Medir y monitorear la resiliencia de los sistemas agrosilvopastoriles de pequeños productores es cada vez más urgente para ayudarles a enfrentar de mejor manera los efectos del clima cambiante. Aunque se reconocen otras formas de medir la resiliencia climática, la novedosa herramienta SHARP desarrollada por la FAO permite su identificación, medición y la priorización de acciones para mejorarse de una manera participativa, tomando en cuenta los intereses de los productores. En coordinación con el ...

The selection of a medical specialty has been associated with multiple factors, such as personal preferences, academic exposure, motivational factors and sociodemographic factors, such as gender. The number of women in the medical field has increased in recent years. In Latin America, we have not found any studies that explore this relationship.To determine whether there is an association between gender and the intention to choose a medical specialty in medical students from 11 countries in Latin ...

In recent decades, both academia and industry have shown noteworthy interest in investigating the semiconducting properties of graphene. Nevertheless, the lack of a suitable bandgap in graphene has restricted its practical applications in the current semiconductor industry. To overcome this limitation, graphene micro/nano-strips have been actively explored. The focus of the present study centers on modeling the electronic and plasmonic characteristics of graphene strips with varying widths: 2.7, ...

Abstract Background Compared to their white counterparts, Latina breast cancer survivors experience poorer quality of care and worse health-related quality of life. Limited English proficiency (LEP) and patient engagement in cancer care could help explain these disparities. We assessed associations between LEP status and difficulty engaging with physicians, with self-reported quality of breast cancer care and health-related quality of life (physical and emotional well-being) among rural and urban ...

Abstract The mechanics of phase transforming cellular materials (PXCMs) with three different chiral honeycomb architectures, viz., hexachiral, tetra-anti-chiral, and tetra-chiral, are investigated under quasi-static loading/unloading. Each PXCM comprises interconnected unit cells consisting of tape springs rigidly affixed to circular nodes that can rotate and/or translate. The phase change is associated with snap-through instability due to bending of the tape springs and corresponds to sudden changes ...

The composition and trophic structure of their fish assemblages have never been characterized in detail, and the aim of this study was therefore to analyse the community structure and assess the similarity of fish assemblages between these two areas. Underwater visual fish censuses were conducted using band transects at two depth levels in three islands of the Revillagigedo Archipelago ( ...

Human abdominal angiostrongyliasis is a zoonotic disease caused by ingestion of the L3 larvae of Angiostrongylus costaricensis. The human infection gives rise to a pathological condition characterized by acute abdominal pain, secondary to an inflammatory granulomatous reaction, marked eosinophilia and eosinophilic vasculitis. Most commonly this disease is limited to intestinal location, primary ileocecal, affecting the mesenteric arterial branches and intestinal walls. We present one of the few ...

Multi-hazard evaluations are fundamental inputs for disaster risk management plans and the implementation of resilient urban environments, adapted to extreme natural events. Risk assessments from natural hazards have been typically restricted to the analysis of single hazards or focused on the vulnerability of specific targets, which might result in an underestimation of the risk level. This study presents a practical and effective methodology applied to two Chilean coastal cities to characterize ...

Rivers in northern Chile have arsenic (As) concentrations at levels that are toxic for humans and other organisms. Microorganism-mediated redox reactions have a crucial role in the As cycle; the microbial oxidation of As (As(III) to As(V)) is a critical transformation because it favors the immobilization of As in the solid phase. We studied the role of microbial As oxidation for controlling the mobility of As in the extreme environment found in the Chilean Altiplano (i.e., > 4000 meters above sea level ( ...

This approach allows us to overcome the classical distinction between naturalist and normativist approaches in the philosophy of medicine, taking into account both the material and the symbolic ...

The current contribution of wild animal proteins has been poorly quantified, particularly in the rapidly growing urban centers of tropical forests. Lack of such evidence impairs food security strategies to include the diversity of food supply inherent to traditional food systems. In this study we focus on wild sources of animal protein: wild fish and bushmeat, which have traditionally been important in people’s diets in the Amazon. We analyze their consumption frequencies as compared to domestic ...

Compared to their White counterparts, Latina breast cancer survivors have poorer survival rates and health-related quality of life, and higher rates of depression and anxiety which may be a result of chronic stress. Chronic stress impacts the hypothalamic-pituitary-adrenal (HPA) axis, resulting in cortisol dysregulation which may be associated with breast cancer survival. However, cortisol levels and cortisol profiles of Latina breast cancer survivors are poorly characterized due to their underrepresentation ...

Results showed that acid modified the ...
