Revista Cubana de Investigaciones Biom??dicas , 2012,
Abstract: Es frecuente que en pacientes con enfermedad inflamatoria intestinal se observen cambios analíticos o clínicos que indican la existencia de una enfermedad hepatobiliar. La frecuencia de estos hallazgos oscila entre 11-49 % en colitis ulcerosa y entre 15-30 % en enfermedad de Crohn. En algunos casos, estas alteraciones se observan desde el primer momento en que se estudia a los pacientes, otras surgen en el curso de la enfermedad. Se realizó un estudio descriptivo observacional retrospectivo donde se incluyó 180 pacientes con enfermedad inflamatoria intestinal, que se atienden en el Instituto de Gastroenterología, de ellos con manifestaciones hepatobiliares, 17 pacientes (9,4 %), 12 colitis ulcerosa y 5 Crohn. Las variables estudiadas fueron: sexo, edad, a os de evolución según tipo de enfermedad inflamatoria, tipo de manifestación hepatobiliar, síntomas clínicos, estudio de enzimas hepáticas y hallazgos ultrasonográficos. Se concluyó que existe predominio de pacientes con colitis ulcerosa. Predominó el sexo femenino en la colitis ulcerosa; el Crohn no tuvo variaciones significativas. La edad estuvo comprendida entre 30 y 49 a os. La manifestación hepatobiliar más frecuente en el Crohn fue la hepatopatía de etiología no filiada y en la colitis ulcerosa la colangitis esclerosante primaria. El síntoma clínico que predominó en ambos grupos fue la astenia, y en la colitis ulcerosa también predominó el prurito e íctero. Con respecto a las enzimas bioquímicas predominó la hipertransaminasemia, y por ultrasonido el aspecto granular y aumento de la ecogenicidad hepática. It is common for patients with inflammatory bowel disease to present analytical or clinical changes pointing to the presence of hepatobiliary disease. The frequency of such findings ranges between 11-49 % in ulcerous colitis and between 15-30 % in Crohn's disease. In some cases, the alterations are found when the patient is first examined, while in others they emerge during the course of the disease. An observational retrospective descriptive study was conducted of 180 patients with inflammatory bowel disease cared for at the Institute of Gastroenterology. Hepatobiliary manifestations were found in 17 patients (9.4 %): 12 with ulcerous colitis and 5 with Crohn's disease. The variables studied were sex, age, years of evolution by type of inflammatory disease, type of hepatobiliary manifestation, clinical symptoms, study of hepatic enzymes and ultrasonographic findings. There was a predominance of patients with ulcerous colitis. Female sex prevailed in ulcerous colitis. No significant differences
Protein phase instability developed in plasma of sick patients: clinical observations and model experiments  [PDF]

Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.23034
Abstract: This article discusses the causes of formation of micron-size protein structures in liquid plasma or serum of the patients with different diseases, which are accompanied by inflammatory reac-tions. Self-organizing processes in sessile dry-ing drops of natural and model biological liq-uids are used for study of possible mechanisms of development the protein phase instability in serum. There was shown that violation of opti-mal ratio between albumin and osmotic active components could lead to loss of albumin ag-gregative stability and albumin coagulation structures formation. Possible role of these structures in pathogenesis of inflammation is discussed.

Abstract: PURPOSE: The authors analyzed the 30-day and 6-month outcomes of 1,126 consecutive patients who underwent coronary stent implantation in 1996 and 1997. METHODS: The 30-day results and 6-month angiographic follow-up were analyzed in patients treated with coronary stents in 1996 and 1997. All patients underwent coronary stenting with high-pressure implantation (>12 atm) and antiplatelet drug regimen (aspirin plus ticlopidine). RESULTS: During the study period, 1,390 coronary stents were implanted in 1,200 vessels of 1,126 patients; 477 patients were treated in the year 1996 and 649 in 1997. The number of percutaneous procedures performed using stents increased significantly in 1997 compared to 1996 (64 % vs 48%, p=0.0001). The 30-day results were similar in both years; the success and stent thrombosis rates were equal (97% and 0.8%, respectively). The occurrence of new Q wave MI (1.3% vs 1.1%, 1996 vs 1997, p=NS), emergency coronary bypass surgery (1% vs 0.6%, 1996 vs 1997, p=NS) and 30-day death rates (0.2% vs 0.5%, 1996 vs 1997, p=NS) were similar. The 6-month restenosis rate was 25% in 1996 and 27% in 1997 (p= NS); the target vessel revascularization rate was 15% in 1996 and 16% in 1997 (p = NS). CONCLUSIONS: Intracoronary stenting showed a high success rate and a low incidence of 30-day occurrence of new major coronary events in both periods, despite the greater angiographic complexity of the patients treated with in 1997. These adverse variables did not have a negative influence at the 6-month clinical and angiographic follow-up, with similar rates of restenosis and ischemia-driven target lesion revascularization rates.

