1. Short-term oral administration of risperidone induces pancreatic damage and hyperamylasemia in Sprague-dawley rats
Risperidone is an atypical antipsychotic acting mainly as a dopamine D2 and serotonin 5-HT2 receptors antagonist prescribed in the treatment of schizophrenia and various affective disorders. Risperidone has been reported to be associated with weight gain, panreatitis and type 2 diabetes mellitus. Various mechanisms of risperidone-induced toxicities have been

2. Association between serotonin 2C receptor gene (HTR2C) polymorphisms and psychopathological symptoms in children and adolescents
Serotonin 2C receptors (5HT2C) are involved in serotonin-driven dynamic equilibrium adjustments responsible for homeostatic stability in brain structures that modulate behavior and emotions. Single nucleotide polymorphisms (SNPs) from the serotonin 2C receptor gene (HTR2C) have been associated with several neurological and mental disorders, including abnorma

3. ADME studies and preliminary safety pharmacology of LDT5, a lead compound for the treatment of benign prostatic hyperplasia
This study aimed to estimate the absorption, distribution, metabolism and excretion (ADME) properties and safety of LDT5, a lead compound for oral treatment of benign prostatic hyperplasia that has previously been characterized as a multi-target antagonist of α1A-, α1D-adrenoceptors and 5-HT1A receptors. The preclinical characterization of this compound co

4. Association of terpinolene and diclofenac presents antinociceptive and anti-inflammatory synergistic effects in a model of chronic inflammation
Pharmacological treatment of inflammatory pain is usually done by administration of non-steroidal anti-inflammatory drugs (NSAIDs). These drugs present high efficacy, although side effects are common, especially gastrointestinal lesions. One of the pharmacological strategies to minimize such effects is the combination of drugs and natural products with syner

5. Selective 5-HT7 receptor agonists LP 44 and LP 211 elicit an analgesic effect on formalin-induced orofacial pain in mice
ABSTRACT The most recently identified serotonin (5-HT) receptor is the 5-HT7 receptor. The antinociceptive effects of a 5-HT7 receptor agonist have been shown in neuropathic and inflammatory animal models of pain. A recent study demonstrated the functional expression of 5-HT7 receptors in the substantia gelatinosa (SG) of the trigeminal subnucleus caudalis,

6. Efeitos da restrição proteica gestacional em hipocampo de ratos machos adultos : avaliação da estrutura dendrítica tridimensional, do comportamento e de componentes neuroquímicos = Effects of gestational protein restriction in hippocampus of adult male rats / Effects of gestational protein restriction in hippocampus of adult male rats : evaluation of three-dimensional dendritic structure of hippocampal neurons, behavior and neurochemical components
Studies have demonstrated that maternal nutritional restriction during pregnancy or in early postnatal life results in hippocampus cognitive impairment and structural abnormalities in the 16-wk-old offspring. In an attempt to analyze whether gestational protein restriction might induce learning and memory impairment associated with structural changes in the

7. Efeito da microinjeção do agonista dos receptores 5-HT1A, F15599, na região ventro-orbital do córtex pré-frontal no comportamento agressivo de camundongos machos submetidos à provocação social
The serotonergic system has long been linked to aggressive behavior and particularly 5-HT1A receptor subtype is involved in modulation of aggressiveness. Previous studies using agonists that act selectively on these receptors showed both reduction and increased aggression. It is known that these receptors are found in several brain regions where they act as

8. O bloqueio dos receptores 5-HT2 da substância cinzenta periaquedutal suprime o efeito ansiolítico resultante do antagonismo dos receptores 5-HT1A do núcleo mediano da rafe em camundongos / Blockade of 5-HT2 receptors in the periaqueductal grey matter (PAG) abolishes the anxiolytic-like effect of 5-HT1A receptor antagonism in the median raphé nucleus in mice. 2011.
Várias evidências apontam o envolvimento de neurônios serotoninérgicos do núcleo mediano da rafe (NMnR) na ansiedade. Sabe-se que o bloqueio dos autorreceptores somatodendríticos dos núcleos da rafe aumenta a taxa de disparo dos neurônios serotoninérgicos, promovendo a liberação de serotonina em sítios pós-sinápticos como amígdala, hipocampo e

9. Envolvimento de receptores NK-1 e NK-3 no comportamento defensivo induzido pela estimulação elétrica da substância cinzenta periaquedutal dorsal / Involvement of NK-1 and NK-3 receptors on the defensive behavior induced by electrical stimulation of the dorsal periaqueductal gray.
A substância cinzenta periaquedutal dorsal (SCPd) é considerada uma das principais estruturas do teto mesencefálico envolvida no substrato neural da aversão a estímulos proximais. GABA e 5-HT são apontados como neurotransmissores envolvidos na modulação das respostas defensivas elaboradas na SCPd. Recentemente, mecanismos neurocininérgicos também t

10. Efeito ansiolítico do ondansetron, antagonista dos receptores 5-HT3, injetado na amídala de camundongos submetidos à exposição e reexposição no labirinto em cruz elevado
Against of stimuli that are dangerous, animals manifest defense reactions that cause fear and anxiety. These stimuli activate the serotonergic system, which sends projections to structures involved in defense mechanisms such as the septum, hypothalamus, hippocampus, amygdala and periaqueductal gray modulates the behavioral changes that can be characterized a

11. Avaliação do papel da 5-hidroxitriptamina (5-HT) no processamento periférico da resposta nociceptiva
5-Hydroxytryptamine (5-HT, serotonin) is a cell-derived vasoactive amine, released primarily by platelets (in humans), mast cells (in rodents) and endothelial cells. It is a regulator of smooth muscle in the cardiovascular and gastrointestinal systems, an enhancer of platelet aggregation, and a neurotransmitter in the central nervous system. Although 5-HT is

Anxiety is among the most common chronic disease in the world. In Brasília city (capital of Brazil), anxiety disorders affect 12.1 % of population and are the most prevalent psychiatry disease. Since the introduction of benzodiazepines in the 1960s, they have been the most commonly prescribed treatment for anxiety disorders. However, their side-effects such
