From Engels to Adorno and Horkheimer, to Althusser or Bourdieu everything seems to occur as if criticism in its main variation – the Marxist approach – had worked to feed a principal way of thinking: individuals (workers, proletarians, social actors, etc.) unconsciously reproduce the social structures of capitalism which alienate them. They accept the conditions enforced on them and no longer seek to rebel against a world which substantially impoverish their labor, their soul and their creativity. Even worse: they ensure the reproduction of the system by seeking to engage in mass consumption at any price. There is little doubt that Marx was not wrong to point out, with the concept of alienation, the inhuman working conditions in which the nineteenth century proletariat was, and which a huge part of the workers still have to face all around the world nowadays. Should the worker-consumer only be seen as a scatterbrain being who unconsciously reproduces, to use Bourdieu’s language, the conditions of his domination? My intention here is not to put Marx in the dock, since he is, I am sure, an author whose work has remained of unequalled power for over a century. However, I would like to try and show that by dint of favouring almost exclusively the concept of alienation in his work, there is a considerable risk that only a negative path for criticism can emerge from it. It is that initial heart of criticism which was Marx’s thinking and which has irrigated the whole twentieth century from the Frankfurt School to French critical sociology that I would like to put into perspective by suggesting a new agenda for critical research that I would characterize as, for now and for lack of a better term, positive. This agenda of research is in its early days. Nonetheless, in my opinion, a theoretical base should be given to it straight away. The following pages will try to establish it by notably drawing on the main theoretician of libertarian anarchism, Marx’s rival on socialist theory, Proudhon. However, I would like to insist on the fact that the purpose is not to truly turn the latter against Marx . Because I think that Marx must remain a topical issue, I rather wish to demonstrate that, at the cradle of criticism, right next to him, there is an equally – or even more? – Materialist position which could be pertinently combined to the criticism of alienation . This position might be helpful to highlight, here and now, possibilities of emancipation through labor which are not exclusively conditioned by the “Grand Soir”. Proudhon’s work is certainly philosophically and economically weaker than Marx’s. However, Proudhon is very interesting in the way he manages to see in a “laboring” man something else than a slave-laboring animal deprived of subjectivity by capitalism and who only exists as a production tool. In that way, criticism, if any, may be considered as positive [less ▲]

A new set of 725 NO limb profiles has been analyzed. The profiles have been deconvolved and inverted to get volume emission rates. Updates mean VER peak altitude is 115 km, in excellent agreement with PV results obtained 30 years ago. The corresponding average vertical intensity is 1.2 kR. The altitude of emission occurs at a higher altitude near the bright spot region than at larger distances (by about 7 km). The location of the statistical bright spot is the same as observed with PV (that is shifted dawnward by 2 hrs and slightly south of AS point). The nightside mean vertical intensity is between 0.4 and 1.8 kR, which brackets the values derived from the limb profiles. These results, coupled with other airglow measurements, provide constraints on global atmospheric circulation and vertical transport [less ▲]

Various [18F]fluoro aromatic α-methyl-L-amino acids 11 have been synthesized with high enantiomeric purity (ee > 97%). These new radiopharmaceuticals for Positron Emission Tomography (PET), potential inhibitors of enzymatic functions, were regiospecifically labelled by nucleophilic substitution on trimethylammoniumbenzaldehyde triflate precursors 9. The [18F]fluoro aromatic aldehydes 12 obtained were easily converted to the corresponding [18F]fluorobenzyl halides [13 (X = 1)]. After alkylation of the lithium enolate of (2S,5S)-l-tert-Boc-2-tert-butyl-3,5-dimethyl-imidazolidin-4-one 2, the adducts were cleaved to give, after HPLC purification, various [18F]fluoro-α-methyl amino acid analogs with radiochemical yields of 10% (End of Bombardment, EOB) after a synthesis time of 120 min. The corresponding [19F]fluorinated amino acids 4 and [19F]fluoro intermediates were also prepared. [less ▲]

This paper describes the preparation of 6-[18F]fluoro-L-dopa by a no-carrier-added method based on the nucleophilic displacement of nitro groups of two commercially available substrates, 3,4-dimethoxy-2-nitrobenzaldehyde (nitroveratraldehyde) and 6-nitropiperonal. Fluorination was conducted in DMSO with fluorine-18 (18F) in the presence of the aminopolyether Kryptofix 222 and potassium carbonate. The condensation of the fluorinated aldehydes with phenyloxazolone and the subsequent hydrolysis with HI/P yield, after purification by HPLC, only the 6-(D, L) isomers. The racemic mixture (50/50) was resolved on an analytical scale chiral column. The method, which requires 100 min (EOB) to complete, produces 6-[18F]fluoro-L-dopa with a decay-corrected radiochemical yield of 10%, an enantiomeric purity greater than 99%, and a specific activity of 1.2 Ci/mumole.

