this is the first description of the polymorphisms of arylalkylamine-n-acetyltransferase (aa-nat) gene in indian goats with different reproductive traits (twinning percentage and age of sexual maturity). based on the important role of aa-nat in reproduction, it is considered as a possible candidate gene for this trait. two novel synonymous snps, c825t (exon2) and c1249t (exon3) were identified....

ZigBee has been considered as one of the promising communication protocols for low-rate wireless personal area networks. Among the well-known ZigBee topologies, ZigBee cluster-tree is especially suitable for wireless sensor applications with its supporting of power-saving operation and light-weight routing. Due to the restriction of configuration parameters, some devices could be prohibited to ...

This specification defines an experimental usage of the Session Traversal Utilities for NAT (STUN) Protocol that discovers the presence and current behavior of NATs and firewalls between the STUN client and the STUN server.

PURPOSE Dynamic day-night changes in melatonin synthesis are regulated by changes in the activity of serotonin N-acetyltransferase (arylalkylamine N-acetyltransferase [AA-NAT]). Similarly, a light-induced decrease in AA-NAT activity at night rapidly suppresses melatonin synthesis. The purpose of the current study was to test the hypothesis that in vivo changes of AA-NAT activity in chicken reti...
