Antioxidant, brine shrimp lethality and analgesic properties of propolis from Bangladesh
In this study, we report for the first time the antioxidant, cytotoxic, and antinociceptive activities of propolis from Bangladesh (BDP). The antioxidant activities were measured by biochemical analyses while cytotoxicity was evaluated by brine shrimp lethality bioassay. Analgesic activity was evaluated by tail immersion and acetic acid ‐induced writhing models in mice. BDP contained higher concentrations of polyphenols, flavonoids, tannins, ascorbic acid, vitamin E, and reducing sugars, as compared to previous reports of propolis from several countries. BDP also exhibited higher free radical‐scavenging activities and ...

How do methanol and higher alcohols found in alcoholic beverages affect membrane fluidity and migration of granulocytes?
We examined the effects of OAAs alone and in combination with ethan ol on these processes. Granulocytes isolated from human blood were treated separately with methanol, ethanol, and a mixture of OAAs including methanol, 1‐propanol, 2‐propanol, 1‐butanol, 2‐butanol, isobutanol, and isoamyl alcohol at biologically relevant concentrations. The membrane fluidity and migration activity of granulocytes was examined by fluorescence anisotropy method and migration chambers, respectively. Our findings showed that OAAs increased membrane fluidity and migration activity of granulocytes in a concentration‐dependent manner an...

Purification and biochemical characterization of β‐d‐fructofuranosidase from Bacillus subtilis LYN12
AbstractThe purification and biochemical characterization of extracellular β‐d‐fructofuranosidase fromBacillus subtilis LYN12 was carried out. The enzyme was purified 6.94 folds over the crude extract by gel filtration chromatography with recovery of 15.58%. The molecular mass of ∼66 kDa estimated by SDS‐PAGE was confirmed by LC‐MS as 64512.31 Da. Bacterial β‐d‐fructofuranosidase was found to be a glycoprotein with 62.64% carbohydrate content, and exhibited enhanced activities at broad pH, temperature and stable at pH 7.0, 40°C, respectively. The enzyme showed high affinity ford‐sucrose. Kinetic parame...

Chemical compositions, functional properties, antioxidative activities, and glycaemic indices of raw and fermented tigernut tubers (Cyperus esculentus Lativum) flour
AbstractTigernut flour (TNF) samples were analyzed for chemical compositions, antioxidative activities, and glycaemic indices after processed as raw (RTN) and fermented (FTN‐24 FTN‐48& FTN‐72) flour by varying time. Fat, protein, and energy of TNF samples ranged as 40.41 –46.20 g/100 g, 8.83–10.06 g/100 g, and 570.02–599.84 kcal, respectively. Potassium and copper had the highest and lowest concentration, respectively. Essential fatty acids of TNF samples varied as 77.49%–80.01%, while essential amino acids plus histidine were 31.32–34.03 mg/100 g p rotein. Essential amino acid index and predicted bi...

Protective activity of caffeic acid and sinapic acid against UVB ‐induced photoaging in human fibroblasts
In this study, the protective effects of caffeic acid (CA) and sinapic acid (SA) on photoaging in human skin fibroblasts induced by UVB irradiation (30 mJ/cm2) were examined. The results revealed that exposure to UVB irradiation reduced cell viability by approximately 33% compared with the non ‐UVB irradiated control. However, CA and SA blocked the UVB irradiation‐induced cytotoxicity greater than the other phenolic acids. CA and SA also significantly inhibited the release of matrix metalloproteinase 1 (MMP‐1) and reduced the expression of MMP‐1 mRNA in UVB‐irradiated Hs68 cells . Furthermore, CA and SA reduced...

Biochemical changes of Coregonus peled myofibrillar proteins isolates as affected by HRGS oxidation system
In this study, the biochemical change of MP isolates as affected by HRGS oxidation system was proposed. Such chemical modification leads to loss of protein amino groups, shift in the isoelectric point of the protein, loss of solubility and functionality. Additionally, protein carbonyls have been found to be potentially toxic to humans, and relevant measurement of dityrosine as those have been found to cause health problems after oral administration. So such modifications are of technological and nutritional relevance. (Source: Journal of Food Biochemistry)

Anticancer activity and mechanism of action of fermented wheat germ extract against ovarian cancer
This study highlights that ethanol extract of FWG with yeast extract inhibits human ovarian cancer cell growth by inducing caspase‐3/7/9‐mediated apoptosis and downregulating ROS‐mediated NF‐κB activation and NK cell activation and that it can be considered a promising prophylactic food for fighting ovarian cancer.
