Purpose: The retinal pigment epithelium (RPE) plays an important role in the pathogenesis of age-related macular degeneration (AMD) and other retinal degenerative diseases. The introduction of healthy RPE cell cultures into the subretinal space offers a potential treatment strategy. The aim of this study was the long-term culture and characterisation of RPE cells on nanofiber scaffolds.

Existing technologies, such as motion capture, can be expensive or require significant time to setup, collect data, and process and analyze the data. Other methods may rely on surveys or analog tools, which are subject to interpretation.

In this context, SrCu_{2}(BO_{3})_{2} is a faithful realization of the Shastry-Sutherland model for ideally frustrated spin dimers, even displaying several of its quantum magnetic phases as a function of pressure. We perform inelastic neutron scattering measurements on SrCu_{2}(BO_{3})_{2} at 5.

- Adenomyosis (AM) is a reproductive health condition where endometrial tissue grows into the uterine muscle, but its causes and development are not fully understood.
- A new type of cell, called pale cells, has been discovered; these cells lack certain connections and are seen moving through tiny breaks in the tissue, suggesting they may have unique properties.
- The research analyzed 40 hysterectomy samples to check for specific stem cell markers, finding that pale cells often expressed a stem cell marker called SSEA-1, hinting that these cells could play a role in the development of adenomyosis, and more research is needed to explore this further.
Article Synopsis
- The study aimed to evaluate whether ceramic materials could reduce glenoid erosion compared to metal in humeral hemiarthroplasties for patients with intact glenoid cartilage.
- Eight ceramic and nine metal prostheses were tested on cadaver shoulders using a simulator to mimic real-life joint activity and measure wear on the glenoid cartilage over time.
- Both materials showed significant cartilage wear, but there was no substantial difference between ceramic and metal in preserving cartilage integrity, suggesting that ceramic is not necessarily a better option for this application.
