Vertex Hyper-Zagreb Index of Graphs
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. Â

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
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 ...

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
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.

Some Upper Bounds on the First General Zagreb Index
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
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. 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
