Strength and Deformation Behavior of Fine-Grained Soils Reinforced with Hair Fibers and Its Application in Pavement Design

open access: yesJournal of Natural Fibers, 2022
Although waste hair fibers are consumed in agricultural and pharmaceutical industries, etc., their use in civil engineering is very limited. Because of fibrous nature, it can be used as reinforcement material in soil for sustainable development, similar ...

Facile and Efficient Enzymatic Methods for Harvesting or Removal of Cuticle Cells from Human Hair Shafts

open access: yesJournal of Natural Fibers, 2022
Human hair fibers are structurally organized as a cortex protected by an outer scaly sheath (cuticle). Developing methods to isolate these two compartments will help to elucidate their roles in hair biology and develop potential applications.

Efferent control of the electrical and mechanical properties of hair cells in the bullfrog's sacculus. [PDF]

open access: yesPLoS ONE, 2010
Hair cells in the auditory, vestibular, and lateral-line systems respond to mechanical stimulation and transmit information to afferent nerve fibers. The sensitivity of mechanoelectrical transduction is modulated by the efferent pathway, whose activity ...

Endoscopic removal of a massive trichobezoar in a pediatric patient by using a variceal ligator cap: A case report and literature review

open access: yesFrontiers in Medicine, 2022
A trichobezoar is commonly formed in the gastrointestinal tract by ingestion of an individual’s own hair. A trichobezoar formed by hair and artificial materials constitutes a rare etiology scarcely reported in the current literature.
