Int J Mol Sci 2022 Apr 28;23(9). Epub 2022 Apr 28.

Laboratório de Imunofarmacologia, Instituto Oswaldo Cruz, Fundação Oswaldo Cruz (FIOCRUZ), Rio de Janeiro 21040-900, Brazil.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection, leaving the inflammation process without a proper resolution, leading to tissue damage and possibly sequelae. The central nervous system (CNS) is one of the first regions affected by the peripheral inflammation caused by sepsis, exposing the neurons to an environment of oxidative stress, triggering neuronal dysfunction and apoptosis. Sepsis-associated encephalopathy (SAE) is the most frequent sepsis-associated organ dysfunction, with symptoms such as deliriums, seizures, and coma, linked to increased mortality, morbidity, and cognitive disability.

Structure-activity Relation of Halogenated 2,5-Dimethoxyamphetamines Compared to their α-Desmethyl (2C) Analogues.

FASEB J 2022 May;36 Suppl 1

Division of Clinical Pharmacology & Toxicology, University Hospital Basel, Basel.

Objective And Hypothesis: 4-Substituted derivatives of 2,5-dimethoxyamphetamine (referred to as DOX derivatives) exhibit psychedelic and euphoria-inducing effects, mainly mediated by 5-HT receptor activation; for this reason, they are used recreationally but also bear therapeutic potential. Studies in humans and animals revealed that 4-substitution with halogens results in high clinical potency, which increased with increasing size of the halogen. We therefore hypothesized that increasing size of the halogen substituent results in increased affinity at the 5-HT receptor. Read More

Acute and Chronic Effects of Seizures on Cardiorespiratory Control in the SS Rat.

FASEB J 2022 May;36 Suppl 1

Physiology, Medical College of Wisconsin, Milwaukee, WI.

Epilepsy is a common neurological disorder in which 1/3 of patients experiences repeated seizures, which puts them at greater risk for Sudden Unexpected Death in Epilepsy (SUDEP). The pathophysiological consequences of repeated seizures resulting in SUDEP, including the effects of repeated seizures on cardiorespiratory function, remain unclear. We previously established a rat model (SS rats) in which 10 days of repeated daily audiogenic generalized tonic-clonic seizures (GTCSs) lead to ictal apnea, post-ictal respiratory suppression, blunted chemoreflexes and high spontaneous mortality (PMID: 33232300).
