The use of social control to produce more cooperative behaviors may positively influence road use and safety. This study uses an online questionnaire to test how eyes images affect the behavior of pedestrians when crossing a road. Different eyes images of men, women and a child with different facial expressions -neutral, friendly and angry- were presented to participants who were asked what they would feel by looking at these images before crossing a signalized road. Participants completed a questionnaire of 20 questions about pedestrian behaviors (PBQ). The questionnaire was received by 1,447 French participants, 610 of whom answered the entire questionnaire. Seventy-one percent of participants were women, and the mean age was 35 ± 14 years. Eye images give individuals the feeling they are being observed at 33%, feared at 5% and surprised at 26%, and thus seem to indicate mixed results about avoiding crossing at the red light. The expressions shown in the eyes are also an important factor: feelings of being observed increased by about 10-15% whilst feelings of being scared or inhibited increased by about 5% as the expression changed from neutral to friendly to angry. No link was found between the results of our questionnaire and those of the Pedestrian Behavior Questionnaire (PBQ).

Saliva samples were obtained and cultivated to isolate, identify, and calculate the viable colony count of <i>C. albicans</i> in (cfu/ml). In contrast, serum levels of iron and ferritin were quantified using chemical analyzers.</p><p><strong>Result: </strong>Showed that 73.33% of thalassemia major group exhibited oral <i>C. albicans</i> colonization, which is significantly higher than that of thalassemia minor group 40% and control group 6.67%. Biochemical analyses revealed significantly higher iron 278.82 μg/dl and ferritin 2783.80 ng/ml levels in major group p<0.001 when compared with both thalassemia minor group 122.652 μg/dl, 74.723 ng/ml and control groups 127.438 μg/dl and 63.150 ng/ml respectively. <i>C. albicans</i> colony count in saliva was significantly elevated in beta-thalassemia major, as compared with beta-thalassemia minor group and control group.</p><p><strong>Conclusion: </strong>Findings suggest that iron overload, which results from recurrent blood transfusions and causes immune dysfunction, contributes to higher risk of oral fungal infections in Beta-thalassemia patients compared with controls.</p>","PeriodicalId":12260,"journal":{"name":"F1000Research","volume":"14 ","pages":"555"},"PeriodicalIF":0.0,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12351238/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144872125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
