Microneedles at the Forefront of Next Generation Theranostics

Advanced Science, EarlyView.
The TOC figure illustrates the revolutionary role of microneedles in modern medicine, showcasing their dual diagnostic and therapeutic functions. On the left, microneedles access interstitial fluid for real‐time monitoring of biomarkers like glucose and hormones.

Entrainment of Lymphatic Contraction to Oscillatory Flow [PDF]

arXiv, 2018
Lymphedema, a disfiguring condition characterized by the asymmetrical swelling of the limbs, is suspected to be caused by dysfunctions in the lymphatic system. Lymphangions, the spontaneously contracting units of the lymphatic system, are sensitive to luminal wall shear stress. In this study, the response of the lymphangions to dynamically varying wall

U-Net with Graph Based Smoothing Regularizer for Small Vessel Segmentation on Fundus Image [PDF]

ICONIP2019, 2020
The detection of retinal blood vessels, especially the changes of small vessel condition is the most important indicator to identify the vascular network of the human body. Existing techniques focused mainly on shape of the large vessels, which is not appropriate for the disconnected small and isolated vessels.

Extravasation of Borrelia burgdorferi Across the Blood–Brain Barrier is an Extremely Rare Event

Advanced Science, EarlyView.
Lyme disease is caused by vascular dissemination of the bacteria Borrelia. In a 3D tissue‐engineered microvessel model, Borrelia extravasation across the blood–brain barrier is extremely rare, implying that neuroborreliosis is not caused via direct cytotoxicity.

Spatio-temporal Models of Lymphangiogenesis in Wound Healing [PDF]

arXiv, 2016
Several studies suggest that one possible cause of impaired wound healing is failed or insufficient lymphangiogenesis, that is the formation of new lymphatic capillaries. Although many mathematical models have been developed to describe the formation of blood capillaries (angiogenesis), very few have been proposed for the regeneration of the lymphatic ...

Connexins in lymphatic vessel physiology and disease

FEBS Letters, 2014
Connexins are transmembrane proteins that form gap junction‐ and hemi‐channels. Once inserted into the membrane, hemi‐channels (connexons) allow for diffusion of ions and small molecules (<1 kDa) between the extracellular space and the cytosol. Gap junction channels allow diffusion of similar molecules between the cytoplasms of adjacent cells.

Verteporfin‐Mediated In Situ Nanovaccine Based on Local Conventional‐Dose Hypofractionated Radiotherapy Enhances Antitumor and Immunomodulatory Effect

Advanced Science, EarlyView.
Here gelatinase‐responsive methoxypolyethyleneglycol–PVGLIG–polycaprolactone (mPEG–PVGLIG–PCL) nanoparticles’ loading verteporfin (N@VP) is developed, enhancing radiotherapy via X‐ray‐triggered singlet oxygen generation. Combined with 2 Gy (gray, a radiation dose unit) irradiation, N@VP achieves antitumor efficacy comparable to 8 Gy, and also promotes ...

A Mathematical Model for Lymphangiogenesis in Normal and Diabetic Wounds [PDF]

arXiv, 2015
Several studies suggest that one possible cause of impaired wound healing is failed or insufficient lymphangiogenesis, that is the formation of new lymphatic capillaries. Although many mathematical models have been developed to describe the formation of blood capillaries (angiogenesis) very few have been proposed for the regeneration of the lymphatic ...

Tumor Microenvironment Triggered In Situ Coagulation of Supramolecularly Engineered Platelets for Precise Tumor Embolization

Advanced Science, EarlyView.
Occlusion of tumor blood vessels represents a promising yet challenging approach in cancer treatment. Herein, supramolecularly engineered platelets conjugated with morphology‐transformable nanoparticles is developed for precise tumor embolization. The engineered platelets actively accumulate at tumor sites following induced blood vessel injury.

Microwave lymphedema assessment using deep learning with contour assisted backprojection [PDF]

We present a method for early detection of lymphatic fluid accumulation in lymphedema patients based on microwave imaging of the limb volume across an air gap. The proposed algorithm uses contour information of the imaged limb surface to approximate the wave propagation velocity locally to solve the eikonal equation for implementing the adjoint imaging
