Very intensive lipid-lowering therapy significantly regresses atheroma volume at the lesion level compared to statin therapy alone. This study found greater enlargement of the minimum lumen area and more frequent transition to stable plaque phenotypes with alirocumab treatment.
Researchers found that cancer cells with multiple mutations alter cell competition, allowing them to infiltrate and form highly invasive tumors. The study identified a key mechanism, MMP21, which promotes the production of diffusely invasive cancer cells.
A new biopsy procedure is developed with a multispectral confocal endomicroscope to aid in lung tissue imaging. The system allows for simultaneous imaging of multiple fluorescent dyes, enabling unique identification and spectral unmixing.
Scientists aim to improve vein health for patients undergoing heart bypass surgery and dialysis. They discovered that two genes play a crucial role in smooth muscle cell differentiation, enabling veins to mature and function like arteries.
A study published in the American Journal of Roentgenology found that combining deep-learning reconstruction with a subtraction technique yielded optimal diagnostic performance for detecting in-stent restenosis by coronary CT angiography. This approach reduced radiation exposure while maintaining high image quality.
A study published by the University of Alabama at Birmingham found that T cell-derived interleukin-22 plays a crucial role in antibacterial defense of colonic crypts. The researchers discovered that two types of immune cells, innate and adaptive, have distinct roles in defending against pathogenic bacteria.
The study found that lipid-rich plaques detected by NIRS imaging are associated with adverse outcomes and can be used as a prognostic index for vulnerable plaques. High-risk plaques were identified in patients with recent myocardial infarction, and their presence was linked to increased risk of future cardiac events.
A novel approach is being tested to deliver care to those with moderate depression and anxiety using artificial intelligence. Researchers at UIC are developing a voice-enabled, AI virtual agent named Lumen to deliver Problem Solving Therapy (PST) to patients with moderate, untreated depressive and/or anxiety symptoms.
The DynamX Bioadaptor combines acute performance with unique benefits of arterial 'uncaging', allowing for positive adaptive remodeling and reduced target vessel revascularization. This innovation in device design may mitigate the persistent annualized event rate beyond one year.
Researchers have developed nanomaterial-based white LEDs with a record luminous efficiency of 105 lumens per watt, promising a promising energy-efficient lighting source for homes and offices. The new LEDs use commercially available blue LEDs combined with flexible lenses filled with quantum dots to create white light.
Research suggests that haemodynamic forces play a critical role in shaping endothelial cells during angiogenesis, leading to the expansion and maintenance of vascular lumens. The study's findings challenge previous ideas about blood flow's impact on vascular development.
A team of scientists from Singapore and France has revealed the underlying mechanism for the formation and growth of epithelial tubes. They found that the shape and size of these tubes are governed by mechanical forces arising from cell interaction with the extracellular matrix, influencing lumen morphology and elongation direction.
Researchers from MDC have discovered a novel molecular signaling pathway in the kidney that regulates epithelial barrier function and lumen expansion. The Grhl2 transcription factor teams up with Ovol2 to control genes essential for forming an impermeable barrier.
Lumina Decision Systems' Analytica software helped stakeholders reach near consensus on a 'rigs to reefs' policy option, reducing costs and preserving marine ecosystems. The tool was successful in distilling rhetoric to meaningful discussion of tradeoffs and values.
The DESolve bioresorbable scaffold system demonstrates good efficacy and safety with low rates of late lumen loss and major coronary adverse events at six months. Early vessel restoration is indicated by significant increases in vessel, scaffold, and luminal areas.
A study by McConnell et al. reveals that intestinal microvilli extend their function beyond nutrient absorption, releasing vesicles packed with enzymes into the gut lumen for enhanced nutrient breakdown and defense against pathogens like lipopolysaccharide
Engineers have achieved a new record in efficiency of blue organic light-emitting diodes (OLEDs), which can produce high-quality white light similar to standard incandescent bulbs. The breakthrough paves the way for more efficient and affordable lighting solutions.
Two studies found that carotid angioplasty with stenting is as effective as endarterectomy in the medium term, but carries higher risk of stroke within 30 days. The average annual risk of ipsilateral stroke is 1% or less, regardless of treatment.
Scientists at the University of Michigan and Princeton University have discovered a way to enhance light output in organic light-emitting devices, emitting approximately 70 lumens from a single watt of power. This innovation pushes more appealing white light, reducing energy consumption and reliance on coal-generated electricity.
The National Institute of Standards and Technology (NIST) has developed the first two standards for solid-state lighting in the US, detailing color specifications and test methods for LED lamps and light fixtures. These standards aim to significantly reduce energy consumption and improve color rendering.
Researchers propose new model for predicting post-hospital death risk in aortic dissection patients based on blood clotting in the false lumen. Partial clotting is associated with a much greater risk of death, while those with patent or completely thrombosed false lumens have intermediate and lower risks respectively.
Researchers at UCLA have achieved a record-breaking 18 lumens per watt for red phosphorescent LEDs using a new combination of polymer-infused liquid, resulting in brighter, clearer pictures and slimmer profiles. The development aims to make future LED TVs cheaper while maintaining high image quality.
