The term third sector refers to a set of organizations which are neither capitalist, nor governmental. First of all, this paper aims to extent B. Gui's unitary approach to the third-sector (1991) by focusing on the distinction between third sector and state-owned bodies. Next I propose to translate the non capitalist and the non governmental conditions into operational criteria. I show that these criteria vary according to the nature of the organizations (general interest versus mutual interest). This statement allows me to justifiy the emergence of two different ways of understanding the third-sector in anglo-saxon and french-speaking traditions. [less ▲]

A new general method for the computation of nonradial nonadiabatic oscillations of a given stellar model is presented for a linear approximation. A simple and useful modelling of the atmosphere is included, allowing to obtain credible values for the eigenfunctions in the atmosphere. Some of the results obtained for a 10 M[SUB]sun[/SUB] model are shown as an illustration. Our study opens the way to different applications. Better theoretical line-profile variations could be obtained from our method, allowing a more detailed comparison with observations. More generally, our study is relevant for asteroseismology, giving a way for a better knowledge of stellar interiors. [less ▲]

OBJECTIVE: To assess the effect of mycophenolate mofetil compared with intravenous pulses of cyclophosphamide on the nonrenal manifestations of lupus nephritis. METHODS: Patients with active lupus nephritis (renal biopsy class III, IV, or V) were recruited for the study (n = 370) and treated with mycophenolate mofetil (target dosage 3 gm/day) or intravenous cyclophosphamide (0.5-1.0 gm/m(2)/month), plus tapered prednisone, for 24 weeks. Nonrenal outcomes were determined using measures of whole body disease activity, including the British Isles Lupus Assessment Group (BILAG) disease activity index, the Safety of Estrogens in Lupus Erythematosus: National Assessment (SELENA) version of the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), and immunologic variables. RESULTS: Both treatments were effective on whole body disease activity in the systems examined, as indicated by changes in the classic BILAG index. With either treatment, remission was induced, notably in the mucocutaneous, musculoskeletal, cardiovascular/respiratory, and vasculitis systems, and flares were rare, as measured by the SELENA-SLEDAI. Levels of complement C3, C4, and CH50 and titers of anti-double-stranded DNA antibodies were normalized after treatment with either mycophenolate mofetil or intravenous cyclophosphamide. CONCLUSION: In addition to the efficacy of both treatments on the renal system, this analysis showed that remission could also be induced in other systems. There was no clear difference in efficacy between mycophenolate mofetil and intravenous cyclophosphamide in ameliorating either the renal or nonrenal manifestations. Mycophenolate mofetil is, therefore, a suitable alternative to cyclophosphamide for the treatment of renal and nonrenal disease manifestations in patients with biopsy-proven lupus nephritis.

A case of concurrent canine systemic lupus erythematosus (SLE) and generalized bacterial infection in a six-year-old female Beauceron is reported. The dog presented with purulent nasal and ocular discharges, skin lesions (including seborrhea, hyperkeratotic areas, and papules as well as ecchymoses around the eyes, on both sides of the pinnae, and on the vulva), generalized lymph node enlargement, a mitral murmur, and lameness. Later, facial swelling, a retrobulbar abscess, and a cough also developed. Occurrence of a generalized bacterial infection was established by culture of group-C, beta-hemolytic Streptococcus from the throat, the mouth, a biopsy site (popliteal lymph node area), the retrobulbar abscess, and the lung. The diagnosis of SLE was based on the clinical signs and particularly on the occurrence of antinuclear antibody (ANA) and antidoublestranded-desoxyribonucleic acid (ds-DNA) antibody. Interestingly, the latter type of antibodies were also detected in two young female puppies whelped by this dog. Salient histological findings included an extreme cell depletion of the lymph nodes and spleen and severe pneumonitis and peribronchiolitis. The results of this case indicate that a definite diagnosis of canine SLE can, at times, be made on the basis of the presence of serum ANA and ds-DNA antibodies. [less ▲]

Historically, dwarfism was the major genetic defect in U.S. beef cattle. Aggressive culling and sire testing were used to minimize its prevalence; however, neither of these practices can eliminate a recessive genetic defect. We assembled a 4-generation pedigree to identify the mutation underlying dwarfism in American Angus cattle. An adaptation of the Elston-Steward algorithm was used to overcome small pedigree size and missing genotypes. The dwarfism locus was fine-mapped to BTA6 between markers AFR227 and BM4311. Four candidate genes were sequenced, revealing a nonsense mutation in exon 15 of cGMP-dependant type II protein kinase (PRKG2). This C/T transition introduced a stop codon (R678X) that truncated 85 C-terminal amino acids, including a large portion of the kinase domain. Of the 75 mutations discovered in this region, only this mutation was 100% concordant with the recessive pattern of inheritance in affected and carrier individuals (log of odds score = 6.63). Previous research has shown that PRKG2 regulates SRY (sex-determining region Y) box 9 (SOX9)-mediated transcription of collagen 2 (COL2). We evaluated the ability of wild-type (WT) or R678X PRKG2 to regulate COL2 expression in cell culture. Real-time PCR results confirmed that COL2 is overexpressed in cells that overexpressed R678X PRKG2 as compared with WT PRKG2. Furthermore, COL2 and COL10 mRNA expression was increased in dwarf cattle compared with unaffected cattle. These experiments indicate that the R678X mutation is functional, resulting in a loss of PRKG2 regulation of COL2 and COL10 mRNA expression. Therefore, we present PRKG2 R678X as a causative mutation for dwarfism cattle. [less ▲]