Abstract: Stress was once defined as the non-specific result of the body to any demand or challenge to homeostasis. A more current view of stress is the behavioral and physiological responses generated in the face of, or in anticipation of, a perceived threat. The stress response involves activation of the sympathetic nervous system and recruitment of the hypothalamic-pituitary-adrenal (HPA) axis. When an organism encounters a stressor (social, physical, etc.), these endogenous stress systems are stimulated in order to generate a fight-or-flight response, and manage the stressful situation. As such, an organism is forced to liberate energy resources in attempt to meet the energetic demands posed by the stressor. A change in the energy homeostatic balance is thus required to exploit an appropriate resource and deliver useable energy to the target muscles and tissues involved in the stress response. Acutely, this change in energy homeostasis and the liberation of energy is considered advantageous, as it is required for the survival of the organism. However, when an organism is subjected to a prolonged stressor, as is the case during chronic stress, a continuous irregularity in energy homeostasis is considered detrimental and may lead to the development of metabolic disturbances such as cardiovascular disease, type II diabetes mellitus and obesity. This concept has been studied extensively using animal models, and the neurobiological underpinnings of stress induced metabolic disorders are beginning to surface. However, different animal models of stress continue to produce divergent metabolic phenotypes wherein some animals become anorexic and lose body mass while others increase food intake and body mass and become vulnerable to the development of metabolic disturbances. It remains unclear exactly what factors associated with stress models can be used to predict the metabolic outcome of the organism. This review will explore a variety of rodent stress models and discuss the elements that influence the metabolic outcome in order to further extend our understanding of stress-induced obesity.

Abstract: it is reported the case of a dog with strangury, increased bladder volume and presence of a painless mass in the region of penis bone. the failure of urethral probing allowed the diagnosis of urinary obstruction. a regular contour mass, moving and obstructing the urethra, was observed in the radiographic examination. after surgical removal, the tissue was submitted to histopathologic analysis, which confirmed the diagnosis of aneurismal cyst of the penis - yet unreported disease in dogs.
Reflexiones acerca de las familias transfronterizas y las familias transnacionales entre México y Estados Unidos
Ojeda, Norma;
Frontera norte , 2009,
Abstract: this article presents a series of reflections about transborder and transnational families living near the mexico-u.s. border. these two different family types are not mutually exclusive, because some families belong to both. transborder families form part of a regional phenomenon unique to the two nation's geographic border and dating from its creation. transnational families fit into a broader social situation tied to both the migrant flow? between the two countries and the phenomenon of globalization. both types form part of the current family systems of mexico and the united states. one expects they will continue to increase in both size and social complexity on each side of the border.

Abstract: quebrada. las cordilleras en andas examines the issue of the artwork’s diminished status within a landscape dominated by the entertainment industry. from this knowledge and the vanguard design of the book itself -as an instrument of the real-arises a tension that is characteristic of contemporary art. this tension has been compared to the point of hysteresis of an element, in which like a magnetic material it, the work of art, preserves one of its properties in the absence of its stimulus. this essay examines how this tension is produced in the work by guadalupe santa cruz.
Visión de la obra de Salvador Garmendia desde la crítica literaria
Letras , 2010,
Abstract: on the basis of the importance of critical literary studies for the conformation and diffusion of the processes of construction of venezuelan cultural imagery, a vision of these is presented with regards to the literary work of salvador garmendia. in this sense, the opinions of liscano (1995), delprat (2004), jiménez (2007), among others, were considered. this study aimed at characterizing the work of garmendia from the view of current literary criticism. it is supported on fish?s theory (1989) that characterizes the critic as an "informed reader", producing a plurality of interpretations. this research is of a documentary nature and is supported on the analysis of the opinions expressed by literary critics on the garmendian work. among other things, one can conclude that the garmendian literature is innovative in its treatment of the city as element that affects man and is loaded with highly referential language.
