ANTI-HYPERTENSION DRUGS: ACTION IN THE ORGANISM AND ENVIRONMENTAL CONTAMINATION
Journal Title: Periódico Tchê Química - Year 2018, Vol 15, Issue 30
Abstract
Systemic Arterial Hypertension is an ascending pathology that is being treated more and more through antihypertensive drugs. The most commonly used are: Enalapril, Captopril, Losartan, Propranolol, Atenolol, and in addition, Furosemide and Hydrochlorothiazide are prescribed and are used as a secondary medicine. The abusive use may lead to contamination of water resources due to urine excretion and improper disposal of these drugs after the expiration date. In addition to environmental awareness at the time of inadequate disposal, the main problem is in sewage treatment plants that do not have the necessary resources to control contamination, and many drugs are not yet identifiable by current methods. Some studies have already confirmed this contamination, but research is recent.
OPTIMIZATION OF SEMICONDUCTOR PRESSURE TRANSDUCER WITH SENSITIVE ELEMENT BASED ON “SILICON ON SAPPHIRE” STRUCTURE
The paper is devoted to the study of the process of optimizing the semiconductor strain-gauge transducer on the structure of the SOS. As an object of the study, an elastic membrane-type element with a semiconductor strai...
REDUCTION OF THE ACTUAL MODULUS OF ELASTICITY TO THE DESIGN TEMPERATURE
Reduction of the actual modulus of elasticity of road pavement to the design temperature is a rather labor intensive task. Besides, it depends on the weather and climatic conditions. Here we present the result of general...
RATIONALE FOR WATER SOIL WASHING TECHNOLOGIES BY GROWTH REGULATION
When irrigation of land in the arid zone, one of the mandatory elements for maintaining the water-salt balance is soil washing. At present, washing standards are calculated and recommended for different soils. However, t...
CONFORMATIONAL STABILITY ORDER OF ACYCLIC ORGANIC MOLECULES REVISITED: A COMPUTER-BASED PROJECT IN LEARNING STEREOCHEMISTRY
Learning stereochemistry today, especially on the topic of conformational stability, seems to generalize anti, gauche, eclipsed conformations as a general stability order for all acyclic organic molecules. This may be du...
MODIFICATION OF EXPANDED PERLITE WITH ORTHOPHENANTHROLINE FOR FORMATION OF ACTIVE SITES FOR ACID DYES: PREPARATION AND CHARACTERIZATION
The expanded perlite (aluminosilicate naturally acid) has been modified with orthophenanthroline (Lewis base). The material was characterized by TG/DTA, XRD and IR. The thermogravimetric curve of the modified expanded pe...
