1. Bovine colostrum: benefits of its use in human food
Abstract Colostrum is the first secretion of the mammary gland produced after birth, differentiating itself from mature milk because it has a higher concentration of proteins, immunoglobulins, vitamins, minerals, bactericides (lactoferrin, lysozyme and lactoperoxidase) and growth factors. The use of bovine colostrum for human consumption has been registered

2. Histatin 5 and human lactoferrin inhibit biofilm formation of a fluconazole resistant Candida albicans clinical isolate
Abstract:Candida albicans is the most important fungal pathogen that causes infections in humans. Biofilms are hard-to-treat structures due to their high antifungal resistance. Saliva is a fluid that contains antimicrobial substances acting as the first-line of defense against pathogens, and its immune components may be potential tools for the discovery of n

3. Stability and rheological behavior of coconut oil-in-water emulsions formed by biopolymers
Abstract Proteins are frequently used as emulsifiers and stabilizers. In this work, two proteins with different isoelectric points were used: lactoferrin and ovalbumin. Solutions containing different proteins ratios, with different pH values, were stored for 7 days at 25 °C to analyze the system stability. Systems containing 3% w/v lactoferrin remained sta

4. Lactoferrin, chitosan and Melaleuca alternifolia-natural products that show promise in candidiasis treatment
Abstract The evolution of microorganisms resistant to many medicines has become a major challenge for the scientific community around the world. Motivated by the gravity of such a situation, the World Health Organization released a report in 2014 with the aim of providing updated information on this critical scenario. Among the most worrying microorganisms,

5. STERIC MASS ACTION MODEL FOR LACTOFERRIN ADSORPTION IN CRYOGEL WITH IMMOBILIZED COPPER IONS
Abstract Parameters of equilibrium adsorption obtained from experiments using immobilized metal affinity chromatography (IMAC) were used to evaluate the applicability of the steric mass-action (SMA) model to describe the adsorption of lactoferrin to cryogel resin under different conditions. The adsorption of lactoferrin on continuous supermacroporous cryogel

6. PARTIÇÃO DE PROTEÍNAS DE SORO DE LEITE EM SISTEMAS AQUOSOS BIFÁSICOS BASEADOS EM LÍQUIDOS IÔNICOS
In this work, we used an aqueous two-phase system (ATPS) consisting of the ionic liquid [C4mim][Cl] and the salt K2HPO4 to partition α-lactalbumin, β-lactoglobulin, and lactoferrin whey proteins. Extraction efficiency values above 87% indicate that the proteins primarily migrated to the ionic liquid-rich phase (top phase). Partition coefficient values rang

7. Lactotransferrin gene functional polymorphisms do not influence susceptibility to human immunodeficiency virus-1 mother-to-child transmission in different ethnic groups
Lactotransferrin, also known as lactoferrin, is an iron binding glycoprotein that displays antiviral activity against many different infectious agents, including human immunodeficiency virus (HIV)-1. Lactotransferrin is present in the breast milk and in the female genitourinary mucosa and it has been hypothesised as a possible candidate to prevent mother-to-

8. Antimicrobial Activity and Synergism of Lactoferrin and Lysozyme Against Cariogenic Microorganisms
O presente estudo avaliou, in vitro, o efeito antimicrobiano das proteínas salivares lactoferrina e lisozima sobre micro-organismos envolvidos no processo carioso, obtendo suas concentrações inibitórias mínimas (CIM) e bactericidas mínimas (CBM). Cepas de Streptococcus mutans (ATCC 25175) e Lactobacillus casei (ATCC 7469) foram submetidas a macrodilui�

9. ASSESSMENT OF THE RESPONSE OF PATIENTS WITH CROHN'S DISEASE TO BIOLOGICAL THERAPY USING NEW NON-INVASIVE MARKERS: lactoferrin and calprotectin
Contexto O uso de marcadores fecais para a monitorização da doença de Crohn é muito importante para a avaliação da resposta ao tratamento instituído. Objetivo Avaliar a atividade inflamatória da doença de Crohn comparando os marcadores fecais (calprotectina e lactoferrina), colonoscopia com biópsias, Crohn's Disease Activity Index (CDAI) e marca

10. Biofilm biomass disruption by natural substances with potential for endodontic use
This study evaluated the in vitro effects of four natural substances on the biomass of bacterial biofilms to assess their potential use as root canal irrigants. The following substances and their combinations were tested: 0.2% farnesol; 5% xylitol; 20% xylitol; 0.2% farnesol and 5% xylitol; 0.2% farnesol, 5% xylitol, and 0.1% lactoferrin; 5% xylitol and 0.1%

11. Influência das proteínas salivares e plasmáticas no desenvolvimento de biofilmes de Candida albicans / The influence of salivary and plasmatic proteins on the development of Candida albicans biofilms
The development of Candida albicans biofilms may be mediated by a differential expression of proteic ligand sites in the acquired pellicle formed onto the oral prosthesis surfaces. Therefore, the main objective of this study was to evaluate the influence of salivary and plasmatic-derived proteins on the development of C. albicans biofilms. In the first chapt

12. Differential expression of salivary glycoproteins in aggressive and chronic periodontitis
OBJECTIVES:The aim of this study was to compare the pattern of secretion and the expression of mucin glycoprotein-2 (MG2) and lactoferrin in individuals with or without periodontitis. MATERIAL AND METHODS: Five individuals with aggressive periodontitis (APG), 5 with generalized chronic periodontitis (CPG) and 5 without periodontitis (CG) were enrolled after
