Polyglycerol polyricinoleate (PGPR, E-476) is a powerful water-in-oil emulsifier 1–5 used to manufacture stable pan release agents for the bakery industry and to stabilize low fat margarine systems with high water content. However, its main application is in the chocolate and confectionery industry,6,7 since it improves the flow properties of chocolate and vegetable fat coatings by lowering the...

Traumatic peripheral nerve injuries constitute a huge concern to public health. Nerve damage leads decrease or even loss of mobility the innervated area. Adult stem cell therapies have shown some encouraging results and been identified as promising treatment candidates for regeneration. A major obstacle that approach is securing sufficient number cells at injured site produce measurable therape...

Water-soluble perylene tetracarboxylic acid bisimides (PBIs) with terminally linked polyglycerol dendrons of four different generations have been synthesized. These PBI dyes reveal a strong dendritic effect, enabling outstanding fluorescence quantum yields in water up to almost 100% for the highest dendron generation.

Abstract Superparamagnetic Iron Oxide Nanoparticles (SPIONs) are widely used in various areas of the biomedical field: for diagnosis (Magnetic Resonance Imaging), therapeutic applications (hyperthermia, nanovectorization). These require a good stability water and no aggregation SPIONs, with well-controlled physicochemical magnetic properties. In this work, SPIONs functionalized by citrate ligan...

The current epidemic of infections caused by antibiotic-resistant gram-positive bacteria requires the discovery of new drug targets and the development of new therapeutics. Lipoteichoic acid (LTA), a cell wall polymer of gram-positive bacteria, consists of 1,3-polyglycerol-phosphate linked to glycolipid. LTA synthase (LtaS) polymerizes polyglycerol-phosphate from phosphatidylglycerol, a reactio...

Abstract Magnetic particle imaging (MPI) quantitatively visualizes in vivo superparamagnetic iron oxide nanoparticles (SPIONs), which has shown great promises biomedicine. In this paper, we propose a single harmonic-based narrowband MPI approach via measuring harmonic—3 f 0 harmonic—of the SPIONs induced an excitation magnetic field with frequency = 5 kHz. The scanner is built to scan field-fre...

Polyglycerol monolaurates are generally recognized as safe food additives and commonly used emulsifiers. In this study, the antimicrobial effect of four polyglycerol on two Gram-positive bacteria (Staphylococcus aureus Bacillus subtilis) Gram-negative (Escherichia. coli Pseudomonas aeruginosa) were investigated. The minimum inhibitory concentration (MIC) diglycerol monolaurate (PG2ML), triglyce...

Wearing face masks during pandemics is an important protective measure against the spreading of virus-related infectious diseases. Nevertheless, risk indirect transmission virus by handling one earliest concerns. This problem can be minimized supplementing masks’ textile structure with coatings. Therefore, in this concept, suitable techniques for manufacturing filter media should evaluated. In ...

A stable magnetic nanocomposite of collagen and superparamagnetic iron oxide nanoparticles (SPIONs) is prepared by a simple process utilizing protein wastes from leather industry. Molecular interaction between helical collagen fibers and spherical SPIONs is proven through calorimetric, microscopic and spectroscopic techniques. This nanocomposite exhibited selective oil absorption and magnetic t...
