CyberKnife Radiosurgery for refractory bilateral trigeminal neuralgia. Case report.

Unlabelled: Case description: A case of a 37-year-old female patient suffering from refractory bilateral trigeminal neuralgia is presented, who underwent various interventions such as acupuncture, block therapies and even microvascular decompression without effective pain relief.

Clinical Findings: Paresthesias and shooting-like twinges of pain intensity 10/10 in bilateral maxillary and mandibular branches of the trigeminal nerve, with nasal and intraoral triggers that made eating impossible, becoming increasingly severe since refractoriness to microvascular decompression and carbamazepines, triggering the twinges even during sleep, generating somnolence, depressive mood and social isolation.

Treatment And Results: The patient was evaluated by an interdisciplinary neuro-oncology team, where, in accordance with the analysis of the brain magnetic resonance imaging and the patient's history, it was indicated to perform Cyberknife® radiosurgery in monofraction on the left trigeminal and subsequently treat the contralateral trigeminal.

Toxicity and expression of oxidative stress genes in Tribolium castaneum induced by toluene, xylene, and thinner.

Thinner is a solvent that contains toluene, xylene, and other substances. The aim of this study was to examine the toxicity of thinner, xylene, and toluene on adult red flour beetles, Tribolium castaneum (Herbst), as well as the effects of thinner and toluene on gene expression. The major compounds identified in the thinner with peak area >2% were p-xylene (6%), toluene (4%), 2,4-dimethylheptane (3%), methylcyclohexane (2.

Neurotoxic Effects of Linalool and β-Pinene on Tribolium castaneum Herbst.

Effective, ethical pest control requires the use of chemicals that are highly specific, safe, and ecofriendly. Linalool and β-pinene occur naturally as major constituents of the essential oils of many plant species distributed throughout the world, and thus meet these requirements. These monoterpenes were tested as repellents against , using the area preference method, after four hours of exposure and the effect transcriptional of genes associated with neurotransmission.

Toxicity of Naphthalene and Benzene on Tribollium castaneum Herbst.

Naphthalene and benzene are widely-used volatile organic compounds. The aim of this research was to examine the toxicological effects of naphthalene and benzene against as an animal model. Adult insects were exposed to these aromatic compounds to assess mortality after 4-48 h of exposure.

Air mercury contamination in the gold mining town of Portovelo, Ecuador.

Portovelo is one of the oldest gold mining towns in Ecuador. Artisanal gold mining still uses mercury in the process of gold recovery. In this study, mercury concentrations in the air of Portovelo were evaluated.
