Cholinergic inputs to motoneurons in the spinal cord augment focal muscle spasticity in rodents
British Journal of Pharmacology, EarlyView.Background and Purpose Cholinergic premotor inputs to motoneurons support high levels of motor output when required. However, the possible role of these inputs in pathologically elevated muscle tone has not been characterised. To address this, we examined the modulatory effect of spinal acetylcholine (ACh) on experimental spastic paralysis ...

Zagreb Connection Indices of Molecular Graphs Based on Operations
Complexity, 2020 Topological index (numeric number) is a mathematical coding of the molecular graphs that predicts the physicochemical, biological, toxicological, and structural properties of the chemical compounds that are directly associated with the molecular graphs ...

Cladistics, EarlyView.Abstract Subterranean ecosystems harbour exceptional biodiversity shaped by adaptation to extreme environments, yet remain poorly explored. Cave organisms, restricted to small, isolated populations, are extinction‐prone, making integrative species delimitation essential for biodiversity assessment and conservation.

Inverse problem for Zagreb indices
, 2018 The inverse problem for integer-valued topological indices is about the existence of a graph having its index value equal to a given integer. We solve this problem for the first and second Zagreb indices, and present analogous results also for the ...

Computing Topological Indices and Polynomials of the Rhenium Trioxide
Journal of Mathematics, 2022 In the study of mathematical chemistry and chemical graph theory, a topological index, also known as a connectivity index, is the arithmetical framework of a graph that specifies its topology and also graph invariant.

Computation of Zagreb indices and Zagreb polynomials of Sierpinski graphs
Hacettepe Journal of Mathematics and Statistics, 2020 The Sierpinski fractal or Sierpinski gasket and generalized Sierpinski graphs are objects of great interest in dynamical systems and probability. In this paper, we consider the Sierpinski gasket graph $S_{n}$, the generalized Sierpinski graphs $S(n,C_{3})$ and $S(n,C_{4})$.

Insect Conservation and Diversity, EarlyView.Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.

Some properties of the Zagreb eccentricity indices
Ars Mathematica Contemporanea, 2012 The concept of Zagreb eccentricity (E1 and E2) indices was introduced in the chemical graph theory very recently.In this paper we give some lower and upper bounds on the first Zagreb eccentricity and the second Zagreb eccentricity indices of trees and graphs, and also characterize the extremal graphs.
