Journal of Investigative Dermatology, 1976 During the last 25 years, cutaneous biologists have been particularly interested in abnormal cutaneous vascular patterns, the profusion of capillary anastomoses, the leakiness of venules, clotting, fibrinolysis, and blood viscosity. As a result, the effects of hypoxia and the factors that encourage new vessel proliferation are better understood than ...

Heterotransplantation of blood vessels [PDF]
Experimental Biology and Medicine, 1906 It is well known that the tissues of an animal do not grow or grow hardly at all in an animal of another species.

VesselVAE: Recursive Variational Autoencoders for 3D Blood Vessel Synthesis [PDF]
, 2023 We present a data-driven generative framework for synthesizing blood vessel 3D geometry. This is a challenging task due to the complexity of vascular systems, which are highly variating in shape, size, and structure. Existing model-based methods provide some degree of control and variation in the structures produced, but fail to capture the diversity ...

Blood Vessels Under the Microscope [PDF]
, 2020 This paper looks at blood vessels. All humans and animals have blood vessels, including your pet rabbit or dog, a whale or a giraffe! We need blood vessels to stay alive.

Identification of novel small molecule inhibitors of ETS transcription factors
FEBS Letters, EarlyView.ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six

Blood flow reprograms lymphatic vessels to blood vessels [PDF]
Journal of Clinical Investigation, 2012 Human vascular malformations cause disease as a result of changes in blood flow and vascular hemodynamic forces. Although the genetic mutations that underlie the formation of many human vascular malformations are known, the extent to which abnormal blood flow can subsequently influence the vascular genetic program and natural history is not.

Application of Top-hat Transformation for Enhanced Blood Vessel Extraction [PDF]
arXiv, 2022 In the medical domain, different computer-aided diagnosis systems have been proposed to extract blood vessels from retinal fundus images for the clinical treatment of vascular diseases. Accurate extraction of blood vessels from the fundus images using a computer-generated method can help the clinician to produce timely and accurate reports for the ...

Fractals and fractal dimension of systems of blood vessels: An analogy between artery trees, river networks, and urban hierarchies [PDF]
Fractal Geometry and Nonlinear Analysis in Medicine and Biology,
2015, 1(2): 26-32, 2015 An analogy between the fractal nature of networks of arteries and that of systems of rivers has been drawn in the previous works. However, the deep structure of the hierarchy of blood vessels has not yet been revealed. This paper is devoted to researching the fractals, allometric scaling, and hierarchy of blood vessels.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...
