A unique case of commensalism: The beaver beetle Platypsyllus castoris (Leiodidae, Coleoptera) and its morphological adaptations

open access: yesJournal of Morphology, Volume 284, Issue 1, January 2023., 2023
We document in detail the morphology of adults of the beaver beetle Platypsyllus castoris with modern techniques, and interpret evolutionary changes linked with the specific life style of the beetle in the fur of the beaver. Platypsyllus displays numerous structural specializations which ensure mechanical stabilization, firm anchorage on the host, and ...

Advanced Microfluidic‐Based Wearable Electrochemical Sensors for Continuous Biochemical Monitoring

open access: yesAdvanced Electronic Materials, EarlyView.
Microfluidic‐based wearable electrochemical sensors are transforming non‐invasive health monitoring through real‐time biochemical analysis of sweat, saliva, and interstitial fluid. This review explores advances in microfluidic design, fabrication, and sensor integration while addressing biofluid variability, material compatibility, and scalability.

Biomedical applications of silk and its role for intervertebral disc repair

open access: yesJOR SPINE, Volume 5, Issue 4, December 2022., 2022
For years, researchers have been seeking a suitable biomaterial to repair and/or regenerate the intervertebral disc (IVD) and a promising candidate to fill this gap could be the application of silk. Therefore, this review aims to elaborate on the different origins from which silk is harvested, the characteristics of each silk type and how it can be ...

Human Cornea Proteome: Identification and Quantitation of the Proteins of the Three Main Layers Including Epithelium, Stroma, and Endothelium

open access: yesJournal of Proteome Research, 2012
Diseases of the cornea are common and refer to conditions like infections, injuries and genetic defects. Morphologically, many corneal diseases affect only certain layers of the cornea and separate analysis of the individual layers is therefore of ...

Controversies in spine research: Organ culture versus in vivo models for studies of the intervertebral disc

open access: yesJOR SPINE, Volume 5, Issue 4, December 2022., 2022
Abstract Intervertebral disc degeneration is a common cause of low back pain, the leading cause of disability worldwide. Appropriate preclinical models for intervertebral disc research are essential to achieving a better understanding of underlying pathophysiology and for the development, evaluation, and translation of more effective treatments.

Homotopical Dynamics IV: Hopf invariants and hamiltonian flows [PDF]

open access: yesarXiv, 2001
In a non-compact context the first natural step in the search for periodic orbits of a hamiltonian flow is to detect bounded ones. In this paper we show that, in a non-compact setting, certain algebraic topological constraints imposed to a gradient flow of the hamiltonian function $f$ imply the existence of bounded orbits for the hamiltonian flow of $f$

Multifunctional Biomimetic Nanotherapeutics for Anti‐Oxidative and Anti‐Inflammatory Synergistic Therapy of Corneal Neovascularization

open access: yesAggregate, EarlyView.
An anti‐inflammatory and antioxidant metal‐organic framework (MOF) nanoplatform was prepared via one‐pot self‐assembly. In vitro and in vivo studies demonstrated that the prepared MVPC nanoparticles can effectively scavenge overproduced reactive oxygen species at diseased sites, enhance IL‐10 secretion, and suppress VEGFA expression, offering a novel ...
