O presente artigo trata-se de uma revisão de literatura que expõe sobre o conhecimento de patologias em pontes, fortalecendo, assim, o acervo literário existente. A ausência de manutenção é uma das condições que mais ocasionam o surgimento de manifestações patológicas, tais como: fissuras e trincas, flambagem, corrosão, desagregação, eflorescência e manchas. Dentro desse contexto, analisou-se diversos artigos e produções científicas que apresentavam no seu escopo patologias em pontes. Então, através de estudos de casos, as manifestações patológicas encontradas foram esclarecidas e aprofundadas, de modo a encontrar os motivos a que levaram a essas patologias. Por fim, chegou-se a conclusão de que as pontes de concreto armado apresentam como principais patologias as fissuras, já as pontes metálicas apresentam a corrosão, química ou eletroquímica, como principal patologia, além da fadiga e a deformação.
densidade aparente das madeiras, indicando, dessa forma, que a ordem da resistência à flexão das espécies apresenta relação direta entre essas duas propriedades.
GHSr signaling is involved in the regulation of energy homeostasis. LEAP2, a recentlydiscovered peptide hormone, counteracts the effects of ghrelin. This study sought to evaluatethe effects of perinatal LEAP2 exposure in young rat offspring. For this, two protocols weredesigned to assess the roles of GHSr antagonism during the pregnancy and during thelactation. Sex-specific impacts on AUC and peak-responses of glucose tolerance tests werepresented. However, no differences were detected in the blood glucose of mixed meal fedanimals. In conclusion, perinatal LEAP2 exposure could impact the glucose-stimulatedinsulin secretion in young rats.
Dietary restriction during pregnancy and puberty is a risk factor to hypertension onset atadulthood. The aim of this study was to evaluate the effect of maternal malnutrition duringlactation on cardiovascular parameters, in both sexes of rat pups at 120-day-old. Maternalfood restriction lead to arterial hypertension, baroreflex impairment, cardiac remodeling andincreased collagen deposition in the aorta, in adult male offspring. The females did not showfunctional or morphological disruptions. Together, these results show that maternal foodrestriction during lactation promotes cardiometabolic programming, generating cardiovascularalterations in male adult rat offspring, however female offspring present some kind ofcardioprotective effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
