Valorization of apple peels through the study of the effects on the amyloid aggregation process of ?-casein

2021

Waste valorization represents one of the main social challenges when promoting a circular economy and environmental sustainability. Here, we evaluated the effect of the polyphenols extracted from apple peels, normally disposed of as waste, on the amyloid aggregation process of ?-casein from bovine milk, a well-used amyloidogenic model system. The effect of the apple peel extract on protein aggregation was examined using a thioflavin T fluorescence assay, Congo red binding assay, circular dichroism, light scattering, and atomic force microscopy. We found that the phenolic extract from the peel of apples of the cultivar "Fuji", cultivated in Sicily (Caltavuturo, Italy), inhibited ?-casein fib…

SYNTHESIS AND PHARMACOLOGICAL EVALUATION OF 7-SUBSTITUTED1-ETHYL-3,4,10-TRIMETHYL-1,10-DIHYDRO-11H-PYRAZOLO(3,4-c)(1,6)BENZODIAZOCIN-11-ONE: A NEW RI…

Derivatives of the title ring system of type 10 were obtained in good yield by fusion of the intermediates 12. Attempt to cyclize the acetylamino derivative 9 under Bischler-Napieralski conditions failed because of the insufficient electronic density in the position 4 of the pyrazole ring created by the adjacent carbonyl moiety. The derivatives of the new ring system, assayed as anxiolytic agents, showed no significant activity.

Antibacterial Activity of Desert Truffles from Saudi Arabia Against Staphylococcus aureus and Pseudomonas aeruginosa

2017

Abstract Medicinal mushrooms represent an unlimited source of polysaccharides with nutritional, antitumoral, antibacterial, and immune-stimulating properties. Traditional studies of epigeous higher Basidiomycetes have recently been joined by studies of hypogeous fungi and, in particular, of so-called desert truffles. With the aim to obtain novel agents against bacteria of clinical importance, we focused on the edible desert truffle mushrooms Tirmania pinoyi, Terfezia claveryi, and Picoa juniperi as sources of new antimicrobial agents. In particular, we investigated the in vitro antibacterial activity of acid-soluble protein extracts (aqueous extracts) of these 3 species against the Gram-pos…

Two end-members of carbonate slope evolution during the Late Cretaceous in the peri-Tethyan domain (Western Sicily and Southern Albania)

2019

Climatic and tectonic processes are major mechanisms influencing tropical carbonate platform development, sediment production and sediment export. Mass transport deposits (including slides, slumps and debrites) and calciturbidites are some of the sediment export products resulting from the interplay of aforementioned redeposition mechanisms. They reflect distinct variations in both production and export of sediments from the carbonate factories. The gravitary export deposits provide information on their sediment source and result in sedimentary sequences with specific porosity / permeability properties prone to host hydrocarbon resources. Climate-controlled sea-level variations are well-con…
