ABSTRACT
Several triggers can trigger a migraine attack, including food. By the way, food only triggers headache in migraine sufferers. The foods that most trigger headache attacks are these: cheese, chocolate, citrus fruits and some sweet fruits, such as watermelon.
Vários gatilhos podem desencadear uma crise de enxaqueca, incluindo alimentos. Aliás, a comida só provoca dor de cabeça em quem sofre de enxaqueca. Os alimentos que mais desencadeiam as crises de dor de cabeça são estes: queijo, chocolate, frutas cítricas e algumas frutas doces, como a melancia.

Abstract Background: Studies have persuasively demonstrated that citrulline has a key role in the arginine-nitric oxide system, increasing nitric oxide bioavailability, an important mediator of peripheral vasodilation. Objective: To analyze the inter-individual post-exercise hypotension responsiveness following acute citrulline supplementation in hypertensives. Methods: Forty hypertensives were randomly assigned to one of the four experimental groups (control-placebo, control-citrulline, exercise-placebo, and exercise-citrulline). They ingested placebo or citrulline malate [CM] (6 grams). During the exercise session, individuals performed 40 minutes of walking/running on a treadmill at 60-70% of HR reserve. For the control session, the individuals remained seated at rest for 40 minutes. Office blood pressure (BP) was taken every 10 minutes until completing 60 minutes after the experimental session. The ambulatory BP device was programmed to take the readings every 20 minutes (awake time) and every 30 minutes (sleep time) over the course of 24 hours of monitoring. Statistical significance was defined as p < 0.05. Results: Unlike the other experimental groups, there were no "non-responders" in the exercise/citrulline (EC) for "awake" (systolic and diastolic BP) and "24 hours" (diastolic BP). The effect sizes were more consistent in the EC for systolic and diastolic ambulatorial BP response. The effects were "large" (> 0.8) for "awake", "asleep", and "24 hours" only in the EC for diastolic BP. Conclusion: CM supplementation can increase the post-exercise hypotensive effects in hypertensives. In addition, the prevalence of non-responders is lower when associated with aerobic exercise and CM supplementation.
Resumo Fundamento: Estudos demonstraram de maneira persuasiva que a citrulina tem um papel fundamental no sistema arginina-óxido nítrico, aumentando a biodisponibilidade do óxido nítrico, um importante mediador da vasodilatação periférica. Objetivo: Analisar a responsividade interindividual da hipotensão pós-exercício após suplementação aguda com citrulina em hipertensos. Métodos: Quarenta hipertensos foram aleatoriamente designados para um dos quatro grupos experimentais (controle-placebo, controle-citrulina, exercício-placebo e exercício-citrulina). Eles ingeriram placebo ou citrulina malato [CM] (6 gramas). Durante a sessão de exercício, os indivíduos realizaram 40 minutos de caminhada/corrida em esteira a 60-70% da FC de reserva. Para a sessão de controle, os indivíduos permaneceram sentados em repouso por 40 minutos. A medida da pressão arterial (PA) no consultório foi realizada a cada 10 minutos até completar 60 minutos após a sessão experimental. O dispositivo ambulatorial de PA foi programado para fazer as leituras a cada 20 minutos (tempo de vigília) e a cada 30 minutos (tempo de sono) ao longo de 24 horas de monitoramento. A significância estatística foi definida como p < 0,05. Resultados: Diferentemente de outros grupos experimentais, não houve "não respondedores" no exercício/citrulina (EC) para "acordado" (PA sistólica e diastólica) e "24 horas" (PA diastólica). Os tamanhos de efeito foram mais consistentes no EC para a resposta sistólica e diastólica da PA ambulatorial. Os efeitos foram "grandes" (> 0,8) para "acordado", "dormindo", e para "24 horas" apenas no EC para a PA diastólica. Conclusão: A suplementação com CM pode aumentar os efeitos hipotensivos pós-exercício em hipertensos. Além disso, a prevalência de "não respondedores" é menor quando associada ao exercício aeróbico e à suplementação com CM.

Objective To investigate the effects of rhubarb combined with glutamine on repair of gut mucosal barrier injury after gastrointestinal surgery in rats. Methods Fifty male healthy Sprague-Dawley(SD)rats were randomly divided into five groups:control(C group),enteral nutrition(EN group),rhubarb with EN(R-EN group), glutamine with EN(G-EN group)and rhubarb combined with glutamine and EN(R-G-EN group)groups(each n=10). The rats of C group received no treatment and were fed normally. Cecectomy and gastrostomy were performed in EN,R-EN,G-EN and R-G-EN groups,and in 24 hours after surgery,they were interfered with the use of amoxicillin 50 mg/d and metronidazole 20 mg twice a day. From the first day after operation,each group was treated with the same prescription of enteral isocaloric and isonitrogenous nutrition for consecutive 7 days. Seven days later, under anaesthesia,laparotomy was performed,and a specimen of 1 cm intestinal segment was taken from the terminal 5 cm long ileum for all the groups;under the light microscope,the morphological examination of intestinal mucosal epithelial tight junctions(including villus height and mucosal thickness)was carried out. For each group,enzyme-linked immunosorbent assay(ELISA)was used to measure the levels of plasma citruline and D-lactate,and the serum concentration of TNF-αwas detected by utilizing double antibody ABC-ELISA. Results The levels of D-lactate and TNF-αin EN,R-EN,G-EN and R-G-EN groups were obviously higher than those in C group(all P0.05). Conclusion The application of rhubarb combined with glutamine can protect gut mucosa,reduce the level of inflammatory reaction and elevate the level of plasma citruline, that is beneficial to the repair of gut mucosal barrier injury and its functional recovery after gastrointestinal surgery in rats.
ABSTRACT
Objective To examine the role of synthetic cyclic citrullinated peptide (CCP) in T cell autoreactivity in rheumatoid arthritis (RA) by detecting T cell proliferation. Methods Twenty-nine RA, 8 primary Sjo gren syndrome (pSS) and 16 osteoarthritis (OA) patients were included in this study. Proliferation of T cells was measured by methyltetiazolium incorporation following incubation with CCP. Results T cell response to CCP was more common in RA patients than in controls. The response rate to CCP was higher in late RA than in early RA. However, the response wasn′t associated with disease activity. A strong association between T cell proliferation and RF, anti-CCP antibody was observed. Conclusions T cell proliferation in response to CCP was found in the majority of RA patients, even in early RA, suggesting that the citrullinated peptide play an important role in the pathogenesis of RA.
