OBJECTIVES To describe the phenotype of Leber congenital amaurosis (LCA) in 26 probands with mutations in aryl hydrocarbon receptor interacting protein-like 1 protein (AIPL1) and compare it with phenotypes of other LCA-related genes. To describe the electroretinogram (ERG) in heterozygote carriers. METHODS Patients with AIPL1-related LCA were identified in a cohort of 303 patients with LCA by...
OBJECTIVES To identify the risk factors for mortality and establish improved treatment strategies in patients who have acute type A aortic dissection with coronary artery dissection. METHODS From January 1994 through December 2011, we performed surgery in 516 patients with acute type A aortic dissection. We studied 75 (15%) of these patients who had coronary artery dissection. Myocardial isch...
This article presents a study of Life Cycle Assessment (LCA) at a slaughterhouse located in northwestern Mexico with the purpose of testing the premise of a low degree of institutionalization of Industrial Ecology in Mexico. The article aims at analyzing the current role played by the Mexican academia in increasing the degree of institutionalization of the concept of LCA in northwestern Mexico....
PURPOSE Bioenergy is increasingly used to help meet greenhouse gas (GHG) and renewable energy targets. However, bioenergy's sustainability has been questioned, resulting in increasing use of life cycle assessment (LCA). Bioenergy systems are global and complex, and market forces can result in significant changes, relevant to LCA and policy. The goal of this paper is to illustrate the complexiti...
The paper summarises the main results gathered from two extensive applications of Life Cycle Assessment (LCA) to the integrated municipal solid waste management systems of Torino and Cuneo Districts in northern Italy. Scenarios with substantial differences in terms of amount of waste, percentage of SC and strategies for the disposal of residual waste are used in order to discuss on strategies t...
Life cycle assessment (LCA) applications within large European firms are discussed. Many industrial applications have been proposed for cradle to grave assessments of environmental burdens of products, including technology design and optimization, technology strategy, green marketing and environmental foresight. There is evidence of a growth of LCA competences and applications within industrial...
Last lecture we defined the Least Common Ancestor (LCA) and Range Min Query (RMQ) problems. Recall that an LCA query asks for the deepest node in a given rooted tree which is an ancestor of each of two query nodes, while an RMQ query asks for the minimal value stored in some contiguous subarray of a given array. We showed last lecture that an LCA query is nothing more than an RMQ query on an Eu...
Life cycle assessment (LCA) has become the prevalent approach for quantifying the environmental impact of products over their entire life cycle. Unfortunately, LCA studies require large amounts of data that are difficult to collect in practice, which makes them expensive and time consuming. This work introduces a method that simplifies standard LCA studies by using proxy metrics that are identi...
LCA is a suitable method to assess the environmental performance of nanotechnology-based products, although challenges remain due to uncertainties and data gaps. LEITAT participates in different European projects, such as NANOMICEX, NANOPOLYTOX, NEXTEC, EUROTAPES and NANOSOLUTIONS, which contribute in filling in these gaps. Selected representative nanotechnology-based products were modelled, in...
Littoral cell angioma (LCA) is a rare primary splenic vascular tumor, originating from the littoral cells lining the red pulp sinuses of the spleen. There are only a handful of case reports of LCA in children to be found in the literature. We performed a retrospective analysis of the medical charts of pediatric patients with splenic lesions who were treated between 2005 and 2010 in the Pediatri...
