BODIPY-based dye for no-wash live-cell staining and imaging

BioTechniques, 2017
In nonpolar solvents, hydrophobic organic fluorophores often show bright fluorescence, whereas in polar media, they usually suffer from aggregation-caused quenching (ACQ).

L^p inequalities for polar derivatives of polynomials [PDF]

Mathematical Inequalities & Applications, 2000
Let \(p(z)=a_0+a_1z+ \cdots+ a_nz^n\) be a polynomial of degree \(n\) and let for fixed \(\alpha\in\mathbb{C}\) \[ D_\alpha p(z):= np(z)+(\alpha-z)p'(z) \] denote the polar derivative of \(p(z)\) with respect to \(\alpha\). In this paper some inequalities for such polar derivatives are presented. In particular it is proved: Theorem.

Neuartige discotisch-flüssigkristalline, polare Monothioscyllitol-Derivate [1,2] / Novel Discotic Liquid Crystalline, Polar Monothioscyllitol Derivatives [1,2]

Zeitschrift für Naturforschung B, 1987
3-5 On the basis of an improved synthesis of the 1,3,4,5,6-pentaacetate of myo-inositol, now available in only one step from that cyclitol in yields up to 90%, we prepared various derivatives of 1-deoxy-1-mercapto-scyllo-inositol (monothioscyllitol) via the mesylate 1 a or the trifluoromesylate 1 b , respectively.

Polarization and reprogramming of myeloid-derived suppressor cells [PDF]

Journal of Molecular Cell Biology, 2013
Myeloid-derived suppressor cells (MDSC) have recently emerged as one of the central regulators of the immune system. In recent years, interest in understanding MDSC biology and applying MDSC for therapeutic purpose has exploded exponentially. Despite recent progress in MDSC biology, the mechanisms underlying MDSC development from expansion and ...

Inequalities for the polar derivative and the generalized polar derivative of complex polynomials with restricted zeros

University of Aden Journal of Natural and Applied Sciences, 2023
     In this paper, certain new results concerning the maximum modulus of the polar derivative and the generalized polar derivative of a polynomial with restricted zeros are obtained. These estimates strengthen some well known inequalities for polynomial due to Tur n, Rather and Dar, Rather, Ali, Shafi and Dar  and others.

Sharp Estimation Type Inequalities for Lipschitzian Mappings in Euclidean Sense on a Disk

Journal of Function Spaces, 2021
Some sharp trapezoid and midpoint type inequalities for Lipschitzian bifunctions defined on a closed disk in Euclidean sense are obtained by the use of polar coordinates. Also, bifunctions whose partial derivative is Lipschitzian are considered.

Mitophagy of polarized sperm-derived mitochondria after fertilization

iScience, 2021
Loss of membrane potential of sperm mitochondria has been regarded as the first step preceding mitophagy degradation after their entry into the C. elegans oocyte at fertilization. This is in line with the classical view of mitophagy of defective or abnormal mitochondria and could serve as a recognition signal for their specific and quick autophagy ...

Some Bounds for the Polar Derivative of a Polynomial

International Journal of Mathematics and Mathematical Sciences, 2018
The polar derivative of a polynomial p(z) of degree n with respect to a complex number α is a polynomial np(z)+α-zp′(z), denoted by Dαp(z). Let 1≤R≤k. For a polynomial p(z) of degree n having all its zeros in z≤k, we investigate a lower bound of modulus ...

The polar and lateral flagella from Plesiomonas shigelloides are glycosylated with legionaminic acid

Frontiers in Microbiology, 2015
Plesiomonas shigelloides is the unique member of the Enterobacteriaceae family able to produce polar flagella when grow in liquid medium and lateral flagella when grown in solid or semisolid media. In this study on P. shigelloides 302-73 strain, we found
