A regularized MANOVA test for semicontinuous high-dimensional data [PDF]
arXivWe propose a MANOVA test for semicontinuous data that is applicable also when the dimensionality exceeds the sample size. The test statistic is obtained as a likelihood ratio, where numerator and denominator are computed at the maxima of penalized likelihood functions under each hypothesis.

Estrogen-dependent uterine secretion of osteopontin activates blastocyst adhesion competence. [PDF]
PLoS ONE, 2012 Embryo implantation is a highly orchestrated process that involves blastocyst-uterine interactions. This process is confined to a defined interval during gestation referred to as the "window of embryo implantation receptivity".

Frozen blastocysts: Assessing the importance of day 5/day 6 blastocysts or blastocyst quality
Experimental and Therapeutic Medicine, 2022 The aim of the present study was to analyze the high-quality blastocyst (HB) rate in all embryo frozen cycles and investigate the pregnancy outcomes for day 5/day 6 (D5/D6) blastocysts with respect to the blastocyst quality in programmed single vitrified-warmed blastocyst transfer (SVBT).

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage. [PDF]
, 2014 Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies ...

Image Segmentation of Zona-Ablated Human Blastocysts [PDF]
IEEE 13th International Conference on Nano/Molecular Medicine &
Engineering (NANOMED), Gwangju, Korea (South), 2019, pp. 208-213, 2020 Automating human preimplantation embryo grading offers the potential for higher success rates with in vitro fertilization (IVF) by providing new quantitative and objective measures of embryo quality. Current IVF procedures typically use only qualitative manual grading, which is limited in the identification of genetically abnormal embryos.

Impact of Plasmatic Progesterone on the Day of Frozen Embryo Transfer in Hormone-induced Cycles
Revista Brasileira de Ginecologia e Obstetrícia, 2021 Objective To establish a relationship between serum progesterone values on the day of frozen blastocyst transfer in hormone-replaced cycles with the probability of pregnancy, miscarriage or delivery.

Morphogenesis of the mammalian blastocyst [PDF]
Molecular and Cellular Endocrinology, 2008 The first 4 days of mouse pre-implantation development are characterized by a period of segmentation, including morphogenetic events that are required for the divergence of embryonic and extra-embryonic lineages. These extra-embryonic tissues are essential for the implantation into the maternal uterus and for the development of the foetus.
