Ketamine-induced neurotoxicity in neurodevelopment: A synopsis of main pathways based on recent experimental findings.

Ketamine, a phencyclidine derivative and -methyl-D-aspartate (NMDA) receptor antagonist, is widely used as an anesthetic, analgesic, and sedative agent in daily pediatric practice. Experimental studies have suggested that early prenatal or postnatal exposure to ketamine can induce neuroapoptosis, and establish neurobehavioral deficits that are evident in adulthood. However, most of the currently available clinical evidence is derived from retrospective and observational clinical studies.

Effects of gestational thiamine-deprivation and/or exposure to ethanol on crucial offspring rat brain enzyme activities.

Objective: The fetal alcohol spectrum disorder (FASD) is a group of clinical conditions associated with the exposure to ethanol (EtOH). We have recently examined the effects of a moderate maternal exposure to EtOH on crucial brain enzyme activities in offspring rats, and discussed the translational challenges arising when attempting to simulate any of the clinical conditions associated with FASD.

Materials And Methods: In this current study, we: (i) address the need for a more consistent and reliable experimental platform that could simulate milder cases of FASD complicated by simultaneous thiamine-deprivation during gestation and (ii) explore the effects of such a moderate maternal exposure pattern to EtOH and a thiamine-deficient diet (TDD) on crucial enzyme activities in the offspring rat brains.

Cranberry: A Promising Natural Source of Potential Nutraceuticals with Anticancer Activity.

Studies have shown that cranberry and its components may exert anticancer properties. The present study aims to critically summarise the existing experimental studies evaluating the potential effects of cranberry on cancer prevention and treatment. PubMed database was searched to identify relevant studies.

Non-genetic therapeutic approaches to Canavan disease.

Canavan disease (CD) is a rare leukodystrophy characterized by diffuse spongiform white matter degeneration, dysmyelination and intramyelinic oedema with consequent impairment of psychomotor development and early death. The molecular cause of CD has been identified as being mutations of the gene encoding the enzyme aspartoacylase (ASPA) leading to its functional deficiency. The physiological role of ASPA is to hydrolyse N-acetyl-l-aspartic acid (NAA), producing l-aspartic acid and acetate; as a result, its deficiency leads to abnormally high central nervous system NAA levels.
