Sourdough bread enriched with exopolysaccharides and gazpacho by-products modulates in vitro the microbiota dysbiosis.

Sourdough bread enriched with soluble fiber (by in-situ exopolysaccharides production) and insoluble fiber (by gazpacho by-products addition) showed prebiotic effects an in vitro dynamic colonic fermentation performance with obese volunteer's microbiota. Bifidobacterium population was maintained whereas Lactobacillus increased throughout the colonic sections. Conversely, Enterobacteriaceae and Clostridium groups clearly decreased.

Combination of SPE and fluorescent detection of AQC-derivatives for the determination at sub-mg/L levels of biogenic amines in dairy products.

Biogenic amines (BAs) are compounds generated by decarboxylation of their amino acid precursors. Their intake, even at low concentrations, can lead to several types of health problems in sensitive individuals. As they can be easily formed in fermented dairy products, their quantitative determination is very relevant.

Potential of histamine-degrading microorganisms and diamine oxidase (DAO) for the reduction of histamine accumulation along the cheese ripening process.

Lentilactobacillus parabuchneri is the main bacteria responsible for the accumulation of histamine in cheese. The goal of this study was to assess the efficiency of potential histamine-degrading microbial strains or, alternatively, the action of the diamine oxidase (DAO) enzyme in the reduction of histamine accumulation along the ripening process in cheese. A total of 8 cheese variants of cow milk cheese were manufactured, all of them containing L.

Comparison of Peracetic Acid and Chlorine Effectiveness during Fresh-Cut Vegetable Processing at Industrial Scale.

Abstract: This study was conducted to compare the efficacy of two sanitizing agents, chlorine and peracetic acid (PAA), in reducing spoilage and pathogenic microorganisms and disinfection by-products in the washing stage of three types of minimally processed vegetables: iceberg lettuce, carrots, and baby leaves. These fresh-cut products are consumed uncooked; thus, proper sanitation is essential in preventing foodborne illness outbreaks. The comparison was done at industrial scale with equipment already used in the fresh-cut industry and with washers designed and manufactured for this purpose.

Consumption of Sourdough Breads Improves Postprandial Glucose Response and Produces Sourdough-Specific Effects on Biochemical and Inflammatory Parameters and Mineral Absorption.

To evaluate responses to different sourdough breads, six groups of rats were fed a conventional refined wheat bread with no sourdough content (C_WhB); a leavened spelt bread baked with Rebola sourdough (Re_SpB); a durum wheat bread with Rebola sourdough (Re_DuB); or a multigrain bread leavened with Rebola (Re_MGB), Carla (Ca_MGB), or San Francisco sourdough (SF_MGB). Compared to C_WhB-fed rats, Re_SpB-, Re_DuB-, and Re_MGB-fed animals showed lower postprandial blood glucose levels, whereas SF_MGB-fed rats displayed a decreased postprandial blood insulin response and glucose and insulin products. The 3 week intake of Ca_MGB decreased blood triacylglycerols and the relative apparent absorption (RAA) of Fe, Cu, and Zn, whereas Re_MGB-fed animals showed lower serum levels of the MCP-1 inflammatory marker and decreased the Fe RAA.

[Preliminary results of the Spanish Society of Nephrology multicenter study of quality performance measures: hemodialysis outcomes can be improved].

Introduction: The Spanish Society of Nephrology "Quality in Nephrology Working Group" (QNWG) was created in 2002. The aims of this group are the identification, diffusion, implementation and consolidation of a systematic, objective and comprehensive set of quality performance measures (QPMs) to help along the improvement of patient care and outcomes on hemodialysis, by means of strategies of feedback and benchmarking, and the design of quality improvement projects. The objective of this study is to present the preliminary results of a set of quality performance measures obtained in a group of Spanish hemodialysis centers, as well as to evaluate the repercussion of the application of the aforementioned thecniques on the observed results.

[Late nephrology referral influences on morbidity and mortality of hemodialysis patients. A provincial study].

Objective: To evaluate the influence of late referral to nephrology of the patients with chronic renal failure in the morbimortality of the patients who start hemodialysis. SUBJETS AND METHODS: There were included in the study the patients who started hemodialysis (HD) as first form of treatment, and that survived at least three months in both hospitals of reference of the province of Huesca from january 1990 to december 2001. Patients who started HD after acute renal failure were excluded.

Inactivation of Salmonella Senftenberg 775W by ultrasonic waves under pressure at different water activities.

The inactivation of Salmonella Senftenberg 775W by ultrasonic waves (20 kHz, 117 microm) under pressure (175 kPa) treatments at sublethal (manosonication; MS) and lethal temperatures (manothermosonication; MTS) in media of different water activities has been investigated. Heat decimal reduction time values increased up to eighteen fold when the water activity was decreased from >0.99 to 0.

[Study of immutable variables determining rHuEPO dose requirements on hemodialysis patients].

Patients receiving recombinant human erythropoietin (rHuEPO) therapy show wide variability in their responsiveness to the drug. Variables that affect rHuEPO dose requirements can be broadly divided into modificable and immutable characteristics. Most of the scientific research on rHuEPO hyporesponsiveness has focused on modificable variables (iron status, dialysis adequacy), while immutable variables such as gender, etiology of chronic renal failure (CRF) and age have been insufficiently explored.

Comparison of the chlorine inactivation of Yersinia enterocolitica in chlorine demand and demand-free systems.

Inactivation of Yersinia enterocolitica by chlorine (0.6 to 20 ppm) was investigated in distilled water and in tryptic soy broth (TSB, 0.015%) at different temperatures (4, 20, and 40 degrees C).

Membrane damage and microbial inactivation by chlorine in the absence and presence of a chlorine-demanding substrate.

The relationship between cell inactivation and membrane damage was studied in two gram-positive organisms, Listeria monocytogenes and Bacillus subtilis, and two gram-negative organisms, Yersinia enterocolitica and Escherichia coli, exposed to chlorine in the absence and presence of 150 ppm of organic matter (Trypticase soy broth). L. monocytogenes and B.

Inactivation kinetics of Yersinia enterocolitica by citric and lactic acid at different temperatures.

Inactivation of Yersinia enterocolitica by citric (1--20% w/v) and lactic (0.3--4.0% v/v) acids at different temperatures (4, 20, 40 degrees C) has been investigated.

[Huesca and Teruel survey on hemodialysis management].

A cross sectional study was performed in order to evaluate the treatment conditions and medical outcomes among 131 prevalent hemodialysis patients (57% males; mean age 66 +/- 12 years) in Huesca and Teruel. Data were collected at 5 hemodialysis units in Huesca and Teruel. Diabetes mellitus, at 30 percent, was the most common cause of renal insufficiency.

Relationship between inactivation kinetics of a Listeria monocytogenes suspension by chlorine and its chlorine demand.

Kidney allograft biopsy: a valuable tool in assessing the diagnosis of acute rejection.

In order to determine the value of an isolated renal percutaneous biopsy in renal allografts with acute rejection, we studied 17 allograft nephrectomies, in which the histological degree of acute rejection of each of 30 Tru-cut cylinders, were compared with the histological degree of acute rejection diagnosed in 6 large fragments of each kidney considered as a whole. An accurate histological degree of acute rejection was made in 366 cylinders (71.8%).

Ureteral fistula after renal transplantation: the significance of delayed images.

Urinary leakage after renal transplantation is a serious complication that can lead to diagnostic difficulties. A case is reported of urinoma secondary to ureteral fistula characterized in the routine study by a photon-deficient area. Only the image obtained at 6 h allowed a correct diagnosis.
