Changes in neuronal connectivity occurring upon the formation of aversive memory were examined in C57BL/6 (C57) mice 24 h after they were trained for tone fear conditioning (TFC) and contextual fear conditioning (CFC). Although TFC and CFC are amenable to distinct learning systems each involving a specific neural substrate, we found that mice trained in the two protocols showed the same increas...

This work aimed to evaluate the efficiency of different organic solvents such as, methanol, ethanol, dichloromethane, acetone, hexane and ethyl acetate for extraction of ( flavonoids and polyphenolic compounds(TFC and TPC respectively) from the orange peel. Also, the effect of these solvents on the yield percentage, chelating activity, antioxidant/radical scavenging capacity and reducing power ...

The potential bioactivity of dietary and medicinal endemic Helichrysum plants from Madeira Archipelago was explored, for the first time, in order to supply new information for the general consumer. In vitro antioxidant properties were investigated using DPPH, ABTS(•+), FRAP and β-Carotene assays, and the total phenolic content (TPC) and total flavonoid content (TFC) were also determined. Althou...

Grape pomace is a potential source of natural antioxidant and antimicrobial agents. Phenolic compounds, antioxidant, and antibacterial properties of pomace extracts from four Virginia-grown grape varieties were investigated. White grape pomaces had higher (P < 0.05) solvent extraction yield than red varieties. Concentrations of total phenolic (TPC), total flavonoid (TFC), total anthocyanin (TAC...

The aim of this study was to determine the antioxidant activity as well as total phenol (TPC) and total flavonoid content (TFC) in two fruits, apple (Malus domestica) and green beans (Phaseolus vulgaris). The antioxidant activities were examined by two different methods namely DPPH free radical scavenging activity and reducing power scavenging activity. The results showed that considerable amou...

The methanolic extracts of 13 accessions of purslane were analyzed for their total phenol content (TPC), total flavonoid contents (TFC), and total carotenoid contents (TCC) and antioxidant activity of extracts was screened using FRAP assay and DPPH radical scavenging methods. The TPC, TFC, and TCC ranged from 0.96 ± 0.04 to 9.12 ± 0.29 mg GAE/g DW, 0.13 ± 0.04 to 1.44 ± 0.08 mg RE/g DW, and 0.5...

OBJECTIVE To investigate mean platelet volume (MPV) levels in patients with coronary slow flow (CSF). METHODS 465 stable angina pectoris cases with angiographically normal coronary arteries were recruited [coronary slow flow group (n=76), control group (n=389)] in the observational retrospective cohort study. Clinical, biochemical and demographic variables including MPV were noted and coronar...

We report on results from an interdisciplinary research project of computer scientists, mechanical engineers and numerical analysts from industry and academia. We have designed and implemented a portable distributed memory parallel version of CFX-TfC, a state of the art computational fluid dynamics simulation software package that features finite volume discretization on unstructured hybrid gri...

Three commercial membranes (NF70, NF90 and TFC-SR) were firstly characterized in terms of pure water flux and the: rejection of uncharged (alcohols and sugars) compounds. Subsequently, the rejection of monovalent (sodium and chloride) and divalent (calcium and sulphate) ions in single (NaC1, CaC12 and Na2SO4) and binary (NaC1/Na2SO4, CaClJCaSO4, NaC1/CaC12 and Na2SO4/CaSO4) salt mixtures was st...

It has been proven that a versatile bio-glue, polydopamine, can firmly bind TiO2 (titanium dioxide) nanoparticles on thin film composite (TFC) membranes. In this work, the anti-fouling behaviour of this novel polydopamine-TiO2-modified membrane is evaluated, based on the static bovine serum albumin (BSA) surface adhesion of the membranes and the relative flux decline. The results show that the ...
