background: human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. therefore, the aim of this study was to remove formaldehyde from synthetic contaminated air by a re...

background: due to the presence of radioactive minerals such as monazite, the beach sand of the west coast of kanyakumari exhibits high natural background radiation. hair is a good indicator of radionuclides in the human body. an attempt is taken to measure the 210po activity in human hair samples and the factors affecting it. material and methods: 210po activity was analysed in 47 individuals ...

objective: objective: dermal papilla and hair epithelial stem cells regulate hair formation and growth cycle. damage to or losing of these cells can cause hair loss. although several studies have claimed to reconstitute hairs using rodent cells in animal model, a stable human hair follicle reconstitution protocol needs more studies. here in this study we evaluated hair induction through injecti...

Although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. Therefore, the aim of this study was to remove formaldehyde from synthetic contaminated a...

Objective(s): Chronic liver disease has become a major health problem that causes serious damage to human health. Since the existing treatment effect was not ideal, we need to seek new treatment methods. Materials and Methods: We utilized the gene recombination technology to obtain the human hair mesenchymal stem cells which overexpression of human hepatocyte growth factor (hHGF). Furthermore, ...

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...

manganese and cobalt concentrations in hair and nail were determined by flame atomic absorption spectrophotometer (aas).the mean manganese in hair and nail were 0.54 â± 0.35mg/g and 0.68 â± 0.30mg/g while the mean cobalt in hair and nail were 0.30 â± 0.24mg/g and 0.460.37mg/g respectively. a progressive increase in cobalt concentrations in hair and nails with age indicated no significant differ...

Background: One of the key questions in biochemistry is why cell becomes aged and what are the involved factors? Why cell growth is stopped after some divisions and cells become senescent? This occurs in a greater frame in the whole body and cells dye after a while. Androgenetic alopecia (AGA) is characterized by a loss or decrease in hair follicle size, which could be related to the loss of ha...

how the seeds of delphinium staphisagria promote hair growth in humans is yet to be discovered. this lack of information leads us to the investigation of hair promoting effects of seeds of delphinium staphisagria in vitro. extract prepared from the seed of delphinium staphisagria (esds) - traditionally used for hair loss treatment - was selected and tested for the cytotoxic and angiogenic poten...
