We have used WFPC2 V RI observations to calculate the distances to three nearby galaxies, NGC 4214, UGC 685, and UGC 5456 using the tip of the red giant branch method. Our values for NGC 4214 (2.94 ± 0.18 Mpc) and UGC 685 (4.79 ± 0.30 Mpc) are the most precise measurementes of the distances to these objects ever made. For UGC 5456 the data do not allow us to reach a decisive conclusion since th...

CpG oligodeoxynucleotides (ODNs) upregulate the interleukin-21 receptor (IL21R) and enhance IL-21-mediated cytotoxicity in chronic lymphocytic leukemia (CLL) B cells. We demonstrate that treatment of CLL B cells with the ODN CpG-685 leads to increased IL21R expression, and that this increased expression enhances the effects of IL-21 treatment as evidenced by increased phosphorylation of JAK1, S...

Polyhydroxyalkanoates (PHAs) are a class of biopolymers with numerous applications, but the high cost of production has prevented their use. To reduce this cost, there is a prospect for strains with a high PHA production and the ability to grow in low-cost by-products. In this context, the objective of this work was to evaluate marine bacteria capable of producing PHA. Using Nile red, 30 organi...

Steady state LIF spectra using 488 nm of cw Ar + laser and 355 nm of pulsed Nd:YAG laser, fluorescence induction kinetics using 488 nm laser light were studied in wheat seedlings exposed to increasing cadmium (Cd) concentrations (0.01, 0.1, 1.0 and 2.0 mM). In addition, some growth parameters and pigment content were also measured. The LIF spectra of the leaves exhibited two characteristic band...

Na+/Ca2+exchange is the primary mechanism mediating Ca2+ efflux from cardiac myocytes during diastole and, thus, can prominently influence contractile force. In addition to transporting Na+and Ca2+, the exchanger is also regulated by these ions. Although structure-function studies have identified protein regions of the exchanger subserving these regulatory processes, their physiological importa...

We attempt to present a multiwavelength variability and correlation study as well detailed multi-waveband spectral characteristics of the May 2021 $\gamma$-ray flare blazar source TXS 1700+685. The multi-wavelength observation from \textit{Fermi}-LAT, \textit{Swift}-XRT/UVOT radio archival data are used for our spectro-temporal investigation. estimate time-scale flux doubling time in different ...

The gradual insertion method for direct calculation of the chemical potential by molecular simulation is applied in the NpT ensemble to different quadrupolar two-centre LennardJones fluids at high density state points. The results agree well with Widom’s test particle insertion but show at very high densities significantly smaller statistical uncertainties. The gradual insertion method, which i...
