Objectives: Coronary artery disease (CAD), also known as ischemic heart disease or atherosclerotic cardiovascular disease (CVD), is one of the major causes of morbidity and mortality globally and has contributed to about 80% of sudden deaths. There have been advancements in the diagnosis and treatment of CAD, some of which are still going on to improve patient care, however, there is a dearth of information regarding the various challenges the patients go through after being diagnosed with CAD and so a qualitative study was conducted on cardiac patients in Mauritius to shine a light on the various aspects of life affected by CAD. This is the first qualitative study conducted on cardiac patients in Mauritius. Material and Methods: A phenomenological qualitative study was performed on 12 patients who were diagnosed with CAD, at the Cardiac Unit of Victoria Hospital, Mauritius. By the use of NVivo 12 (Windows) Plus software, after it was transcribed, codes/nodes and themes were generated. Results: Twenty-five different codes were inferred from the study done and from the respective codes, eight main themes were established. The main themes drawn from the study were as follows: Emotional factors, risk factors, optimistic factors, support, awareness of your health, consequences, lifestyle modifications, and the healthcare system. Conclusion: An event of CAD is an experience with multifaceted influences on innumerable aspects of the patient’s life. The study illuminated the immense sufferings and emotional bearings of those patients who were living with heart disease. They expressed their overbearing, insecurities, and a loss of control over various aspects of their lives. This study provided various thought-provoking themes that emerged after transcribing the qualitative interviews. It also highlighted the various challenges faced by patients and how the beliefs of patients with CAD were vital to sustaining them. Family support is a vital aspect in keeping the patient both motivated to follow their treatment and emotionally grounded.

The research discusses the use of flashes of ultraviolet-C rays in inducing resistance against viral pathogens and the possibility of its employment in covered houses or garden nurseries. A number of tomato and tobacco plants of type Nicotiana tabacum, uder protected cultivation conditions, were exposed to UV-C rays at wavelengths 200-280 nm using an electronic LED lamp, for 5 and 10 minutes, all plants were inoculated 48 hours after the last exposure to UV rays. The number and size of local lesions were calculated on the leaves of inoculated tobacco plants, as well as monitoring the development of symptoms on tomato plants inoculated with the virus for 12 days of inoculation, and the virus concentration was estimated based on the amount of absorbance at 405 nm by ELISA test. The results indicated that the ultraviolet rays used enhanced the plant's resistance to viral infection through a noticeable increase in the enzyme peroxidase, as it reached (59220 nanometers) in the treated plants compared to the untreated plants that were (28,016 nanometers). The irradiation for the first five minutes had a higher effect than the longer irradiation that lasted for ten minutes, in addition to that the irradiation for intermittent periods and for a short period was better than the continuous exposure for one time. It was found that the leaves far from the radiation exposure area acquired an inducible character of resistance against the pathogen.
