Chemical Markers and Bioactivity of Algerian Royal Jelly: Influence of Bee Subspecies, Geography, and Lyophilization. [PDF]

Chem Biodivers
Algerian royal jelly from native honey bees shows chemical diversity influenced by geography and subspecies. Lyophilization preserves key compounds, including 10‐HDA and phenolics. Biological assays reveal modest antioxidant activity and selective cytotoxicity against Reh leukemia cells, while anti‐inflammatory effects are limited.

L∞-error estimates of a finite element method for Hamilton-Jacobi-Bellman equations with nonlinear source terms with mixed boundary condition

Demonstratio Mathematica, 2021
In this paper, we introduce a new method to analyze the convergence of the standard finite element method for Hamilton-Jacobi-Bellman equation with noncoercive operators with nonlinear source terms with the mixed boundary conditions.

The existence of periodic solutions for a second order nonlinear neutral differential equation with functional delay

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this article we study the existence of periodic solutions of the second order nonlinear neutral differential equation with functional delay \[ \frac{d^{2}}{dt^{2}}x\left( t\right) +p\left( t\right) \frac{d}{dt}x\left( t\right) +q\left( t\right)
