Insight into the on/off switch that regulates expression of the MSMEG-3762/63 efflux pump in Mycobacterium smegmatis

Insight into the on/off switch that regulates expression of the MSMEG-3762/63 efflux pump in Mycobacterium smegmatis

Absence of the MSMEG-3762/63 pump enhances membrane potential To evaluate the functional role of MSMEG-3762/63 in membrane potential (Δψ), cytofluorimetric analysis was performed on M. smegmatis (wt), M. smegmatis (ΔMSMEG_3763) and M. smegmatis (ΔMSMEG_3763 pBD04) complemented strain, using the DiOC2 fluorescent carbocyanine dye. DiOC2 exhibits green fluorescence in the monomeric state but shifts toward red …

Investigation of laser wavelength effect on the ablation of enamel and dentin using femtosecond laser pulses

Investigation of laser wavelength effect on the ablation of enamel and dentin using femtosecond laser pulses

Ablation thresholds, rates, and efficiencies Determining ablation thresholds, rates, and efficiency is essential for optimizing femtosecond laser material processing and ensuring consistent results. The ablation threshold is the minimum laser fluence required to start the ablation process, and it is one of the most important parameters in laser material processing. The ablation rate (i.e. the …

Geochronological results from the Zhela Formation volcanics of the Tethyan Himalaya and their implications for the breakup of eastern Gondwana

Geochronological results from the Zhela Formation volcanics of the Tethyan Himalaya and their implications for the breakup of eastern Gondwana

The ages of the sampling strata The zircons are subhedral (40–140 μm long, 20–60 μm wide) with weak oscillatory zoning (Fig. 4a and Supplementary Fig. S1). These characteristics, together with the fact that the Th/U ratios (0.11–1.35; Table 1) are obviously greater than the metamorphic zircon ratio (usually < 0.1), suggest that the zircons are of magmatic origin. Zircon SHRIMP …
