European Association for the Study of the Liver Hepatocellular Carcinoma summit 2014: old questions, new (or few) answers?

2014

, the European Association for the Study of the Liver (EASL) organized the 2014 EASL HCC Summit in Geneva, Switzerland from 13 to 16 February 2014. A number of interesting issues on the management of hepatocellular carci-noma (HCC) have been addressed during this meeting. However, our feeling is that only few answers have been given to those questions, mainly because of the still poor knowledge of the molecular basis and the natural history of HCC.HCC is a complex disease, associated in the wide majority of cases with under -lying cirrhosis. In addition, HCC pre-sents with high heterogeneity

Update on new approaches in the management of hepatocellular carcinoma

2010

Abstract: Hepatocellular carcinoma (HCC) is a major health problem. It is currently the third cause of cancer-related death, it is highly prevalent in the Asia–Pacific region and Africa, and is increasing in Western countries. The natural history of HCC is very heterogeneous and prediction of survival in individual patients is not satisfactory because of the wide spectrum of the disease. During the past decade, major advances have been achieved in prevention, through better surveillance of patients at risk, and in therapy through better surgical and ablative therapies and multimodal treatment approaches. Moreover, the increasing knowledge of molecular hepatocarcinogenesis provides the oppor…

Bild unserer irren Anwesenheit/auf der Oberfläche der Erde. L’immagine come storia naturale del presente nella poetica diW. G. Sebald

2017

The poem Nach der Natur by W. G. Sebald, real germinal place of its author’s subsequent literary production, is a salient moment of confrontation for today's philosophical gaze; our historical time and our own humanity are configured as “natural history” (Benjamin), in a compositional game in which the present time acquires the character of a timeless distance projecting it on the background of a mournful nature, entrusting to the roughness of the poetic material and to its conceptual weaving the task of an unprecedented presentification of some layers of reality of rare density.

Claves para entender los efectos de la crisis económica actual en el modelo turístico valenciano

2016

El turismo en la Comunidad Valenciana es una actividad económica de carácter estructural. Una de las características más evidentes del desarrollo turístico valenciano es su polarización espacial, con una elevada concentración del crecimiento en el litoral, a ello se une su carácter estacional, lo que junto con la primacía de la oferta extrahotelera, constituye la característica diferenciadora del turismo valenciano. Desde 2009, el análisis de la información estadística oficial nos muestra unas ligeras modificaciones en la demanda con claro impacto sobre la oferta (reducción del gasto por turista, aumento de las estancias de fines de semana, reducción de la estancia media, aumento del turism…

Zoological Checklists: From Natural History Museums to Ecosystems

2023

Backwards and forwards at once, the zoological checklists bring the past into the present and draw a direction towards the future. They cover historical and current information providing open data for environmental issues. The present-day research framework aims to produce papers reporting lists of animal species, after a couple of decades of absolute refusal of such inventories, years where the prevalence of studies has been focused on ecological or molecular statistics. Now, the contemporary era is moving towards the gathering of organized data, shared on web platforms, and cross-linked in a sort of global metadata outcome. It means that a single record of the occurrence of a species can …

Richard Bradley - étude de quelques illustrations pré-évolutionnistes

2015

Richard Bradley (1688-1732) is an English botanist more particularly known for his books on gardening and exotic plants. He published in 1721 a treatise entitled A Philosophical Account of the Works of Nature, in which he offers the reader a complete and systematic description of the natural world organized in the best way by a benevolent God according to the principle of the Great Chain of Being. He discovers plenty of evidence of a divine order via the use of the microscope and the recent discoveries on plant sexual reproduction. However, a study of some of the illustrations reveals some doubts about the Great Chain of Being, notably regarding the place of man within nature.

Critical limb ischaemia: definition and natural hystory

2004

The term critical limb ischemia refers to a condition characterized by chronic ischemic at-rest pain, ulcers, or gangrene in one or both legs attributable to objectively proven arterial occlusive disease. Critical limb ischemia implies chronicity and is to be distinguished from acute limb ischemia. Its incidence is approximately 500 to 1000 per million year, with the highest rates among older subjects, smokers and diabetics. The rate of primary amputation ranges from 10% to 40%, and was performed only when no graftable distal vessels were present, or in neurologically impaired or hopelessly nonambulatory patients. Contrarily, in some highly specialized and aggressive centres about 90% of pa…

Motyw "wieśnej rycerki", czyli światowe sprawy pani wrony w twórczości Mikołaja Reja

2020

The subject of the article is the symbolism of the crow considered against the background of the old encyclopedic tradition. The comparison of erudite content in the field of natural history with fragments of Mikołaj Rej’s works brings interesting insights. It turns out that the crow occupies a prominent place in the allegorical zoo of Reja. Allegoric interpretations related to the theme of this bird in Nagłowiczanin’s works do not go beyond the traditionally accepted interpretations. Unpleasant croaking, raven exterior, or even the crow’s thieving habits did not deprive her of universal friendliness. Already in Aesop’s fairy tales you can admire the extraordinary cunning and thrift of this…
