An optimization principle for initiation and adaptation of biological transport networks

Communications in Mathematical Sciences, 2019
. Structural optimization of biological transport networks, such as leaf venation and blood vessel systems, can be regarded as a consequence of natural selection.

Anion Transporters and Biological Systems

Accounts of Chemical Research, 2013
In this Account, we discuss the development of new lipid bilayer anion transporters based on the structure of anionophoric natural products (the prodigiosins) and purely synthetic supramolecular systems. We have studied the interaction of these compounds with human cancer cell lines, and, in general, the most active anion transporter compounds possess ...

Transport Through Biological Membranes [PDF]

open access: possibleAnnual Review of Physiology, 1957
Symposia on subjects related to transport through membranes provide a wealth of review articles and new facts (1 to 5). Frequent reference will be made to specific articles in these publications. Books dealing with special or general topics in the field include: Davson (6), LeFevre (7) , Harris (8), and Johnson, Eyring & Polissar (9). In: the following

Transport Pathways in Biological Membranes

Annual Review of Physiology, 1974
This review deals with transport through biological membranes. The term "mem­ brane" is used in a purely pragmatic sense: a sheet of unstirred material separating two solutions that can be considered well stirred. What unifies the concept of membrane is its physical function as a barrier as well as the methods by which such structures can be studied ...

On the adaption of biological transport networks affected by complex domains

The Physics of Fluids
This paper aims to simulate and analyze scenarios involving obstacles and parasitic organisms during the growth of biological structures. We introduce an innovative model of biological transport networks in complex domains.

Transport Through Biological Membranes

Annual Review of Physiology, 1955
This review covers, essentially, material published in the years 1960 and 1961. For reasons of space, work on plant cells, physicochemical studies on inanimate membranes, and most of the work on electrophysiology (even if it touched transport problems) had to be excluded.

Biological transportation networks: Modeling and simulation

Analysis and Applications, 2016
We present a model for biological network formation originally introduced by Cai and Hu [Adaptation and optimization of biological transport networks, Phys. Rev. Lett. 111 (2013) 138701]. The modeling of fluid transportation (e.g., leaf venation and angiogenesis) and ion transportation networks (e.g., neural networks) is explained in detail and basic ...

Transportation of Biological Materials

1987
As the use of genetically altered microorganisms increases, so will the need to transport these materials. Although the shipment of bioengineered materials raises fewer direct environmental concerns than intentional release or scale-up manufacturing, some important regulatory questions are presented.

Transport Through Biological Membranes

Annual Review of Physiology, 1959
The following topics are omitted from this review: transport across plant membranes, capillary permeability, and participation of ion transfer in cardiac activity. Two symposia of general interest were published: Metabolic A spects of Transport A cross Cell Membranes (200) and Hormonal Control of Water and Salt-Electrolyte Metabolism in Vertebrates (33)
