Spectrofluorimetric analyzes of thiamine and riboflavin in monofloral honey varieties of africanized bees (Apis mellifera).

This research aimed to study the validation of a viable and low-cost spectrofluorimetric method, capable of detecting and quantifying B vitamins in floral varieties of bee honey. The analyzes were performed using chemical and operational methods of pre-defined solutions and standards, performed in triplicate and the results expressed as mean ± standard deviation. The data were recorded in a Microsoft Office Excel spreadsheet (version 2013) and studied using the statistical program Bioestatic version 3.

Equilibrium, kinetics and thermodynamics of lead (II) adsorption in bioadsorvent composed by Caryocar coriaceum Wittm barks.

The improper disposal of waste containing toxic metals promotes serious environmental problems. Biosorption stands out as a powerful technique in removing toxic metals from aqueous solutions, making it an efficient and low-cost technique, since it makes use of abundant materials and of natural origins. This work aimed to study the application of the bark of Caryocar coriaceum Wittm, as a possible bioabsorbent for the removal of Lead (II) present in aqueous solutions, for this, residues of this material were collected in a public market, where they were washed and dried, then crushed, sieved (32mesh) and washed again, to then be used in the kinetic, isotherm and thermodynamic tests of lead (II) ions adsorption.

Modulation of antibiotic resistance by the essential oil of Ocimum gratissimum L. in association with light-emitting diodes (LED) lights.

This study aimed to evaluate the antibacterial and antibiotic-enhancing effects of the essential oil obtained from Ocimum gratissimum L. (OEOg) alone or in association with light-emitting diodes (LED) lights. The essential oil was obtained by hydrodistillation and its chemical composition analysed by gas chromatography coupled to mass spectrometry.

A socio-environmental perspective on pesticide use and food production.

Pesticides are part of a large group of organic compounds with different physicochemical characteristics, designed to control and prevent pests in various crops and plantations, improving productivity. This works provides a perspective on pesticide use in current agriculture with the aim of identifying the influence of pesticides on food production and their impact on the environment. Therefore, it is necessary to highlight the importance of determining pesticide residues in food, aiming to ensure food safety, since these compounds can represent risks to human health and the environment.

Evaluating the presence of pesticides in bananas: An integrative review.

Introduction: Pesticides are organic compounds widely used in modern agriculture, being relevant for helping plantations and increasing food production. The banana, a fruit with oriental origin, stands out for being widely produced in tropical and subtropical regions which, like other matrices, is susceptible to pest action. This review aims to evaluate the presence of pesticides in bananas according to Brazilian, European and Codex legislation.

Effect of seasonality on chemical profile and antifungal activity of essential oil isolated from leaves (Kunth) O. Berg.

Medicinal plants play a crucial role in the search for components that are capable of neutralizing the multiple mechanisms of fungal resistance. (Kunth) O. Berg is a plant native to Brazil used as both food and traditional medicine to treat diseases and symptoms such as stomach ache and diarrhea, whose symptoms could be related to fungal infections from the genus .

Molecular mechanism underlying orofacial antinociceptive activity of Vanillosmopsis arborea Baker (Asteraceae) essential oil complexed with β-cyclodextrin.

Background: Vanillosmopsis arborea Baker has recognized economic value owing to the high content of (-)-α-bisabolol (BISA) in the essential oil of its stem (EOVA). The antinociceptive effect of EVOA has already been demonstrated, and β-cyclodextrin (βCD) is known to improve the analgesic effect of various substances.

Purpose: Thus, we aimed to evaluate the orofacial antinociceptive effect of a complex containing EOVA-βCD in rodents.
