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 ...

OBJECTIVES Brucellosis is a systemic disease with a wide spectrum of clinical manifestations. This study aimed to determine the seroprevalence of brucellosis in human immunodeficiency virus (HIV) infected patients in Hamadan Province in the west of Iran. METHODS A total of 157 HIV-infected patients were screened through standard serological tests, including Wright's test, Coombs' Wright test,...

قدرت تفکیک دستگاه طیف‌نگار جرمی به صورت مستقیم شدت یون خروجی و انرژی آن بستگی دارد. مقدار تولید شده جریان باریکه الکترونی وابسته است. از جمله وظایف مدار کنترل چشمه برخورد تنظیم برای رسیدن بهینه می‌باشد. در ساخت پارامترهایی نظیر تثبیت آن، دقیق پتانسل الکتریکی لنز الکترودهای یونی بسیار حایز اهمیت این مقاله با قابلیت انتشار الکترون، پتانسیل نقاط طراحی ساخته شد. کنترلر بر روی طیف نگار 44Varian MAT ...

background and objective: brucellosis is a zoonotic disease of worldwide distribution and has great economic importance. despite its control in many countries, it remains endemic in iran. brucellosis was investigated in many high risk occupational groups; however, few studies on the prevalence of brucellosis among blood donors are available. to determine the seroprevalence of brucellosis antibo...
