Modeling of the Acute Toxicity of Benzene Derivatives by Complementary QSAR Methods [PDF]

open access: yes, 2013
A data set containing acute toxicity values (96-h LC50) of 69 substituted benzenes for fathead minnow (Pimephales promelas) was investigated with two Quantitative Structure- Activity Relationship (QSAR) models, either using or not using molecular ...

Probiotics‐derived postbiotics improve host metabolic syndrome by activating the adipocyte thermogenic signaling pathway in high‐fat diet‐fed mice

open access: yesiMetaOmics, EarlyView.
This schematic illustrates how probiotics‐derived postbiotics (PLBK®1–5) combat high‐fat diet‐induced obesity. Postbiotics remodel gut microbiota, boosting beneficial metabolites. These metabolites activate adipocyte thermogenesis (Ucp1/AMPK pathway), resulting in reduced body weight, improved insulin sensitivity, and alleviated hepatic steatosis in ...

QSPR analiza polarografskih poluvalnih redukcijskih potencijala benzenoidnih ugljikovodika [PDF]

open access: yes, 2006
Correlation between the polarographic half-wave reduction potentials and the set of molecular descriptors of lower benzenoid hydrocarbons was made by the CROMRsel modeling procedure. The following descriptors were used in the modeling procedure: electron

Synthesis and Characterization of Juglone‐Derived cu (II), Mn (II) and Zn (II) Complexes and Investigation of Their Cytotoxic Activities Against Lung and Colon Cancer Cells in Vitro and in Silico

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Three new Zn (II), Cu (II) and Mn (II) complexes have been synthesized from 5‐hydroxy‐1,4‐naphthoquinone (HNQ). Elemental analysis, magnetic susceptibility, UV–Vis, IR and Mass spectrometry have all been used to explore the structural characterization of these compounds.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Computation of Topological Indices of Double and Strong Double Graphs of Circumcoronene Series of Benzenoid Hm

open access: yesJournal of Mathematics, 2022
Topological indices are very useful to assume certain physiochemical properties of the chemical compound. A molecular descriptor which changes the molecular structures into certain real numbers is said to be a topological index. In chemical graph theory,

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

open access: yesNordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Eccentric connectivity index [PDF]

open access: yes, 2010
The eccentric connectivity index $\xi^c$ is a novel distance--based molecular structure descriptor that was recently used for mathematical modeling of biological activities of diverse nature. It is defined as $\xi^c (G) = \sum_{v \in V (G)} deg (v) \cdot

Phytochemical analysis and anti-infective potential of fungal endophytes isolated from Nigella sativa seeds

open access: yesBMC Microbiology, 2023
Endophytic fungi, particularly from higher plants have proven to be a rich source of antimicrobial secondary metabolites. The purpose of this study is to examine the antimicrobial potential of three endophytic fungi Aspergillus sp.
