Abstract
We demonstrate the creation of vortices in a macroscopically occupied polariton state formed in a semiconductor microcavity. A weak external laser beam carrying orbital angular momentum (OAM) is used to imprint a vortex on the condensate arising from the polariton optical parametric oscillator (OPO). The vortex core radius is found to decrease with increasing pump power, and is determined by polariton-polariton interactions. As a result of OAM conservation in the parametric scattering process, the excitation consists of a vortex in the signal and a corresponding antivortex in the idler of the OPO. The experimental results are in good agreement with a theoretical model of a vortex in the polariton OPO.

Abstract
The killer immunoglobulin-like receptor (KIR) anthropology component of the 15th International Histocompatibility Workshop (IHIWS) sought to explore worldwide population variation in the KIR loci, and to examine the relationship between KIR genes and their human leukocyte antigen (HLA) ligands. Fifteen laboratories submitted KIR genotype and HLA ligand data in 27 populations from six broad ethnic groups. Data were analyzed for correlations between the frequencies of KIR and their known HLA ligands. In addition, allelic typing was performed for KIR2DL2 and 3DL1 in a subset of populations. Strong and significant correlations were observed between KIR2DL2, 2DL3 genotype frequencies and the frequency of their ligand, HLA-C1. In contrast, only weak associations were seen for 3DL1, 3DS1 and the HLA-Bw4 ligand. Although some aspects of the correlations observed here differ from those reported in other populations, these data provide additional evidence of linked evolutionary histories for some KIR and HLA loci. Investigation of allele-level variation for the B haplotype locus KIR 2DL2 showed that two alleles, *001 and *003, predominate in all populations in this study. Much more allelic variation was observed for the A haplotype locus 3DL1, with several alleles observed at moderate frequencies and extensive variation observed between populations.

Abstract
BACKGROUND Allergic rhinoconjunctivitis induced by pollen is a highly prevalent chronic inflammatory disease in Europe. Parietariajudaica is a frequent trigger in the Mediterranean area. The function of regulatory T cells (Treg cells) in allergy has recently been investigated, but further data are necessary to better understand their role and to find new strategies to treat allergic diseases such as allergic rhinoconjunctivitis. OBJECTIVE To characterize gene expression of HLA-DR+ or HLA-DR- on peripheral CD4+/CD25++/CD127low Treg cells in patients with allergy. METHODS Peripheral Treg cells (CD4+/CD25++/CD127low) were quantified using flow cytometry and sorted according to HLA-DR expression during the pollen season in patients with allergic rhinoconjunctivitis caused by P. judaica. The results were compared with those of nonatopic controls. Expression of associated cytokines and their receptors was measured using quantitative reverse transcription-polymerase chain reaction after extraction of mRNA in sorted populations. RESULTS During the pollen season, no significant differences were observed between allergic patients with rhinoconjunctivitis and healthy controls in terms of the absolute number or the percentage of Treg cells in peripheral blood. All patients had a higher number/percentage of HLA-DR- Treg cells than HLA-DR+ Treg cells. In both groups we found high levels of FOXP3 mRNA expression. Despite being lower in number, HLA-DR+ Treg cells presented higher expression of CD28, PRF1, GZMB, and FASL than HLA-DR-Treg cells. CONCLUSIONS The most relevant results obtained suggest that HLA-DR+ Treg cells tend to present higher gene expression of molecules associated with contact-dependent cell activation and cytotoxicity.

Abstract
AIM Assessing the perception of the aesthetic components of the oral health by paediatric patients at different stages of the child psychological development of Piaget. MATERIALS AND METHODS Twenty children aged between 21 months and 11 years, of both sexes, patients of a private clinic, were selected. The present study group consisted of patients treated for oral pathologies. A set of similar supplies was given to all children and they were asked to do a drawing, whose theme was "beautiful teeth and ugly teeth". The drawings were evaluated according to the classification of the cognitive development of Piaget. RESULTS Children of all ages clearly represent their perception of what "beautiful teeth" and "ugly teeth" are. These representations provide the dental professional a clear vision of the child's feeling about dental aesthetics. CONCLUSION The drawings are a useful source of information for assessing the aesthetic perception of paediatric patients. The knowledge of the children's aesthetic perception is relevant to paediatric dentists because children are conscious about their dental aesthetic appearance and that of the other children.

