Scientists at the University of Osaka have created a new technique to build blood supply systems for artificial tissues. They successfully fabricated tubular hydrogel structures with controlled lumen sizes and complex geometries, paving the way for creating vascular models that can investigate the development of fully synthetic tissues.
The Global Centre for Asian Women’s Health found that a Mediterranean diet rich in fruits, nuts, whole grains, and healthy fats can reduce the risk of gestational hypertension and preterm birth. The study also linked narrowing of retinal arterioles before conception to reduced fetal growth during pregnancy.
A study at the Technical University of Munich found that people with long Covid experience altered blood vessels in the eye, which could be used to diagnose the condition. Persistent inflammatory responses were also linked to symptom severity and chronic inflammation.
Researchers highlight microvascular contributions to white matter injury in Alzheimer's disease, sparking calls for exploration of connections between AD, WM injury and cerebral small vessel disease. The study emphasizes the critical need to define mechanisms and diagnostic features of mixed vascular and AD neuropathological change.
Researchers found that microscopic blood vessel disease in the brain's white matter is associated with worse cognitive function and memory deficits in individuals with Alzheimer's. Lifestyle changes such as reducing hypertension, obesity, diabetes, and inactivity may help prevent or slow disease progression.
Researchers used OCT to study brain vascular imaging during real-time experimental stroke, revealing high-resolution images of in vivo vascular networks and biologically initiated rescue mechanisms. This could provide guidance for clinicians treating stroke patients.
Astrocytes play a crucial role in maintaining healthy vascular tone by releasing signals to dilate or constrict blood vessels as needed. This basal control helps regulate blood flow and prevent damage from excessive pressure or calcium levels.
A team of researchers created a 3D map of blood vessels in the cerebral cortex, revealing unexpected connections that don't align with neural cell organization. The study's findings have implications for functional brain imaging and our understanding of dementia.
A team of physicists and neuroscientists has discovered a bottleneck in the brain's blood supply, specifically in penetrating arterioles, which makes it vulnerable to strokes. This finding may explain the origin of gray matter damage detected in brain scans, especially among the elderly.
A study of over 3600 adults found that narrower arterioles and wider venules were associated with increased risk of coronary heart disease. The results suggest that retinal photography may be a useful non-invasive method for assessing this risk, particularly in women.
Belgian researchers have discovered a revolutionary approach to angiogenesis by opening up tumor blood vessels, allowing for improved access to cancer drugs and radiotherapy. The key to this ability lies in the peptide endothelin-1, which stimulates tumor cell proliferation and causes arterioles to contract.
A large study has found that retinal blood-vessel damage is associated with an increased risk of stroke. Damage to the small blood vessels in the retina was linked to a doubling of stroke risk, regardless of age, sex, or other health factors.
