An adherence factor comprises a cell wall associated adhesin derived from Lactobacillus or a derivative, fragment, precursor or mutant of the adhesin, the adherence factor mediating adherence to epithelial cells and modulating gene expression to improve gut barrier function and gastrointestinal tract homeostasis. The support and a three point bearing achieves optimal conditions conferring minimal frictional losses between support element and inner wall of the handle cover and resilient stability to the umbrella. A hashing function, a compression function or a one-way cryptographic block function is used to encrypt the assembly-time constants.
