6-Gingerol [5-hydroxy-1-(4-hydroxy-3-methoxyphenyl) decan-3-one], the bio-active ingredient of the popular Indian spice ginger (Zingiber officinale Roscoe), is well-known for its pharmacological and physiological actions. The potent antioxidant, antiemetic, antiulcer, antimicrobial, analgesic, h...

The root of the ginger plant (Zingiber officinale) is rich in bioactive phytochemicals, including phenolic gingerols and gingerol-derived shogaols responsible for many of the reported medicinal properties of ginger root extract. Gingerol homologs are differentiated based on the length of their u...

Gingerol - [6]-gingerol ((S)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-3-decanone; [6]-G) - is a phenolic compound with several pharmacological properties. Herein, the aim of the study was to evaluate the toxicogenic effects of [6]-G on Artemia salina nauplii, Allium cepa, HL-60 cell line and Sarc...

Biofouling is a major problem in operating reverse osmosis (RO) processes. Although biocides such as chlorine are commonly used to reduce biofouling, their strong oxidative activity and toxicity negatively affect the operation of RO processes. 6-gingerol analogs, structural derivatives of the ma...

A study has been made of the in vitro effect of 11 antibiotics on Trichomonas vaginalis.The results indicate that endomycin demonstrates superior trichomonacidal activity to the other antibiotics tested.The action of endomycin on T. vaginalis is lytic.

The mode of action for endomycin-neomycin synergism against Candida albicans was postulated to be an action of endomycin which influences permeability of the cell membrane and facilitates the entry of neomycin in the cell. A neomycin-resistant strain was also found to be resistant to endomycin, ...

β-conglutin has been identified as a major allergen for Lupinus angustifolius seeds. The aim of this study was to evaluate the binding of IgE to five recombinant β-conglutin isoforms (rβ) that we overexpressed and purified and to their natural counterparts in different lupin species and culti...

The present study aimed to analyze the mechanism of action of a hydrolyzed gamma-conglutin fraction (Cgh) extracted from Andean L. mutabilis legume on glucose metabolism. At 5 mg/mL, Cgh from L. mutabilis inhibited dipeptidyl peptidase IV activity (DPP-IV) (100%), and increased (p

Lupine has been increasingly used in food applications due to its high nutritional value and excellent functional properties. However, there has been a response to the increasing number of severe cases of lupine allergies reported during the last decade, and as a result lupine was recently added...

Surface plasmon resonance imaging (SPRi) is a label-free detection method that offers a suitable and reliable platform for the real time monitoring of biomolecular interactions. In the work reported here, SPRi was used to evaluate the affinity and specificity of three different aptamers selected...

The development of functional food ingredients using legume seed proteins has potential for nutraceutical use. We purified recombinant β-conglutin proteins (rβ1 to rβ4, and rβ6) from narrow-leafed lupin using affinity–chromatography, and evaluated their anti-inflammatory activity using ex v...

Recently, lupin seed (Lupinus albus L., Fabaceae) products have emerged as a functional food due to their nutritional and health benefits. Numerous reports have demonstrated the hypoglycemic effects of lupin's gamma conglutin protein; nonetheless, its mechanism of action remains elusive. To...

Interaction with model phospholipid membranes of lupin seed γ-conglutin, a glycaemia-lowering protein from Lupinus albus seeds, has been studied by means of Fourier-Transform infrared spectroscopy at p2H 7.0 and at p2H 4.5. The protein maintains the same secondary structure both at p2H 7.0 and ...

A simple, selective and accurate reverse phase HPLC method was developed for detection and quantitation of γ-conglutin from lupin seed extract. A linear gradient of water and acetonitrile containing trifluoroacetic acid (TFA) on a reverse phase column (Agilent Zorbax 300SB C-18), with a flow ra...

A simple, rapid and economic lateral flow immunochromatographic assay (LFICA) was designed for ultrasensitive detection of β-conglutin. Instead of antibodies and gold nanoparticles (AuNPs) used in conventional LFICA, a cognate aptamer duo, binding to β-conglutin and Fe3O4@Au core-shell nanopar...

BackgroundLupin, the largest legume crop in Australia, is gaining global attention because of its unique protein γ-conglutin, which has shown promise as a nutraceutical for controlling blood glucose level and thus reducing the risk of type II diabetes development. Type II diabetes is a chronic ...

Here we have used five non-fluorinated cosolvents (acetonitrile, ethanol, methanol, sec-butanol and ter-butanol) at increasing concentrations and analyzed their aggregation inducing behavior on interaction with conalbumin (CA). The aggregates were identified as amorphous by performing spectrosco...

Bee products have been used since ancient times to treat many diseases, including respiratory ailments. The present study aimed to examine the modulatory effect of honey, royal jelly, and propolis extract on peripheral blood leukocytes and lung inflammation in a mouse conalbumin-induced asthma m...

The objective of this study was to determine the thermodynamic parameters (ΔtrG, ΔtrH and ΔtrS) associated with lysozyme and conalbumin partitioning in aqueous two-phases systems (ATPS). Influence of salt type and polyethylene glycol (PEG) concentrations on the partition coefficient of lysozy...

In this study we are reporting the conformational modulation as well as the plausible mechanism of structural perturbation in conalbumin (CA). The overall structure of CA is altered by the change in dielectric constant upon addition of fluoroalcohols (TFE and HFIP). We studied the formation of a...
