Introduction: Human T-cell lymphotropic virus (HTLV), is a member of the retroviridae family. Infection with this virus leads to adult T-cell leukemia (ATL) and tropical spastic paraparesis (TSP). HTLV is endemic in Japan, parts of central Africa, Caribbean basin and Iran (Mashhad). Transmission routes of HTLV are believed to be from mother to child, especially during breastfeeding, sexual con...
Optimally doped silver selenide and silver telluride exhibit linear positive magnetoresistance over decades in magnetic field and on a scale comparable to the colossal magnetoresistance compounds. We use hydrostatic pressure to smoothly alter the band structure of Ag-rich and Ag-deficient samples of semiconducting Ag(2 +/-delta)Te of fixed stoichiometry and disorder. We find that the magnetores...
In this research, silver nanoparticles (Ag NPs) were prepared by a low-cost, rapid, simple and ecofriendly approach using Grape fruit extract as a novel natural reducing and stabilizing agent. The product was characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy-dispersive X-...

ulations must be considered. We totally agree with his arguments. His constructive, detailed technical explanations should be tested thoroughly by the manufacturers of Ag/Cu ionization systems and taken into consideration in future experiments. Dr. Lin’s main scientific point is that the data we presented in our paper do not support the claim that Legionella developed resistance to silver. He a...
The aim of this study was to investigate the diagnostic value of the serum markers HBsAg and HBeAg and PreS1 protein (PreS1-Ag) in quantifying the levels of hepatitis B virus (HBV) DNA in patients with chronic hepatitis B (CHB). One thousand CHB patients were recruited from Beijing You'an Hospital between June and December 2012. Serum HBsAg and HBeAg levels were detected by electrochemiluminesc...
Background: As nanoparticles have multiple applications, there are many different methods for the production of silver nanoparticles (Ag-NPs). Recently, plants are being used in the synthesis of nanoparticles, due to their cost- effectiveness and eco-friendliness approach. In this study, the biosynthesis of silver nanoparticles using extract of Citrus aurantium for its antimicrobial properties ...
در این تحقیق واکنش تشکیل کمپلکس بین کاتیون های tl+، ag+ و +2pb با 2و6-دی(فوران-2ایل)-4-(4-متوکسی فنیل)پیریدین (dfmp) به عنوان یک لیگاند سنتزی جدید در سیستم های دو جزئی استونیتریل(an)–آب(o2h)و متانول(meoh)–آب(o2h)در دماهای مختلف بوسیله تکنیک هدایت سنجی مورد مطالعه قرار گرفت.
Since the dental implant/abutment interface cannot totally seal the passage of microorganisms, the interior of implant becomes a reservoir of pathogenic microorganisms that produce and maintain chronic inflammation in the tissues around implants. Silver nanoparticles (nano-Ag) are potent and broad-spectrum antimicrobial agents. The aim of this study was to evaluate the capacity of the nano-Ag t...
TWO DISTINCT VIRAL ANTIGENS ARE ASSOCIATED WITH THE HEPATITIS B VIRUS: the hepatitis B surface antigen (HB(s)Ag, Australia antigen) and the hepatitis B core antigen (HB(c)Ag). HB(s)Ag, purified from the serum of asymptomatic human HB(s)Ag carriers, and HB(c)Ag, purified from the liver of a chimpanzee acutely infected with hepatitis B virus, were examined by serological and immune electron micro...
