Background: In current study, chemical composition and antibacterial activity of leaves and flowers essential oils of Origanum vulgare ssp. gracile against four food-borne pathogens including  Escherichia coli, Listeria monocytogenes, Salmonella thyphimurium and Staphylococcus aureus were examined. Methods: The different organs (leaves and flowers) of O. vulgare ssp. gracile were har...

In this letter, we design a resource allocation algorithm for communications in millimeter wave (mmWave) multicast systems adopting multiple unmanned aerial vehicle (UAV)-borne intelligent reflecting surfaces (IRSs). Considering the effect of blockages buildings, jointly optimize placement UAVs and beamforming at ground base station (BS) passive UAV-borne IRSs maximizing minimum rate user clust...

Characterizing the basic reproduction number, R(0), for many wildlife disease systems can seem a complex problem because several species are involved, because there are different epidemiological reactions to the infectious agent at different life-history stages, or because there are multiple transmission routes. Tick-borne diseases are an important example where all these complexities are broug...

An important epidemiological consequence of aggregated host-parasite associations occurs when parasites are vectors of pathogens. Those hosts that attract many vectors will tend to be the focus of transmission. But to what extent, and can we identify characteristics of these key hosts? We investigated these questions with respect to the host-tick relationship of the yellow-necked mouse, Apodemu...

In view of the increasing demand of value added herbal products, an attempt was made to produce a functional fermented Aloe vera based herbal wine. The wine was evaluated for effect on probiotics and food borne pathogens. Aloe vera gel, supplemented with sugar proved to be a good medium for the growth of Saccharomyces cerevisiae for making the Aloe vera wine. The wine was found to be similar to...

In the emerging issue of increased multi-resistant properties in foodborne pathogens, silver nano particles are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of Nano Colloidal Silver towards food-borne pathogens such as Escherichia coli O157:H7, Listeria monocytogenes, Salmonella enterica Serovar Ty...

o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...

Paenibacillus sp. strain B2, isolated from the mycorrhizosphere of Sorghum bicolor and having an antagonistic activity towards soil-borne fungal pathogens, possessed extracellular cellulolytic, proteolytic, chitinolytic and pectinolytic enzyme activities. The eventual role of these lytic enzymes in cellular interactions between Paenibacillus sp. strain B2 and Phytophthora parasitica and Fusariu...
