IMPACT OF OXIDATIVE STRESS IN THE PATHOGENESIS OF CERVICAL CANCER THERAPEUTIC APPROCHES

Cervical cancer (CC) is acknowledged as the most ubiquitous carcinoma among females along with the utmost prevalence in developing nations. The major cause of CC is HPV exposure, especially HPV16 and 18. Inflammation is linked to the carcinogenesis of CC in addition to HPV infection. Although the precise cause of CC is yet unknown, using oral contraceptives, being immunosuppressed, and smoking may enhance the risk of the disease. Oxidative stress (OS), in addition to HPV, is linked to cervical cancer. Across several clinical and preclinical research, the dysfunctional redox system and the impact of oxidative stress throughout the aetiology of CC have been examined. Redox homeostasis must therefore be maintained, which calls for both enzymatic and nonenzymatic redox regulators. In this study, we explored the therapeutic strategies used to preserve redox balance, lower cervical cancer mortality, and illustrate the contribution of oxidative stress in the aetiology of the disease

ROLE OF REAL TIME PCR (RT-PCR) IN CLINICAL DIAGNOSIS FOR COVID-19 REVIEW

The pandemic of Coronavirus Disease 2019 (COVID19) has compelled scientists to create highly reliable diagnostic tools quickly in order to successfully and properly diagnose this pathology and thereby prevent infection transmission. Even though structural and molecular properties of the severe acute respiratory syndrome coronavirus 2 (SARSCoV2) were previously unknown, private research institutes and biomedical firms quickly developed numerous diagnostic procedures beneficial for making a correct detection of COVID19. Rapid antigen or antibody testing, immunoenzymatic serological tests, and RT-PCR based molecular assays are the most frequently used and validated procedures now available. The PCR has grown in popularity in molecular diagnostics to the point where it is still considered the gold standard for finding nucleotides from a variety of sources becoming an indispensable tool in the research lab. Because of its improved speed, sensitivity, reproducibility, and lower likelihood of carry-over contamination, real-time PCR has gained greater popularity. Currently, five different chemistries are employed to detect PCR product during real-time PCR. The self- fluorescing amplicons, DNA binding fluorophores, 5? endonuclease, neighbouring linear and hairpin oligoprobes, and self-fluorescing amplicons are all detailed in depth. We also go through the problems that have hampered the development of multiplex real-time PCR and the importance of real-time PCR in nucleic acid quantification.
