Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Delivery actuator for a transcervical sterilization device [PDF]

, 2010
The use of delivery systems in the human body for positioning and deploying implants, such as closure devices, dilation balloons, stents, coils and sterilization devices, are gaining more importance to preclude surgical incisions and general anesthesia ...

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

Advanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Pericyte‐Assisted Vascular Lumen Organization in a Novel Dynamic Human Blood‐Brain Barrier‐on‐Chip Model

Advanced Healthcare Materials, EarlyView.
Organ‐on‐Chip (OoC) technology enables the precise modeling of the blood‐brain barrier (BBB). This study presents a microfluidic device that mimics brain microvessels, integrating co‐culture with pericytes and astrocytes under pulsatile flow. Results show that perivascular cells modulate endothelial morphology, promoting lumen formation and barrier ...

Tunable mechanical properties of the graphene/MoS2 tubal van der Waals heterostructure [PDF]

arXiv, 2018
We propose a tubal van der Waals heterostructure by rolling up the graphene and MoS2 atomic layers into a tubal form. We illustrate that the interlayer space for the tubal van der Waals heterostructure can be varied in a specific range, which is determined by the competition between the interlayer van der Waals force and the mechanical properties of ...

Low-Tubal-Rank Tensor Recovery via Factorized Gradient Descent [PDF]

IEEE Transactions on Signal Processing, Year:2024, Volume: 72, Pages: 5470 - 5483
This paper considers the problem of recovering a tensor with an underlying low-tubal-rank structure from a small number of corrupted linear measurements. Traditional approaches tackling such a problem require the computation of tensor Singular Value Decomposition (t-SVD), that is a computationally intensive process, rendering them impractical for ...

Tubal Matrices [PDF]

arXiv, 2021
It was shown recently that the f-diagonal tensor in the T-SVD factorization must satisfy some special properties. Such f-diagonal tensors are called s-diagonal tensors. In this paper, we show that such a discussion can be extended to any real invertible linear transformation.

Ovarian Function Restoration with Biomimetic Scaffold Incorporating Angiogenic Molecules and Antioxidant in Chemotherapy‐Induced Perimenopausal Model

Advanced Healthcare Materials, EarlyView.
This study developed a biomimetic scaffold incorporating PDRN and melatonin to restore ovarian function in chemotherapy‐induced premature ovarian insufficiency, enhancing cell survival, folliculogenesis, and hormone normalization, while improving fertility rates and offspring in a mouse model, offering a promising strategy for ovarian function ...

Essure: a revolution in female definitive contraception [PDF]

Einstein (São Paulo), 2009
Tubal sterilization is the most widely used procedure in the world for definitive contraception. It is safely performed by laparoscopy, but it is an invasive procedure with potential surgical and anesthetic risks. By hysteroscopy, the Essure micro-insert
