Anxiolytic Effects of Indole Alkaloids From Rauvolfia ligustrina in Adult Zebrafish: Involvement of the GABAergic and 5‐HT Systems

Chemistry &Biodiversity, EarlyView.
ABSTRACT Benzodiazepines are widely used in the treatment of anxiety, but their use may be interrupted due to side effects. This study evaluated the indole alkaloids isocarapanaubine (indole alkaloid 1 [AIN1]) and 18‐β‐hydroxy‐3‐epi‐α‐yohimbine (indole alkaloid 2 [AIN2]), extracted from Rauvolfia ligustrina, in adult zebrafish.

Genetic Downregulation of GABA_B Receptors from Oligodendrocyte Precursor Cells Protects Against Demyelination in the Mouse Spinal Cord

Cells
GABAergic signaling and GABAB receptors play crucial roles in regulating the physiology of oligodendrocyte-lineage cells, including their proliferation, differentiation, and myelination.

Decreased GABA receptor in the cerebral cortex of epileptic rats: effect of Bacopa monnieri and Bacoside-A

Journal of Biomedical Science, 2012
Abstact Background Gamma amino butyric acid (GABA), the principal inhibitory neurotransmitter in the cerebral cortex, maintains the inhibitory tones that counter balances neuronal excitation. When this balance is perturbed, seizures may ensue. Methods In

NSAIDS AS MODULATORS OF CATION CHANNELS: FENAMATES REPURPOSING IN CHANNELOPATHIES

ChemMedChem, Accepted Article.
Cationic ion channels are transmembrane proteins that regulate the flux of cations (potassium, sodium, and calcium) across cell membrane, playing a pivotal role in many cellular functions. Disruptions of their activity can lead to the so‐called genetic or acquired channelopathies, a heterogeneous group of diseases that affect multiple human systems ...

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

The Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

The Mammalian Interaural Time Difference Detection Circuit Is Differentially Controlled by GABAB Receptors during Development [PDF]

, 2010
Throughout development GABAB receptors (GABABRs) are widely expressed in the mammalian brain. In mature auditory brainstem neurons, GABABRs are involved in the short-term regulation of the strength and dynamics of excitatory and inhibitory inputs, thus ...

Synthesis of Substituted Imidazo[1,2‐a]pyridines, Imidazo[1,2‐a]pyrazines and Imidazo[1,2‐b]pyridazines by Multicomponent Reactions Using Green Solvents

European Journal of Organic Chemistry, EarlyView.
In an environmentally friendly process for synthesizing heterocyclic molecules of therapeutic interest, imidazo[1,2‐a]pyridine, imidazo[1,2‐a]pyrazine and imidazo[1,2‐b]pyridazine core structures are obtained by a multicomponent Groebke–Blackburn–Bienaymé reaction using bio‐based recyclable solvents.

Interaction of hypothalamic GABA\u3csub\u3eA\u3c/sub\u3e and excitatory amino acid receptors controlling heart rate in rats [PDF]

, 1991
We have previously shown that microinjection of drugs that impair gamma-aminobutyric acid (GABA)-mediated synaptic inhibition into the dorsomedial hypothalamus (DMH) of rats generates cardiovascular and behavioral changes that mimic the response to ...

Activation of GABA_B receptors inhibits protein kinase B /Glycogen Synthase Kinase 3 signaling

Molecular Brain, 2012
Accumulated evidence has suggested that potentiation of cortical GABAergic inhibitory neurotransmission may be a key mechanism in the treatment of schizophrenia. However, the downstream molecular mechanisms related to GABA potentiation remain unexplored.

Seminars in epileptology: How to diagnose status epilepticus in adults and children

Epileptic Disorders, EarlyView.
Abstract Status epilepticus (SE) can be regarded as the most severe expression of seizure activity characterized by a low probability of spontaneous cessation and mechanisms leading to metabolic and inflammatory derangements with increased risk of brain damage, alterations of neural networks, and potentially life‐threatening systemic complications ...
