Effects of Valproic Acid Embryonic Exposure on Zebrafish: A Systematic Review and Meta-Analysis.

Exposure to valproic acid (VPA) during embryogenesis has become a valuable tool for modeling neurodevelopmental disorders in animal models such as zebrafish (). This article examines the effects of embryonic exposure to VPA in zebrafish on the basis of 39 articles sourced from PubMed and Google Scholar. We conducted a systematic review and meta-analysis to elucidate the common impacts of VPA exposure and reported that VPA significantly altered development at various levels.

Current Opinion on the Use of c-Fos in Neuroscience.

For years, the biochemical processes that are triggered by harmful and non-harmful stimuli at the central nervous system level have been extensively studied by the scientific community through numerous techniques and animal models. For example, one of these techniques is the use of immediate expression genes, which is a useful, accessible, and reliable method for observing and quantifying cell activation. It has been shown that both the gene and its protein c-Fos have rapid activation after stimulus, with the length of time that they remain active depending on the type of stimulus and the activation time depending on the stimulus and the structure studied.

Effects of environmental enrichment and sexual dimorphism on the expression of cerebellar receptors in C57BL/6 and BTBR + Itpr3tf/J mice.

Objective: Environmental enrichment is used to treat social, communication, and behavioral deficits and is known to modify the expression of synaptic receptors. We compared the effects of environmental enrichment in the expression of glutamate and endocannabinoid receptors, which are widely expressed in the cerebellar cortex. These two receptors interact to regulate neuronal function and their dysregulation is associated with behavioral changes.

Razor scrape assay, an alternative variation to wound and healing assays.

Cell migration is the process by which cells move through tissues, and it is crucial to carry out a wide variety of physiological and pathological processes. The study methods to evaluate cell migration are very useful tools for biomedical research. Among these methods, the wound and healing assay is one of the simplest, most economical and is widely used in research.

[Obesity as a risk factor in the development of cancer].

According to the World Health Organization, every year about 3.4 million adults die of consequences related to overweight or obesity. People with a Body Mass Index above 30 are more likely to express certain diseases, including some types of cancer.

Rehabilitating a brain with Alzheimer's: a proposal.

Alzheimer's disease (AD) is the most common neurodegenerative disorder, originating sporadically in the population aged over 65 years, and advanced age is the principal risk factor leading to AD development. In spite of the large amount of research going on around the globe and all the information now available about AD, there is still no origin or triggering process known so far. Drugs approved for the treatment of AD include tacrine, donepezil, rivastigmine, galantamine, and memantine.
