    Essential versus accessory aspects of cell death: recommendations of the NCCD 2015

    Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ‘accidental cell death’ (ACD). In most settings, however, cell death is initiated by a genetically encoded apparatus, correlating with the fact that its course can be altered by pharmacologic or genetic interventions. ‘Regulated cell death’ (RCD) can occur as part of physiologic programs or can be activated once adaptive responses to perturbations of the extracellular or intracellular microenvironment fail. The biochemical phenomena that accompany RCD may be harnessed to classify it into a few subtypes, which often (but not always) exhibit stereotyped morphologic features. Nonetheless, efficiently inhibiting the processes that are commonly thought to cause RCD, such as the activation of executioner caspases in the course of apoptosis, does not exert true cytoprotective effects in the mammalian system, but simply alters the kinetics of cellular demise as it shifts its morphologic and biochemical correlates. Conversely, bona fide cytoprotection can be achieved by inhibiting the transduction of lethal signals in the early phases of the process, when adaptive responses are still operational. Thus, the mechanisms that truly execute RCD may be less understood, less inhibitable and perhaps more homogeneous than previously thought. Here, the Nomenclature Committee on Cell Death formulates a set of recommendations to help scientists and researchers to discriminate between essential and accessory aspects of cell death

    The implications of fedralism and decentralisation in socio-economic conditions in Ethiopia

    This paper analyses impacts of the federal system and the decentralisation of functions to the district level on Ethiopia's socio-economic development. Firstly we will highlight the principles of the Ethiopian federal system as well as those of the 2001/2002 decentralisation process. Secondly we will show how the decentralisation has impacted on two of the decentralised sectors, health and education, by comparing pre-federal, pre- and post-decentralisation data. In both cases an overall increase in allocated budgets and an increase in the scale of the services offered since decentralisation started in 2001 has been found. Studies also show that the increase in services is not homogenous across regional states. Within the four larger regions, strongly disadvantaged woredas at the outset of the decentralisation process have profited most, which shows that the constitutional imperative of equal access to services is being implemented. Some of the regions where decentralisation was started later have still not caught up with the other regions, a phenomenon which is mostly due to capacity deficits. The article concludes that decentralisation in combination with consistent development policies has led to an overall improvement in service delivery, while some challenges regarding quality and equity still need to be addressed
