Perspective: Of Mice and Men - How Widespread Is Adult Neurogenesis?
(Frontiers Media, 2019-08-29)
These are exciting times for research on adult hippocampal neurogenesis (AHN). Debate and controversy regarding the existence of generation of new neurons in the adult, and even diseased human brain flourishes as articles ...
Identification of ncRNAs as Potential Therapeutic Targets in Multiple Sclerosis Through Differential ncRNA – mRNA Network Analysis
(Biomed Central, 2015-03-28)
Background: Several studies have revealed a potential role for both small nucleolar RNAs (snoRNAs) and microRNAs (miRNAs) in the physiopathology of relapsing-remitting multiple sclerosis (RRMS). This potential implication ...
Delayed Diagnosis of an Eating Disorder in a Male Patient With Superior Mesenteric Artery Syndrome: Results From a Case Study
(Frontiers Media, 2019-10-15)
Background: Eating disorders (EDs) are serious and life-threatening mental diseases characterized by abnormal or altered eating habits. The prevalence is variable, being influenced by diverse sociocultural factors. ...
Myotonic Dystrophy type 1 cells display impaired metabolism and mitochondrial dysfunction that are reversed by metformin
(Impact Journals, 2020-04-15)
Myotonic dystrophy type 1 (DM1; MIM #160900) is an autosomal dominant disorder, clinically characterized by progressive muscular weakness and multisystem degeneration. The broad phenotypes observed in patients with DM1 ...
Loss of Dmrt5 Affects the Formation of the Subplate and Early Corticogenesis
(Oxford University Press, 2020-05)
Dmrt5 (Dmrta2) and Dmrt3 are key regulators of cortical patterning and progenitor proliferation and differentiation. In this study, we show an altered apical to intermediate progenitor transition, with a delay in SP ...
Impacto de la estimulación subtalámica a largo plazo sobre la situación cognitiva de los pacientes con enfermedad de Parkinson avanzada
(Elsevier, 2019-06-13)
Objetivo
El objetivo es evaluar los efectos de la estimulación cerebral profunda del núcleo subtalámico bilateral (STN-DBS) sobre el estado cognitivo de los pacientes con enfermedad de Parkinson 5 años después de la ...
Circadian glucocorticoid oscillations preserve a population of adult hippocampal neural stem cells in the aging brain
(Springer, 2019-06-20)
A decrease in adult hippocampal neurogenesis has been linked to age-related cognitive impairment. However, the mechanisms involved in this age-related reduction remain elusive. Glucocorticoid hormones (GC) are important ...
Myelin imaging and characterization by magnetic resonance imaging
(2019-12-13)
Los axones neuronales están recubiertos de una membrana lipídica llamada mielina, que protege a los axones y posibilita una transmisión rápida y eficiente del impulso eléctrico. En ciertas patologías como la lesión cerebral ...
Phenotypical and functional heterogeneity of neural stem cells in the aged hippocampus
(Wiley, 2019-08)
Adult neurogenesis persists in the hippocampus of most mammal species during postnatal and adult life, including humans, although it declines markedly with age. The mechanisms driving the age-dependent decline of hippocampal ...
Inicio y progresión de la enfermedad de Parkinson: papel de la activación GLIAL
(2020-03-17)
La enfermedad de Parkinson (EP) se caracteriza por un déficit de dopamina en el estriado debido a la degeneración de neuronas dopaminérgicas en la sustancia negra pars compacta (SNpc) que proyectan al estriado. El marcador ...
