La política habitacional chilena se caracteriza por la localización sistemática de la vivienda social en la periferia urbana. Incluso la nueva política de 2001, que busca la integración urbana y social de los pobladores, financia en su mayoría la construcción de vivienda nueva en grandes conjuntos localizados en periferias recién urbanizadas. Una excepción es el proyecto de rehabilitación de la Población Obrera de la Unión, en el que los vecinos organizados y los diferentes actores implicados colaboran para rehabilitar integralmente el edificio. Esta experiencia demuestra que la decisión de los habitantes por permanecer viviendo en el inmueble y el trabajo conjunto con la administración pública pueden evitar que un edificio se demuela y permitir su rehabilitación. Abstract The article discusses the issue of participation of the inhabitants in the production of its habitat in relation to public policy in the Chilean context and in the particular case of the building of the working population in Valparaiso Union. The Chilean housing policy is characterized by the systematic location of social housing in the urban periphery. Even the new policy of 2001 which seeks urban and social integration of people, mostly financed the construction of new housing in large groups located in newly built suburbs. One exception is the rehabilitation project of the working population of the Union, which organized the neighbors and the different actors involved work together to fully rehabilitate the building. This experience demonstrates that the decision of the people to remain living in the building and working together with public administration can prevent demolish a building and enable their rehabilitation.

The genus Tarzetta is distributed mainly in temperate forests and establishes ectomycorrhizal associations with angiosperms and gymnosperms. Studies on this genus are scarce in México. A visual, morphological, and molecular (ITS-LSU) description of T. americupularis , T. cupressicola , T. davidii , T. durangensis , T. mesophila , T. mexicana , T. miquihuanensis , T. poblana , T. pseudobronca , T. texcocana , and T. victoriana was carried out in this work, associated with Abies , Quercus , and Pinus . The results of SEM showed an ornamented ascospores formation by Mexican Taxa; furthermore, the results showed that T. catinus and T. cupularis are only distributed in Europe and are not associated with any American host.

Background: Propofol is a short and rapidly acting intravenous anesthetic extensively used for the induction and maintenance of general anesthesia. It is a lipid emulsion that contains soybean oil, purified egg phosphatide, and egg lecithin. Therefore, the package leaflet indicates that its administration is contraindicated in patients allergic to soy, eggs, or peanuts. Our study aimed to determine whether patients with proven food allergies are allergic to propofol., Methods: Patients of all ages allergic to soy, eggs, or peanuts who agreed to undergo skin testing for propofol allergies were included. The subjects first underwent a skin test to confirm food allergies. If candidates were negative, they were excluded. If the result was positive, a propofol skin test was performed., Results: Sixty-four patients with confirmed food allergies underwent a propofol skin test. Only one was positive in the propofol skin test (1.6%). The patient was allergic to peanuts and soybeans. These results reinforce the idea that there is no justification for avoiding propofol use in these subjects., Conclusions: Propofol can be safely administered to patients allergic to soy, eggs, or peanuts. We recommend caution in patients with a history of anaphylaxis after ingestion of the above-mentioned foods.

Modern surgical education is focused on making use of the available technologies in order to train and assess surgical skill acquisition. Innovative technologies for the automatic, objective assessment of nontechnical skills are currently under research. The main aim of this study is to determine whether personal resourcefulness can be assessed by monitoring parameters that are related to stress and visual attention and whether there is a relation between these and psychomotor skills in surgical education. For this purpose, we implemented an application in order to monitor the electrocardiogram (ECG), galvanic skin response (GSR), gaze and performance of surgeons-in-training while performing a laparoscopic box-trainer task so as to obtain technical and personal resourcefulness' metrics. Eight surgeons (6 nonexperts and 2 experts) completed the experiment. A total of 22 metrics were calculated (7 technical and 15 related to personal resourcefulness) per subject. The average values of these metrics in the presence of stressors were compared with those in their absence and depending on the participants' expertise. The results show that both the mean normalized GSR signal and average surgical instrument's acceleration change significantly when stressors are present. Additionally, the GSR and acceleration were found to be correlated, which indicates that there is a relation between psychomotor skills and personal resourcefulness.
