Abstract: Se realizó un estudio descriptivo y transversal de 340 personas divididas en 2 grupos, con y sin antecedentes patológicos familiares de diabetes mellitus tipo 2 (APF de DM2), con el objetivo de detectar si las que presentaban APF de DM2 tenían más hiperinsulinemia, presencia de síndrome metabólico, factores de riesgo cardiovascular asociados y lesión de órganos diana, expresados en hipertrofia del ventrículo izquierdo de los sujetos que no tenían dicho antecedente. Se obtuvo como resultado que la hiperinsulinemia estuvo presente en 96 pacientes con APF de DM2 (56,5 %) y una significación de p = 0,001. El síndrome metabólico fue más frecuente en las personas con APF DM2 (90) para un 52,9 % y una significación de p = 0,000. La hipertrigliceridemia fue el marcador por excelencia del síndrome metabólico y el factor de riesgo que con más significación estadística se asoció a los sujetos con APF de DM2 (96: 52,9 % y una significación de p = 0,000). La hipertrofia ventricular izquierda (HVI) se asoció como expresión de lesión de órganos diana a los sujetos con APF de DM2 (36: 21,2 % y una significación de p = 0,043). Concluimos que los sujetos con APF de DM2 son más propensos a tener hiperinsulinemia, al síndrome metabólico, a factores de riesgo cardiovascular y a lesión de órgano diana en comparación con los que no tienen dicho antecedente. A cross-sectional descriptive study of 340 persons assigned to two groups, with and without family history of diabetes mellitus type 2 (DM2), was carried out. The objective was to detect whether those persons with family history of DM2 had more hyperinsulemia, metabolic syndrome, associated cardiovascular risk factors and target organ lesions, expressed in left ventricle hypertrophy, than subjects without diabetes family history. The result was that hyperinsulemia was present in 96 patients with family history of DM2 (56,5 %) and significance level of p= 0,001. Metabolic syndrome was more frequent in subjects with family history of DM2 (90) for 52,9 % of cases and p= 0,000. Hypertriglyceridemia was both the most noticeable marker of the metabolic syndrome and the most statistically significant risk factor in subjects with family history of DM2 (96 , 52,9 % of cases and p= 0,000). Left ventricle hypertrophy was associated as target organ lesion expression to subjects with family history of DM2 (36: 21,2 % and p=0,043). It was concluded that subjects with family history of DM2 are more likely to have hyperinsulinemia, metabolic syndrome, cardiovascular risk factors and target organ lesions than those persons without such a f

Abstract: since the insulin resistance syndrome or x syndrome was identified by gerald m. reaven in his brilliant lecture for banting′s medal in new orleans, it has comprised several names and concepts. this syndrome is characterized by insulin resistance condition (ir), hyperinsulinemia and chronic inflammation and defines a metabolic condition causing a reduction in the ability of the human being to respond to physiological concentrations of insulin hormone in addition to present chronic inflammation. the insulin resistance syndrome is associated to metabolic alterations such as pre-diabetes and diabetes mellitus type 2 (dm2), dyslipidemia, blood hypertension and risk of developing cardiovascular diseases. also, altered hemostasis, central adiposity, non-alcoholic fat liver, cancer and hyperuricemia are elements included in this syndrome nowadays. additionally, insulin resistance found in girls prior to menarche is involved in the pathogenesis of polycystic ovary syndrome (pos) that is a disorder characterized by menstruation irregularities and excessive amount of androgens. insulin resistance syndrome is a predominant disorder whose pathogenesis is influenced by genetic and environmental factors. excessive intake of calories together with lack of exercising leads to phenotypical expression of this syndrome in individuals with genetic predisposition. this article emphasized the relationship of the metabolic syndrome and the polycystic ovary syndrome from the clinical, physiopathological, epidemiological and preventive viewpoints.

