Acetylcholinesterase fibers and the development of senile plaques
Brain Research, 1987A new, highly sensitive histochemical technique for actylcholinesterase (AChE) was applied to a study of Alzheimer's disease brain tissue. Many immature senile plaques were seen to be developing along AChE-positive axons in the hippocampus and neocortex. Single fibers often displayed multiple lesions, showing stages of initial swelling, ballooning with

Development of a Novel Optical Fiber Coupler
Sixth International Conference on Intelligent Systems Design and Applications, 2006Using the theory that the coupling ratio of fiber coupler changes periodically with center distance of two optical fibers, in the fabrication process of fiber coupler, the fiber is fused but not stretched when light begin to split. The reduction of diameter of fiber is dependent of the theological characteristic of the fused fiberglass, and the light ...

Elastic fiber during development and aging
Microscopy Research and Technique, 1997Elastin molecules aggregate in the extracellular space where they are crosslinked by stable desmosine bridges. The resulting polymer is structurally organized as branched fibers and lamellae, which, in skin, are wider (a few microns) in the deep dermis and become progressively thinner (fraction of a micron) towards the papillary dermis. Several general

Recent Developments in Fiber Optic Devices
IEEE Transactions on Microwave Theory and Techniques, 1982The advent of the fundamental transverse mode laser diode and low loss optical fiber has extended the wavelength range for communication systems into the optical spectrum region. The indispensable elements for the optical communication systems are light source, transmission medium, and detector.

Cytoplasmic stress fibers in the developing heart
The Anatomical Record, 1989AbstractRhodamine‐conjugated phalloidin staining was used to study the distribution of filamentous actin in the developing heart of embryonic chicks and rats during the morphogenetic period of cardiac septation. In the chick, intense fluorescence indicative of abundant filamentous actin was observed along the myocardium and in the mesenchymal ...

Development of the Cotton Fiber
1984Publisher Summary This chapter discusses the various facets of cotton-fiber development and focuses on some currently critical areas of investigation. In addition to its commercial importance, cotton fiber has several attributes that make it an experimental system of choice for the investigation of physiological and biochemical changes accompanying ...

Development of a mammalian series‐fibered muscle
The Anatomical Record Part A: Discoveries in Molecular, Cellular, and Evolutionary Biology, 2004AbstractThis study examines the processes by which multiply innervated, serially fibered mammalian muscles are constructed during development. We previously reported that primary myotubes of such a muscle, the guinea pig sternomastoid muscle, span from tendon to tendon and are innervated at each of the muscle's four innervation zones.

Brassinosteroids in cotton: orchestrating fiber development
New PhytologistSummaryCotton cultivation spans over 30 million hectares across 85 countries and regions, with more than half participating in the global cotton textile trade. The elongated cotton fiber cell is an ideal model for studying cell elongation and understanding plant growth and development.

Development of braided fiber-based stents
2014The mechanical behavior of stents is one of the important factors involved in ensuring their function in maintaining an open blood vessel. This study aims to study the development of different kinds of fiber-based stents, using braiding technology. Moreover, the impact of braiding angle and mandrel's diameter in the mechanical behavior of the stent is ...
