Exposure to anandamide on young rats causes deficits in learning, temporal perception and induces changes in NMDA receptor expression.

Human use of marijuana at an early age has been reported to lead to cognitive impairment. However, researchers have not yet clearly determined whether this impairment is due to marijuana-induced alterations in the developing nervous system and whether this deficit persists into adulthood after marijuana use has ceased. We administered anandamide to developing rats to assess the effect of cannabinoids on development.

The mediating role of emotion regulation strategies in the relationship between family of origin violence and intimate partner violence.

The effects of family of origin violence and intimate partner violence have been extensively documented; however, very few studies have examined the interaction with emotion regulation strategies. Thus, the objective of this research was to analyze whether different types of emotion regulation strategies, both adaptive and maladaptive, mediate the relationship between family of origin violence and intimate partner violence in the Mexican population. A total of 838 participants (45.

c-Fos immunoreactivity in the hypothalamus and reward system of young rats after social novelty exposure.

Socialization is an adaptive behavior during the early stages of life because it helps young animals become independent and determines healthy adult social behavior. Therefore, it is probable that the brain areas involved in the processing of social stimuli are more sensitive to social novelty during early life stages. To test this hypothesis, four groups of young male rats were exposed to different socioenvironmental stimuli; nonsocial physical novelty, social familiarity, social novelty, and a control group which received no stimulation.

Hormonal State Comparison (Progesterone, Estradiol, and Leptin) of Body Fat and Body Mass Indices in Mexican Women as a Risk Factor for Neonatal Physiologic Condition.

Study Objective: Describe the impact of teen pregnancy on later ovarian activity and metabolic hormones considering the concentration of current levels of ovarian steroids and leptin in a sample of Mexican females.

Design: Cross-sectional study in the maternity of the General Hospital of Atlacomulco and campus of the Autonomous University of the State of Mexico.

Participants: 71 women between the ages of 18 and 24, and 160 neonates seen between March 2010 and June 2012.

[Food habits of the white-tailed deer, Odocoileus virginianus (Artiodactyla: Cervidae) in Nanchititla Natural Park, Mexico].

White-tailed deer is a species with a large behavioral plasticity and adaptation to different habitats, including their food habits. This study was conducted with the aim to determine the food habits of this species in the cloud (BMM) and pine-oak (BPE) forests. Deer scats and plant samples were obtained following standard methods, from Sierra Nanchititla Park in the State of Mexico, from June 1990 to May 1992.
