Metal Content, Fatty Acid and Vitamins in Commercially Available Canned Fish on the Bulgarian Market: Benefit-Risk Ratio Intake.

Today, the distribution and consumption of canned products have become widespread due to the convenience of using processed fish products. This study aims to evaluate elements of toxicological concern and essential elements (Cd, Al, Cu, Cr, Mn, Fe, Pb, Ni, and Zn), the fatty acid composition, and the fat-soluble vitamin and antioxidant pigment contents of various canned fish products purchased on the Bulgarian market. The estimated weekly intake and human health benefit-risk ratio based on metal elements and n-3 LC-PUFA contents in canned fish products were assessed.

Polyphosphoester-based Paclitaxel Complexes: Biological Evaluation.

Background: Polymer drug delivery systems designed to reduce systemic side-effects are clinically important. Polyphosphoesters are biodegradable polymers with versatile structure that could afford reactive sites or polar functions for drug immobilization.

Materials And Methods: The drug-polyphosphester systems were characterized by nuclear magnetic resonance and infrared spectroscopy, differential scanning calorimetry and dynamic light scattering.
