Abstract
Mitochondrial dysfunction plays a key role in the development of neurodegenerative disorders. In contrast, the regulation of the endocannabinoid system has been shown to promote neuroprotection in different neurotoxic paradigms. The existence of an active form of the cannabinoid receptor 1 (CB1R) in mitochondrial membranes (mitCB1R), which might exert its effects through the same signaling mechanisms as the cell membrane CB1R, has been shown to regulate mitochondrial activity. Although there is evidence suggesting that some cannabinoids may induce protective effects on isolated mitochondria, substantial evidence on the role of cannabinoids in mitochondria remains to be explored. In this work, we developed a toxic model of mitochondrial dysfunction induced by exposure of brain mitochondria to the succinate dehydrogenase inhibitor 3-nitropropionic acid (3-NP). Mitochondria were also pre-incubated with the endogenous agonist anandamide (AEA) and the synthetic CB1R agonist WIN 55212-2 to evaluate their protective effects. Mitochondrial reduction capacity, reactive oxygen species (ROS) formation, and mitochondrial swelling were assessed as toxic markers. While 3-NP decreased the mitochondrial reduction capacity and augmented mitochondrial ROS formation and swelling, both AEA and WIN 55212-2 ameliorated these toxic effects. To explore the possible involvement of mitCB1R activation on the protective effects of AEA and WIN 55212-2, mitochondria were also pre-incubated in the presence of the selective CB1R antagonist AM281, which completely reverted the protective effects of the cannabinoids to levels similar to those evoked by 3-NP. These results show partial protective effects of cannabinoids, suggesting that mitCB1R activation may be involved in the recovery of compromised mitochondrial activity, related to reduction of ROS formation and further prevention of mitochondrial swelling.

Abstract
Neurodegenerative disorders, such as Parkinson's and Alzheimer's diseases, have olfaction impairment. These pathologies have also been linked to environmental pollutants. Vanadium is a pollutant, and its toxic mechanisms are related to the production of oxidative stress. In this study, we evaluated the effects of inhaled vanadium on olfaction, the olfactory bulb antioxidant, through histological and ultrastructural changes in granule cells. Mice in control group were made to inhale saline; the experimental group inhaled 0.02-M vanadium pentoxide (V2O5) for 1 hr twice a week for 4 weeks. Animals were sacrificed at 1, 2, 3, and 4 weeks after inhalation. Olfactory function was evaluated by the odorant test. The activity of glutathione peroxidase (GPx) and glutathione reductase (GR) was assayed in olfactory bulbs and processed for rapid Golgi method and ultrastructural analysis. Results show that olfactory function decreased at 4-week vanadium exposure; granule cells showed a decrease in dendritic spine density and increased lipofuscin, Golgi apparatus vacuolation, apoptosis, and necrosis. The activity of GPx and GR in the olfactory bulb was increased compared to that of the controls. Our results demonstrate that vanadium inhalation disturbs olfaction, histology, and the ultrastructure of the granule cells that might be associated with oxidative stress, a risk factor in neurodegenerative diseases.

Abstract
The extracts prepared from the stem barks of several Mexican copalchis species, including Hintonia latiflora, Exostema caribaeum and a commercial mixture of Hintonia standleyana and E. caribaeum (CM) showed significant hypoglycemic and antihyperglycemic effects. The extracts were tested in three different in vivo models using normal and streptozotocin (STZ)-induced diabetic rats. From the active extract of H. latiflora, 25-O-acetyl-3-O-beta-D-glucopyranosyl-23,24-dihydrocucurbitacin F (1), an analog of 23,24-dihydrocucurbitacin F, and several known compounds (2-8) were isolated; cucurbitacin 1 was also isolated from H. standleyana. Oral administration of H. latiflora extract [100mg/kg of body weight (bw)] and 5-O-beta-D-glucopyranosyl-7,3',4'-trihydroxy-4-phenylcoumarin (5) (30 mg/kg of bw) to STZ-induced diabetic rats, for a 30 day duration, restored blood glucose levels to normal values. The groups treated either with the active principle 5, or the extract of H. latiflora, showed less body weight loss than glibenclamide-treated and diabetic control groups (p<0.05). It was also demonstrated that the extract of H. latiflora regulated hepatic glycogen and plasma insulin levels (p<0.05). These data suggest that its antihyperglycemic effect is due in part to stimulation of insulin secretion and regulation of hepatic glycogen metabolism.
