Abstract
BACKGROUND AND PURPOSE In addition to combined central and peripheral demyelination, other immune diseases could involve both the central nervous system (CNS) and peripheral nervous system (PNS). METHODS To identify immune-mediated diseases responsible for symptomatic combined central/peripheral nervous system involvement (ICCPs), we conducted a multicentric retrospective study and assessed clinical, electrophysiological, and radiological features of patients fulfilling our ICCP criteria. RESULTS Thirty patients (20 males) were included and followed during a median of 79.5 months (interquartile range [IQR] = 43-145). The median age at onset was 51.5 years (IQR = 39-58). Patients were assigned to one of four groups: (i) monophasic disease with concomitant CNS/PNS involvement including anti-GQ1b syndrome (acute polyradiculoneuropathy + rhombencephalitis, n = 2), checkpoint inhibitor-related toxicities (acute polyradiculoneuropathy + encephalitis, n = 3), and anti-glial fibrillary acidic protein astrocytopathy (subacute polyradiculoneuropathy and meningoencephalomyelitis with linear gadolinium enhancements, n = 2); (ii) chronic course with concomitant CNS/PNS involvement including paraneoplastic syndromes (ganglionopathy/peripheral hyperexcitability + limbic encephalitis, n = 4); (iii) chronic course with sequential CNS/PNS involvement including POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) syndrome (polyradiculoneuropathy + strokes, n = 2), histiocytosis (polyradiculoneuropathy + lepto-/pachymeningitis, n = 1), and systemic vasculitis (multineuropathy + CNS vasculitis/pachymeningitis, n = 2); and (iv) chronic course with concomitant or sequential CNS/PNS involvement including combined central and peripheral demyelination (polyradiculoneuropathy + CNS demyelinating lesions, n = 10) and connective tissue diseases (ganglionopathy/radiculopathy/multineuropathy + limbic encephalitis/transverse myelitis/stroke, n = 4). CONCLUSIONS We diagnosed nine ICCPs. The timing of central and peripheral manifestations and the disease course help determine the underlying immune disease. When antibody against neuroglial antigen is identified, CNS and PNS involvement is systematically concomitant, suggesting a common CNS/PNS antigen and a simultaneous disruption of blood-nerve and blood-brain barriers.

Abstract
Abstract
Background
While maximal safe resection is the first therapeutic option in patients with newly-diagnosed diffuse low-grade glioma (DLGG), the timing and choice of further treatments (chemotherapy, radiation therapy or combinations of both) remain controversial. Because the expected survival is long in these young patients, the oncological impact of treatments must be balanced with the possible side effects, in particular regarding neurocognitive functioning and quality of life (QoL). Temozolomide (TMZ), an alkylating agent, is widely used in this setting. Here we aimed at evaluating the feasibility of a longitudinal neurocognitive and QoL assessment in DLGG patients receiving TMZ.
Material and Methods
We conducted a prospective study including adult DLGG patients receiving TMZ as first-line treatment after surgical resection(s) or biopsy. Neurocognition and QoL were evaluated longitudinally until progression. The feasibility was evaluated in terms of participation and compliance of a complete neurocognitive and QoL assessment (defined as the completion of these assessments at baseline, 6 months and 12 months). Secondary objectives were the description of the proportion of patients with changes in neurocognitive or QoL scores on TMZ.
Results
Of 29 eligible patients, 26 accepted to enter the study (participation rate 86.7%): 57.7% men, median age 45y. Tumor type was distributed as follows: astrocytoma, IDH-mutant 13/26, astrocytoma, IDH wild-type 1/26 and oligodendroglioma, IDH mutant and 1p19q codeleted 12/26. The compliance rate was 95.6% (evaluable in 23 patients as 3 patients had tumor progression within the first 12 months of TMZ). After TMZ, 13.6% of patients experienced a decline of the MoCA score as compared to baseline (from normal to abnormal). Cognitive complaints according to the FACT-COG assessment were stable for 90.9%. The complete cognitive and QoL evaluations (baseline and after 12 months of TMZ) will be presented.
Conclusion
Our data shows that a longitudinal evaluation of cognition and QoL is feasible in low-grade glioma patients. It suggests that first-line TMZ does not negatively affect neurocognition and QoL. These results must be evaluated in the long-term setting (evaluations ongoing) and confirmed in a larger, multicenter cohort.

Abstract
1.The objectives were to quantify the presence of neurogenic inflammation in 4 regions of the upper digestive tract of anaesthetised ducks (post-pharynx, pseudo-crop, transition between the pseudo-crop and the proventriculus, and proventriculus) after application of HCl stimulation of up to 4 M in the pseudo-crop. 2.The second objective was to quantify the presence of neurogenic inflammation in the same digestive tract regions as mentioned above during 4 feeding periods of foie gras production (rearing, preparation to force-feeding, and second and last meals of the force-feeding period). 3. Extravasation increased above a HCl stimulation threshold of 2 M. Furthermore, more extravasation was observed in the proventriculus compared to the other regions (P < 0·001). 4.Highest extravasation responses were observed in the proventriculus and the pseudo-crop at the end of the preparation period, and in the proventriculus after the second forced meal, compared with the rearing period (P < 0·01), with a return to rearing level at the end of force-feeding. 5.Such a kinetic could be indicative of a relative mildness of the irritant components associated with this feeding practice.

Abstract
In case of accidental release of radionuclides into the environment, actinides represent a severe health risk to human beings following internal contamination (inhalation, ingestion or wound). For a better understanding of the actinide behaviour in man (in term of metabolism, retention, excretion) and in specific biological systems (organs, cells or biochemical pathways), it is of prime importance to have a good knowledge of the relevant actinide solution chemistry and biochemistry, in particular of the thermodynamic constants needed for computing actinide speciation. To a large extent, speciation governs bioavailability and toxicity of elements and has a significant impact on the mechanisms by which toxics accumulate in cell compartments and organs and by which elements are transferred and transported from cell to cell. From another viewpoint, speciation is the prerequisite for the design and success of potential decorporation therapies. The purpose of this review is to present the state of the art of actinide knowledge within biological media. It is also to discuss how actinide speciation can be determined or predicted and to highlight the areas where information is lacking with the aim to encourage new research efforts.

Abstract
A cDNA clone At.MAMI (Arabidopsis thaliana membrane-associated mannitol-induced) was isolated from an Arabidopsis cDNA expression library by immunoselection. The cDNA was full-length (1.18 kb) with an open reading frame of 798 nucleotides encoding a 265 amino acid protein. The sequence of At.MAMI did not show any significant identity with other genes, as well as the deduced amino acid sequence with other proteins. However, prediction methods for the secondary structure of MAMI-30, together with homologous domains revealed some identity with VAP-33, a protein involved in membrane trafficking in neuronal tissues. In contrast to VAP-33, MAMI-30 did not exhibit a transmembrane domain, but positively charged loop regions could be involved in membrane anchoring. Indeed, MAMI-30 was immunodetected in purified plasma membrane from Arabidopsis cells. The gene was responsive to low turgor in Arabidopsis and its expression regulated developmentally. In addition, reduction of turgor caused a higher accumulation of mRNAs.
