The Characterization of the Selected Trees Damaged During Severe Weather Episode on the Mountain Avala (Serbia) Using IR Thermography, ICP-OES, and Microbiological Analysis

Slađana Časlav Alagić, Zoran Miroslava Stević, Predrag Branko Jovanić, Ivana Morić, more

International Journal of Environmental Research > 2018 > 12 > 2 > 135-146

Selected plants of white fir and lime, damaged during severe weather episode on the mountain Avala (Serbia) in summer 2014, were analyzed and characterized (including their spatial soil samples) by inductively coupled plasma optical emission spectroscopy (ICP-OES), infrared (IR) thermography, and microbiological method such as enumeration of cultivable microorganisms. The results obtained from chemical...

QSAR modeling of dihydrofolate reductase inhibitors as a therapeutic target for multiresistant bacteria

Jovana B. Veselinović, Vukica Đorđević, Milena Bogdanović, Ivana Morić, more

Structural Chemistry > 2018 > 29 > 2 > 541-551

Antibacterial resistance is a growing public health threat of major concern around the world so development of new therapeutic approaches to prevent bacterial multidrug resistance has become a primary consideration for medicinal chemistry research. QSAR models for the dihydrofolate reductase inhibition with 2,4-diamino-5-(substituted-benzyle)-pyramidine derivatives were developed with further computer-aided...

Heterologous Escherichia coli Expression, Purification and Characterization of the GrmA Aminoglycoside-Resistance Methyltransferase

Ivana Moric, Sanja Bajkic, Miloje Savic, Tatjana Ilic Tomic, more

The Protein Journal > 2009 > 28 > 7-8 > 326-332

The mechanism of resistance to aminoglycosides based on methylation of their target, 16S rRNA, was until recently described only in antibiotic producing microorganisms. However, equivalent methyltransferases have now also been identified among numerous clinical Gram-negative pathogenic isolates. We have cloned, expressed, and purified GrmA, the aminoglycoside-resistance methyltransferase from Micromonospora purpurea...

Aminoglycoside resistance genes sgm and kgmB protect bacterial but not yeast small ribosomal subunits in vitro despite high conservation of the rRNA A-site

Tatjana Ilic Tomic, Ivana Moric, Graeme L. Conn, Branka Vasiljevic

Research in Microbiology > 2008 > 159 > 9-10 > 658-662

The aminoglycoside resistance genes sgm from Micromonospora zionensis and kgmB from Streptomyces tenebrarius were cloned into a yeast expression vector to test whether the encoded prokaryotic methylases can modify the 18S rRNA A-site and thus confer resistance to G-418. Despite the detectable presence of mRNAs in yeast cells, neither G-418-resistant yeast transformants nor positive western blot signals...

Elemental analysis of the Mycobacterium avium phagosome in Balb/c mouse macrophages

Dirk Wagner, Jörg Maser, Ivana Moric, Stefan Vogt, more

Biochemical and Biophysical Research Communications > 2006 > 344 > 4 > 1346-1351

Using a hard X-ray microprobe, we showed recently that in unstimulated peritoneal macrophages from C57BL/6 mice, the phagosome of pathogenic mycobacteria (Mycobacterium tuberculosis and Mycobacterium avium) can accumulate iron. We expanded our studies to the M. avium infection of peritoneal macrophages of Balb/c mice that show a similar degree of M. tuberculosis and M. avium-related chronic disease,...

Use of induced sputum for the diagnosis of influenza and infections in asthma: a comparison of diagnostic techniques

Jodie L. Simpson, Ivana Moric, Peter A.B. Wark, Sebastian L. Johnston, more

Journal of Clinical Virology > 2003 > 26 > 3 > 339 - 346

Background: Influenza (Flu) and respiratory syncytial virus (RSV) are important viral pathogens that cause lower respiratory tract infections and severe exacerbations of asthma. Molecular biological techniques are permitting a rapid and accurate diagnosis of infections caused by respiratory pathogens, and have typically been applied to upper respiratory samples. Sputum induction provides an opportunity...

DNA architecture and transcriptional regulation of the Escherichia coli penicillin amidase (pac) gene

Nataša Stojćević, Ivana Morić, Jelena Begović, Saša Radoja, more

Biomolecular Engineering > 2001 > 17 > 3 > 113 - 117

The transcriptional regulation of Escherichia coli ATCC11105 penicillin amidase (pac) gene was studied by modifying DNA sequences responsible for promoter activation by cyclic AMP receptor protein (CRP). The nucleotide sequence of the 5'-flanking region of the pac gene contains putative tandem CRP binding sites positioned at -69/-70 and at -111/-112 with respect to the transcriptional start site....

DNA region responsible for transcriptional regulation of the Escherichia coli penicillin amidase (pac) gene by CRP and PAA

Saša Radoja, Olivera Francetić, Nataša Stojićević, Ivana Morić, more

Genetic Analysis: Biomolecular Engineering > 1999 > 15 > 6 > 235-238

Transcriptional regulation of Escherichia coli ATCC11105 penicillin amidase gene (pac) by cAMP receptor protein (CRP) and phenylacetic acid (PAA) was studied by using operon fusions with divergent reporter gene (lacZ, and phoA) constructs. A 150 bp DNA segment essential for the regulation of pac gene transcription by CRP and PAA was defined.
