Aim: To evaluate the functional relationship between the nitric oxide synthase (NOS) and superoxide dismutase (SOD) enzymes in the pathogenesis of human senile cataract lenses of non-diabetic patients. Methods: Total solubilized proteins from human cataract lens were compared with normal lens (control) by 2-Dimenstional gel electrophoresis (2-DE). Proteins with different abundances were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Western blot analysis was used to verify the changes in expression of NOS3 and SOD2. A further functional association of NOS3 with SOD2 and other proteins was seen by STRING 8.3 databases. Results: In the 2-DE maps, the cataract and normal lens proteins migrated in the region of pH 3 - 10 with a relative molecular weight of 20 - 130 kDa. Approximately two protein spots with differential intensity were detected as NOS3 and SOD2 using MALDI-TOF-MS. Western blot analysis showed high expression of NOS3 in cataract and SOD2 in normal lens samples. String interaction network revealed strong interactions between NOS3 and SOD2 at high confidence score, which is helpful in characterization of functional abnormalities that may be a causative factor in the pathogenesis of cataract. Conclusion: This study will offer new avenues for mechanistic evaluation and future prevention of cataractogensis. However, large scale studies will be required to evaluate the effect of this interaction on the clinical outcome in human cataract.

Background: Negative and stigmatizing attitudes and behaviours towards people with mental health problems have the potential to lead to a lack of access to care, under-treatment, social marginalization, and can undermine the relationship between the patient and provider. The study aimed to measure attitude of healthcare professionals towards mental illness. Methods: Across sectional descriptive study was conducted over one month from April to May 2019 at Ras Al khaimah medical and health Science University and affiliated health care facilities. Mental Illness Clinicians’ Attitudes Scale version 4 Questionnaire was used to collect data from participants after obtaining their informed consent with assured confidentiality. Results: The study included 113 health care professionals. The mean score of attitude of health care professionals towards mental illness was 57.8 ± 10.8 out of 96. Negative attitudes were reported about the dangerousness, respect and suspicion over recovery of people with mental health problems, interactions with them in clinical practice, and fear of disclosure to colleagues or friends about mental health problems and confidence in capabilities of assessing mental health problems in primary care. The significant positive attitude was found among participants who were university faculty than those who worked in hospitals and Primary care centres (P = 0.04). Health care professionals who were university faculty and have reported more than 10 years of experience as health professionals reported significantly higher mean scores (P Conclusion: Educational programs might be useful to raise awareness towards the stigmatizing attitudes towards mental health and mental illnesses.
