ABSTRACT
Abstract Flavonoids are a diverse class of polyphenolic substances largely found in plants including citrus peels and are reported to posess a variety of biological activities. We investigated important flavonoids apigenin, hesperidin, narigin, quercetin and tangeritine against diabetes and associated conditions. In current project drug likeness, ADMET analysis, molecular docking and in vitro assays were performed. The apigenin, quercetin and tanagretin exhibited compliance with Lipinski's rule of five. The molecular docking analysis showed best fit in transcriptional regulator 3TOP and 1IK3 in all tested compounds. During antioxidant assays, all flavonoids presented excellent activities. In the α-glucosidase assay, quercetin showed highest inhibition (76% at final concentration of 52 µg/ml) followed by tangeritin (73% at final concentration of 52 µg/ml). In case of 15-Lox assay, highest inhibition was seen in case of quercetin (75%) followed by apigenin (53%). In the AGEs assay, the quercetin showed 47% inhbition of protein cross link formation preceeded by the tenegretin exhited 37% inhibition. It was therefore concluded that tested flavonoids have significant activities in both in silico and in vitro models that is mainly due to differences in structural features and polar surface area.
ABSTRACT
Objective: A recent trend in diagnosis of oral cancer in young age is observed, however its impact on various clinicopathological parameters needs to be explored. The aim of the current study was to compare and analyze impact of age at diagnosis with clinicopathological parameters of oral squamous cell carcinoma patients
Methods: In this cross sectional study conducted at Department of Oncology Ziauddin Hospital Karachi, we included histologically confirmed cases of oral squamous cell carcinoma. The patients were categorized as young age group [40yrs and younger] and old age group [41 yrs and above]. A total of 115 patients diagnosed between 2013 and 2016 were enrolled in the study. The variables considered were age at diagnosis, sex, site of lesion, positive family history, tumor grade, stage, uric acid level and survival
Results: A statistically significant difference was observed between two age groups in overall survival, uric acid level and positive family history of cancer. No significant difference was observed in tumor location, grade and stage
Conclusion: Majority of oral cancer patients present at an advanced stage irrespective of age at diagnosis but young age has an overall improved survival. Moreover, a positive family history of cancer in young age group mandates further exploration of possible role of genetic polymorphisms which might be responsible for early onset of the disease
ABSTRACT
Temporary epicardial pacing wires [TEPWs] are commonly used during cardiac surgery to meet unforeseen complications like heart blocks or asystole. These are generally considered to be safe. The incidence of major complications with their use is low, but could be life threatening. Complications can be divided into those encountered during placement, removal, or retention of temporary epicardial pacing wires. We report a rare case of prosthetic mitral valve endocarditis caused by TEPWs that migrated into the pulmonary artery, presenting 5 months following mitral and aortic valve replacement surgery that required percutaneous removal of these temporary pacing wires via a right femoral vein approach. This case highlights the fact that delayed complications can rarely occur due to retained TEPWs and may have serious consequences. This fact should be taken into account when the strategy on dealing with such wires following cardiac surgery is determined. Routine retention of temporary epicardial pacing wires is not recommended
