The Poincaré–Birkhoff Theorem for a Class of Degenerate Planar Hamiltonian Systems

Advanced Nonlinear Studies, 2021
In this paper, we investigate the problem of the existence and multiplicity of periodic solutions to the planar Hamiltonian system x′=-λ⁢α⁢(t)⁢f⁢(y)x^{\prime}=-\lambda\alpha(t)f(y), y′=λ⁢β⁢(t)⁢g⁢(x)y^{\prime}=\lambda\beta(t)g(x), where α,β\alpha,\beta ...

Topical treatment of equine sarcoids with imiquimod 5% cream or Sanguinaria canadensis and zinc chloride – an open prospective study

Veterinary Dermatology, Volume 31, Issue 6, Page 471-e126, December 2020., 2020
Background – Equine sarcoids are the most prevalent skin neoplasm in horses worldwide. Although several treatments are available, none are consistently effective and recurrence is common. Objectives – To evaluate the efficacy and safety of topical imiquimod 5% cream and Sanguinaria canadensis + zinc chloride for treatment of equine sarcoids and ...
