Current Scientific Research and Innovations in Bulgarian Foods of Animal Origin
Author(s): Stefan Dragoev, Desislav Balev, Desislava Vlahova-Vangelova, Nikolay Kolev, Plamen Saraliyev, Anastasia Yankova, Nevena Nacheva Dimitrova, Kaloyan Kisov, Victoria DoychevaKeywords: current research, innovations, technological tendencies, meat, poultry, fish, sausagesAbstract: The article presents a critical review of current research and innovations in Bulgarian foods of animal origin over the last decade. It was presented new functional meat products enriched with biologically active components; inhibition of lipid peroxidation in traditional meat with reduced nitrite content; creation of an fish edible alginate coating enriched by a powder extract of distilled rose petals; in vivo experiment on diet supplementation of farm animals and poultry by phytonutrients; male layer-type chickens-an alternative source for high quality poultry meat; improvement of poultry quality by feeding with alternative insect protein sources; ultra-rapid super chilling of fish; acoustically assisted freezing of duck liver; radiofrequency treatment of modified atmosphere packaged meat products; utilization of egg by-products in dry feed ovalbumin; a comparative analysis of Bulgarian linden honey. It was concluded that dozens of new technologies and innovations related to foods of animal origin have been developed at the University of Food Technologies which are in line with global trends.

Design and Applications of Novel Antibacterial Agents Based on Chimeric Antisense Oligonucleotides as a New Rational Approach to Antibiotics Development
Author(s): Robert Penchovsky, Nikolet PavlovaAbstract: In recent decades, antibiotic resistance (AR) has emerged as a significant challenge for modern medicine, driven by the emergence of pathogenic bacterial strains resistant to all known antibiotics [1]. The mortality caused by resistant bacterial strains is increasing, underscoring the need to develop new antibiotics. We have created a series of antisense oligonucleotides (ASOs) that inhibit the growth of human pathogenic bacteria, serving as novel antibacterial agents. The ASOs are designed to bind specifically to riboswitches that are found in the genomes of almost all human pathogenic bacteria. Most bacterial riboswitches are located in the 5′-untranslated region (5′-UTR) of messenger RNAs (mRNAs) [2]. Most of them function as cis-acting allosteric elements that control the expression of genes essential to bacteria. To date, no riboswitches have been identified in the human genome, making them a suitable target for the development of new antibacterial agents. Riboswitches regulate the synthesis of vital cellular metabolites in various pathogenic bacteria via negative feedback: they bind directly to the final metabolite of the biosynthetic pathway. Gene expression is controlled at the levels of transcription and translation. Using riboswitches, we are developing innovative strategies to create new antibacterial agents that can also be applied against antibioticresistant bacteria [3-7]. That contributes to the development of more effective methods for developing new antibacterial agents. The design of ACOs is based on a purely bioinformatic analysis, in which their nucleotide sequences are precisely determined for specific binding to the target riboswitch [8, 9]. ACOs are chemically modified to increase their efficiency and resistance to cellular nuclease enzymes. ACOs are linked to a cell-penetrating peptide (CPP), which enables them to penetrate both Gram-negative and Gram-positive bacteria, as well as eukaryotic cells. In addition to the rational design of ACOs, we select specific riboswitches and other mRNAs as targets solely based on rational bioinformatic criteria [10].

The Correspondence of Raina Popgeorgieva to and from Moscow (1876 – 1879) in a Facsimile Edition
Author(s): Iveta RashevaKeywords: Raina Popgeorgieva, letters, conclusionsAbstract: This article presents the book “The Unknown Letters of Raina Popgeorgieva”, in which I. Rasheva published 33 letters received from Raina Knyaginya during her stay in Moscow. It is also dedicated to the life of Raina Popgeorgieva in Moscow, in the period from 1876 to 1879. The conclusions in it are based on the correspondence, and the letters are stored in the Bulgarian historical archive of the National Library in Sofia.
