An intervention protocol supported by virtual reality technology has been developed. This protocol allows simulating work environments in which workers face psychosocial risk factors to identify and transform their emotional states and improve their health and work performance. A detailed literature review was done to identify situations that are threatening their mental health in the work environment and are susceptible to simulation using virtual reality. The protocol and the technological tool were validated in a company in the construction sector in Santa Marta, Colombia, showing a good acceptance by the workers. These positively valued this option compared to traditional alternatives for aspects of training in identifying and evaluating different situations that could threaten their mental health. It can be indicated that virtual reality is an effective technological tool to promote, prevent and intervene psychosocial risk factors.

This study assessed the effect of protected nitrate on methane emissions, energy utilization, and nitrogen balance in Brangus steers. Nine housed steers were assigned to one of three treatments that differed in a non-protein nitrogen source: urea (control), protected nitrate (NP), and free nitrate (NL). The experiment was performed in three periods by using a 3x3 Latin square design repeated three times. No animal showed signs of nitrate intoxication. NP steers reduced the intake and digestibility of dry matter, protein, and gross energy. Dietary nitrates reduced methane production by 23%. Nitrate levels of 3% in dry matter were safe for steer diets. In conclusion, the nitrate protection method presented here reduced dry matter intake, nitrogen retention, digestibility, and energy utilization efficiency.

The main purpose of this research study is to conduct a phytochemical characterization of leaf and trichome extracts of Cnidoscolus urens (L.) Arthur collected in the Municipality of Cucuta (Norte de Santander, Colombia). C. urens is a plant known in Cucuta as “pringamoza,” it is abundant and it is often reported as a common native weed found in tropical dry forest. Ethanolic extracts are prepared by separate maceration of 59.9 grams of leaves and 3.1 grams of trichomes, both previously treated by lipholization. Extracts were then concentrated at reduced pressure (50rpm, 150mbar, and 40°C). The results showed that the leaf’s extract yield was 34.18%. The secondary metabolites identified in C. urens were triterpenes, steroids, coumarins, flavonoids, cardiotonics, and cyanogenic glycosides. Some of these have important biological activities. It is concluded that C. urens from Norte de Santander is a plant species with great potential as a source of secondary metabolites for industrial applications and for traditional ethnobotanical medicine.
