Evaluation of the impact and need for use of a safety guidewire during ureteroscopy. | The routine use of a "safety" guidewire adjacent to the ureteroscope during upper tract endoscopy is advocated in surgical texts and by many endourologists. Our experience has led us to theorize that a safety guidewire complicates ureteroscopy by providing resistance to introduction of the endoscope and by creating an ... | 18,721,045 |
Application of high-mobility-group-A proteins increases the proliferative activity of chondrocytes in vitro. | The low capability of self-repair in hyaline cartilage tissue and chondrocytes de-differentiating when grown in vitro (e.g., for tissue engineering approaches) limits articular cartilage repair. It has been shown that the embryonic architectural transcription factors of the high-mobility-group-A (HMGA) protein family a... | 18,721,076 |

Visual attention during virtual social situations depends on social anxiety. | Theories of anxiety propose that people with phobias involuntarily allocate their attention first toward threatening stimuli and then away from these stimuli. Therefore, the current study assessed attention toward and away of social cues in virtual fear-relevant situations. More specifically, open visual attention was ... | 18,721,090 |
Defining cyberbullying: a qualitative research into the perceptions of youngsters. | Data from 53 focus groups, which involved students from 10 to 18 years old, show that youngsters often interpret "cyberbullying" as "Internet bullying" and associate the phenomenon with a wide range of practices. In order to be considered "true" cyberbullying, these practices must meet several criteria. They should be ... | 18,721,100 |
Clinical development of metformin extended-release tablets for type 2 diabetes: an overview. | Glumetz (Depomed, Inc., Menlo Park, CA, USA) is a recently approved gastric retentive extended-release formulation of metformin (M-ER) that provides effective, sustained and well-tolerated glycemic control with once daily administration. Pharmacokinetic studies have demonstrated a similar bioavailability of M-ER admini... | 18,721,117 |
Genetically modified adenoviral vector with the protein transduction domain of Tat improves gene transfer to CAR-deficient cells. | The transduction efficiency of Ad (adenovirus) depends, to some extent, on the expression level of CAR (coxsackievirus and Ad receptor) of a target cell. The low level of CAR on the cell surface is a potential barrier to efficient gene transfer. To overcome this problem, PTD.AdeGFP (where eGFP is enhanced green fluores... | 18,721,127 |
Characterization of mutations in crucial residues around the Q(o) binding site of the cytochrome bc complex from Paracoccus denitrificans. | The protonation state of residues around the Q(o) binding site of the cytochrome bc(1) complex from Paracoccus denitrificans and their interaction with bound quinone(s) was studied by a combined electrochemical and FTIR difference spectroscopic approach. Site-directed mutations of two groups of conserved residues were ... | 18,721,136 |
Probing the rotor subunit interface of the ATP synthase from Ilyobacter tartaricus. | The interaction between the c(11)ring and the gammaepsilon complex, forming the rotor of the Ilyobacter tartaricus ATP synthase, was probed by surface plasmon resonance spectroscopy and in vitro reconstitution analysis. The results provide, for the first time, a direct and quantitative assessment of the stability of th... | 18,721,138 |
Anaerobic degradation of long-chain alkylamines by a denitrifying Pseudomonas stutzeri. | The anaerobic degradation of tetradecylamine and other long-chain alkylamines by a newly isolated denitrifying bacterium was studied. Strain ZN6 was isolated from a mixture of soil and active sludge and was identified as representing Pseudomonas stutzeri, based on partial 16S rRNA gene sequence analysis. Strain ZN6 was... | 18,721,145 |
Pathological role of CD44 on NKT cells in carbon tetrachloride-mediated liver injury. | CD44 has a variety of functions in immune regulation and signal transduction. Although CD44 is involved in the induction of several inflammatory diseases, it remains unknown whether CD44-targeting therapies are useful for liver diseases. Here, we examined whether CD44 blockade is effective in a chemical-induced liver i... | 18,721,153 |
How prominent are patient-reported outcomes in clinical trials of dermatological treatments? | Assessment of symptoms or disease improvement by study participants is an important aspect of assessing new dermatological therapies in clinical trials, especially for chronic skin diseases that lack objective severity markers. We sought to determine the frequency and prominence of reporting of participants' subjective... | 18,721,190 |
Effect of root surface treatment with propolis and fluoride in delayed tooth replantation in rats. | Replantation is an acceptable option for treatment of an avulsed permanent tooth. Nevertheless, an extended extraoral period damages the periodontal ligament and results in external root resorption. The purpose of this study was to assess by histologic and histometric analysis, the influence of propolis 15% (natural re... | 18,721,196 |
Endogenous oxalogenesis after acute intravenous loading with ethylene glycol or glycine in rats receiving standard and vitamin B6-deficient diets. | The effect on endogenous oxalate synthesis of acute intravenous loading with ethylene glycol or glycine was investigated in rats on a standard or a vitamin B6-deficient diet. Twenty-four male Wistar rats weighing approximately 180 g were randomly divided into ethylene glycol and glycine groups of 12 animals each. These... | 18,721,203 |
Induction of a protective immune response against swine Chlamydophila abortus infection in mice following co-vaccination of omp-1 DNA with recombinant MOMP. | Chlamydophila abortus is the causative agent of abortion in pigs and pregnant women. Seroconversion rates were arranged from 11% to 80% in piglets and sows in China. These very high rates illustrate the scale of the problem in China and highlight the urgent need for the development of a C. abortus vaccine. An efficacio... | 18,721,226 |
