THE EFFECTS OF PEOPLES’ HEIGHT AND RELATIVE HEIGHT ON WELL-BEING

Using a rich Italian survey, we investigate the effect of height on individual happiness. From our analysis it emerges that a large part of the effect of height on well-being is driven by a positive correlation between height and economic and health conditions. However, for young males the effect of height on happiness persists even after controlling for these variables, implying that height may produce some psycho-social direct effects on well-being. Consistent with this hypothesis, we find that males care not only about their own height but also about the height of people in their reference group. Well-being is greater for individuals who are taller than other subjects in their reference group. Results are robust to different definitions of reference group and controlling for a number of other reference group characteristics. We speculate that the beneficial effect of height on young males' well-being may be related to the fact that in some countries, such as Italy, and especially for men, height is considered as a proxy for handsomeness.height, social comparison, subjective well-being

Daily functioning, problem solving and satisfaction for quality of life in visually impaired old persons

Aim: The purpose of this study was to investigate the impact of several dimensions of functioning on satisfaction for quality of life (QoL) experienced by visually impaired older adults. Participants: A sample of 58 older adults (37 women and 21 men) was involved in the study. Their age ranged from 50 to 88 years (M=68.95, SD=1.51). They were characterized by visual impairment of different origin and visual acuity (VA) ranging from 4/10 to total blindness. The QoL questionnaire was used along with short form-12 health Survey, the National Eye Institute visual function questionnaire-25 and problem solving inventory (PSI) which analyzes problem solving appraisal. Results: A stepwise regression analysis was conducted in order to find predictors of satisfaction for QoL. A contribution of mental and physical health, more specifically, of problem solving appraisal was found. Conclusion: Results support the notion that the functional relationship between visual impairment and satisfaction for QoL must be understood in terms of approaches that incorporate psychological and socio-cognitive elements. Problem solving appraisal, in fact, makes a substantial contribution to the prediction of variance in life satisfaction and it may play an important role for intervention strategies

Caracterização antigênica e genética do primeiro isolado de vírus da raiva em morcego Eumops perotis no Brasil

Although the main transmitters of rabies in Brazil are dogs and vampire bats, the role of other species such as insectivorous and frugivorous bats deserves special attention, as the rabies virus has been isolated from 36 bat species. This study describes the first isolation of the rabies virus from the insectivorous bat Eumops perotis. The infected animal was found in the city of Ribeirão Preto, São Paulo. The virus was identified by immunofluorescence antibody test (FAT) in central nervous system (CNS) samples, and the isolation was carried out in N2A cell culture and adult mice. The sample was submitted to antigenic typing using a panel of monoclonal antibodies (CDC/Atlanta/USA). The DNA sequence of the nucleoprotein gene located between nucleotides 102 and 1385 was aligned with homologous sequences from GenBank using the CLUSTAL/W method, and the alignment was used to build a neighbor-joining distance-based phylogenetic tree with the K-2-P model. CNS was negative by FAT, and only one mouse died after inoculation with a suspension from the bat's CNS. Antigenic typing gave a result that was not compatible with the patterns defined by the panel. Phylogenetic analysis showed that the virus isolated segregated into the same cluster related to other viruses isolated from insectivorous bats belonging to genus Nyctinomops ssp. (98.8% nucleotide identity with each other).No Brasil, embora os principais transmissores da raiva sejam cães e morcegos hematófagos, o papel de outras espécies, tais como morcegos insetívoros e frugívoros, merece atenção especial, uma vez que o vírus da raiva já foi isolado em 36 espécies de morcegos. Este estudo descreve o primeiro isolamento do vírus da raiva em um morcego insetívoro Eumops perotis. O animal infectado foi encontrado na cidade de Ribeirão Preto, São Paulo. O vírus foi identificado pelo teste de imunofluorescência direta (IFD) em amostras de sistema nervoso central (SNC), e o isolamento foi realizado em cultura de células N2A e em camundongos adultos. A amostra foi submetida à tipificação antigênica, utilizando um painel de oito anticorpos monoclonais (CDC/Atlanta/USA). A seqüência de DNA do gene da nucleoproteína, localizada entre os nucleotídeos 102 a 1385, foi alinhada com seqüências homólogas presentes no GenBank, usando o método CLUSTAL/W e o alinhamento foi utilizado para a construção da árvore filogenética de distância "neighbor-joining" com o modelo K-2-P. O SNC testado foi negativo por IFD, e somente um camundongo morreu após inoculação com a suspensão do SNC do morcego. A tipificação antigênica apresentou resultado não-compatível com os padrões definidos pelo painel. A análise filogenética mostrou que o vírus isolado segregou no mesmo grupo relacionado com outros vírus isolados de morcegos insetívoros, gênero Nyctinomops ssp. (98,8% de identidade de nucleotídeos entre elas)

Urinary levels of free 2,5-hexanedione in Italian subjects non-occupationally exposed to n-hexane

The purpose of the study is to evaluate the urinary levels of free 2,5-hexanedione (2,5-HD) in Italian subjects non-occupationally exposed to n-hexane, in order to define background values in non-occupational settings. The study was carried out on 99 subjects of the general population. The analysis of free 2,5-HD was performed by gas chromatography-mass spectrometry. Personal information about the subjects was ascertained by means of a self-administered questionnaire. The urinary levels of free 2,5-HD were in the range of <12.0\u201377.9 g/L (5th\u201395th percentiles). The urinary excretion of the metabolite did not seem to be influenced by gender, age, smoking habit or area of residence. Statistically significant dierences (p = 0.03) were found between the free 2,5-HD urinary levels according to the vehicular trac intensity within the area of residence and to body mass index of subjects. The background levels of free 2,5-HD found in this study could contribute to the definition of reference values of general population non-occupationally exposed and could be useful to the toxicologists and industrial hygienists to determine whether workers have been exposed to higher levels of n-hexane than the general population

