Upon environmental changes, bacteria reschedule gene expression by directing alternative sigma factors to core RNA polymerase (RNAP). This sigma factor switch is achieved by regulating relative amounts of alternative sigmas and by decreasing the competitiveness of the dominant housekeeping sigma(70). Here we report that during stationary phase, the unorthodox Crl regulator supports a specific s...

The sigma-receptor, a broadly distributed integral membrane protein with a novel structure, is known to modulate various voltage-gated K(+) and Ca(2+) channels through a mechanism that involves neither G proteins nor phosphorylation. The present study investigated the modulation of the heart voltage-gated Na(+) channel (Na(v)1.5) by sigma-receptors. The sigma(1)-receptor ligands [SKF-10047 and ...

A continuous-time particle system on the real line satisfying branching property and an exponential integrability condition is called a L\'evy process, its law characterized by triplet $(\sigma^2,a,\Lambda)$. We obtain necessary sufficient for convergence of derivative martingale such process to non-trivial limit in terms This extends previously known results Brownian motions random walks. To t...

Bacterial sigma (sigma) factors are an essential component of RNA polymerase and determine promoter selectivity. The substitution of one sigma factor for another can redirect some or all of the RNA polymerase in a cell to activate the transcription of genes that would otherwise be silent. As a class, alternative sigma factors play key roles in coordinating gene transcription during various stre...

The Fisher gAlaxy suRvey cOde ($\texttt{FARO}$) is a new public Python code that computes the matrix for galaxy surveys observables. observables considered are linear multitracer 3D power spectrum, convergence spectrum weak lensing, and correlation between distribution convergence. allows tomographic model-independent analysis in which, scale-independent growth, following functions of redshift ...

in the present paper, we introduce some new sequence spaces derived by riesz mean and the notions of almost and strongly almost convergence in a real 2-normed space. some topological properties of these spaces are investigated. further, new concepts of statistical convergence which will be called weighted almost statistical convergence, almost statistical convergence and statistical convergence...

Cruz Biotechnology), anti-FLAG (M2; Sigma Chemical Co., St. Louis, MO), anti-β-actin (AC-15; Sigma), and anti-α-tubulin (B-5-1-2; Sigma Chemical Co.) were used. Anti-Synoviolin monoclonal antibody (10Da) was reported previously (Amano et al., 2003). Cycloheximide (Sigma Chemical Co., 100μg/mL) was used for the chase experiment of p53. Camptothecine (Sigma, 0.5 mM), and actinomycin D (Sigma Chem...