Abstract: Desde que fue identificado el Síndrome de insulinorresistencia (SIR), o Síndrome X por Gerald M. Reaven en su brillante conferencia por la medalla de Banting, en New Orleans, desde entonces el síndrome ha tenido una variación de nombres y conceptos. Este síndrome se caracteriza por un estado de insulinorresistencia (IR), hiperinsulinemia e inflamación crónica y se refiere a una condición metabólica caracterizada por una disminución en la capacidad de respuesta del ser humano a concentraciones fisiológicas de la hormona insulina, además de la inflamación crónica presente. El SIR se asocia con alteraciones metabólicas como la prediabetes y la diabetes mellitus tipo 2 (DM2), dislipidemia, hipertensión arterial y riesgo para desarrollar una enfermedad cardiovascular. Una hemostasis alterada, adiposidad central, hígado graso no alcohólico (HGNA), cáncer, e hiperuricemia son componentes en la actualidad de este síndrome. También en las mujeres jóvenes de edad premenárquica, la insulinorresistencia está involucrada en la patogénesis del síndrome de ovarios poliquísticos (SOP), un trastorno caracterizado por irregularidad menstrual y exceso de andrógenos. El SIR es un trastorno muy prevalente con factores tanto genéticos como ambientales que están implicados en su patogénesis. Una ingestión excesiva de calorías, combinada con una vida sedentaria, promueve la expresión fenotípica de este síndrome en individuos con predisposición genética. Se hace énfasis en la relación entre el síndrome metabólico y el de ovarios poliquísticos, tanto desde el punto de vista clínico y fisiopatológico, como epidemiológico y preventivo.

Abstract: Plant-associated bacteria that inhabit the rhizosphere may influence the plant growth by their contribution to the endogenous pool of phytohormones and by the activity of ACC deaminase to decrease the ethylene concentration. The aim of this study was to analyse the root length growth by the promoting effect of indole acetic acid producers phytobacteria with ACC deaminase activity, on inoculated seeds of Lens esculenta as synergistic effect on root elongation. In this study, although the roots of L. esculenta seedlings do not show a significant promotion, these phytobacteria could be recommended to treat plants analyzing their added inoculum to increase plant biomass and retard the effect of ethylene on cultures supplied with Tryptophan and ACC.

Abstract: Se presenta el caso clínico de un recién nacido a término por parto distócico (cesárea), debido a una toxemia gravídica, con antecedente de polihidramnios, que manifestó dificultad respiratoria a los pocos minutos del nacimiento y fue ingresado en el Hospital Infantil Norte "Dr. Juan de la Cruz Martínez Maceira" de Santiago de Cuba. Le fueron detectadas cifras de glucemia muy bajas que, evolutivamente, trajeron aparejadas convulsiones tónico-clónicas generalizadas, cuyas frecuencias no se lograban disminuir. Se le diagnosticó una hipoglucemia hiperinsulínica persistente (nesidioblastosis) y fue trasladado a La Habana para recibir tratamientos clínico y quirúrgico definitivos. Actualmente es atendido por un equipo médico multidisciplinario. The case of a term infant by dystocia (cesarean section) due to pregnancy toxemia with history of polyhydramnios is presented, who had respiratory distress a few minutes after birth and he was admitted to "Dr. Juan de la Cruz Martínez Maceira" Northern Children Hospital of Santiago de Cuba. Very low blood glucose levels were detected that progressively caused tonic-clonic seizures, which frequencies could not be reduced. He was diagnosed with persistent hyperinsulinemic hypoglycemia (nesidioblastosis) and was transferred to Havana to receive definitive clinical and surgical treatments. Currently, he is treated by a multidisciplinary medical team.

Revista Facultad de Ingeniería - Universidad de Tarapacá , 2005, DOI: 10.4067/S0718-13372005000200007
Abstract: a self balancing system analysis is presented which utilizes freely moving balancing bodies (balls) rotating in unison with a rotor to be balanced. using lagrange′s equation, we derive the non-linear equations of motion for an autonomous system with respect to the polar coordinate system. from the equations of motion for the autonomous system, the equilibrium positions and the linear variational equations are obtained by the perturbation method. because of resistance to motion, eccentricity of race over which the balancing bodies are moving and the influence of external vibrations, it is impossible to attain a complete balance. based on the variational equations, the dynamic stability of the system in the neighborhood of the equilibrium positions is investigated. the results of the stability analysis provide the design requirements for the self balancing system.
