In this work, the effect of Ag-Fau Y zeolite as a material to inhibit the growth of bacteria on cotton fabric was studied. Different concentrations of silver in the culture of E. coli by the Kirby-Bauer Method were explored. The relevance of this work focuses on the growing concern about the resistance that many bacteria present to antibiotics. In...

Environmental pollution nowadays has not only a direct correlation with human health changes but a direct social impact. Epidemiological studies have evidenced the increased damage to human health on a daily basis because of damage to the ecological niche. Rapid urban growth and industrialized societies importantly compromise air quality, which can...

Obesity and dyslipidemias are both signs of metabolic syndrome, usually associated with ventricular arrhythmias. Here, we tried to identify cardiac electrical alteration and biomarkers in nonobese rats with metabolic syndrome (MetS), and these findings might lead to more lethal arrhythmias than obese animals. The MetS model was developed in Wistar...

En este trabajo se presenta un modelo matemático para potenciales de acción (PA), similar al modelo de Hodgkin y Huxley, utilizando la Ley de Acción de Masas para determinar las corrientes iónicas que atraviesan la membrana en cada célula excitable. Este modelo permite visualizar que la cinética de los canales iónicos (las velocidades de transición...

In this work it proposes a mathematical model for ion channels based on two concepts, the Hodgkin and Huxley's as well as the Law of Mass Action in addition, we consider the kinetics of channels as a dynamic process of Markov`s chain. With the previous premises, a system of differential equations is proposed that when it is solved, all properties o...

Heart rate variability (HRV) is highly influenced by the Autonomic Nervous System (ANS). Several illnesses have been associated with changes in the ANS, thus altering the pattern of HRV. However, the variability of the heart rhythm is originated within the Sinus Atrial Node (SAN) which has its own variability. Still, although both oscillators produ...

When a complex dynamical system is externally disturbed, the statistical moments of signals associated to it can be affected in ways that depend on the nature and amplitude of the perturbation. In systems that exhibit phase transitions, the statistical moments can be used as Early Warnings (EW) of the transition. A natural question is thus to wonde...

According to the American Diabetes Association (ADA), the side effects of diabetes mellitus have recently increased the global health expenditure each year. Of these, the early diagnostic can contribute to the decrease on renal, cardiovascular, and nervous systems complications. However, the diagnostic criteria, which are commonly used, do not sugg...

Obesity is considered a major public health problem worldwide. Metabolic syndrome is a cluster of signs that increases the risk of developing cardiovascular disease and type 2 diabetes mellitus (T2DM). The main characteristics of metabolic syndrome are central obesity, dyslipidemia, hypertension, hyperinsulinemia, and insulin resistance. It is clea...

In the last ten years, the incidences of metabolic syndrome and supraventricular arrhythmias have greatly increased. The metabolic syndrome is a cluster of alterations, which include obesity, hypertension, hypertriglyceridemia, glucose intolerance and insulin resistance, that increase the risk of developing, among others, atrial and nodal arrhythmi...

4-aminopyridine (4-AP) is commonly used to block the transient outward potassium current, I(to), in cardiac and noncardiac tissues. In the present work, we found that 4-AP inhibited the rapid component of the delayed rectifier potassium current, I(Kr), in rabbit-isolated sinoatrial node myocytes by 25% (1 mM) and 51% (5 mM) and inhibited the slow c...

The Dader Method used for pharmacotherapeutic follow-up has been a suitable course of action to detect and to solve problems concerned with medication. It is easily fitted to local conditions of rural communities. The objective of this study was to evaluate the appropriateness of the Dader Method in a rural community of Mexico. The pharmaceutic ser...

El Método Dáder para el seguimiento farmacoterapéutico ha sido una herramienta que permite detectar y solucionar problemas relacionados con la medicación y puede adaptarse a las condiciones de la población mexicana que vive en comunidades rurales. El programa se ofreció a 300 infantes de la comunidad de Santa María Acuexcomac, de los cuales solo 10...
