Interaction of void spacing and material size effect on inter-void flow localisation [PDF]

open access: yesJournal of Applied Mechanics (2021), 2020
The ductile fracture process in porous metals due to growth and coalescence of micron scale voids is not only affected by the imposed stress state but also by the distribution of the voids and the material size effect. The objective of this work is to understand the interaction of the inter-void spacing (or ligaments) and the resultant gradient induced

Sonoelastography in the diagnosis of tendinopathies: An added value [PDF]

open access: yes, 2015
BACKGROUND: sonoelastography helps in the detection of abnormalities not yet evident on B-mode exam. METHODS: in this observational study, we report a collection of cases of symptomatic patients without alterations at ultrasound imaging but with ...

Erythropoietin‐Stimulated Macrophage‐Derived Extracellular Vesicles in Chitosan Hydrogel Rescue BMSCs Fate by Targeting EGFR to Alleviate Inflammatory Bone Loss in Periodontitis

open access: yesAdvanced Science, EarlyView.
A therapeutic strategy is proposed for periodontitis using extracellular vesicles derived from EPO‐stimulated macrophages (EPO‐EVs). This schema demonstrates how EPO‐EVs enhance the osteogenic activity of mBMSCs in an inflammatory environment by inhibiting EGFR.

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...

Suspended Tissue Open Microfluidic Patterning (STOMP)

open access: yesAdvanced Science, EarlyView.
Suspended Tissue Open Microfluidic Patterning (STOMP) is a method that enables precise spatial patterning within a single suspended tissue. By leveraging capillary pinning and open microfluidics, STOMP facilitates the creation of complex tissue interfaces such as diseased‐healthy boundaries and tissue‐tissue junctions. This method integrates mechanical

Ligament break-up simulation through pseudo-potential Lattice Boltzmann Method [PDF]

open access: yesarXiv, 2019
The Plateau-Rayleigh instability causes the fragmentation of a liquid ligament into smaller droplets. In this study a numerical study of this phenomenon based on a single relaxation time (SRT) pseudo-potential lattice Boltzmann method (LBM) is proposed. If systematically analysed, this test case allows to design appropriate parameters sets to deal with

Small Extracellular Vesicles Orchestrate Cisplatin‐Induced Ototoxicity: Potential Biomarker and Targets Discovery

open access: yesAdvanced Science, EarlyView.
Cisplatin causes reactive oxygen species accumulation, leading to apoptosis and inflammation in cochlear hair cells. Small extracellular vesicles primarily derived from the damaged hair cells likely contribute to cisplatin‐induced ototoxicity, carrying a variety of microRNAs and proteins.

Deformation and breakup of the liquid ligament with various disturbances on the interface in shear flow [PDF]

open access: yesarXiv
This study performed a numerical analysis of the deformation and breakup of a liquid ligament with various disturbances on the interface in shear flow. The shear flow generates a three-dimensional flow and vortices around the liquid ligament. These vortices promote the movement of the liquid inside the liquid ligament.

Histological evidence for a supraspinous ligament in sauropod dinosaurs [PDF]

open access: yes, 2015
Supraspinous ossified rods have been reported in the sacra of some derived sauropod dinosaurs. Although different hypotheses have been proposed to explain the origin ofthis structure, histological evidence has never been provided to support or reject any
