Effects of dietary iron supplementation on reproductive performance of sows and growth performance of piglets.

This experiment aimed to investigate the effects of dietary iron supplementation from different sources on the reproductive performance of sows and the growth performance of piglets. A total of 87 sows with similar farrowing time were blocked by body weight at day 85 of gestation, and assigned to one of three dietary treatments (n = 29 per treatment): basal diet, basal diet supplemented with 0.2% ferrous sulfate (FeSO4), and basal diet supplemented with 0.

Effects of dietary supplementation of different levels of gamma-aminobutyric acid on reproductive performance, glucose intolerance, and placental development of gilts.

This study aimed to investigate the effects of dietary gamma-aminobutyric acid (GABA) supplementation on reproductive performance, glucose intolerance, and placental development of gilts during mid-late gestation. Based on the principle of backfat thickness consistency, 124 gilts at 65 d of gestation were assigned to three dietary groups: CON (basic diet, n = 41), LGABA (basic diet supplemented with 0.03% GABA, n = 42), and HGABA (basic diet supplemented with 0.

Retinoic Acid-PPARα Mediates β-Carotene Resistance to Placental Dysfunction Induced by Deoxynivalenol.

Deoxynivalenol (DON), one of the most polluted mycotoxins in the environment and food, has been proven to have strong embryonic and reproductive toxicities. However, the effects of DON on placental impairment and effective interventions are still unclear. This study investigated the effect of β-carotene on placental functional impairment and its underlying molecular mechanism under DON exposure.

-derived butyrate mediates protection of high fermentable fiber against placental inflammation in gestational diabetes mellitus.

Inflammation-associated insulin resistance is a key trigger of gestational diabetes mellitus (GDM), but the underlying mechanisms and effective interventions remain unclear. Here, we report the association of placental inflammation (tumor necrosis factor-α) and abnormal maternal glucose metabolism in patients with GDM, and a high fermentable dietary fiber (HFDF; ) could reduce GDM development through gut flora-short-chain fatty acid-placental inflammation axis in GDM mouse model. Mechanistically, HFDF increases abundances of and butyrate, reduces placental-derived inflammation by enhancing gut barrier and inhibiting the transfer of bacterial-derived lipopolysaccharide, and ultimately resists high-fat diet-induced insulin resistance.

Gut Microbiota Mediates Alleviation of Deoxynivalenol-Induced Anorexia.

Deoxynivalenol (DON) is a widespread mycotoxin and causes anorexia and emesis in humans and animals; GG (LGG), a well-characterized probiotic, can improve intestinal barrier function and modulate immune response. Currently, it is unclear whether LGG has a beneficial effect on DON-induced anorexia. In the present study, mice were treated with DON, LGG, or both by gavage for 28 days to evaluate the effects of LGG on DON-induced anorexia.

Cysteamine and -Acetyl-cysteine Alleviate Placental Oxidative Stress and Barrier Function Damage Induced by Deoxynivalenol.

Sows are highly sensitive to deoxynivalenol (DON) and susceptible to reproductive toxicity caused by oxidative stress, but the potential mechanisms and effective interventions remain unclear. Here, we investigated the role of two antioxidants (cysteamine and -acetyl-cysteine) in regulating the reproductive performance, redox status, and placental barrier function of sows and their potential mechanisms under DON exposure. Maternal dietary supply of antioxidants from day 85 of gestation to parturition reduced the incidence of stillbirths and low-birth-weight piglets under DON exposure.

Lactobacillus rhamnosus GG ameliorates DON-induced intestinal damage depending on the enrichment of beneficial bacteria in weaned piglets.

Background: Deoxynivalenol (DON) is one of the most common environmental pollutants that induces intestinal inflammation and microbiota dysbiosis. Lactobacillus rhamnosus GG (LGG) is a probiotic that not only has anti-inflammatory effects, but also shows protective effect on the intestinal barrier. However, it is still unknown whether LGG exerts beneficial effects against DON-induced intestinal damage in piglets.

Dihydroartemisinin alleviates deoxynivalenol induced liver apoptosis and inflammation in piglets.

Deoxynivalenol (DON) is one of the mycotoxins that contaminate cereals and feed, thereby endangering human and animal health. Dihydroartemisinin (DHA), a derivative of artemisinin, has anti-inflammatory and antioxidant functions in addition to anti-malaria and anti-cancer. The purpose of this study was to investigate the effects of DHA on alleviating liver apoptosis and inflammation induced by DON in piglets.

GG ameliorates deoxynivalenol-induced kidney oxidative damage and mitochondrial injury in weaned piglets.

Deoxynivalenol (DON) is a common mycotoxin that pollutes food crops and adversely affects the health of animals, even humans. GG (LGG) can alleviate intestinal injury, and anti-inflammatory and antioxidant effects. However, the potential of LGG in alleviating kidney injury induced by DON in piglets remains to be studied.

Deoxynivalenol exposure induces liver damage in mice: Inflammation and immune responses, oxidative stress, and protective effects of Lactobacillus rhamnosus GG.

Deoxynivalenol (DON), one of the most common environmental pollutants, substantially affects human and animal health. Much attention has been paid to the ability of probiotics to modulate inflammation and immune responses. In this work, the toxic effects of DON on the liver and the protective effects of Lactobacillus rhamnosus GG (LGG) were investigated.

[Effects of different annealing conditions on the photoluminescence of nanoporous alumina film].

The nanoporous alumina films were prepared by two-step anodic oxidation in 0.5 mol L-1 oxalic acid electrolyte at 40 V. Photoluminescence (PL) of nanoporous alumina films was investigated under different annealing atmosphere and different temperature.