BACKGROUND: . The Nociception Coma Scale-Revised (NCS-R) was recently validated to assess possible pain perception in patients with disorders of consciousness. OBJECTIVE: . To identify correlations between cerebral glucose metabolism and NCS-R total scores. METHODS: . [18F]-fluorodeoxyglucose positron emission tomography, NCS-R, and Coma Recovery Scale-Revised assessments were performed in 49 patients with disorders of consciousness. RESULTS: . We identified a significant positive correlation between NCS-R total scores and metabolism in the posterior part of the anterior cingulate cortex, known to be involved in pain processing. No other cluster reached significance. No significant effect of clinical diagnosis (vegetative/unresponsive vs minimally conscious states), etiology or interval since insult was observed. CONCLUSIONS: . Our data support the hypothesis that the NCS-R total scores are related to cortical processing of nociception and may constitute an appropriate behavioral tool to assess, monitor, and treat possible pain in brain-damaged noncommunicative patients with disorders of consciousness. Future studies using event-related functional magnetic resonance imaging should investigate the correlation between NCS-R scores and brain activation in response to noxious stimulation at the single-subject level.

Assessing behavioral responses to nociception is difficult in severely brain-injured patients recovering from coma. We here propose a new scale developed for assessing nociception in vegetative (VS) and minimally conscious (MCS) coma survivors, the Nociception Coma Scale (NCS), and explore its concurrent validity, inter-rater agreement and sensitivity. Concurrent validity was assessed by analyzing behavioral responses of 48 post-comatose patients to a noxious stimulation (pressure applied to the fingernail) (28 VS and 20 MCS; age range 20-82years; 17 of traumatic etiology). Patients' were assessed using the NCS and four other scales employed in non-communicative patients: the 'Neonatal Infant Pain Scale' (NIPS) and the 'Faces, Legs, Activity, Cry, Consolability' (FLACC) used in newborns; and the 'Pain Assessment In Advanced Dementia Scale' (PAINAD) and the 'Checklist of Non-verbal Pain Indicators' (CNPI) used in dementia. For the establishment of inter-rater agreement, fifteen patients were concurrently assessed by two examiners. Concurrent validity, assessed by Spearman rank order correlations between the NCS and the four other validated scales, was good. Cohen's kappa analyses revealed a good to excellent inter-rater agreement for the NCS total and subscore measures, indicating that the scale yields reproducible findings across examiners. Finally, a significant difference between NCS total scores was observed as a function of diagnosis (i.e., VS or MCS). The NCS constitutes a sensitive clinical tool for assessing nociception in severely brain-injured patients. This scale constitutes the first step to a better management of patients recovering from coma. [less ▲]

BACKGROUND: Lack of habituation, as reported in migraine patients between attacks for evoked cortical responses, was also recently found for the nociceptive blink reflex (nBR) mediated by brainstem neurons. It is not known if both brain stem and cortical habituation deficits are correlated in the same patient, which would favor a common underlying mechanism. OBJECTIVE: To search for intraindividual correlations between habituation of pattern reversal-visual evoked potentials and that of the nociception-specific blink reflex in migraineurs and in healthy volunteers (HV). METHODS: We recorded 15 HV and 15 migraine without aura patients between attacks. Habituation for visual evoked potentials was measured by comparing the N1-P1 amplitude change (%) between the first and sixth block of 100 sequential averaged responses. Habituation for the nBR was defined as the percentage change of the R2 response area between the 1st and 10th block of five averaged EMG responses, elicited by stimulating the right side every 2 minutes for 32 minutes. We also calculated the slope of N1-P1 amplitude and R2 response area changes from the first to the last response and the correlation with attack frequency. RESULTS: A significant habituation deficit in both cortical and brain stem evoked activity characterized on average the group of migraineurs compared to controls. In migraine patients, but not in HV, we found a significant positive correlation between habituation of pattern reversal-visual evoked potentials and that of the nociception-specific blink reflex both for the degree of habituation between first and last blocks of averagings (r = 0.703; P = .003) and for the habituation slope (r = 0.751; P = .001). Moreover, nBR habituation was positively correlated with attack frequency (r = 0.548; P = .034). CONCLUSION: The positive correlation between visual evoked potential and nBR habituations is consistent with the idea that in migraine the same neurobiological dysfunction might be responsible for the habituation deficit both in cortex and brain stem. As nBR habituation increases with attack frequency, its interictal deficit is unlikely to be due to trigeminal sensitization. [less ▲]
