Third International Conference on

Natural bio-antioxidants as an inspiration for food chemistry and pharmacy

17-21 September, Nessebar, Bulgaria

Dear Colleagues,

On behalf of the Organizing Committee, it is great pleasure to announce the 3rd International Conference on Bio-antioxidants (BIO-ANTIOXIDANTS 2019), which will be held at Marieta Palace Hotel located on the Black Sea coast in Nessebar near Burgas, Bulgaria, from the 17th to the 21st of September 2019.

All young colleagues (young scientists, PhD students, students, pupils) are cordially welcome to participate also at the dedicated 3rd Young Scientists School on Bio-antioxidants (YSSBA 2019).

BIO-ANTIOXIDANTS 2019 aims to make an important contribution towards a better understanding the mechanism of action of natural bio-antioxidants and their synthetic analogues in physiological and pathological states that will lead to the development of new therapeutic and disease-preventive agents. Moreover, we will again discuss the role of bio-antioxidants as modulators of redox signaling.

Among the strategic topics, which BIO-ANTIOXIDANTS 2019 will be focused on are:

  • A. Oxidative Stress and Human Health
  • B. Natural Bio-antioxidants
  • C. Synthetic Analogues of Natural Bio-antioxidants
  • D. Homogeneous and Heterogeneous Lipid Oxidation
  • E. Food Analysis, Food Additives and Food Supplements
  • F. Advanced Methods for Analysis of Bio-antioxidants

Many leading scientist, but also several young investigators from all over the world (Bulgaria, Italy, Poland, Russian Federation, Spain, USA, etc.), whose research and practice are closely related and dedicated to the development and application of novel bio-antioxidants for prevention and therapy of clinically and socially important diseases related to the oxidative stress, are going to attend the conference and share their knowledge, both in scientific and clinical aspect.

We strongly believe that your participation will definitely enrich the conference and ensure its success and we look forward to welcoming you to Nessebar in September 2019.

Yours sincerely,

Prof. Dr. Vessela D. Kancheva
Chairperson of BIO-ANTIOXIDANTS 2019

Assoc. Prof. Dr. Petko Denev
Coordinator of YSSBA 2019

    There are numerous foreign exchange offices and ATMs around the city centre. It’s always prudent to carry a little foreign cash, however, in case you can’t find an ATM or bank office nearby. You can always change cash at the hotel, though the commission will be high.

    Make sure you have enough of the national currency when you plan to visit local markets and shops.

  • When a gratuity is not included in your bill, which is usually the case, 10% is customary. If service is outstanding, you could go as high as 15%. With taxi drivers, you usually just round up the sum if you have been happy with the ride or for the sake of convenience.

  • The climate in Bulgaria is moderate continental with beautiful blooming spring, dry and hot summer, long and pleasant autumn, and mild winter with lots of opportunity for skiing.
