A Dual Biomarker Approach to Stress: Hair and Salivary Cortisol Measurement in Students via LC-MS/MS.

Stress is a significant issue among students, affecting both their mental and physical health. In this study, we investigated cortisol levels, a key biomarker for stress, in students at the United Arab Emirates University (UAEU) during their exam period. Using a sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) methodology we measured cortisol concentrations in hair and saliva samples and explored the potential correlation between exam-induced stress and cortisol levels.

Design of a Microfluidic Photocatalytic Reactor for Removal of Volatile Organic Components: Process Simulation and Techno-Economic Assessment.

This study reports on a gas-phase photocatalytic microreactor (MR) employed for the degradation of 2-propanol in indoor air. A process flow diagram was developed and simulated in Aspen Hysys V10, and a techno-economic assessment was carried out based on the simulated results. An economic evaluation was carried out using a fixed and demand-dependent variable cost model.

Women's knowledge and attitude towards pregnancy in a high-income developing country.

Objective: The aim of this study was to determine the knowledge and attitudes among women in a high-income developing country regarding pregnancy and antenatal care.

Methods: Women who participated in the study were asked to complete a questionnaire. The questionnaire enquired about age, level of education, Internet use, marital status, and employment.

Interpretation of way-finding healthcare symbols by a multicultural population: navigation signage design for global health.

The interpretation of way-finding symbols for healthcare facilities in a multicultural community was assessed in a cross-sectional study. One hundred participants recruited from Al Ain city in the United Arab Emirates were asked to interpret 28 healthcare symbols developed at Hablamos Juntos (such as vaccinations and laboratory) as well as 18 general-purpose symbols (such as elevators and restrooms). The mean age was 27.

Health education materials for Arab patients: content and design preferences.

Objective: To investigate the content and design preferences of printed health education leaflets among Arab patients.

Materials And Methods: A survey questionnaire to 17 subjects (women: n = 8, men: n = 9; age range 17-70 years) and three focus-group discussions (total 16 participants) were used to assess preferences by showing samples of Arabic health education materials. The questionnaire was administered by interviewers.

The impact of image dynamic range on texture classification of brain white matter.

Background: The Greylevel Cooccurrence Matrix method (COM) is one of the most promising methods used in Texture Analysis of Magnetic Resonance Images. This method provides statistical information about the spatial distribution of greylevels in the image which can be used for classification of different tissue regions. Optimizing the size and complexity of the COM has the potential to enhance the reliability of Texture Analysis results.
