The best-known media gateway control protocols are currently Media Gateway Control Protocol (MGCP) and Megaco/H.248. MGCP, described as informational RFC 2705, has been widely deployed. Megaco/H.248 has evolved from MGCP. It is a single unified protocol that resulted from the cooperation between the Internet Engineering Task Force (IETF) and the International Telecommunication Union (ITU). Mega...

p53 mutations are common in lung cancer. In smoking-associated lung cancer,the occurrence of G:C to T:A transversions at hotspot codons, e.g., 157, 248, 249,and 273, has been linked to the presence of carcinogenic chemicalsin tobacco smoke including polycyclic aromatic hydrocarbons suchas benzo(a)pyrene (BP). In the present study, we have used a highly sensitive mutation assay to determine the ...

The central nervous system (CNS) has very restricted intrinsic regeneration ability under the injury or disease condition. Innovative repair strategies, therefore, are urgently needed to facilitate tissue regeneration and functional recovery. The published tissue repair/regeneration strategies, such as cell and/or drug delivery, has been demonstrated to have some therapeutic effects on experime...

[F]DPA-714 [N,N-diethyl-2-(2-(4-(2[F]-fluoroethoxy)phenyl) 5,7dimethylpyrazolo[1,5a]pyrimidin-3-yl)acetamide] is a new radioligand currently used for imaging the 18-kDa translocator protein in animal models of neuroinflammation and recently in humans. The biodistribution by positron emission tomography (PET) in baboons and the in vitro and in vivo metabolism of [F]DPA-714 were investigated in r...

Aim. A new manufacturing method aiming at to producing more flexible and resistant NiTi endodontic instruments has been recently developed (Hyflex, produced with CM wire). The purpose of the study was to determine whether this new manufacturing method produces NiTi instruments (Hyflex) of superior flexibility and/or superior resistance to cyclic fatigue, when compared with instruments produced ...

results hepatitis b surface antigen (hbsag) was found in 122/3000 (4.1%) prisoners. hepatitis b e antigen (hbeag), anti-hiv, anti-hcv and anti-hiv/anti-hcv were detected in 52/122 (42.6%), 12/122 (10%), 22/122 (18%) and 3/122 (2.4%) prisoners, respectively. the hbv-dna was found in 115/122 (94.3%) prisoners. the most high risk behavior was to utilize the collaborative syringe by injecting drug ...

We study complexified Harmonic Oscillator with a position dependent mass, referred to in the present paper as Exotic Oscillator (EO), in arbitrary dimensions. The real space EO has an interesting dynamics: in the equation of motion the full Hamiltonian operator appears in place of the frequency parameter in a Harmonic Oscillator. We reveal some generic features in the constraint structure of th...

  Background and Objective: The frequency and pattern of eye neoplasms differ in various geographic areas. Our aim was to determine the distribution of patient age, gender, ocular tumor origin, location and histological type in our region. Materials and Methods: In this cross-sectional study, all of the 384 eye globe enucleation cases carried out during a 10-year period in Farabi Medical Cent...

The NanoChip400 system uses multiplex PCR chemistry and electronic microarray detection of influenza A and B viruses; respiratory syncytial viruses A and B; and human parainfluenza virus types 1, 2, and 3. The results obtained with the NanoChip 400 system were compared with those obtained by direct fluorescent-antibody staining (DFA) and real-time PCR with 122 and 130 specimens, respectively. C...
