A method for identifying of the Y-Body in cells from hair root sheaths by fluorescent staining is described. In 52 normal males the Y-Body is found between 15 and 64%. 2 bodies were observed in 60 out of 5200 cells. In the female controls only rarely a fluorescent body was seen.

Root hairs: the villi of plants
Biochemical Society Transactions, 2021Strikingly, evolution shaped similar tubular structures at the µm to mm scale in roots of sessile plants and in small intestines of mobile mammals to ensure an efficient transfer of essential nutrients from ‘dead matter' into biota. These structures, named root hairs (RHs) in plants and villi in mammals, numerously stretch into the environment, and ...

The filamentous roots of mustard ( Raphanus sativus ), radish ( Brassica nigra ), squash ( Cucurbita pepo ), and wheat ( Triticum aestivum ) are covered throughout their length with living nucleated root hairs which may measure 1600 μ or more ...

Image analysis of hair — Hair roots extraction
2017 56th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2017There are many people suffering from loss of hair or thinning hair. There are, however, no methods to quantitatively know their hair condition such as hair density and hair thickness without cutting the hairs. Our final target is to develop a system which enables general people to easily and quantitatively know their hair condition without cutting the ...

A simple method is described by which sex chromatin can be studied in the cells of the external root sheath of single hairs. From a human capital hair many thousands of scorable nuclei can be obtained. Since this material is suitable for orcein staining, preparations are ready for analysis within a few minutes.

Root hairs are single cells specialized in the absorption of water and nutrients. Growing root hairs requires intensive cell wall changes to accommodate cell expansion at the apical end by a process known as tip growth. The cell wall of plants is a very rigid structure comprised largely of polysaccharides and hydroxyproline-rich O-glycoproteins.

Botanical Gazette, 1936
In the members of the monocotyledons investigated there exists a so-called "persistent" hirsuteness of practically the whole root system. The constituent cutinized hairs have been found to be of secondary cortical origin, superseding the primary epidermal ones. It seems logical that this condition may be associated with the lack of secondary thickening,

Enzyme Typing of Human Hair Roots
Journal of Forensic Sciences, 1978Abstract At present there exists no reliable means of characterizing human hair. Although several attempts have been made to provide improved techniques for the examination of hair, relatively little progress has been made [1]. In the present study, the possibility of detecting isoenzymes in hair roots after electrophoresis was ...

In this review, the value of root hairs as a model system for a broad range of electrophysiological experiments is highlighted by an introductory case study of their use for in situ measurements of vacuolar electrophysiology. Then, the basic tenets of electrophysiological measurements are presented: the electrical properties of the cell and how they ...

Root Hair Colonization by Mycorrhizal Fungi
2008Mycorrhizal fungi, i.e., the soil fungi that form mutualistic associations with many land plants, are provided by the host with carbon sources required to complete their life cycle, whereas they assist the plant in nutrient uptake from soil. Such acquisition is also considered to be one of the primary functions of root hairs. The aim of this chapter is
