Using two flexible Schiff bases, H2L1 and H2L2, two new cobalt II (Co(II))-coordination compounds, namely, Py3CoL1 (1) and Py3CoL2 (2) (Py=pyridine, L1=3,5-ClC6H2(O)C=NC6H3(O)-4-NO2, L2=3,5-BrC6H2(O)C=NC6H3(O)-4-NO2) have been synthesized under solvothermal conditions. Single crystal X-ray structural ana...
Existen pocos estudios científicos que demuestren el valor terapéutico de las plantas usadas en la medicina tradicional centroamericana para tratar el envenenamiento ofídico. En este estudio se evaluó la capacidad de los extractos etanólicos de nueve plantas de uso etnomédico en Centroamérica (Aca...
ABSTRACT OBJECTIVE The objective of this study has been to analyze whether fine particulate matter (PM2.5), as well as its synergistic effect with maximum temperature, humidity, and seasons, is associated with morbidity and mortality from cardiovascular diseases. METHODS This is an ecological study o...

Chitinases are hydrolases that degrade chitin, a polymer of N-acetylglucosamine linked β(1-4) present in the exoskeleton of crustaceans, insects, nematodes and fungal cell walls. A metagenome fosmid library from a wastewater-contaminated soil was functionally screened for chitinase activity leading ...

Currently, the potential for cardiovascular (CV) stress-induced risk is primarily based on the theoretical (obvious) side effects of stress on the CV system. Salivary cortisol and α-amylase, produced respectively by the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic-adrenomedullary (S...

ABSTRACT Guava (Psidium guajava L.) is a native fruit of the American tropics with commercial applications for its taste, flavor and aroma. Numerous pharmacological uses have been described for it, such as the antiseptic effect of its leaves, the use of the fresh fruit and tea from its leaves for the tre...
Abstract Genetic variations observed in cytokines affect periodontitis susceptibility. The aim of this study was to investigate interleukin(IL)-6(-174) and IL-10(-597) gene polymorphisms in generalized aggressive periodontitis (GAgP) patients. Also, we aimed to evaluate the effects of IL-6 and IL-10 gene...
