Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Evaluation of Enzyme Inhibition and Kinetic Profiles of Origanum Essential Oils on Metabolic and Central Nervous System Targets

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
The essential oils of three Origanum species were chemically characterized and evaluated for their antioxidant and enzyme inhibitory activities. The different compositions confer selective bioactivities: O. vulgare exhibits good antioxidant and α‐glucosidase inhibitory activity, O. majorana shows promising tyrosinase inhibition, and O.

Variational Problems Involving a Caputo-Type Fractional Derivative [PDF]

open access: yesJournal of Optimization Theory and Applications, 2016
The aim of this paper is to study certain problems of calculus of variations, that are dependent upon a Lagrange function on a Caputo-type fractional derivative. This type of fractional operator is a generalization of the Caputo and the Caputo--Hadamard fractional derivatives, that are dependent on a real parameter ro.

A highly accurate method for multi-term time fractional diffusion equation in two dimensions with ψ-Caputo fractional derivative

open access: yesResults in Applied Mathematics
In this study, the ψ-Caputo fractional derivative (as a generalization of the classical Caputo derivative where the fractional derivative is defined with respect to the function ψ) is considered to introduce a class of multi-term time fractional 2D ...

Curcumin Nanoformulations for Dermatological Applications: From Nutraceuticals to Nanocarriers

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Nanotechnology‐based delivery platforms enhance the cutaneous administration of curcumin. Loading free curcumin into polymeric micelles, metal‐based nanoparticles, nanogels/hydrogels, liposomes, polymeric nanoparticles, or nanoemulsions/nanocrystals helps address its low solubility, poor stability and limited skin permeation. As a result, these systems

Unpacking the Impact of Nutri‐Score on Consumer Choices in Italy: Evidence From a Menu Planning Experiment

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Overnutrition represents a major public health issue, and front‐of‐pack labels like Nutri‐Score aim to promote healthier choices. This study shows that Nutri‐Score shifts consumer selections toward healthier options, especially at scale extremes. It also modifies meal composition by encouraging healthier pairings and category switching, particularly ...

Survey and new results on boundary-value problems of singular fractional differential equations with impulse effects

open access: yesElectronic Journal of Differential Equations, 2016
Firstly we prove existence and uniqueness of solutions of Cauchy problems of linear fractional differential equations (LFDEs) with two variable coefficients involving Caputo fractional derivative, Riemann-Liouville derivative, Caputo type Hadamard ...

Homotopy Perturbation ρ-Laplace Transform Method and Its Application to the Fractional Diffusion Equation and the Fractional Diffusion-Reaction Equation

open access: yesFractal and Fractional, 2019
In this paper, the approximate solutions of the fractional diffusion equations described by the fractional derivative operator were investigated. The homotopy perturbation Laplace transform method of getting the approximate solution was proposed.
