Transhepatic percutaneous endoscopic gastrostomy  [PDF]
Guido Poggi, Benedetta Montagna, Pamela Di Cesare
Open Journal of Gastroenterology (OJGas) , 2013, DOI: 10.4236/ojgas.2013.32014
Abstract:

We describe the case of a hepatic injury after the insertion of a PEG. In a cirrhotic woman affected by a locally advanced cancer of the pharynx, the PEG tube was inserted through the edge of the left lobe of the liver. The patient was treated with a conservative approach by managing abdominal pain and the PEG was removed after 4 months without complication. Hepatic injury is a rare complication of PEG placement; in order to avoid it, PEG tube should be inserted to the left of the abdominal midline and the lower edge of the liver should be defined by palpation; in cirrhotic patients, where left hepatic lobe hyper-trophy is common, ultrasound guidance could have been appropriate.

Multimodality treatment of unresectable hepatic metastases from pancreatic glucagonoma

Rare Tumors , 2009, DOI: 10.4081/rt.2009.e6
Abstract: Glucagonomas are pancreatic islet cell tumors arising from the alpha cells which belong to neuroendocrine tumors. They frequently metastasize to the liver. We report the case of a 52- year old man with a pancreatic glucagonoma with synchronous multiple liver metastases treated by surgery, transarterial chemoembolization, percutaneous radiofrequency thermal ablation and long-acting octreotide. Our report confirms that a multimodal approach is very effective in patients with unresectable liver metastases from pancreatic endocrine tumors providing long-lasting palliation and probably prolonging survival.

Abstract: The currently recommended treatment for patients infected with hepatitis C virus (HCV) is pegilated interferon α (IFN α) plus ribavirin. Despite the numerous benefits of this therapy, there is an increasing concern regarding his tolerance. Among the most common side effects, interferon may trigger the onset or exacerbation of autoimmune diseases. When chronic hepatitis C coexists with an autoimmune disorder, it is not clear whether using interferon is better than avoiding it. We evaluated the disease state of a 55-year old female affected by sistemic sclerosis (SSc), during and after therapy with IFNα pegilated plus ribavirin for chronic HCV infection. We were worried about the potential worsening of the autoimmune disease during the therapy, but we were confident that we would give our patient a short course of peginterferon and ribavirin. A mild, asymptomatic worsening of lung SSc was observed during IFN administration, without life threatening symptoms. After 24 months follow up we observed the maintenance of the virological response and a good control of the rheumatological disease. Thus, in liver disease at high risk of progression and concomitant SSc, the antiviral therapy with IFNα is a feasible approach.
Accelerated Repair and Reduced Mutagenicity of DNA Damage Induced by Cigarette Smoke in Human Bronchial Cells Transfected with E.coli Formamidopyrimidine DNA Glycosylase

