Vertex Hyper-Zagreb Index of Graphs

open access: yesInternational Journal of Engineering & Technology, 2018
In this paper, we obtain the vertex hyper-Zagreb index for some composite graphs. Using the results obtained here, the vertex hyper-Zagreb index for some important classes of graphs are obtained.

Cost‐utility analysis of nusinersen–risdiplam switch in patients with spinal muscular atrophy in Croatia: A discrete event simulation model

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Introduction In recent years, the treatment of spinal muscular atrophy (SMA), a rare disease, has significantly progressed, improving patients' survival and overall quality of life. However, current SMA treatments are expensive, and some (nusinersen) are very inconvenient for patients.

First reformulated Zagreb indices of some classes of graphs

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
A topological index of a graph is a parameter related to the graph; it does not depend on labeling or pictorial representation of the graph. Graph operations plays a vital role to analyze the structure and properties of a large graph which is derived ...

The evolving therapeutic landscape of spinal muscular atrophy – A scoping review of investigational agents, emerging delivery technologies and strategic innovations

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Spinal muscular atrophy (SMA) is a severe neuromuscular disease with emerging therapeutic complexity. This review aims to systematically map the global pipeline of investigational treatments for SMA. Using ClinicalTrials.gov and complementary international registries, we identified 21 planned or ongoing interventional trials from 2020 to 2025 targeting

Plant diversity estimates of Mediterranean islands differ among biodiversity databases

open access: yesEcography, EarlyView.
Large‐scale biodiversity databases encompass three main types of data for plants, namely single species point occurrences, co‐occurrences in vegetation plots, and checklists for specific areas. Evidence shows that such data types exhibit specific biases, reporting different species assemblages at local scales.

Entropy measures of dendrimers using degree based indices

open access: yesSouth African Journal of Chemical Engineering
Topological indices play a crucial role as molecular descriptors in QSAR/QSPR research. Graph entropy measurements are of great importance in various fields like chemistry, discrete mathematics, and biology.

Some Upper Bounds on the First General Zagreb Index

open access: yesJournal of Mathematics, 2022
The first general Zagreb index MγG or zeroth-order general Randić index of a graph G is defined as MγG=∑v∈Vdvγ where γ is any nonzero real number, dv is the degree of the vertex v and γ=2 gives the classical first Zagreb index.

Probabilistic analysis of the First Zagreb index

open access: yesTransactions on Combinatorics, 2013
In this paper we study the Zagreb index in bucket recursive trees containing buckets with variable capacities. This model was introduced by Kazemi in 2012. Weobtain the mean and variance of the Zagreb index andintroduce a martingale based on this quantity.

Factors related to loss to follow‐up and low compliance in Helicobacter pylori‐infected children: The EuroPedHp Registry

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Factors related to loss to follow‐up and low compliance in Helicobacter pylori‐infected children. Abstract Objectives Monitoring for Helicobacter pylori (H. pylori)‐eradication is important, since symptom improvement does not indicate treatment success. Using EuroPedHp Registry data, we investigated characteristics of children missing monitoring visits
