Prussian blue nanocubes with peroxidase-like activity for polyphenol detection in commercial beverages.

The present study describes an efficient method for the determination of polyphenol content in beverages based on a composite material of graphene oxide decorated with Prussian blue nanocubes (rGO/PBNCs). In this method, rGO/PBNCs act as a nanoenzyme with peroxidase-like catalytic activity and produce a colorimetric product in the presence of hydrogen peroxide and tetramethylbenzidine (TMB). To verify the effectiveness of the method, we used two model standards for antioxidants: gallic acid (GA) and tannic acid (TA).

Natural Polymers as Carriers for Encapsulation of Volatile Oils: Applications and Perspectives in Food Products.

The technique of encapsulating different materials into matrices that can both protect and release their contents under specific circumstances is known as encapsulation. It serves the primary function of shielding delicate components from outside influences, including heat, light, and humidity. This can be accomplished by a variety of procedures that, depending on the method and materials selected, result in the creation of particles with various structures.

Sensory, textural, physico-chemical and enzymatic characterization of melted cheese with added potato and carrot peels.

Food waste is one of the biggest societal problems in the globe due to its detrimental consequences on the environment. According to estimates from the Food and Agriculture Organization, this comes to about 1.3 billion tonnes per year.

Use of Yoghurt Enhanced with Volatile Plant Oils Encapsulated in Sodium Alginate to Increase the Human Body's Immunity in the Present Fight Against Stress.

(1) Background: The COVID-19 pandemic and the imposition of strict but necessary measures to prevent the spread of the new coronavirus have been, and still are, major stress factors for adults, children, and adolescents. Stress harms human health as it creates free radicals in the human body. According to various recent studies, volatile oils from various aromatic plants have a high content of antioxidants and antimicrobial compounds.

[Madura's foot (mycetoma)].

Mycetoma is a chronic disorder involving the skin, bones and soft tissues and is characterized by multiple discharge sinuses, nodules and swelling of the affected part. It may be caused by actinomycetes or eumycetes. It most commonly involves the foot but occasionally involve the hands, back or shoulders.

Rain and throughfall chemistry in a Norway spruce forest in the Western Prealps.

From January 1987 to December 1989 precipitation was collected in an open field in a forested area of the Western Prealps. The site faces the intensely industrialized area of the Po Valley. In a Norway spruce plantation, next to the open field sampler, throughfall was collected from January 1987 to August 1989 for a period of 32 months.

[Hemodynamic status in liver cirrhosis with portal hypertension: a retrospective study on 49 patients].

The Authors report on the data obtained and their evaluation by means of analysis of seven variables and four indices, in 49 cirrhotic patients with portal hypertension and in 10 control patients. Haemodynamic analysis offers the possibility of identifying the dynamic transition stages of a response to stress showing varying degrees of compensation and establishing categories of patients on the basis of cardiovascular and metabolic parameters in relation to liver damage. The Authors, according to Siegel studies, retain that this is a valid method which enables us to obtain useful information on the haemodynamic status of the cirrhotic patient with portal hypertension.
