“The effects of jam processing on total phenolics, total flavonoids, total anthocyanins, and antioxidant capacities of fresh Rubus coreanus Miguel (bokbunja) fruits at various pH levels were investigated. Aqueous methanol of 80%(v/v) was found to be the most efficient solvent for extracting phenolics in fruits and jams. More than 90% of total phenolics, antioxidant capacities, and total flavonoids were retained after processing, while approximately 35% of total anthocyanins were lost. Among various pH treatments, jams prepared at pH 2.0-3.0 lost 33-35% of total anthocyanins, while treatments at pH 3.5-4.0 degraded 40-48% of total anthocyanins. Among the various treatments between pH 2.0 and 4.0, jam prepared at pH 3 had the highest sensory scores and overall acceptability. The results suggest that jam making with fruits rich in anthocyanins at lower pH may protect bioactive anthocyanins from thermal processing.”
“Background: Knockdown resistance in insects ALK assay resulting from mutation(s) in the voltage gated Na+ channel (VGSC) is one of the mechanisms
of resistance against DDT and pyrethroids. Recently a point mutation leading to Leu-to-Phe substitution in the VGSC at residue 1014, a most common kdr mutation in insects, was reported in Anopheles culicifacies-a major malaria vector in the Indian subcontinent. This study reports the TGF-beta inhibitor presence of two additional amino acid substitutions in the VGSC of an An. culicifacies population from Malkangiri district of Orissa, India.
Methods: Anopheles culicifacies sensu lato (s.l.) samples, collected from a population of Malkangiri district of Orissa (India), were sequenced
for part of the second transmembrane segment of VGSC and analyzed for the presence of non-synonymous mutations. A new primer introduced restriction analysis-PCR (PIRA-PCR) was developed for the detection of the new mutation L1014S. The An. culicifacies population was genotyped for the presence of L1014F substitution by an amplification refractory mutation system (ARMS) and for L1014S substitutions by using a new PIRA-PCR developed in this study. The results were validated through DNA sequencing.
Results: DNA sequencing of An. culicifacies individuals collected from district Malkangiri revealed the presence of three amino acid substitutions in the IIS6 transmembrane segments of VGSC, each one resulting from a single point mutation. Two alternative point mutations, 3042A>T transversion or 3041T>C transition, were found at residue L1014 leading to Leu (TTA)-to-Phe (TTT) or -Ser (TCA) changes, respectively. A third and novel substitution, Val (GTG)-to-Leu (TTG or CTG), was identified at residue V1010 resulting from either of the two transversions-3028G>T or 3028G>C.
