Physico-chemical study of the radiopharmaceuticals 99mTc-DMSA, 99mTc-EDTA and 99mTc-DTPA interaction with plasmatic proteins.
1989
This report studies the binding rate of the radiopharmaceuticals 99mTc-DTPA, 99mTc-EDTA and 99mTc-DMSA to plasmatic proteins. The proteins bind to the tested radiopharmaceuticals in the following sequence: 99mTc-DTPA less than 99mTc-DMSA(C1) less than 99mTc-EDTA less than 99mTc-DMSA(C2) where C1 and C2 represent two different Tc-DMSA complexes. The thermodynamic study suggests a quantitative relationship of radiopharmaceutical:protein = 1:1 and an almost nonexistent influence of the temperature, which means that the interacting forces in this process are relatively weak.
¿Un servicio civil de donación de sangre? En torno a una propuesta de Cécile Fabre | A civilian service of blood donation? On a Cécile Fabre?s propos…
2019
Resumen: En su libro Whose Body is it Anyway? Justice and the Integrity of the Person, Cécile Fabre defiende que, en nombre de la justicia, los recursos de una sociedad deben redistribuirse entre los necesitados y que, entre esos recursos, está incluida la sangre humana, para cuya provisión propone la creación de un servicio civil obligatorio de donación de sangre. Lo que se hace aquí es examinar si, a pesar de lo paradójica que pueda resultar, cabría desarrollar su propuesta en nuestro país.
 Abstract: In her book Whose Body is it Anyway? Justice and the Integrity of the Person, Cécile Fabre argues that, on behalf of justice, resources of a society should be redistributed to the needy…
Current and birth weights exert independent influences on nocturnal pressure-natriuresis relationships in normotensive children
1998
The objective was to study the impact of birth weight on the relationship between ambulatory blood pressure and urinary sodium excretion in children and adolescents. The study included 134 healthy children (61 boys), all Caucasians, who were born at term after a normotensive pregnancy. For each subject, a 24-hour ambulatory blood pressure monitoring and a complete urine collection were simultaneously performed according to the protocols designed. Average ambulatory blood pressure (BP) and the urinary excretion rates for sodium, potassium, and creatinine were calculated separately for 24-hour, awake, and sleep periods defined by a mini-diary. The excretion rate of sodium during sleep time wa…
Innovative in vitro method and permeability estimation procedure to predict drug transport across the blood-brain barrier
2014
La Barrera Hematoencefálica (BHE) es una entidad caracterizada por su naturaleza restrictiva al paso de sustancias. Las propiedades de la barrera están determinadas por la confluencia de tres componentes principales: 1) uniones celulares endoteliales con presencia de proteínas especificas intramembrana y citoplasmáticas unidas estrechamente al citoesqueleto. Esta circunstancia restringe la difusión paracelular de compuestos. Adicionalmente a las células endoteliales, la barrera presenta una membrana basal, en la cual se localizan pericitos y astrocitos, que conforman una capa que refuerza las propiedades de la barrera; 2) la presencia de transportadores de absorción y la sobreexpresión de t…
Posttraumatic carotid-cavernous fistula: Pathogenetic mechanisms, diagnostic management and proper treatment. A case report.
2016
Journal Article; UNLABELLED Carotid-cavernous fistulas are an uncommon diseases characterized by abnormal communications between arteries and veins located in the cavernous sinus. According with Barrow´s classification they could be divided in two groups: direct and indirect. The typical symptoms showed by theses pathologies are: pulsating exophthalmos and orbital blow. The present study describes a case of direct posttraumatic carotid-cavernous fistula in a 26 years old man. Furthermore, we present the images that we used to make the diagnosis. In this light, we decided to treat this case with endovascular approach after considering several therapeutic options. The aim of the present repor…

A uniform hieroglyphic : Further shades of meaning in Go Down, Moses.
1999
This essay offers a new interpretation of the role of Rider, the protagonist of “Pantaloon in Black”, within the context of Faulkner’s novel, Go Down, Moses. Although this character seems to be one of the least important in the book, he may really provide a pattem for Faulkner’s larger designs. Rider’s obsesgion with bis dead wife, Niannie, the appearance of her ghost, and bis struggle, against bis own vitality, to die and rejoin her can be read as a parallel to Isaac Mc Caslin’s initiation into a dead Indian culture based on spiritual rather than materialistic values, and as a foreshadowing of Ike’s eventual renunciation of his birthright, the McCaslin plantation. The final implication is …
CT angiography for the assessment of EVAR complications : a pictorial review
2022
Aortic aneurysm; Blood vessel prosthesis implantation; Endovascular procedures Aneurisma aórtico; Implantación de prótesis de vasos sanguíneos; Procedimientos endovasculares Aneurisma aòrtic; Implantació de pròtesis de vasos sanguinis; Procediments endovasculars Endovascular aneurysm repair (EVAR) is a minimally invasive treatment proposed as an alternative to open repair in patients with abdominal aortic aneurysms. EVAR consists in a stent-graft placement within the aorta in order to exclude the aneurysm from arterial circulation and reduce the risk of rupture. Knowledge of the various types of devices is mandatory because some stents/grafts are more frequently associated with complication…
Comparative Analysis of Machine Learning Methods to Predict Growth of F. sporotrichioides and Production of T-2 and HT-2 Toxins in Treatments with Et…
2021
The efficacy of ethylene-vinyl alcohol copolymer films (EVOH) incorporating the essential oil components cinnamaldehyde (CINHO), citral (CIT), isoeugenol (IEG), or linalool (LIN) to control growth rate (GR) and production of T-2 and HT-2 toxins by Fusarium sporotrichioides cultured on oat grains under different temperature (28, 20, and 15 °C) and water activity (aw) (0.99 and 0.96) regimes was assayed. GR in controls/treatments usually increased with increasing temperature, regardless of aw, but no significant differences concerning aw were found. Toxin production decreased with increasing temperature. The effectiveness of films to control fungal GR and toxin production was as follows: EVOH…
Polyoxypregnanes as safe, potent, and specific ABCB1-inhibitory pro-drugs to overcome multidrug resistance in cancer chemotherapy in vitro and in vivo
2021
Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of Marsdenia tenacissima (M. tenacissima) were novel ABCB1-modulatory pro-drugs, which underwent intestinal microbiota-mediated biotransformation in vivo to generate active metabolites. The metabolites at non-toxic concentrations restored chemosensitivity in ABCB1-overexpressing cancer cells v…
