Ubiquitin-specific protease 7 (USP7) is a deubiquitinating enzyme responsible for the regulation of key human oncoproteins and tumor suppressors including Mdm2 and p53, respectively. Unlike other members of the USP family of proteases, the isolated catalytic domain of USP7 adopts an enzymatically inactive conformation that has been well characterized using X-ray crystallography. The catalytic domain also samples an active conformation, which has only been captured upon USP7 substrate-binding.

Intravenous self-administration (IVSA) is a behavioral method of voluntary drug intake in animal models which is used to study the reinforcing effects of drugs of abuse. It is considered to have greater face validity in the study of substance use and abuse than other assays, and thus, allows for valuable insight into the neurobiological basis of addiction, and the development of substance abuse disorders. The technique typically involves surgically inserting a catheter into the jugular vein, which enables the infusion of drug solution after the performance of a desired operant behavior.

Ubiquitin specific protease 7 (USP7) is a deubiquitinating enzyme, which removes ubiquitin tag from numerous protein substrates involved in diverse cellular processes such as cell cycle regulation, apoptosis and DNA damage response. USP7 affects stability, interaction network and cellular localization of its cellular and viral substrates by controlling their ubiquitination status. The large 41 kDa catalytic domain of USP7 harbors the active site of the enzyme.

Background And Objectives: We aimed to determine the risk of complications during cutaneous surgery for the perioperative discontinuation in comparison to the continuation of antithrombotic agents and the bridging of vitamin K antagonists with heparin in comparison to their continuation.

Methods: We conducted a systematic review, searching three databases for eligible studies. Methods followed the Cochrane Handbook.
