conclusions a(h1n1)pdm09 viruses, identified in this study in shiraz, iran, contained 5 site specific mutations and were susceptible to oseltamivir. results our results revealed that a(h1n1)pdm09 viruses present in these samples were susceptible to oseltamivir, and contained 5 site specific mutations (v13g, v106i, v241i, n248d, and n369k) in na gene. these mutations correlated with increasing e...
سرطان نوعی بیماری است که در آن سلول ها توانایی تقسیم و رشد عادی خود را از دست می دهند ازاجتماع این سلول های سرطانی, توده ای به نام تومور ایجاد می شود. مرگ ناشی از سرطان در سال ???? ، ?/? میلیون نفر بوده است که ??%از کل ?? میلیون مرگ در سراسرجهان رابه خوداختصاص میدهد. سرطان کلورکتال که به نام های سرطان کلون یا روده نیز خوانده می شود، در پی رشد سلول های سرطانی در کولون، رکتوم و آپاندیس بروز می...
conclusion prevalence of p. aeruginosa producing esbl and mdr strains from our clinical samples and environment is still low. results the highest resistance rates from the isolated p. aeruginosa were shown against piperacillin, imipenem, cefotaxime, ceftriaxone, gentamicin, ceftazidime, aztreonam, and ciprofloxacin, respectively. seven isolates (9.2%) were esbl producers. more than 30% of the i...
Na(+)/H(+) antiporters are integral membrane proteins that exchange Na(+) for H(+) across the cytoplasmic membrane and many intracellular membranes. They are essential for Na(+), pH and volume homeostasis, which are crucial processes for cell viability. Accordingly, antiporters are important drug targets in humans and underlie salt-resistance in plants. Many Na(+)/H(+) antiporters are tightly r...
The acquisition of neuraminidase (NA) inhibitor resistance by H5N1 influenza viruses has serious clinical implications, as this class of drugs can be an essential component of pandemic control measures. The continuous evolution of the highly pathogenic H5N1 influenza viruses results in the emergence of natural NA gene variations whose impact on viral fitness and NA inhibitor susceptibility are ...
BACKGROUND influenza viruses (IFVs) frequently achieve resistance to antiviral drugs, necessitating the development of compounds with novel mechanisms of action. DAS181 (Fludase), a sialidase fusion protein, may have a reduced potential for generating drug resistance due to its novel host-targeting mechanism of action. METHODS IFV strains B/Maryland/1/59 and A/Victoria/3/75 (H3N2) were subjec...
micrornas (mirnas) are non-coding small rna molecules with 21–25 nucleotides. it plays significant role in control of gene expression at posttranscriptional/translational level. they are commonly dysregulated in human cancers, whereas they may behave either as oncogenes or as tumor-suppressor genes. both genetic and epigenetic events in deregulation of mirna can lead to cancer development. gene...
background: urinary tract infection (uti) is a common cause for diseases in infants. various studies have suggested that infants with uti benefit from a lower rate of breastfeeding compared to control groups. our experimental evidence showed if breastfed infants are infected with a uti, their response to treatment is faster and better. objectives: the aim of this study is to compare bacterial r...
background vancomycin resistant isolates of enterococcous faecium (vre) have previously been reported from tehran hospitals. however, little data were available on the genetic heterogeneity of vre isolates among the iranian population. therefore the emergence of infections with the new clones of vre needs to be investigated. the drug resistance surveillance program at labbafinejad hospital has ...
background immunomodulators and nucleotide analogues have been used globally for the dealing of chronic hepatitis b virus (hbv) infection. however, the development of drug resistance is a major limitation to their long-term effectiveness. objectives the aim of this study was to characterize the hepatitis b virus reverse transcriptase (rt) protein variations among iranian chronic hbv carriers wh...
