The purpose of this study was the antimicrobial functionalization of paper pulp with natural biopolymer chitosan. Laboratory paper sheets were prepared for this purpose from paper pulp with incorporated chitosan. The prepared paper sheets were analysed regarding amino group content, mechanical properties and hydrophilicity. All of these parameters are important for hygienic applications of pape...

The skins and seeds of grapes are known to be rich sources of phenolic compounds, both flavonoids and non-flavonoids. The aim of the present study is to determine polyphenolic composition, antioxidant potential along with free radical scavenging activity and antimicrobial properties of ethanol extract of Grape skin and seed. Grape seed showed high antioxidant and antimicrobial activity compared...

Treatments of bacterial infections have become a difficult task in the medical practice due to high level of resistance to the existing marketed antibiotics. This problem evoked us to search for new antimicrobial agent for better management of bacterial infections. The present study was carried out to evaluate antimicrobial properties of epidermal mucus (soluble mucin or s-mucin). s-mucin was e...

Antimicrobial peptides are widespread in living organisms and constitute an important component of innate immunity to microbial infections. By the early 1980s, more than 800 different antimicrobial peptides had been isolated from mammals, amphibians, fish, insects, plants and bacterial species. In humans, they are produced by granulocytes, macrophages and most epithelial and endothelial cells. ...

In last decade, the uncontrolled use of antibiotics as growth promoter for livestock has led to the appearance of antibiotic-resistant pathogens and increased risk of infectious diseases. This situation has triggered intensive research efforts to find safe alternative strategies. Certainly, the plants and vegetables and their derivatives as natural safe substances could be good candidates in th...

background: this study aimed at investigation of the chemical composition, antimicrobial activity, and antioxidant properties of clove, cumin, origanum, and anise essential oils (eos). methods: chemical compositions of the eos were identified using gas chromatography/mass spectrometry (gc/ms). the antibacterial activities of eos against four important food-borne bacteria were assessed by disc d...

To design new antimicrobial peptides, we have focused on various proteins which are not essential for self-defense but carry important responsibilities for biosystems. Previously, we reported that highly efficient antimicrobial properties or antiviral properties are inherent in the nuclear translocation signals and binding sites on laminin receptors. Here we introduce microtubule binding sites ...

Antimicrobial polymers are an attractive alternative to low molecular weight biocides, because they are non-volatile, chemically stable, and can be used as non-releasing additives. Polymers with pendant quaternary ammonium groups and hydrophobic chains exhibit antimicrobial properties due to the electrostatic interaction between polymer and cell wall, and the membrane disruptive capabilities of...

Vertebrate secreted RNases (ribonucleases) are small proteins that play important roles in RNA metabolism, angiogenesis or host defence. In the present study we describe the antimicrobial properties of the N-terminal domain of the hcRNases (human canonical RNases) and show that their antimicrobial activity is well conserved among their lineage. Furthermore, all domains display a similar antimic...

The emergence of bacterial strains resistant to antibiotics is a general public health problem. Progress in developing new molecules with antimicrobial properties has been made. In this study, we evaluated the biological activity of a hybrid nanocomposite composed of synthetic biomimetic hydroxyapatite surface-functionalized by lactoferrin (LF-HA). We evaluated the antimicrobial, anti-inflammat...
