A plant hormone is not, in the classic animal sense, a chemical synthesized in one organ, transported to a second organ to exert a chemical action to control a physiological event. Any phytohormone can be synthesized everywhere and can influence different growth and development processes at different places. The concept of physiological activity under hormonal control cannot be dissociated from changes in concentrations at the site of action, from spatial differences and changes in the tissue's sensitivity to the compound, from its transport and its metabolism, from balances and interactions with the other phytohormones, or in their metabolic relationships, and in their signaling pathways as well. Secondary messengers are also involved. Hormonal involvement in physiological processes can appear through several distinct manifestations (as environmental sensors, homeostatic regulators and spatio-temporal synchronizers, resource allocators, biotime adjusters, etc.), dependent on or integrated with the primary biochemical pathways. The time has also passed for the hypothesized 'specific' developmental hormones, rhizocaline, caulocaline, and florigen: root, stem, and flower formation result from a sequential control of specific events at the right places through a coordinated control by electrical signals, the known phytohormones and nonspecific molecules of primary and secondary metabolism, and involve both cytoplasmic and apoplastic compartments. These contemporary views are examined in this review. [less ▲]

Paedomorphosis, in which individuals retain ancestral characteristics in the adult stage, is widespread in newts and salamanders and is suspected to play an important role in evolution. In some species, paedomorphosis is facultative with some individuals skipping the metamorphic stage. Dimorphic populations of the Alpine newt inhabit a large variety of aquatic habitats such as permanent lakes and temporary ponds. The aim of this study was to determine the benefits of the alternatives in these different habitats. To this end, I focused on resource partitioning, energy intake, body condition and age structures in different populations composed of the two morphs. In deep lakes, there was a substantial trophic differentiation between morphs. Paedomorphs primarily preyed on plankton whereas metamorphs foraged on terrestrial invertebrates that fell to the water surface. By reducing competition, resource partitioning may contribute to the coexistence of the alternative morphs in heterogeneous habitats. On the contrary, in a small pond, resource use was similar in the two morphs. Maturity is reached earlier in the paedomorphs from this small pond than in metamorphs (progenetic process), favoring then a rapid turn-over of the population, while similar gonadal development was observed in one of the deep lakes (neotenic process). Body condition was generally higher in paedomorphs than in metamorphs in each studied population. These results show that facultative paedomorphosis is adaptive in varied habitats, but that different factors may favor it depending of the characteristics of the environment. Paedomorphic phenotypes can thus be selected in low altitude productive ponds and high altitude oligotrophic lakes. [less ▲]

It has often been claimed that writing about music is like dancing about architecture. The general distrust of methods that combine or aggregate knowledge from different research fields, and therefore tend to elide or smooth out some of their particularities, may account for the paucity of critical writing dealing not only with the role of voice and song in poetry but also with the history of the interdependencies of verbal, textual and musical materials in the broader context of contemporary American literature. The purpose of this book is to develop an informed and imaginative understanding of the interrelationships between poetry and music in a way that reflects the diversity and richness of contemporary artistic practice in the US since the beginning of the 20th century. Related topics such as theories of representation, the aesthetics of rhythm, the material production of literature and music, the links between poetry, politics and popular culture, the making of music from literary texts,or literature from musical models, all provide the focus for a study that deals with the theoretical and practical interrelationships between poetry and music.

The rac mutant of Nicotiana tabacum L. cv. Xanthii is impaired in adventitious root formation. The objective of the present study was to determine whether or not the root induction phase occurs in the rac mutant, and if so, to determine what causes the induced cells to become incapable of organising root primordia. To this end, rac and wild-type shoots were cultured in vitro for 7 days under conditions suitable for obtaining roots in the wild-type (i.e., exposure to 5 muM indole-3-butyric acid for 4 h, and then transfer to hormone-free medium), and then histologically and biochemically analysed during culture. The variations in peroxidase activity, and in cellular levels of auxins and polyamines revealed that the induction phase occurs in rac shoots, although it lasts longer than in the wild-type ones. Furthermore, both auxin and polyamines were consistently higher in rac shoots compared to the wild-type. After induction, auxin and putrescine levels abruptly decreased in the wild-type shoots, whereas they decreased much more slowly in the rac mutant. The histological analysis of the wild-type shoots showed that the abrupt decrease in auxin and polyamine levels were correlated with a normal initiation phase. In fact, wild-type shoots showed cell divisions in the procambium already at day 2, resulting in the formation of root primordia at day 4, and in root emergence between days 5 and 7. In rac shoots, despite the fact that the procambium cells were activated to undergo cell division, the initiation phase was highly perturbed, and the procambial cells developed tracheary elements instead of adventitious roots. The different morphogenic responses of the two genotypes are discussed in the light of the differences in auxin content after the induction phase. [less ▲]

