Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

Advanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

An investigation of an autonomic innervation of the vertebral artery using monoamine histofluorescence

European Journal of Histochemistry, 2009
Blood flow to the hindbrain, via the paired vertebral arteries, must be uncompromised for adequate neurological functioning of its vital centres. Therefore, it would seem unlikely that the intracranial vertebral artery would need to vasoconstrict, thus ...

HISTOMORPHOLOGICAL STUDY ON THE CAROTID SINUS IN RABBIT

The Iraqi Journal of Veterinary Medicine, 2022
Histomorphological study confirmed that the carotid sinus was characterized by an abrupt thinning of elastic tunica media which was rapidly replaced by the normal muscularity of the media on the distal progression in the internal carotid artery.

Plant Metabolites Screening Identifies 7‐epi‐10‐Deacetyltaxol Inhibiting Cell Division by Interfering With the Cell Cycle and Microtubule Organization

Advanced Science, EarlyView.
In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression. These findings

Salvianolic Acid a Disrupts the HSP90α‐AKT‐PERK Ternary Complex to Alleviate Atherosclerosis by Activating Endoplasmic Reticulum Stress of Senescent Vascular Smooth Muscle Cells

Advanced Science, EarlyView.
Salvianolic acid A (SAA) selectively induces senescent vascular smooth muscle cell apoptosis, alleviating atherosclerosis. Mechanistically, SAA targets heat shock protein 90 alpha (HSP90α) to disrupt the protein inase B (AKT)‐PRKR‐Like Endoplasmic Reticulum Kinase (PERK) scaffold, driving ubiquitin‐proteasome‐dependent AKT degradation.

Cryopreserved human aortic root allografts arterial wall: Structural changes occurring during thawing. [PDF]

PLoS ONE, 2017
BACKGROUND:The aim of our experimental work was to assess morphological changes of arterial wall that arise during different thawing protocols of a cryopreserved human aortic root allograft (CHARA) arterial wall.

Delayed traumatic superficial femoral artery pseudoaneurysm and arteriovenous fistula over the left lower limb

Indian Journal of Vascular and Endovascular Surgery, 2022
A pseudoaneurysm is a pulsating, encapsulated hematoma in communication with a ruptured vessel (1); there is an accumulation of blood between the tunica media and tunica adventitia layers of the vessel. We report a case of a young male with complaints of

Ilexoside K Ameliorates Atherosclerosis by Suppressing CD72hi Macrophages and Blocking CXCL12–CXCR4 Axis to Inhibit Endothelial Pyroptosis

Advanced Science, EarlyView.
CD72hi macrophages drive endothelial pyroptosis and accelerate atherosclerosis through CXCL12–CXCR4‐mediated immune–vascular crosstalk. Ilexoside K suppresses this pathogenic communication by modulating CXCR4‐dependent endothelial responses, reducing inflammation and plaque progression. These findings reveal a macrophage–endothelial regulatory axis and

DUET‐seq: An Open‐Source Droplet Platform for High‐Fidelity Joint Chromatin and Transcriptome Profiling Reveals Temporal Regulatory Decoupling in Single Cells

Advanced Science, EarlyView.
DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.