Abstract
Hexavalent chromium [Cr(VI)] is a well-recognized human lung carcinogen. In order to gain further insight into Cr(VI)-induced carcinogenesis, we have established an adequate in vitro cellular model for the study of this process. To this end, BEAS-2B cells were used. Chronic exposure of cells to 1 microM Cr(VI) induced changes in the cells' ploidy and a decrease in cloning efficiency, although cultures continued to progress to confluence. After prolonged exposure (12 passages), the culture became heterogeneous, exhibiting areas where apparently normal epithelial cells and morphologically altered cells coexisted. Subsequent culture at a very low density strongly accentuated the Cr(VI)-induced changes in morphology and pattern of growth. Three individual colonies were then ring-cloned and expanded into three subclonal aneuploid cell lines. These subclonal cell lines showed changes in growth pattern and morphology, as well as a karyotype drift concomitant with the overexpression of genes commonly involved in malignant transformation (c-MYC, EGFR, HIF-1alpha and LDH-A). Moreover, when one of these cell lines (RenG2) was injected into nude mice, it showed the ability to induce tumors. This cell line revealed no microsatellite instability (MSI), which points to the expression of a functional MLH1 protein and an active mismatch repair (MMR) system. Therefore, the progression to malignancy of the BEAS-2B cells involved Cr(VI)-induced transformants that retained the ability to repair DNA damage, suggesting that genotoxicity underlies the ongoing carcinogenic process.

Abstract
OBJECTIVE The purpose of this study was to examine the relationship between sexual maturation (SM), and the prevalence of overweight among boys and girls. SUBJECTS AND METHODS The sample of this cross-sectional study included 819 children and adolescents (382 boys and 437 girls), aged 10-15 years old randomly selected from 30 schools in the Porto region. Anthropometrical measurements (body height, weight and skinfolds thickness) were determined by standard anthropometrical methods. Body mass index (BMI) was calculated from the ratio weight/height(2) (kg/m(2)). The sum of tricipital and subscapular skinfolds (TriSub) was also used. Physicians collected data on Tanner stages during physical examination. Subjects were grouped using the quartiles of the decimal age adjusted for Tanner stages of SM and gender. RESULTS The prevalence of overweight was higher in early maturing boys (30.5%) and early maturing girls (32.7%). The late maturers presented a lower prevalence (p < 0.05) of overweight (20.3% boys and 18.3% girls). Logistic regression analysis illustrates that early maturing is associated with an increased risk for overweight or obesity for boys (OR: 1.87 and 95% CI: 0.99-3.50) and girls (OR: 2.14 and 95% CI: 1.12-4.07), when compared with the boys and girls of the fourth quartile (p < 0.05). CONCLUSIONS We conclude that there is an association between early SM and the prevalence of overweight in both genders.

Abstract
AIMS Health-related quality of life (HRQOL) is considered to be the key goal for health promotion in older people. This study explores the relationship between HRQOL and objectively measured intensity of physical activity (PA) in institutionalized older adults. The analysis of the PA patterns of the subjects in relation to recommended levels of PA was also performed. METHODS One hundred and eighty-five residents of long-term care homes aged 65 years or more, volunteered for this study. The Medical Outcome Study Short Form 36-Item health survey (MOS SF-36) questionnaires and the uni-axial MTI Actigraph were used to assess HRQOL and PA, respectively. Participants were classified as less active, reasonably active and more active by tertile of moderated physical activity (MPA). RESULTS (i) The men represented a greater number of counts/h and min of MPA in all the tertile groups; (ii) men from the less active group had a significantly higher body mass index; (iii) women came third and exhibited less total activity even though they used this time in more intense activities; (iv) there was a higher significant correlation between MPA, physical function and negative association with body pain in relation to the time of institutionalization in both sexes but was more strongly visible in men; and (v) only men presented a significant positive association with physical health, mental health and vitality. CONCLUSION Any intensity of PA seems to be better than no activity for HRQOL, but MPA confers greater benefits for the perception of physical function and body pain in the case of institutionalized elderly persons.

