A epidemia do SARS-CoV-2 (novíssimo coronavírus) provocou uma grave crise infecciosa, ocasionando repercussões negativas, tais como falecimentos, desequilíbrio econômico e diversas crises de natureza mental física. Pessoas que apresentaram condições psicológicas físicas preexistentes foram especialmente impactadas. alteração da rotina causada pela pandemia restringiu o acesso aos serviços saúde à assistência social, influenciando as práticas alimentares um mecanismo controle emocional, em...
Few data are available on adolescent users because most behavioral studies anabolic-androgenic steroids (AAS) abuse have been performed in adults. Studies evaluating the impact of long-term effects AAS prepubertal phase even more uncommon. Accordingly, this study was developed to test hypothesis that changes induced by use during may be noted adult when treatment cycle is discontinued. Therefore, not only but also possible autonomic and electrolyte disorders were evaluated. For purpose, we...
The plant Hydrocotyle umbellata L., Araliaceae (water pennywort), is widely used in Brazilian folk medicine to reduce anxiety. This work investigates the anxiolytic-like effects of ethanol extract from H. subterraneous parts as well extract's other putative central nervous system that could justify its common use. Oral dosing (0.3 and 1 g/kg) clearly showed an profile elevated plus maze test where it increased percentage entries into time spent open arms maze. In marble-burying test, induced...
Introduction: Isometric strength training (IST) is an important component of different types sport and others activities daily life. However, until the present moment, no studies have linked isometric with acetylcholinesterase (AChE) activity changes. Objective: We evaluated effects IST on muscular AChE strength. Materials Methods: Wistar rats (n =20) were divided into 2 groups: Control group (Ctr) (sedentary) trained (Tr) (submitted to 8 weeks training). The muscle in solear (SOL) Extensor...
Vasopressin (AVP) and oxytocin (OXT) are neuropeptides produced by magnocellular neurons (MCNs) of the hypothalamus secreted through neurohypophysis to defend mammals against dehydration. It was recently demonstrated that MCNs also project limbic structures, modulating several behavioral responses. We found 24 h water deprivation (WD) or salt loading (SL) did not change exploration anxiety-like behaviors in elevated plus maze (EPM) test. However, rats deprived for 48 showed reduced open...
We hypothesized that perinatal manipulations of the nitrergic system would affect adult animal behaviors.We tested this hypothesis by perinatally administering N(G)-Nitro-L-arginine methyl ester (L-NAME), a non-specific antagonist nitric oxide synthase for 15 days and assessed anxiety- depression-like behaviors in mice. At 70 age, mice were subjected to battery tests consisting open-field, light/dark box, forced swim, tail-flick tests. The performed at two-day intervals, order within was...
We have shown that ovarariectomized (OVX) rats exhibited higher salt intake compared to estrogen‐replaced (OVX+E2) particularly in models of induction sodium appetite dependent on angiotensin II and low plasma levels. This result was ascribed enhanced AT1 receptors activity. In male we reported repeated 5‐HT1A agonist administration reduced response related somatodendritic autoreceptor desensitization. Therefore, investigate the effect systemic acute chronic 8‐OH‐DPAT normally hydrated or...
Serotonin exerts an important role in the central nervous system embryogenesis of mammals, influencing directly several brain systems ontogeny. Therefore, we investigated effect neonatal Fluoxetine (FLU), a selective serotonin reuptake inhibitor, on behavioral expression adult male Swiss mice. For this purpose, three groups (n=6 each, and ~35g) pregnant female mice were mated. The offspring obtained was treated with FLU (1mg/kg, s.c.) from 5 th at 15 post‐natal day. On 16 day, puppies...
The paternal environmental factors before conception and during sperm development determine the health of offspring in later life. Thus, aim our study was to verify how hyperandrogenism is able change behavioral parameters mice's adulthood. For this purpose, two groups (n=6 each, ~35g) male Swiss mice were randomly divided into groups. control treated with peanut oil, while group received testosterone cypionate (7.5mg/kg, s.c. ) twice a week for five weeks. After period, these animals mated...
Serotonin exerts a significant role in the mammalian central nervous system embryogenesis and brain ontogeny. Therefore, we investigate effect of neonatal treatment d-fenfluramine (d-FEN), serotonin (5-HT) releaser, on behavioral expression adult male Swiss mice. For this purpose, divided pregnant female mice into two groups (n = 6 each ~35 g). Their offspring were treated with d-FEN (3 mg/kg, s.c.) from postnatal days (PND) 5 to 20. At PND 21, one puppy litter was euthanized; midbrain...
