Arterial stenosis, pressure, and flow
The Journal of Thoracic and Cardiovascular Surgery, 1976 The interaction between the effects of an arterial stenosis and postocclusion hyperemia was studied in a model of the capillaron system. A capillaron is a module consisting of soft-walled permeable vessels (capillaries) in a compliant capsule. Stenosis reduced flow in accord with arterial cross-sectional area. Addition of a capillaron reduced flow to a

Non‐Surgical, In‐Stent Membrane Bioelectronics for Long‐Term Intracranial Pressure Monitoring
Advanced Healthcare Materials, EarlyView.This image shows a sequence of long‐term intracranial pressure monitoring using non‐surgical, in‐stent membrane bioelectronics. Abstract Traditional intracranial pressure (ICP) monitoring methods, using intraventricular catheters, face significant limitations, including high invasiveness, discrete data, calibration complexities, and drift issues, which

Effect of hypertension on low-density lipoprotein transport within a multi-layered arterial wall: modelling consistent with experiments [PDF]
arXiv, 2016 The influence of hypertension on low-density lipoproteins intake into the arterial wall is an important factor for understanding mechanisms of atherosclerosis. It has been experimentally observed that the increased pressure leads to the higher level of the LDL inside the wall.

Advanced Healthcare Materials, EarlyView.Clinical translation of biohybrid medical implants requires the previous implementation of drying schemes that can facilitate their sterilization and storage. This study addresses that critical aspect and elucidates the impact of drying on biohybrid vascular grafts, highlighting the need for implant‐specific drying strategies to ensure safety ...

Arterial pressures in a general practice
Annals of Human Biology, 1974 Systolic and diastolic readings of blood pressure were recorded for 5386 (2585 males and 2801 females) members of a general practice situated in and around Ballycastle, County Antrim. Polynomials to predict blood pressure from age were derived for systolic and diastolic pressures of males and females. Polynomials to predict blood pressure variance from

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...
