Utilizing a newly released cognitive Polygenic Score (PGS) from Wave IV of Add Health (n = 1,886), structural equation models (SEMs) examining the relationship between PGS and fertility (which is approximately 50% complete in the present sample), employing measures of verbal IQ and educational attainment as potential mediators, were estimated. The results of indirect pathway models revealed tha...
Recurrent pregnancy loss (RPL), recurrent miscarriage or habitual abortion is a multifactorial problem with exasperating and challenging aspects in reproductive medicine. It is defined as two or more consecutive loss of clinical pregnancies. However, the incidence of RPL is less than 5% in pregnant women but its etiology is diverse and varied and also for more than 50% of cases is not clearly d...
In order to test whether prostaglandins (PGs) function as sex pheromones in Hynobius leechii, a salamander that externally fertilizes its eggs, we conducted electro-olfactogram (EOG) studies with 19 PGs, liquid chromatography tandem mass spectrometry (LC-MS/MS) analyses of female and male holding waters, and behavioral tests on selected PGs. Of the 19 PGs tested, only three induced strong EOG r...
In order to clarify the relationship between human papillomavirus (HPV) and a variety of surface epithelial lesions, the presence of papillomavirus genus-specific common structural antigen (pgs-antigen) was immunohistochemically investigated in 256 cases of various tumors and tumorous lesions. The pgs-antigen was demonstrated in cases of verruca vulgaris (11/23 cases), condyloma acuminatum (13/...
Triploidy occurred about 2-3% in human pregnancies and contributed to approximately 15% of chromosomally caused human early miscarriage. It is essential for preimplantation genetic diagnosis and screen to distinct triploidy sensitively. Here, we performed comparative investigations between MALBAC-NGS and MDA-SNP array sensitivity on triploidy detection. Self-correction and reference-correction ...
The importance of Participatory Guarantee Systems (PGS) as an alternative organic certification to third-party (TPC) has grown remarkably in recent years. PGS are argued be less costly than TPC, and adopt the exchange advice knowledge a key element farm inspections. For these reasons, promoted being more accessible for smallholder farmers low-income countries tool supporting conversion standard...
Aneuploidy in pregnancy is known to increase with advanced maternal age (AMA) and associate with repeated implantation failure (RIF), and repeated miscarriage (RM). Preimplantation genetic screening (PGS) has been introduced into clinical practice, screening, and eliminating aneuploidy embryos, which can improve the chance of conceptions for infertility cases with poor prognosis. These patients...
In 2005, the European Society for Human Reproduction and Embryology (ESHRE) PGD Consortium published a set of Guidelines for Best Practice PGD to give information, support and guidance to potential, existing and fledgling PGD programmes. Subsequent years have seen the introduction of new technologies as well as the evolution of current techniques. Additionally, in light of recent advice from ES...
BACKGROUND In both in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), selection of the most competent embryo(s) for transfer is generally based on morphological criteria. However, many women fail to achieve a pregnancy after transfer of good quality embryos. One of the presumed causes is that such morphologically normal embryos show an abnormal number of chromosomes (aneu...
A retrospective review of the American Association for Surgery Trauma PROspective Observational Vascular Injury Treatment (AAST-PROOVIT) registry from November 2013 to January 2019. Of 460 patients 19 institutions, 402 were treated with autologous vein grafts (AVGs) and 58 prosthetic interposition (PGs) (45 polytetrafluorethylene grafts, 5 Dacron, 8 other). The PG group was more severely injure...
