Effect of Rosmarinus officinalis on Mental Disorder Symptoms in Incarcerated People and Prison Workers

Introduction: common mental disorders whose symptoms are not early identified can turn into more serious illnesses, such as depression, anxiety, and mood disorder. The literature presents the use of rosemary as a form of treatment of physical and mental illnesses, including depression. Objective: The objective of this study was to evaluate the effects of treatments with different doses of rosemary (Rosmarinus officinalis) extract on symptoms of Common Mental Disorders (CMD) in incarcerated people and prison workers. Methods: This is a randomized, double-blind, placebo-controlled clinical trial study. The intervention was carried out using rosemary extract doses at 100, 500, and 1000 mg day-1 in groups composed of 10 participants, for 3 months. A 20-item self-reporting questionnaire (SRQ-20) was used to assess the presence of CMD. The project was submitted and approved by the Research Ethics Committee under the number 4,973,589. Results: The treatments with rosemary extract at 500 and 1000 mg day-1 showed statistically significant results for reducing CMD symptoms when compared to the those found at the beginning of the research. Conclusion: The use of rosemary extract was effective to reduce CMD in the evaluated prison staff and incarcerated people, especially when used at doses of 500 and 1000 mg day-1, and presented safety, as the participants did not experience side effects.

A simulação da biomassa de aveia por elementos climáticos, nitrogênio e regulador de crescimento / The simulation of the oat biomass by climatic elements, nitrogen and growth regulator

A produção de biomassa de aveia voltada à elaboração de silagem de qualidade é dependente de elementos climáticos e nitrogênio sem ocorrência de acamamento. O objetivo do presente estudo é a definição da dose ideal do regulador de crescimento que possibilite, no máximo, 5% de acamamento de plantas de aveia, bem como a identificação das variáveis potenciais para composição do modelo de regressão linear múltipla com simulação da produtividade de biomassa à elaboração de silagem nas condições de uso do regulador, em reduzida, alta e muito alta fertilização com nitrogênio. O estudo foi conduzido em 2013, 2014 e 2015, em delineamento de blocos ao acaso, com quatro repetições em esquema fatorial 4x3, para doses de regulador (0, 200, 400 e 600mL ha-1) e doses de nitrogênio (30, 90 e 150kg ha-1), respectivamente. A dose de 495mL ha-1 de regulador se mostra eficiente na redução do acamamento de plantas de aveia em condição de reduzida, alta e muito alta fertilização com nitrogênio. A soma térmica, a precipitação, a radiação, a dose de regulador e o nitrogênio qualificam a composição do modelo de regressão linear múltipla, tornando eficiente a simulação da produtividade de biomassa da aveia para silagem ao longo do ciclo.(AU)

The production of oat biomass focused on the development of quality silage is dependent on climatic elements and nitrogen without lodging occurrence. The objective of the study is to define the optimal dose of growth regulator that allows a maximum of 5% oat plant lodging and identify potential variables for composition of multiple linear regression model with productivity simulation of biomass to the preparation of silage in the conditions of low, high and very high fertilization with nitrogen. The study was conducted in 2013, 2014, and 2015 in the randomized block design with four replications in a factorial 4x3, for regulator doses (0, 200, 400 and 600ml ha-1) and nitrogen doses (30, 90 and 150kg ha-1), respectively. The dose of 495mL ha-1 regulator is efficient in reducing the oat plant lodging in condition reduced, high, and very high fertilization with nitrogen. Thermal time, precipitation, radiation, regulator dose and nitrogen dose qualify the composition of the multiple linear regression model, making efficient the biomass oat productivity simulation for silage over the cycle.(AU)