Sensitivity of the Immunohistochemistry technique in central nervous system fragments of cattle and horses naturally infected by rabies virus

A raiva é uma zoonose viral que acomete o sistema nervoso central (SNC) de mamíferos, considerada um grave problema de saúde pública. Herbívoros (bovinos e equinos) são frequentemente acometidos pela in-fecção após serem atacados por morcegos hematófagos (Desmodus rotundus). A técnica de imunofluorescência direta (IFD) realizada em tecidos frescos, recomendada pela Organização Mundial de Saúde (OMS), é utilizada para o diagnóstico da raiva. A técnica de imuno-histoquímica (IHQ) é utilizada para detectar antígenos em tecidos fixados, pelo uso de anticorpos monoclonais/policlonais. O objetivo deste trabalho foi avaliar a sensibilidade da IHQ na detecção de antígenos do vírus da raiva em amostras de SNC de herbívoros fixadas em formol, analisando a distribuição antigênica em diferentes fragmentos do SNC. Os resultados demonstraram concordância das técnicas de IFD e IHQ. A IHQ mostrou maior sensibilidade em amostras de bovinos em relação às de equinos, especialmente quando realizada em fragmentos de cerebelo e tronco encefálico. A detecção de antígeno nestes fragmentos foi mais consistente para ambas as técnicas, nas duas espécies. Estes resultados demonstram que a IHQ pode ser empregada para a vigilância epidemiológica da raiva, entretanto, recomenda-se cautela ao se empregar a IHQ para diagnóstico de doença em herbívoros, especialmente quando o fragmento encaminhado ao laboratório for apenas o hipocampo.Rabies is a viral zoonosis that causes disease in the central nervous system (CNS) of mammals and it is considered a serious problem of public health. Herbivorous (bovines and equines) are often infected after being attacked by vampire bats (Desmodus rotundus). The direct fluorescent antibody technique is used as a diagnostic test to detect viral antigens in fresh tissues and is recommended by the World Health Organization. The immunohistochemistry technique (IHC) is used to detect the viral antigen through the use of monoclonal/policlonal antibodies in formalin-fixed tissues. The aim of this work was to evaluate the sensitivity of the IHC in samples of CNS of herbivorous fixed in formol, analyzing the antigenic distribution in different fragments of the CNS. The results demonstrated good agreement between the two techniques for the rabies diagnosis. The IHC presented higher sensitivity in samples of cattle comparing to horse samples, especially in fragments of cerebellum and brain stem. These fragments demonstrated to be more suitable for antigen detection by both techniques in the two species. These data demonstrate that the IHC is suitable for rabies vigilance yet cautions should be taken in examining cattle and horses samples, when the submitted specimen is only the hippocampus

Antigenic typing of brazilian rabies virus samples isolated from animals and humans, 1989-2000

Animal and human rabies samples isolated between 1989 and 2000 were typified by means of a monoclonal antibody panel against the viral nucleoprotein. The panel had been previously established to study the molecular epidemiology of rabies virus in the Americas. Samples were isolated in the Diagnostic Laboratory of the Pasteur Institute and in other rabies diagnostic centers in Brazil. In addition to the fixed virus samples CVS-31/96-IP, preserved in mouse brain, and PV-BHK/97, preserved in cell culture, a total of 330 rabies virus samples were isolated from dogs, cats, cattle, horses, bats, sheep, goat, swine, foxes, marmosets, coati and humans. Six antigenic variants that were compatible with the pre-established monoclonal antibodies panel were defined: numbers 2 (dog), 3 (Desmodus rotundus), 4 (Tadarida brasiliensis), 5 (vampire bat from Venezuela), 6 (Lasiurus cinereus) and Lab (reacted to all used antibodies). Six unknown profiles, not compatible with the panel, were also found. Samples isolated from insectivore bats showed the greatest variability and the most commonly isolated variant was variant-3 (Desmodus rotundus). These findings may be related to the existence of multiple independent transmission cycles, involving different bat species.Amostras de vírus rábico isoladas de animais e humanos no período de 1989 a 2000 foram tipificadas antigenicamente com a utilização de um painel de anticorpos monoclonais contra a nucleoproteína viral, pré-estabelecido para o estudo da epidemiologia molecular do vírus rábico isolado nas Américas. As amostras testadas foram isoladas no laboratório de diagnóstico do Instituto Pasteur e outros centros de diagnóstico de raiva no Brasil. Além das cepas de vírus rábico fixo CVS-31/96-IP, mantida em cérebro de camundongos e a PV-BHK/97, mantida em cultura de células, cepas de vírus rábico isoladas de cães, gatos, bovinos, eqüinos, morcegos, ovinos, caprino, suínos, raposa, sagüí, coatí, guaxinim e humanos, totalizaram 330 amostras. Seis variantes antigênicas foram definidas, compatíveis com perfís observados no painel de anticorpos monoclonais pré-estabelecido utilizado, as de número 2 (cão), 3 (Desmodus rotundus), 4 (Tadarida brasiliensis), 5 (Vampiro da Venezuela), 6 (Lasiurus cinereus) e Lab (reagente a todos os anticorpos utilizados), além de outros seis perfís desconhecidos, não compatíveis com aqueles observados no painel utilizado. A maior variabilidade foi observada entre as amostras isoladas de morcegos insetívoros e a variante mais comum isolada entre as espécies foi a variante 3 (Desmodus rotundus). Estes fatos podem representar a existência de múltiplos ciclos de transmissão independentes, envolvendo diferentes espécies de morcegos
