Poly(methyl methacrylate) refractive intracorneal ring segments (ICRS) can be removed for a refractive miscorrection or for early complications after implantation. We report the first case of a woman who experienced anterior stromal necrosis 5 years after an ICRS surgical procedure.

Background: Preterm birth (< 37 weeks' gestation) alters cerebrovascular development due to the premature transition from a foetal to postnatal circulatory system, with potential implications for future cerebrovascular health. This study aims to explore potential differences in the Circle of Willis (CoW), a key arterial ring that perfuses the brain, of healthy adults born preterm.
Methods: A total of 255 participants (108 preterm, 147 full-term) were included in the analysis.
In this paper we propose an information encoding method based on a segmented vortex beam. The segmented vortex beam with a single uniform-intensity ring and a combination of multiple topological charges is designed for information encoding. The radius of the beam can be designed to be arbitrary, with multiple orbital angular momentum states superimposed along the ring.

The introgression of heterologous genomes through interspecific hybridization offers a great opportunity to expand the gene pool of crops, thereby broadening the traits that can be targeted for improvement. The introgression of C genomic regions carrying desirable traits from (AACC) into the diploid (AA) via homoeologous recombination (HR) has been commonly used. However, the precise identification of HR sites remains a significant challenge, limiting the practical application of genome introgression via HR in breeding programs.

Frame configuration for the management of complex tibial fractures is highly variable and is dependent upon both fracture pattern and surgeon preference. The optimal number of rings to use when designing a frame remains uncertain. Traditionally larger, multi-ring-per-segment constructs have been assumed to offer optimal stability and therefore favourable conditions for fracture healing but there is little in-vivo evidence for this and the recent concept of reverse dynamisation challenges this approach.

Aortic arch anomalies represent a range of congenital vascular malformations resulting from disruptions in the typical embryological development of the aortic arch and its branches. These anomalies, which vary widely in their presentation, can lead to significant clinical symptoms depending on their structure and position. We report the case of a 75-year-old male with intermittent hypertension, palpitations, and episodic warmth in the upper body.
