Summary: Studies have shown that collagen alignment in the breast tumor microenvironment significantly impacts cell-scale stiffness and force transmission between cells, with aligning fiber structures leading to up to a 35-fold difference in cell-scale stiffness. Precise control over fiber architecture can alter how contractile forces are transmitted through the fiber network, influencing cell communication within tissue microenvironments.

Summary: The present study developed a L-proline conjugated chitosan scaffold for wound healing. The scaffold was characterized by various tests and showed no cytotoxicity. In vitro experiments demonstrated that the modified scaffold promoted wound closure and collagen deposition. These findings suggest that the L-proline conjugated scaffold has potential as a wound dressing to improve wound healing.

Summary: This overview summarizes the evidence from systematic reviews on the use of warm needle acupuncture therapy for osteoarthritis (OA), and assesses the methodological quality of these reviews. The results show that warm needle acupuncture therapy is more effective than control conditions for OA, but the methodological quality of the reviews is low, indicating the need for improvements in evidence collection.

Summary: Wound healing-associated difficulties drive the need for innovative biotechnological approaches. Biomimetic approaches seem to be the most promising starting point. This study evaluates a crosslinked, porous collagen scaffold obtained through lyophilization and dehydrothermal reticulation and investigates its performance in terms of biocompatibility, cellular activity, inflammatory response, apoptosis, and biodegradation.

Summary: Collagen films cross-linked with glutaraldehyde at different pH values demonstrated varying physicochemical properties, with optimal cross-linking degree achieved under neutral and alkaline conditions. pH influenced the reaction position and degree, resulting in improved mechanical properties and thermal stability in the cross-linked films compared to non-cross-linked films. Control of reaction pH can be utilized to modulate the collagen films' properties for specific applications.

Summary: In this paper, an all metasurface integrated fiber solution is proposed for optical fiber-based spectroscopy sensors. By integrating metalenses, the focal spots of the excitation and collection beams are made to coincide, overcoming several challenges in fiber sensors. Furthermore, this solution can be applied to any optical fiber-based spectroscopy sensors.

Summary: This study explores dietary fiber supplements as potential modulators to reduce gut dysbiosis caused by antibiotics. The results suggest that fiber prebiotics significantly reduce the impact of antibiotic treatment on the microbiome composition and function, leading to a decrease in the abundance of anaerobic bacteria and metabolic pathways associated with oxidative metabolism.

Summary: This study investigated the genotoxic profile of varying degrees of esterification of unsaturated pyrrolizidine alkaloids (PAs). The results revealed that diester-type PAs had more pronounced effects than monoester-type PAs, including cytotoxicity, DNA damage, and cell cycle perturbation. Additionally, in vitro experiments showed that lasiocarpine had aneugenic effects.

Summary: The study introduces a nonlinear fibre-reinforced biomechanical model to investigate stress and contractile responses in airways within precision-cut lung-slices. Through numerical simulations and simplifying limits, the researchers successfully captured key elements of the full model behavior. The developed reduced model provides a more tractable approach for studying time-dependent feedback mechanisms linking airway mechanics and cytokine activation in asthma.

Summary: This study demonstrates the importance of balanced distribution of endothelial cells and regular vessel caliber in vascular network morphogenesis. It reveals that cell migration from veins towards arteries and cell proliferation in veins are the key factors in achieving this balance. The study also identifies the molecular regulator WASp and shows its role in coordinating cell migration through junctional actin assembly and PECAM1 recruitment. The findings have implications for understanding vascular malformations in humans.
