Vulnerability during pregnancy in an urban environment : do environmental and individual risk factors cumulate?

2018

International audience; Apart from demographic, socio-economic, behavioral, nutritional and medico-obstetrical factors, environmental factors have been suggested to be associated with adverse pregnancy outcomes, such as preterm birth, low birth weight or hypertensive disorders. According to a recent review of the literature, there is some suggestive evidence of adverse associations with environmental noise especially for low birth weight. However, the way these individual and environmental vulnerabilities combine has been scarcely studied. The objective of this study was to describe the accumulation of individual, socio-economics, medical and environmental vulnerability markers and to asses…

Indoor noise exposure assessment of primary school children living in a french urban area

2012

International audience; The recent development of powerful noise mapping softwares allows to assess the exposure to environmental noise at the scale of an agglomeration. However noise levels inside dwellings are still unknown at such scales. To evaluate indoor noise levels and to investigate the factors which determine them, an eight-day noise measurement campaign was carried out in 50 children’s home. These children were randomly chosen among 8 or 9-year-old pupils attending the public primary schools of Besançon (France). Microphones were placed in the child’s bedroom, outdoor in front of the bedroom’s facade, and in the main room. Equivalent sound pressure levels (LAeq) were calculated d…

Efecto de la radiación ionizante persistente a bajas dosis en la angiogénesis del carcinoma renal de células claras : estudio morfométrico comparativ…

2013

La angiogénesis en el carcinoma de células renales claras (ccRCC) es un proceso influenciado por sustancias producidas en su mayoría por el tumor en respuesta a una reestructuración vascular necesaria en su etapa de crecimiento y metástasis. La exposición persistente a bajas dosis de radiación ionizante (CPLDIR) ha sido asociada a modificaciones nucleares que estimulan la proliferación celular neoplásica. Sus efectos en el proceso de neovascularización de los ccRCC han sido poco estudiados. Métodos: Estudiamos a través de un estudio morfométrico semiautomático e inmunohistoquímico, la densidad microvascular (MVD) y la expresión de factores angiogénicos en 124 pacientes con ccRCC de regiones…

Abnormal peripubertal development of the rat mammary gland following exposure in utero and during lactation to a mixture of genistein and the food co…

2012

The impact of early exposure to endocrine disruptor mixtures on mammary gland development is poorly known. Here, we identify the effects of a conception to weaning exposure of rats to the phytoestrogen genistein (G) and/or the antiandrogen vinclozolin (V) at 1 mg/kg-d, alone or in association. Using several approaches, we found that G- and GV-exposed rats displayed significantly greater epithelial branching and proliferation, wider terminal end buds than controls at PND35, as well as ductal hyperplasia and periductal fibrosis. Focal branching defects were present in V-exposed rats. An increased ER and AR expression was observed in G- and CV- as compared to V-exposed rats at PND35. Surprisin…

Impact of information and in-home sensory exposure on liking and willingness to pay: The beginning of Fairtrade labeled coffee in France.

2015

This study was conducted to assess how the Fairtrade label interacts with the perception of intrinsic product characteristics on liking and purchase decisions and to estimate the evolution of this interaction after exposure to the coffees and/or exposure to ethical information. In a first session, 119 consumers gave liking scores for 2 regular and 2 Fairtrade coffees under a blind tasting condition. Then, they were asked to indicate the maximum price they would pay for each product in 2 auctions taking place under different information conditions. In the first auction, participants saw the packaging but did not taste the coffee; in the second auction, they could both taste the coffee and se…

Association between Asthma Control and Exposure to Greenness and Other Outdoor and Indoor Environmental Factors: A Longitudinal Study on a Cohort of …

2022

Achieving and maintaining asthma control (AC) is the main goal of asthma management. Indoor and outdoor environmental factors may play an important role on AC. The aim of this longitudinal study was to evaluate the association between AC and exposure to greenness and other outdoor or indoor environmental factors in a cohort of asthmatic children. This study involved 179 asthmatic children (5–16 years). Parents were interviewed through a modified version of the SIDRIA questionnaire. AC was assessed at each visit. Exposure to greenness was measured using the normalized difference vegetation index (NDVI). A logistic regression model was applied for assessing risk factors for uncontrolled…

Psychobiological effects of perinatal exposure to odorants in mice. Part II: Behavioural alteration

2010

Early exposure to odorants pre-, post- or transnatally is known to. result in a decreased avoidance or increased preference for these. odorants in mammals. There are also indications that olfactory sensitivity. for these odorants can be affected. We exposed C57-Bl/6. mice of Mor23-GFP and M71-GFP lines to lyral (LY) or acetophenone. (AC), respectively, either transnatally through the water of the. mother (1*10-5 M) or postnatally in air for 1 hr per day (20 ll pure). Animals were weaned on postnatal day 20 (P20), and 3 tests were. performed:. 1) A 3-min exploration test on P20 in a rectangular arena presenting. LY and AC under a wire mesh to measure the time spent in each. half of the arena…

Frame fungi on insulated windows.

1985

Insulated windows (fixed triple glass window elements), became common in Finland during and after the energy crisis. Moisture tends to condense along the edges causing mold growth on the frames. Nine houses with insulated glass windows and eight with other types of window were studied. Fungus samples were taken from the window edges and from the inside air and cultivated on malt extract agar. In five of the houses with insulated windows there was visible mold growth on the window edges. The predominant fungus was Aureobasidium pullulans. With other types of windows there was only one case of visible mold. The concentrations of fungi were about the same in the air of houses with both types o…
