Structures and Functions of Chromatin Fibers
Annual Review of Biophysics, 2021In eukaryotes, genomic DNA is packaged into chromatin in the nucleus. The accessibility of DNA is dependent on the chromatin structure and dynamics, which essentially control DNA-related processes, including transcription, DNA replication, and repair.

Textile Research, 1942
Fundamental research in the chemical structure of fibers has received increasing attention in recent years. This research has gone hand in hand with the improvement of regenerated and synthetic fibers, that has brought rayon. to its present commanding position among textile fibers.

Mechanochromic Fibers with Structural Color
ChemPhysChem, 2015AbstractResponsive photonic crystals have been widely developed to realize tunable structural colors by manipulating the flow of light. Among them, mechanochromic photonic crystals attract increasing attention due to the easy operation, high safety and broad applications.

The importance of atrial structure and fibers
Clinical Anatomy, 2008AbstractAtrial structures are important in the current era of cardiac interventions using percutaneous transcatheter procedures. Understanding their locations and component parts helps to reduce risks of procedural‐related damage. The general arrangement of the myofibers that make up the atrial walls is reviewed to provide a morphologic basis for ...

Structure of the Giant Fibers of Earthworms
Science, 1970The median giant fiber and the pair of lateral giant fibers that run the length of the ventral nerve cord in earthworms were thought to arise by fusion of the axons of several nerve cells in each segment. The structure of these giant fibers has now been examined with a fluorescent dye injected into single fibers.

Fiber content and structure in foods
The American Journal of Clinical Nutrition, 1978Crude fiber analysis does not accurately reflect the amount of dietary fiber in food materials, nor does it give a constant fraction of dietary fiber when used to compare sources in the diet. More accurate methods of estimating dietary fiber are compared.

Structural and Functional Fibers
Annual Review of Materials Research, 2017Historically, fibers are known to be relatively passive materials and are used primarily in textiles. Today, however, fibers with a range of functionalities such as electrical and thermal conductivity, superparamagnetic properties, temperature regulation, energy harvesting, and biomedical capability provide many possibilities.

Journal of Polymer Science Part A-2: Polymer Physics, 1969
AbstractModel fibers of polyethylene and nylon 6 were strained in the direction of the fiber axis and the internal deformation of the samples was studied by large‐angle and small‐angle x‐ray diffraction. The compression of samples along the fiber axis was successfully carried out, and the results obtained by x‐ray methods yielded more interesting ...

The Structure and Chemistry of Keratin Fibers
1973Publisher Summary This chapter focuses on the chemistry and structure of keratin fibers and reviews the mode of biosynthesis of the extremely heterogeneous families of proteins in the hair follicle. With considerable development in the techniques of electron microscopy and protein chemistry, a more detailed picture of the fine structure of the fiber ...
