Pulmonary delivery of nucleic acids opens the possibility for direct treatment of lung diseases, like fibrosis, cancer, and infections. Lung retention and biodistribution of nucleic acids remain important issues for the development of suitable therapeutic approaches. Moreover, monitoring the dynamic biodistribution processes of siRNA after aerosol delivery can help in identifying bottlenecks and optimising therapeutic concepts. We investigated dynamic biodistribution events after intratracheal application of chemically stabilised siRNA labeled with near infrared emitting dye AlexaFluor750 (AF750)...

Two methods for the determination of Sudan dyes (Sudan I, Sudan II, Sudan III and Sudan IV) in food samples, by solid phase extraction - capillary liquid chromatography, are proposed. Both methods use nanocellulose (NC) extracted from bleached argan press cake (APC), as a nano-adsorbent recycled from an agricultural waste material. One of the methods involves the dispersion of NC in food sample extracts, along with the waste and eluents being separated by centrifugation. In the other method, NC was modified by magnetic iron nanoparticles before using it in the extraction of Sudan dyes...

The conduct of high-quality nutrition research requires the selection of appropriate markers as outcomes, for example as indicators of food or nutrient intake, nutritional status, health status or disease risk. Such selection requires detailed knowledge of the markers, and consideration of the factors that may influence their measurement, other than the effects of nutritional change. A framework to guide selection of markers within nutrition research studies would be a valuable tool for researchers. A multidisciplinary Expert Group set out to test criteria designed to aid the evaluation of candidate markers for their usefulness in nutrition research and subsequently to develop a scoring system for markers...

We report the feasibility of enterocin AS-48, a circular cationic peptide produced by Enterococcus faecalis, as a new leishmanicidal agent. AS-48 is lethal on Leishmania promastigotes as well as on axenic and intracellular amastigotes at low micromolar concentrations, with scarce cytotoxicity on macrophages. AS-48 induced a fast bioenergetic collapse of L. donovani promastigotes, but only a partial permeation of their plasma membrane with limited entrance of vital dyes, even at concentrations beyond its full lethality...

BACKGROUND: Experimental manipulations of floral nectar in food deceptive species can reveal insights into the evolutionary consequences of the deceptive strategy. When coupled to pollen tracking, the effects of the deceptive pollination syndrome on both male and female reproductive success may be quantified. Attraction of pollinators in deceit-pollinated species often relies on producing a conspicuous floral display which may increase visibility to pollinators, but in-turn may increase within plant selfing...

Protein aggregation, a characteristic of several neurodegenerative diseases, displays vast conformational diversity from amorphous to amyloid-like aggregates. In this study, we have explored the interaction of tartrazine with myoglobin protein at two different pHs (7.4 and 2.0). We have utilized various spectroscopic techniques (turbidity, Rayleigh light scattering (RLS), intrinsic fluorescence, Congo Red and far-UV CD) along with microscopy techniques i.e. atomic force microscopy (AFM) and transmission electron microscopy (TEM) to characterize the tartrazine-induced aggregation in myoglobin...

In medicine, patent blue violet (PBV) is utilized for staining lymphatic vessels in sentinel lymph node (SLN) surgery. Moreover, PBV (also called E131 ) is used as food additive. We report on a 51-year-old non-atopic female with early breast cancer, who was scheduled for SLN excision and experienced an intra-operative anaphylactic reaction. In diagnostics the skin prick test (SPT) was positive to PBV. Hypersensitivity reactions to PBV can arise after the first exposure in surgery as sensitization may arise from either PBV (E131) in foods (i...

Chromotrope FB (Chr FB) is a synthetic azo dye permitted for use in foods and medicines. An acceptable daily intake (ADI) of Chr FB was 0-0.5mg/kg in China. In this study, we synthesized a Chr FB hapten with an amino group to prepare its artificial immunogen. Polyclonal antibodies obtained from New Zealand rabbits were applied to develop an indirect competitive chemiluminescent immunoassay (icCLIA) to detect Chr FB in foods. A horseradish peroxidase (HRP)-luminol-H2O2 system was used to yield CL signal with p-iodophenol as an enhancement reagent...

In addition to its frequently-used antipyretic function, Gardenia jasminoides is also used in food or industrial dyeing. In ancient times, herbalists believed that the quality of Gardenia jasminoides for medical use was different from that for dye due to its different germplasm. Since the 1912, Gardenia jasminoides for dye was named "Shui(watery) Zhizi" in order to distinguish it from "Shan (hilly) Zhizi" . Henan was the earliest producing area for Gardenia jasminoides in ancient times, then after the Ming Dynasty, the producing area migrated to the Southern regions, including Jiangxi and Fujian Provinces...

Interaction of two food colorant dyes, amaranth and tartrazine, with lysozyme was studied employing multiple biophysical techniques. The dyes exhibited hypochromic changes in the presence of lysozyme. The intrinsic fluorescence of lysozyme was quenched by both dyes; amaranth was a more efficient quencher than tartrazine. The equilibrium constant of amaranth was higher than that of tartarzine. From FRET analysis, the binding distances for amaranth and tartrazine were calculated to be 4.51 and 3.93 nm, respectively...
