Mitochondria‐Targeting Moieties Based on N‐Tethered Pyridinium Cations

Angewandte Chemie, EarlyView.
Pyridinium cations were benchmarked as mitochondria‐targeting moieties in a panel of N‐tethered fluorescent‐, bioactive‐, and inert‐cargo conjugates. 3,5‐Diphenylpyridinium (DPPy+) is a competent triphenylphosphonium (TPP+) surrogate, combining high mitochondria‐targeting efficiency with lower intrinsic effects on mitochondrial function.

On chromatic Zagreb indices of certain graphs [PDF]

Discrete Mathematics, Algorithms and Applications, 2017
Let [Formula: see text] be a finite and simple undirected connected graph of order [Formula: see text] and let [Formula: see text] be a proper vertex coloring of [Formula: see text]. Denote [Formula: see text] simply, [Formula: see text]. In this paper, we introduce a variation of the well-known Zagreb indices by utilizing the parameter [Formula: see ...

On the discrepancy between two Zagreb indices [PDF]

Discrete Mathematics, 2018
We examine the quantity \[S(G) = \sum_{uv\in E(G)} \min(\text{deg } u, \text{deg } v)\] over sets of graphs with a fixed number of edges. The main result shows the maximum possible value of $S(G)$ is achieved by three different classes of constructions, depending on the distance between the number of edges and the nearest triangular number. Furthermore

Bounds of Zagreb indices and hyper Zagreb indices

, 2016
The hyper Zagreb index is a kind of extensions of Zagreb index, used for predicting physicochemical properties of organic compounds. Given a graph $G= (V(G), E(G))$, the first hyper-Zagreb index is the sum of the square of edge degree over edge set $E(G)$ and defined as $HM_1(G)=\sum_{e=uv\in E(G)}d(e)^2$, where $d(e)=d(u)+d(v)$ is the edge degree.

GTI-space : the space of generalized topological indices

, 2008
A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way.

On Zagreb Indices as Complexity Indices

Croatica chemica acta, 2000
Two original Zagreb indices, denoted M1 and M2, and introduced in 1972, were symmetry-modified by summing up only degrees (SMM1) or edge-weights (SMM2) of symmetry nonequivalent vertices or edges of graphs. Their dependence on the structural features and symmetry of molecular graphs is studied. They were also compared to eight other complexity indices (

On a Linear Combination of Zagreb Indices

Discrete Mathematics Letters, 2023
Summary: The modified first Zagreb connection index of a triangle-free and quadrangle-free graph \(G\) is equal to \(2M_2(G)-M_1(G)\), where \(M_2(G)\) and \(M_1(G)\) are the well-known second and first Zagreb indices of \(G\), respectively. This paper involves the study of the linear combination \(2M_2(G)-M_1(G)\) of \(M_2(G)\) and \(M_1(G)\) when \(G\

Capacitive versus Faradaic Microelectrodes for Extracellular Stimulation: A Fully Coupled FEM–Hodgkin–Huxley Study of Thresholds and Current Redistribution

Advanced Electronic Materials, EarlyView.
A fully coupled FEM–HH model shows that ideally capacitive microelectrodes can achieve lower charge‐density thresholds than Faradaic contacts under current‐controlled stimulation. The advantage stems from the dynamics of surface current density on capacitive interfaces, which redirects current beneath adherent neurons.

Fuzzy Zagreb Indices and Some Bounds for Fuzzy Zagreb Energy

, 2021
Topological indices M1/M2 known as first/second Zagreb indices are defined as the sum of the sum/product of degrees of pairs of adjacent vertices of a simple graph.

Trends in 25 years of antihypertensive agent utilization in Croatia – an alert for scientific community and healthcare providers

British Journal of Clinical Pharmacology, EarlyView.
Aims Hypertension is a leading modifiable risk factor for cardiovascular mortality worldwide. This study aimed to evaluate 25‐year trends in antihypertensive agent (AHA) utilization in Croatia between 2000 and 2024. Methods We conducted a national, population‐based analysis using IMS and IQVIA pharmaceutical databases.
