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.

Copolymer-1 as a potential therapy for mild cognitive impairment.

Mild cognitive impairment (MCI) is a prodromal stage of memory impairment that may precede dementia. MCI is classified by the presence or absence of memory impairment into amnestic or non-amnestic MCI, respectively. More than 90% of patients with amnestic MCI who progress towards dementia meet criteria for Alzheimer's disease (AD).

Spinal cord injury-induced cognitive impairment: a narrative review.

Spinal cord injury is a serious damage to the spinal cord that can lead to life-long disability. Based on its etiology, spinal cord injury can be classified as traumatic or non-traumatic spinal cord injury. Furthermore, the pathology of spinal cord injury can be divided into two phases, a primary injury phase, and a secondary injury phase.

Nelson Syndrome: A Case Report and Literature Review.

Objective: Nelson syndrome (NS) is a rare clinical disorder that can occur after total bilateral adrenalectomy (TBA), performed as a treatment for Cushing disease. NS is defined as the accelerated growth of an adrenocorticotropic hormone-producing pituitary adenoma. Our objective is to describe a case of NS and discuss it based on existing knowledge of this syndrome.

Effect of overweight and obesity on cognitive function in children from 8 to 12 years of age: a descriptive study with a cross-sectional design.

Introducción: el sobrepeso y la obesidad en la infancia y la adolescencia se han incrementado progresivamente durante los últimos años. Además de las comorbilidades conocidas, la obesidad se ha relacionado con un bajo rendimiento escolar en todas las edades, asociándose a alteraciones cognitivas. Objetivo: determinar la diferencia que existe en la función cognitiva de unos niños de 8 a 12 años con normopeso, sobrepeso u obesidad.

[A septal rupture of atypical location after myocardial infarction. A clinical case].

Paciente masculino de 46 años de edad con antecedentes personales de hipertensión arterial sistémica, tabaquismo y etilismo y heredofamiliares de hipertensión arterial sistémica. El padecimiento inició con cuadro de astenia, adinamia, disnea progresiva, edema de miembros inferiores y aumento del volumen abdominal, por lo que acudió con el médico, quien decidió hospitalizarlo. El paciente recibió tratamiento médico con captopril, furosemida y espironolactona, sin mejoría de los síntomas, motivo por el cual se lo refirió a la institución de los autores.

Immunization with neural-derived peptides increases neurogenesis in rats with chronic spinal cord injury.

Aims: Immunization with neural-derived peptides (INDP) has demonstrated to be a promising therapy to achieve a regenerative effect in the chronic phase of the spinal cord injury (SCI). Nevertheless, INDP-induced neurogenic effects in the chronic stage of SCI have not been explored.

Methods And Results: In this study, we analyzed the effect of INDP on both motor and sensitive function recovery; afterward, we assessed neurogenesis and determined the production of cytokines (IL-4, IL-10, and TNF alpha) and neurotrophic factors (BDNF and GAP-43).

Use of a Combination Strategy to Improve Morphological and Functional Recovery in Rats With Chronic Spinal Cord Injury.

Immunization with neural derived peptides (INDP), as well as scar removal (SR) and the use of matrices with bone marrow-mesenchymal stem cells (MSCs), have been studied separately and proven to induce a functional and morphological improvement after spinal cord injury (SCI). Herein, we evaluated the therapeutic effects of INDP combined with SR and a fibrin glue matrix (FGM) with MSCs (FGM-MSCs), on motor recovery, axonal regeneration-associated molecules and cytokine expression, axonal regeneration (catecholaminergic and serotonergic fibers), and the induction of neurogenesis after a chronic SCI. For this purpose, female adult rats were subjected to SCI, 60 days after lesion, rats were randomly distributed in four groups: (1) Rats immunized with complete Freund's adjuvant + PBS (vehicle; PBS-I); (2) Rats with SR+ FGM-MSCs; (3) Rats with SR+ INDP + FGM-MSCs; (4) Rats only with INDP.

Selective endovascular cooling for stroke entails brain-derived neurotrophic factor and splenic IL-10 modulation.

Stroke poses a serious health and economic burden, and the lack of treatment options necessitates a viable therapy. Hypothermia represents a promising stroke therapy, yet side effects of full-body cooling, such as pneumonia, limit its clinical application. Selective endovascular cooling (SEC), via infusion of cold saline through the intraarterial artery, represents an attractive alternative by locally cooling the brain while preserving body temperature.

Stand alone or join forces? Stem cell therapy for stroke.

Introduction: Stroke is a major cause of mortality and disability with a narrow therapeutic window. Stem cell therapy may enhance the stroke recovery.

Areas Covere: Regenerative medicine via stem cells stands as a novel therapy for stroke.
