New Hopes in Cancer Battle - A Review of New Molecules and Treatment Strategies

Abstract: Background: Cancer is one of the most serious illnesses of our civilization. Therefore, scientists of different disciplines try to find new treatment strategies and new chemical molecules which might be useful in a cancer treatment. Objective: The goal of this work is to perform the most significant achievements in the area of chemotherapeutic treatment, published during the last two years. Methods: We reviewed almost 80 contributions, searching for new molecules with anticancer activity and treatment strategies. Results: We have presented tens of new anticancer molecules interacting with DNA or affecting cell cycle and new findings in this area. These compounds are chemically synthesized as well as are isolated from natural sources. The discovered molecules may induce cancer cells apoptosis, improve other cancer treatments, such as radiotherapy or reduce side effects of chemotherapy. Conclusion: The review shows that the cancer battle is still in progress and the combined studies in different disciplines, devoted to this subject, are a rapidly expanding area.

Revision of an extraordinary Selizini genus Urana Melichar, 1902 from Madagascar (Hemiptera: Fulgoromorpha: Flatidae)

Abstract: This paper revises an extraordinary Madagascan genus Urana Melichar, 1902, with two species Urana paradoxa Melichar, 1902 and Urana unica sp. nov. The genus represents the tribe Selizini of the subfamily Flatinae. Additionally, distribution of the genus is discussed.

Time-Fractional Diffusion with Mass Absorption in a Half-Line Domain due to Boundary Value of Concentration Varying Harmonically in Time.

Abstract: The time-fractional diffusion equation with mass absorption is studied in a half-line domain under the Dirichlet boundary condition varying harmonically in time. The Caputo derivative is employed. The solution is obtained using the Laplace transform with respect to time and the sin-Fourier transform with respect to the spatial coordinate. The results of numerical calculations are illustrated graphically.

Madagascar Flatidae (Hemiptera, Fulgoromorpha): state-of-the-art and research challenges

Abstract: The paper provides a historical review of the research on Flatidae in Madagascar and indicates future prospects. While the first two species of Madagascar Flatidae were described by Guerin-Meneville (1844), it was Signoret (1860) who made the first real attempt to enhance our knowledge of the Hemiptera fauna of Madagascar by describing several additional species. Over the following century and a half, several investigators have turned their attention to this group of insects, with the final number of species recorded for the island reaching 79. Despite this long history of research, it is evident that much still remains to be done. Detailed taxonomic research will allow the natural history of Madagascar and changes in the biological diversity of its endemic ecosystems to be better understood. This paper should be considered as an introduction to a complex study on the systematics and phylogeny of worldwide Flatidae planthoppers.
