Observational prospective study on Lactobacillus plantarum P 17630 in the prevention of vaginal infections, during and after systemic antibiotic ther…

2018

We performed a prospective cohort parallel observational study on the use of Lactobacillus plantarum P 17630 in the prevention of vaginal infections. Eligible were women with a diagnosis of bacterial vaginosis (15 days) and documented history of recurrent vaginal infections; and/or cystitis (15 days); and/or treatment with antibiotics for bacterial respiratory tract infections during the week before the study entry. Study subjects were prescribed Lactobacillus plantarum P 17630  100.000.000 UFC one vaginal capsule per day for 6 days, then a capsule per week for 16 weeks. Eligible subjects were enrolled in two parallel cohorts: 85 women using (group A) and 39 not using (group B) Lactobacillu…

Preventive Effect of Cow's Milk Fermented with Lactobacillus paracasei CBA L74 on Common Infectious Diseases in Children: A Multicenter Randomized Co…

2017

Background: Fermented foods have been proposed to prevent common infectious diseases (CIDs) in children attending day care or preschool. Objectives: To investigate the efficacy of dietary supplementation with cow’s skim milk fermented with the probiotic Lactobacillus paracasei CBA L74 in reducing CIDs in children attending day care or preschool. Methods: Multicenter, randomized, double-blind, placebo-controlled trial on healthy children (aged 12–48 months) consuming daily 7 grams of cow’s skim milk fermented with L. paracasei CBA L74 (group A), or placebo (maltodextrins group B) attending day care or preschool during the winter season. The main outcome was the proportion of children who exp…

Fermentation of Nocellara Etnea table olives by functional starter cultures at different low salt concentrations

2018

Nocellara Etnea is one of the main Sicilian cultivars traditionally used to produce both olive oil and naturally fermented table olives. In the present study, the effect of different salt concentrations on physico-chemical, microbiological, sensorial, and volatile organic compounds (VOCs) formation was evaluated in order to obtain functional Nocellara Etnea table olives. The experimental design consisted of 8 treatments as follow: fermentations at 4, 5, 6, and 8% of salt with (E1-E4 samples) and without (C1-C4 samples) the addition of starters. All the trials were carried out at room temperature (18 +/- 2 degrees C) and monitored for an overall period of 120 d. In addition, the persistence …

Gut microbiota and aging-A focus on centenarians.

2020

Gut microbiota (GM) is a dynamic organ throughout the lifespan. Aging is a complex process that comprises a plethora of mechanisms such as senescence, immunosenescence and inflammaging, representing important pathways of age-related diseases. GM structure could both influence and be influenced by aging occurring changes within the host. A unique category of long living individuals exists, namely centenarians that have the outstanding capacity to adapt to various challenges. Longevity seems to be associated with certain GM which, among other factors, might render individuals more resistant to age-related diseases and subsequently to long living. Diet, prebiotics, probiotics and synbiotics ma…

Th17 skewing in the GALT of a Crohn disease patient upon Lactobacillus rhamnosus GG consumption.

2015

We wish to report on a recent observation we made and that might represent a useful hint for the employment of the so called probiotics in the management of some pathological immune reactions of the gut. By analyzing GALT-associated T cells upon consumption of L. rhamnosus-GG, we obtained some hints that probiotics might have locoregional immunological effects mainly when administered in patients with IBDs rather than in individuals with non-inflamed gut mucosa.

Functional Foods: Product Development, Technological Trends, Efficacy Testing, and Safety

2020

Functional foods is a very popular term in the social and scientific media; consequently, food producers have invested resources in the development of processed foods that may provide added functional benefits to consumers’ well-being. Because of intrinsic regulation and end-of-use purposes in different countries, worldwide meanings and definitions of this term are still unclear. Hence, here we standardize this definition and propose a guideline to attest that some ingredients or foods truly deserve this special designation. Furthermore, focus is directed at the most recent studies and practical guidelines that can be used to develop and test the efficacy of potentially functional foods an…

Influence of probiotic microorganisms on aflatoxins B 1 and B 2 bioaccessibility evaluated with a simulated gastrointestinal digestion

2018

Aflatoxins (AFs) are produced mainly by the molds Aspergillus flavus and Aspergillus parasiticus. Aflatoxin B1 (AFB1) is classified as carcinogenic to humans. The aim of this study was to evaluate the capacity of different strains of Lactobacilli (Lb.) and Bifidobacteria (Bf.) to reduce the bioaccessibility of AFB1 and aflatoxin B2 (AFB2), spiked in loaf bread, using a dynamic in vitro simulated gastrointestinal digestion system. Aliquots of 20 mL of gastric and duodenal fluids were sampled for the determination of the mycotoxins gastric and duodenal bioaccessibility respectively, by liquid-chromatography coupled to the mass spectrometry in tandem (LC–MS/MS). A reduction of AFs bioacc…

A NOVEL APPROACH IN COLORECTAL CANCER AND DIABETES MANAGEMENT: ROLE OF METFORMIN AND RAPAMYCIN

Abstract The link between colorectal cancer (CRC), diabetes mellitus (DM) and inflammation is well established, and polytherapy, including rapamycin, has been commonly adopted. However, due to the relatively weak response of CRC to rapamycin, combination with other molecules including metformin has become a potentially promising approach. This study is a novel approach that aimed at assessing the effect of a combination therapy of metformin and rapamycin on the control or prevention of colorectal cancer in diabetic animals, in presence or absence of probiotics. Fifty NOD/SCIDs male mice developed xenograft by inoculating HCT116 cells into the flank; they were equally divided into diabetics …

Administration of a Synbiotic to Free-Living Elderly and Evaluation of Serum Cytokines. A Pilot Study

2010

Ten free-living elderly were administered with a synbiotic [fermented milk containing Lactobacillus rhamnosus Gorbach and Goldin (LGG)] and oligofructose as a prebiotic for one month. Serum cytokines were evaluated before (T(0)) and after (T(1)) synbiotic administration. At T(0), values of Interleukin (IL)-12, IL-6, IL-10, IL-1beta and Tumor Necrosis Factor (TNF)-alpha were lower than normal controls, with the exception of IL-8, thus confirming previous results on the impairment of both innate and adaptive responses in elderly. At T(1), the synbiotic was able to significantly increase, depressed values of IL-1, IL-6 and IL-8 with a trend to a modest increase for the restant cytokines. In co…
