Exploring the Effects of an Alfalfa Leaf-Derived Adsorbent on Microbial Community, Ileal Morphology, Barrier Function, and Immunity in Turkey Poults during Chronic Aflatoxin B Exposure.

This article follows-up on our recently published work, which evaluated the impact of the addition of an alfalfa leaf-derived adsorbent in the aflatoxin B (AFB)-contaminated diet in regard to the production parameters, blood cell count, serum biochemistry, liver enzymes, and liver histology of turkey poults. This paper presents complementary results on microbial community, ileal morphology, barrier function, and immunity. For this purpose, 350 1-day-old female turkey poults were randomly distributed into five groups: (1) Control, AFB-free diet; (2) AF, AFB-contaminated diet at 250 ng/g; (3) alfalfa, AFB-free diet + 0.

Assessment of the Impact of Humic Acids on Intestinal Microbiota, Gut Integrity, Ileum Morphometry, and Cellular Immunity of Turkey Poults Fed an Aflatoxin B-Contaminated Diet.

A recent study published data on the growth performance, relative weights of the organs of the gastrointestinal tract, liver histology, serum biochemistry, and hematological parameters for turkey poults fed an experimental diet contaminated with aflatoxin B (AFB) and humic acids (HA) extracted from vermicompost. The negative effects of AFB (250 ng AFB/g of feed) were significantly reduced by HA supplementation (0.25% /), suggesting that HA might be utilized to ameliorate the negative impact of AFB from contaminated diets.

Efficacy of powdered alfalfa leaves to ameliorate the toxic effects of aflatoxin B in turkey poults.

This experiment was conducted to determine the effect of an adsorbent material based on powdered alfalfa leaves added in the aflatoxin B (AFB)-contaminated diet of turkey poults on production parameters, blood cell count, serum biochemistry, liver enzymes, and liver histology. For this purpose, three hundred and fifty female Nicholas-700 poults were randomly assigned into five treatments: (1) Control, AFB-free diet; (2) AF, diet contaminated with 250 ng AFB/g; (3) Alfalfa, AFB-free diet + 0.5% (w/w) adsorbent; (4) AF+alfalfa, diet contaminated with 250 ng AFB/g + 0.

Evaluation of the efficacy of humic acids to counteract the toxic effects of aflatoxin B1 in turkey poults.

This study aims to evaluate the efficacy of humic acid (HA) from worm compost as an adsorbent for aflatoxin B (AFB) in turkey poults. The experiment involved the inclusion of 0.25% (w/w) HA in the diet of turkey poults consuming aflatoxin-contaminated feed (250 ng AFB/g).

Mitigation of AFB-Related Toxic Damage to the Intestinal Epithelium in Broiler Chickens Consumed a Yeast Cell Wall Fraction.

experiments were conducted to evaluate the effectiveness of a yeast cell wall fraction (YCW) to reduce the negative impact of aflatoxin B (AFB) to the intestinal epithelium in broiler chickens. Zeta potential (ζ-potential), point of zero charge (pH), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) techniques were used to characterize the YCW. Two hundred one-day-old male Ross 308 broiler chickens were randomly allocated into four treatments: (1) control, chickens fed an AFB-free diet; (2) AF, chickens feed an AFB-contaminated diet (500 ng AFB/g); (3) YCW, chickens fed an AFB-free diet + 0.

Lactoferrin and Its Derived Peptides: An Alternative for Combating Virulence Mechanisms Developed by Pathogens.

Due to the emergence of multidrug-resistant pathogens, it is necessary to develop options to fight infections caused by these agents. Lactoferrin (Lf) is a cationic nonheme multifunctional glycoprotein of the innate immune system of mammals that provides numerous benefits. Lf is bacteriostatic and/or bactericidal, can stimulate cell proliferation and differentiation, facilitate iron absorption, improve neural development and cognition, promote bone growth, prevent cancer and exert anti-inflammatory and immunoregulatory effects.

Expression in algae of a chimeric protein carrying several epitopes from tumor associated antigens.

Immunotherapies for cancer treatment constitute promising avenues to fight this global health issue. Algae can be used as both biofactories and delivery vehicles of vaccines; having low cost, fast growth, enhanced safety, and adjuvant effects as advantages. In the present study a multiepitope protein, called BCB, was designed as an attractive approach to develop new cancer immunotherapies.

The effect of moderate-dose aflatoxin B and Salmonella Enteritidis infection on intestinal permeability in broiler chickens.

The effect of dietary aflatoxin B (AFB) and Salmonella Enteritidis infection on intestinal permeability was investigated. Two hundred 1-day-old male Ross 308 broiler chickens were randomly divided into 4 treatments of 5 replicates each (10 birds per replicate), which were fed ad libitum for 3 weeks with the following treatments: control, chickens fed an AFB-free diet; AF, chickens fed an AFB-contaminated diet at 470 ng/g; SE, chickens fed an AFB-free diet and challenged with 10 cfu of S. Enteritidis per bird at 18 days old; AF + SE, chickens fed an AFB-contaminated diet and challenged with 10 cfu of S.

Mitochondrial activity in different regions of the brain at the onset of streptozotocin-induced diabetes in rats.

Diabetes affects a variety of tissues including the central nervous system; moreover, some evidence indicates that memory and learning processes are disrupted. Also, oxidative stress triggers alterations in different tissues including the brain. Recent studies indicate mitochondria dysfunction is a pivotal factor for neuron damage.

[Atrial functional mitral regurgitation. Three-dimensional echocardiographic study].

Introduction And Objectives: Atrial fibrillation can lead to left atrium remodelling and induce functional mitral regurgitation. The aim of this study is to establish those features of the mitral annulus that are related to atrial functional mitral regurgitation.

Methods: A total of 29 patients with persistent atrial fibrillation and 36 controls in sinus rhythm were retrospectively enrolled.

[General profile of the nutrition surplus in Mexico from 1990-2013: An approach using the energy supplied by macronutrients and food groups].

This text analyzes the evolution of the excessive food energy supply in Mexico from 1990 to 2013. For each year, the energy and macronutrient requirements of the Mexican population were estimated and contrasted with the per capita energy supply. Discrepancies between requirement and supply were analyzed as a time series.

A comparative study of classroom and online distance modes of official vocational education and training.

The study discussed in this paper had two principal objectives. The first was to evaluate the distance model of official vocational education and training offered by means of a virtual learning platform. The second was to establish that both on-site classroom and online distance modes of vocational education and training can be seen as complementary in terms of responding to the majority of modern educational needs.
