The purpose of this study was to analyze the effect of Zn nutritional status on the content of pigments, nonstructural carbohydrates, foliage proteins and amino acids of the pecan tree, as possible bioindicators of Zn deficiency. The experimental design was completely random with three Zn nutritional statuses: Normal, Intermediate and Deficient, being selected considering visual symptomatology. On all three nutritional statuses, the concentration of photosynthetic pigments was determined as well as of total soluble proteins and amino acids. Obtained results indicate that Zn deficient nutritional status was characterized by minimum photosynthetic pigment, protein concentrations, maximum amino acid and nonstructural carbohydrate concentrations. While the normal Zn nutritional status presented maximum photosynthetic pigments, proteins concentrations, minimum amino acids and carbohydrate concentrations. On the other hand, intermediate Zn nutritional status was characterized by a medium level between the other two Zn nutritional statuses. Finally, we stress the fact that pigments, proteins, amino acids and nonstructural carbohydrates may be good physiological indicators related to Zn nutritional status on pecan trees.

High anxiety levels during pregnancy commonly lead to clinical complications that affect the mother/child’s prenatal and perinatal health. Such complications are thought to result from combining deficiencies of the endocrine milieu and decreased immune tolerance that support pregnancy. It is yet unclear whether pregnant women subjected to moderate anxiety develop a similar state of endocrine deficits and compromised immune tolerance. Here, we evaluated this issue by monitoring endocrine and immune parameters during pregnancy in a sample of women suffering of moderate anxiety. The health of mothers and children, as well as the outcome of the pregnancies were also revised and recorded. Moderately anxious pregnant women present increments of state anxiety, serum cortisol and progesterone, but not of estradiol, as pregnancy progressed. No variations of leukocyte anti- and pro-inflammatory cytokine mRNA expression were found along pregnancy. However, these pregnant women did show an increased frequency of gestational and perinatal complications, conditions that had no major consequences for their health and that of their children at birth. Hence, moderate anxiety renders the mother to be susceptible to develop diseased states during or by the end of pregnancy, while keeping the endocrine milieu and immune tolerance reasonably in place.

Timely reperfusion for ST-segment elevation myocardial infarction:Effect of direct transfer to primary angioplasty on time delays and clinical outcomes

引用

World Journal of Cardiology 2014年第6期6卷 424-433页

作者： Rodrigo Estévez-Loureiro ángela López-Sainz Armo Pérez de Prado Carlos cuellas Ramón Calvio Santos Norberto Alonso-Orcajo Jorge Salgado Fernández Jose Manuel Vázquez-Rodríguez Maria López-Benito Felipe Fernández-Vázquez Division of Cardiology Complejo Asistencial Universitario de León (CAULE)24071 LeonSpain Division of Cardiology Complejo Hospitalario Universitario A Coru?a (CHUAC)15006 La Coru?aSpain

Primary percutaneous coronary intervention(PPCI) is the preferred reperfusion therapy for patients presenting with ST-segment elevation myocardial infarction(STEMI) when it can be performed expeditiously and by experienced operators. In spite of excellent clinical results this technique is associated with longer delays than thrombolysis and this fact may nullify the benefit of selecting this therapeutic option. Several strategies have been proposed to decrease the temporal delays to deliver PPCI. Among them,prehospital diagnosis and direct transfer to the cath lab,by-passing the emergency department of hospitals,has emerged as anattractive way of diminishing delays. The purpose of this review is to address the effect of direct transfer on time delays and clinical events of patients with STEMI treated by PPCI.

Meningoencephalitis due to Listeria monocytogenes in a Young Immunocompetent Patient: Case Report with Literature Review

引用

Advances in Infectious Diseases 2024年第1期14卷 213-219页

Meningoencephalitis secondary to Listeria monocytogenes (L. monocytogenes) mainly affects newborns, the elderly and immunocompromised people;there are extremely rare cases in which said infection occurs in immunocompetent individuals. We present the case of a young adult patient without immunocompromise, who developed meningoencephalitis due to L. monocytogenes;This case is exceptional, since it occurred in an individual outside the classic age group, in addition to not having risk factors, which is why it should be considered an atypical causal agent.
