Two cosegregating single-nucleotide polymorphisms (SNPs) in human TLR4, an A896G transition at SNP rs4986790 (D299G) and a C1196T transition at SNP rs4986791 (T399I), have been associated with LPS hyporesponsiveness and differential susceptibility to many infectious or inflammatory diseases. However, many studies failed to confirm these associations, and transfection experiments resulted in conflicting conclusions about the impact of these SNPs on TLR4 signaling. Using advanced protein modeling from crystallographic data of human and murine TLR4, we identified homologous substitutions of these SNPs in murine Tlr4, engineered a knock-in strain expressing the D298G and N397I TLR4 SNPs homozygously, and characterized in vivo …

Production And Properties Of Resistant Maltodextrin From Cassava Starch, Kamonrat Trithavisup
Chulalongkorn University Theses and Dissertations (Chula ETD)
This research aimed to determine the effects of processing conditions on molecular structure and selected properties of cassava-derived resistant dextrins (RDs) and resistant maltodextrins (RMDs). Cassava starch was mixed with hydrochloric acid solution to obtain the final acid concentration of 0.04-0.10% dry starch basis, dried at 50oC until having <5% moisture, and dextrinized at 100-120oC for 60-180 min. As acid concentration, heating temperature and time increased, water solubility, reducing sugar content, total dietary fiber (TDF) content and proportion of high molecular weight fiber fraction of RDs increased while their whiteness decreased. For the solution containing RDs produced under mild conditions (0.04-0.08% HCl, 100°C, 60 min), an endothermic peak at 45-70oC, having enthalpy of 1.66-2.14 J/g was detected. However, no endotherm was detected from the solution of RDs processed under extreme conditions. Harsher dextrinization conditions resulted in the RDs with slightly higher molecular weight but containing shorter branched chains. Dextrinization resulted in the formation of α-1,2, α-1,6, β-1,2, β-1,4 and β-1,6 in RDs. Lower proportion of α-1,4 linkage and α-/β-reducing ends with higher proportion of β-1,2, β-1,4, α-/β-1,6 linkages and degree of branching (DB) were found in RDs prepared under stronger dextrinization conditions. Although indigestible portion was enhanced by dextrinization, TDF of the RDs were only 7-47%. To increase the TDF content, RDs prepared from 5 different conditions (0.04% and 0.06% HCl, 120oC, 60-180 min), having >30% TDF, were selected for RMD production. The 30% RD solutions were treated with commercial α-amylase enzyme at 70oC, pH 6, for 90 and 120 min, to obtain the final dextrose equivalent of 8 and 12, respectively. The samples were then purified and spray dried. Alpha-amylase treatment produced RMD with shorter …