Acetaldehyde, the first ethanol metabolite, was recently suggested to play a major role in many behavioral effects of ethanol. However, no studies have directly investigated the behavioral effects of acetaldehyde after acute administration. Therefore, the aim of the present study was to characterize the locomotor, hypnotic and ataxic effects of acetaldehyde in C57BL/6J mice. Various acetaldehyde doses (0-300 mg/kg) were injected intraperitoneally and their effects were investigated with several classical behavioral tests. The locomotor effects of acetaldehyde were measured in standard activity boxes. In addition, the loss of righting reflex was used to assess the hypnotic effects of acetaldehyde. Finally, the ataxic effects of acetaldehyde were studied with the horizontal wire test. The results show that acetaldehyde induced a significant hypolocomotor effect at 170 mg/kg and higher doses. In addition, the hypnotic effects of acetaldehyde were evidenced by a loss of righting reflex in doses between 170 and 300 mg/kg. However, the locomotor and hypnotic effects of acetaldehyde were very brief relative to what is observed after ethanol administration. After 170 mg/kg acetaldehyde, normal activity was recovered in less than 30 minutes and the loss of righting reflex lasted only an average of 6.14 ± 1.29 minutes after the administration of 300 mg/kg acetaldehyde, the highest testable dose before lethality. Ataxic effects were observed with lower doses that did not significantly affect locomotor activity. These results show that acetaldehyde, like ethanol, possesses sedative, hypnotic and ataxic properties and therefore indicate that the first product of ethanol metabolism might be involved in these ethanol effects.

The phase 3 program for strontium ranelate, a new oral agent in the treatment of women with postmenopausal osteoporosis, was aimed to assess the efficacy and safety of the daily oral dose of 2 g. This program was conducted in 12 countries, involved 75 centers, and was structured in 3 studies: FIRST (Fracture International Run-in for Strontium ranelate Trial), SOTI (Spinal Osteoporosis Therapeutic Intervention study) and TROPOS (TReatment Of Peripheral OSteoporosis). FIRST, a run-in open study, was designed to start the normalization of the calcium and vitamin D status of the patients, check all entry criteria, and ensure inclusion of a sufficient number of well-motivated patients in either one of the two therapeutic intervention protocols, SOTI or TROPOS: FIRST included 9,196 patients. SOTI and TROPOS were prospective, randomized, double-blind clinical trials comparing, in two parallel groups, the daily oral dose of 2 g of strontium ranelate with placebo, the patients of both groups receiving calcium and vitamin D according to their own deficiencies. The main objective of SOTI and TROPOS was to demonstrate a reduction in the incidence of postmenopausal women experiencing a new osteoporotic fracture (vertebral fracture in SOTI and nonvertebral fracture in TROPOS) over a 3-year treatment period, the total duration of the studies being 5 years. SOTI included 1,649 women with at least one osteoporotic vertebral fracture at inclusion and a lumbar BMD less than or equal to 0.840 g/cm(2). TROPOS included 5,091 women with a femoral neck BMD less than or equal to 0.600 g/cm(2). The phase 3 program for the clinical development of strontium ranelate in women with postmenopausal osteoporosis is a long-term program with the main statistical analysis after 3 years of treatment. Its aim is to demonstrate the effect of strontium ranelate on the axial and appendicular skeleton as well as its tolerability in osteoporotic patients with replete calcium and vitamin D stores.
