1. Evaluation of residues of β-lactam, sulfonamide, tetracycline, quinolone, fluoroquinolone e pyrimidine in raw milk
Abstract Food quality and safety have been a concern of the world population, especially in relation to the chemical and microbiological hazards present in food. The presence of antimicrobial residues at levels above the maximum residue limit makes milk unsuitable for human consumption. In this context, the objective of this study was to analyze 184 raw milk

2. Response of root-knot nematode Meloidogyne javanica to ozone
RESUMO O nematoide das galhas, Meloidogyne javanica, é um dos principais agentes causadores de doenças de plantas em cultivos de verão em campos e estufas. A fim de reduzir as preocupações ambientais, os compostos com capacidade pesticida com resíduos insignificantes podem ser uma boa alternativa aos pesticidas químicos inseguros. Este estudo foi real

3. Milk quality parameters associated with the occurrence of veterinary drug residues in bulk tank milk
ABSTRACT Veterinary drug residues in bulk tank milk are important to all sectors of the dairy chain because they are one of the major factors which determine the safety of the final product. This study attempted to identify milk quality parameters that are associated with the occurrence of veterinary drug residues using multivariate principal component analy

4. Ocellatin peptides from the skin secretion of the South American frog Leptodactylus labyrinthicus (Leptodactylidae): characterization, antimicrobial activities and membrane interactions
Abstract Background The availability of antimicrobial peptides from several different natural sources has opened an avenue for the discovery of new biologically active molecules. To the best of our knowledge, only two peptides isolated from the frog Leptodactylus labyrinthicus, namely pentadactylin and ocellatin-F1, have shown antimicrobial activities. The

5. Sida tuberculata (Malvaceae): a study based on development of extractive system and in silico and in vitro properties
Sida tuberculata (Malvaceae) is a medicinal plant traditionally used in Brazil as an antimicrobial and anti-inflammatory agent. Here, we aimed to investigate the different extractive techniques on phytochemical parameters, as well as to evaluate the toxicity and antioxidant capacity of S. tuberculata extracts using in silico and in vitro models. Therefore, i

6. Evaluation of the antimicrobial activity of pecan nut [Carya illinoinensis (Wangenh) C. Koch] shell aqueous extract on minimally processed lettuce leaves
Abstract Pecan nutshell is a residue from food industry that has potential to be used as biopreservative in foods. The objective of this study was to evaluate the antimicrobial activity of pecan nutshell aqueous extract in vitro and its effectiveness to inhibit spoilage microorganisms on lettuce leaves. The results indicate that the aqueous extract presents

7. A titration model for evaluating calcium hydroxide removal techniques
Objective Calcium hydroxide (Ca(OH)2) has been used in endodontics as an intracanal medicament due to its antimicrobial effects and its ability to inactivate bacterial endotoxin. The inability to totally remove this intracanal medicament from the root canal system, however, may interfere with the setting of eugenol-based sealers or inhibit bonding of resin

8. Antifungal efficacy of Azadirachta indica (neem) - An in vitro study
AIM: To evaluate antimicrobial ability of neem leaf extract, 3% sodium hypochlorite (NaOCl) and 2% chlorhexidine (CHX) against Candida albicans. METHODS: Neem leaf extract was prepared by using absolute ethanol with fresh neem leaves, filtering the extract through muslin cloth, coarse residue and filter paper. Cultures of C. albicans were maintained on

9. Identification and antimicrobial resistance of microflora colonizing feral pig (Sus scrofa) of Brazilian Pantanal
Antimicrobial resistance of bacteria is a worldwide problem affecting wild life by living with resistant bacteria in the environment. This study presents a discussion of outside factors environment on microflora of feral pigs (Sus scrofa) from Brazilian Pantanal. Animals had samples collected from six different body sites coming from two separated geographic

10. Planejamento experimental na otimização da extração dos frutos de Syzygium cumini (L.) skeels
The aim of this study was to standardize the extractive solution of Syzygium cumini. The extractive solution was selected through a full factorial design, considering the extraction method (maceration-5-days, turbo extraction, percolation), extractor solvent (ethanol 50, 70, 96%) and plant material particle size 0.302 mm into a plant:solvent ratio (1:10), us

11. Peptídeos antimicrobianos: síntese, ensaios biológicos, estudos termodinâmicos e análise estrutural por RMN em meios biomiméticos
Many organisms employ noxious chemicals (e.g., amines, steroid derivatives, alkaloids and peptides) to defend themselves against predators and pathogenic microrganisms. Among these chemical agents stand out peptides that can be found in a wide variety of organisms including bacteria, fungi, plants, insects, fish, amphibians,arachnids and mammals. The vast ma

12. Funcionalidade dos extratos fenólicos obtidos pelo cultivo semi-sólido de resíduos de abacaxi (Ananas comusus L.) e goiaba (Psidium guajava L.)
Solid substrate cultivation (SSC) has become an efficient alternative towards rational use of agro industrial wastes and production of value-added products, mainly in developing countries. This work presents the production and functional application results of phenolic extracts obtained by solid substrate cultivation of pineapple (Ananas comosus L.) and guav
