We used transcranial magnetic stimulation (TMS) with a figure-of-eight coil to excite motor and visual V1-V2 cortices in patients suffering from migraine without (MO) (n = 24) or with aura (MA) (n = 13) and in healthy volunteers (HV) (n = 33). Patients who had a migraine attack within 3 days before or after the recordings were excluded. All females were recorded at mid-cycle. Single TMS pulses over the occipital cortex elicited phosphenes in 64% of HV, 63% of MO and 69% of MA patients. Compared with HV, the phosphene threshold was significantly increased in MO (P = 0.001) and in MA (P = 0.007), but there was no difference between the two groups of migraineurs. The motor threshold tended to be higher in both migraine groups than in HV, but the differences were not significant. In conclusion, this study shows that two-thirds (64.86%) of patients affected by either migraine type present an increased phosphene threshold in the interictal period, which suggests that their visual cortex is hypoexcitable.

In most organisms, the main form of thiamine is the coenzyme thiamine diphosphate. Thiamine triphosphate (ThTP) is also found in low amounts in most vertebrate tissues and can phosphorylate certain proteins. Here we show that ThTP exists not only in vertebrates but is present in bacteria, fungi, plants and invertebrates. Unexpectedly, we found that in Escherichia coli as well as in Arabidopsis thaliana, ThTP was synthesized only under particular circumstances such as hypoxia (E. coli) or withering (A. thaliana). In mammalian tissues, ThTP concentrations are regulated by a specific thiamine triphosphatase that we have recently characterized. This enzyme was found only in mammals. In other organisms, ThTP can be hydrolyzed by unspecific phosphohydrolases. The occurrence of ThTP from prokaryotes to mammals suggests that it may have a basic role in cell metabolism or cell signaling. A decreased content may contribute to the symptoms observed during thiamine deficiency. [less ▲]

Our ability to recognise the usual horizontal orientation Of Our own face (mirror orientation) as compared with another very familiar face (normal orientation) was examined in experiment 1. Participants did not use the same kind of information in determining the orientation of their own face as in determining the orientation of the other familiar face. The proportion of participants who reported having based their judgment on the location of an asymmetric feature (eg a mole) was higher when determining the orientation of their own face than when determining that of the other familiar face. In experiment 2, participants were presented with pairs of manipulated images of their own face and of another familiar face showing conflicting asymmetric features and configural information. Each pair consisted of one picture showing asymmetric features of a given face in a mirror-reversed position, while the facial configuration was left unchanged; and one picture in which the location of the asymmetric features was left unchanged, while the facial configuration was mirror-reversed. As expected from the hypothesis that asymmetric local features are more frequently used for the judgment of one's own face, participants chose the picture showing mirror-reversed asymmetric features when determining the usual orientation of their own face significantly more often than they chose the picture showing normally oriented asymmetric features when determining the orientation of the other face. These results are explained in terms of competing forward and mirror-reversed representations of one's own face. [less ▲]

Des diagnostics de gravidité ont été réalisés chez 64 femelles zébus de races Peuhl et Goudali (Bos indicus) aux 28è et 40è jours postinsémination à l'aide d'un échographe muni d'une sonde linéaire de 6 MHz. Au 28è jour, l'exactitude globale a été de 92,2 p. 100, avec une exactitude de 92,6 p. 100 et 91,9 p. 100 respectivement pour les diagnostics positif et négatif. Au 40è jour, l'exactitude globale a été de 98,4 p. 100, avec une exactitude de 100 p. 100 et 97,3 p. 100 respectivement pour les diagnostics positif et négatif. Les fiabilités ont varié de 89,2 p. 100 (fiabilité du diagnostic de gravidité positif au 28è jour) à 100 p. 100 (fiabilité du diagnostic de gravidité négatif au 40è jour). Par ailleurs, la croissance foetale a été suivie chez 16 femelles gravides du 45è au 120è jour postinsémination. Les principales mensurations foetales réalisées ont été les diamètres du crâne et du tronc. Au 45è jour de la gravidité, les diamètres du crâne et du tronc ont été respectivement de 1,8 ± 0,1 cm et 1,4 ± 0,3 cm. Au 120è jour, ces valeurs ont été de 6,5 ± 0,6 cm et 5,8 ± 0,5 cm. A partir du 120è jour, l'utérus a pris une position très profonde, ne permettant plus la visualisation du foetus en croissance. [less ▲]

Because symptoms associated with hypomagnesia are highly aspecific, this ionic abnormality is rarely searched for although it could be present in as much as 20 % of the population. The mode of correction (oral or intravenous) depends on the etiology, severity and clinical consequences of hypomagnesemia. Significant hypermagnesemia only occurs in the presence of renal insufficiency and/or acute excess administration, mainly by the intravenous route. If interruption of administration does not suffice, renal dialysis might become necessary to quickly correct the magnesemium serum levels. [less ▲]

Paedomorphosis is an evolutionary process in which larval structures are retained in adult animals. In newts and salamanders, this heterochronic process is widely represented and concerns the retention of gill slits. Our aim was to find out whether habitat and geographical determinants may be associated with paedomorphosis in a European species of newt. To this end, we determined the main characteristics of the aquatic sites containing paedomorphic Alpine newts that have been described in the literature or discovered by one of us. Although metamorphs are widely distributed in Europe, paedomorphs were only found at the southern margin of the geographic range of the species: mainly in the Italian and Balkan peninsulas. They were recorded in 87 aquatic sites. No single trend was outlined for the analyzed ecological parameters of the aquatic and surrounding terrestrial habitats (e.g. altitude, maximum water depth, drying and presence of forest). These results show that paedomorphs can be found in both favorable aquatic habitats surrounded by hostile terrestrial landscapes, but also in temporary waters located in proximity to appropriate terrestrial environments. Models predicting paedomorphosis in varied environments are thus supported, but require complementary investigations on the costs and benefits of each alternative ontogenetic pathway. On the other hand, the southern limitation of the heterochronic phenomenon and the existence of favorable sites in northern and eastern Europe suggest a genetic basis for paedomorphosis in the studied species.
