Understanding the antibiotic susceptibility of Salmonella enterica is important both from a clinical treatment and a public health perspective. The emergence of extended spectrum ß-lactamases (ESßLs) and AmpC ß-lactamases in S. enterica is important, as this will limit treatment options and could provide a strain with a significant selective advantage. The aim of the study was to screen isolate...
Odontogenic keratocyst is now designated by the World Health Organization as a keratocystic odontogenic tumor (KCOT). According to recent reports Wnt pathway and ß-catenin are involved in the pathogenesis of the majority of odontogenic and neoplastic lesions. The aim of this study was to evaluate the expression of ß-catenin in KCOT and compare it with those of dentigerous cyst and ameloblastoma...
The proper localization of ß-actin mRNA and protein is essential for growth cone guidance and axon elongation in cultured neurons. In addition, decreased levels of ß-actin mRNA and protein have been identified in the growth cones of motor neurons cultured from a mouse model of Spinal Muscular Atrophy (SMA), suggesting that ß-actin loss-of-function at growth cones or pre-synaptic nerve terminals...
Burnout is associated with poor mental and physical functioning and high costs for societies. Personality attributes may critically increase the risk of personal burnout. We specifically examined whether narcissism associates with personal burnout in a working population. We studied n=1,461 employees (mean age 41.3 ± 9.4 yr, 52% men) drawn from a random sample of a pharmaceutical company in Ger...
The interaction of brilliant green with herring sperm DNA was investigated in detail by spectrometric methods in γ-cyclodextrin systems. On the condition of physiological pH, brilliant green prefers to form the 1:1 inclusion complex with γ-cyclodextrin.All the evidences indicated that the binding modes between γ-cyclode...
b-cyclodextrin glucosyl transferase (b-CGTase) hydrolyses starch to produce b-cyclodextrin by transglycosylation (cyclization) activity. The conventional method for detection of b-CGTase activity is based on detecting starch hydrolysis by iodine staining. This method reveals all amylolytic enzymes, but can not discriminate them. In the present study, we introduce a new method for specific detec...
Introduction: Beta-actin is a housekeeping gene, which is used as an internal standard in various biological studies. Recently, it was reported that the expression of commonly used housekeeping genes including ß–actin changes in disease states or under certain experimental conditions. Based on the reports about the effects of sex hormones on the expression of the ß- actin gene, in this study...
Cyclodextrin (CD) are cyclic oligosaccharides consisting of glucopyranosyl units linked by α-(1,4) bonds. The widely used natural cyclodextrins are α-, βand γ-cyclodextrin consisting of 6, 7 and 8 glucopyranose units, respectively. The cyclodextrin molecules have a unique structure with a hydrophobic cavity and a hydrophilic surface which can form inclusion complex with a wide variety of guests...
Amphiphilic γ-cyclodextrin–fullerene 2:1 complexes (C L FC H complexes) were prepared by high-speed vibration milling of lipophilic tail-grafted γ-cyclodextrin (γ-CD), hydrophilic γ-CD and fullerene C 60 . The transamidation γ-CD–fullerene complex having two...
Novel (S)-camptothecin-dextran polymers were obtained by "click" grafting of azide-modified (S)-camptothecin and alkyne-modified dextrans. Two series based on 10 kDa and 70 kDa dextrans were prepared with a degree of substitution of (S)-camptothecin between 3.1 and 10.2%. The binding properties with β-cyclodextrin and β-cyclodextrin polymers were measured by isothermal titration calorimetry and...
