The embedded mobile hydrogel methylmethacrylate ("HYDRON" Spofa) orbital implants introduced in the beginning of 70th years of 20th century was a new method to get good cosmetic effects after enucleation. At the Dept. of Ophthalmology of the Comenius University, Bratislava, the rejection rate of this type of orbital implants in the first years after enucleation (1971-1974) was only 16.8%. This technique was applied in patients after enucleation due to traumatic phtisis of the eye globe. Authors submit a case report of a female patient from the group of implanted mobile orbital implant HYDRON implanted in 1984. They analyze clinical features and histopathological findings after surgical removement 25 years after implantation.

Wearable systems for health monitoring are highly desired in personal diagnostics and precision medicine while challenges remain in constructing such wearable systems with reliability and high performance. Herein, we report a wearable platform for non-invasive monitoring biomarkers in sweat. The device is composed of a butterfly-shaped like microfluidic platform in which responsive photonic crystal hydrogels are embedded in each butterfly wing as sensors.

New stationary phases including polar embedded stationary phases that are capable of utilising green mobile phases have recently emerged. This study presents two straightforward strategies for preparing C18 phases with distinct polar-embedded groups: thioether (C18) and quaternary ammonium (C18). The two strategies were assessed based on convenience, cost, yield, and time efficiency.

Bacterial conjugation is the unidirectional transfer of DNA (often plasmids, but also other mobile genetic elements, or even entire genomes), from a donor cell to a recipient cell. In Gram-negative bacteria, it requires the formation of three complexes in the donor cell: i-a large, double-membrane-embedded transport machinery called the Type IV Secretion System (T4SS), ii-a long extracellular tube, the conjugative pilus, and iii-a DNA-processing machinery termed the relaxosome. While knowledge has expanded regarding molecular events in the donor cell, very little is known about the machinery involved in DNA transfer into the recipient cell.

As artificial intelligence advances and demand for cost-effective equipment maintenance in various fields increases, it is worth insightful research on utilizing robots embedded with sound source localization (SSL) technology for condition monitoring. Combining the two techniques has significant advantages, which are conducive to further classifying and tracking abnormal sources, thereby enhancing system performance at a lower cost. The paper provides an overview of current acoustic-based robotic techniques for condition monitoring, highlights the common SSL methods, and finds that localization performance heavily depends on signal quality.
