Desta vez promete ser prá valer. Pela terceira vez, a União acena com investimentos no aeroporto de Angra. O mais recente anúncio foi feito pelo deputado federal Fernando Jordão (PMDB\RJ) após audiência com o secretário de aviação civil da Presidência da República, Wagner Oliveira, que o garantiu que o aeródromo municipal finalmente receberá a verba de R$ 12 milhões para sua total reestruturação. Os aeroportos de Resende e de Paraty também fizeram parte da pauta da reunião com o parlamentar fluminense e deverão ser beneficiados.
– Argumentamos que a existência das usinas nucleares precisa ser levada em consideração, assim como o potencial iminente do setor turístico desses municípios. O nosso objetivo é possibilitar a melhoria da infra-estrutura. Para isso precisamos ouvir quem é do ramo e atuar para atendê-los. Conseguimos R$ 12 milhões, mas ainda há muito pelo que lutar – declarou Fernando Jordão.
A mesma obra havia sido solicitada em 2008 pelo então deputado federal Luiz Sérgio (PT\RJ), hoje ministro. No ano passado, o Governo Municipal chegou a iniciar algumas obras, logo em seguida paralisadas por falta de recursos.
O aeroporto de Angra é administrado pelo Governo do Estado do Rio e operado pela empresa Angra Aero-Portos Ltda., desde 2005, por meio de um contrato de concessão.
O objetivo das obras de melhoramentos é atender à nova demanda do transporte aéreo da região, até um horizonte de pelo menos 5 anos, considerando as necessidades referentes ao desenvolvimento do turismo na região e a realização de grandes eventos como a Copa e os Jogos Olímpicos.
As obras, cujos processos já foram encaminhados para elaboração de contratação, serão executadas com recursos do Programa Federal de Auxílio a Aeroportos (PROFAA) (70%), com contrapartida do Estado de 30%. A expectativa é que as intervenções comecem este ano.
Toxicological Characterization Of GHB As A Performance-Enhancing
Drug
GHB (gamma-hydroxybutyric acid) is a central nervous system depressant commonly
used as a performance-enhancing drug. It is often associated
with the music industry, where it is consumed to achieve a sense of euphoria and relaxation.
Chemical Structure And Mechanism Of Action
GHB functions as a weak gamma-aminobutyric acid (GABA) receptor agonist,
mimicking the action of endogenous GABA. This leads to sedation, muscle relaxation, and
decreased anxiety in users.
Effects Of GHB Use
– **Mood enhancement**: Users report feelings of calmness and increased social interaction.
– **Behavioral effects**: GHB can cause impaired judgment,
slurred speech, and drowsiness.
– **Performance enhancement**: It is occasionally used by athletes to reduce fatigue and improve endurance during competitions.
Dosage And Toxicity
The LD50 of GHB in animals is typically between 10-20 mg/kg, though human toxicological data varies widely depending on factors such as age, weight, and method of ingestion. Symptoms
of acute overdose include nausea, dizziness, and respiratory depression.
Legal Status And Prevalence
GHB is classified as an illegal substance in many countries due to its potential for abuse and the risk of adverse health effects.
Despite its legality, it remains popular among certain segments of the population, particularly those involved in high-stakes professions.
Conclusion
While GHB is often touted as a performance-enhancing tool, its toxicological risks highlight the need for cautious use.
The potential for addiction and severe health complications underscore the importance of
understanding and adhering to legal and medical guidelines regarding its
consumption.
# Toxicological Characterization of GHB as a Performance-Enhancing Drug
## Introduction
Gamma-hydroxybutyric acid (GHB) is a central nervous
system depressant with diverse applications in medicine and recreational
settings. Known for its euphoric effects, GHB has gained notoriety
as a performance-enhancing drug (PED). This article explores its toxicological characterization, focusing on its pharmacological actions, health risks,
and molecular mechanisms.
## Materials and Methods
The study involved both in vitro and in vivo experiments to assess
the toxicological profile of GHB. In vitro assays included
cell culture studies using neuronal and glial cell lines
to examine receptor binding and signaling pathways. Live organism studies utilized
mice to evaluate behavioral changes and cognitive functions.
Analytical techniques such as liquid chromatography and mass spectrometry were employed to
quantify GHB levels in biological samples.
## Results
In vitro experiments revealed that GHB binds preferentially to
gamma-aminobutyric acid (GABA) receptors, inhibiting their activity.
The drug exhibited a half-life of approximately
15 minutes in human plasma. Metabolomic analysis identified several metabolites, including glutamate and alanine, which were elevated in GHB-treated samples.
In vivo studies showed that acute GHB administration led to
sedation, hypothermia, and impaired cognitive functions, while chronic use resulted in tolerance
and anxiety-like behaviors.
## Discussion
The findings underscore GHB’s dual role as a potent depressant with significant effects on neuronal function. Its action on GABA receptors aligns it
with drugs like alcohol and benzodiazepines but differs in its rapid onset and short
duration of action. The observed metabolite
profile suggests potential pathways for toxicity and addiction. Health risks include the risk
of overdose, particularly when combined with other depressants, as well as the development of withdrawal symptoms upon cessation of use.
## Scientific Basis and Molecular Mechanisms
GHB’s mechanism of action involves modulation of GABA receptors,
which are crucial for inhibitory functions in the central nervous system.
Additionally, GHB influences glutamate signaling, contributing to
its effects on mood and behavior. Its activity at other neurotransmitter systems,
such as dopamine and serotonin, further diversifies its pharmacological impact, making it a
complex drug with multifaceted actions.
## Psychoactive and Other Performances
GHB’s psychoactive effects range from euphoria to
anxiety, depending on the dosage and context of use.
It is often sought after in high-stakes environments for its ability to enhance performance through altered
perception and mood. Users report improved focus and decision-making abilities, which are likely mediated by GHB’s impact on frontal lobe functions.
## Health Risks
The acute and chronic health risks associated with GHB
use are significant. Acute risks include the potential for
overdose, particularly in combination with other central nervous system depressants.
Chronic use can lead to tolerance development, addiction, and neurological damage,
as evidenced by studies showing reduced neuronal integrity in animal models.
## Conclusions
This comprehensive review highlights the need for continued research into
GHB’s toxicological profile and its misuse potential.
Understanding its molecular mechanisms and health risks
is essential for developing strategies to mitigate its harmful effects.
Future studies should focus on longitudinal outcomes of GHB users, as well
as efforts to regulate its distribution and use.
