Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)1.

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field

Localização inicial da ponta de cateter central de inserção periférica (PICC) em recém-nascidos Localización inicial de la punta del catéter central de inserción periférica (PICC) en recién nacidos Initial placement of the peripherally inserted central catheter's tip in neonates

Estudo transversal com coleta prospectiva de dados, que objetivouidentificar o posicionamento inicial da ponta do cateter central de inserção periférica (PICC) e verificar a prevalência de sucesso de sua inserção em neonatos. Os dados foram coletados no berçário anexo à maternidade do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, entre março e setembro de 2006. Dos 37 neonatos submetidos à inserção do cateter PICC, a taxa de sucesso no procedimento foi de 72,3% (27 neonatos); destes, quatro (14,8%) estavam com as pontas dos cateteres alojadas nas veias axilar ou inominada; outros três (11,1%), alojadas em veia jugular. Estes cateteres foram removidos por desvio de trajeto. 13 (48,2%) estavam com as pontas alojadas em átrio direito, cujos cateteres foram tracionados para reposicionamento da ponta para a veia cava superior.<br>Estudio transversal con recolección prospectiva de datos. La finalidad fue identificar la posición inicial de la punta del catéter central de inserción periférica (PICC) y verificar la prevalencia de éxitos durante su introducción en neonatos. Los datos fueron recolectados en un servicio de neonatología anexo a la maternidad del Hospital de las Clínicas de la Facultad de Medicina de la Universidad de São Paulo, entre marzo y setiembre del 2006. De los 37 neonatos sometidos a introducción del catéter PICC, la tasa de éxito fue de 72.3% (27 neonatos), de ellos, cuatro (14.8%) estaban con las puntas de los catéteres alojadas en las venas axilar o no determinada, tres (11.1%) localizadas en la vena yugular. Siendo estos últimos retirados por desviación en su trayecto. El 48.2% (13) se encontraba con las puntas en el atrio derecho, siendo estos catéteres nuevamente posicionados en la vena cava superior.<br>This is a cross-sectional study aiming to identify the initial tip position of peripherally inserted central catheters (PICC) and to verify the prevalence of success in inserting such catheters in neonates. The study was carried out in the neonatal care unit of Hospital das Clínicas, Universidade de São Paulo. Data were collected prospectively from March to September 2006. 37 neonates underwent PICC insertion were included in the study. The rate of success for this procedure was 72.3% (27 neonates). Of them, four (14.8%) had the catheter tips placed in the axilary or inominate veins. Three others (11.1%) had them placed in a jugular vein. When these catheters were removed, 13 (48.2%) catheter tip were placed in the right atrium, and they were relocated to the superior vena cava

Input-output analysis of Irish construction sector greenhouse gas emissions

Ireland is committed to limiting its greenhouse gas (GHG) emissions to 113% of 1990 levels over the period 2008–12 and to 84% of 2005 levels by 2020 under the Kyoto Agreement and the EU's 2020 target by 2020 respectively. National policies have targeted many industry sectors but have failed to directly tackle GHG emissions associated with construction activity. This paper estimates energy and GHG emissions intensities of the Irish construction sector and subsectors and estimates its contribution to Irish national emissions. This information is used to identify and assess the impacts of policy measures which would result in a reduction in emissions from the sector in a cost-effective manner. Energy and emissions intensities are estimated using input–output analysis techniques applied to Irish construction sector. In 2005 the Irish construction sector was responsible for the emission of 13.81 mtCO2eq, comprising 2.37 mt (17%) of direct on-site emissions, 5.69 mt (41%) upstream indirect domestic emissions and 5.75 mt (42%) upstream indirect emissions outside the state. Domestically arising direct and indirect emissions accounted for 3.44% and 8.26% of national emissions respectively. Approximately three-quarters of construction sector emissions were the result of activities relating to NACE 45.2 ‘civil and structural construction works, etc’. Given the potential importance of the construction sector to national emissions, there is scope for the implementation of policies which specifically target it. Two such policies are proposed: direct emissions mitigation through a construction EcoDriving initiative; and the provision of information to allow the design and specification of low-emissions materials
