Discrete mechanical growth model for plant tissue. [PDF]

open access: yesPLoS ONE, 2019
We present a discrete mechanical model to study plant development. The method is built up of mass points, springs and hinges mimicking the plant cell wall's microstructure. To model plastic growth the resting lengths of springs are adjusted; when springs

Mechanical forces of beating heart suppress cancer growth [PDF]

open access: yesMechanobiology in Medicine
The cardiac vasculature is characterized by high pressure, high blood flow, and dense vascular branching, which may increase its exposure to circulating tumor cells (CTCs). However, both primary cardiac tumors and metastases are remarkably rare.

Mechanical load regulates bone growth via periosteal Osteocrin

open access: yesCell Reports, 2021
Summary: Mechanical stimuli including loading after birth promote bone growth. However, little is known about how mechanical force triggers biochemical signals to regulate bone growth. Here, we identified a periosteal-osteoblast-derived secretory peptide,

Mechanical and aging performance of natural fiber-reinforced mycelium composites for sustainable packaging [PDF]

open access: yesScientific Reports
The increasing demand for sustainable and biodegradable alternatives to petroleum-based packaging materials has stimulated growing interest in mycelium-based bio-composites. In the present work, natural fiber-reinforced mycelium composites were developed

SOCIO-ECONOMIC AND MIGRATION ANALYSIS OF TYPICAL RURAL AREAS IN BULGARIA [PDF]

open access: yesTrakia Journal of Sciences, 2023
Rural areas hold a large part of the territory of Bulgaria, and migration processes have even greater importance after the COVID-19 pandemic. The purpose of this research is to review the trends in the socio-economic aspects and whether they are ...

Mechanics of cell growth [PDF]

open access: yesMechanics Research Communications, 2012
Cell growth describes an essential feature of biological tissues. This growth process may be modeled by using a set of relatively simple governing equations based on the axioms of mass and momentum balance, and using a continuum framework that describes cells and tissues as mixtures of a solid matrix, a solvent and multiple solutes.

Mechanical coupling coordinates microtubule growth

open access: yeseLife, 2023
During mitosis, kinetochore-attached microtubules form bundles (k-fibers) in which many filaments grow and shorten in near-perfect unison to align and segregate each chromosome. However, individual microtubules grow at intrinsically variable rates, which

Multi-Scale Probabilistic Analysis for the Mechanical Properties of Plain Weave Carbon/Epoxy Composites Using the Homogenization Technique

open access: yesApplied Sciences, 2020
Probabilistic analyses of carbon fabric composites were conducted using the Monte Carlo simulation based on a homogenization technique to evaluate the mechanical properties of composites and their stochastic nature. First, the homogenization analysis was

Complications in patients with transfusion dependent thalassemia: A descriptive cross‐sectional study

open access: yesHealth Science Reports, 2023
Background and Aims One of the most common hemoglobinopathies globally related to blood transfusion and iron overload in the body is thalassemia syndrome. Increasing ferritin levels can cause severe damage to the patient's body organs. This study aims to
