O-077. Mosaicism evaluation by FISH in normally fertilized and normally developing human embryos

Microarray analysis reveals abnormal chromosomal complements in over 70% of 14 normally developing human embryos.

STUDY QUESTION What are the aneuploidy rates and incidence of mosaicism in good-quality human preimplantation embryos. SUMMARY ANSWER High-level mosaicism and structural aberrations are not restricted to arrested or poorly developing embryos but are also common in good-quality IVF embryos. WHAT IS KNOWN ALREADY Humans, compared with other mammals, have a poor fertility rate, and even IVF tr...

Relationship between rapid naming, phonological awareness and spelling in Farsi normally developing children

Introduction: The aim of the present study was to investigate relationship among phonological awareness, rapid naming and spelling in normally developing Farsi speaking children. Materials and Methods: In this description- analytical cross sectional study 30 normally developing students randomly selected from Tehran (Iran). The students performed Nama reading and dyslexia, rapid automatized nam...

Bio-electrosprayed multicellular zebrafish embryos are viable and develop normally.

Bio-electrosprays are rapidly emerging as a viable protocol for directly engineering living cells. This communication reports the bio-electrospraying of multicellular organisms, namely zebrafish embryos. The results demonstrate that the bio-electrospray protocol fails to induce any embryological perturbations. In addition to analysing overall embryo morphology, we use transgenic embryos that ex...

Auditory and visual novelty processing in normally-developing Kenyan children

OBJECTIVE The aim of this study was to describe the normative development of the electrophysiological response to auditory and visual novelty in children living in rural Kenya. METHODS We examined event-related potentials (ERPs) elicited by novel auditory and visual stimuli in 178 normally-developing children aged 4-12 years (86 boys, mean 6.7 years, SD 1.8 years and 92 girls, mean 6.6 years,...
