Antidepressant and Antiaging Effects of Açaí ( Mart.) in Mice.

Depression is a mental disorder that affects 300 million people of all ages worldwide, but fewer than half of those with the condition receive adequate treatment. In addition, the high pharmacological refractoriness (affecting 30%-50% of patients) and toxicity of some classical antidepressants support the pursuit of new therapies. People with this condition show depressed mood, loss of pleasure, high levels of oxidative stress, and accelerated biological aging (decreased telomere length and expression of the telomerase reverse transcriptase (TERT), the enzyme responsible for telomere maintenance).

Aqueous Coriandrum sativum L. extract promotes neuroprotection against motor changes and oxidative damage in rat progeny after maternal exposure to methylmercury.

This study aimed to investigate the effects of Coriandrum sativum aqueous extract (CSAE) on the rat progeny of mothers exposed to methylmercury (MeHg). The presence of bioactive compounds and CSAE's antioxidant capacity been evaluated, and the offspring were assessed for their total mercury levels, motor behavioral parameters and oxidative stress in the cerebellum. The analysis of the bioactive compounds revealed significant amounts of polyphenols, flavonoids, and anthocyanins, as well as a variety of minerals.

Large-scale projects in the amazon and human exposure to mercury: The case-study of the Tucuruí Dam.

The Tucuruí Dam is one of the largest dams ever built in the Amazon. The area is not highly influenced by gold mining as a source of mercury contamination. Still, we recently noted that one of the most consumed fishes (Cichla sp.

Antidepressant drugs in convulsive seizures: Pre-clinical evaluation of duloxetine in mice.

Convulsive seizures (CS) are deleterious consequences of acute cerebral insults and prejudicial events in epilepsy, affecting more than 50 million people worldwide. Molecular mechanisms of depression and epilepsy include an imbalance between excitatory and inhibitory neurotransmission provoking oxidative stress (OS). OS is intimately linked to the origin and evolution of CS and is modulated by antidepressant and anticonvulsant drugs.

Anticonvulsant properties of Euterpe oleracea in mice.

Açai (Euterpe oleracea Mart.), a highly consumed fruit in Amazon, is from a common palm with remarkable antioxidant properties. Because oxidative stress and seizures are intimately linked, this study investigated the potential neuroprotective and anticonvulsant effects of commercial clarified açai juice (EO).
