    A través de la historia, se ha desarrollado una economía dinámica que permite de manera paulatina el surgimiento de las diversas sociedades, bajo el respaldo de la palabra y buena fe de las personas como principios de honor y de respeto, que secuencialmente era materializado en un documento como cartas pergaminos, etc; sin embargo, el cambio vertiginoso de los negocios origino la necesidad de utilizar  monedas y billetes, fundamentales para las transacciones que se dan hoy en día. Luego, con el paso del tiempo, se genera la demanda de documentos representativos de entidades financieras que gozan en el momento de credibilidad, prestigio y un reconocimiento en nuestra sociedad, como son los llamados títulos valores, pagaré, CDT, entre otros, los cuales comprometen hoy en día a las firmas - escritos de las personas y/o corporaciones bancarias. Así pues, esto propicio diferentes modalidades delictivas desde el punto de vista del fraude procesal, suplantación de personas, la falsedad de documentos públicos y privados, creando una problemática social para el Estado Colombiano, el cual desafortunadamente refleja una inseguridad financiera que en muchos casos, sumado a ello el sistema jurídico actual, no garantiza una justicia firme para penalización de esta clase delitos, debido a que las penas son  flexibles e irrisorias, generando la proliferación de los delitos de orden financiero. Por lo anterior, nace la motivación de realizar estudios cuyos resultados generen estrategias para contrarrestar y minimizar las modalidades relacionadas con la falsedad de firmas y escritos en documentos bancarios que comprometen a los usuarios y a las entidades financieras, respaldadas debidamente por las instituciones públicas y de control por parte del Gobierno Nacional

    Type 2 Diabetes Variants Disrupt Function of SLC16A11 through Two Distinct Mechanisms

    Type 2 diabetes (T2D) affects Latinos at twice the rate seen in populations of European descent. We recently identified a risk haplotype spanning SLC16A11 that explains ∼20% of the increased T2D prevalence in Mexico. Here, through genetic fine-mapping, we define a set of tightly linked variants likely to contain the causal allele(s). We show that variants on the T2D-associated haplotype have two distinct effects: (1) decreasing SLC16A11 expression in liver and (2) disrupting a key interaction with basigin, thereby reducing cell-surface localization. Both independent mechanisms reduce SLC16A11 function and suggest SLC16A11 is the causal gene at this locus. To gain insight into how SLC16A11 disruption impacts T2D risk, we demonstrate that SLC16A11 is a proton-coupled monocarboxylate transporter and that genetic perturbation of SLC16A11 induces changes in fatty acid and lipid metabolism that are associated with increased T2D risk. Our findings suggest that increasing SLC16A11 function could be therapeutically beneficial for T2D.

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
