Abstract Polyetheretherketone (PEEK) is a semi‐crystalline thermoplastic polymer that has been gradually used in the repair of bone defects because its well chemical stability, reliable biocompatibility, excellent X‐ray radiolucency, and low modulus. However, PEEK biologically inert material, planktonic bacteria can adhere to surface eventually form biofilms, allowing for rapid development impl...

Separation and identification of antibacterial chamomile components 2 Abstract Components of 50% ethanolic chamomile (Matricaria recutica L.) flower extract, previously found antibacterial in a TLC-bioautographic study, were separated and isolated by the use of on-line OPLC, which consisted of an OPLC 50 BS system, an on-line coupled flow-through UV detector, and a manual fraction collector. Th...

Essential oils are concentrated liquids of intricate combinations volatile substances, extracted from various plant parts. Several bioactive substances with antibacterial and antioxidant activities abundant in essential oils. Some have also been employed medicine. Due to the risk associated employing synthetic preservatives, use as natural additives for extending shelf life food products has dr...

Natural food preservation method refers to application of naturally produced antimicrobial compounds that are obtained from plants, animals and microbes to prevent food spoilages microorganism, proliferation and growth of food borne pathogens in food and foods products. Now it is the time of growing interest of many researchers with the application of these natural antimicrobial compounds as sa...

Background: Natural substances that were initially obtained from plants once regarded as a beneficial source of possible medicinal agents and recognized crucial in the development human diseases. The current study sought to determine whether hydroalcoholic extracts Garcinia cambogia plant fruits included any bioactive substances. Materials Methods: collected, shade-dried, ground into fine powde...

Many of the plant species found that it can be used medically (Ali-Shtayeh and Abu, 1999). Essential oils are aromatic substances which are obtained from various plant parts by steam distillation; many of which exhibit antibacterial (Ozcan et al., 2006), antifungal (Chee and Lee, 2007) and antiviral (Khan et al., 2005) activity. Lemongrass (Cymbopogon citratus) is widely used in traditional med...

Background: Nature offers an incredible diversity of chemical compounds that boast a wide array of physiological effects. Many natural substances are employed in personal care products. Which of these natural substances are hazardous ingredients? How do European legal instruments regulate natural substances with toxic effects? Results: 1,358 natural substances appear in the ‘International Nomen...

Emergency food products (EFPs) or energy bars are used in critical situations, such as natural disasters, to promote crisis management. EFPs require sophisticated packaging strategies. Edible coatings incorporated with antimicrobial agents could be considered active materials for increasing EFP safety. In this study, pectin-based pomegranate peel extracts were protect bars. Initially, total phe...

Musca domestica L. (Diptera: Muscidae), the housefly, exhibits unique immune defenses and can produce antibacterial substances upon stimulation with bacteria. On the basis of the cDNA library constructed using the suppression subtractive hybridization method, a 1188-bp antibacterial substance gene, which we named AS566, was amplified by rapid amplification of cDNA ends from M. domestica larva s...

The spread of multidrug-resistant strains of fungus and the reduced number of drugs available, makes it necessary to discover new classes of antifungals and compounds that inhibit these resistant mechanisms. This has led to a search for therapeutic alternatives, particularly among medicinal plants and compounds isolated from them used for their empirically antifungal properties. In these natura...
