Abstract Study question Limited studies have explored the correlation between pronuclear characteristics, developmental potential, and genetic constitution of mono-pronuclear (1PN) zygotes. Summary answer Those 1PN zygotes developed into blastocysts unique characteristics significantly higher rate diploidy euploidy in comparison with arrested embryos. What is known already It has been reported ...

We present the ?3-coordination of 2-phosphaethynthiolate anion in complex (PN)2La(SCP) (2) [PN=N-(2-(diisopropylphosphanyl)-4-methylphenyl)-2,4,6-trimethylanilide)]. Structural comparison with dinuclear thiocyanate-bridged (PN)2La(?-1,3-SCN)2La(PN)2 (3) and azide-bridged (PN)2La(?-1,3-N3)2La(PN)2 (4) complexes indicates that [SCP]? coordination mode is mainly governed by electronic, rather than...

Our aim was to investigate the effects of modifying the carbohydrate-to-lipid ratio of parenteral nutrition (PN) on body composition and the anabolic actions of insulin-like growth factor I (IGF-I) and growth hormone (GH). Adolescent male Sprague-Dawley rats were randomized to receive 7 days of GH, IGF-I (3.5 mg. kg(-1). day(-1) for both) or placebo while receiving high-carbohydrate PN (CHO-PN)...

We prove that lim inf n→∞ pn+1 − pn √ log pn(log log pn) < ∞, where pn denotes the n prime. Since on average pn+1 −pn is asymptotically log pn, this shows that we can always find pairs of primes much closer together than the average. We actually prove a more general result concerning the set of values taken on by the differences p− p between primes which includes the small gap result above.
