Background Traditionally, embryo incubation and assessment daily has been under a light microscope, these observations are inevitably restricted to specific times and considering that the development of the embryo is a dynamic process, several critical stages in between observations may go unnoticed. For this reason, the new technologies, time lapse monitoring, have focused on the research for ...

background: embryo selection is a vital part of in vitro fertilization (ivf) programs, with morphology-based grading systems having been widely used for decades. time-lapse imaging combined with embryo morph kinetics may proffer a non-invasive means for improving embryo selection. we report the first ongoing and chemical pregnancies using time-lapse embryo scope to select best embryos for trans...

Precise protein structure determination provides significant information on life science research, although high-quality crystals are not easily obtained. We developed a system for producing high-quality protein crystals with high throughput. Using this system, gravity-controlled crystallization are made possible by a magnetic microgravity environment. In addition, in-situ and real-time observa...

OBJECTIVE This study aimed to correlate male age with embryo morphokinetic parameters on D3 considering the timing and the exact moment of embryo cleavage. METHODS Time-lapse imaging was used to produce an ideal cleavage curve for the embryos analyzed. The percentage of embryos under the curve was analyzed and correlated with male age. RESULTS 32.6% of the embryos from patients aged 28-33 y...

Time-lapse imaging of embryos has been widely introduced to fertility laboratories worldwide with the aim of identifying the best quality embryos to transfer that will ultimately improve IVF success rates. In this opinion paper, we explore the lack of evidence of benefit of this novel intervention, analyse the methodological flaws of current studies, offer ideal study designs that assess the va...

Smoking cessation is a process that unfolds over time and is characterized by intermittent lapses. We used parametric recurrent event survival analyses to better understand the dynamic relationship between a set of Abstinence Violation Effect (AVE, Marlatt & Gordon, 1985) responses to lapsing and subsequent lapse-relapse progression. Participants were 203 smokers who achieved abstinence and res...
