Article Abstract
In recent years, the attachment mechanism of the octopus sucker has attracted the interest of scientists from different research areas, including biology, engineering, medicine and robotics. From a technological perspective, the main goal is to identify the underlying mechanisms involved in sucker attachment for use in the development of new generations of artificial devices and materials. Recently, the understanding of the morphology of the sucker has been significantly improved; however, the mechanisms that allow attachment remain largely unknown. In this work, we present new anatomical findings: specifically, a protuberance in the acetabular roof in five different octopus species; previously, this protuberance was identified by the authors in Octopus vulgaris. Moreover, we discuss the role of the protuberance and other anatomical structures in attachment with minimal energy consumption.

We previously used a disease-specific B cell receptor (BCR) point mutation (IGLV3-21R110) for selective targeting of a high-risk subset of chronic lymphocytic leukemia (CLL) with chimeric antigen receptor (CAR) T cells. Since CLL is a disease of the elderly and a significant fraction of patients is not able to physically tolerate CAR T cell treatment, we explored bispecific antibodies as an alternative for precision targeting of this tumor mutation. Heterodimeric IgG1-based antibodies consisting of a fragment crystallizable region (Fc) attached to both an anti-IGLV3-21R110 Fab and an anti-CD3 (UCHT1) single chain variable fragment (R110-bsAb) selectively killed cell lines engineered to express high levels of the neoepitope as well as primary CLL cells using healthy donor and CLL patient-derived T cells as effectors.

The mechanical properties of the polymeric substrate or matrix where a cell grows affect cell behavior. Most studies have focused on relating elastic properties of polymeric substrates, which are time-independent, to cell behaviors. However, polymeric substrates and biological systems exhibit a time-dependent, often viscoelastic, mechanical response.

This systematic review and meta-analysis aimed to evaluate the long-term clinical outcomes of regenerative procedures compared with access flap surgery for the treatment of intrabony defects, with a minimum follow-up period of 5 years. A systematic review protocol following PRISMA guidelines was conducted. Both electronic and manual searches were conducted to identify randomized clinical trials (RCTs) on regenerative treatment of deep intrabony defects (≥3 mm) with a follow-up of at least 5 years.

Hybrid systems (HSs) of quantum dots (QDs) and molecular photoswitches exhibit luminescence switching of QDs based on energy transfer and have garnered attention for their potential applications in sensors and optical memories. In HSs, the chemical composition, such as the number of attached ligands, is inherently distributed, posing challenges for extracting the energy transfer process from the QDs to a single acceptor molecule. The stochastic model, assuming a Poisson distribution for the number of acceptors, proves to be an effective approach for extracting the process.

The passive rotation of rigid helical filaments is the propulsion strategy used by flagellated bacteria and some artificial microswimmers to navigate at low Reynolds numbers. In a classical 1976 paper, Lighthill calculated the 'optimal' resistance coefficients in a local (logarithmically accurate) resistive-force theory that best approximates predictions from the non-local (algebraically accurate) slender-body theory for force-free swimming of a rotating helix without an attached load (e.g.
