Lignin‐Containing Nanocellulose Mediated Interlayer Modulation Unlocks Stable and Redispersible MXene

open access: yesAdvanced Science, EarlyView.
Amphiphilic lignin‐containing nanocellulose (LNC) establishes competitive interactions between MXene nanosheets, enabling precise modulation of interlayer spacing and interfacial chemistry. This strategy allows rapid fabrication of semi‐solid MXene via industrial‐scale spray drying, achieving long‐term reversible redispersibility and exceptional ...

Propagation of Fibrillar Structural Forms in Proteins Stopped by Naturally Occurring Short Polypeptide Chain Fragments

open access: yesPharmaceuticals, 2017
Amyloids characterized by unbounded growth of fibrillar structures cause many pathological processes. Such unbounded propagation is due to the presence of a propagating hydrophobicity field around the fibril’s main axis, preventing its closure (unlike in

Tumor‐Tissue Boundaries as Instructive Interfaces in Breast Cancer Cell Invasion

open access: yesAdvanced Science, EarlyView.
Tumor‐tissue boundaries reprogram metastatic breast cancer cells, enhancing invasiveness through an instructive, not permissive, mechanism. Using a 3D collagen I‐based tumor‐tissue interface model, single‐cell analysis, and simulations, this study shows that all cells can transmigrate without selective filtering, highlighting a targetable process in ...

Tailored Electro–Magnetic–Porous Multigradient Nanoarchitectonics for Absorption‐Dominated Electromagnetic Interference Shielding and Adaptive Multifunctionality

open access: yesAdvanced Science, EarlyView.
An electro–magnetic–porous multigradient nanofibrous electromagnetic interference (EMI) membrane is fabricated via shear‐induced in situ fibrillation and layer‐by‐layer assembly. Leveraging a multigradient‐induced “impedance matching–polarization–reabsorption” synergistic mechanism, the membrane achieves absorption‐dominated high‐efficiency EMI ...

Biophysical Characterization of α-Synuclein and Rotenone Interaction

open access: yesBiomolecules, 2013
Previous studies revealed that pesticides interact with α-synuclein and accelerate the rate of fibrillation. These results are consistent with the prevailing hypothesis that the direct interaction of α-synuclein with pesticides is one of many suspected ...

Osborn Waves: History and Significance [PDF]

open access: yes, 2004
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...

A Single‐Molecule Pleuripotent Scaffold for Combinational Therapy of Alzheimer's Disease via Intranasal Administration

open access: yesAdvanced Science, EarlyView.
Herein, guanidinium‐modified calix[5]arene (GC5AY) is developed featuring small size, positive charge, and desirable amphiphilicity, that can efficiently traverse the nasal mucosal barrier for brain drug delivery. Additionally, possessing inherent therapeutic functions, GC5AY can thus serve as a single‐molecule pleuripotent scaffold for multi‐target ...

Health‐related quality of life following total minimally invasive, hybrid minimally invasive or open oesophagectomy: a population‐based cohort study

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
All patients operated for oesophageal cancer in Sweden from 2013 to April 2018 were identified, and 246 patients were recruited to this population‐based nationwide Swedish study. The results show that longitudinal health‐related quality of life after minimally invasive oesophagectomy was similar to that of the open surgical approach.

Slowing of electrical activity in ventricular fibrillation is not associated with increased defibrillation energies in the isolated rabbit heart

open access: yesFrontiers in Physiology, 2011
Prolonged out-of-hospital ventricular fibrillation (VF) arrests are associated with reduced ECG dominant frequency (DF) and diminished defibrillation success. Partial reversal of ischaemia increases ECG DF and improves defibrillation outcome.
