The covalent attachment of ubiquitin is an important determinant for selective protein degradation by the 26S proteasome in plants and animals. The specificity of ubiquitination is often controlled by ubiquitin-protein ligases (or E3s), which facilitate the transfer of ubiquitin to appropriate targets. One ligase type, the SCF E3s are composed of four proteins, cullin1/Cdc53, Rbx1/Roc1/Hrt1, Sk...

Predicate encryption is an important cryptographic primitive (see [3, 6, 11, 14]) that enables fine-grained control on the decryption keys. Roughly speaking, in a predicate encryption scheme the owner of the master secret key Msk can derive secret key SkP , for any predicate P from a specified class of predicates P. In encrypting a message M , the sender can specify an attribute vector ~x and t...

The galvanic couple AA2024/Carbon Fiber Reinforced Polymer (CFRP) has been studied numerically and experimentally in a dynamic electrolyte droplet. As an electrolyte, NaCl droplet (0.6 M initial concentration) was used at controlled temperature (24.5°C) relative humidity (83.5%). evaporation of the monitored for 24 hours using Scanning Kelvin Probe (SKP), simulating atmospheric corrosion phenom...

OBJECTIVES Our goal was to investigate the relationship between keloid and telomerase as well as clarifying the influence of Wnt/β-catenin signaling on keloid cell proliferation. METHODS Tissues from 18 keloid patients were collected for further study. Keloid progenitor cells (KPC) and skin progenitor cells (SKP) were both included in this study. Lenti-virus transfection was used to divide ce...

BACKGROUND Impaired wound healing as one of the complications arising from diabetes mellitus is a serious clinical issue. Recently, various cell therapies have been reported for promotion of wound healing. Skin-derived precursor cells (SKPs) are multipotent adult stem cells with the tendency to differentiate into neurons. We investigated the potency of promoting diabetic wound healing by the ap...