Abstract: Cigarette smoke (CS) is associated to a number of pathologies including lung cancer. Its mutagenic and carcinogenic effects are partially linked to the presence of reactive oxygen species and polycyclic aromatic hydrocarbons (PAH) inducing DNA damage. The bacterial DNA repair enzyme formamidopyrimidine DNA glycosylase (FPG) repairs both oxidized bases and different types of bulky DNA adducts. We investigated in vitro whether FPG expression may enhance DNA repair of CS-damaged DNA and counteract the mutagenic effects of CS in human lung cells. NCI-H727 non small cell lung carcinoma cells were transfected with a plasmid vector expressing FPG fused to the Enhanced Green Fluorescent Protein (EGFP). Cells expressing the fusion protein EGFP-FPG displayed accelerated repair of adducts and DNA breaks induced by CS condensate. The mutant frequencies induced by low concentrations of CS condensate to the Na+K+-ATPase locus (ouar) were significantly reduced in cells expressing EGFP-FPG. Hence, expression of the bacterial DNA repair protein FPG stably protects human lung cells from the mutagenic effects of CS by improving cells’ capacity to repair damaged DNA.
Estrategias discursivas y representaciones del Proyecto de Ley Agraria (1974) en el periódico La Tierra
Poggi, Marina;
Intercom: Revista Brasileira de Ciências da Comunica??o , 2011, DOI: 10.1590/S1809-58442011000100004
Abstract: in june of 1974, the argentine ministry of economy elaborates and he puts in study the project of agrarian law, in order to regulate the use, dominion and possession of the earth, using the fundament that the earth should have a social function. the plaintext of the project is published in june of 1974 by the newspaper la nación; quickly the news acquires relevance and reproduces in the national press, bringing about adverse reactions as much as favorable in different agrarian organizations.the intention of this study is to analyze the argumentative schemes used by la tierra newspaper of the faa, to construct a discourse in favor of the project and to use it as tool of fight for the modification of the system of possession of the earth. the format of weekly information of the newspaper makes possible to settle in an intermediate position between the average daily graphs of traffic and the magazine, which allows him to become a specialized and simultaneously reflective source of intelligence. as methodologic tools are used some propose categories by the critical analysis of the discourse.
Il cervello e la psicologia romantica
Poggi, Stefano;
Trans/Form/A??o , 2000, DOI: 10.1590/S0101-31732000000100006
Abstract: the subject is a historical investigation of german neurology from the first decades of the nineteen century, represented by burdach and carus, and its relation to the romantic presuppositions of the biological approach. carus accentuates the necessity of an anatomical research of the brain and considers a total organism, attesting the influence of schelling's philosophy. burdach, for his part, investigates the cerebral structure in conexion with sensibility and with the evolutionary process.

Does Gravitation Have an Influence on Electromagnetism?  [PDF]
Guido Zbiral
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.329158
Abstract: For many years physicists have been engaged on research around the globe in fields such as the unification of gravita- tion and electromagnetism, and an explanation for dark matter and dark energy, etc., but so far to little avail. One is left with the impression that something might be fundamentally wrong with the premises underlying the doctrine of physics applicable today, which is preventing a solution of these problems from being found. As a possible cause, the author proposes that the gravitation of the photons is not so negligible that it can be completely ignored (although this assumption does not accord with the current state of physics). Departing therefore from the accepted doctrine, he assumes that gravitation might possess a hitherto unknown important influence on electromagnetism. This paper then examines the consequences of this assumption on physics. A precise analysis will lead to the insight that the gravitation of a photon is as dynamic as the photon itself, and therefore must be taken into account with all associated physical considerations. The hitherto accepted case of a static gravitation of photons, on the other hand, can be totally neglected, as it does not exist for photons. Of key importance is the statement that the gravitation of photons is produced by gravitational quanta, and thus appears in quantised form. It is therefore necessary to rethink the physics of photons. This leads to a number of other interesting insights, as will be borne out in the further course of this paper. In the event that the assumption of the influence of gravitation on electromagnetism turns out to be correct, then this would represent a major step in unravelling the still largely unknown nature of gravitation and its significance in the natural events of the microcosmos; furtheron it would be an important contribution regarding a “New Physics” and a “New Cosmology”.
The “Dynamic Gravitation of Photons: A Hitherto Unknown Physical Quantity”. New Aspects on the Physics of Photons  [PDF]
Guido Zbiral
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.55030
Abstract:

In order to explore the nature of photons, no doubts can be allowed to exist concerning the “physics of photons”. While static gravitation plays no role in the physics of photons, this paper will show that the previously unknown nonbaryonic dynamic gravitation of photons determines not only the external physical behaviour of photons but also, in particular, the hitherto unknown physical events occurring within the photons themselves. For this reason, the paper places particular emphasis on dynamic gravitation as a new hitherto unknown physical quantity. Moreover the new type of gravitation postulated here also provides a plausible explanation of the mysterious nonbaryonic dark matter. As no generally accepted scientific explanation of the creation and essence of dark matter exists to date, it is to be anticipated that the nonbaryonic dynamic gravitation of photons is of general interest to physicists as well as cosmologists and may serve to initiate a general debate among them. Furthermore, this paper will also show that there exists a close mutual relationship between electrodynamics <> dynamic gravitation <> static gravitation <> electrostatics <> electrodynamics (refer to paragraph 4). Due to the fact that the insights into the relationship between photons and their dynamic gravitation have not been described by any other author to date, there exists only a few references that I can cite in support of my paper.
