Superantigens stimulate T cells bearing certain TCR beta-chain variable regions when bound to MHC II molecules. We investigated whether the superantigen toxic shock syndrome toxin-1 (TSST1) could induce an antitumor immune response when anchored onto MHC II-negative tumor cells. Our approach was to facilitate association of TSST1 with cell membranes by fusing its coding region to the transmembr...
Highly toxic organophosphorus compounds (OPs) were originally developed for warfare or as agricultural pesticides. Today, OPs represent a serious threat to military personnel and civilians. This study investigates the in vivo decontamination of male Wistar rats percutaneously exposed to paraoxon and two potent nerve agents--soman (GD) and VX. Four commercial detergents were tested as decontamin...
Tympanic membrane (TM) perforation, in particular chronic otitis media, is one of the most common clinical problems in the world and can present with sensorineural healing loss. Here, we explored an approach for TM regeneration where the latent progenitor or stem cells within TM epithelial layers may play an important regulatory role. We showed that potential TM stem cells present highly positi...
Tropomyosin (Tm) is a conserved dimeric coiled-coil protein, which forms polymers that curl around actin filaments in order to regulate actomyosin function. Acetylation of the Tm N-terminal methionine strengthens end-to-end bonds, which enhances actin binding as well as the ability of Tm to regulate myosin motor activity in both muscle and non-muscle cells. In this study we explore the function...
Thrombomodulin (TM), a critical component of the protein C anticoagulant pathway, has previously been localized to endothelial cells (EC), but not smooth muscle cells (SMC) of the blood vessel wall. We demonstrate that cultured rat, bovine, as well as human SMC, but not blood vessel wall smooth muscle tissue, possess significant functional levels of TM and TM mRNA. Cyclic adenosine monophosphat...
Transactional memory (TM) is a promising paradigm for concurrent programming. This paper is an overview of our recent work on defining a theory of TM. We first present a correctness condition of a TM, ensured by most existing TM implementations. Then, we describe two progress properties that characterize the two main classes of TM implementations: obstructionfree and lock-based TMs. We use thes...
OBJECTIVE Ultrasound surveillance of patients with testicular microlithiasis (TM) has been recommended because of the reported association between TM and testicular cancer (TC). The purpose of this review is to summarize what is known about TM and discuss recent recommendations. CONCLUSION The most recent recommendations do not support the use of routine ultrasound surveillance for patients w...
To clarify the relation between systemic and cutaneous vascular endothelial injury in progressive systemic sclerosis (PSS), we examined thrombomodulin (TM) expression in PSS skin lesions immuno-histopathologically and compared it with plasma soluble TM levels measured by specific enzyme-linked immunosorbent assay. The plasma soluble TM level in PSS patients was significantly higher than that of...
