13. Solubility and Bioaccessibility of Ba, Ca, Cr, Cu, Fe, Mg, Mn, P, Sr and Zn in Slim Coffee Infusions by in vitro Gastrointestinal Digestion
Solubility and bioaccessibility of Ba, Ca, Cr, Cu, Fe, Mg, Mn, P, Sr and Zn in slim coffees were investigated using an in vitro method. Two different compositions of solutions simulating gastric and intestinal juices were tested: SGJ1 + SIJ1 (0.02% pepsin in 0.10 mol L-1 HCl; 0.015% pancreatin with 0.15% bile salts in 0.10 mol L-1 NaHCO3) and SGJ2 + SIJ2 (0.

14. ACE-I inhibitory properties of hydrolysates from germinated and ungerminated Phaseolus lunatus proteins
Phaseolus lunatus protein concentrates and the proteases Alcalase(R) and Pepsin-Pancreatin were used for the production of protein hydrolysates that inhibit angiotensin-I converting enzyme (ACE). Protein concentrate obtained from germinated and ungerminated seeds flour was hydrolyzed with Alcalase(R) at enzyme/substrate ratio (E/S) 1/10 and during 0.5 and 2.

15. Isolation of a thermostable acid phytase from Aspergillus niger UFV-1 with strong proteolysis resistance
An Aspergillus niger UFV-1 phytase was characterized and made available for industrial application. The enzyme was purified via ultrafiltration followed by acid precipitation, ion exchange and gel filtration chromatography. This protein exhibited a molecular mass of 161 kDa in gel filtration and 81 kDa in sodium dodecyl sulfate polyacrylamide gel electrophor

16. Effects of sequential enzymatic hydrolysis on structural, bioactive and functional properties of Phaseolus lunatus protein isolate
Significant initiatives exist within the global food market to search for new, alternative protein sources with better technological, functional, and nutritional properties. Lima bean (Phaseolus lunatus L.) protein isolate was hydrolyzed using a sequential pepsin-pancreatin enzymatic system. Hydrolysis was performed to produce limited (LH) and extensive hydr

17. Biological characteristics and probiotic effect of Leuconostoc lactis strain isolated from the intestine of black porgy fish
A strain of lactic acid bacteria, Leuconostoc lactis, was isolated from the intestinal tract of black porgy, Sparus macrocephalus, and identified by conventional biochemical characteristics and 16S rDNA gene sequence analysis. The isolated strain had the ability of bile tolerance and resistance to low pH, and survived well in the trypsinase and pepsin soluti

18. Modelo experimental de simulação de tabagismo e refluxos faringolaríngeo, gastro-esofágico e cancinogênese em ratos Wistar / Experimental model of smoking, gastroesophageal and pharyngolaryngeal reflux and carcinogenesis in Wistar rats
Tabagismo e etilismo são os dois fatores mais importantes na gênese do carcinoma espinocelular do trato aero-digestivo superior (TADS). Outros fatores de risco podem estar envolvidos, como o refluxo faringolaríngeo (RFL). O objetivo desta pesquisa foi testar modelos experimentais de simulação do refluxo faringolaríngeo e gastro-esofágico e modelo de e

19. Bioaccessibility of Calcium and Phosphorus in Milk Samples.
Milk is an essential macro and micronutrients source for growth, development and health, and as one of the animal protein sources for ali age's humans. This work aimed to study in vitro bioaccessibility with simulated gastric digestion in the Ca and P levels in samples of different kind of milk (UHT cow's milk, raw cow's milk, raw sheep milk, UHT goat's milk

20. Infecção de gerbils (Meriones unguiculatus) com Toxocara canis : migração de larvas e estudo morfológico com pesquisa imunohistoquímica de antígenos de larvas nas lesões
Introduction. In last years, the gerbils have been used as experimental model of toxocariasis, especially for studies of ocular lesions and central nervous system. Objectives. To study the migration of larvae and lesions with immunohistochemical study in gerbils infected or re-infected with Toxocara canis. Methods. Gerbils were infected with 1,500 embryonate

21. Molecular mechanisms of Trypanosoma cruzi infection by oral route
Frequent reports on outbreaks of acute Chagas' disease by ingestion of food contaminated with parasites from triatomine insects illustrate the importance of this mode of transmission. Studies on oral Trypanosoma cruzi infection in mice have indicated that metacyclic trypomastigotes invade the gastric mucosal epithelium. A key molecule in this process is gp82

22. Pepsin immobilization into lyophilized chitosan and O-carboxymethilchitosan membranes / Imobilização de pepsina em membranas liofilizadas de quitosana e O-carboximetilquitosana
Enzimas são proteínas utilizadas em processos tecnológicos diversos. Estas enzimas dependendo do tipo e grau de pureza são geralmente caras. Comumente as enzimas exigem controle contínuo do processo no que se refere à temperatura, pH, agitação, entre outros, e após o uso são descartadas, o que torna o custo do processo mais elevado. Em decorrência

23. Efeito da reticulação induzida pela transglutaminase e o glutaraldeido sobre as propriedades das microparticulas obtidas por coacervação complexa / Effect of transglutaminase and glutaraldehyde induced crosslinking on properties of microparticles obtained by complex coacervation
Microparticles were produced by complex coacervation using gelatin and gum Arabic as wall forming materials and a mixture of paprika oleoresin-soy oil (1:10) in a quantity that correspond to 50% of wall material mass. The emulsions production order, gelatin/ paprika oleoresin-soy oil or gum Arabic/paprika oleoresin:soy oil, the crosslinking of the microparti

24. Characterization of cytotoxic heat-stable enterotoxin (ST-L) produced by Escherichia coli isolated from drinking water / Caracterização da enterotoxina citotoxica termoestavel (ST-L) produzida por Escherichia coli isoladas de agua de consumo
Studies on the virulence properties of Escherichia coli associated with intestinal infections are important for the understanding of diarrheic diseases mechanisms. In a previous work we have described a factor presenting enterotoxic and cytotoxic activities in the culture supernatants of E. coli isolated from drinking water in the city of Ouro Preto, MG. Thi
