Article Synopsis
- The study aimed to evaluate the effectiveness of orbital lesion diagnoses by comparing findings from external radiologists to those from a specialized in-house radiologist, correlating these with final histopathological results.
- A retrospective review of 40 patients' imaging over 7 years showed a significant difference in accuracy, with the in-house radiologist achieving a 95% accuracy rate, compared to just 50% for extramural radiologists.
- The in-house radiologist also demonstrated much higher sensitivity and positive predictive values for both benign (93.31% sensitivity) and malignant lesions (95.24% sensitivity), indicating that specialized training improves diagnostic performance.
A series of new water soluble nickel(II) complexes containing triphenylphosphine and 4-methoxysalicylaldehyde-4(N)-substituted thiosemicarbazones were synthesized and characterized. Crystallographic investigations confirmed the structure of the complexes (1-4) having the general structure [Ni(4-Msal-Rtsc)(PPh)] (Where R=H (1); CH (2); CH (3); CH (4)) which showed that thiosemicarbazone ligands coordinated to nickel(II) ion as ONS tridentate bibasic donor. DNA/BSA protein binding ability of the ligands and their new complexes were studied by taking calf-thymus DNA (CT-DNA) and Bovine serum albumin (BSA) through absorption and emission titrations.
