Calixarene-based langmuir monolayers : from crystallization templates to metal organic networks [PDF]

open access: yes, 2015
Molecular self-assembly plays a pivotal role in biological processes and living organisms can be considered as the result of the self-assembly of discrete molecular building blocks into sophisticated functional structures.

A new megastigmane, known porphyrinic and galloylated bioactive derivatives from the leaves of

open access: yesJournal of Chemical Research, 2022
Investigation of the non-polar (rich in chlorophyll) and polar fractions of the ethyl acetate extract of Gymnosporia senegalensis (Lam.) Loes. leaves led to the isolation of nine compounds, including one new megastigmane derivative, (3 R* ,5 S* ,6 R* ,7 ...

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

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

open access: yesFrontiers 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

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

open access: yesJournal 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.

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

PRINCIPAL COMPONENT ANALYSIS OF DIPOLE-MOMENT DERIVATIVE SIGNS OF CHLOROFORM [PDF]

open access: yes, 2015
The use of principal components as a basis for a graphical procedure to analyze polar tensor data is proposed. Molecular orbital and experimental polar tensor data for all possible sign combinations of the partial derivative p/partial derivative Q(j) of ...

Refinements of inequalities on extremal problems of polynomials

open access: yesOpen Mathematics
Let H(z) be a polynomial of degree n, and for any complex number α, let D α H(z) = nH(z) + (α − z)H′(z) denote the polar derivative of H(z) with respect to α.

Synthesis of purines and adenines containing the hexafluoroisopropyl group

open access: yesBeilstein Journal of Organic Chemistry, 2020
Several new derivatives of adenine, purine, and theophylline containing the (CF3)2CH group connected to a nitrogen atom of the imidazole ring were prepared by the reaction of 2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithietane (1) with the corresponding ...
