Directions De Majoration D'une Fonction Quasiconvexe Et Applications

We introduce the convex cone constituted by the directions of majoration of a quasiconvex function. This cone is used to formulate a qualification condition ensuring the epiconvergence of a sequence of general quasiconvex marginal functions in finite dimensional spaces.

Effects of Recession versus Tenotomy Surgery without Recession in Adult Rabbit Extraocular Muscle

PURPOSE. Surgical recession of an extraocular muscle (EOM) posterior to its original insertion is a common form of strabismus surgery, weakening the rotational force exerted by the muscle on the globe and improving eye alignment. The purpose of this study was to assess myosin heavy chain (MyHC) isoform expression and satellite cell activity as defined by Pax7 expression in recessed EOMs of adult rabbits compared with that in muscles tenotomized but not recessed and with that in normal control muscles. METHODS. The scleral insertion of the superior rectus muscle was detached and sutured either 7 mm posterior to its original insertion site (recession surgery) or at the same site (tenotomy). One day before euthanatization, the rabbits received bromodeoxyuridine (BrdU) injections. After 7 and 14 days, selected EOMs from both orbits were examined for changes in fast, slow, neonatal, and developmental MyHC isoform expression, Pax7 expression, and BrdU incorporation. RESULTS. Recession and tenotomy surgery resulted in similar changes in the surgical EOMs. These included a decreased proportion of fast MyHC myofibers, an increased proportion of slow MyHC myofibers, and increased BrdU-positive satellite cells. Similar changes were seen in the non-operated contralateral superior rectus muscles. The ipsilateral inferior rectus showed reciprocal changes to the surgical superior rectus muscles. CONCLUSIONS. The EOMs are extremely adaptive to changes induced by recession and tenotomy surgery, responding with modulations in fiber remodeling and myosin expression. These adaptive responses could be manipulated to improve surgical success rates. (Invest Ophthalmol Vis Sci. 2010;51:5646-5656) DOI:10.1167/iovs.10-5523

Gingival recession in maxillary canines and central incisors of individuals with clefts

Background. Mucogingival alterations are inherent to clefts and may be worsened by the several plastic surgeries required in these individuals. Objective. The aim of this study was to evaluate the prevalence, severity, and some possible etiologic factors of gingival recessions in teeth adjacent to the cleft. Study design. A total of 641 teeth ( maxillary canines and central incisors) of 193 individuals with cleft lip and/or palate were examined. A generalized linear model was used, and the Wilcoxon test was used to compare the recession with cleft types. Results. Comparison among cleft types as to the presence of recession revealed a statistically significant positive relationship for the maxillary right and left central incisors only in the group with left cleft lip, alveolus, and palate (P = .034). The most frequently affected tooth was the right maxillary canine (26.16%). Conclusion. The prevalence of recession in teeth close to the cleft was higher, although it was not very severe.

Elaboração de um manual de fabrico de cones

O cone de bolacha é um produto alimentar muito consumido, pois está associado ao gelado, que é um produto de muito sucesso. O cone de bolacha é o resultado de uma mistura de ingredientes (farinha de trigo, açúcar, lecitina de soja, amido de batata, caramelo, água e sal) que é homogeneizada e cozida. O seu fabrico percorre vários processos de produção, que vão desde a formulação da receita, até ao armazenamento do produto e à sua transferência para a Fábrica de Gelados da Olá, para a produção do gelado Cornetto. Como a garantia da qualidade dos produtos alimentares, e deste em particular, é de uma extrema importância, torna-se relevante o estudo de todos os seus mecanismos de fabrico, e dos parâmetros de controlo indispensáveis para o êxito do produto, e para a segurança do consumidor. Para garantir a manutenção da qualidade são apresentadas ferramentas de TPM. O objetivo principal desta Dissertação é apresentar um Manual de fabrico de Cones de Bolacha. Para a sua elaboração focaram-se não só as áreas de produção e de tecnologia, mas também as áreas de gestão, de qualidade e segurança alimentar. O estudo subjacente a este trabalho, realizou-se na nova Fábrica de Cones da Olá, situada em Santa Iria da Azóia.

