13. Characterization and evaluation of sensory acceptability of ice creams incorporated with beta-carotene encapsulated in solid lipid microparticles
Abstract The feasibility of incorporating beta-carotene-loaded solid lipid microparticles (BCSLM) into vanilla ice creams was investigated, through the physico-chemical characterization and evaluation of sensory acceptability of the products products. The BCSLM were produced with palm stearin as the lipid phase, hydrolyzed soy protein isolate as the surfacta

14. Surfactant Protein A Expression in Chronic Rhinosinusitis and Atrophic Rhinitis
Introduction Surfactant protein A (SP-A) exhibits antimicrobial properties and interacts with a variety of respiratory tract pathogens.
Objective The objective of this study was to detect the presence of SP-A and measure its alterations in chronic rhinosinusitis (CRS) and primary atrophic rhinitis (PAR)

15. NANOPARTÍCULAS DE PROTEÍNA ISOLADA DE SOJA EM ÁGUA: EFEITO DA FORÇA IÔNICA E DAS CONCENTRAÇÕES DE PROTEÍNA E SURFACTANTE
Soft nanoparticles of size 200-400 nm were obtained from soybean protein isolate (SPI). The particles were formed and suspended in water by the coacervation of aqueous suspensions of SPI in hostile buffered aqueous solutions in the presence of surfactants. We investigate the effect of storage, ionic strength, and concentrations of SPI and surfactant on nanop

16. Influence of salts on the coexistence curve and protein partitioning in nonionic aqueous two-phase micellar systems
Aqueous two-phase micellar systems (ATPMS) can be exploited in separation science for the extraction/purification of desired biomolecules. Prior to phase separation the surfactant solution reaches a cloud point temperature, which is influenced by the presence of electrolytes. In this work, we provide an investigation on the cloud point behavior of the nonion

17. Surfactant protein A is decreased in the lung of rats with hepatopulmonary syndrome
PURPOSE:To evaluate surfactant protein A levels in an hepatopulmonary syndrome rat model. To date, there have been no studies aimed at evaluating surfactant levels in the setting of cirrhosis or hepatopulmonary syndrome.METHODS:A total of 35 rats were divided into control, sham, and experimental HPS groups. We evaluated surfactant protein A levels in rats an

18. Effect of the addition of soy lecithin and Yucca schidigera extract on the properties of gelatin and glycerol based biodegradable films
Gelatin-based films containing soy lecithin or Yucca schidigera extract and glycerol as plasticizer were produced by casting and characterized for their mechanical properties, water vapor permeability (WVP), water solubility, opacity and morphology. The addition of glycerol reduced the tensile strength, with a difference of ~ 68% between the values for the m

19. Síntese e caracterização de copolímeros do tipo ABA para encapsulação de hemoglobina bovina
The use of biopolymers for the development of oxygen carriers has been extensively investigated. In this work, three different ABA triblock copolymers were synthesized and used to encapsulate purified bovine hemoglobin, using a double emulsion technique. The effect of polymer composition, homogenization velocity, and addition of a surfactant, on the protein

20. Envolvimento das pequenas vias aéreas na Síndrome do Desconforto Respiratório Agudo: papel da inflamação, das alterações do surfactante e da apoptose de células epiteliais / Expression of acute phase cytokines, surfactant proteins, and epithelial apoptosis in small airways of human ARDS
Alguns estudos sugerem que as pequenas vias aéreas têm um papel importante na fisiopatologia da lesão pulmonar aguda/ síndrome do desconforto respiratório agudo (LPA/SDRA). O epitélio respiratório que reveste as vias aéreas é capaz de liberar mediadores inflamatórios e está relacionado ainda com a produção de surfactante nas vias aéreas. Até o

21. PRODUÇÃO DE ANTÍGENOS DO VÍRUS DA ARTRITE ENCEFALITE CAPRINA PARA IMUNODIAGNÓSTICO / PRODUCTION OF VIRUS ANTIGENS OF GOATS FOR ARTHRITIS ENCEPHALITIS IMMUNODIAGNOSTIC
The small ruminantslentiviruses are responsible for a significant economic loss that enabled the development of efficient control and monitoring programs in Europe and other countries.The diagnosis of CAE is mainly based on serological tests.The World Organisation for Animal Health (OIE) recommends the use of agarose gel immunodiffusion (AGID) for its low co

22. Surfactant protein B gene polymorphism in preterm babies with respiratory distress syndrome
The etiology of respiratory distress syndrome (RDS) is multifactorial and multigenic. Studies have suggested that polymorphisms and mutations in the surfactant protein B (SP-B) gene are associated with the pathogenesis of RDS. The objectives of this study were to determine and compare the frequencies of SP-B gene polymorphisms in preterm babies with and with

23. Surfactant protein B gene polymorphisms analysis: comparison between preterm newborns with and without respiratory distress syndrome / Análise de polimorfismos do gene que codifica a proteína B do surfactante: comparação entre recém-nascidos pré-termo com e sem síndrome do desconforto respiratório
A síndrome do desconforto respiratório (SDR) é causada pela deficiência transitória de surfactante pulmonar em recém-nascidos (RN) prematuros nos primeiros dias de vida. Estudos sugerem que a etiologia da SDR seja multifatorial e multigênica. A proteína B do surfactante (SP-B) é fundamental para o metabolismo do surfactante e para uma função pulmo

24. Efeitos da atrazina e do duodecil sulfato de sódio sobre a estabilidade de eritrócitos humanos
CHAPTER II: This work evaluated the in vitro influence of albumin on the stability of human erythrocytes against the herbicide atrazine present in a commercially available preparation. The sigmoidally shaped curves, observed for the dependence between absorbance at 540 nm and the atrazine concentration in 9 g/L NaCl solution, were characterized by the midpoi
