Objectives To evaluate the effectiveness of iodine-125 (125I) seed implantation for pancreatic cancer (PC), and preliminarily evaluate the clinical value of a self-developed three-dimensional (3D) visualized seed planning and navigation system in 125I seed implantation for treatment of PC. Patients and methods Our team retrospectively reviewed 25 PC patients who underwent 125I seed implantati...

To optimize success rates of IVF, selection of the most viable embryo(s) for transfer has always been essential, as embryos that are cryopreserved are thought to have a reduced chance of implanting after thawing. Recent developments challenge this concept. Evidence is accumulating that all embryos can now be cryopreserved and transferred in subsequent cycles without impairing pregnancy rates or...

BACKGROUND The aim of this study was to analyse the outcome of closed blastocyst vitrification of embryos biopsied at the cleavage stage. METHODS Vitrification of supernumerary blastocysts was performed using the closed CBS-VIT High Security straws. Warming cycles (n = 100) for patients with preimplantation genetic diagnosis (PGD) and/or aneuploidy screening in the fresh cycle were analysed. ...

background: a major hurdle to improved in vitro fertilization (ivf) success rate is defective endometrial receptivity and implantation. various techniques have been advocated to increase implantation while reducing side effects. currently, embryo transfer (et) is performed blindly without direct visualization. as such, we sought to develop a technique utilizing a flexible minihysteroscope with ...

The aim of this report has been evaluating protamine content and DNA integrity of two patients with globozoospermia undergoing Intra Cytoplasmic Sperm Injection (ICSI). Semen analysis was carried out according to WHO criteria. Protamine deficiency and DNA fragmentation was assessed using Chromomycin A3 and sperm chromatin dispersion assay respectively. ICSI and chemical activation were carried ...

OBJECTIVE To report the outcomes of more than 100 cycles of preimplantation genetic diagnosis for monogenetic diseases. DESIGN Case series. SETTING Tertiary assisted reproductive centre in Hong Kong, where patients needed to pay for the cost of preimplantation genetic diagnosis on top of standard in-vitro fertilisation charges. PATIENTS Patients undergoing preimplantation genetic diagnosi...

BACKGROUND Sacral neuromodulation (SNM) has become an effective method for treating lower urinary tract voiding dysfunction during the past 20 years. Because of the expensive cost, the number of implantable pulse generator (IPG) implantations per year in China is far lower than that in Western developed countries since 2012. This study was to summarize the effects of the appropriate prolonged S...

BACKGROUND There is no doubt that luteal phase support is essential to enhance the reproductive outcome in IVF cycles. In addition to progesterone and human chorionic gonadotropin, several studies have described GnRH agonists as luteal phase support to improve implantation rate, pregnancy rate and live birth rate, whereas other studies showed dissimilar conclusions. All of these studies have be...

Drug-eluting stents (DES) have reduced the rate of repeated revascularization of target lesions. For this reason, DES are considered to be superior to bare-metal stents in reducing the restenosis rate. However, some problems have been reported after implantation of DES. One of them, stent thrombosis, has arisen as a fatal complication. Dual antiplatelet therapy is recommended for at least 12 mo...

The aim of this study was to evaluate the effects of progesterone and ovarian stimulation on the development and implantation rate of mouse embryos. Two-cell embryos were collected from superovulated mice and cultured in the presence of different concentrations of progesterone (0, 5, 10 and 20 ng/ml). Also other mice were rendered pregnant in unstimulated, unstimulated progesterone-injected, su...
