Antiviral Activity of Beebread, Bee-Collected Pollen and Artificially Fermented Follen against Influenza A Virus.

Bee-collected pollen (BCP) and the naturally fermented BCP product known as bee bread (BB) are functional foods renowned for their nutritious, antioxidant, antibacterial and other therapeutic properties. This is the first study employed to assess the antiviral activity of BCP and BB against influenza A virus (IAV) H1N1 along with their proteinaceous, aqueous and -butanol fractions. Additionally, artificially fermented BCP has been evaluated against IAV (H1N1).

Antiviral Activity of Bee Products.

Honey bees provide many products exerting a wide range of benefits to humans. Honey, propolis, royal jelly, beeswax, bee venom, bee pollen and bee bread have been used as natural medicines since ancient times because of their therapeutic effects. These products have demonstrated healing properties against wounds, diabetes, gastrointestinal diseases, cancer, asthma, neurological diseases, bacterial and viral infections.

Physicochemical Characterization and Biological Properties of Pine Honey Produced across Greece.

Pine honey is a honeydew honey produced in the East Mediterranean region (Greece and Turkey) from the secretions of the plant sucking insect (Gennadius) (Coccoidea: Marchalini-dae) feeding on living parts of species. Nowadays, honeydew honey has attracted great attention due to its biological activities. The aim of this study was to study unifloral pine honey samples produced in Greece regarding their physicochemical parameters and antioxidant and antibacterial activity against five nosocomial and foodborne pathogens.

Biological Properties of Bee Bread Collected from Apiaries Located across Greece.

Bee bread is the only fermented product of the beehive. It constitutes the main source of proteins, lipids, vitamins, and macro- and microelements in honeybee nutrition and it exerts antioxidant and antimicrobial properties, though research on these aspects has been limited so far. In this study 18 samples of Greek bee bread, two of which were monofloral, were collected during different seasons from diverse locations such as Crete and Mount Athos and were tested for their bioactivity.

Transcriptomic Analysis of Response to Pine Honey via RNA Sequencing Indicates Multiple Mechanisms of Antibacterial Activity.

Pine honey is a unique type of honeydew honey produced exclusively in Eastern Mediterranean countries like Greece and Turkey. Although the antioxidant and anti-inflammatory properties of pine honey are well documented, few studies have investigated so far its antibacterial activity. This study investigates the antibacterial effects of pine honey against .

Antimicrobial Activity of Bee-Collected Pollen and Beebread: State of the Art and Future Perspectives.

Bee-collected pollen (BCP) is a well-known functional food. Honey bees process the collected pollen and store it in the hive, inside the comb cells. The processed pollen is called bee- bread or ambrosia and it is the main source of proteins, lipids, vitamins, macro-and micro-elements in honey bee nutrition.

Association of p16 (CDKN2A) polymorphisms with the development of HPV16-related precancerous lesions and cervical cancer in the Greek population.

The tumor suppressor protein p16 plays a fundamental role in cell cycle regulation and exerts a protective effect against tumor growth. Two different polymorphisms at positions 540 and 580 at the 3'UTR of exon 3 of p16 gene are implicated in several types of cancer, while their role in cervical cancer development remains rather vague. In the present study, we investigated for the impact of p16 genotypes/haplotypes on patients' vulnerability to cervical disease and examined whether these factors can be used as progression markers in the Greek population.

Intra- and inter-serotypic recombinations in the 5΄ UTR-VP4 region of Echovirus 30 strains.

Recombination has been recognized as a major mechanism of evolution in enteroviruses. The Echovirus 30 (E-30) strain Gior was sequenced and phylogenetically compared to all available E-30 sequences to detect recombination events between the 5΄UTR and VP1 genomic regions. The comparison of phylogenetic trees of the 5΄UTR and VP1 revealed incongruences concerning strains, lineages and sub-lineages.

Association of codon 72 polymorphism of p53 with the severity of cervical dysplasia, E6-T350G and HPV16 variant lineages in HPV16-infected women.

Polymorphic variability in the tumour-suppressor protein p53 at codon 72 has a considerable impact on cervical cancer development. The present study clarified the association between p53 codon 72 genotypes and the risk of cervical disease in Greek patients. We also examined whether the presence of specific p53 genotypes in combination with HPV16 variants or E6 T350G sequence variation can modify an individual's susceptibility to cervical disease.

Serum Neutralization Assay for the Determination of Antibody Levels Against Non-Polio Enterovirus Strains in Central and Western Greece.

Mutations and recombination events have been identified in enteroviruses. Point mutations accumulate with a frequency of 6.3 × 10(-4) per base pair per replication cycle affecting the fitness, the circulation, and the infectivity of enteroviral strains.

Molecular epidemiology and evolutionary dynamics of Echovirus 3 serotype.

Echovirus 3 (E3) serotype has been related with several neurologic diseases, although it constitutes one of the rarely isolated serotypes, with no report of epidemics in Europe. The aim of the present study was to provide insights into the molecular epidemiology and evolution of this enterovirus serotype, while an E3 strain was isolated from sewage in Greece, four years after the initial isolation of the only reported E3 strain in the same geographical region. Phylogenetic analysis of the complete VP1 genomic region of that E3 strain and of those available in GenBank suggested three main genogroups that were further subdivided into seven subgenogroups.
