Diabetes mellitus type 2 (DM2) is the leading cause of death in people from 15 to 64 years in Mexico, and other regions in the world. For the chronic nature of diabetes and complications caused by inadequate metabolic control, patients may have mood disorders such as depression. Several studies have demonstrated higher prevalence of depression in diabetic patients than in general population. Our objective: is to determine prevalence and factors associated with depressive disorder in patients with type 2 diabetes mellitus enrolled in DiabetIMSS during 2010. Analytical study with random probability sampling. The analysis included prevalence, odds ratios with 95% confidence intervals. The Center Epidemiological Studies Depression Instrument was used. Prevalence of depression was 32.7% at 95% CI = 26.4-38.9%), 67.3% for women, 32.7 % for men; good metabolic control was 51.9%, CI = 95% (45.13-58.66%). We found a higher prevalence of depressive disorders than in the general population, no statistical association with glycemic control, keeping a greater proportion of women as well as the main aspect of depression associated with the perception of emotional support. We discuss DiabetIMSS program effectiveness. Source

We make use of O(2r + 1) spinning particle models to construct linearized higher-spin curvatures in (A)dS spaces for fields of arbitrary half-integer spin propagating in a space of arbitrary (even) dimension: the field potentials, whose curvatures are computed with the present models, are spinor-tensors of mixed symmetry corresponding to Young tableaux with D/2-1 rows and r columns, thus reducing to totally symmetric spinor-tensors in four dimensions. The paper generalizes similar results obtained in the context of integer spins in (A)dS. © SISSA 2010. Source

According to ethnographic material collected since 2003, the Chol Mayan indigenous people in southern Mexico have different causal explanations for suicide. It can be attributed to witchcraft that forces victims to take their lives against their own will, to excessive drinking, or to fate determined by God. However, it can also be conceived of as a conscious decision made by a person overwhelmed by daily problems. Drawing from the theoretical framework developed by Laura M. Ahearn, inspired by practice theory, the paper contends that these different explanations operate within two different logics or understandings of human agency. The first logic attributes responsibility to supernatural causes such as witchcraft or divine destiny, and reflects Chol notions of personhood. The second logic accepts personal responsibility for suicide, and is related to processes of social change such as the introduction of wage labor, education and a market economy. The contemporary Chol resort to both logics to make sense of the human drama of suicide. © 2012 Springer Science+Business Media, LLC. Source

We analyze the possible effects arising from the Planck scale regime upon the interference pattern of two noninteracting Bose-Einstein condensates. We start with the analysis of the free expansion of a condensate, and have taken into account the effects produced by a deformed dispersion relation, suggested in several quantum-gravity models. The analysis of the condensate free expansion, in particular, the modified free velocity expansion, suggests in a natural way, a modified uncertainty principle that could lead to new phenomenological implications related to the quantum structure of space-time. Finally, we analyze the corresponding separation between the interference fringes after the two condensates overlap, in order to explore the sensitivity of the system to possible signals caused by the Planck scale regime. © 2015 American Physical Society.

Raoiella indica (Acari: Tenuipalpidae) is a phytophagous mite that recently invaded the Neotropical region. A predatory mite Amblyseius largoensis (Acari: Phytoseiidae) has been found associated with R. indica in Florida. This study evaluated A. largoensis by determining its likelihood of consuming eggs and larvae of R. indica and Tetranychus gloveri (Acari: Tetranychidae) under no-choice and choice conditions. To detect variations in the response of A. largoensis to R. indica, four populations of predators were examined: (1) predators reared exclusively on R. indica in the laboratory for 2. years, (2) predators reared on T. gloveri in the laboratory for 2. months but reared on R. indica for 2. years previously, (3) predators collected from a field infested with R. indica, and (4) predators collected from a field that had never been infested with R. indica. Results of this study suggest that A. largoensis is likely to accept and consume high numbers of R. indica eggs regardless of their previous feeding experience. In contrast, all populations consumed relatively fewer R. indica larvae than the other prey tested. Predators previously exposed to R. indica were more likely to consume R. indica larvae. By contrast, predators not previously exposed to R. indica showed the lowest likelihood of choosing to feed on this prey item. Plasticity in the response of A. largoensis to R. indica larvae could be associated to selection, learning, or a combination of both. The possible implications of the observed differences in terms of biological control of R. indica are discussed. © 2011 Elsevier Inc. Source
