Genome-wide association study and mouse expression data identify a highly conserved 32 kb intergenic region between WNT3 and WNT9b as possible suscep…

Item does not contain fulltext Bladder exstrophy-epispadias complex (BEEC), the severe end of the urorectal malformation spectrum, has a profound impact on continence as well as sexual and renal functions. It is widely accepted that for the majority of cases the genetic basis appears to be multifactorial. Here, we report the first study which utilizes genome-wide association methods to analyze a cohort comprising patients presenting the most common BEEC form, classic bladder exstrophy (CBE), to identify common variation associated with risk for isolated CBE. We employed discovery and follow-up samples comprising 218 cases/865 controls and 78 trios in total, all of European descent. Our disc…

A time to look back: analysis of morphokinetic characteristics of human embryo development.

2013

Objective To describe the times associated with the morphological changes that occur in the embryo during preimplantation development based on the largest sample size described with time lapse. Design Cohort study. Setting University-affiliated private center. Patient(s) A total of 9,530 embryos from 1,806 intracytoplasmic sperm injection (ICSI) cycles. Intervention(s) None. Main Outcome Measure(s) Using a time-lapse system, embryo images were acquired for at least 68 hours, in some cases reaching 120–130 hours. Embryo cleavage time points up to 8-cell-stage (t2–t8) as well as morulae (tM) and blastocyst formation (tB) were registered in hours after ICSI. Additionally, duration of the cell …

Physiological incongruity of the humero-ulnar joint: a functional principle of optimized stress distribution acting upon articulating surfaces?

1993

Investigations into the distribution of subchondral bone density in the human elbow have suggested that the geometry of the trochlear notch deviates from a perfect fit with the trochlea, and that the load is transmitted ventrally and dorsally rather than through the centre of the humero-ulnar joint. We therefore decided to make a quantitative assessment of the degree of incongruity between the two components in 15 human specimens (age distribution 60 to 93 years) with different types of joint surface. Polyether casts of the joint cavity were prepared under loads of 10, 40, 160 and 640 N. The thickness of the casts was then measured at 50 predetermined points, and an area distribution of the…