Mechanical systems are usually subjected not only to bilateral constraints but also to unilateral constraints. Inspired by the generalized-alpha time integration method for smooth flexible multibody dynamics, this paper presents a nonsmooth generalized-alpha method, which allows a consistent treatment of the nonsmooth phenomena induced by unilateral constraints and an accurate description of the structural vibrations during free motions. Both the algorithm and the implementation are illustrated in detail. Numerical example tests are given in the scope of both rigid and flexible body models, taking account for both linear and nonlinear systems, and comprising both unilateral and bilateral constraints. The extended nonsmooth generalized-alpha method is verified through comparison to the traditional Moreau-Jean method and the fully implicit Newmark method. Results show that the nonsmooth generalized-alpha method benefits from the accuracy and stability property of the classical generalized-alpha method with controllable numerical damping. In particular, when it comes to the analysis of flexible systems, the nonsmooth generalized-alpha method shows much better accuracy property than the other two methods. [less ▲]

The brain processes light information to visually represent the environment but also to detect changes in ambient light level. The latter information induces non-image-forming responses and exerts powerful effects on physiology such as synchronization of the circadian clock and suppression of melatonin. In rodents, irradiance information is transduced from a discrete subset of photosensitive retinal ganglion cells via the retinohypothalamic tract to various hypothalamic and brainstem regulatory structures including the hypothalamic suprachiasmatic nuclei, the master circadian pacemaker. In humans, light also acutely modulates alertness, but the cerebral correlates of this effect are unknown. We assessed regional cerebral blood flow in 13 subjects attending to auditory and visual stimuli in near darkness following light exposures (>8000 lux) of different durations (0.5, 17, 16.5, and 0 min) during the biological night. The bright broadband polychromatic light suppressed melatonin and enhanced alertness. Functional imaging revealed that a large-scale occipito-parietal attention network, including the right intraparietal sulcus, was more active in proportion to the duration of light exposures preceding the scans. Activity in the hypothalamus decreased in proportion to previous illumination. These findings have important implications for understanding the effects of light on human behavior. [less ▲]

Children with specific language impairment (SLI) consistently show poor nonword repetition (NWR) performance. However, the reason for these difficulties remains a matter of intensive debate. Nonword repetition is a complex psycholinguistic task that heavily relies upon phonological segmentation and phonological knowledge, and even lexical knowledge. This study aims at investigating various linguistic factors that can be at the root of difficulties in children with Specific Language Impairment when repeating nonwords, with the goal of achieving a better understanding of the linguistic processes supporting nonword processing. Linguistic complexity was assessed by manipulating lexicality, syllabic complexity, and perceptual difficulty in NWR tasks. Fifteen children with Specific Language Impairment, 15 typically developing controls matched on both age and performance IQ, and 15 typically developing children matched on lexical knowledge participated in this study. Children with Specific Language Impairment performed overall more poorly than age- and IQ-matched children and lexical age-matched children. Importantly, children with Specific Language Impairment showed lower lexicality and syllabic complexity effects in their NWR performances. These results are compatible with difficulties to retrieve lexical and sublexical phonological knowledge in the context of NWR tasks.

An ethological procedure, based on the study of the sexual responsiveness of female canaries (Serinus canaria) to song playbacks was used to investigate the function of central noradrenergic inputs in the processing of auditory information. The effects of a noradrenergic denervation on sexual responses was analyzed in females exposed to playbacks of biological relevant auditory stimuli, i.e. sexually stimulating songs, presented alone or masked by auditory distractors. A decrease in behavioral responsiveness was observed as a function of the amount of masking distractors indicating that female canaries have the perceptual ability to discriminate and selectively attend to biologically relevant songs. After the systemic administration of DSP-4, a specific noradrenergic neurotoxin, females exhibited an overall decrease in sexual responsiveness to songs masked or not by distractors. No effect of DSP-4 were detected on the motor activity nor on reproductive behaviors. These results indicate that central noradrenergic inputs modulate the sexual behavior of female canaries by affecting the auditory processing of relevant information contained in sexually stimulating songs.
