1. The anxiolytic effect of cannabidiol depends on the nature of the trauma when patients with post-traumatic stress disorder recall their trigger event
Objectives: We assessed whether administering cannabidiol (CBD) before recalling the traumatic event that triggered their disorder attenuates anxiety in patients with post-traumatic stress disorder (PTSD). As an exploratory pilot analysis, we also investigated whether this effect depends on the nature of the event (sexual vs. nonsexual trauma). Methods: Thi

2. Cortical Reorganization Following Psychoeducational Counselling and Residual Inhibition Therapy (RIT) in Individuals with Tinnitus
Abstract Introduction Psychoeducational counselling and residual inhibition therapy (RIT) are traditional approaches used in many clinics to manage tinnitus. However, neurophysiological studies to evaluate posttreatment perceptual and functional cortical changes in humans are scarce. Objectives The present study aims to explore whether cortical auditory-ev

3. Cesarean effects on adolescents’ birth experiences: counterfactual analysis
Abstract Introduction The birth experience of adolescents is understudied even though they are a particularly vulnerable population to experience a negative birth event, given that they exhibit many known risk factors. Objective To ascertain whether a cesarean birth mediates the impact of infant complications on the birth experience of adolescent mothers.

4. Blood pressure control for diabetic retinopathy
BACKGROUND: Diabetic retinopathy is a common complication of diabetes and a leading cause of visual impairment and blindness. Research has established the importance of blood glucose control to prevent development and progression of the ocular complications of diabetes. Simultaneous blood pressure control has been advocated for the same purpose, but findings

5. Reduced dietary salt for the prevention of cardiovascular disease
BACKGROUND: This is an update of a Cochrane review that was first published in 2011 of the effects of reducing dietary salt intake, through advice to reduce salt intake or low-sodium salt substitution, on mortality and cardiovascular events.OBJECTIVES: 1. To assess the long-term effects of advice and salt substitution, aimed at reducing dietary salt, on mort

6. Single event transients in logic circuits - load and propagation induced pulse broadening
The generation and propagation of single event transients (SET) in logic gate chains is studied and modeled. Regarding SET generation, we investigate the dependence of the generated SET pulse width on the struck node capacitance. Rising node capacitance may lead to amplified pulse width, indicating that increasing load capacitance alone is not an option for

7. Analysis of transistor sizing and folding effectiveness to mitigate soft errors / Análise da influência do dimensionamento e partição de transistores e na proteção de circuitos contra efeitos de radiação
Este trabalho apresenta uma avaliação da eficiência do dimensionamento e particionamento (folding) de transistores para a eliminação ou redução de efeitos de radiação. Durante o trabalho foi construído um modelo de transistor tipo-n MOSFET para a tecnologia 90nm, utilizando modelos preditivos. O transistor 3D modelado foi comparado com o modelo de

8. SimulaÃÃo do Desgaste Abrasivo via InteraÃÃes MÃltiplas / Using Multiple Interactions to Simulate Abrasive Wear
Abrasive wear is currently classified according to different particle dynamics: a) the sliding of active particles on the sample surface and b) the rolling of abrasives between the surfaces. The prevailing particle dynamics depends on the system features. In this thesis, instrumented laboratory tests are used to present a new methodology for the simulation o

9. Effect of PvrR and RcsB response regulators in motility, biofilm formation and their connection with Pseudomonas aeruginosa PA14 CupD fimbria / Efeito dos reguladores de resposta PvrR e RcsB na motilidade, formação de biofilme e sua relação com a fímbria CupD de Pseudomonas aeruginosa PA14
Pseudomonas aeruginosa is a γ-proteobacteria that can behave as an opportunistic pathogen. The strain PA14 carries two pathogenicity islands, the largest of them, PAPI-1, contains two gene clusters between two direct repeat sequences that are transcribed in opposite directions and are involved in virulence. The first group consists of four genes arrange

10. Effects of Trypanosoma brucei tryptophanyl-tRNA synthetases silencing by RNA interference
The kinetoplast genetic code deviates from the universal code in that 90% of mitochondrial tryptophans are specified by UGA instead of UGG codons. A single nucleus-encoded tRNA Trp(CCA) is used by both nuclear and mitochondria genes, since all kinetoplast tRNAs are imported into the mitochondria from the cytoplasm. To allow decoding of the mitochondrial UGA

11. Níveis e origem da acidificação das chuvas na região do Rio Grande, RS
The current article presents the first data on physical-chemical parameters of wet precipitation collected at single collection point in the city of Rio Grande, during the period of 12 months in 1997-1998. The employed technique of rainwater separation into several portions made clear the process of the atmosphere self-purification during a precipitation eve

12. Directed Evolution of Metabolic Pathways in Microbial Populations. I. Modification of the Acid Phosphatase Ph Optimum in S. CEREVISIAE
An experimental system for directing the evolution of enzymes and metabolic pathways in microbial populations is proposed and an initial test of its power is provided.—The test involved an attempt to genetically enhance certain functional properties of the enzyme acid phosphatase in S. cerevisiae by constructing an environment in which the functional chang
