Dyes and pigments used in foods: an integrative literature review
Oliveira, Micael Estevão Pereira de; Silva , Wildson Max Barbosa da; Alves, Daniela Ribeiro; Andrade Neto, João Batista de; Morais, Selene Maia deThe food colors are, in many countries, widely used to give food increased visual sensory quality, aiming, thus, the growth of the consumer market. Aware of this, the present work aimed to reevaluate the general properties of synthetic food dyes and natural pigments, the latter being generally used to replace the former. Then, the current analysis was based on the search for the strategy, selection of articles ...
Comparison of fat percentage, fat mass and slim mass between veteran practicant...
Andrade Neto, João Batista de; Navarro, Antonio Coppi; Pereira, Gabriel Moreira; Ferreira, Rayssa Marques; Navarro, Francisco; Salgado Filho, NatalinoAim: The aim was to compare the percentage of fat, fat mass and lean mass between veteran and novice Krav-Maga practitioners during 16-week Krav-Maga training. Materials and Methods: Thirty Krav-Maga practitioners participated voluntarily, being: veterans (n = 15), who practiced Krav-maga for at least 3 years and beginners (n = 15) who are starting this Krav-Maga practice. The physical training program was deve...
Antifungal activity of palmatine against strains of Candida spp. resistant to a...
Campos, Rosana de Sousa; Silva, Cecília Rocha da; Andrade Neto, João Batista de; Sampaio, Letícia Serpa; Nascimento, Francisca Bruna Stefany Aires doThe incidence of fungal infections has increased and it is necessary to seek new antifungals that also act against resistant strains. Palmatine is a protoberberine alkaloid noteworthy for its various pharmacological properties, including antifungal properties. The objective of this study was to evaluate the activity of palmatine against Candida spp. strains resistant to azole in planktonic cells and biofilm, an...
In vitro evaluation of the curcumin against fluconazole-resistant strains of Ca...
Freitas, Daniel Domingues; Silva, Cecília Rocha da; Andrade Neto, João Batista de; Campos, Rosana de Sousa; Sampaio, Letícia SerpaThe isolates of Candida spp. and Cryptococcus neoformans were inhibited by curcumin, with different degrees of inhibition among species, with MICs ranging from 8-64 μg/mL. After exposure of the C. albicans strains to curcumin, it was observed a decrease in the number of viable cells and damage to cell membranes, the mitochondrial function of C. albicans cells appears to be affected after exposure to curcumin. O...
Ibuprofen antifungal activity on both planktonic and biofilm forms of fluconazo...
Sampaio, Letícia S.; Silva, Cecília R. da; Campos, Rosana S.; Nascimento, Francisca Bruna Stefany Aires do; Andrade Neto, João Batista deOver the past few decades, researches have reported an increased incidence of invasive candidiasis and suggested that the majority of infections produced by this pathogen are associated with biofilm growth, which are more resistant to antimicrobial agents than planktonic cells. In addition to these problems, there are few antifungal agents available and it is necessary the development of novel therapeutic strat...
Avaliação in vitro do sinergismo da cetamina com derivados azólicos em micro-or...
Andrade Neto, João Batista deThe emergence of Candida spp. with resistance to antifungal compounds, mainly the azoles class, is a growing problem in hospitals around the world and are associated with a high morbidity and mortality, in addition to being related to a high economic burden at the hospital level. In this way combined drug therapy has become one of the most widely used and effective strategies to alleviate this problem. In the p...

Andrade Neto, João Batista de; Silva, Cecília R. da; Nascimento, Francisca Bruna Stefany Aires do; Sampaio, Letícia Serpa; Silva, Anderson R. daAntimicrobials benefited the history of medicine by revolutionizing the treatment of infectious diseases. However, its consequent and continuous use has led to the emergence of microorganisms which once were considered safe, but have become feared as potentially lethal pathogens (Bowler et al., 2012). Staphylococcus aureus infections are highlighted for being a major cause of systemic infections, and for being ...
Effects of piperonal nitro derivatives on candida species : antifungal activity...
Andrade Neto, João Batista de; Silva, Cecília Rocha da; Campos, Rosana de Sousa; Nascimento, Francisca Bruna Stefany Aires do; Freitas, Daniel DominguesRecently, there has been a significant increase in invasive fungal infections, the treatment of which is limited to a quite small number of antifungal drugs. Natural products represent an important source of antifungal agents, mainly because of their natural coexistence with fungi present in each biome. Derivatives or semi-synthetic products can be used to optimize the pharmacological profile of natural product...

Ribeiro, Paulo Riceli Vasconcelos; Araújo, Ana Jérsia; Costa-Lotufo, Letícia Veras; Braz-Filho, Raimundo; Nobre Júnior, Hélio VitorianoTwo new steroidal saponins, (25R)-spirost-5-ene-3β,26β-diol 3-O-α-l-rhamnopyranosyl-(1 → 4)-α-l-rhamnopyranosyl-(1 → 4)-[(1 → 2)-α-l-rhamnopyranosyl]-β-d-glucopyranoside (1) and (25R)-spirost-6-ene-3β,5β-diol 3-O-α-l-rhamnopyranosyl-(1 → 4)-α-l-rhamnopyranosyl-(1 → 4)-[(1 → 2)-α-l-rhamnopyranosyl]-β-d-glucopyranoside (2), along with the known diosgenin 3-O-α-l-rhamnopyranosyl-(1 → 4)-α-l-rhamnopyranosyl-(1 → 4)...
Berberine antifungal activity in fluconazole-resistant pathogenic yeasts : acti...
Silva, Anderson Ramos da; Andrade Neto, João Batista de; Silva, Cecília Rocha da; Campos, Rosana de Sousa; Silva, Rose Anny CostaThe incidence of fungal infections and, in particular, the incidence of fungal antibiotic resistance, which is associated with bio- film formation, have significantly increased, contributing to morbidity and mortality. Thus, new therapeutic strategies need to be developed. In this context, natural products have emerged as a major source of possible antifungal agents. Berberine is a pro- toberberine-type isoquin...
