Luke Howard, F.R.S., is an outstanding figure in the history of meteorology (1). His published works, notably The Climate of London (1818) based on his observations, were landmarks in the early history of the subject, while his theories of the causes of rain and the influence of atmospheric electricity on precipitation have been largely confirmed by modern investigation. His most significant contribution to the science, however, was the publication, in 1803, in his ‘Essay on the Modification of Clouds’ (5), of the first classification of the cloud formations on a scientific basis which found general acceptance: his Latin terminology—cirrus, cumulus, stratus and their modifications, including nimbus, the rain-cloud—is still employed in the modern classification of cloud forms (2).

AbstractGlioblastoma multiforme(GBM) is a grade IV WHO malignant tumor with astrocytic differentiation. As one of the most common clinically diagnosed central nervous system (CNS) oncological entries, there have been a wide variety of historical reports of the description and evolution of ideas regarding these tumors.The first recorded reports of gliomas were given in British scientific reports, by Berns in 1800 and in 1804 by Abernety, with the first comprehensive histomorphological description being given in 1865 by Rudolf Virchow. In 1926 Percival Bailey and Harvey Cushing gave the base for the modern classification of gliomas. Between 1934 and 1941 the most prolific researcher in glioma research was Hans-Joachim Scherer, who postulated some of the clinico-morphological aspects of GBM. With the introduction of molecular and genetic tests the true multifomity of GBM has been established, with different genotypes bearing the same histomorphological and IHC picture, as well as some of the aspects of gliomagenesis. For a GBM to develop, a specific trigger mutation needs to occur in a GBM stem cell – primary GBM, or a slow aggregation of individual mutations, without a distinct trigger mutation – secondary GBM.Knowledge of GBM has been closely related to general medical knowledge of the CNS since these malignancies were first described more than 200 years ago. Several great leaps have been made in that time, in the footsteps of both CNS and advancements in general medical knowledge.

Background: Traditional Persian Medicine (TPM) has a history of almost 10,000 years with practice and experience aspects. The existing information and experiences of physicians such as Avicenna clearly show the vast amount of knowledge in the classification and treatment of pathogenic worms. The aim of this paper was the description of the various types of helminths along with their treatment in medieval Persia and comparing them with new medical findings. Materials and Methods: We searched main Traditional Persian Medical and pharmacological texts about etiology, manifestation, diagnosis and treatment of worms in the human digestive system and the out come was compared with the data extracted from modern medical sources. A list of medicinal plants was also extracted from traditional pharmacological books and the anthelmintic properties of these plants were checked in Google Scholar, Scopus, PubMed and Ulrich's databases. Results: The results show the existence of theories on pathogenicity, physiopathology, symptoms and the classification of worms in TPM. TPM philosophers have divided worms into four groups and there is not great difference between old Persian and Modern classification. The old Persian scholars have explained a treatment procedure using a list of 48 medicinal plants and the anthelmintic effect of 23 plants have been shown in modern medicine studies. Conclusion: This study shows a more in-depth and thorough classification of pathogenic worms, their pathogenicity, symptoms and treatments in Traditional Persian Medical compared to Greek Medicine so that old Persian classification may be the base of modern taxonomy. More clinical trials are suggested for the efficacy and safety of these plants.

Introduction. The article provides an overview of research regarding word building in the Mordovian languages. The purpose of the study is to highlight the history of the study of word building in the Mordovian languages, and to analyze the works of D. V. Tsygankin, who made a significant contribution to the study of Mordovian derivatology, to the formation of the principles of its teaching and analysis. Materials and Methods. The material of the research is based on word building in the Mordovian languages. The work was performed using descriptive, comparative and historical-typological methods. Results and Discussion. Word building is considered a new research area. In Russia its formation is associated with the name of M. V. Lomonosov. In the design of word building as a academic branch in the 19th century the main role belongs to representatives of four scientific schools in Russia: in Moscow, Kharkov, Kazan and Petersburg. Word building has been considered as an independent object of study only since the mid–1940s, and since the late 1960s as a separate linguistic discipline. This progress became possible primarily thanks to the works by V. V. Vinogradov. A special role in the study of derivational processes in the Mordovian languages belongs to D. V. Tsygankin. The scholar described word formation as a system, defined basic concepts, characterized the methods of word formation, identified productive models, traced changes in word-building morphonology, developed the principles of studying word formation in higher education. Conclusion. A fairly large amount of material has been accumulated on the organization of the word-building system in the Mordovian languages. The number of works in the field of word building continues to grow, but not all of its problems have been resolved. For example, there is a need to develop a new classification of word building methods based on emerging data about the language.

Based on the analysis of literature sources, modern data are presented on the nosological structure of urachus diseases in adults and children, diagnostic methods, as well as treatment tactics for various anatomical variants of anomalies in the development of the urinary duct. A modern classification of urachal malformations caused by disorders of its obliteration is presented. Various modifications of the laparoscopic approach are considered for the most common types of this pathology. The reasons for the development of malignant neoplasms from the urachus tissue, including in the gender aspect, are described, and a comparative assessment of the methods of surgical treatment of urachus tumors is given.
