Pepsin Digestion for Proteomic Studies of the Human Hair Shaft. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Human hair shafts have received increased research interest owing to their easy accessibility and potential as a window for human health. Because the most abundant component in hair is protein, proteomics is a promising tool for studying the molecular composition of hair shafts.

A New Technique for Placing Pedicle Screws Into Bone Cement-Strengthened Vertebrae Involving Drilling and Melting. [PDF]
Orthop SurgExperimental results demonstrate that both solid bone cement blocks and bone cement in a dispersed state within bone tissue can be screwed in after thermal softening of the bone cement through Kirschner wires, achieving a good pull‐out resistance. ABSTRACT Objective Vertebroplasty with non‐degradable polymethyl methacrylate bone cement is a common ...

Rare Coexistence of Monilethrix and Trichorrhexis Nodosa in a Pediatric Patient: A Case Report [PDF]
Clin Case RepABSTRACT Monilethrix is a rare genetic disorder characterized by sparse, brittle hair, primarily affecting the scalp, although it may also affect other parts of the body. Trichorrhexis nodosa (TN) is another hair shaft disorder characterized by brittle and fragile hair shafts. Concurrence of monilethrix and TN is exceedingly rare.
