, the underlying molecular mechanism of GmFT2a expression is not clear. In this study, a photoperiod-sensitive soybean cultivar Zigongdongdou and insensitive cultivar Heihe 27 were used as materials to compare the GmFT2a promoter sequences. It revealed that there were 2 insertion/deletion (InDel) fragments, T1 and T2, which contained light reaction elements in the GmFT2a promoter of Zigongdongdou. However, the same fragments were not in that of Heihe 27. The bait constructs were prepared according to the sequences of light reaction elements of I-box and SP1 to screen cDNA library of Heihe 27 leaves, and a MYB transcription factor bound with T1 was isolated with the yeast one-hybrid system. The obtaining of the MYB transcription factor provided a favorable clue for further study of the molecular mechanism GmFT2a expression regulation. [ABSTRACT FROM AUTHOR]

Molecular breeding is the main force driving the global soybean production development, and has become the core technology in competition of the international soybean seed industry. This review summarized the progress in molecular breeding of soybean made in 2012 and 2013. In these two years, there was rapid development in research of functional genomics due to the application of high-throughput technologies. New genes involved in flowering, yield, nodulation, resistance and tolerances had been isolated from soybean. In the field of molecular mapping, some new markers or QTLs had been identified, and the integration between conventional markers and novel technologies have been enhanced. Soybean genetic transformation system had been further optimized and some genes have been transformed into soybean to identify their functions. New individual or stacked transgenic events conferring insect resistance and herbicide resistance had been approved for import as food, feed or commercial planting in many countries. The paper also prospected the development of soybean molecular breeding in the near future in this article. [ABSTRACT FROM AUTHOR]
