Multifractal Characterization and Modeling of Blood Pressure Signals

Algorithms, 2022
In this paper, a multi-fractal analysis on a diastolic blood pressure signal is conducted. The signal is measured in a time span of circa one day through the multifractal detrended fluctuation analysis framework.

Role of Tau Protein in Both Physiological and Pathological Conditions [PDF]

, 2004
The morphology of a neuron is determined by its cytoskeletal scaffolding. Thus proteins that associate with the principal cytoskeletal components such as the microtubules have a strong influence on both the morphology and physiology of neurons.

Erratic and blood vessel-guided migration of astrocyte progenitors in the cerebral cortex

Nature Communications, 2022
During development, astrocytes are generated from radial glia, and migrate to the cortical plate, but the process of astrocyte migration during development is not fully understood.

Essential Amino Acid Intake Is Required for Sustaining Serum Insulin-like Growth Factor-I Levels but Is Not Necessarily Needed for Body Growth

Cells, 2022
Essential amino acids (EAAs) are those that cannot be synthesized enough to meet organismal demand; therefore, it is believed that they must be taken from the diet for optimal growth. The growth hormone (GH)/insulin-like growth factor-I (IGF-I) system is

Mapping the current flow in sacral nerve stimulation using computational modelling

Healthcare Technology Letters, 2018
Sacral nerve stimulation (SNS) is an established treatment for faecal incontinence involving the implantation of a quadripolar electrode into a sacral foramen, through which an electrical stimulus is applied.

Albumin uptake and processing by the proximal tubule: physiological, pathological, and therapeutic implications

, 2022
For nearly 50 years the proximal tubule (PT) has been known to reabsorb, process, and either catabolize or transcytose albumin from the glomerular filtrate. Innovative techniques and approaches have provided insights into these processes. Several genetic

Altered ciliary morphology reduces mechanosensation in a cystic kidney model as indicated by a mathematical model

Scientific Reports
This study investigates the biomechanical properties of primary cilia in healthy kidneys and an early-stage cystic kidney model (CKM), focusing on their role in flow-mediated mechanosensation. Morphological analysis showed that CKM cilia are longer, more
