The homodimeric tetracycline repressor (TetR) regulates resistance to the antibiotic tetracycline at the transcriptional level. TetR binds in the absence of Tc to palindromic operator sequences utilizing two helix-turn-helix (HTH) motifs. If the tetracycline-Mg2+ complex [MgTc]+ enters two identical binding tunnels buried within the TetR homodimer, a conformational change takes place, and the i...
Powdery mildew (Podosphaera aphanis) is a destructive and widespread disease of strawberry (Fragaria × ananassa), especially when susceptible cultivars are grown in high plastic tunnels or glasshouses. Many powdery mildews thrive humid environments but free water films on plant surfaces can inhibit conidial germination some species. We hypothesized that P. aphanis might be directly suppressed b...
Introduction: Plaque control by mechanical method is not sufficient and mouthrinses are highly recomended for patients. Some studies have shown that both of alcohol and alcohol free mouthrinses can reduce the microhardness of restorative materials. This study aimed to investigate the effect of three commercial mouthrinses on the microhardness of four different composite resin. Methods: 60 spec...
A hydrogeophysical field experiment was conducted on a karst hydrosystem in the south of France to investigate groundwater transfer and storage variability at scale few hundred meters. 200-m-long N/S tunnel going through limestone provided unique opportunity set up measurements with original configurations inside unsaturated zone. Three geophysical methods were used: gravimetry, electrical, sei...