Facing the challenge: The impact of the recession and unemployment on men's health in Ireland

The economic recession with its accompanying rise in unemployment rates is linked to extremely adverse effects for men’s mental health. This research report Facing the Challenge – The Impact of the Recession and Unemployment on Men’s Health in Ireland identifies a strong expectation of increased mental health problems for men given the very strong correlation between unemployment and male mental ill health. The report is the result of a research and consultation process carried out, in Northern Ireland and the Republic of Ireland, by Nexus Research Co-operative on behalf of IPH. 93% of frontline organisations, North and South, in contact with unemployed men linked health challenges to unemployment and recession and all organisations surveyed noted adverse health challenges for men they work with. In addition to health challenges being higher for unemployed men, they were also very high for men who saw themselves as being threatened with unemployment. The organisations surveyed and the men who were interviewed identified the challenges to health as:•    High levels of stress or anxiety•    Dependency on or over-use of alcohol/other drugs•    Deterioration in physical health•    Development of conflict in family or close personal relationships•    Isolation (including sharing or communicating problems)•    A reluctance to approach services or seek help

Reduction theorems for operators on the cones of monotone functions

For a quasilinear operator on the semiaxis a reduction theorem is proved on the cones of monotone functions in Lp - Lq setting for 0 < q < ∞, 1<= p < ∞. The case 0 < p < 1 is also studied for operators with additional properties. In particular, we obtain critera for three-weight inequalities for the Hardy-type operators with Oinarov' kernel on monotone functions in the case 0 < q < p <= 1.

Esotropie précoce: résultats à long terme d'une série de 82 cas opérés par myopexie rétro-équatoriale et recul simultané des deux muscles droits médiaux avant l'âge de 24 mois [Early-onset esotropia operated before the age of 24 months: long-term results of Cüpper's retropexy combined with simultaneous recession of both medial recti]

BACKGROUND: When and how to operate an early-onset esotropia (onset before 6 months of age) is still controversial. We conducted a retrospective study of such patients operated before the age of 24 months. PATIENTS AND METHODS: 82 patients were operated by one surgeon (GK) and followed by the same team. At 5 years post-operation, evaluation criteria included the residual angle of deviation, visual acuity (Birkhäuser Nr 505, 5 m) and binocularity (Lang stereotest I, Bagolini glasses). RESULTS: At 5 years, the residual angle was excellent (0 degrees to + 5 degrees ) in 67 % good, (>+5 degrees to +10 degrees or 0 to -5 degrees ) in 23 %, and poor (>+10 degrees or <-5 degrees ) in 10 %. During the 5 years of follow-up the rate of reoperation was 9.7 %. Isoacuity was obtained in 62 %, slight amblyopia (2 lines of interocular difference) was present in 32 %, and average amblyopia (> 3 lines of interocular difference) was noted in 6 %. Simultaneous perception was present in 53 %, whereas one eye was suppressed or results were undetermined in 47 %. No patient demonstrated stereoscopy using the Lang's stereotest I. CONCLUSION: The results from our study demonstrate that early surgery of early-onset esotropia has a favourable outcome on both visual acuity and the residual angle of strabismus. Simultaneous perception was achieved in 53 %. These figures are comparable to the results of the ELISSS multicentric study.

Regulated exocytosis of an H+/myo-inositol symporter at synapses and growth cones.

Phosphoinositides, synthesized from myo-inositol, play a critical role in the development of growth cones and in synaptic activity. As neurons cannot synthesize inositol, they take it up from the extracellular milieu. Here, we demonstrate that, in brain and PC12 cells, the recently identified H(+)/myo-inositol symporter HMIT is present in intracellular vesicles that are distinct from synaptic and dense-core vesicles. We further show that HMIT can be triggered to appear on the cell surface following cell depolarization, activation of protein kinase C or increased intracellular calcium concentrations. HMIT cell surface expression takes place preferentially in regions of nerve growth and at varicosities and leads to increased myo-inositol uptake. The symporter is then endocytosed in a dynamin-dependent manner and becomes available for a subsequent cycle of stimulated exocytosis. HMIT is thus expressed in a vesicular compartment involved in activity-dependent regulation of myo-inositol uptake in neurons. This may be essential for sustained signaling and vesicular traffic activities in growth cones and at synapses.
