Environmental and seasonal filtering of taxonomic, functional and phylogenetic diversity patterns of mountain butterflies in a prime butterfly area, Greece

open access: yesInsect Conservation and Diversity, EarlyView.
Forest clearings support butterfly communities comparable to mountainous grasslands in alpha‐diversity and conservation value, yet remain compositionally distinct. Generalized linear models (GLMs) showed three key habitat predictors shaping multifaceted diversity and community composition: herb/grass height, flowerhead abundance and elevation.

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

open access: yesInsect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Management of Non‐Plaque‐Induced Gingival Conditions: A Systematic Review—Part 2: Inflammatory and Immune Conditions; Neoplasms; and Gingival Pigmentation

open access: yesJournal of Clinical Periodontology, EarlyView.
ABSTRACT Aims This systematic review assesses current evidence on the management of non‐plaque (dental biofilm)‐induced gingival diseases and conditions (NPIGDs), including (i) inflammatory and immune conditions, (ii) neoplasms and (iii) gingival pigmentations.

Computing Connection-Based Topological Indices of Sudoku Graphs

open access: yesJournal of Mathematics, 2022
A topological index (TI) is a function that associates a numeric number to the under-study molecular graph. The first TI based on distance was presented by Wiener to find the boiling point of paraffins.

European S2k guidelines for hidradenitis suppurativa/acne inversa Part 1. Epidemiology, diagnosis and clinical assessment

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
Updated S2k hidradenitis suppurativa (HS) guidelines provide expert consensus on diagnosis, assessment and comorbidities. Expanded substantially since the 2015 version, they reflect rapid growth in HS literature and aim to improve generalist‐level patient care through evidence‐informed, consensus‐based guidance.

The and -Analogs of Zagreb Indices and Coindices of Graphs [PDF]

open access: yes, 2012
The first and second Zagreb indices were first introduced by Gutman and Trinajstić (1972). It is reported that these indices are useful in the study of anti-inflammatory activities of certain chemical instances, and in elsewhere.

On Zagreb indices of graphs

open access: yes, 2023
Let ${\mathcal G}_n$ be the set of class of graphs of order $n$. The first Zagreb index $M_1(G)$ is equal to the sum of squares of the degrees of the vertices, and the second Zagreb index $M_2(G)$ is equal to the sum of the products of the degrees of pairs of adjacent vertices of the underlying molecular graph $G$.
