1. Fire response of a 3D multi-storey building with buckling restrained braces
Abstract This paper investigates the performance of a three-dimensional multi-storey structure with Buckling Restrained Brace system (BRBs) under fire condition, using a sequentially coupled nonlinear thermal stress analysis. Efficiency of using BRBs in enhancing the strength and stiffness of a structural frame is compared with that of Ordinary Concentricall

2. Effect of chronic stress on implant osseointegration into rat's mandible
PURPOSE:To compare chronic physical stressed with normal tense animals regarding implant osseointegration in the rat mandible.METHODS:Thirty six Wistar rats were anesthesiaded and blunt instruments were used to expose and empty their alveolar inferior nerve. One implant (2.2 x 4mm) was installed into the mandibular canal. Following 72 hours, all rats were eq

3. Acute stress-induced antinociception is cGMP-dependent but heme oxygenase-independent
Endogenous carbon monoxide (CO), which is produced by the enzyme heme oxygenase (HO), participates as a neuromodulator in physiological processes such as thermoregulation and nociception by stimulating the formation of 3′,5′-cyclic guanosine monophosphate (cGMP). In particular, the acute physical restraint-induced fever of rats can be blocked by inhibiti

4. Evaluation of the protective effects of tocotrienol-rich fraction from palm oil on the dentate gyrus following chronic restraint stress in rats
A exposição crônica ao estresse por restrição causa série de alterações morfológicas na formação do hipocampo de ratos. Tocotrienol, uma isoforma da vitamina E, apresenta inúmeros benefícios para a saúde, diferente do tocoferol. Estudos recentes demonstraram que o tocotrienol impediu alterações induzidas por estresse na mucosa gástrica, indi

5. Brief daily postpartum separations from the litter alter dam response to psychostimulants and to stress
Neonatal handling induces several behavioral and neurochemical alterations in pups, including decreased responses to stress and reduced fear in new environments. However, there are few reports in the literature concerning the behavioral effects of this neonatal intervention on the dams during the postpartum period. Therefore, the aim of the current study was

6. Animal models of anxiety disorders and stress
Anxiety and stress-related disorders are severe psychiatric conditions that affect performance in daily tasks and represent a high cost to public health. The initial observation of Charles Darwin that animals and human beings share similar characteristics in the expression of emotion raise the possibility of studying the mechanisms of psychiatric disorders i

7. Effects of simultaneous exposure to stress and nicotine on nicotine-induced locomotor activation in adolescent and adult rats
Preclinical studies have shown that repeated stress experiences can result in an increase in the locomotor response to the subsequent administration of drugs of abuse, a phenomenon that has been termed behavioral cross-sensitization. Behavioral sensitization reflects neuroadaptive processes associated with drug addiction and drug-induced psychosis. Although

8. Investigação das alterações do consumo de alimento palatável induzidas por trauma precoce em ratas fêmeas
Introduction: Chronic stress in adulthood increases anxiety and prones the individuals to use palatable foods as ¿comfort foods¿, which seems to be mediated by an altered functioning of the hypothalamus-pituitary-adrenal axis (HPA). We aimed at verifying if early life stress also affects anxiety, feeding behavior and stress responses in adult female rats.

9. Estresse pré-natal e suas repercussões sobre o cuidado maternal e comportamento de ratos a curto e a longo prazo
In humans and rodents, stress during pregnancy has produced offspring with high levels of anxiety, impaired learning and memory, changes in maternal care and social behavior deficits. Most prenatal stress protocols have attributed their results to the vulnerability of the intrauterine period. However, studies show that the consequences caused by this action

10. INTERAÇÕES ENTRE O ESTRESSE REPETIDO E CLOMIPRAMINA: DIFERENNTES RESPOSTAS EM RATOS MACHOS E FÊMEAS / INTERACTION BETWEEN REPEATED STRESS AND CLOMIPRAMINE: DIFERENCE RESPONSE IN MALE AND FEMALE RATS
O estresse pode ser definido como uma variedade de estímulos fisiológicos e psicológicos que podem ter efeitos diretos ou indiretos sobre a função corporal. Neste contexto o estresse repetido ou situações estressantes podem induzir ansiedade e depressão. Diferentes respostas quanto ao estresse repetido e tratamento antidepressivo são observadas em m

11. Influência dos hormônios sexuais na analgesia induzida pelo estresse / Influence of sex hormones in stress-induced analgesia
Temporomandibular disorders comprehend a variable group of conditions which result in joint and/or muscle pain and contribute to the development of acute pains, being more prevalent in women than men, especially during the reproductive period. They involve the muscles of mastication and temporomandibular joint (ATM), being usually associated with inflammator

12. Efeito neuroprotetor da catequina e do estresse de imobilizaÃÃo subcrÃnico na DoenÃa de Parkinson experimental. / Neuroprotector effect of catechin and restraint stress in experimental Parkinsonâs Disease.
A DoenÃa de Parkinson (DP) Ã uma desordem neurodegenerativa caracterizada pela perda de neurÃnios dopaminÃrgicos na substancia nigra (SN). Estudos epidemiolÃgicos sugerem uma associaÃÃo entre estresse, depressÃo e DP. Agentes antioxidantes tem sido relatados como capazes de mudar o curso da doenÃa, bloqueando a neurodegeneraÃÃo dopaminÃrgica. Com
