Two-way identity authentication is the basis of secure communication in a distributed application environment. A trusted third party (TTP) is needed while PKI is not applicable, and the design of authentication protocols with TTP is a complicate and challenging task. This paper examines the characteristics of the security of authentication protocols with TTP, summarizes the essential factors of...
The activities of RNA-binding proteins are perturbed in several pathological conditions, including cancer. These proteins include tristetraprolin (TTP, ZFP36) and HuR (ELAVL1), which respectively promote the decay or stability of adenylate-uridylate-rich (AU-rich) mRNAs. Here, we demonstrated that increased stabilization and subsequent over-expression of HuR mRNA were coupled to TTP deficiency....
Thrombotic thrombocytopenic purpura (TTP) is caused by the persistence of the highly reactive high-molecular-weight multimers of von Willebrand factor (VWF) due to deficiency of the specific VWF-cleaving protease (VWF-CP) ADAMTS13, resulting in microangiopathic disease. The acquired form is caused by autoantibodies against VWF-CP, whereas homozygous or compound heterozygous mutations of ADAMTS1...
Idiopathic thrombotic thrombocytopenic purpura (TTP) is a disease characterized by the apoptotic injury of all microvascular endothelial cells (MVEC) except those of pulmonary origin. It notably also spares EC of large vessel origin. It is fatal unless treated with plasma exchange. The EC lineage restriction of the apoptotic lesions in vivo is reproduced in vitro following exposure of primary h...
In patients with thrombotic thrombocytopenic purpura (TTP), excessive intravascular platelet aggregation has been associated with appearance in plasma of unusually large von Willebrand factor (vWF) multimers. These extremely adhesive vWF multimers may arise due to deficiency of a "depolymerase" cleaving vWF to smaller molecular forms, either by reducing the interdimeric disulfide bridges or by ...
Post-transcriptional regulation plays a central role in cell differentiation and proliferation. Among the regulatory factors involved in this mechanism, Tristetraprolin (ZFP36 or TTP) is the prototype of a family of RNA-binding proteins that bind to adenylate and uridylate (AU)-rich sequences in the 3'UTR of mRNAs, which promotes their physiological decay. Here, we investigated whether TTP corr...
Thrombotic thrombocytopenic purpura (TTP) is a disorder of blood coagulation that presents classically with the pentad of fever, thrombocytopenia, microangiopathic hemolytic anemia, renal dysfunction and mental status changes. However, the clinical presentation can be quite variable making the diagnosis difficult in many cases. "Hyaline" microthrombi composed primarily of platelets and Von Will...
Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening thrombotic microangiopathy which causes significant morbidity and mortality unless promptly recognized and treated. The underlying pathogenesis of TTP is a severe deficiency in ADAMTS13 activity, a metalloprotease that cleaves ultralarge von Willebrand factor multimers. This deficiency is either autoantibody mediated (acquire...
Thrombotic thrombocytopenic purpura (TTP) is a hematological disease characterized by microangiopathic hemolytic anemia and thrombocytopenia. Although the link between ADAMTS13 deficiency and idiopathic TTP has been well-established, the role of trimethoprim-sulfamethoxazole (TMP-SMX) in the pathogenesis of TTP is not yet well elucidated. To the best of our knowledge, there have been only two p...
This paper addresses the development of fault-tolerant distributed real-time systems using the TTP protocol. It’s a protocol-specific characteristic that a TTP real-time system only works when all nodes are connected to the bus system. This is a severe obstacle for the projectability of such real-time systems since system parts are often developed by external partners of the supply industry. On...
