Anandamide (AEA) is a lipid mediator that participates in the regulation of several reproductive functions. This study investigated the endocannabinoid system in normal (NP) and preeclamptic (PE) placentas, and analyzed the potential functional role of AEA in the regulation of nitric oxide synthesis. The protein expression and localization of NAPE-PLD, FAAH and CB1 receptor were analyzed in nor...

BACKGROUND Functional dyspepsia (FD) is a common functional gastrointestinal disease, and abdominal pain is one of the main symptoms. The aim of this study was to explore the effects and mechanisms of auricular electro-acupuncture (AEA) on gastric hypersensitivity in a rodent model of FD. METHODS Ten-day-old pups were gavaged with 0.2 ml of 0.1% iodoacetamide daily for 6 days. AEA at the "sto...

PURPOSE To evaluate whether high intraocular pressure (IOP)-induced ischemia is associated with modifications in the retinal endocannabinoid metabolism and to ascertain whether drugs that interfere with the endocannabinoid system may prevent retinal damage due to ischemic insult. METHODS Anandamide (AEA) synthesis, transport, hydrolysis, and AEA endogenous levels were assessed by means of hig...

BACKGROUND Anandamide (AEA) is an endogenous lipid mediator that exerts several effects in the brain as well as in peripheral tissues. These effects are mediated mainly by two types of cannabinoid receptors, named CB(1)R and CB(2)R, making AEA a prominent member of the "endocannabinoid" family. Also immune cells express CB(1) and CB(2) receptors, and possess the whole machinery responsible for ...

According to the Centers for Disease Control and Prevention, the incidence of inflammatory bowel diseases (IBD) is about 1 in 250 people in the United States. The disease is characterized by chronic or recurring inflammation of the gut. Because of the localization of the endocannabinoid system in the gastrointestinal tract, it may be a potential pharmacologic target for the treatment of IBD and...

Nitric oxide production, catalyzed by nitric oxide synthase (NOS), should be strictly regulated to allow embryo implantation. Thus, our first aim was to study NOS activity during peri-implantation in the rat uterus. Day 6 inter-implantation sites showed lower NOS activity (0.19±0.01 pmoles L-citrulline mg prot(-1) h(-1)) compared to days 4 (0.34±0.03) and 5 (0.35±0.02) of pregnancy and to day 6...

The endocannabinoid system is known to have positive effects on depression partly through its actions on neurotrophins, such as Brain-Derived Neurotrophic Factor (BDNF). As BDNF is also considered the major candidate molecule for exercise-induced brain plasticity, we hypothesized that the endocannabinoid system represents a crucial signaling system mediating the beneficial antidepressant effect...
