Eco-friendly Fluorescent Sensor for Sensitive and Selective Detection of Zn2+ and Fe3+ Ions: Applications in Human Hair Samples.

A new eco-friendly sensor, 3-((6-((4-chlorobenzylidene)amino)pyridin-2-yl)imino)indolin-2-one (CBAPI) was synthesized and well characterized. The CBAPI sensor was employed for detecting Zn2+ and Fe3+ ions. It exhibited a low limit of detection at pH 6.0, with values of 2.90, for Zn2+ and 3.59 nmol L-1 for Fe3+ ions. The sensor demonstrated high selectivity over other interfering cations. Additionally, the high binding constants reflect the great affinity of sensor towards Zn2+ and Fe3+ ions. To further validate its quantification ability for Zn2+ ions, the synthesized CBAPI sensor was used to determine Zn levels in human hair samples, and the results were confirmed using atomic absorption spectroscopy (AAS). The AGREE metric tool was used to assess the method's environmental impact and practical applicability. These positive outcomes indicated that the new method for detecting Zn2+ and Fe3+ ions is environmentally friendly and safe for humans. The developed CBAPI sensor represents a potential development in metal ion detection, combining sensitivity, selectivity, and rapidity.

Knowledge, attitudes, and perceptions of the multi-ethnic population of the United Arab Emirates on genomic medicine and genetic testing.

INTRODUCTION: The adoption and implementation of genomic medicine and pharmacogenomics (PGx) in healthcare systems have been very slow and limited worldwide. Major barriers to knowledge translation into clinical practice lie in the level of literacy of the public of genetics and genomics. The aim of this study was to assess the knowledge, attitudes, and perceptions of the United Arab Emirates (UAE) multi-ethnic communities toward genomic medicine and genetic testing. METHOD: A cross-sectional study using validated questionnaires was distributed to the participants. Descriptive statistics were performed, and multivariable logistic regression models were used to identify factors associated with knowledge of genomics. RESULTS: 757 individuals completed the survey. Only 7% of the participants had a good knowledge level in genetics and genomics (95% CI 5.3-9.0%). However, 76.9% of the participants were willing to take a genetic test if their relatives had a genetic disease. In addition, the majority indicated that they would disclose their genetic test results to their spouses (61.5%) and siblings (53.4%). CONCLUSIONS: This study sets the stage for the stakeholders to plan health promotion and educational campaigns to improve the genomic literacy of the community of the UAE as part of their efforts for implementing precision and personalized medicine in the country.

Knowledge and Practice Concerning Breast Cancer Risk Factors and Screening among Females in UAE.

Breast cancer is considered the most dangerous cancer for women, driving the highest number of mortalities in women worldwide. According to the WHO 2020 report, breast cancer showed the highest five-year prevalence in the UAE, among other cancers. This research assessed breast cancer awareness, potential risk factors, screening approaches and practices, barriers to screening, and attitudes toward seeking medical help among UAE women. A cross-sectional community-based study was conducted through a web-based validated questionnaire. Data analysis was carried out using IBM SPSS version 27. The questionnaire was sent through social media platforms. The eligible completed were 616 responses. This study showed a prevalence of breast cancer of 3.1% among the study population. Regarding Breast cancer knowledge, most of the participants, 65.8% had moderate knowledge, 19% had poor knowledge, and only 7.6% had good knowledge. Breast cancer screening methods were the most recognized section at 76%, followed by knowledge of symptoms and while the least known section was the BC risk factors. Twenty-five percent of respondents had at least one breast cancer symptom. About 37.1% of women aged more than 40 years had never undergone mammography. In potential, most participants and 81.7% were having more than five of the BC risk factors had adequate knowledge about breast cancer with relatively higher knowledge scores for screening methods and symptoms. Participants who received information from healthcare providers or attended awareness events had a higher knowledge score. In contrast, insufficient mammography screening had been revealed. At the same time, potential risk evaluation revealed a high percentage of participants suffering from many potential risk factors.
