Pathophysiology of Slow-Flow Vascular Malformations: Current Understanding and Unanswered Questions

Journal of Vascular Anomalies, 2023
Background:. Slow-flow vascular malformations include venous, lymphatic, and lymphaticovenous malformations. Recent studies have linked genetic variants hyperactivating either the PI3K/AKT/mTOR and/or RAS/RAF/MAPK signaling pathways with slow-flow ...

An Unusual Case of Giant Arterio-Venous Malformation of Anterior Abdominal Wall [PDF]

Journal of Clinical and Diagnostic Research, 2017
Arterio-Venous Malformations (AVMs) are high flow vascular anomalies, commonly seen in head, neck and extremities. AVMs represent a direct connection between the arterial and the venous systems.

Rapamycin and treatment of venous malformations

Current Opinion in Hematology, 2019
Purpose of review The field of vascular anomalies has seen a fundamental change during the past 10 years. The identification of somatic genetic mutations as the explanation of sporadic vascular anomalies opened the doors to study prospectively and a posteriori the causes of various vascular malformations. This was helped by the

Venous Malformation of the Maxilla: A Systematic Review and a Report of an Unusual Case

Surgeries
Background: Venous malformation, formerly designated as cavernous hemangioma, is a rare vascular lesion characterized by significant endothelial cells proliferation, predominantly affecting young females. Diagnosis is challenging due to its low incidence

Embryonic Stem Cell-Like Subpopulations in Venous Malformation

Frontiers in Medicine, 2017
Background Venous malformation (VM) consists of a network of ectatic anomalous thin-walled venous channels. A role for an activating TIE2 mutation in the development of the dilated luminal vessels in VM, and its proposed involvement of embryonic stem ...

Expanding Hereditary Spastic Paraplegias Limits: Biallelic SPAST Variants in Cerebral Palsy Mimics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegias (HSP) are rare neurodegenerative disorders marked by spasticity and lower limb weakness. The most common type, SPG4, is usually autosomal dominant and caused by SPAST gene variants, typically presenting as pure HSP.

Unrolling of Syngonium podophyllum: Functional Anatomy, Morphology and Modelling of Its Peltate Leaves

Advanced Biology, EarlyView.
The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.
