Pulsed vacuum arc deposition of nitrogen-doped diamond-like coatings for long-term hydrophilicity of electrospun polycaprolactone scaffolds [PDF]
arXiv, 2022 The surface hydrophobicity of poly($\epsilon$-caprolactone) electrospun scaffolds prevents their interactions with cells and tissue integration. Plasma treatment of the scaffolds enhances their hydrophilicity. However, the hydrophobicity of scaffolds is restored in about 30 days.

Phytochemical study and evaluation of the cytotoxic properties of methanolic extract from Baccharis obtusifolia [PDF]
International Journal of Medicinal Chemistry, 2018, 2019 Some species of the Baccharis genus have been shown to possess important biomedical properties, including cytotoxic activity. In this study, we examined the cytotoxic effect of methanol extract from Baccharis obtusifolia (Asteraceae) in cancer cell lines of prostate (PC-3), colon (RKO), astrocytoma (D-384), and breast (MCF-7).

Bioactive SrO-SiO2 glass with well-ordered mesopores: Characterization, physiochemistry and biological properties [PDF]
, 2011 For a biomaterial to be considered suitable for bone repair it should ideally be both bioactive and have a capacity for controllable drug delivery; as such, mesoporous SiO2 glass has been proposed as a new class of bone regeneration material by virtue of

FEBS Letters, EarlyView.The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Shape-programmable Adaptive Multi-material Microrobots for Biomedical Applications [PDF]
arXiv, 2023 Flagellated microorganisms can swim at low Reynolds numbers and adapt to changes in their environment. Specifically, the flagella can switch their shapes or modes through gene expression. In the past decade, efforts have been made to fabricate and investigate rigid types of microrobots without any adaptation to the environments.

An effective network reduction approach to find the dynamical repertoire of discrete dynamic networks [PDF]
Chaos 23 (2), 025111 (2013), 2013 Discrete dynamic models are a powerful tool for the understanding and modeling of large biological networks. Although a lot of progress has been made in developing analysis tools for these models, there is still a need to find approaches that can directly relate the network structure to its dynamics.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
