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).

Abstract The awareness of the widespread influence of hypertension on various organ systems is ever increasing. Changes associated with this disease can be observed in the heart, brain, kidneys, but also the organ of vision. These usual microvascular changes are defined as hypertensive retinopathy. During a funduscopic examination, abnormalities such as narrowing of arterioles, symptoms of arteriole and vein intersection, cotton wool spots, intra-retinal exudates, retinal haemorrhages, and in severe cases even swelling of the optic disc and macula. This review presents an overview of the changes at the fundus of the eye that may occur in patients with hypertension, as well as problems with the classification of hypertensive retinopathy over the years, and the development of diagnostic methods in ophthalmology and fundoscopic imaging.

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.

The term lepidic is used prominently in the recently published multidisciplinary classification of adenocarcinoma. The lack of use in common (nonmedical) English has led to some confusion over the proper definition of this term. This historical perspective traces the history of the term lepidic from its origins at McGill University in Montreal, Canada, through its uses in English pathologic descriptions, to its current state in pulmonary pathology.

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.

The genus Bolborhinum Boucomont (Coleoptera: Geotrupidae: Bolboceratinae: Bolboceratini) is revised and now contains eight species: B. geotrupoides (Laporte), B. laesicolle (Fairmaire), B. nasutum (Fairmaire and Germain), B. seai (Martínez), B. shajovskoyi (Martínez), B. tricorne (Solier), B. trilobulicorne new species, and B. tubericeps (Fairmaire). The genus Bolborhinum is redescribed and a key to species in English and Spanish, a checklist, distributional and temporal data, and designation of lectotypes and neotypes are given. All species in the genus are diagnosed and illustrated, and distributional records with maps for all species are included. Additionally, some observations on the natural history of Bolborhinum species are presented. One new synonym is proposed: Bolboceras binasutum Fairmaire and Germain is synonymized under Bolborhinum geotrupoides. Lectotypes are designated for the following species-group names: Bolboceras binasutum Fairmaire and Germain (a junior synonym of Bolborhinum geotrupoides), Bolboceras distinguendum Fairmaire and Germain (a junior synonym of Bolborhinum geotrupoides), Bolboceras laesicolle Fairmaire (now Bolborhinum laesicolle), Bolboceras nasutum Fairmaire and Germain (now Bolborhinum nasutum), Bolboceras tetraodon Redtenbacher (a junior synonym of Bolborhinum tubericeps), Bolboceras tricorne Solier (now Bolborhinum tricorne), and Bolboceras tubericeps Fairmaire (now Bolborhinum tubericeps). Neotypes are designated for the following species-group names: Bolboceras andicolaPhilippi (a junior synonym of Bolborhinum nasutum), Bolboceras bicorne Philippi (a junior synonym of Bolborhinum tubericeps), Bolboceras excavatum Philippi (a junior synonym of Bolborhinum laesicolle), and Bolboceras geotrupoides Laporte (now Bolborhinum geotrupoides). Additionally, we here elevate the subgenera Pereirabolbus Martínez and Zefevazia Martínez to the generic level based on morphological comparisons with the genus Bolborhinum. As a result, the following combinations reflect this change in status: Pereirabolbus castaneus (Klug), Pereirabolbus tucumanensis (Boucomont), Zefevazia cantisanii (Martínez), Zefevazia peruana (Boucomont), Zefevazia quinquedentata (Felsche), and Zefevazia rosascostai Martínez. These changes are congruent with the generic concepts of Bolboceratinae from other parts of the world, and with the modern classification of the group.El género Bolborhinum Boucomont (Coleoptera: Geotrupidae: Bolboceratinae: Bolboceratini) es revisado y ahora contiene ocho especies: B. geotrupoides (Laporte), B. laesicolle (Fairmaire), B. nasutum (Fairmaire y Germain), B. seai (Martínez), B. shajovskoyi (Martínez), B. tricorne (Solier), B. trilobulicorne nueva especie, y B. tubericeps (Fairmaire). El género Bolborhinum es redescrito, se presentan claves en inglés y español para la identificación de todas las especies, se proveen caracteres diagnósticos, descripciones e ilustraciones. Además se incluye un listado taxonómico, registros de distribución con mapas y se designan lectotipos y neotipos cuando corresponda. Adicionalmente algunas observaciones biológicas del género Bolborhinum son presentadas. Una nueva sinonimia es propuesta: Bolboceras binasutum Fairmaire y Germain es sinonimizado bajo Bolborhinum geotrupoides. Lectotipos son designados para los siguientes nombres: Bolboceras binasutum Fairmaire y Germain (sinónimo menor de Bolborhinum geotrupoides), Bolboceras distinguendum Fairmaire y Germain (sinónimo menor de Bolborhinum geotrupoides), Bolboceras laesicolle Fairmaire (ahora Bolborhinum laesicolle), Bolboceras nasutum Fairmaire y Germain (ahora Bolborhinum nasutum), Bolboceras tetraodon Redtenbacher (sinónimo menor de Bolborhinum tubericeps), Bolboceras tricorne Solier (ahora Bolborhinum tricorne), y Bolboceras tubericeps Fairmaire (ahora Bolborhinum tubericeps). Neotipos son designados para los siguientes nombres: Bolboceras andicola Philippi (sinónimo menor de Bolborhinum nasutum), Bolboceras bicorne Philippi (sinónimo menor Bolborhinum tubericeps), Bolboceras excavatum Philippi (sinónimo menor de Bolborhinum laesicolle), y Bolboceras geotrupoides Laporte (ahora Bolborhinum geotrupoides). Adicionalmente, nosotros elevamos los subgéneros Pereirabolbus Martínez y Zefevazia Martínez a nivel genérico basado en la comparación morfológica con el género Bolborhinum. Como resultado, los siguientes combinaciones reflejan este cambio de estatus: Pereirabolbus castaneus (Klug), Pereirabolbus tucumanensis (Boucomont), Zefevazia cantisanii (Martínez), Zefevazia peruana (Boucomont), Zefevazia quinquedentata (Felsche), y Zefevazia rosascostai Martínez. Estos cambios son congruentes con los conceptos genéricos de Bolboceratinae de otras partes del mundo, y con la clasificación moderna del grupo.
