1372 Biological effects of electrical epilation on human hair follicles and perifollicular skin ex vivo

In vitro and in vivo study of dye diffusion into the human skin and hair follicles.

We present experimental results on the in vitro and in vivo study of dye diffusion into human skin and hair follicles. We have studied some commercially available dyes for potential using in the laser selective thermolysis. The degree and the depth of hair follicle dyeing inside the skin were determined. For hairs in different stages the sebaceous gland was stated as a reservoir for a dye admin...

Histological in vitro evaluation of the effect of 27-MHz radiofrequency on ex vivo hair follicles

Expression of CD1d in human scalp skin and hair follicles: hair cycle related alterations.

BACKGROUND CD1d belongs to a family of antigen presenting molecules that are structurally and distantly related to the classic major histocompatibility complex class I (MHC I) proteins. However, unlike MHC I molecules, which bind protein antigens, CD1d binds to lipid and glycolipid antigens. CD1d is expressed by cells of lymphoid and myeloid origin, and by cells outside of the lymphoid and myel...

Systemic influence on activity of hair follicles in skin homografts.

ACTIVITY of the hair follicle is cyclic, periods of hair-growth alternating with periods of quiescence during which the dead hair is retained as a 'club'. In the rat, hair-growth occurs in a series of waves which start ventrally and pass over the flanks to the back (Dry, 1926; Butcher, 1934; Johnson, 1958a). The object of our work was to find out how far such activity is dependent upon factors ...

the effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