Abstract
The overall aim of the present study was to evaluate in vitro development ability of oocytes recovered from 56 Holstein Frisian heifers with low [group 1 (G1): <13 mg /dl], moderate [group 2 (G2): 13-16 mg /dl] and high [group 3 (G3): >16 mg /dl] plasma urea nitrogen (PUN) concentrations, to determine whether PUN concentrations affect the competence of oocytes to progress to blastocysts after in vitro fertilization. In vitro oocyte and embryo development was assessed by blastocyst rates, embryo total cell numbers and apoptosis. Blood samples for the determination of PUN were collected 24 h prior to collection of the ovaries at the slaughter. A total of 112 ovaries were collected at a local abattoir and oocytes (n = 697) were aspirated, in vitro matured and fertilized. On day 8, blastocysts were assigned to the terminal dUTP nick end labelling assay. Cleavage rates were significantly higher (p < 0.001) for groups 1 and 2 than for group 3 (i.e. 72.5% and 72.2% vs 61.7%, respectively). The proportion of fertilized oocytes that developed into blastocysts was higher (p < 0.05) for group 1 than for group 3 (34.0% vs 23.0%, respectively). Day 8 blastocysts showed higher total cell counts (p < 0.05) for group 1 than for group 3 (123.7 vs 76.3), and a higher (p < 0.05) total apoptotic cell rate was found in group 3 (25.9 and 19.0 vs 43.2 for G1, G2 and G3, respectively). In conclusion, the ability of oocytes from heifers with increased levels of PUN to develop to the blastocyst stage was significantly reduced when standard routines for in vitro maturation, fertilization and culture were followed. These detrimental effects can be mediated in part through direct effect of urea and/or by the metabolic products on the process of follicle-enclosed oocyte nuclear and cytoplasmic development.

Abstract
This study determined: the effects of α-tocopherol on apoptotic and necrotic levels of cumulus cells after in vitro maturation of bovine oocytes; whether exposure to α-tocopherol facilitates the development of bovine enclosed oocytes to metaphase II; and the effects of this antioxidant on apoptotic and necrotic levels of granulosa cells cultured in vitro. In conclusion, supplementation with α-tocopherol on in vitro maturation of bovine oocytes has a detrimental effect on the ability of oocytes to reach metaphase II, increasing the number of apoptotic and necrotic cumulus cells of bovine cumulus oocyte complexes (COC). This antioxidant showed a slight improvement in the viability of cultured granulosa cells at a concentration of 100 µM. Key words: Bovine, oocyte maturation in vitro, antioxidant, α-tocopherol

Abstract
The effects of a 3-month physical training programme on airway inflammation and clinical outcomes were studied in school-aged children with asthma. Subjects with persistent allergic asthma (aged 12.7+/-3.4 yrs; n = 34) were randomly allocated into training and control groups. Exercise consisted of twice-weekly 50-min sessions for 12 weeks. Inflammation was assessed by levels of exhaled nitric oxide, blood eosinophils, eosinophil cationic protein, C-reactive protein, and total and mite-specific immunoglobulin (Ig)E. Lung volumes and bronchial responsiveness to methacholine were determined. The Paediatric Asthma Quality of Life Questionnaire and Paediatric Asthma Caregiver's Quality of Life Questionnaire were used to evaluate activity restrictions, symptoms and emotional stress. The efficacy of the training was assessed by accelerometry. Following the programme, the exercise group spent twice as much time as the controls undertaking moderate-to-vigorous activities. No differences in changes were seen between groups for asthma outcomes. However, total IgE decreased more in the exercise group, as did mite-specific IgE. Training did not increase inflammation in children with persistent asthma, and may have decreased both total and allergen-specific immunoglobulin E levels. It is concluded that there is no reason to discourage asthmatic children with controlled disease to exercise.

Abstract
AIM The aim of this study was to establish physical fitness (PF) levels in a school population of 11-18-year-old students and analyse differences according to body mass index (BMI) status in overweight METHODS This is a cross-sectional study. The sample comprises 636 children and adolescents (mean age of 14.5+/-1.5 years), 288 boys (45.3%) and girls 347 (54.7%). Six tests from Fitness-gram battery were used as an objective measure of physical fitness. Overweight/ Obesity status was determined using age and sex adjusted cut-off points. RESULTS Both girls and boys with obesity performed a significantly reduced number of tests in healthy fitness zone suggesting a decrease of performances in strength and cardiovascular fitness, from normal weight status to overweight and from overweight to obesity. Boys and girls with obesity are likely to be Under HFZ than normal weight. CONCLUSION The results suggest that obese and overweight children have low PF level compared to normal weight peers. A large number of children with normal weight were identified as well as unfit. These data also showed that a low BMI level would significantly improve some PF component.
