Where Do You Get Your Protein? Or: Biochemical Realization [PDF]

open access: yes, 2020
Biochemical kinds such as proteins pose interesting problems for philosophers of science, as they can be studied from the points of view of both biology and chemistry.

A BIOCHEMICAL STUDY OF THE PHENOMENA KNOWN AS COMPLEMENT-SPLITTING [PDF]

open access: yesJournal of Experimental Medicine, 1912
It is generally accepted that complement may be split into a mid-piece and an end-piece. The mid-piece is thought to be in the globulin fraction, and the end-piece in the albumin fraction. The restoration of complement activity by putting together the albumin and globulin fractions does not prove, however, that each fraction contained a part of the ...

Molecular Electrostatic Potentials: An Effective Tool for the Elucidation of Biochemical Phenomena [PDF]

open access: yesEnvironmental Health Perspectives, 1985
The electrostatic potential V(r) that is created in the space around a molecule by its nuclei and electrons (treated as static distributions of charge) is a very useful property for analyzing and predicting molecular reactive behavior. It is rigorously defined and can be determined experimentally as well as computationally.

Microfluidic Device for the Analysis of Angiogenic Sprouting under Bidirectional Biochemical Gradients

open access: yesMicromachines, 2020
In this paper, we developed a spheroid culture device that can trap a spheroid in the trapping site sandwiched by two extracellular matrix gels located at the upper and lower side of the spheroid.

Bridging the gap between the micro- and the macro-world of tumors [PDF]

open access: yes, 2012
At present it is still quite difficult to match the vast knowledge on the behavior of individual tumor cells with macroscopic measurements on clinical tumors.

Probabilistic Inference with Polymerizing Biochemical Circuits

open access: yesEntropy, 2022
Probabilistic inference—the process of estimating the values of unobserved variables in probabilistic models—has been used to describe various cognitive phenomena related to learning and memory. While the study of biological realizations of inference has

Stochastic neural network models for gene regulatory networks [PDF]

open access: yes, 2003
Recent advances in gene-expression profiling technologies provide large amounts of gene expression data. This raises the possibility for a functional understanding of genome dynamics by means of mathematical modelling.

Non-mammalian model organisms in epigenetic research : an overview [PDF]

open access: yes, 2020
Recent advances in sequencing technology and genome editing tools had an indisputably enormous impact on our understanding of complex biological pathways and their genetic and epigenetic regulation.

Onsager's Wien Effect on a Lattice [PDF]

open access: yes, 2013
The Second Wien Effect describes the non-linear, non-equilibrium response of a weak electrolyte in moderate to high electric fields. Onsager's 1934 electrodiffusion theory along with various extensions has been invoked for systems and phenomena as ...

Observation of coherent delocalized phonon-like modes in DNA under physiological conditions [PDF]

open access: yes, 2016
Underdamped terahertz-frequency delocalized phonon-like modes have long been suggested to play a role in the biological function of DNA. Such phonon modes involve the collective motion of many atoms and are prerequisite to understanding the molecular ...
