Abstract: The mood disorders are characterized by alterations in the person's general emotional state. Depression is one of the most common mood disorders experienced by elderly. Depression in elderly has different characteristics than in other life cycle stages. In the process of aging, physical changes can be confused with depressive symptoms. The physiological changes, psychological, social and environment factors are important for the development of depression. Likewise, depressive symptoms in old age have been associated with morbidity, physical dependence, cognitive impairment and dementia. The aim was to determine the prevalence of depression symptoms and its relationship with socio-demographic factors, cognitive function, co-morbidity and physical disabilities among elderly in a Mexican community setting. The Inter-institutional Dementia Project in Jalisco (CONACYT 7994) was taken as the basis for this chapter. This is a cross-sectional study, multi-stage, random, and proportional with the participation of n=2,553 community-dwelling elders 60 and older. A battery of assessment was applied during an interview in which different areas were assessed: Depression (30-item GDS), cognitive function (MMSE), functional status (ADL, IADL), chronic medical conditions and vital risk factors (self-report). The questionnaire included also socio-demographic factors. Data obtained were validated and entered into a database. Crude Odds Ratio and confidence interval of 95% were calculated. Logistic regression models tested the relative contributions of demographic variables, diseases and impairments, and general conditions on depression. It was found a prevalence of 30.9% depressive symptomatology. Mean age of participants was 71.6 8.7 years, mostly women (61.2%). Education level was low, mean was 3.6 3.8 years of education, illiterate 27.2%. 45.5% had no couple, widowed 32.3%, single 8.6%, and divorced 4.6%. Were mainly housewives (41.7%), and 79.2% not pensioners. Functional disability prevalence was 31.5% for IADL, 9.6% in ADL, and 14.3% had cognitive impairment. A mean of 1.5 for chronic diseases was reported. Depressive symptoms were associated in bivariate analysis with being female, cognitive impairment, ADL and IADL disability, co-morbidity, education and being married. Increased age was not related. These results orient to the necessity of prevention and control of the depression in the primary care and to recognize it as a problem of public health. This study gives us the possibility not only to establish a diagnosis and treatment, but also to promote healthy lifestyles and prevention of depression in older people in order to remain active as long as possible and to improve their quality of life.

Hough, M.M.",,"2009",,"Embryonic stem cells (ESCs) represent permanent cell lines that can be maintained in an undifferentiated state. In an environment that induces differentiation, they form derivatives of the three embryonic germ layers: mesoderm, ectoderm, and endoderm. These characteristics give ESCs great potential for both basic research and clinical applications in the areas of regenerative medicine and tissue engineering. The establishment of ESCs from large animals that model human diseases is of significant importance. We describe the derivation of permanent canine cell lines from preimplantation- stage embryos. Similar to human ESCs, canine ESCs expressed OCT3/4, NANOG, SOX2, SSEA-3, SSEA-4, TRA-1-60, TRA-1-81, and alkaline phosphatase, whereas they expressed very low levels of SSEA-1. They maintained a normal karyotype and morphology typical of undifferentiated ESCs after multiple in vitro passages and rounds of cryopreservation. Plating cells in the absence of a feeder layer, either in attachment or suspension culture, resulted in the formation of embryoid bodies and their differentiation to multiple cell types. In vivo, canine ESCs gave rise to teratomas comprising cell types of all three embryonic germ layers. These cells represent the first pluripotent canine ESC lines with both in vitro and in vivo differentiation potential and offer the exciting possibility of testing the efficacy and safety of ESC-based therapies in large animal models of human disease.",,,,,,"10.1634/stemcells.2008-0433",,,"http://hdl.handle.net/20.500.12104/40536","http://www.scopus.com/inward/record.url?eid=2-s2.0-62549145354&partnerID=40&md5=d7c81fb6ae573090eb642a4dda57f7ce",,,,,,"2",,"Stem Cells",,"329

Manero, O.",,"2014",,"In this work, we demonstrate that the thermodynamic potential calculated from the steady-state flow curve using the definition of free energy from irreversible thermodynamics, and the mechanical potential derived from the generalized BMP constitutive equation provide the same information in the unstable and metastable regions of the flow curve. The contribution of normal stresses in both potentials as well as its weight on the position of the stress plateau are explicitly exposed. The plateau stress is univocally defined by the location of the critical shear rates corresponding to the minima in the potential. This demonstration is carried out using experimental data of wormlike micellar solutions for various concentrations and temperatures, including regions close to the non-equilibrium critical point. A method to accurately determine the non-equilibrium critical point (or the critical temperature) in a direct form is provided here. Bifurcation points are defined, notably one located at the high shear-rate branch of the flow curve separating the regions of one real solution and three real solutions. The first normal stress difference exhibits three real solutions as sources of elastic instabilities in the high shear band. The contribution of the second normal-stress difference in both the mechanical and thermodynamic potentials is clearly exposed. These results demonstrate that the non-equilibrium phase transition and the mechanical instability as sources of the banded flow are essentially two manifestations of the same reality.
