The Impact of Cannabidiol Treatment on Anxiety Disorders: A Systematic Review of Randomized Controlled Clinical Trials.

Generalized Anxiety Disorder (GAD) is a common psychiatric condition characterized by persistent and excessive worry, often accompanied by dysautonomic symptoms that significantly impact patients' well-being. Cannabidiol (CBD), a non-psychoactive compound derived from cannabis, has shown potential as an anxiolytic through its partial agonism of the 5HT-1A receptor and its negative allosteric modulation of CB1 receptors, which may help mitigate the anxiogenic effects of tetrahydrocannabinol (THC). This study evaluates the impact of CBD on individuals diagnosed with various anxiety disorders, comparing its effects to placebo and conventional pharmaceutical treatments through a systematic review of randomized controlled trials (RCTs).

Mycorrhizal fungi arbuscular in organic and conventional sugarcane systems.

Organic production systems are increasingly gaining market share; however, there are still few studies on their influence on the activity of soil microorganisms in sugarcane. Arbuscular mycorrhizal fungi are extremely sensitive to environmental changes, and their activity can be used as a parameter of comparison and quality between organic and conventional systems. The objective of this work was to evaluate mycorrhizal activity in different varieties of sugarcane under two production systems.

The effect of water molecules on paraquat salts: from physicochemical properties to environmental impact in the Brazilian Cerrado.

The green revolution model that is followed in the Brazilian Cerrado is dependent on mechanization, chemical fertilization for soil dressing and correction, and the use of herbicides. Paraquat is a methyl viologen herbicide marketed as bipyridylium dichloride salts and used (in low doses) to combat weeds in their post-emergence stage. It is a non-selective pesticide that causes the peroxidation of the lipids that make up the cell membrane, and when it comes into contact with foliage, it results in the death of the plant.

Arbuscular mycorrhizal fungi in the soil using cover crops with and without nitrogen addition.

This study aimed to evaluate the occurrence of mycorrhizal fungi and glomalin content in soil under different cover crops with and without the application of nitrogen in the cover. The following cover plants were used: Crotalaria juncea ( L.), wild beans from Ceará ( Mart.

Mycorrhizal fungi arbuscular in forage grasses cultivated in Cerrado soil.

The Cerrado is one of the most important regions for agricultural development in the world and is the main productive breadbasket of the Americas. One of the main agricultural activities in the region is high-tech livestock. Cerrado soils are predominantly low in fertility, and arbuscular mycorrhizal fungi play a fundamental role in plant nutrition in this biome.

Resistance of soil to penetration as a parameter indicator of subsolation in crop areas of sugar cane.

Sugarcane is a very important economic crop that relies heavily on agricultural machinery, which contributes to soil compaction and a consequent decline in productivity. Subsoiling operation reduces the problems caused by compression; however, it is necessary to know its location and intensity. Accordingly, the aim of this work is to present a compression diagnostic method based on soil resistance to penetration as the parameter that indicates need for intervention in the subsoil.

Seasonal Variation in Mycorrhizal Community of Different Cerrado Phytophysiomies.

Understanding the dynamics of mycorrhizal fungi in the Cerrado is fundamental for the adoption of conservation practices and for understanding the resilience of this biome in relation to long periods of drought. Thus, this work aimed to verify the dynamics of the mycorrhizal population in five phytophysiognomies of the Cerrado biome. The samples were taken from the Chapada dos Veadeiros National Park, a permanent preservation with native Cerrado vegetation without any anthropic influence.

Flavonoids from Brazilian Cerrado: Biosynthesis, Chemical and Biological Profile.

Flavonoids are highly bioactive compounds with very low toxicity, which makes them attractive starting points in drug discovery. This study aims to provide information on plant species containing flavonoids, which are found in the Brazilian Cerrado. First, we present the characterization and plant diversity with emphasis on the families of flavonoid-producing plants, and then we describe the phenylpropanoid pathway which represents the flavonoids' main route biosynthesis-generally conserved in all species.

The cerrado of Goiás in the literature of Bernardo Élis, from a viewpoint of environmental history.

This article analyzes the representations of nature in the literature of Bernardo Élis based on the theoretical and methodological assumptions of environmental history. Élis was part of a group of intellectuals whose literature presented the living conditions in the frontier of Goiás and the human relationships occurring in these landscapes. In these scrublands, the dramas of their characters are mixed with the physical environment of the cerrado region in a realistic narrative denouncing the living conditions in this isolated frontier area.
