ABSTRACT
Objetivo: Relacionar los niveles séricos de adiponectina con el estado nutricional y resistencia a la insulina (RI) en adultos con o sin síndrome metabólico (SM), pertenecientes a la cohorte CDC de Canarias en Venezuela. Métodos: La muestra incluyó 62 adultos Canarios e hijos residentes en Venezuela. Se efectuó antropometría, determinación de presión arterial, análisis sérico de: glucosa, HDL-colesterol, triglicéridos, insulina y adiponectina. Resultados: La adiponectina fue significativamente inferior, comparado con los controles, en obesos, (2,16 ± 0,51 ng/ml vs. 2,62 ± 0,42 ng/ml, p =0,032) y sujetos con SM (1,85 ± 0,46 ng/ml vs. 2,55 ± 0,43 ng/ml, p =0,000). La adiponectina mostró una correlación inversa con edad, presión arterial diastólica así como con los indicadores de RI (HOMA, índice triglicéridos / HDL-colesterol y trigliceridemia). Conclusión: En la totalidad de la muestra, los sujetos mostraron hipoadiponectinemia, implicando alto riesgo cardiovascular, que podría explicarse parcialmente por la presencia de obesidad, SM, RI o relacionado con mayor edad que incrementa el riesgo de estrés oxidativo.
Objective: To relate serum adiponectin levels with nutritional status and insulin resistance (IR) in adults with and without metabolic syndrome (MS) cohort belonging to the CDC de Canarias en Venezuela. Methods: The sample included 62 people, Canaries and children living in Venezuela. Anthropometry, blood pressure determination, analysis of fasting serum glucose, HDL-cholesterol, triglycerides, insulin and adiponectin, were performed. Results: Serum levels of adiponectin were significantly lower in individuals with obesity (2.16 ± 0.51 vs 2.62 ± 0.42, p = 0.032) and subjects with MS (1.85 ± 0.46 vs 2.55 ± 0.43 p = 0.000), compared to respective control group. Pearson analysis showed an inverse correlation of adiponectin with age, diastolic blood pressure as well as indicators of insulin resistance (HOMA, index triglycerides, HDL-cholesterol and triglycerides). Conclusion: In the whole sample, the subjects showed low serum adiponectin, implying a high cardiovascular risk, which could be partially explained by the presence of obesity, MS, RI or related to older age that increases the risk of oxidative stress.
ABSTRACT
We present the results of a paleoparasitologic, paleogenetic and paleobotanic analysis of coprolites recovered during the excavation of the church La Concepción in Santa Cruz de Tenerife. Coprolites (n = 4) were rehydrated and a multidisciplinary analysis was conducted. The paleobotanic analysis showed numerous silicates, seeds and fruits of the family Moraceae. In the paleoparasitologic study, Ascaris sp. eggs (n = 344) were identified. The paleogenetic results confirmed the Ascaris sp. infection as well as the European origin of human remains. These findings contribute to our knowledge of ancient helminthes infections and are the first paleoparasitological record of Ascaris sp. infection in Spain.

Six novel polymorphic microsatellite markers were isolated from enriched libraries in Myrica faya Ait., recently renamed Morella faya, (fayatree, firetree, or firebush) in order to examine the genetic diversity in natural populations. Also, test cross-specific amplification and genetic diversity in Myrica rivas-martinezii, which is endemic on the Canary islands. Microsatellite loci were screened in 225 individuals of both species from different islands of the Canarian archipelago. All markers were successfully amplified from both Myrica species, with an average number of 6.5 and 9.3 alleles per locus in M. rivas-martinezii and M. faya, respectively. There was no evidence for linkage disequilibrium between loci, and the probability of null alleles ranged from 0.01 to 0.17.
