New pyrazolyl-diamine ligands with acridine derivatives at the 4-position of the pyrazolyl ring were synthesized and characterized (L1 and L2). Coordination towards the fac-[M(CO)(3)](+) (M = Re, (99m)Tc) led to complexes fac-[M(CO)(3)(kappa(3)-L)] (L = L1: M = Re1, Tc1; L = L2: M = Re2, Tc2). The interaction of the novel pyrazolyl-diamine ligands (L1 and L2) and rhenium(i) complexes (Re1 and R...
BACKGROUND In women, anorectal infections with Chlamydia trachomatis (CT) are about as common as genital CT, yet the anorectal site remains largely untested in routine care. Anorectal CT frequently co-occurs with genital CT and may thus often be treated co-incidentally. Nevertheless, post-treatment detection of CT at both anatomic sites has been demonstrated. It is unknown whether anorectal CT ...
زمینه: استرس اکسیداتیو شرایطی است که در آن تعادل بین گونههای اکسیژن فعال (ROS) و آنتیاکسیدانها مختل میشود. گلوتاتیون پراکسیداز 1 (GPX-1)، به عنوان یک آنزیم آنتی اکسیدان ROS را طی یک فرایند متوالی از میان میبرد. یکی از پلیمورفیسمهای عملکردی ژن GPX1، پلیمورفیسم Pro198Leu میباشد. هدف از این مطالعه، ارزیابی ارتباط پلیمورفیسم Pro198Leu ژن GPX-1 با سرطان کولورکتال میباشد. مواد و روشها: د...
In bacteria, the DnaG primase is responsible for synthesis of short RNA primers used to initiate chain extension by replicative DNA polymerase(s) during chromosomal replication. Among the proteins with which Escherichia coli DnaG interacts is the single-stranded DNA-binding protein, SSB. The C-terminal hexapeptide motif of SSB (DDDIPF; SSB-Ct) is highly conserved and is known to engage in essen...
A collection of 521 environmental isolates of Vibrio cholerae which were previously examined by the suckling mouse assay and found to be negative for the heat-stable enterotoxin NAG-ST were reassessed by a recently developed DNA probe for NAG-ST. A total of 12 (2.3%) of the isolates hybridized with the NAG-ST probe. By using a cholera toxin (CT) DNA probe, the CT gene was detected in six of the...
In this research, the interaction of [CuL(DMF)], [NiL(DMF)] and [VOL(DMF)] (where L = ((E)-4-((2-amino-5-nitrophenylimino)methyl)benzene-1,3-diol)) complexes derived from tridentate Schiff base ligand with bovine serum albumin (BSA) and DNA was investigated via electronic absorption and fluorescence spectroscopy. The Ultraviolet-Visible (UV-Vis) spectra exhibited an isosbestic point for the com...
Abstract Ferrocene or ferrocenium has been widely studied in the field of organometallic complexes because its stable thermodynamic, kinetic and redox properties. Novel hexaferrocenium tri[hexa(isothiocyanato)iron(III)]trihydroxonium (HexaFc) complex was product from reaction ferrocene, maleic acid ammonium thiocyanate confirmed by elemental analysis CHNS, FTIR single crystal X-ray crystallogra...
Three small insert (300 to approximately 600 bp) sheared genomic libraries were constructed by pipetting and DNase I treatment of soybean DNA. About 15,000 clones from each library were screened for CT- simple sequence repeats (CT-SSRs). The CT-SSRs were abundant in the soybean genome at an estimated frequency of approximately one SSR per 110 kb of genomic DNA. Following the sequencing of 129 p...
هدف از این مطالعه بررسی امکان استفاده از داروهای شناخته شده در درمان سایر بیماریها به عنوان داروهای ضد سرطان است. همچنین با استفاده از این داروها در ساختمان کمپلکس فلز می توان شاخص های دارویی بدست آمده را بررسی نمود. داروی ضد ویروس ایدز(hiv)به نام زیدوودین(azt)انتخاب و.کمپلکس.محلول.در.آب[pt(azt)2]cl2سنتزو به روشهای مختلف فیزیکی و شیمیایی شناسایی گردید. بر هم کنش مقایسه ای این دارو و کمپلکس پلا...
Adduct-induced DNA damage can affect transcription efficiency and DNA replication and repair. We previously investigated the effects of the 3'-next flanking base (G*CT vs G*CA; G*, FABP, N-(2'-deoxyguanosin-8-yl)-4'-fluoro-4-aminobiphenyl; FAF, N-(2'-deoxyguanosin-8-yl)-7-fluoro-2-aminofluorene) on the conformation of arylamine-DNA lesions in relation to E. coli nucleotide excision repair ( Jai...
