Stent loss in coronary arteries is a rare complication of coronary intervention. Furthermore, the entanglement of a lost stent with a second previously deployed stent leading to a very complicated scenario has not been reported previously. In this case, we are presenting the first case report of a stent loss due to the entanglement of a stent with the ostial part of the second already deployed side branch stent leading to distortions of the second stent and entrapment. This is also the first case report describing the successful and simultaneous retrieval of both the lost and entangled deployed stents percutaneously using the distal inflating balloon technique.

Patterning soft materials with cell adhesion motifs can be used to emulate the structures found in natural tissues. While patterning in tissue is driven by cellular assembly, patterning soft materials in the laboratory most often involves light-mediated chemical reactions to spatially control the presentation of cell binding sites. Here we present hydrogels that are formed with two responsive crosslinkers-an anthracene-maleimide adduct and a disulfide linkage-thereby allowing simultaneous or sequential patterning using force and UV light.

The lack of molecular backscattering detection capability has limited the calibrated backscattering measurements until recent advances in coherent lidar technology. In this work, the simultaneous detection of aerosol and molecular backscattering is demonstrated with coherent heterodyne lidar, and the results are compared with a state-of-the-art Raman lidar PollyXT as a reference in a long-range for the first time.
View Article and Find Full Text PDFFiber link failure is a common and frequent failure type in terrestrial optical networks (TONs). To guarantee the stable operation of the TON against single or multi-link failures, various kinds of survivability technologies have been proposed. Although these survivability technologies are effective in many cases, a link cut set (LCS), which is a set of fiber links whose simultaneous failures can disconnect the TON, presents an extreme situation of network partitioning that these technologies cannot address.

The trophectoderm (TE) is the first tissue to differentiate during the preimplantation development of the mammalian embryo. It forms the outer layer of the blastocyst and is responsible for generating the blastocoel, a fluid-filled cavity whose expansion is essential for successful hatching and implantation. Here, we investigated the role of the small GTPase RHOA in the morphogenesis of the TE, particularly its relationship with HIPPO signaling, using mouse embryos as a model.

ConspectusIons are the crucial signaling components for living organisms. In cells, their transportation across pore-forming membrane proteins is vital for regulating physiological functions, such as generating ionic current signals in response to target molecule recognition. This ion transport is affected by confined interactions and local environments within the protein pore.
