CYLINDERS IN DEL PEZZO SURFACES WITH DU VAL SINGULARITIES
Belousov, Grigory Korean Mathematical Society 2017 대한수학회보 Vol.54 No.5
We consider del Pezzo surfaces with du Val singularities. We'll prove that a del Pezzo surface X with du Val singularities has a $-K_X-polar$ cylinder if and only if there exist tiger such that the support of this tiger does not contain anti-canonical divisor. Also we classify all del Pezzo surfaces X such that X has not any cylinders.

Unraveling the Biological Roles of Reactive Oxygen Species
Murphy, Michael P.,Holmgren, A.,Larsson, N.G.,Halliwell, B.,Chang, Christopher J.,Kalyanaraman, B.,Rhee, S.,Thornalley, Paul J.,Partridge, L.,Gems, D.,Nystrom, T.,Belousov, V.,Schumacker, Paul T.,Wint Cell Press 2011 Cell metabolism Vol.13 No.4
Reactive oxygen species are not only harmful agents that cause oxidative damage in pathologies, they also have important roles as regulatory agents in a range of biological phenomena. The relatively recent development of this more nuanced view presents a challenge to the biomedical research community on how best to assess the significance of reactive oxygen species and oxidative damage in biological systems. Considerable progress is being made in addressing these issues, and here we survey some recent developments for those contemplating research in this area.
Phytochemistry, ethnopharmacology and pharmacology of the genus Empetrum: a review

The genus Empetrum (family: Empetraceae) represents an abundant source of biologically active compounds with wide range of pharmacological effects. Empetrum species are widespread throughout the Northern hemisphere and extensively used in traditional medicine. Although biological effects of these plants have been studying for decades, recent analytical methods along with in vivo experiments provide new data on chemical compounds extracted from the species and their biological activities. This review focuses on phytochemistry, pharmacology and known biological effects of chemical compounds extracted from genus Empetrum to explore their therapeutic potential, particularly in seizure and other neurological disorders and includes an overview of scientific literature concerning the genus Empetrum published between 1987 and 2021.
