What it Means to be a Stranger to Oneself
2009
In adult education there is always a problem of prefabricated and in many respect fixed opinions and views of the world. In this sense, I will argue, that the starting point of radical education should be in the destruction of these walls of belief that people build around themselves in order to feel safe. In this connection I will talk about ‘gentle shattering of identities’ as a problem and a method of radical education. When we as adult educators are trying to gently shatter these solidified identities and pre‐packed ways of being and acting in the world, we are moving in the field of questions that Sigmund Freud tackled with the concepts of ‘de‐personalization’ and ‘de‐realization’. The…
La utilización de la historia de las ciencias en la enseñanza de la física y la química
1996
Most recently we have assisted to a considerable increase of investigations on cons tructivi Stic approaches to Science teaching, but among all these works we rarely found detailed proposals for including the History and Philosophy of Science. In this paper we consider how to initiate this trend and which should be the aims in order to get a better Science teaching. We consider basically which the pupils’ perceptions of Science in a High School level are in order to show how we can modify them by means of introducing the History of Science under a new perspective.
El Instituto Médico Valenciano y la difusión de la vacuna
2004
The Medical Valencian Institute promoted a campaign of smallpox free vaccination (1851- 1894) by means of humanized vaccine sent from England. It spread the vaccination for the whole Spain and published careful statistics of the vaccinations practised in the Bulletin of the Medical Valencian Institute. The National Institute of Vaccination (1871) did not recognize his labor and one denied to him the category of Provincial Institute of Vaccination.
Embryo effects in human implantation: embryonic regulation of endometrial molecules in human implantation.
2001
: Embryonic implantation requires coordinated development of the blastocyst and the maternal endometrium. Considerable advances have been made in the understanding of the cell biology of human embryo and maternal endometrium as separate entities. Nevertheless, communication between them and their reciprocal effects on each other constitute an exciting and as-yet unsolved problem in reproductive medicine. Cross-talk among the embryo, endometrium, and the corpus luteum are known to occur in ruminants and primates; more specifically, endometrial-embryonic interactions have been reported in rodents and primates. Here, we present updated information in humans on the embryonic regulation of endom…
El papel desempeñado por los programas país de la Organización Mundial de la Salud en el desarrollo de la virología en España, 1951-1975
2020
Abstract Within the framework of recent historiography about the role of the World Health Organization (WHO) in modernizing public health and the multifaceted concept of global health, this study addresses the impact of the WHO’s “country programs” in Spain from the time it was admitted to this organization in 1951 to 1975. This research adopts a transnational historical perspective and emphasizes attention to the circulation of health knowledge, practices, and people, and focuses on the Spain-0001 and Spain-0025programs, their role in the development of virology in Spain, and the transformation of public health. Sources include historical archives (WHO, the Spanish National Health School),…
Aromatase and amphiregulin are correspondingly expressed in human liver cancer cells
2009
Human hepatocellular carcinoma (HCC) is associated with high mortality rates, being the third most common cause of cancer death worldwide. Although estrogens have been implicated in HCC, their potential role in development and/or progression of this malignancy remains unclear. In this study we investigated mRNA and protein expression of aromatase (Aro) and amphiregulin (AREG) in relation to estrogen receptors (ERs), in HepG2, Huh7, and HA22T human malignant liver cell lines, using RT-PCR and Western blot analyses. Aro expression was significantly higher (approximately 13-fold, P= 0.003) in HepG2 cells than in Huh7 cells, while no Aro expression could be detected in HA22T cells. Interestingl…
An ?-Adrenoceptor Facilitating the Stimulation-Evoked Acetylcholine Release in the Rat Perfused Heart

Epidemiological and virological studies into the poliomyelitis in Valencia (1959-1969)
2009
Studies into the polio virus began in Valencia in 1959 with the work undertaken by the microbiologist Vicente Sanchis-Bayarri Vaillant. After his education at the Rochester University and at the Pasteur Institute, Sanchis-Bayarri Vaillant established a laboratory of cell cultures at the Faculty of Medicine in Valencia, where he developed a new diagnostic technique for the poliomyelitis virus. In addition, epidemiological studies were carried out both prior to and post the 1963 vaccination campaign, which proved that Sabin’s oral vaccine was both effective and safe for use.
Current Surgical Treatment Standards for Esophageal and Esophagogastric Junction Cancer
2020
A number of different surgical techniques for the treatment of cancer of the esophagus and the esophagogastric junction have been proposed. Guidelines generally recommend a transthoracic approach for esophageal cancer, including Siewert type I tumors. In tumors of the proximal esophageal third, transthoracic esophagectomy may be extended to a three-field approach, including resection of cervical lymph nodes. However, the choice between transthoracic esophagectomy with intrathoracic anastomosis (Ivor Lewis esophagectomy) and the three-incision approach with cervical esophago-gastrostomy (McKeown esophagectomy) remains controversial, with guidelines varying among different countries. Furtherm…
Surgical robotics for esophageal cancer
2018
We present an update on robotic techniques and their advantages and use in esophageal cancer surgery. Recent work has shown tremendous progress in robotic-assisted minimally invasive esophagectomy (RAMIE) and lymphadenectomy for esophageal cancer, as well as benefits of robotic surgery in high upper esophageal tumors and T4b disease. We discuss the different RAMIE techniques, especially for intrathoracic anastomosis. The ongoing ROBOT trial had demonstrated superiority of robotic esophageal cancer surgery over open esophagectomy. There are various putative technical advantages of RAMIE over minimally invasive esophagectomy, which need to be proven in future trials.
