UN involvement and civil war peace agreement implementation

Many studies argue that third-party guarantees, such as those of the United Nations, increase the chances that belligerents will sign peace agreements, but it is unclear how third-party involvement affects the implementation of such agreements. We unpack the relationship between UN involvement and peace agreement success by focusing on the risk of defections during the peace accord implementation phase. We argue that two types of commitment problems, namely involuntary and voluntary defections, emerge from the characteristics of the peace process itself as well as from new opportunities available to rebel groups. We expect that shifts in relative power and polarized voting lead to lower implementation scores overall, but that the deployment of UN troops has a mitigating effect, thereby increasing the prospects of sustainable peace agreements. Using data from the Peace Accords Matrix Implementation Dataset from 1989 to 2010 and personnel commitments to UN peacekeeping operations, we find evidence that large UN missions are better placed to support the implementation and longevity of the peace process.

     

Apoptotic and necrotic brain lesions in a fatal case of carbon monoxide poisoning

A 41-year-old man was accidentally exposed to carbon monoxide (CO) gas and found in a state of cardiopulmonary arrest while he took bath. After admission, he was resuscitated and underwent artificial ventilation in a comatose state and died about 19h later. Computed tomography (CT) examination disclosed bilateral low density area in the basal ganglia and the thalamus, a well-known finding in the CO intoxication. Necropsy, histological examination, DNA ladder assay gave the first line of evidence for the presence of apoptosis as well as necrosis in the human case of CO intoxication. TdT-mediated dUTP-biotin nick-end labeling (TUNEL) positive apoptotic cells were more predominant in the CA2 area than in CA1 area. There is general co-relation between the ratio of TUNEL-positive cells and the DNA laddering on the agarose gel. Basal ganglia and thalamus, which showed bilateral low density area in CT, were revealed to be severe edema. The two types of cell death occurred in the cortex, basal ganglia, hippocampus, thalamus, and cerebellum. Hypoxia caused by CO-hemoglobin formation alone cannot explain the phenomena.
