Le grec ancien dispose d’au moins quatre manières d’exprimer la négation adverbiale temporelle «ne...jamais»: οὐ...ποτέ, οὐ...πώποτε (en un seul mot ou en deux mots), οὐδέποτε et οὐδεπώποτε. En nous appuyant sur un corpus de prose oratoire classique (Lysias et Démosthène), nous tentons de rendre compte de l’emploi d’une série en πώποτε (souvent traduite par «ne...jamais encore») à côté d’une série en ποτέ. Pour ce faire, nous mettons en évidence des différences de plusieurs sortes entre les deux séries. Il existe en effet des différences syntaxiques, puisque πώποτε est un terme à polarité négative, tout comme πώ qui entre dans sa formation, et des différences sémantiques, particulièrement aspectuelles et modales, liées au sens de πώ (habituellement traduit par «ne...pas encore»). Avec la série en πώποτε, sur le plan aspectuel, le procès négatif est susceptible de devenir positif au-delà d’un moment de référence défini dans le discours, et sur le plan modal, ce procès négatif s’oppose à un procès positif auquel on aurait pu s’attendre. La particularité du grec ancien provient des cas où l’indéfini πώ, terme à polarité négative, impose une lecture de πώποτε comme un indéfini de libre choix («jamais, à quelque moment que ce soit») et non comme un adverbe de phase («jamais encore»).

The knowledge of the anatomy of the atria and interatrial septum permits different routes to approach the left atrioventricular valve. The Waterston's or Sondegaard's groove approach is the most frequently used, but other approaches such as Dubost'transseptal technique, vertical transseptal approach (Berreklouw-Guiraudon), biatrial inferior transseptal approach (Couetil) or Saksena's approach may be relevant in special situations. It is the purpose of this article to review the anatomic and technical basis of these different approaches and their respective merits. [less ▲]

Ischaemic injury leads to the expression of heat shock and immediate early genes. Here the localization of this induction is examined by in situ hybridization analysis in serial sections of buffer-perfused isolated rat heart after 30 min of coronary artery occlusion. The accumulation of mRNA for hsc70, hsp70, c-fos, c-jun, and Erg-1 was localized coincidently and was restricted to the ischaemic area of the heart. mRNA for these genes was undetectable at the end of the ischaemic period (no reperfusion). After 30 min of reperfusion, accumulation of mRNA for hsc70, hsp70, c-fos, and c-jun was detectable and increased with further reperfusion. Within the area labelled for these gene products was a central area of less intense labelling which corresponded to the necrotic zone. The immediate early gene product, jun-B, was localized in both the ischaemic and the non-ischaemic area of the hearts. These results suggest that the area of the heart where heat shock and immediate early gene transcripts accumulate, while injured, recovers transcriptional activity, and that the central area where minimal heat shock and immediate early gene transcripts accumulate, does not recover transcriptional activity and is irreversibly injured.

A promising way to oppose infectious challenges would be to improve the resistance of the target species through genetic selection. Theoretically, a candidate gene is available against influenza viruses since a resistance trait was fortuitously discovered in the A2G mouse strain. This trait was demonstrated to be correlated with the expression of a specific isoform of the type I interferon (IFN)-dependent protein MX, an isoform coded by a specific allele at the mouse Mx1 locus. Two allelic polymorphisms were described recently in the Sus scrofa homologous gene. In this study, the frequencies and distribution of both alleles were evaluated among European domestic pig and wild boar populations by PCR-RFLP, and the anti-influenza activity conferred by both MX1 isoforms was evaluated in vitro using transfection of Vero cells followed by flow cytometric determination of the fraction of influenza virus-infected cells among MX-producing and MX-nonproducing cell populations. A significant difference in the anti-influenza activity brought by the two MX1 isoforms was demonstrated, which suggests that a significant improvement of innate resistance of pigs by genetic selection might be feasible provided the differences found here in vitro are epidemiologically relevant in vivo.

Context. The CoRoT short asteroseismic runs give us the opportunity to observe a large variety of late-type stars through their solar-like oscillations. We report the observation and modeling of the F5V star HD 175272. <BR /> Aims: Our aim is to define a method for extracting as much information as possible from a noisy oscillation spectrum. <BR /> Methods: We followed a differential approach that consists of using a well-known star as a reference to characterize another star. We used classical tools such as the envelope autocorrelation function to derive the global seismic parameters of the star. We compared HD 175272 with HD 181420 through a linear approach, because they appear to be asteroseismic twins. <BR /> Results: The comparison with the reference star enables us to substantially enhance the scientific output for HD 175272. First, we determined its global characteristics through a detailed seismic analysis of HD 181420. Second, with our differential approach, we measured the difference of mass, radius and age between HD 175272 and HD 181420. <BR /> Conclusions: We have developed a general method able to derive asteroseismic constraints on a star even in case of low-quality data. This method can be applied to stars with interesting properties but low signal-to-noise ratio oscillation spectrum, such as stars hosting an exoplanet or members of a binary system. The CoRoT space mission, launched on 2006 December 27, was developed and is operated by the CNES, with participation of the Science Programs of ESA, ESAs RSSD, Austria, Belgium, Brazil, Germany and Spain.

