Session Traversal Utilities for NAT (STUN) is a lightweight protocol that serves as a tool for application protocols in dealing with NAT traversal. It allows a client to determine the IP address and port Rosenberg, et al. Expires September 6, 2007 [Page 1] Internet-Draft STUN March 2007 allocated to them by a NAT and to keep NAT bindings open. It can also serve as a check for connectivity betwe...

In this report we have analyzed the role of antisense transcription in the control of LEF1 transcription factor expression. A natural antisense transcript (NAT) is transcribed from a promoter present in the first intron of LEF1 gene and undergoes splicing in mesenchymal cells. Although this locus is silent in epithelial cells, and neither NAT transcript nor LEF1 mRNA are expressed, in cell line...

In September 2016, the world lost a brilliant scientist and I lost my dearest mentor. It was thirty years ago when I first met Nat Durlach in his office on the seventh floor of MIT’s Research Laboratory of Electronics. My academic advisor suggested that I talk to Nat about research. I did and thus began a very rewarding journal of learning and discovery under the guidance of Nat. Nat didn’t exa...

Natalizumab (NAT) was the first monoclonal antibody to be approved for the treatment of relapsing-remitting multiple sclerosis (RRMS). While pivotal and postmarketing studies have showed considerable and sustained efficacy of NAT in RRMS, the increasing incidence of therapy-associated progressive multifocal leukoencephalopathy (PML), a brain infection caused by the John Cunningham virus (JCV), ...

The circadian rhythms in melatonin production in the chicken pineal gland and retina reflect changes in the activity of serotonin N-acetyltransferase (arylalkylamine N-acetyltransferase; AA-NAT; EC 2.3.1.87). Here we determined that the chicken AA-NAT mRNA is detectable in follicular pineal cells and retinal photoreceptors and that it exhibits a circadian rhythm, with peak levels at night. AA-N...

Extended Abstract Fibonacci-type sequences are probably most famous for their recursive definition. The classical one, as F ib(n) =      0, if n = 0, 1, if n = 1, F ib(n − 1) + F ib(n − 2), otherwise, (1) however very simple formulated in natural language, caused some troubles during its formalization in [1]. definition let n be Nat; func Fib (n)-> Nat means :: PRE_FF:def 1 ex fib being Fu...

Nocturnal melatonin production is reportedly controlled by the rhythms of serotonin N-acetyltransferase (NAT, or arylalkylamine N-acetyltransferase). While analyzing the melatonin synthetic pathways of Long Evans cinnamon (LEC) rats mutant for PINA, a pineal night-specific ATPase defective in Wilson disease, we discovered that NAT activity and protein levels are greatly reduced in LEC rats, and...

NAT-PT is one important technology for IPv4 to IPv6 transition by mapping protocols and addresses to enable communication between IPv4-only and IPv6-only networks. However, traditional NAT-PT gateways have limits in scalability, resilience and performance. This paper presents two approaches, NAT-based and DNS-based, for load-balance and fault-tolerance to address such limits. Our implementation...

Latent M. tuberculosis infection presents one of the major obstacles in the global eradication of tuberculosis (TB). Cholesterol plays a critical role in the persistence of M. tuberculosis within the macrophage during latent infection. Catabolism of cholesterol contributes to the pool of propionyl-CoA, a precursor that is incorporated into cell-wall lipids. Arylamine N-acetyltransferase (NAT) i...
