The flash photolysis technique was employed to study the properties of eosin triplet state in aqueous micellar solutions. Increasing the concentration of cetyltrimethylammonium bromide from 10−6 M to the CMC leads to a dramatic decrease of triplet absorbance and to the appearance of a very fast decay process of triplet state resulting from the formation of dye-rich induced micelles. From the CMC to 10−2 M, the absorbance and the lifetime of triplet state increase progressively. [less ▲]

The linear chromatic aberration (LCA) of several combinations of polycarbonates (PCs) and poly (methyl methacrylates) (PMMAs) as singlet, hybrid (refractive/diffractive) lenses and doublets operating with wavelengths between 380 and 1600 nm – corresponding to a typical zone of interest of concentrated photovoltaics (CPV) – are compared. Those comparisons show that the maximum theoretical concentration factor for singlets is limited to about 1000 × at normal incidence and that hybrid lenses and refractive doublets present a smaller LCA increasing the concentration factor up to 5000 × and 2 × 106 respectively. A new achromatization equation more useful than the Abbé equation is also presented. Finally we determined the ideal position of the focal point as a function of the LCA and the geometric concentration which maximizes the flux on the solar cell. [less ▲]

In many plants, flowering is promoted by a long exposure to cold, a process known as ‘vernalisation’. In Arabidopsis, the vernalisation pathway was shown to promote flowering via the repression of the FLOWERING LOCUS C (FLC) gene, which encodes a repressor of flowering. As far as we know, the genetical control of flowering is conserved among Brassicaceae, and we reported elsewhere cloning of flowering times genes of the photoperiodic pathway in Sinapis alba, based on sequence similarity with Arabidopsis. However, little is known about vernalisation in Sinapis. We therefore undertook a physiological and molecular study of this process. Plants of Sinapis were grown in non inductive short days and vernalised at 7°C, at the seedling stage. Vernalisation was found to accelerate flowering and an increasing effect was observed for vernalisation treatments longer than 2 weeks. We cloned an FLC-like sequence (SaFLC) by screening a cDNA library, and used it as a probe to perform expression analyses. We observed that SaFLC was almost completely repressed after 1 week of vernalisation, but repression was stable only after 2 weeks, which is consistent with the fact that 2-week is the minimal duration of vernalisation that promotes flowering. Hence the molecular mechanisms of vernalisation seem to be conserved in Sinapis and Arabidopsis. [less ▲]

Vernalization is known to promote flowering in Arabidopsis via the repression by cold of the floral inhibitor gene FLOWERING LOCUS C (FLC). For long, FLC homologs have been found in Brassicaceae only but it was recently reported that in sugar beet, the FLC-like gene BvFL1 functions as a repressor of flowering and is downregulated in response to cold. We describe here the cloning of CiFL1 from root chicory (Cichorium intybus). Expression patterns were studied in two cultivars, differing in their sensitivity to vernalization. Transcript level analyzes were performed during the vernalization treatment of the seedlings and in different post-vernalization conditions. Our results give further support to conservation of the biological function of FLC-like genes in eudicot species. [less ▲]

The prevailing neurochemical theory about biological correlates of suicidal behavior focuses on the serotonergic system. In this study, we assessed the cortisol, ACTH, GH, prolactin and temperature responses to flesinoxan, a5-HT1A agonist, in 30 DSM-III-R major depressed inpatients subgrouped into suicide attempters (n = 15) and nonattempters (n = 15). The patients were assessed after a drug-free period of at least 3 weeks. A subsample of 16 patients completed the Buss-Durkee Hostility Inventory as a measure of impulsive aggressive behavior. Mean delta cortisol responses to flesinoxan were significantly lower in the group of depressed patients with a history of suicide attempts than in the group without history of suicidal behavior: for the delta cortisol values 14.5 +/- 16.3 micrograms/l vs 101 +/- 94 micrograms/l (F = 8.9, df = 5.25, p = 0.006). There was also a very significant difference between suicide attempters and nonattempters for the temperature (delta T degrees) responses to flesinoxan: 0.20 +/- 0.24 degrees C vs. 0.60 +/- 0.24 degrees C (F = 18.1, df = 5.25, p = 0.0003). Hormonal and temperature responses to flesinoxan were not correlated with BDHI irritability or assault subscale scores. The results of the present study support the implication of the serotonergic system, particularly 5-HT1A receptors, in the control of self-directed aggressive behavior. Moreover, in depressed patients, serotonergic abnormalities do not appear to be related to aggressive behavior. [less ▲]
