Jesses allow a falconer to keep control of a bird while it is on the glove or in training, and allow a bird to be secured on a perch outside its aviary. Jesses come in various types: Jesses are generally made from strips of leather as thin as possible, for which purpose kangaroo leather has become increasingly popular over the years, as it
Tether (cell biology) Tether (cell biology) Biological cells which form bonds with a substrate and are at the same time subject to a flow can form long thin membrane cylinders called tethers, which connect the adherent area to the main body of the cell. Under physiological conditions, neutrophil tethers can extend to several micrometers. In biochemistry, a tether is a molecule that carries 1 or 2 carbon intermediates from one active site to another. They are commonly used in lipid synthesis, gluconeogenesis, conversion of pyruvate into Acetyl CoA via PDH complex. Common tethers are lipoate -lysine residue complex associated with dihydrolipoyl transacetylase, which
