In vitro studies support the existence of adult neural stem cells in the rostral migratory stream (RMS). The evidence supporting this possibility in vivo is scarce. We then explore this issue by taking advantage of a rat model in which a physical barrier implanted in the brain interrupted the migration of neuroblasts derived from the SVZ along the RMS at(More)
BACKGROUND The legal framework and funding mechanisms of the national health research system were recently reformed in Mexico. A study of the resource allocation for health research is still missing. We identified the health research areas funded by the National Council on Science and Technology (CONACYT) and examined whether research funding has been(More)
Birth-enucleated rodents display enlarged representations of whiskers (i.e., barrels of the posteromedial subfield) in the primary somatosensory cortex. Although the historical view maintains that barrel expansion is due to incremental increases in neuronal activity along the trigeminal pathway during postnatal development, recent evidence obtained in(More)
BACKGROUND The bulge region of the hair follicle contains resident epithelial stem cells (SCs) that are activated and mobilized during hair growth and after epidermal wounding. However, little is known about the signals that modulate these processes. Clinical and experimental observations show that a reduced supply of sensory innervation is associated with(More)
Blindness leads to a major reorganization of neural pathways associated with touch. Because incoming somatosensory information influences motor output, it is plausible that motor plasticity occurs in the blind. In this work, we evaluated this issue at the peripheral level in enucleated rats. Whisker muscles in enucleated rats 160 days of age or older showed(More)
Innervation is required to preserve several aspects of skin homeostasis. Previous studies in rodents have shown that sciatic nerve transection leads to epidermal thinning and reduced keratinocyte proliferation. As the sciatic nerve is composed of sensory and motor axons, it is not clear whether skin alterations reflect motor or sensory disturbances. In this(More)
Circulating microRNAs (miRNAs) and the functional implications of miRNAs contained in extracellular vesicles (EVs) have gained attention in the last decade. Little is known about the regulation of the abundance of plasma miRNAs in response to chronic ingestion of carbohydrates. Therefore, we explored the circulating levels of miR-21, miR-146a, miR-155, and(More)
