Purpose Female pattern hair loss (FPHL) is a common hair disease. However, studies of the quantitative measurement of FPHL are still limited. The aim of this study was to investigate the characteristics of hair density and hair diameter in normal women and FPHL patients, and further correlate the quantitative measurement with the clinical presentation of FPHL. Patients and methods An evaluati...
Systemic lupus erythematosus (SLE) is an autoimmune inflammatory disease, and environmental factors are proposed to exacerbate existing symptoms. One such environmental factor is mercury. The aim of this study was to investigate the relationship between exposure to mercury (Hg) and disease activity and disease associated damage in Total Hg concentrations in hair and urine were measured in 52 SL...
Alopecia areata (AA) is a recurrent, non-scarring type of hair loss affecting the hair follicles and sometimes the nails. Current evidence indicates that hair follicle inflammation in alopecia areata is caused by a T-cell mediated autoimmune mechanism occurring in genetically predisposed individuals. Environmental factors like infections, diet, vaccination and stress may be responsible for trig...
Organ regenerative therapy aims to reproduce fully functional organs to replace organs that have been lost or damaged as a result of disease, injury, or aging. For the fully functional regeneration of ectodermal organs, a concept has been proposed in which a bioengineered organ is developed by reproducing the embryonic processes of organogenesis. Here, we show that a bioengineered hair follicle...
Alopecia areata is thought to be a T-cell mediated and cytokine mediated autoimmune disease that results in non-scarring hair loss. Poliosis has been described as a localized depigmentation of hair caused by a deficiency of melanin in hair follicles. A 57-year-old man with a history of alopecia areata developed white hair regrowth in areas of previous hair loss. We retrospectively reviewed the ...
Inner ear sensory epithelia contain mechanosensitive hair cells that transmit information to the brain through innervation with bipolar neurons. Mammalian hair cells do not regenerate and are limited in number. Here we investigate the potential to generate mechanosensitive hair cells from mouse embryonic stem cells in a three-dimensional (3D) culture system. The system faithfully recapitulates ...
background: one of the pollutant components that can be observed in many industrial wastewaters is formaldehyde. the biological treatment of the wastewater contaminated by formaldehyde is very difficult due to its antibacterial property. however the removal of formaldehyde using adsorption process is feasible but it may be expensive. the main purpose of this study is to examine the adsorption o...
