Differential neutrophil gene expression in early bovine pregnancy
Reproductive Biology and Endocrinology - Tập 11 - Trang 1-10 - 2013
In food production animals, especially cattle, the diagnosis of gestation is important because the timing of gestation directly affects the running of farms. Various methods have been used to detect gestation, but none of them are ideal because of problems with the timing of detection or the accuracy, simplicity, or cost of the method. A new method for detecting gestation, which involves assessing...... hiện toàn bộ
Novel bi-allelic MSH4 variants causes meiotic arrest and non-obstructive azoospermia
Reproductive Biology and Endocrinology - Tập 20 - Trang 1-10 - 2022
Non-obstructive azoospermia (NOA) is one of the most severe type in male infertility, and the genetic causes of NOA with meiotic arrest remain elusive. Four Chinese families with NOA participated in the study. We performed whole-exome sequencing (WES) for the four NOA-affected patients in four pedigrees. The candidate causative gene was further verified by Sanger sequencing. Hematoxylin and eosin ...... hiện toàn bộ
Efficient vitrification of mouse embryos using the Kitasato Vitrification System as a novel vitrification device
Reproductive Biology and Endocrinology - Tập 15 - Trang 1-9 - 2017
Currently, the cryopreservation of embryos and oocytes is essential for assisted reproductive technology (ART) laboratories worldwide. This study aimed to evaluate the efficacy of the Kitasato Vitrification System (KVS) as a vitrification device for the cryopreservation of mouse embryos to determine whether this novel device can be adapted to the field of ART. In Experiment 1, blastocysts were vit...... hiện toàn bộ
Conjugated linoleic acid improves oocyte cryosurvival through modulation of the cryoprotectants influx rate
Reproductive Biology and Endocrinology - Tập 13 - Trang 1-8 - 2015
In cryopreservation, oocytes are subjected to extreme hyperosmotic conditions, inducing large volume changes that, along with an abrupt temperature drop, interfere with their developmental competence. Our objectives in this work were to find conditions enabling an increase in oocyte cryosurvival and subsequent development. Abattoir-derived bovine oocytes were cultured without (Control group) or wi...... hiện toàn bộ
Erratum: Divergent activity of the gonadotropin-releasing hormone receptor gene promoter among genetic lines of pigs is partially conferred by nuclear factor (NF)-kB, specificity protein (SP)1-like and GATA-4 binding sites
Reproductive Biology and Endocrinology - Tập 14 - Trang 1-1 - 2016
A comparison of human chorionic gonadotropin and luteinizing hormone releasing hormone on the induction of spermiation and amplexus in the American toad (Anaxyrus americanus)
Reproductive Biology and Endocrinology - Tập 10 - Trang 1-11 - 2012
Captive breeding programs for endangered amphibian species often utilize exogenous hormones for species that are difficult to breed. The purpose of our study was to compare the efficacy of two different hormones at various concentrations on sperm production, quantity and quality over time in order to optimize assisted breeding. Male American toads (Anaxyrus americanus) were divided into three sepa...... hiện toàn bộ
Commentary on two recently published formal guidelines on management of “mosaic” embryos after preimplantation genetic testing for aneuploidy (PGT-A)
Reproductive Biology and Endocrinology - Tập 19 - Trang 1-6 - 2021
Two professional societies recently published opinions on the clinical management of “mosaic” results from preimplantation genetic testing for aneuploidy (PGT-A) in human blastocyst-stage embryos in associations with in vitro fertilization (IVF). We here point out three principal shortcomings: (i) Though a most recent societal opinion states that it should not be understood as an endorsement of th...... hiện toàn bộ
Semaphorin-4D (Sema-4D), the Plexin-B1 ligand, is involved in mouse ovary follicular development
Reproductive Biology and Endocrinology - Tập 5 - Trang 1-8 - 2007
Human Plexin-B1 is expressed in two truncated forms. The long form encodes a trans-membranal protein, while the short form, which is bound to the cell surface and partially secreted, possibly serves as a decoy receptor. Plexin receptors are trans-membrane proteins. The sema domain, found in the extracellular region, is common to all plexins, semaphorins, and the scatter factor receptors and is cru...... hiện toàn bộ
Efficacy of the motile sperm organelle morphology examination (MSOME) in predicting pregnancy after intrauterine insemination
Reproductive Biology and Endocrinology - Tập 9 - Trang 1-9 - 2011
Although the motile sperm organelle morphology examination (MSOME) was developed merely as a selection criterion, its application as a method for classifying sperm morphology may represent an improvement in the evaluation of semen quality. The aim of this study was to determine the prognostic value of normal sperm morphology using MSOME with regard to clinical pregnancy (CP) after intrauterine ins...... hiện toàn bộ
Angiotensin II and angiotensin-(1-7) decrease sFlt1 release in normal but not preeclamptic chorionic villi: an in vitro study
Reproductive Biology and Endocrinology - Tập 8 - Trang 1-10 - 2010
During preeclampsia, placental angiogenesis is impaired. Factors released from the placenta including vascular endothelial growth factor (VEGF), placental growth factor (PLGF), soluble VEGF receptor 1 (sFlt1), and soluble endoglin (sEng) are regulatory molecules of placental development and function. While the renin angiotensin system has been shown to regulate angiogenic factors in other research...... hiện toàn bộ
