In the last decade, it has been demonstrated that neurogenesis persists in the adult mammalian brain and that it is induced after insults, where newborn neurons migrate to damaged areas, differentiate and contribute to the recovery. The understanding of the cellular and molecular events involved in this phenomenon could provide effective therapies not only to promote brain repair in stroke or seizures, but also to facilitate functional improvement in depression or Alzheimer. In this context, many advances have been made, such as the implication of different growth factors, membrane receptors, and most importantly diffusible messengers like nitric oxide (NO). We review here studies in both normal and pathophysiological conditions that suggest a dual role for NO in adult neurogenesis and its relation to different pharmacological strategies stimulating neurogenesis.

Predictive role of SLC1A5 in neuroblastoma prognosis and immunotherapy.

Background: Neuroblastoma, a prevalent extracranial solid tumor in pediatric patients, demonstrates significant clinical heterogeneity, ranging from spontaneous regression to aggressive metastatic disease. Despite advances in treatment, high-risk neuroblastoma remains associated with poor survival. SLC1A5, a key glutamine transporter, plays a dual role in promoting tumor growth and immune modulation.

Background: Long-lasting insecticidal nets (LLINs) were once fully effective for the prevention of malaria; however, mosquitoes have developed resistance to pyrethroids, the main class of insecticides used on nets. Dual active ingredient LLINs (dual-AI LLINs) have been rolled out as an alternative to pyrethroid (PY)-only LLINs to counteract this. Understanding the minimum community usage at which these LLINs elicit an effect that also benefits non-users against malaria infection is important.

The decline in estrogen levels is considered as a critical physiological alteration during post-menopause. Fibro/adipogenic progenitors (FAPs) are identified as major contributors to muscular fatty infiltration.

This study explores multi-tasking by examining the effects of transitioning from dual-task to triple-task scenarios. Our research extends beyond conventional dual-task paradigms to investigate the impact of triple-task performance on two participant groups: those unprepared in single, dual, or triple tasks (N = 14) and those previously prepared in single and dual tasks (N = 13). The study consisted of a preparation phase with nine sessions and an assessment phase with eight sessions.
