This study explores the potential cultivation of the giant kelp Macrocystis pyrifera (L.) C.A. Agardh in southern Chile, for the development of novel food products. The study demonstrates the importance of considering the collection site of the parent sporophytes for successful cultivation. This study also shows that the ropes must be seeded with 10,000 to(More)
BACKGROUND AND OBJECTIVES Radio frequency identification (RFID) can be a key enabler for enhancing productivity and safety of the blood product supply chain. This article describes a systematic approach developed by the RFID Blood Consortium for a comprehensive feasibility and impact assessment of RFID application in blood centre operations. MATERIALS AND(More)
OBJECTIVE To investigate the relationship between neurological complications, neuroradiological findings, and behavioral problems, age at diagnosis and dietary control along the follow-up of the PKU patients in our metabolic unit. DESIGN Retrospective study of the PKU patients diagnosed and controlled in our unit from 1985 to 2010. METHODS Registry of(More)
Radio frequency identification (RFID) is a rapidly evolving technology for automatic identification and data capture of products. One of the barriers to the adoption of RFID by organizations is difficulty in assessing the potential return on investment (ROI). Much of the research and analyses to date of ROI in implementing RFID technology have focused on(More)
ISO/IEC 18000-3 mode 1 standard 13.56 MHz RFID tags have been accepted by the International Society for Blood Transfusion (ISBT) and the United States Food and Drug Administration (FDA) as data carriers to integrate with and augment ISBT 128 barcode data carried on blood products. The use of 13.56 MHz RFID carrying ISBT 128 data structures allows the global(More)
As part of an overall design of a new, standardized RFID-enabled blood transfusion medicine supply chain, an assessment was conducted for two hospitals: the University of Iowa Hospital and Clinics (UIHC) and Mississippi Baptist Health System (MBHS). The main objectives of the study were to assess RFID technological and economic feasibility, along with(More)
The purpose of this study was to determine clinical variables influence (comorbid medical condition, functional independence, depressive and neuropsychiatric symptoms) on the performance of the TUG, taking into account the level of cognitive impairment in elderly institutionalized people. A cross-sectional analysis of 405 sedentary older adults living in(More)
Abalone aquaculture is rapidly developing in Chile although this mollusc does not occur naturally in this country. The red abalone Haliotis rufescens was introduced in 1977 and the ezo abalone Haliotis discus hannai in 1982. After several years of research and development, the industry began in 1992 and Chile is currently the fifth producer of cultured(More)
The purpose of this study is to provide a tool, based on the knowledge of technical errors, which helps to improve the teaching and learning process of the Uki Goshi technique. With this aim, we set out to determine the most frequent errors made by 44 students when performing this technique and how these mistakes relate. In order to do so, an observational(More)
BACKGROUND AND OBJECTIVE To evaluate the management of phenylketonuria (PKU) in Spanish metabolic units and to develop a patients registry. PATIENTS AND METHODS PKU patients diagnosed and/or followed up in Spain, with phenylalanine values before treatment > 360 μmol/L. Registered anonymous data are those yielded by the units during 2010. RESULTS Data(More)
