Ferritin is a shell-like carrier protein with an 8 nm diameter cavity which endows a natural space to encapsulate food and drug components. In this work, phytoferritin was unprecedentedly glycosylated by chitosan to fabricate ferritin-chitosan Maillard reaction products (FCMPs) (grafting degree of 26.17%, 24h, 55 degrees C). Results indicated that the amide I and II bands of ferritin were altered due to the chitosan grafting, whereas the ferritin spherical structure were retained. Simulated digestion analysis showed that the FCMPs were more resistant to pepsin and trypsin digestion as compared with ferritin alone. Furthermore, FCMPs were employed as carrier to encapsulate epigallocatechin gallate (EGCG) molecules with an encapsulation ratio of 12.87% (w/w), and the resulting FCMPs-EGCG complexes showed a slow release of EGCG in simulated gastrointestinal tract. Interestingly, different types of food components displayed different effects in EGCG release behavior from the FCMPs, wherein proanthocyanidin, milk and soy protein inhibited the EGCG release. In addition, the absorption of EGCG encapsulated in FCMPs in Caco-2 monolayer model was significantly improved as compared with free EGCG. This work provides a novel nano-vehicle for fabricating core-shell systems in food and drug delivery domain. (C) 2017 Elsevier B.V. All rights reserved.

A coated material with a nucleating surface for osseointegration is an attractive choice for dental implant materials. Layer-by-layer (LbL) self-assembly film coating was used to fabricate a nucleating surface for osseointegration to design coated dental implant materials. Silk fibroin (SF), collagen (Col), and poly (diallyldimethylammonium chloride) (PDDA) were selected as the base materials for the films. LbL self-assembly films of PDDA-SF-PDDA-Col were constructed with different n layers: n = 0 (control), 10, 20, 30, 40, and 50. Quartz crystal microbalance, atomic force microscopy, scanning electron microscopy, and wettability testing were used to analyze the multilayer formation, topography, morphology, and surface characteristics of the films, respectively. Molecular organization of the films was characterized by Fourier transform infrared and Raman spectroscopy. The biological performance was evaluated with osteoblast cell proliferation, alkaline phosphatase (ALP) activity, and total protein absorption. The multilayer showed a linear function of thickness and the number of layers. The multilayer films demonstrated mobility of amide I, II, III, and molecular skeletal vibration. The films had rough surfaces, hydrophilicity, biological performance to enhance cell proliferation, ALP activity, and total protein absorption. The results indicated the films were promising as a nucleating surface for osseointegration in the design of coated dental implant materials. (C) 2018 Elsevier Ltd. All rights reserved.

The extraction behaviour of Am(III) and other metal ions present in the fast reactor simulated high- level liquid waste (FR-SHLLW) was studied using a modifier-free solvent phase composed of N,N-di-octyl-2-hydroxyacetamide (DOHyA) in n-dodecane. Quantitative extraction of Am(III) was achieved with the co-extraction of all lanthanides, Y(III) and Mo(VI) in the first five stages of a 20-stage mixer-settler. During the stripping run with 0.5 M HNO3, Am(III), Ln(III) and Y(III) were quantitatively transferred to the aqueous product in three stages. The other extracted metal ions were retained in organic phase. The results showed that the extraction performance of DOHyA was superior to other amide extractant systems reported in the literature.

Treatment of the readily accessible spiro-cyclohexadienones from the PhI(OCOCF3)(2)-mediated spiro-cyclization of N-substituted benzanilides, with BF3 center dot Et2O initiates a tandem ring opening/closure reaction leading to the formation of the biologically interesting 8-hydroxy-phenanthridin-6(5H)-one compounds. This unique rearrangement pattern involves the ‘migration’ of the electron-deficient N-methyl carbamoyl moiety rather than the electron-rich aryl group as observed and reported previously in all other similar transformations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6893-26-1, in my other articles.

