Supplementation with a Symbiotic Induced Neuroprotection and Improved Memory in Rats with Ischemic Stroke.

After an ischemic stroke, various harmful mechanisms contribute to tissue damage, including the inflammatory response. The increase in pro-inflammatory cytokines has been related to greater damage to the neural tissue and the promotion of neurological alterations, including cognitive impairment. Recent research has shown that the use of prebiotics and/or probiotics counteracts inflammation and improves cognitive function through the production of growth factors, such as brain-derived neurotrophic factor (BDNF), by reducing inflammatory molecules.

Symbiotic Supplementation ( and Agave Inulin) Improves Spatial Memory and Increases Plasticity in the Hippocampus of Obese Rats: A Proof-of-Concept Study.

Obesity has been linked to cognitive impairment through systemic low-grade inflammation. High fat and sugar diets (HFSDs) also induce systemic inflammation, either by induced Toll-like receptor 4 response, or by causing dysbiosis. This study aimed to evaluate the effect of symbiotics supplementation on spatial and working memory, butyrate concentration, neurogenesis, and electrophysiological recovery of HFSD-fed rats.

Memory improvement in senile rats after prebiotic and probiotic supplementation is not induced by GLP-1.

Introduction: The mechanism underlying the memory improvement induced by prebiotic and probiotic supplementation remains unclear. Glucagon-like peptide type 1 (GLP-1) could play an important role since it is induced by prebiotics and enhances memory and learning.

Aims: We correlated the levels of GLP-1 with spatial memory in senile animals to determine its role in memory improvement after prebiotic and probiotic supplementation.

Sarcopenia in chronic liver diseases: a translational overview.

Introduction: Sarcopenia refers to a progressive and generalized muscle mass and strength loss. In liver diseases, it has been related to worse outcomes and high risk of decompensations.

Areas Covered: Sarcopenia is caused by a set of cellular processes in the muscle such as denervation, mitochondrial dysfunction, endotoxemia and inflammation; which are manifested through the alteration of several proteolytic pathways such as lysosomal, proteasomal and caspase systems.

Prebiotics and probiotics as potential therapy for cognitive impairment.

Cognitive functions, such as learning and memory, may be impaired during aging. Age-related cognitive impairment is associated with selective neuronal loss, oxidative changes that lead to microglia activation and neuroinflammation. In addition, it is associated to alteration reduction in trophic factors affecting neurogenesis and synaptic plasticity.

Probiotics and Prebiotics as a Therapeutic Strategy to Improve Memory in a Model of Middle-Aged Rats.

Aging is associated with morphological, physiological and metabolic changes, leading to multiorgan degenerative pathologies, such as cognitive function decline. It has been suggested that memory loss also involves a decrease in neurotrophic factors, including brain-derived neurotrophic factor (BDNF). In recent years, microbiota has been proposed as an essential player in brain development, as it is believed to activate BDNF secretion through butyrate production.

Prehispanic Functional Foods and Nutraceuticals in the Treatment of Dyslipidemia Associated to Cardiovascular Disease: a Mini-Review.

Dyslipidemia is an important modifi able risk factor for cardiovascular and metabolic diseases, which are responsible for a large number of mortality and disability cases around the globe. Different strategies have been used within the treatment of dyslipidemia, including lifestyle modifi cations, pharmacologic therapy, as well as functional foods and nutraceuticals. Functional foods have been used worldwide since ancient times, particularly, the prehispanic civilizations utilized several as medicinal foods.
