ng>Background:ng> This work evaluated the capacity of a dry emulsion as a carrier of viable microorganisms with potential use as prophylaxis of infectious diseases. ng>Methods:ng> The aqueous phase containing P. multocida not viable in PBS was emulsified in mineral oil to obtain a w/o emulsion. The microorganisms remained stable and only in two cases (n = 6) did the bacterial concentration decrease. Scanning Electron Microscopy (SEM) revealed a structure of a system with the organized association of particles with cubic symmetry. Using two ex vivo bioadhesion systems, it was demonstrated that the disperse-adsorbed system is capable of adhering to the intestinal mucosa and remains adhered for long periods of time. ng>Results: ng>The no viability of the bacteria in the dry emulsion and the possibility of controlled release were confirmed. In vivo trial was conducted in pigs. It was possible to locate the emulsion and the bacteria attached to the gut of the living animal. An ELISA kit was used to monitor the mean antibody titer of treated pigs over a 2-week period, and a classic primary response curve occurred when the titer was plotted against time. ng>Conclusion: ng>We propose the disperse-adsorbed system as an alternative to commonly used vehicles for immunogens in the oral vaccines.

AIM To examine the association between weekend alcohol consumption and the biochemical and histological alterations at two different concentrations of alcohol in both genders in *** Wistar rats weighing 170-200 g were divided into groups as follows:(1) Control groups; and(2) weekend alcohol-consumption group: 2 d/weekly per 12 wk, at two different concentrations:(1) Group of males or females with a consumption of a solution of alcohol at 40%; and(2) group of males or females with a consumption of a solution of alcohol at 5%. At the end of the experiment, serum and liver samples were obtained. The following enzymes and metabolites were determined in serum: Alanine Aminotransferase(ALT), Aspartate Aminotransferase(AST), Lactate Dehydrogenase, and Gamma-Glutamyltransferase, and glucose, triglycerides, cholesterol, bilirubin, and albumin. Liver samples from each group were employed to analyze morphological abnormalities by light *** In all of the weekend alcohol-consumption groups, AST activity presented a significant, 10-fold rise. Regarding ALT activity, the groups with weekend alcohol consumption presented a significant increase that was six times greater. Bilirubin levels increased significantly in both groups of females. We observed a significant increase in the parameters of fatty change and inflammation due to weekend alcohol consumption. Only the group of females that consumed alcohol at 40% presented slight hepatocel ular disorganization COnCLUSIOn The results obtained herein provide solid evidence that weekend alcohol consumption gives rise to liver damage, demonstrated by biochemical and histological alterations, first manifested acutely, and prolonged weekend alcohol consumption can cause greater, irreversible damage.

AIM: To explore methylation of DAPK, THBS1, CDH-1, and p14 genes, and Helicobacter pylori(H. pylori) status in individuals harboring esophageal columnar ***: Distal esophageal mucosal samples obtained by endoscopy and histologically diagnosed as gastric-type(non-specialized) columnar metaplasia, were studied thoroughly. DnA was extracted from paraffin blocks, and methylation status of deathassociated protein kinase(DAPK), thrombospondin-1(THBS1), cadherin-1(CDH1), and p14 genes, was examined using a methyl-sensitive polymerase chain reaction(MS-PCR) and sodium bisulfite modification protocol. H. pylori cag A status was determined by ***: In total, 68 subjects(33 females and 35 males), with a mean age of 52 years, were included. H. pylori cag A positive was present in the esophageal gastric-type metaplastic mucosa of 18 individuals. DAPK, THSB1, CDH1, and p14 gene promoters were methylated by MS-PCR in 40(58.8%), 33(48.5%), 46(67.6%), and 23(33.8%) cases of the 68 esophageal samples. H. pyloristatus was associated with methylation of DAPK(P = 0.003) and THBS1(P = 0.019).COnCLUSIOn: DnA methylation occurs in cases of gastric-type(non-specialized) columnar metaplasia of the esophagus, and this modification is associated with H. pylori cag A positive infection.
