Researchers at USC have developed a groundbreaking brain imaging technique that reveals how tiny blood vessels in the brain pulse with each heartbeat, which may hold clues to aging and diseases like Alzheimer's. The method shows that microvascular pulsatility increases with age, especially in deep white matter, a region critical for co...
The research team has developed a velocity-constrained Kalman filtering algorithm that improves microbubble tracking accuracy, maps spatial distribution and movement direction of microvascular networks, and quantifies changes in blood flow speed. The technology also addresses challenges like motion compensation and low frame rates.
Researchers at CRCHUM have discovered a crucial biomarker, miR-423-5p microRNA, to predict kidney function and diagnose chronic renal failure. The breakthrough could lead to early diagnosis, targeted approaches, and improved treatment options for millions of patients worldwide.
Prolonged sitting impairs forearm cutaneous vascular function, but alternating local skin cooling and heating alleviates this effect. This study found that ambient temperature modulation can mitigate the decline in cutaneous vascular function.
Researchers used advanced imaging techniques to create detailed maps of mouse brains, identifying areas vulnerable to blood vessel degeneration. These changes can lead to cognitive decline and neurodegenerative disorders like Alzheimer's disease.
Researchers found that regorafenib synergizes with TAS102 to inhibit cancer growth, angiogenesis, and microvessel density in preclinical models of colorectal and gastric cancers. The combination also suppresses ERK1/2 activation regardless of KRAS or BRAF mutational status.
Researchers have developed a biodegradable fluorescent nanoprobe to detect diabetic retinopathy (DR) at its early molecular stage. The nanoprobe binds to VEGFR-2, expressed in the retinal microvessels, allowing for early diagnosis and intervention.
Researchers have identified hundreds of genes with significant stroke-driven changes and likely relevance in human strokes. The study found alterations in sphingolipid production, which are involved in regulating blood vessels, and pinpointed several molecular pathways that can be targeted for stroke treatment.
A clinical study found that severe COVID-19 patients exhibit impaired microvascular function, which correlates with disease severity. Non-invasive near-infrared spectroscopy monitoring may help predict disease course and select responders to novel therapies.
Scientists have detailed the normal human blood-nerve barrier transcriptome for the first time, revealing 12,881 RNA transcripts that define its structure and function. This comprehensive guide will help physicians understand how to keep nerves healthy and design targeted treatments for peripheral nerve disease.
Researchers have discovered a previously unknown protective mechanism in mice that helps remove blood clots and other blockages from the brain. The finding provides insights into mechanisms involved in age-related cognitive decline, Alzheimer's disease, and recovery from stroke.
Treating acute heart attacks with thrombus aspiration results in improved 1-year clinical outcomes, including lower cardiac death rates and fewer non-fatal heart attacks. This innovative approach to treatment appears to be more effective than traditional percutaneous coronary intervention (PCI) alone.
Scientists suggest elephants have an aquatic ancestry, supported by their unique pleural space and snorkeling behavior. The elephant's dense connective tissue replaces delicate pleura, allowing for some sliding of the two surfaces across each other.
A study found that the GSTP1 polymorphism was associated with increased survival in patients with advanced colorectal cancer who received platinum-based chemotherapy. Meanwhile, research on human herpesvirus-8 suggested that the K1 gene may play a role in malignant transformation.