We investigated the effects of presenting a sexual conditioned stimulus on the expression of c-fos in male Japanese quail. Eight brain sites were selected for analysis based on previous reports of c-fos expression in these areas correlated with sexual behaviour or learning. Males received either paired or explicitly unpaired presentations of an arbitrary stimulus and visual access to a female. Nine conditioning trials were conducted, one per day, for each subject. On the day following the ninth trial, subjects were exposed to the conditional stimulus (CS) for 5 min. Conditioning was confirmed by analysis of rhythmic cloacal sphincter movements (RCSM), an appetitive sexual behaviour, made in response to the CS presentation. Subjects in the paired condition performed significantly more RCSM than subjects in the unpaired group. Brains were collected 90 min following the stimulus exposure and stained by immunolhistochemistry for the FOS protein. Significant group differences in the number of FOS-immunoreactive (FOS-ir) cells were found in two brain regions, the nucleus taeniae of the amygdala (TnA) and the hippocampus (Hp). Subjects in the paired condition had fewer FOS-ir cells in both areas than subjects in the unpaired condition. These data provide additional support to the hypothesis that TnA is implicated in the expression of appetitive sexual behaviours in male quail and corroborate numerous previous reports of the involvement of the hippocampus in conditioning. Further, these data suggest that conditioned and unconditioned sexual stimuli activate different brain regions but have similar behavioural consequences. [less ▲]

Cadmium and zinc share many similar physiochemical properties, but their compartmentation, complexation and impact on other mineral element distribution in plant tissues may drastically differ. In this study, we address the impact of 10-μM Cd or 50-μM Zn treatment on ion distribution in leaves of a metallicolous population of the non-hyperaccumulating species Zygophyllum fabago at tissue and cell level, and the consequences on the plant response through a combined physiological, proteomic and metabolite approach. Micro-proton induced X-ray emission and laser ablation inductively coupled mass spectrometry analyses indicated hot spots of Cd concentrations in the vicinity of vascular bundles in response to Cd treatment, essentially bound to S-containing compounds as revealed by extended X-Ray absorption fine structure and non-protein thiol compounds analyses. A preferential accumulation of Zn occurred in vascular bundle and spongy mesophyll in response to Zn treatment, and was mainly bound to O/N-ligands. Leaf proteomics and physiological status evidenced a protection of photosynthetically active tissues and the maintenance of cell turgor through specific distribution and complexation of toxic ions, reallocation of some essential elements, synthesis of proteins involved in photosynthetic apparatus or C-metabolism, and metabolite synthesis, with some specificities regarding the considered heavy metal treatment.

PET studies have demonstrated bilateral temporo-parietal hypoperfusion and hypometabolism in probable and definite Alzheimer's disease (AD), a pattern that may help differentiate AD from other dementias. METHODS: To evaluate the diagnostic power of cerebral metabolic distribution patterns for "cortical" degenerative dementias, PET scans obtained from 129 patients referred for differential diagnosis of dementia were analyzed visually. RESULTS: Sixty-five patients had a final clinical diagnosis of probable AD. Ninety-seven percent (97%) of those had abnormal metabolic scans and 94% showed a suggestive pattern of bilateral or unilateral temporo-parietal hypometabolism (with or without frontal involvement). Hypometabolism was unilateral in 23% of patients. Five subjects with a neuropathologically proven diagnosis of Alzheimer's disease had a suggestive metabolic pattern. One of those was an early case with frontal hypometabolism exceeding temporo-parietal involvement. Two patients with Alzheimer's-type dementia had isolated bilateral frontal hypometabolism. CONCLUSIONS: This alternative metabolic pattern may correspond to a non-Alzheimer pathology occurring in 10%-20% of patients suffering from clinically probable Alzheimer's disease. Most of the patients with possible but atypical Alzheimer's-type dementia showed isolated bilateral frontal involvement. This metabolic pattern probably corresponds to different diseases, such as Pick's disease, frontal lobe dementia or progressive subcortical gliosis. [less ▲]
