A majorization method for localizing graph topological indices

, 2011
This paper presents a unified approach for localizing some relevant graph topological indices via majorization techniques. Through this method, old and new bounds are derived and numerical examples are provided, showing how former results in the ...

CSF‐Compartmentalized Antibody Glycoprofiles in NMDAR Encephalitis Associate with Etiology and Functional Recovery

Annals of Neurology, EarlyView.
Objective To characterize Fc‐glycosylation profiles in patients with anti‐N‐methyl‐D‐aspartate receptor encephalitis (NMDARe) and assess their association with antibody compartmentalization (cerebrospinal fluid [CSF] vs serum), disease triggers (viral, tumor‐related or idiopathic), and 1‐year outcomes.

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.

On Zagreb Eccentricity Indices

Croatica Chemica Acta, 2011
Zagreb eccentricity indices were proposed analogously to Zagreb indices already known and used for almost forty years. For a connected graph, the first Zagreb eccentricity index is defined as the sum of the squares of the eccentricities of the vertices, and the second Zagreb eccentricity index is defined as the sum of the products of the eccentricities

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

British 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
