Autophagy in neuroinflammation after traumatic brain injury

Neural Regeneration Research 2024年第5期19卷 951-952页

作者： Chinmoy Sarkar marta M.Lipinski Shock Trauma and Anesthesiology Research(STAR)CenterDepartment of AnesthesiologyUniversity of Maryland School of MedicineBaltimoreMDUSA Department of Anatomy and Neurobiology University of Maryland School of MedicineBaltimoreMDUSA

Traumatic brain injury(TBI)is an acquired injury of the brain caused by the impact of external forces on the brain(Maas et al.,2008).It is a major cause of death and disability among people of all ages(Maas et al.,2008).The primary mechanical injury to the brain initiates a cascade of secondary biochemical events that lead to acute and chronic neurodegeneration and activation of inflammatory pathways(Maas et al.,2008).Both brain-resident microglia and blood-derived myeloid cells-macrophages and monocytes that infiltrate the brain due to injury-induced blood-brain barrier damage,contribute to the inflammatory responses after TBI(Morganti et al.,2015).

This article has the general objective of estimating the efficiency of urban solid waste management in 940 Brazilian munici-palities through Data Envelopment Analysis(DEA)technique and has specific objectives:(i)to estimate efficiency scores;(ii)to compare the performance between different groups of municipalities;and(ii)to analyze the profile of efficient munici-palities from the perspective of the guidelines of Law 12,305/2010 and socio-economic and environmental *** technique used was DEA with output-oriented and variable scale to return *** results showed higher efficiency scores in the municipalities with populations above 500,000 *** score variation ranged from 0.5(municipalities with populations<10,000 inhabitants)to 0.9(municipalities with more than 500,000 inhabitants).Of the sample set,only 12.34%of the municipalities were considered efficient,and when analyzing the efficient group,it was found that adherence to legislation was not a major factor in achieving efficiency.
