The radiative decay νH → νL+γ of massive neutrinos is analyzed in the framework of the standard model with lepton mixing for very strong magnetic fields B ≫ Bcr = me/e ∼ 4.14 × 10 G. The analysis is based on the approximate decay amplitude obtained by Gvozdev et al. Numerical results as well as analytical approximations for the decay rate are obtained for energies of the initial neutrino below ...

We set limits on the magnetic moment and charge radius of the tau neutrino by examining an extra contribution to the electroweak process e+e− → ννγ using VENUS, TOPAZ and AMY results. We find that κ(ντ ) < 9.1 × 10−6 (i.e. μ(ντ ) < 9.1 × 10μB , μB = e/2me) and 〈r2〉 < 3.1 × 10−31cm2 with Poisson statistics by combining their results. Whereas, similar to this method, with the Unified Approach we ...

Addition of 1 equiv of [HNMe2Ph]BAr4 (Ar ) 3,5-(CF3)2C6H3) to Mo(NAr)(CHCMe2Ph)(Pyrrolide)2 (Pyrrolide ) parent pyrrolide (Pyr) or 2,5-dimethylpyrrolide (Me2Pyr)) species in THF produced [Mo(NAr)(CHCMe2Ph)(Pyrrolide)(THF)x]BAr4 species (x ) 2 for Me2Pyr (1b) or 3 (1a) for Pyr; Ar ) 2,6-diisopropylphenyl). [Mo(NAr)(CHCMe2Ph)(Me2Pyr)(2,4-lutidine)]BAr4 (1c) was formed upon addition of 2,4-lutidin...

BACKGROUND AND OBJECTIVES Brucellosis is a zoonotic disease and it's still endemic in Iran. There are some reports regarding brucellosis infection in family members sharing same risk factors and remain unrecognized. However, few studies on the importance of family screening are available. We aimed to screen household members of index cases with acute brucellosis for detecting additional unrecog...

Molecular beacons (MBs) have shown great potential for the imaging of RNAs within single living cells; however, the ability to perform accurate measurements of RNA expression can be hampered by false-positives resulting from nonspecific interactions and/or nuclease degradation. These false-positives could potentially be avoided by introducing chemically modified oligonucleotides into the MB des...

BACKGROUND Brucellosis is a zoonotic infection which is endemic in many countries. It is a multisystem disease which may present with a broad spectrum of clinical manifestations and complications. Neurobrucellosis is an uncommon complication of brucellosis. CASE PRESENTATION A 25-year-old woman with a history of lupus for 5 months referred to the emergency ward of Shahid Beheshti Hospital of ...

7,8-Diaminopelargonic acid (DAPA) aminotransferase is an enzyme of the biotin biosynthetic pathway that plays an essential role in Mycobacterium tuberculosis virulence. Inhibition of this enzyme is a potential strategy to combat this microorganism, the causative agent of tuberculosis. To identify new inhibitors as potential drugs, a simple enzymatic assay for high-throughput screening (HTS) is ...
