There are both fundamental and practical motivations for studying whether quantum entanglement can exist in macroscopic systems. However, multiparty entanglement is generally fragile and difficult to quantify. Dicke states are multiparty entangled states where a single excitation is delocalized over many systems. Building on previous work on quantum memories for photons, we create a Dicke state in a solid by storing a single photon in a crystal that contains many large atomic ensembles with distinct resonance frequencies. The photon is re-emitted at a well-defined time due to an interference effect analogous to multi-slit diffraction. We derive a lower bound for the number of entangled ensembles based on the contrast of the interference and the single-photon character of the input, and we experimentally demonstrate entanglement between over two hundred ensembles, each containing a billion atoms. We also illustrate the fact that each individual ensemble contains further entanglement. [ABSTRACT FROM AUTHOR]

Unilateral renal agenesis is defined as the absence of one kidney with visible bladder and normal amniotic fluid. The objective was to describe the association between unilateral, bilateral renal agenesis, and ectopic kidney with other major abnormalities or genetic alterations. A review of the ultrasound database identified fetuses with unilateral, bilateral renal agenesis and ectopic kidney from 2011 to 2020. [Extracted from the article]

First trimester screening and non-invasive prenatal testing was low risk. Holt-Oram syndrome (HOS) is a rare autosomal dominant disorder characterised by skeletal malformations of the upper limbs and congenital heart disease. Fetal autopsy confirmed ultrasound diagnosis of phocomelia and oligodactyly (presence of three fingers on both hands) associated with complex heart disease characterised by: right atrium enlargement, ostium secundum atrial septal defect, single atrioventricular valve (right side), hypoplastic left heart and ventricular septal defect showing a continuity fault in the aortic valve.
