Implementation science: Epidemiology and feeding profiles of the Chagas vector Triatoma dimidiata prior to Ecohealth intervention for three locations in Central America.

The Ecohealth strategy is a multidisciplinary data-driven approach used to improve the quality of people's lives in Chagas disease endemic areas, such as regions of Central America. Chagas is a vector-borne disease caused by the parasite Trypanosoma cruzi. In Central America, the main vector is Triatoma dimidiata.

Information to act: household characteristics are predictors of domestic infestation with the Chagas vector Triatoma dimidiata in Central America.

The interruption of vectorial transmission of Chagas disease by Triatoma dimidiata in central America is a public health challenge that cannot be resolved by insecticide application alone. In this study, we collected information on previously known household risk factors for infestation in 11 villages and more than 2,000 houses in Guatemala, Honduras, and El Salvador, and we constructed multivariate models and used multimodel inference to evaluate their importance as predictors of infestation in the region. The models had moderate ability to predict infested houses (sensitivity, 0.

Docking Studies of Methylthiomorpholin Phenols (LQM300 Series) with Angiotensin-Converting Enzyme (ACE).

A main target in the treatment of hypertension is the angiotensin-converting enzyme (ACE). This enzyme is responsible for producing angiotensin II, a potent vasoconstrictor. Therefore, one of the targets in the treatment of hypertension is to inhibit ACE activity.

Antihypertensive and antiarrhythmic properties of a para-hydroxy[bis(ortho-morpholinylmethyl)]phenyl-1,4-DHP compound: comparison with other compounds of the same kind and relationship with logP values.

A new para-hydroxy[bis(ortho-morpholinylmethyl)]phenyl-1,4-DHP substituted compound, (4-(4-hydroxy-3,5-bis(morpholin-4-ylmethyl)phenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acid diethyl ester, LQM300), with antihypertensive and antiarrhythmic properties, has been synthesized. Four pKa values of this compound have been determined with the aid of the program SQUAD, at pseudo-physiological conditions (T = 37 degrees C and I = 0.15 M) by UV spectrophotometry and at T = 25 degrees C and I = 0.

Synthesis and antihypertensive effects of new methylthiomorpholinphenol derivatives.

We present in this work the synthesis and cardiovascular effects of new methylthiomorpholine compounds and they were compared with cardiovascular drugs such as captopril, losartan and omapatrilat.
