Synthesis and characterization of modified chitosan as a promising material for enterosorption of heavy metal ions.

Currently, an important ecological problem is environmental pollution and its negative impact on living organisms, the consequences of which are deterioration in general health and the manifestation of various diseases, poisoning, endo- and exotoxicosis. Enterosorption method was proposed as a promising method for removing toxic substances from the living organisms using enterosorbents which can absorb various toxic substances of endogenous and exogenous nature in the lumen of the gastrointestinal tract. It has been proposed to use polymer-containing enterosorbents for eliminating of heavy metals from the organism.

Integrating the latest biological advances in the key steps of a food packaging life cycle.

This literature review provides a focus on the potential of integrating the latest scientific and technological advances in the biological field to improve the status of the key steps of a food packaging life cycle: production, usage, post-usage, and long-term fate. A case study of such multi-biological food packaging is demonstrated based on the use of PHAs (polyhydroxyalkanoates) polymer, a microbiologically produced polymer from non-food renewable resources, activated by the use of bioactive components to enhance its usage benefits by reducing food loss and waste, displaying potential for reusability, compostability as post-usage, and finally, being ultimately biodegradable in most common natural conditions to considerably reduce the negative impact that persistent plastics have on the environment. We discuss how designing safe and efficient multi "bio" food packaging implies finding a compromise between sometimes contradictory functional properties.

INVESTIGATION OF ALCOHOL DEHYDROGENASE (ADH3) GENE POLYMOPHISM IN PATIENTS WITH CHRONIC ALCOHOLIC PANCRATITIS IN AZERBAIJAN POPULATION.

The aim of the study is to determine the single nucleotide polymorphism of the ADH3 gene, which is involved in the development of chronic alcoholic pancreatitis in the Azerbaijani population. Seventy patients (51 with chronic alcoholic pancreatitis, 19 with chronic non-alcoholic pancreatitis) and 90 healthy individuals (55 smokers and 35 non- drinkers) were included in the study. Genomic DNA was isolated from venous blood based on the kit protocol.

Replica sizing strategy for aortic valve replacement improves haemodynamic outcome of the epic supra valve.

Objectives: Current sizing strategies suggest valve selection based on annulus diameter despite supra-annular placement of biological prostheses potentially allowing placement of a larger size. We assessed the frequency of selecting a larger prosthesis if prosthesis size was selected using a replica (upsizing) and evaluated its impact on haemodynamics.

Methods: We analysed all discharge echocardiograms between June 2012 and June 2014, where a replica sizer was used for isolated aortic valve replacement (Epic Supra: 266 patients, Trifecta: 49 patients).