BackgroundPancreatic ductal adenocarcinoma (PDA) is a fatal disease with very poor prognosis. Development of sensitive and noninvasive methods to monitor tumor progression in PDA is a critical and unmet need. Magnetic resonance imaging (MRI) can noninvasively provide information regarding underlying pathophysiological processes such as necrosis, inflammatory changes and fibrotic tissue deposition.MethodsA genetically engineered KPC mouse model that recapitulates human PDA was used to characterize disease progression. MR measures of T-1 and T-2 relaxation times, magnetization transfer ratio (MTR), diffusion and chemical exchange saturation transfer were compared in two separate phases i.e. slow and rapid growth phase of tumor. Fibrotic tissue accumulation was assessed histologically using Masson’s trichrome staining. Pearson correlation coefficient (r) was computed to assess the relationship between the fibrotic tissue accumulation and different MR parameters.ResultsThere was a negative correlation between amide proton transfer signal intensity and tumor volume (r=-0.63, p=0.003) in the slow growth phase of the tumor development. In the terminal stage of rapid growth phase of the tumor development MTR was strongly correlated with tumor volume (r=0.62, p=0.008). Finally, MTR was significantly correlated with % fibrosis (r=0.87; p<0.01), followed by moderate correlation between tumor volume (r=0.42); T-1 (r=-0.61), T-2 (r=-0.61) and accumulation of fibrotic tissue.ConclusionsHere we demonstrated, using multi-parametric MRI (mp-MRI), that MRI parameters changed with tumor progression in a mouse model of PDA. Use of mp-MRI may have the potential to monitor the dynamic changes of tumor microenvironment with increase in tumor size in the transgenic KPC mouse model of pancreatic tumor.

The human chemokine interleukin-8 (IL-8; CXCL8) is a key mediator of innate immune and inflammatory responses. This small, soluble protein triggers a host of biological effects upon binding and activating CXCR1, a G protein-coupled receptor, located in the cell membrane of neutrophils. Here, we describe H-1-detected magic angle spinning solid-state NMR studies of monomeric IL-8 (1-66) bound to full-length and truncated constructs of CXCR1 in phospholipid bilayers under physiological conditions. Cross-polarization experiments demonstrate that most backbone amide sites of IL-8 (1-66) are immobilized and that their chemical shifts are perturbed upon binding to CXCR1, demonstrating that the dynamics and environments of chemokine residues are affected by interactions with the chemokine receptor. Comparisons of spectra of IL-8 (1-66) bound to full-length CXCR1 (1-350) and to N-terminal truncated construct NT-CXCR1 (39-350) identify specific chemokine residues involved in interactions with binding sites associated with N-terminal residues (binding site-l) and extracellular loop and helical residues (binding site-lI) of the receptor. Intermolecular paramagnetic relaxation enhancement broadening of IL-8 (1-66) signals results from interactions of the chemokine with CXCR1 (1-350) containing Mn2+ chelated to an unnatural amino acid assists in the characterization of the receptor-bound form of the chemokine.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 5977-14-0, Name is Acetoacetamide, molecular formula is C4H7NO2.

Prion transmission between species is governed in part by primary sequence similarity between the infectious prion aggregate, PrPSc, and the cellular prion protein of the host, PrPC. A puzzling feature of prion formation is that certain PrPC sequences, such as that of bank vole, can be converted by a remarkably broad array of different mammalian prions, whereas others, such as rabbit, show robust resistance to cross-species prion conversion. To examine the structural determinants that confer susceptibility or resistance to prion conversion, we systematically tested over 40 PrPC variants of susceptible and resistant PrPC sequences in a prion conversion assay. Five key residue positions markedly impacted prion conversion, four of which were in steric zipper segments where side chains from amino acids tightly interdigitate in a dry interface. Strikingly, all five residue substitutions modulating prion conversion involved the gain or loss of an asparagine or glutamine residue. For two of the four positions, Asn and Gln residues were not interchangeable, revealing a strict requirement for either an Asn or Gln residue. Bank voles have a high number of Asn and Gln residues and a high Asn:Gln ratio. These findings suggest that a high number of Asn and Gln residues at specific positions may stabilize -sheets and lower the energy barrier for cross-species prion transmission, potentially because of hydrogen bond networks from side chain amides forming extended Asn/Gln ladders. These data also suggest that multiple PrPC segments containing Asn/Gln residues may act in concert along a replicative interface to promote prion conversion.

Deep marine microorganisms survive under extreme ecological settings and harsh environmental conditions of low temperature, high salinity, and high atmospheric pressure making it significant of scientific interest. Southern Ocean (SO) is one such example of deep marine ecosystem and the microorganisms inhabiting in such hostile environment may produce different bioactive secondary metabolites. SO (Indian Sector) is relatively less documented in terms of microbial composition and community dynamics. The present study involves isolation of exopolysaccharides (EPSs) from three potent SO (Indian Sector) bacteria, optimization of the EPS production and partial characterization of them. Three different EPSs show varying structural conformation, that is from porous to strong flakes mimicking polymeric structure with C/N ratio ranging between 4 – 11. FTIR spectra have exhibited the presence of different active groups of carbohydrate moieties, water molecules and protein-associated amides. EPSs produced by marine microorganisms show high biotechnological promises such as drug carrier in pharmaceutical field, emulsifier and cryoprotectant in food-processing industry, detoxification of petrochemical oils and much more. The three bacterial isolates in this study showed potential of producing EPS biopolymer that can be further explored in terms of its proper biotechnological applications.
