An infectious ætiology for multiple sclerosis (MS) has been postulated but none of the agents putatively associated with the disease have, as yet, been proven to be causative.1-4 The reported5 isolation of an infectious agent from bone-marrow aspiration of patients with MS prompted us to attempt recovery of an agent from our MS patients. We were unable to isolate an agent from seven MS patients with similar cell lines and procedures. There is no apparent reason for our inability to do so. However, we did find an adventitious agent(s) in two commercial sources of Hela cells. Although not initially apparent, this agent(s) became active upon incubation with either MS-patient or control bone-marrow cells and induced large syncytia when passed to other Hela cells. [less ▲]

In a porcine liver transplant model, a brief period of oxygenated hypothermic machine perfusion (HMP) at the end of simple cold storage (SCS) has been shown to improve the viability of damaged liver grafts. To test the clinical validity of this strategy, we randomized SCS-discarded human liver grafts to either 4 hours of HMP (n = 13) or an additional 4 hours of SCS (n = 14). All livers were then warm reperfused to mimic ischemia-reperfusion injury ex vivo. The settings for HMP were: portal vein: 3 mm Hg, 300 mL/min and hepatic artery: 20 mm Hg, po(2): 300 mm Hg. Perfusion used Kidney Machine Perfusion Solution at 4 degrees C to 8 degrees C. During warm reperfusion, aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) values were higher (P < .015) among the SCS versus HMP methods at all times. The AST slope was lower in HMP versus SCS (P = .01). The LDH slope tended to be lower for HMP versus SCS (P = .07). Morphological scores were not different between HMP and SCS. At the start of warm reperfusion, MAPK was lower in HMP versus SCS (P = .02). Endothelin-1 (EDN1) and ICAM-1 tended to be lower in HMP versus SCS (P = .1 and .07, respectively). No difference was noted in MAPK, EDN1, and ICAM-1 after 60 or 120 minutes of warm reperfusion. In conclusion, HMP down-regulated MAPK and tended to reduce EDN1 and ICAM-1 mRNA in human liver grafts. During warm reperfusion, HMP versus SCS livers showed reduced AST and LDH release but no morphological difference. Further optimization of liver HMP may require different timing/duration of perfusion and/or an higher perfusion temperature. [less ▲]

With the objective of determining whether it would be possible to sustainably produce Jatropha curcas L. seeds on the marginal land situated close to the Senegal River, a 6-hectare pilot plantation was cultivated under drip irrigation between September 2007-November 2011, close to the village of Bokhol (Lat. 16°31’N, Long. 15°23’W). A series of tests were conducted on this plot, in order to identify the best cultivation methods for the area (date, density and method of planting, appropriate type of pruning, fertilisers to be applied, irrigation method, etc.). The average yields obtained at this site, after four years of cultivation (less than 500 kg.ha-1 of dry seed), using the best known production techniques, are significantly lower than anticipated, compared to the available figures for the irrigated cultivation of Jatropha in other parts of the world. The main causes of this failure are the plant’s limited useful vegetation period of six months per year, instead of twelve, and the scale of attacks by a soilborne vascular disease, which destroyed over 60% of the plantation within four years.

Within the framework of the contract of Sourou River, a survey of the groundwater quality was performed through 7 campaigns of water sampling and analysis from 2006 till 2012. The water samples resulted from 23 drillings and 9 wells located in the Sourou Valley. Among the analyzed physico-chemical parameters, the nitrates concentrations ob- served were worrisome. Out of 32 water sources, 14 (44%) supplied a nitrates content superior to the WHO threshold value for drinking water (50 mg NO3/L). Very high concentrations, superior to 500 mg NO3/L with a peak in 860 mg/L, were observed. Given the important variations observed from a sampling point to another, a generalized contamination of the total aquifer was not possible. An individual diagnosis allowed to identify the possible causes of this degradation. Several sources of contamination, in connection with the anthropological activities, were observed near the water facili- ties (drillings/wells): animal and human wild defecation, presence of nontight latrines, solid waste, wastewater dis- charges. It is also advisable to wonder about the impact of the dynamite use for digging wells, this one being able to leave nitrates in the water. With regard to the intensive use of water from the strongly contaminated wells and drillings by the rural populations of Sourou, implementing protection areas within which would be eliminated the sources of contamination in addition to health education among populations could improve the situation. Care should also be taken in the use of nitrates explosives for digging new wells or drillings. [less ▲]

Over the past twenty-five years, a great deal of evidence has been accumulated indicating that advancing age is accompanied by a systematic decline in performance on a wide variety of cognitive tasks, both in the laboratory and in everyday life. However, age-related decline is not observed in all situations and older adults may even show a relative advantage in some tasks. [less ▲]

A number of neuropsychological studies in recent years have shown that demented patients do not necessarily present a global deterioration and that the disease can impair some cognitive processes or systems, while sparing others. Moreover, qualitatively different patterns of cognitive impairment have been identified in association with different types of neurodegenerative dementias, such as Alzheimer's disease, Huntington's disease, Parkinson's disease or frontotemporal dementia.

Les concepts d'attention et de mémoire de travail ont très souvent été considérés de façon distincte, que ce soit dans le domaine de la recherche ou dans celui de la pratique clinique en neuropsychologie. Or, une analyse détaillée des modèles théoriques de l'attention et de la mémoire de travail indique au contraire qu'il existe un large recouvrement entre ces deux domaines. L'objectif de ce chapitre est de mettre en exergue ces relations et recouvrements. Plus spécifiquement, nous montrerons en quoi la mémoire de travail a une fonction essentielle de contrôle attentionnel de l'action, nous décrirons les études d'imagerie fonctionnelle ayant exploré les bases cérébrales de cette fonction de contrôle attentionnel et nous présenterons enfin quelques travaux ayant mis en évidence une relation spécifique entre mémoire de travail, attention sélective et vigilance.
