the drb3 gene is a highly polymorphic major histocompatibility complex (mhc) class ii gene and plays an important role in variability of immune responsiveness and disease resistance. in the present study, the mhc class ii drb3 gene in water buffalo (bubalus bubalis) populations from northwest regions of iran was investigated through pcr-sscp. genomic dna was extracted from whole blood samples c...

We present a low-loss, compact, polarization insensitive 3-dB optical power-splitter for submicron silicon waveguides. The splitter is optimized over broad wavelength span ranging from 1300 to 1700 nm through finite difference time domain simulations. junction footprint only 1.8 × 1.3 ?m, which smaller than previously reported broadband multimode splitters. Furthermore, the demonstrated device ...

background and aims: virus infections represent some of the most important diseases of lily, plants because of the devastating effects caused to the crops and the absence of effective treatments. a survey for virus diseases of lilies, revealed the occurrence of cucumber mosaic virus (cmv) in plants growing in tehran province, iran. materials and methods: during 2013, 50 lily samples with virus-...

background and objectives:   many surface proteins are implicated in nasopharyngeal colonization and pathogenesis of streptococcus pneumoniae . some of these factors are candidate antigens for protein based vaccines. new vaccine designs focus on the surface proteins (e. g., pspa and pspc ) and also cytolysin, and pneumolysin. in this study, 3 key virulence genes, lyta , pspc , and rrga , which ...

The gammaherpesvirus immediate-early genes are critical regulators of virus replication and reactivation from latency. Rta, encoded by gene 50, serves as the major transactivator of the lytic program and is highly conserved among all the gammaherpesviruses, including Epstein-Barr virus, Kaposi's sarcoma-associated herpesvirus, and murine gammaherpesvirus 68 (gammaHV68). Introduction of a transl...

Two modes are being considered for a 50 on 50-GeV muon collider: one being a high-luminosity ring with broad momentum acceptance (dp/p of ∼ 0.12%, rms) and the other lower luminosity with narrow momentum acceptance (dp/p of ∼ 0.003%, rms), or Higgs Factory. To reach the design luminosities, the value of beta at collision in the two rings must be 4 cm and 14 cm, respectively. In addition, the bu...
